A fracture of the tuberosity is associated with 16% of glenohumeral dislocations. Extension of the fracture into the humeral neck can occur during closed manipulation, leading some to suggest that all such injures should be managed under general anaesthesia in the operating theatre. The purpose of this study was to establish the safety of reduction of glenohumeral dislocations with tuberosity fractures in the emergency department (ED). ⋯ Closed reduction of glenohumeral dislocations with associated tuberosity fractures in the ED is safe, with a rate of iatrogenic fracture of 1%. These injuries should be managed by those with appropriate experience only after two adequate radiographic views. In cases where there is ambiguity over the integrity of the humeral neck, reduction should be delayed until multiplanar CT imaging has been obtained.

Patient outcomes after intertrochanteric fracture fixation is the subject of a large body of published and ongoing clinical research. Fracture reduction and stable fixation are a pre-requisite for achieving optimal results. However, reporting on the quality of postoperative reduction and fixation, has been inconsistent in the literature on intertrochanteric fractures. The purpose of this study was to examine the quality and consistency of reporting of immediate postoperative reduction and fixation in clinical outcome studies of intertrochanteric fracture fixation. ⋯ Despite its recognized influence on outcomes of intertrochanteric fractures, leading peer-reviewed journals do not uniformly report on the immediate postoperative assessment of the quality of reduction and fixation. However, reporting has improved over the past five years. Standardized quantitative metrics will need to be reported in the future to allow meaningful comparisons between studies and accurate assessment of intertrochanteric fracture outcome.

Ultrasound has been commonly employed for depicting the morphology of the lesions in patients with radial nerve neuropathy, including entrapment, tumor, trauma, and iatrogenic injury. However, few studies have evaluated the efficacy of ultrasound for visualizing radial nerve lesions with coexistent plate fixation of humeral shaft fractures. This study aimed to address this special clinical issue. ⋯ Ultrasonography can accurately depict radial nerve lesions with coexistent plate fixation of humeral shaft fractures. It provides a basis for determining the extent of nerve damage in all patients except those with the lesion radial nerve in continuity, which is conducive to making treatment decisions as early as possible.

Single nucleotide variants (SNVs) represent important genetic risk factors for susceptibility to posttraumatic sepsis and a potential target for immunotherapy. We aimed to evaluate the association between 8 different SNVs within tumor necrosis factor alpha (TNFA), lymphotoxin alpha (LTA) and Toll-like receptor (TLR2 and TLR4) genes and the risk of posttraumatic sepsis. ⋯ Carriage of the G allele of the TNFA rs1800629 gene variant and T allele-carriage of the TLR4 rs4986791 genetic variant confer significant risk of posttraumatic sepsis. TLR4 gene variants (rs4986790 and rs4986791) has been labelled as disease causing.

Infected post-traumatic distal femur defects remain a therapeutic challenge. Non-biological reconstruction offers an option for avoiding complex biological knee arthrodesis procedures. The CompressⓇ implant is an alternative to the traditional distal femur stemmed megaprosthesis. The aim of this study is to analyse the first patients treated with a distal femur CompressⓇ prosthesis to manage massive infected post-traumatic defects of the distal femur with joint involvement. ⋯ Non-biological reconstruction of the distal femur with the CompressⓇ implant is a valid option in selected patients with massive infected defects with joint involvement. Survivorship was high, with all loosening occurring in the first months after surgery-representing a failure in the osseointegration of the implant.
