Osteoblastoma of the trapezoid bone and triquetral bone: Report of two cases

Abstract

Osteoblastoma is a benign local aggressive tumor mostly localized in the vertebra or long bones. Carpal location and recurrence are extremely rare. Treatment options include either curettage or wide en bloc resection which causes functional disability in the hand and wrist and should be reserved only for recurrence. We present a case of recurrent trapezoid osteoblastoma previously treated with curettage of the trapezoid bone and a case of primary triquetral osteoblastoma.
