There are various types of intertrochanteric fractures that are unstable pertrochanteric fractures of the hip. The aim of this study was to develop a systematic and comprehensive classification of intertrochanteric fractures. ⋯ We believe our new classification is a useful communication tool for medical professionals in the diagnosis of fractures.

Partial weight bearing is part of treatment schemes in orthopedic surgery and traumatology. The aim of the present study was to explore to what degree ground reaction forces during partial weight bearing of the lower leg are related to given instructions and to tibia deformation. ⋯ These findings result in the following clinical "lessons learned": 1. GRF is a good reflection of loading-induced deformation of the tibia. 2. GRFs are hard to control by subjects/patients. 3. The expectation that forefoot-loading results in larger tibia deformation could not be confirmed in our study. 4. When aiming at a reduction in tibia deformation, rear-foot loading is more preferable than forefoot loading.

The reported prognosis for recovery after peripheral nerve injury is remarkably poor. Deficits may persist for years, resulting in significant functional disability. Both corticosteroids and Erythropoietin have been investigated as neuroprotective agents; however, their efficacy in total hip and knee arthroplasty is not known. The purpose of this study was to evaluate the effect of systemically-administered Erythropoietin and tapered oral corticosteroids on the recovery of postoperative nerve palsies in the setting of total hip and knee arthroplasty. ⋯ Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Observational Study
Incidence rate of mild traumatic brain injury among patients who have suffered from an isolated limb fracture: Upper limb fracture patients are more at risk.
This study compares the incidence rate of mild traumatic brain injury (mild TBI) detected at follow-up visits (retrospective diagnosis) in patients suffering from an isolated limb trauma, with the incidence rate held by the hospital records (prospective diagnosis) of the sampled cohort. This study also seeks to determine which types of fractures present with the highest incidence of mild TBI. ⋯ Results suggest an important concomitance of mild TBI among orthopaedic trauma patients, the majority of which go undetected during acute care. Patients treated for an upper limb fracture are particularly at risk of sustaining concomitant mild TBI.

Comminuted proximal ulna fractures are rare and reconstruction of these fractures is discussed controversially. The aim of this study was to test three currently available plate devices in a standardized comminuted four-part fracture model created in proximal ulna sawbones. ⋯ The locked angle plate system showed the highest stability in 90° of elbow flexion. Each implant was more stable in 30° flexion than in 90° flexion. Testing of the anterior stability of the elbow did not show any differences between the different implants. Because of the superior stability of this device, we conclude that locked angle plating should be preferred for reconstruction of monteggia like complex proximal ulna fractures.
