Congenital true complete symphalangism of all proximal interphalangeal joints of hands with carpal anomalies: a case report.

Symphalangism is a rare condition which manifests in either PIP or DIP joint congenital fusion. Symphalangism may be with some other skeletal deformities. In our case, all PIP joints of both hands were fused with bilateral hypoplasia of carpal bones and Minaar type III lunatotriquetral coalition congenitally. No motion was detected in PIP joints with absence of cutaneous creases over all PIP joints. Radiologically, carpal hypoplasia and lunatotriquetral coalition were seen in all fingers with the absence of PIP joints. The patient's skeletal survey revealed no other pathology. He had no complaints related to his hands. So, regular follow-up was recommended. This pathology was presented as rarely observed although clinical problem is usually not so much.
