Carpal tunnel syndrome associated with amyloidosis

Abstract

Introduction: Amyloidosis features protein deposition in the organs and tissues and has been associated with carpal tunnel syndrome (CTS) when it occurs in the wrist. The objective is to describe a case series of patients undergoing surgery for CTS associated with amyloidosis. Methods: The study included 12 patients who underwent surgery to treat CTS in whom amyloidosis was proven by biopsy; the follow-up period was 5 years. The patients were evaluated by clinical tests, electroneuromyography, radiological images, and biopsy. Results: All patients presented with musculoskeletal complaints, severe symptoms of median nerve compression, and changes on neurophysiological tests. Surgery, synovectomy, and biopsy were performed. In the postoperative period, five patients (41%) developed chronic pain and reflex sympathetic dystrophy. Conclusion: A higher frequency of postoperative pain was observed in the patients, demonstrating the need for caution in the approach and treatment of this association.
