TRAPEZOID ROTATIONAL BONE GRAFT OSTEOTOMY FOR METACARPAL AND PHALANGEAL FRACTURE MALUNIONFrom the Department of Hand Surgery, Singapore General Hospital, Outram Road, Singapore Correspondence: Dr Fok-Chuan Yong, Senior Consultant Hand Surgeon, Department of Hand Surgery, Singapore General Hospital, Outram Road, Singapore 169608, Singapore.

E-mail:yong.fok.chuan{at}sgh.com.sg Metacarpal and phalangeal fracture malunions with significant angulation deformity are associated with bone shortening, prominence of the metacarpal head in the palm or pseudoclaw deformity and may be symptomatic. If so, they may need corrective osteotomy procedures. Conventional methods of closing, or opening, wedge osteotomy do not restore the length of the bone exactly. Simultaneous correction of the angular deformity and restoration of bone length can be addressed by a trapezoid rotational bone graft osteotomy. A double osteotomy is done and the segment of bone is rotated and re-inserted as a bone graft. This was done successfully in four metacarpal and two phalangeal fracture malunions with angulation deformities.
Key Words: metacarpal phalangeal malunion trapezoid osteotomy
