An Isolated Ring Finger Metacarpal Shaft Fracture? – Beware An Associated Little Finger Carpometacarpal Joint DislocationFrom the Department of Orthopaedic Surgery, Tan Tock Seng Hospital, 11 Jalan Tan Tock Seng, Singapore Correspondence: Dr Winston Y.C. Chew, Department of Orthopaedic Surgery, Tan Tock Seng Hospital, 11 Jalan Tan Tock Seng, Singapore 308433, Singapore. Tel.: +65-63577713; fax: +65-63577715; E-mail: winston_chew_yc{at}ttsh.com.sg Dislocations of the ulnar carpometacarpal joint are easily missed because of a low index of suspicion as well as their subtle clinical and radiological features. Often, the presence of a more obvious adjacent injury also draws attention away from the carpometacarpal joint. Two cases of ring finger metacarpal shaft fractures with associated little finger carpometacarpal joint dislocations are presented. In both cases, the metacarpal fractures were diagnosed but the carpometacarpal joint dislocations were initially overlooked. The presence of an apparently isolated ring finger metacarpal fracture due to an indirect force should raise the possibility of an associated carpometacarpal joint injury.
