Distal radius fracture osteosynthesis by volar locking plate: influence of epiphyseal screw positioning on risk of loss of reduction.

Ulnar variance is an important radiological parameter for good functional outcome after distal radius fracture osteosynthesis. Secondary loss of reduction due to radial shortening is a common complication after volar locking plate fixation. Some authors recommend beginning by placing the most ulnar epiphyseal screw, ensuring that it is positioned as close as possible to the distal radioulnar and radiocarpal joints.

A deep learning-based algorithm for automatic detection of perilunate dislocation in frontal wrist radiographs.

This study proposes a Deep Learning algorithm to automatically detect perilunate dislocation in anteroposterior wrist radiographs. A total of 374 annotated radiographs, 345 normal and 29 pathological, of skeletally mature adolescents and adults aged ≥16 years were used to train, validate and test two YOLOv8 deep neural models. The training set included 245 normal and 15 pathological radiographs; the pathological training set was supplemented by 240 radiographs obtained by data augmentation.

Pull-out resistance of connected K-wires for osteosynthesis: development of a numerical model.

A predictive finite element model was developed to investigate the best configuration of a fixation pins system consisting of two K-wires inserted in a synthetic model (Sawbones) at different angles and secured to a connecting rod. Two key parameters were considered to determine the best configuration delivering the higher pull-out strength and lower pull-out length: the diameter and insertion angle. Results show that as the diameter and insertion angle increased, the pull-out force increased, while the pull-out length decreased.

Does Google's Bard Chatbot perform better than ChatGPT on the European hand surgery exam?

Purpose: According to a previous research, the chatbot ChatGPT® V3.5 was unable to pass the first part of the European Board of Hand Surgery (EBHS) diploma examination. This study aimed to investigate whether Google's chatbot Bard® would have superior performance compared to ChatGPT on the EBHS diploma examination.

A Cadaveric Study Examining the Accuracy of Wireless Hand-Held Guided Ultrasound Injections Versus Blind Injections in the Flexor Tendon Sheath.

Purpose: Hand-held ultrasound (HHUS) is gaining popularity among clinicians. Although its use for procedural guidance could have several advantages in hand surgery, other surgeons may wonder about its added benefits. This cadaveric study aimed to examine the hypothesis of increased accuracy of wireless HHUS-guided injections versus that of blind injections into the flexor sheath.

Semi-occlusive dressing versus surgery in fingertip injuries: A randomized controlled trial.

Objectives: No gold-standard treatment has been established for the management of distal digital amputation in Ishikawa zones II and III. The objective of this study was to compare the results of management of fingertip amputation by semi-occlusive dressing versus surgery. The principal hypothesis was that a semi-occlusive dressing results in better recovery of sensory function than a digital flap.

Targeted muscle reinnervation in upper extremity amputation in military hand surgery: A systematic review.

Introduction: Targeted Muscle Reinnervation (TMR) is a surgical technique utilized to alleviate post-amputation neuroma pain, reduce reliance on narcotic pain medication, and enhance control of prosthetic devices. Motor targets for upper extremity TMR vary depending on injury patterns and amputation levels, with conventional transfer patterns serving as general guides. This study aims to summarize the common patterns of TMR in transradial and transhumeral amputations, focusing on anatomic and surgical considerations.

Technique, Indications and Limitations of a Minimally Invasive Approach to Treat Distal Radius Fractures and Malunions.

The minimally invasive approach can be used for volar locking plate fixation of distal radius fractures. It offers the advantage of preserving ligamentotaxis, which facilitates the reduction and the small size of the scar improves the esthetic result of the procedure. It is indicated for extra-articular fractures of the distal radius.

Preliminary stage in the development of an artificial intelligence algorithm: Variations between 100 surgeons in phase annotation in a video of internal fixation of distal radius fracture.

Introduction: In order to be used naturally and widely, an artificial intelligence algorithm of phase detection in surgical videos presupposes an expert consensus defining phases.

Objectives: The aim of the present study was to seek consensus in defining the various phases of a surgical technique in wrist traumatology.

Methods: Three thousand two hundred and twenty-nine surgeons were sent a video showing anterior plate fixation of the distal radius and a questionnaire on the number of phases they distinguished and the visual cues signaling the beginning of each phase.

Methods of assessment of the level of surgeons for minimally invasive fixation of distal radius fractures: "expertise" versus "performance".

Introduction: The results of surgical techniques vary depending on the level of the surgeon's experience. The level of expertise can be evaluated quantitatively or qualitatively. In this study, we evaluated the duration of the procedure and the size of the incision of minimally invasive fixation of distal radius fractures as a means of grading expertise and surgical performance.
