BackgroundProximal row carpectomy (PRC) is often recommended for advanced-stage Kienböck's disease (KD), although there is no standardized treatment protocol. This study aimed to evaluate the efficacy of the PRC in managing KD. MethodsA literature review and a clinical case study were conducted on a 40-year-old male with stage 3 KD. ResultsPostsurgery, the patient reported mild discomfort but significant functional improvement, with the Disabilities of the Arm, Shoulder, and Hand (DASH) score decreasing from 87 to 44. Observations included reduced pain, enhanced wrist trophism, and an expanded range of motion. ConclusionsThe PRC demonstrated positive outcomes, including symptom alleviation and functional restoration, supporting its viability as a tailored surgical intervention for KD, improving quality of life and reducing hospital stay.
