A Rare Case of Chronic Lunate Dislocation Along With Avascular Necrosis of the Lunate With Median Nerve Compression Treated With Lunate Excision With Carpal Tunnel Release

A young 22-year-old male presented with complaints of pain, tingling, and numbness over his right wrist for 1 year and had a history of falls on his outstretched hand. Radiological evaluations such as X-rays were done, which showed a break in the proximal carpal arc. An MRI of the affected wrist was done. MRI findings are suggestive of avascular necrosis of the lunate along with lunate dislocation with marrow edema/contusion in the lunate. Complete disruption of the scapholunate, lunotriquetral, and radioscaphocapitate ligaments was noted. The patient was operated with lunate excision with carpal tunnel release and given strict pillow cover elevation in a volar slab.
