Aneurysmal Bone Cyst Involving the Metacarpal Bone in a Child
Aneurysmal bone cysts associated with tubular bones of the hand occur rarely and require particular diagnostic and therapeutic management techniques. While optimal treatment has not been established, accepted treatments range from aggressive radical treatment, including en bloc resection and excision diaphysectomy with strut bone grafting, to relatively simple techniques, such as thorough curettage followed by bone graft. Aggressive treatment approaches may be optimal for the cases with articular surface involvement, full-bone invasion of the phalanx or metacarpal, or more than 1 recurrence. We report a monocentric case of aneurysmal bone cysts involving metacarpal bone in a child who achieved favorable outcome with curettage and morselized cancellous bone grafts.
In conclusion, despite the high risk of recurrence of ABC treated with curettage with bone grafting, the findings of the present case show that ABC of the metacarpal bone in children can be treated successfully with curettage followed by morselized autologous bone grafting without recurrence.
