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 (non-dominant) 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.
