A total of eight patients underwent prosthetic replacement, 3 as a primary treatment and 5 as a salvage procedure after failure of internal fixation. selleckchem Five patients developed a deep infection (62.5%).We observed 10 non-union (53%) in 19 patients treated with osteosynthesis. Overall amputation rate of the entire series was 18%. Authors propose a flowchart of treatment for femoral fractures.

Intramedullary nailing is the treatment of choice in postradiation diaphyseal fractures of long bones, prosthetic replacement in meta-epiphyseal fracture site. Free vascularized grafts remain a valid salvage solution after failure of internal fixation.

Surgery is usually suggested to treat massive haemothorax (MHT). The MHT criteria are based on penetrating trauma observations in military scenarios; the need for surgery in blunt trauma patients remains questionable. This study aimed to determine the characteristics of blunt trauma patients with MHT who required surgery.

Patients who presented to the emergency department (ED) with traumatic haemothorax or pneumothorax, heart and lung injuries, and thoracic blood vessel injuries from Jan 1, 2014, to Dec 31, 2018, were reviewed. The inclusion criterion was a chest tube drainage amount that met the MHT criteria. Therapeutic operations were defined as those involving surgical haemostasis; otherwise, operations were considered non-therapeutic. The non-therapeutic operation group included the patients who received nonoperative management. The characteristics of the therapeutic and non-therapeutic operation groups were compared.

Forty-four patients were enroled in the study. Six patients received conservative treatment and were discharged uneventfully. Eleven patients underwent non-therapeutic operations. The patients with surgical bleeding had a high pulse rate (125.0 (111.0, 135.0) vs. 116.0 (84.0, 121.0) bpm, p=0.013); low systolic blood pressure (SBP) after resuscitation (106.0 (84.0, 127.0) vs. 121.0 (116.0, 134.0) mmHg, p=0.040); low pH (7.2 (7.2, 7.3) vs. 7.4 (7.3, 7.4), p=0.002); and low bicarbonate (17.8 (14.6, 21.5) vs. 21.4 (17.0, 21.5) mEq/L, p=0.038), low base excess (-9.1 (-13.4, -4.5) vs. -3.8 (-10.1, -0.7), p=0.028), and high lactate (5.7 (3.3, 7.8) vs. 1.8 (1.7, 2.8) mmol/L, p=0.002) levels.

Conservative treatment could be performed selectively in patients with MHT. Lactate could be a predictor of the need for surgical intervention in blunt trauma patients with MHT.

While few studies analysed the diagnostic validity of preoperative radiographs in distinguishing between Vancouver type B1 and B2 periprosthetic femoral fractures (PFFs), no investigation has been conducted to assess the degree of diagnostic validity of preoperative radiographs in identifying the fracture course and planning the most appropriate treatment. We analysed the diagnostic validity of radiographs in detecting the fracture course and stem stability in Vancouver type B PFFs.

Vancouver type B PFFs with different fracture courses were randomly performed in 36 dried cadaveric femurs in which a femoral broach had previously been implanted. Radiographic images, taken in the coronal and sagittal views, were analysed by 5 orthopaedic surgeons and 2 radiologists who were asked to reproduce the fracture course and to evaluate stem stability. A scoring system was used to determine the injured femoral cortex correctly identified by the examiners.

The identification of the fracture course was scored as poorse is hidden by the femoral stem. In cementless stems the diagnostic validity of radiographs in diagnosing between Vancouver type B1 and B2 seems to be lower than that reported for cemented stems.
In type B PFFs preoperative radiographs show a reduced diagnostic validity in identifying the fracture course and, hence, in planning a correct treatment. Potentially unstable vertical fractures involving an emidiaphysis are likely to be poorly diagnosed since most of the fracture course is hidden by the femoral stem. In cementless stems the diagnostic validity of radiographs in diagnosing between Vancouver type B1 and B2 seems to be lower than that reported for cemented stems.
Although several risk stratification models have been developed to predict hip fracture mortality, efforts are still being placed in this area. Our aim is to (1) construct a risk prediction model for long-term mortality after hip fracture utilizing the RSF method and (2) to evaluate the changing effects over time of individual pre- and post-treatment variables on predicting mortality.

1330 hip fracture surgical patients were included. Forty-five admission and in-hospital variables were analyzed as potential predictors of all-cause mortality. A random survival forest (RSF) algorithm was applied in predictors identification. Cox regression models were then constructed. Sensitivity analyses and internal validation were performed to assess the performance of each model. C statistics were calculated and model calibrations were further assessed.

Our machine-learning RSF algorithm achieved a c statistic of 0.83 for 30-day prediction and 0.75 for 1-year mortality. Additionally, a COX model was also constructed by using the variables selected by RSF, c statistics were shown as 0.75 and 0.72 when applying in 2-year and 4-year mortality prediction. The presence of post-operative complications remained as the strongest risk factor for both short- and long-term mortality. Variables including fracture location, high serum creatinine, age, hypertension, anemia, ASA, hypoproteinemia, abnormal BUN, and RDW became more important as the length of follow-up increased.

The RSF machine-learning algorithm represents a novel approach to identify important risk factors and a risk stratification models for patients undergoing hip fracture surgery is built through this approach to identify those at high risk of long-term mortality.
