Recurrent Osteoblastoma of the Hamate Bone

Abstract

An osteoblastoma in a carpal bone is very rare and presents a problem of reconstruction after wide tumour excision. We report a case of recurrent osteoblastoma of the right hamate bone with involvement of the ulnar carpal bones and soft tissues that was successfully treated by en bloc resection, temporary interposition of bone cement and fixation with K-wires, followed by reconstruction with a free vascularized iliac crest flap, tailored to the exact size of the defect, in a second procedure. Rapid fusion was achieved and hand function preserved with no evidence of recurrence 3 years postoperatively.

Isolated Osseous Excision in the Adult Carpus: A Narrative Review

“…When ABCs of the hamate have complete cortical involvement, total hamate excision is a reasonable option that maintains wrist function and stability at the 3-year mark. 86 Osteoblastomas of the hamate have a tendency to recur after curettage and can be treated with total excision and carpal fusion involving either a vascularized iliac free flap 87 or a fifth carpometacarpal (CMC) arthrodesis. 88 Both techniques provide positive functional outcomes with no osteoblastoma recurrence at the 3- and 4-year follow-up, respectively.…”
