BACKGROUND Homeless individuals suffer a greater burden of health problems than the general population. This study aimed to describe the epidemiology of physical trauma among homeless patients presenting to an urban major trauma center and to ascertain any differences in the nature, injury severity and outcomes among homeless compared to domiciled patients. METHODS A retrospective matched cohort study that included adults who met inclusion criteria for The Alfred Hospital Trauma Registry between 01 July 2010 and 31 March 2017 was conducted. Primary homelessness was identified using the International Statistical Classification of Diseases, 10th Revision Coding Z59.0 and/or 'No fixed abode' address data. Homeless and domiciled patients were matched at a 12 ratio on age, sex, month and year of injury. The primary outcome variable was the Injury Severity Score (ISS). Secondary outcomes were hospital length of stay (LOS), mortality, emergency department (ED) disposition, hospital disposition, discharge processes aof assault, intentional self-harm, penetrating injury, psychiatry admissions, DAMA but lower ISS than domiciled patients. Variable definitions of homelessness and lack of standardized documentation in the medical record should be addressed to ensure these vulnerable patients are identified and linked with peripheral services. INTRODUCTION Internal fixation (IF) with cannulated screws is the most widely accepted operation method for nondisplaced femoral neck fractures (FNFs) in elderly patients. However, there were higher rate of reoperation, severe complications and poorer functional outcomes reported in these patients treated with IF. The purpose of this research is to compare the prognosis, complications, reoperation and mortality of bipolar hemiarthroplasty (HA) with IF of cannulated screws in elderly patients. METHODS All elderly patients (>75 years of age) with nondisplaced FNFs from January 2010 to December 2015 at our institution were included in this study. Patients treated with HA and IF with cannulated screws were compared. Outcome measures included the surgical complications, perioperative parameters, hip joint function, reoperation and mortality. Biocytin supplier RESULTS The blood loss of HA group (150.0 ± 55.1 mL) was statistically more than IF group (40.5 ± 15.7 mL, p = 0.001). However, the blood transfusion rate was similar between two groups (p = 0.102). At the last follow-up, there were total 14 (34.1%) severe surgical complications in the IF group, compared to 9 (10.1%) in the HA group (P = 0.001). No difference was detected between two groups with respect to the HHS and VAS at the last follow-up. Compared with the HA group, the IF group had much more reoperation in the follow up period (p = 0.001). There was no statistically differences of mortality rate between HA group (39.3%, 35/89) and IF group (34.1%, 14/41) (p=0.571). CONCLUSIONS As a treatment option for nondisplaced intracapsular FNFs in elderly patients, HA showed the merits of a less surgical complications and less reoperations, while IF demonstrated a shorter surgical time and less intraoperative blood loss. Meanwhile, there was no significant difference in the hip joint function and mortality rate in midterm follow-up. Further evaluation with a longer follow-up is recommended to strengthen these findings. BACKGROUND The literature places the occurrence of paediatric Monteggia lesions between 1.5% and 3% of all childhood elbow injuries. There are circumstances, which may make early correct diagnosis difficult. Failure to make an early correct diagnosis may have catastrophic consequences on joint range of motion in the chronic stage. The goal of this paper is to describe our three-step approach to the treatment of acute Monteggia lesions based on the stability and radiological appearance of the fracture dislocation, to give an overview of possible pitfalls and clinical and radiological signs that aid the diagnostic process. METHODS Retrospective analysis of 23 patients treated for this type of injury at our Department over a period of 6 years was performed. Treatment options were 1. Closed reduction under image intensifier followed by immobilization in over the elbow cast, 2. Open reduction and intramedullary nailing with ESIN, or 3. Open reduction and plate osteosynthesis. Average follow-up was 37 months. In our Department we aim for definitive treatment of fracture-dislocations in children within the acute setting. In the 23 acute cases, the selected procedure-reduction+casting/reduction+ESIN/reduction+plating - was performed within 2 to 16 h of arrival. 10 patients were treated with reduction+casting, 10 with reduction+ESIN and 3 with reduction+plating. RESULTS 21 patients were available for long-term follow-up. No nerve or tendon injuries or infections were observed in these cases. By managing the patients with the Three Step Method retaining the reduction was successful in all but one of our acute cases in the study period. Excellent range of motion was observed in all three groups. CONCLUSIONS The Three Step Method allows for primary definitive treatment of these lesions with low complication rates and good range of motion result. Implementing the three step method in the acute phase helps avoid catastrophic consequences on joint range of motion in the chronic stage. INTRODUCTION To establish normative data, long-term patient-reported functional outcome and health-related quality of life (HrQoL) after operative treatment of bicondylar tibial plateau fractures. Secondly, to identify risk factors associated with functional outcome and HrQoL. PATIENTS AND METHODS We performed a retrospective cohort study at two Level I trauma centers. All adult patients with AO/OTA 41-C or Schatzker V/ VI tibial plateau fractures treated between 2001 and 2016 (n = 450) by open reduction internal fixation (ORIF). The survey was completed by 214 patients (48%). Primary outcome was patient-reported functional outcome assessed with the PROMIS Physical Function (PROMIS PF). Secondary outcomes were HrQoL measured with the EuroQol 5-Dimensions 3-Levels (EQ-5D-3 L), infection rate, and total knee arthroplasty (TKA) rate. RESULTS Infection occurred in 26 cases (12%) and TKA was performed in 6 patients (3%). The median PROMIS PF scores was 49.8 (IQR;42-54). The median EQ-5D-3 L was 0.83 (IQR;0.78-1.0).
