BACKGROUND: After a person has been injured, prehospital administration of plasma in addition to the initiation of standard resuscitation procedures in the prehospital environment may reduce the risk of downstream complications from hemorrhage and shock. Data from large clinical trials are lacking to show either the efficacy or the risks associated with plasma transfusion in the prehospital setting. METHODS: To determine the efficacy and safety of prehospital administration of thawed plasma in injured patients who are at risk for hemorrhagic shock, we conducted a pragmatic, multicenter, cluster-randomized, phase 3 superiority trial that compared the administration of thawed plasma with standard-care resuscitation during air medical transport. The primary outcome was mortality at 30 days. RESULTS: A total of 501 patients were evaluated: 230 patients received plasma (plasma group) and 271 received standard-care resuscitation (standard-care group). Mortality at 30 days was significantly lower in the plasma group than in the standard-care group (23.2% vs. 33.0%; difference, -9.8 percentage points; 95% confidence interval, -18.6 to -1.0%; P=0.03). A similar treatment effect was observed across nine prespecified subgroups (heterogeneity chi-square test, 12.21; P=0.79). Kaplan-Meier curves showed an early separation of the two treatment groups that began 3 hours after randomization and persisted until 30 days after randomization (log-rank chi-square test, 5.70; P=0.02). The median prothrombin-time ratio was lower in the plasma group than in the standard-care group (1.2 [interquartile range, 1.1 to 1.4] vs. 1.3 [interquartile range, 1.1 to 1.6], P<0.001) after the patients' arrival at the trauma center. No significant differences between the two groups were noted with respect to multiorgan failure, acute lung injury-acute respiratory distress syndrome, nosocomial infections, or allergic or transfusion-related reactions. CONCLUSIONS: In injured patients at risk for hemorrhagic shock, the prehospital administration of thawed plasma was safe and resulted in lower 30-day mortality and a lower median prothrombin-time ratio than standard-care resuscitation.

Importance: Emergency medical services (EMS) commonly perform endotracheal intubation (ETI) or insertion of supraglottic airways, such as the laryngeal tube (LT), on patients with out-of-hospital cardiac arrest (OHCA). The optimal method for OHCA advanced airway management is unknown. Objective: To compare the effectiveness of a strategy of initial LT insertion vs initial ETI in adults with OHCA. Design, Setting, and Participants: Multicenter pragmatic cluster-crossover clinical trial involving EMS agencies from the Resuscitation Outcomes Consortium. The trial included 3004 adults with OHCA and anticipated need for advanced airway management who were enrolled from December 1, 2015, to November 4, 2017. The final date of follow-up was November 10, 2017. Interventions: Twenty-seven EMS agencies were randomized in 13 clusters to initial airway management strategy with LT (n = 1505 patients) or ETI (n = 1499 patients), with crossover to the alternate strategy at 3- to 5-month intervals. Main Outcomes and Measures: The primary outcome was 72-hour survival. Secondary outcomes included return of spontaneous circulation, survival to hospital discharge, favorable neurological status at hospital discharge (Modified Rankin Scale score ≤3), and key adverse events. Results: Among 3004 enrolled patients (median [interquartile range] age, 64 [53-76] years, 1829 [60.9%] men), 3000 were included in the primary analysis. Rates of initial airway success were 90.3% with LT and 51.6% with ETI. Seventy-two hour survival was 18.3% in the LT group vs 15.4% in the ETI group (adjusted difference, 2.9% [95% CI, 0.2%-5.6%]; P = .04). Secondary outcomes in the LT group vs ETI group were return of spontaneous circulation (27.9% vs 24.3%; adjusted difference, 3.6% [95% CI, 0.3%-6.8%]; P = .03); hospital survival (10.8% vs 8.1%; adjusted difference, 2.7% [95% CI, 0.6%-4.8%]; P = .01); and favorable neurological status at discharge (7.1% vs 5.0%; adjusted difference, 2.1% [95% CI, 0.3%-3.8%]; P = .02). There were no significant differences in oropharyngeal or hypopharyngeal injury (0.2% vs 0.3%), airway swelling (1.1% vs 1.0%), or pneumonia or pneumonitis (26.1% vs 22.3%). Conclusions and Relevance: Among adults with OHCA, a strategy of initial LT insertion was associated with significantly greater 72-hour survival compared with a strategy of initial ETI. These findings suggest that LT insertion may be considered as an initial airway management strategy in patients with OHCA, but limitations of the pragmatic design, practice setting, and ETI performance characteristics suggest that further research is warranted.

Importance: Traumatic brain injury (TBI) is the leading cause of death and disability due to trauma. Early administration of tranexamic acid may benefit patients with TBI. Objective: To determine whether tranexamic acid treatment initiated in the out-of-hospital setting within 2 hours of injury improves neurologic outcome in patients with moderate or severe TBI. Design, Setting, and Participants: Multicenter, double-blinded, randomized clinical trial at 20 trauma centers and 39 emergency medical services agencies in the US and Canada from May 2015 to November 2017. Eligible participants (N = 1280) included out-of-hospital patients with TBI aged 15 years or older with Glasgow Coma Scale score of 12 or less and systolic blood pressure of 90 mm Hg or higher. Interventions: Three interventions were evaluated, with treatment initiated within 2 hours of TBI: out-of-hospital tranexamic acid (1 g) bolus and in-hospital tranexamic acid (1 g) 8-hour infusion (bolus maintenance group; n = 312), out-of-hospital tranexamic acid (2 g) bolus and in-hospital placebo 8-hour infusion (bolus only group; n = 345), and out-of-hospital placebo bolus and in-hospital placebo 8-hour infusion (placebo group; n = 309). Main Outcomes and Measures: The primary outcome was favorable neurologic function at 6 months (Glasgow Outcome Scale-Extended score >4 [moderate disability or good recovery]) in the combined tranexamic acid group vs the placebo group. Asymmetric significance thresholds were set at 0.1 for benefit and 0.025 for harm. There were 18 secondary end points, of which 5 are reported in this article: 28-day mortality, 6-month Disability Rating Scale score (range, 0 [no disability] to 30 [death]), progression of intracranial hemorrhage, incidence of seizures, and incidence of thromboembolic events. Results: Among 1063 participants, a study drug was not administered to 96 randomized participants and 1 participant was excluded, resulting in 966 participants in the analysis population (mean age, 42 years; 255 [74%] male participants; mean Glasgow Coma Scale score, 8). Of these participants, 819 (84.8%) were available for primary outcome analysis at 6-month follow-up. The primary outcome occurred in 65% of patients in the tranexamic acid groups vs 62% in the placebo group (difference, 3.5%; [90% 1-sided confidence limit for benefit, -0.9%]; P = .16; [97.5% 1-sided confidence limit for harm, 10.2%]; P = .84). There was no statistically significant difference in 28-day mortality between the tranexamic acid groups vs the placebo group (14% vs 17%; difference, -2.9% [95% CI, -7.9% to 2.1%]; P = .26), 6-month Disability Rating Scale score (6.8 vs 7.6; difference, -0.9 [95% CI, -2.5 to 0.7]; P = .29), or progression of intracranial hemorrhage (16% vs 20%; difference, -5.4% [95% CI, -12.8% to 2.1%]; P = .16). Conclusions and Relevance: Among patients with moderate to severe TBI, out-of-hospital tranexamic acid administration within 2 hours of injury compared with placebo did not significantly improve 6-month neurologic outcome as measured by the Glasgow Outcome Scale-Extended.

Thirty-nine patients with the velo-cardio-facial syndrome are described in order to further delineate this probably common recurrent pattern congenital malformation syndrome. Frequent features include cleft palate, cardiac anomalies, typical facies, and learning disabilities. Less frequent findings include microcephaly, mental retardation, small stature, slender hands and digits, minor auricular anomalies and inguinal hernia. Ths Robin malformation sequence was found in four patients. The congenital heart anomalies most frequently involved a ventricular septal defect, with or without a right-sided aortic arch. There were four instances of familial transmission in the sample population. These included two cases of maternal transmission of the syndrome to daughters, one case of maternal transmission to a son, and one case of maternal transmission to both a son and daughter. There was no particular difference in expression between male and female patients so that even though X-linked dominant transmission is possible, the velo-cardio-facial syndrome is likely to be an autosomal dominant recurrent pattern syndrome.
STUDY DESIGN: A randomized controlled trial was conducted. OBJECTIVE: To determine the efficacy of osteopathic manipulative treatment as a complementary treatment for chronic nonspecific low back pain. SUMMARY OF BACKGROUND DATA: Osteopathic manipulative treatment may be useful for acute or subacute low back pain. However, its role in chronic low back pain is unclear. METHODS: This trial was conducted in a university-based clinic from 2000 through 2001. Of the 199 subjects who responded to recruitment procedures, 91 met the eligibility criteria. They were randomized, with 82 patients completing the 1-month follow-up evaluation, 71 completing the 3-month evaluation, and 66 completing the 6-month evaluation. The subjects were randomized to osteopathic manipulative treatment, sham manipulation, or a no-intervention control group, and they were allowed to continue their usual care for low back pain. The main outcomes included the SF-36 Health Survey, a 10-cm visual analog scale for overall back pain, the Roland-Morris Disability Questionnaire, lost work or school days because of back pain, and satisfaction with back care. RESULTS: As compared with the no-intervention control subjects, the patients who received osteopathic manipulative treatment reported greater improvements in back pain, greater satisfaction with back care throughout the trial, better physical functioning and mental health at 1 month, and fewer cotreatments at 6 months. The subjects who received sham manipulation also reported greater improvements in back pain and physical functioning and greater satisfaction than the no-intervention control subjects. There were no significant benefits with osteopathic manipulative treatment, as compared with sham manipulation. CONCLUSIONS: Osteopathic manipulative treatment and sham manipulation both appear to provide some benefits when used in addition to usual care for the treatment of chronic nonspecific low back pain. It remains unclear whether the benefits of osteopathic manipulative treatment can be attributed to the manipulative techniques themselves or whether they are related to other aspects of osteopathic manipulative treatment, such as range of motion activities or time spent interacting with patients, which may represent placebo effects.
The clinical practice guideline is based on a systematic review of published studies on the treatment of distal radius fractures in adults. None of the 29 recommendations made by the work group was graded as strong; most are graded as inconclusive or consensus; seven are graded as weak. The remaining five moderate-strength recommendations include surgical fixation, rather than cast fixation, for fractures with postreduction radial shortening >3 mm, dorsal tilt >10 degrees , or intra-articular displacement or step-off >2 mm; use of rigid immobilization rather than removable splints for nonsurgical treatment; making a postreduction true lateral radiograph of the carpus to assess dorsal radial ulnar joint alignment; beginning early wrist motion following stable fixation; and recommending adjuvant treatment with vitamin C to prevent disproportionate pain.
IMPORTANCE: Colorectal cancer (CRC) screening saves lives, but participation rates are low among underserved populations. Knowledge on effective approaches for screening the underserved, including best test type to offer, is limited. OBJECTIVE: To determine (1) if organized mailed outreach boosts CRC screening compared with usual care and (2) if FIT is superior to colonoscopy outreach for CRC screening participation in an underserved population. DESIGN, SETTING, AND PARTICIPANTS: We identified uninsured patients, not up to date with CRC screening, age 54 to 64 years, served by the John Peter Smith Health Network, Fort Worth and Tarrant County, Texas, a safety net health system. INTERVENTIONS: Patients were assigned randomly to 1 of 3 groups. One group was assigned to fecal immunochemical test (FIT) outreach, consisting of mailed invitation to use and return an enclosed no-cost FIT (n = 1593). A second was assigned to colonoscopy outreach, consisting of mailed invitation to schedule a no-cost colonoscopy (n = 479). The third group was assigned to usual care, consisting of opportunistic primary care visit–based screening (n = 3898). In addition, FIT and colonoscopy outreach groups received telephone follow-up to promote test completion. MAIN OUTCOME MEASURES: Screening participation in any CRC test within 1 year after randomization. RESULTS: Mean patient age was 59 years; 64% of patients were women. The sample was 41% white, 24% black, 29% Hispanic, and 7% other race/ethnicity. Screening participation was significantly higher for both FIT (40.7%) and colonoscopy outreach (24.6%) than for usual care (12.1%) (P < .001 for both comparisons with usual care). Screening was significantly higher for FIT than for colonoscopy outreach (P < .001). In stratified analyses, screening was higher for FIT and colonoscopy outreach than for usual care, and higher for FIT than for colonoscopy outreach among whites, blacks, and Hispanics (P < .005 for all comparisons). Rates of CRC identification and advanced adenoma detection were 0.4% and 0.8% for FIT outreach, 0.4% and 1.3% for colonoscopy outreach, and 0.2% and 0.4% for usual care, respectively (P < .05 for colonoscopy vs usual care advanced adenoma comparison; P > .05 for all other comparisons). Eleven of 60 patients with abnormal FIT results did not complete colonoscopy. CONCLUSIONS AND REVELANCE: Among underserved patients whose CRC screening was not up to date, mailed outreach invitations resulted in markedly higher CRC screening compared with usual care. Outreach was more effective with FIT than with colonoscopy invitation. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01191411.
AIMS: Peak oxygen uptake (VO(2)) is diminished in patients with heart failure with preserved ejection fraction (HFpEF) suggesting impaired cardiac reserve. To test this hypothesis, we assessed the haemodynamic response to exercise in HFpEF patients. METHODS AND RESULTS: Eleven HFpEF patients (73 ± 7 years, 7 females/4 males) and 13 healthy controls (70 ± 4 years, 6 females/7 males) were studied during submaximal and maximal exercise. The cardiac output (Q(c), acetylene rebreathing) response to exercise was determined from linear regression of Q(c) and VO(2) (Douglas bags) at rest, ∼30% and ∼60% of peak VO(2), and maximal exercise. Peak VO(2) was lower in HFpEF patients than in controls (13.7 ± 3.4 vs. 21.6 ± 3.6 mL/kg/min; P < 0.001), while indices of cardiac reserve were not statistically different: peak cardiac power output [CPO = Q(c) × mean arterial pressure (MAP); HFpEF 1790 ± 509 vs. controls 2119 ± 581 L/mmHg/min; P = 0.20]; peak stroke work [SW = stroke volume (SV) × MAP; HFpEF 13 429 ± 2269 vs. controls 13 200 ± 3610 mL/mmHg; P = 0.80]. The ΔQ(c)/ΔVO(2) slope was abnormally elevated in HFpEF patients vs. controls (11.2 ±3.6 vs. 8.3 ± 1.5; P = 0.015). CONCLUSION: Contrary to our hypothesis, cardiac reserve is not significantly impaired in well-compensated outpatients with HFpEF. The abnormal haemodynamic response to exercise (decreased peak VO(2), increased ΔQ(c)/ΔVO(2) slope) is similar to that observed in patients with mitochondrial myopathies, suggesting an element of impaired skeletal muscle oxidative metabolism. This impairment may limit functional capacity by two mechanisms: (i) premature skeletal muscle fatigue and (ii) metabolic signals to increase the cardiac output response to exercise which may be poorly tolerated by a left ventricle with impaired diastolic function.
OBJECTIVE: The aim of this study was to determine whether prehospital blood products reduce 30-day mortality in patients at risk for hemorrhagic shock compared with crystalloid only resuscitation. SUMMARY OF BACKGROUND DATA: Hemorrhage is the primary cause of preventable death after injury. Large volume crystalloid resuscitation can be deleterious. The benefits of prehospital packed red blood cells (PRBCs), plasma, or transfusion of both products among trauma patients is unknown compared with crystalloid. METHODS: Secondary analysis of the multicenter PAMPer trial was performed on hypotensive injured patients from the scene. The trial randomized 27 helicopter bases to prehospital plasma or standard resuscitation. Standard resuscitation at the sites was equally divided between crystalloid and crystalloid + PRBC. This led to 4 prehospital resuscitation groups: crystalloid only; PRBC; plasma; and PRBC+plasma. Cox regression determined the association between resuscitation groups and risk-adjusted 30-day mortality. The dose effect of resuscitation fluids was also explored. RESULTS: Four hundred seven patients were included. PRBC+plasma had the greatest benefit [hazard ratio (HR) 0.38; 95% confidence interval (95% CI) 0.26-0.55, P < 0.001], followed by plasma (HR 0.57; 95% CI 0.36-0.91, P = 0.017) and PRBC (HR 0.68; 95% CI 0.49-0.95, P = 0.025) versus crystalloid only. Mortality was lower per-unit of PRBC (HR 0.69; 95% CI 0.52-0.92, p = 0.009) and plasma (HR 0.68; 95% CI 0.54-0.88, P = 0.003). Crystalloid volume was associated with increased mortality among patients receiving blood products (HR 1.65; 95% CI 1.17-2.32, P = 0.004). CONCLUSION: Patients receiving prehospital PRBC+plasma had the greatest mortality benefit. Crystalloid only had the worst survival. Patients with hemorrhagic shock should receive prehospital blood products when available, preferably PRBC+plasma. Prehospital whole blood may be ideal in this population.
Kienbock's disease, or osteonecrosis of the lunate, can lead to chronic, debilitating wrist pain. Etiologic factors include vascular and skeletal variations combined with trauma or repetitive loading. In stage I Kienbock's disease, plain radiographs appear normal, and bone scintigraphy or magnetic resonance imaging is required for diagnosis. Initial treatment is nonoperative. In stage II, sclerosis of the lunate, compression fracture, and/or early collapse of the radial border of the lunate may appear. In stage IIIA, there is more severe lunate collapse. Because the remainder of the carpus is still uninvolved, treatment in stages II and IIIA involves attempts at revascularization of the lunate-either directly (with vascularized bone grafting) or indirectly (by unloading the lunate). Radial shortening in wrists with negative ulnar variance and capitate shortening or radial-wedge osteotomy in wrists with neutral or positive ulnar variance can be performed alone or with vascularized bone grafting. In stage IIIB, palmar rotation of the scaphoid and proximal migration of the capitate occur, and treatment addresses the carpal collapse. Surgical options include scaphotrapeziotrapezoid or scaphocapitate arthrodesis to correct scaphoid hyperflexion. In stage IV, degenerative changes are present at the midcarpal joint, the radiocarpal joint, or both. Treatment options include proximal-row carpectomy and wrist arthrodesis.
OBJECTIVES: Historically, mechanically unstable fractures of the distal femur have been difficult to treat. Problems such as varus collapse, malunion, and nonunion frequently resulted before fixed-angle plates and indirect reduction techniques were popularized. More recently, the Less Invasive Stabilization System, or LISS (Synthes, Paoli, PA), has been designed to combine these 2 approaches with the intended goals of achieving adequate stable fixation and early healing. Early clinical results for the femoral Less Invasive Stabilization System have been promising. The purpose of this study is to evaluate the clinical results of patients with high energy, mechanically unstable fractures of the distal femur treated with the Less Invasive Stabilization System. DESIGN: Retrospective analysis of a treatment protocol, consecutive patient series. SETTING: Busy level II trauma center. PATIENTS /PARTICIPANTS: Twenty-six patients with 27 high-energy AO/OTA types A2, A3, C2, and C3 fractures of the distal femur. INTERVENTION: Treatment with indirect fracture reduction and internal distal femoral fixation using the Less Invasive Stabilization System. MAIN OUTCOME MEASUREMENTS: Clinical and radiographic assessment. RESULTS: Twenty-one patients with 22 fractures were available for evaluation at an average 19 months postinjury (range 12-35 months). The mechanism of injury included 12 motor vehicle collisions, 4 high falls, 5 motorcycle crashes, and 1 bicyclist struck by a car. Twenty patients had associated injuries. Six fractures were open. All fractures were comminuted; according to the AO/OTA fracture classification there were 4 A2, 3 A3, 12 C2, and 3 C3 fractures. All fractures healed without secondary surgeries at a mean of 13 weeks (range 7-16 weeks). There were no cases of failed fixation, implant breakage, or infection. Average joint line orientation relative to the femoral shaft axis (valgus) measured 99 degrees on postoperative radiographs and 99 degrees on final radiographs. A comparison of postoperative to healed final radiographs for each femur demonstrated no case with greater than a 3 degrees difference in either varus or valgus. Complications included 1 mal-union where the fracture was fixed in 8 degrees of valgus and 2 cases of external rotation between 10 degrees and 15 degrees. Painful hardware occurred in 4 patients, of which 3 underwent implant removal. The average knee range of motion was 5 degrees to 114 degrees. CONCLUSIONS: The Less Invasive Stabilization System allows for stable fixation and facilitates early healing in mechanically unstable high-energy fractures of the distal femur. There were no patients with fixation failure, varus collapse, or nonunion in this "at-risk" population. This treatment safely allows for immediate postoperative initiation of joint mobility and the progression of weight bearing with early radiographic signs of healing.
OBJECTIVE: Results of surgical treatment for clavicle injuries using standard approaches have shown relatively high complication rates including loss of fixation, persistent nonunion, implant related problems, and the need for subsequent surgeries are common. The purpose of this study is to evaluate the clinical results of patients treated for clavicle fractures and painful clavicular nonunions with anterior-inferior plating using a 3.5 mm plate. DESIGN: Consecutive clinical series. SETTING: 3 tertiary care academic trauma centers (Level 1 and 2). PATIENTS: Eighty consecutive patients with a middle-third fracture or painful nonunion of the clavicle. INTERVENTION: Open reduction and internal fixation using an anterior-inferior plating technique with a precontoured 3.5 mm plate and lag screw(s). Nonunions received autologous bone grafts. MAIN OUTCOME MEASUREMENTS: Patients were evaluated using physical and radiographic examination, the American Shoulder and Elbow Surgeons Shoulder Assessment (ASES), and the Short Form-36 (SF-36) outcomes questionnaire. RESULTS: Fifty-eight patients had sufficient records and follow-up of at least 24 months (mean 49 months). Clinical and radiographic union was present at a mean of 9.5 weeks for patients treated for acute fracture and 10.5 weeks those treated for nonunion. Complications included 1 failure of fixation, 1 nonunion, and 3 infections. Two patients underwent implant removal for bothersome hardware. Shoulder motion was good or excellent in all patients except those with neurologic injury. Functional results (ASES and SF-36) were good or excellent for the vast majority of patients, except those with neurologic injury. CONCLUSIONS: Anterior-inferior plating of acute middle-third fractures of the clavicle and clavicular nonunions using a plate and lag screws typically results in early healing, few complications and an excellent return of function. Advantages of this technique include stable bony fixation with instrumentation directed away from potentially dangerous infraclavicular structures and a minimal incidence of implant prominence problems.
The promotion of self-care and the prevention of burnout among nurses is a public health priority. Evidence supports the efficacy of yoga to improve physical and mental health outcomes, but few studies have examined the influence of yoga on nurse-specific outcomes. The purpose of this pilot-level randomized controlled trial was to examine the efficacy of yoga to improve self-care and reduce burnout among nurses. Compared with controls (n = 20), yoga participants (n = 20) reported significantly higher self-care as well as less emotional exhaustion and depersonalization upon completion of an 8-week yoga intervention. Although the control group demonstrated no change throughout the course of the study, the yoga group showed a significant improvement in scores from pre- to post-intervention for self-care (p < .001), mindfulness (p = .028), emotional exhaustion (p = .008), and depersonalization (p = .007) outcomes. Implications for practice are discussed.
Late loss of initially integrated endosseous implants has generally been attributed to implant overload often the result of inappropriate prosthesis design. Implant placement is rarely contraindicated by preexisting systemic diseases, and no instances of medication-induced implant failure have been reported in the literature. This paper reports a case in which a patient lost five endosseous implants that had successfully osseointegrated and had been restored with a lower hybrid prosthesis approximately 6 months after diphosphonate therapy for osteoporosis was started.
OBJECTIVE: The purpose of this study is to evaluate clinical results and outcomes of a strict cohort of high-energy injuries of the metaphyseal distal tibia with minimal or no intraarticular involvement treated using the minimally invasive plating concept. SETTING: Level II trauma center. DESIGN: Retrospective analysis of a consecutive case series with limb-specific and whole-person outcomes measures. INTERVENTION: Minimally invasive medial plating for high-energy metaphyseal fractures of the distal tibia with little or no intraarticular involvement. MAIN OUTCOME MEASUREMENT: Clinical and radiographic results were assessed at a minimum of 1 year, and outcomes measures were applied at final follow-up at a minimum of 2 years. Limbs were assessed with the American Orthopaedic Foot and Ankle Surgeons (AOFAS) ankle-hindfoot instrument and the method of Olerud and Molander. Patient outcomes were evaluated with the Short Form-36 (SF-36) and the Musculoskeletal Functional Assessment (MFA). RESULTS: Twenty-six patients were followed until healed at an average of 36 months (12-56 months). Mean fracture healing time was 35 weeks (12-112 weeks) with acceptable alignment restored (angulation<or=5 degrees or shortening<or=1 cm) in all but 1 case. Two patients (7%) had loss of fixation and 9 (35%) underwent secondary surgeries to achieve union. Risk factors for healing problems included high grades of fracture comminution, bone loss, and high-grade open injuries (P<0.05). SF-36 outcomes scores in 21 patients at >2 years were comparable to normative data of patients with uninjured limbs, whereas MFA results showed functional deficits in 4 of 10 subsections. CONCLUSIONS: Minimally invasive medial plating will restore limb alignment and yield successful clinical outcomes for high-energy metaphyseal fractures of the distal tibia. Despite the significant reoperation rate and prolonged time to union, most patients can expect a predictable return of function. Strong consideration should be given to adjunctive measures in at-risk patients, including those with highly comminuted fracture patterns, bone loss, or Type II or III open fractures.
The proper treatment of Kienböck's disease, a disorder that displays slow progression with eventual collapse of the lunate and alteration of the surrounding carpal architecture, requires an understanding of its aetiology and natural history. A reproducible classification system assists the surgeon in making appropriate treatment choices. In this discussion, we review the history and rationale for the four-stage step-wise classification system, along with our current treatment algorithm. We also discuss emerging classification systems and speculate on future directions in treatment and research.

Of 43 patients who sustained blunt trauma resulting in a major renal laceration with a devitalized fragment 27 had coexisting intraperitoneal and renal injuries for which emergency celiotomy and repair of the nonurological trauma were done. Management of the renal injuries consisted of simultaneous renal exploration with 23% urological morbidity in 13 cases or expectant management with 85% urological morbidity in 14 cases. In this latter patient population infected urinomas and perinephric abscesses seeded from coexisting enteric or pancreatic injuries were the most common complication (57%). The remaining 16 of the 43 patients sustained renal lacerations without associated intraperitoneal injuries and all were managed expectantly with 38% urological morbidity. These findings suggest that renal exploration and surgical repair significantly improve the prognosis only in patients with simultaneous intraperitoneal and renal injuries (p < 0.01).
OBJECTIVE: Management of vertical femoral neck fractures in young adults has been a challenging clinical problem, resulting in mixed clinical outcomes. A thorough understanding of the fracture morphology for this injury pattern is lacking, which may contribute to frequent failures of treatment. This study is designed to produce a detailed description of the pathoanatomy of these fractures, which may ultimately be helpful in developing more informed reduction and fixation strategies. DESIGN: Retrospective study of patient records, plain radiographs, and computed tomography scans to determine the morphology the Pauwels III femoral neck fractures (coronal angle >50 degrees) in young adults. SETTING: Two level I and 1 level II regional trauma centers. PATIENTS: All patients 18-49 years of age with a surgically repaired, high-energy high shear angle (>50 degrees) femoral neck fracture from January 1, 2007, to December 31, 2010. METHODS: One hundred thirty-six adult patients younger than 50 years were identified with a femoral neck fracture in the study period, of whom 33 met all study criteria. We evaluated plain radiography and computed tomography data including fracture orientation, comminution, deformity, characteristics of the inferomedial fracture spike, and the associated inferomedial calcar's cortical buttress. RESULTS: The vertical (coronal) fracture averaged 60 degrees and axial fracture obliquity averaged 24 degrees with relative deficiency of the posterior neck on the head-neck fragment. Major femoral neck comminution (>1.5 cm in any dimension) was identified in 96% of cases, mostly located in the inferior (94%) and posterior (82%) quadrants. The apical fracture spike of the head segment was found to be in line (within 10 degrees) of the neck-shaft axis on the proximal femur 63% of the time. Deformity in external rotation averaged 44 degrees (range, 10-68 degrees) and shortening of the femur averaged 1.8 cm (range, 0.9-4.4 cm). CONCLUSIONS: This study investigated the fracture morphology of isolated, high shear angle femoral neck fractures in young adults, which may ultimately lead to improved operative reduction and fixation tactics. Given this injury's characteristic findings, including fracture orientation, deformity, and comminution, surgeons should be cognizant of this pattern's innate instability and potential for treatment failure with typical implant constructs.
