Abstract
We report a unique case of carpal reconstruction for capitate deficiency in a child. The patient is a 15-year-old girl who had a destructive giant cell tumor involving the capitate and hamate. To the author’s knowledge, this is the first case in which Achilles tendon interposition allograft was utilized to fill the bony void left behind by capitate and partial hamate excision. Arthrodesis was used as an adjunct for stabilizing the second and third proximal metacarpals. This resulted in a great functional and radiographic outcome with 7-year follow-up. In conclusion, when treating a carpal defect from capitate deficiency, if excision of the bone in its entirety is indicated, consideration for tendon allograft as an interposition graft may be given.
