A case of carpal instability complex mimicking volar intercalated segmental instability (VISI) after acute injury was successfully treated. Ligament repair and Kirschner wire fixation led to positive clinical outcomes in this wrist injury.

Area of Science:

Orthopedic Surgery
Hand and Wrist Surgery
Musculoskeletal Research

Background:

Carpal instability complex can present with varied clinical manifestations.
Volar intercalated segmental instability (VISI) is a specific pattern of carpal malalignment.
Acute injuries can precipitate complex carpal instability.

Observation:

A patient presented with symptoms suggestive of VISI following an acute injury.
Diagnostic evaluation revealed an underlying carpal instability complex.
The apparent VISI was a consequence of the acute traumatic event.

Findings:

Surgical intervention involving ligament repair was performed.
Kirschner wire fixation was utilized to stabilize the carpal structures.
