Tumeur à cellules géantes du capitatum traitée par résection large et arthrodèse lunatum – 3e métacarpien

Abstract

Background Giant cell tumor (GCT) of bone is rare in the carpus and only 11 cases have been reported in the capitate bone. The problem with this location is the high recurrence rate due to easy extension to the adjacent joint spaces and bones. Case description The case report concerns a 48 years old woman, with a GCT of the capitate diagnosed on curettage. The treatment consisted of large resection with lunatum-third metacarpal arthrodesis, with a successful union at 2 years follow-up, no recurrence and an acceptable function of the wrist. Literature review When treated by curettage (alone or with adjuvant procedures), the GCT of the capitate recurred in 4/5 cases. All tumors treated with large resection did not recur. Clinical relevance Recommended treatment of GCT of the capitate is resection with carpo-metacarpal arthrodesis.
