Kienbock's disease: Case report and review of the literature.

Kienböck's disease is a rare form of avascular necrosis affecting the lunate bone, typically seen in young adults and often resulting in chronic wrist pain and functional impairment. We present a case-based review of 3 young adults (2 males aged 20 and 30 years, and 1 female aged 28) with progressive dorsal wrist pain, reduced grip strength, and limited range of motion. Imaging revealed advanced lunate osteonecrosis, with Lichtman staging ranging from stage IIIa to IV. MRI and CT played a central role in diagnosis and treatment planning. Management varied according to disease stage, from conservative immobilization to surgical intervention. This report highlights the importance of early diagnosis, accurate staging, and tailored treatment strategies based on clinical presentation and surgical expertise.
