Kienbock’s disease-avascular necrosis of lunate operated with excisional arthroplasty and Palmaris longus graft interposition

Abstract

A vascular necrosis of the Lunate bone is also termed as Kienbock's disease. It's a rare disease of unknown etiology and occurs mainly in the age group between 20 -40 years with males affected twice as commonly as females. Here we present an 29 year old Female presented with pain in her left (nondominant) wrist for the past one year. The pain was progressively increasing in nature with difficulty in carrying out activities of daily living like holding a glass and toilet activities. MRI revealed a diagnosis of grade 3 Kienbock's disease. Interposition arthroplasty with ipsilateral coiled Palmaris longus tendon was done and followed up for the end result and functional outcome.
