Kienbock's Disease (Avascular Necrosis of Lunate), Right Wrist

ICD-10 Code
M87.131

Avascular necrosis of the lunate bone in the right wrist, leading to pain and collapse.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with chronic, progressive right wrist pain localized to the dorsal aspect, exacerbated by gripping and weight-bearing activities. Reports associated stiffness, decreased range of motion, and intermittent swelling. No history of acute trauma. Symptoms consistent with Kienbockโ€™s disease (M87.131).

Clinical Examination Findings

Right wrist examination reveals localized tenderness over the lunate fossa. Range of motion is restricted in flexion/extension. Grip strength is diminished compared to the contralateral side. No signs of acute infection or neurovascular compromise. Radiographic findings demonstrate lunate sclerosis and/or collapse consistent with Kienbock's disease.

Treatment Protocol

Management plan includes activity modification, immobilization with a wrist splint, and non-steroidal anti-inflammatory drugs (NSAIDs). Referral for advanced imaging (MRI) to assess stage. Surgical consultation for potential revascularization, proximal row carpectomy, or fusion depending on Lichtman stage.
