From the last 100 to the first 100-outcome after a manufacturer change in reverse fracture arthroplasty.
If surgery is indicated for elderly patients suffering a proximal humerus fracture, reverse fracture arthroplasty became the preferred type of treatment due to its good and reliable outcomes over the last decade. Surgeons could choose from a wide range of implants and up to now there was no evaluation, if a change of the manufacturer affects patients` outcome. ⋯ A manufacturer change on the fly is possible without negative consequences for patients` outcome. Expertise of the whole OR-team as well as standardized training with the new implant seems to be a more important factor than a specific type of implant.

Risk factors of avascular femoral head necrosis after a pediatric femoral neck fracture: a 15-year follow up and an adjustment to the Delbet classification.
Pediatric femoral neck fractures (PFNF) are rare but associated with a high rate of serious complications such as avascular femoral head necrosis (AVN). Major risk factors and prognostic tools for an AVN are still unclear. As AVN is a devastating complication, this study aims to evaluate the predictors for AVN following a PFNF. ⋯ Neurologically impaired patients are prone to a late diagnosis of a femoral neck fracture, mainly due to both cognitive and motor impairments. High velocity trauma is a significant risk factor for developing AVN. In contrast to literature, a Delbet type IV fracture was significantly associated with AVN. A type IIR fracture has a higher possibility to develop AVN than a normal Delbet type II fracture. As the incidence of pediatric femoral neck fractures is low, the size of a study population is limited. Nevertheless, AVN is still a life altering complication leading to additional surgical treatments, hospital stays and impairment of daily life activities. Therefore, further research is needed to better understand the mechanisms of underlying risk factors and to develop strategies for the prevention and management of AVN in the pediatric population. Hence multicenter studies with a bigger study population are crucial.

Meta AnalysisOptimal timing of stabilization and operative technique for extremity fractures in polytrauma patients: a systematic review and meta-analysis.
In polytrauma patients, injuries involving the extremities are frequently seen. Treatment concepts vary from early definitive care to temporary fixation and delayed definite stabilization. This analysis therefor aims to illuminate the impact of timing for operative stabilization of extremity fractures on outcome factors in adult polytrauma patients. ⋯ The results indicate that immediate surgical treatment by nailing is superior to delayed treatment or a staged surgical approach in stable polytrauma patients with long-bone fractures. As there is a lack of clear evidence regarding the optimal timing for definitive operative stabilization of extremity fractures in polytrauma patients, further high-quality studies are essential to enhance the certainty of evidence and provide more conclusive treatment algorithms.

An open source convolutional neural network to detect and localize distal radius fractures on plain radiographs.
Distal radius fractures (DRFs) are often initially assessed by junior doctors under time constraints, with limited supervision, risking significant consequences if missed. Convolutional Neural Networks (CNNs) can aid in diagnosing fractures. This study aims to internally and externally validate an open source algorithm for the detection and localization of DRFs. ⋯ This open-source algorithm effectively detects DRFs with high accuracy and localizes them with moderate accuracy. It can assist clinicians in diagnosing suspected DRFs and is the first radiograph-based CNN externally validated on patients from multiple hospitals.

Biomechanics of flail chest injuries: tidal volume and respiratory work changes in multiple segmental rib fractures.
Flail chest (FC) injuries are segmental osseous injuries of the thorax that typically result from high-energy blunt trauma and regularly occur in multiple trauma (MT) patients. FC injuries are associated with paradoxical chest wall movements and, thus, have a high risk of respiratory insufficiency or even death. An increasing number of studies recommend an early surgical stabilization of FC injuries, but a definite trigger that would indicate surgery has, thus far, not been identified. ⋯ This study presents an FE model of the thorax of a patient who presented to our clinic as an MT patient with an FC injury. The FE model fulfills physiologic active breathing patterns and simulates an FC injury's paradoxical movement, realistically depicting clinical observations. The FE model showed that the number of consecutive ribs involved in the flail segment and the length of the flail segment significantly impacted active breathing concerning tidal volumes and respiratory work. With this, we have made the first step to define a trigger for surgery.
