Periscaphoid and Lunate Dislocation With an Intact Rotated, Scapholunate Interosseous Ligament: A Case Report.

Perilunate disassociation injuries are rare and may be missed in the acute setting. Prompt identification and management are critical to prevent late complications such as arthritis and instability. These injuries can present several patterns with soft tissue disruption, fracture, or a combination of both. In this report, we present a unique pattern of a periscaphoid, perilunte injury with an intact scapholunate interosseous ligament and describe our treatment strategy and outcome.
