Background: Scaphocapitate syndrome is a rare variety of perilunate instability, described as a trans-scaphoid, trans-capitate fracture, with rotation of the capitate head either 90° or 180°.
Methods: We present a unique case of scaphocapitate syndrome in which the rotated proximal capitate fragment expelled into the carpal canal.
Results: The capitate head was extricated from the carpal tunnel via the volar approach, and was anatomically aligned and fixed through the dorsal approach using two 2.0 mm headless compression screws. The scaphoid fracture was then also reduced through the dorsal approach and stabilized with a 2.5 mm headless compression screw. All intercarpal ligaments appeared intact.
Conclusions: Volar dislocation of the proximal capitate into the carpal tunnel in scaphocapitate syndrome presents a unique challenge that can be addressed with a combined volar and dorsal approach.

Long-term outcomes after capitate fractures: a median 16-year follow-up.

Article Synopsis
- - The study aimed to evaluate the long-term clinical and radiological outcomes of capitate fractures, with a cohort of 23 patients identified from a larger group suffering wrist pain, and a follow-up conducted after an average of 16 years.
- - Out of the 16 eligible patients, the majority had healed capitate fractures with one case showing signs of osteoarthritis, although it did not cause any symptoms; none showed signs of avascular necrosis.
- - Functional assessments revealed minimal impairments, with patients reporting good hand function, normal wrist movement, and strength, indicating a low risk of developing posttraumatic arthritis in the surrounding joints.
Capitate Proximal Fragment Migration Compressing the Median Nerve in Scaphocapitate Fracture: A Case Report.

BACKGROUND Scaphocapitate syndrome is a rare clinical entity consisting of a combined scaphoid and capitate fracture along with a 90- or 180-degrees rotation of the proximal capitate fragment. The syndrome is scarcely described in the literature, with proximal migration of the capitate fragment being reported only by Mudgal et al in 1995. Concurrent compression of the median nerve is a highly unfortunate event, suggesting a unique case presented here.

Introduction: Scapho-capitate syndrome is a rare variety, usually occur during high-energy trauma leads to fracture of scaphoid and capitate with 180 rotation of proximal fragment of capitate.
Case Report: We present a unique case of chronic neglected scapho-capitate syndrome, in which the rotated proximal fragment of capitate along with the early degenerative changes in capitate and lunate.
Result: Exploration of the wrist by dorsal approach, fracture fragment was resorbed and non-amenable for fixation.

Scaphocapitate syndrome is a rare injury where the proximal pole of the capitate rotates 90 to 180 degrees. The proximal pole of the capitate, thought to receive its vascular supply retrograde, is rendered avascular in such cases. However, recent evidence of low rates of avascular necrosis in displaced capitate fractures, and new vascular studies of the capitate, challenge this paradigm.
