Scaphoid and Lunate Dislocation with Complete Soft-Tissue Avulsion: A Case Report

Kevin H Phan et al. JBJS Case Connect. 2016 Jul-Sep.

Abstract

Case: We describe an intercarpal dislocation with proximal and rotatory displacement of the lunate and with volar and radial dislocation of the scaphoid; both bones were stripped of soft tissue. Treatment involved ORIF (open reduction and internal fixation). Three years postoperatively, the patient had a DASH (Disabilities of the Arm, Shoulder and Hand) score of 10, equivalent grip strength and 50% wrist palmar flexion and 98% wrist dorsiflexion compared with the uninjured side, and radiographic evidence of posttraumatic arthritis.

Conclusion: Treatment of simultaneous divergent lunate and scaphoid dislocation with loss of nearly all soft-tissue attachments and vascular supply by means of ORIF and repair of soft-tissue structures can result in a favorable intermediate-term functional outcome and may be superior to other salvage procedures such as proximal row carpectomy.
