Open dislocation of the trapezoid

Various Diagnostic and Treatment Pitfalls of Combined Fracture Dislocations of Trapezoid and Multiple Carpometacarpal Joints

We report a rare case of combined fracture dislocations of the trapezoid and multiple carpometacarpal joints that became chronic due to inappropriate treatments. Although an acceptable clinical result was obtained with limited intercarpal fusion, correct diagnosis and initial treatments including anatomical reduction and fixation for obtaining a good clinical result, are important for complex trapezoid injury.

Combined dislocation of the trapezium and the trapezoid: a case report with review of the literature

Dislocation of the either the trapezium or the trapezoid are both rare injuries, even among carpal dislocations. We report a case of combined volar trapezium dislocation and dorsal trapezoid dislocation with other concomitant injuries. A review of the literature regarding trapezium and trapezoid dislocations as well as the treatment of these injuries is presented.

In situ rotational dislocation of the trapezoid associated with carpal-metacarpal dislocations

A rare case of in situ rotational dislocation of the trapezoid was described after dislocation of the index and long carpal-metacarpal joints. Due to the difficulty in visualising the trapezoid on plain radiographs, there was a delay in assessing the full extent of the injury. However, after further imaging, the case required open reduction and internal fixation. Therefore, in cases involving high energy dislocations of the second and third metacarpal CMC joints, injury to the peri-trapezoid ligaments should be considered. A pre-operative CT scan or, if not available, open fixation of the CMC joints and trapezoid, is recommended.

Carpal fractures in athletes excluding the scaphoid

A wide range of hand and wrist injuries occur in today's recreational and elite athletes and account for 3% to 9% of all sports injuries. The onus is on the physician to discriminate between injuries that can be managed with an early return to sport, and those injuries that place the athlete at risk of further injury if they are not managed aggressively from the outset. The physician and the athlete must understand the balance between safe, early return to sport, and prompt surgical treatment that prevents late disability.

Carpal fractures excluding the scaphoid

Although carpal fractures other than of the scaphoid are uncommon, vigilance in diagnosing these potentially serious fractures is paramount to early and effective treatment. Physical examination and standard plain radiographs may reveal only subtle findings. Use of special radiographic views and computed tomography may help elucidate the diagnosis. Treatment is particular to each fracture. Nondisplaced fractures should be treated nonoperatively. For intra-articular carpal bone fractures, virtually any amount of displacement is unacceptable and requires reduction and fixation. This article organizes current knowledge of these potentially difficult fractures, with a table of diagnosis and treatment guidelines.

Dorsal dislocation of the trapezoid

Report of a dorsal dislocation of the trapezoid after a benign trauma, with only moderate symptoms and signs, without the necessity for further treatment.
