Displaced humeral shaft fractures: Assessment of fracture union and complications following dual plate fixation using an anterior approach.
The humeral bone is subject to torsional forces. In case of displaced shaft fractures, internal fixation remains the standard of care. This retrospective two-center study assessed the fracture union rate and complications after dual 3.5 mm locking compression plate (LCP) fixation using an anterolateral approach. ⋯ The simplicity of the technique described here, and the short operative time, may help explain the low infection rate. Dual plate fixation makes it possible to use more screws and allows nerve exploration and decompression in case of preoperative nerve palsy. Dual plate fixation to treat humeral shaft fractures is a simple and reliable technique.

Multicenter Study Comparative Study
Influencing factors and early predictive model of acute stress disorder in traumatic patients: A clinical comparative cohort study.
To analyze the main influencing factors of ASD (Acute Stress Disorder) in inpatients, and provide some evidence for early clinical identification and intervention of ASD. ⋯ Based on the different risk factors, an early effective model could be built for ASD prediction in both traumatic and nontraumatic patients.

Periprosthetic fracture around total knee arthroplasty: What are the advantages of minimal-invasive surgery?
Periprosthetic femur fractures after total knee arthroplasty in older adults are mostly treated by internal fixation. Members of the GETRAUM (French Orthopedic Trauma Society) sought to compare two surgical techniques - conventional open surgery and minimally invasive surgery - with the aim of analyzing the patients' functional recovery. We hypothesized that a minimally invasive technique would produce better early functional outcomes with recovery of independence. ⋯ Our hypothesis was confirmed, as there was a difference between techniques that impacted functional recovery and independence, but only in the early postoperative phase. A minimally invasive technique appears to be beneficial in the short term for distal femur fractures after total knee arthroplasty but must be evaluated in a comparative and prospective study to fully confirm its reliability.

Although the diagnostic criteria for atypical femoral fracture (AFF) exclude periprosthetic fractures, reports of periprosthetic femoral fractures with characteristics of AFF are rapidly increasing. In this study, we investigated the frequency and pathogenesis of periprosthetic AFF associated with total knee arthroplasty (TKA) based on a theory of AFF subtypes that divides AFFs into two main types: fragility stress fractures of the bowed femoral shaft in the mid-shaft and "typical" subtrochanteric AFFs due to suppression of bone turnover (e.g., by bisphosphonates). ⋯ Orthopedic surgeons should recognize the presence of TKA-associated periprosthetic AFF caused by various factors including specific drugs, bowing deformity, and lower limb alignment. X-rays of the full-length femurs should be checked regularly after TKA, especially in patients with bowed femurs or long-term exposure to specific drugs.

Determinants of non-union after standard plate fixation for combined radial and ulnar fractures in adults.
Treatment of mid-shaft fractures of both forearm bones in adults typically consists of individual plate fixation of each bone according to AO principles. The primary objective of this multicentre retrospective study was to identify predictive and prognostic factors of failed bone union after internal fixation with a standard plate in adults. 130 mid-shaft fractures of both forearms occurred in 92 men and 38 women, who had a mean age of 35.1 years were reviewed; 42 were open: 31 were Gustilo type I, 10 were type II and 1 was type III. All patients underwent ORIF using a direct approach over the supinator crest for the ulnar fracture and using an anterior approach at the level of the radial fracture by dynamic compression plate in 90 cases and a limited-contact dynamic compression plate in 40 cases, all with 3.5 mm diameter screws. ⋯ The type of plate used and the number of screws placed on either side of the fracture site had no effect on union. This patient series had a similar non-union rate to the one reported in other published studies, likely because the technical rules were followed. A lack of statistical power probably prevented us from identifying prognostic factors for bone union.
