Objective: Anatomic reduction and stabile fixation for immediate mobilisation and restoration of unrestricted function.
Indications: Instabile metacarpal fractures with or without malrotation, dislocated metacarpal fractures with malrotation or finger extension deficit, longitudinally shortened metacarpal fractures with finger extension deficit.
Contraindications: Persistent infections (empyema, osteomyelitis, phlegmon) SURGICAL TECHNIQUE: Longitudinal intermetacarpal incision along the fracture zone, debridement of the fracture zone with retainment of periost, anatomic reduction and retention of spiral fractures with at least two lag screws or retention of comminuted or transverse fractures with locking plate osteosynthesis while retaining periost.
Postoperative Management: Buddy splinting of the corresponding finger to enable immediate mobilisation without weight bearing for 6 weeks.
Results: Locking plate osteosynthesis and compression screw osteosynthesis after anatomic reduction of metacarpal fractures proved to be very reliable with a low complication rate and a good functional outcome (modified Mayo Wrist Score [MMWS]: mean 88 (20-100); Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire: mean 41(24-86)).

Background And Purpose: Hand fractures are commonly presented in emergency departments, yet diagnostic errors persist, leading to potential complications. The use of artificial intelligence (AI) in fracture detection has shown promise, but research focusing on hand metacarpal and phalangeal fractures remains limited. We aimed to train and evaluate a convolutional neural network (CNN) model to diagnose metacarpal and phalangeal fractures using plain radiographs according to the AO/OTA classification system and custom classifiers.

: Most metacarpal fractures are isolated, simple, closed, and stable fractures and located distally. They are often caused by accidental falls, strikes by humans, by objects or traffic accidents. The majority can be treated conservatively.

Our hypothesis evaluated whether IMS fixation for metacarpal fractures results in lower overall health care-associated costs in comparison to open reduction and internal fixation (ORIF).
Methods: A retrospective review of patients undergoing IMS fixation for metacarpal fractures at a single center during 2018 to 2022 was conducted.

Background: The lateral locking plate for the proximal humerus is currently the most commonly used surgical procedure for the treatment of elderly proximal humeral comminuted fractures. Previous studies have found that the rate of postoperative complications in patients of proximal humerus fractures with medial column involvement is relatively high. Through biomechanical methods, this study aims to investigate the effectiveness of the conventional lateral locking plate fixation along with the addition of the metacarpal supporting plate on the medial column in the treatment for proximal humeral fractures involving the medial column.

Background: Bennett's fracture, a fracture-dislocation of the base of the first metacarpal, poses significant challenges due to the unique biomechanics of the thumb's carpometacarpal (CMC) joint. Effective management is critical to restoring thumb function and preventing long-term complications such as arthritis and instability.
Objective: This article provides a comprehensive overview of Bennett's fracture, including its mechanism of injury, diagnostic considerations, and management strategies, with a focus on conservative and surgical options.
