Scapho - Capitate Fusion With Posterior Interosseous Nerve Neurectomy for Advanced Kienbocks Disease : A Case Report

Abstract

Scapholunate dissociation is the most common carpal instability. We are presenting an interesting case of a 24yr old male with scapholunate instability following trauma. Appropriate investigations were done and surgical intervention was done on the same day. The ruptured ligaments were repaired and bony components scapholunate and scaphocapitate were corrected and fixed. Patient was immobilized in plaster for 8 weeks following which active mobilization exercises were started. The functional results were excellent and we have reported them using the mayo wrist score. KEYWORDS: Slac wrist, scaphoid shift test, terry Thomas sign, scaphoid ring sign, scapholunate angle and capitolunate angle, Mayo wrist score. INTRODUCTION:The Scapholunate dissociation is an injury to ligaments in the wrist that can lead to loosening of carpal bones. The risk factors are Ulna minus configuration, slope of radial articular surface and Lunotriquetral coalition. The main pathology is rotatory subluxation of the Scaphoid bone.
