Pauwels classification, which categorizes types of femoral neck fractures, cannot fully reflect the three-dimensional characteristics of this injury. The purpose of our study was to determine the morphological characteristics of Pauwels III fractures through computed tomography image analysis and summarize the relevant biomechanical characteristics of different morphological fractures. ⋯ Biomechanical differences across the three subtypes of Pauwels III femoral neck fractures could increase our understanding of the biomechanical characteristics that underlie the Pauwels type III femoral neck fractures (such as, three-dimensional morphology and the stress distribution of bone and implant) that have been associated with high failure rates.

The Internet is a resource that patients can use to learn about their injuries, treatment options, and surgeon. Previously, it was demonstrated that orthopaedic trauma patients are unlikely to use a reliable, provided source. It is unknown however, if patients are seeking information from elsewhere. The purpose of this study was to determine if orthopaedic trauma patients utilize the Internet and what websites are utilized. Our hypothesis was that the majority of patients use the Internet and when they do, are unlikely to use a reliable source. ⋯ Prognostic, Level II.

Study outcomes, predictors of mortality, and effects of procedural interventions on patients following traumatic inhalational airway injury. ⋯ Active smoking was associated with decreased odds of in-hospital mortality, while presence of pre-existing medical comorbidities and history of alcohol use disorder was associated with increased odds of in-hospital mortality. Procedural intervention had little to no association with in-hospital mortality but did affect overall hospital and ICU LOS.

Hip fractures in the elderly impact negatively on functional dependence, and carry great social costs and morbidity. We assessed the decline in muscle mass and functional outcomes following hip fracture surgery . ⋯ Geriatric hip fracture patients may experience a significant loss of muscle mass, associated with impaired functional recovery 1 year after hip surgery, highlighting a potential treatment target of maintaining muscle mass to improve prognosis in these patients.

Hydroxyapatite (HA) augments are frequently used in orthopedic surgery. However, the effectiveness of HA augments on the treatment of intertrochanteric femoral fractures remains unknown. This study aimed to investigate whether the use of HA tubes affects the intraoperative insertion torque of the lag screw during intertrochanteric femoral fracture surgery. ⋯ Our results strongly suggest that the use of HA tubes increases the intraoperative lag screw insertion torque/BMD ratio and may improve the lag screw fixation by strengthening the bone/metal thread interface in the treatment of intertrochanteric femoral fractures.
