Understanding the effects of hand dorsum coordinate systems on thumb metacarpal angle outcomes.

As an essential contributor to thumb and hand function, it is necessary to establish metacarpal (MC) kinematics to track thumb health and determine the efficacy of treatments. In the literature, several hand dorsum coordinate systems (CSs) have been utilized for MC angle calculations. These systems were determined using varied motion capture marker setups.

Carpometacarpal (CMC) joint dislocation is a rare injury that can be easily missed due to non-specific clinical signs and radiologic findings. We report a patient with an isolated and irreducible dorsal dislocation of the second CMC joint, which required an open reduction and K-wire transfixation. An extensor tendon was found to be interposed between the base and the trapezoid.

Article Synopsis
- * A case study of a 32-year-old male after a motorcycle accident revealed dislocations in four ulnar metacarpals and a fracture in the fifth, requiring open surgical intervention for successful realignment and stabilization.
- * Effective diagnosis and treatment of these injuries necessitate a high index of suspicion from medical professionals, with CT scans playing a key role, especially for late diagnoses, which usually require surgical reduction to restore anatomical structure.
Use of Mini TightRope® for Delayed Presentation of a Fifth Carpometacarpal Joint Dislocation.

Introduction: Isolated dislocations of the fifth carpometacarpal joint (CMCJ) are uncommon injuries of the hand that is often missed but can be diagnosed correctly with a high index of suspicion and adequate imaging. Treatment for chronic cases is usually open reduction with temporary fixation using Kirschner wires, but for this case, we used Mini TightRope® as well to allow for early finger exercise. The case presented here is unique because of a delayed dislocation of a CMCJ detected 9 weeks from initial injury which was treated with a novel form of fixation with Mini TightRope®.

Article Synopsis
- Hamate dislocations are uncommon injuries that can be challenging to diagnose and treat, often leading to missed cases and non-standard management.
- A case of a 34-year-old involved in a high-impact traffic accident is presented, revealing a hamate fracture that was successfully treated with open surgery, resulting in pain-free wrist motion after one year.
- The literature on hamate injuries is limited, with symptoms often being mild; however, thorough radiographic analysis and potential CT scans are recommended for accurate diagnosis, especially in high-energy injuries.
