Tricortical Bone Grafting with Limited Midcarpal and Carpometacarpal Fusion for the Treatment of Giant Cell Tumor of the Capitate

Abstract

Background Giant cell tumor (GCT) of capitate is a rare lesion that is challenging to treat. Case Description We present a case of a 12-year-old girl suffering from a GCT of the capitate. Wide excision combined with adjuvant treatment including hydrogen peroxide, alcohol, tricortical bone grafting, and limited midcarpal and carpometacarpal fusion achieved good functional result without evidence of tumor recurrence or radiocarpal degeneration at 8 years postoperatively. Clinical Relevance In this case with long-term follow-up, surgical treatment of capitate GCT with limited midcarpal and carpometacarpal fusion led to a satisfactory outcome despite the alteration of wrist kinematics.

Isolated Osseous Excision in the Adult Carpus: A Narrative Review

“…3 With total capitate excision, augmentation with CMC arthrodesis yields excellent long-term results with no recurrence at the cost of decreased wrist motion. 91,92 Excision without any additional reconstructive effort has also been suggested and shows remarkable hand function even at the 5-year mark. 93 A highly aggressive osteochondroma that grew dorsally from the capitate and ruptured the extensor digiti minimi tendon was managed with complete capitate excision and tendon transfer to the common extensor tendon of the ring finger with full recovery of small finger extension at 3 months and no tumor recurrence.…”
