Coalition of trapezoid, capitate, and metacarpal: a case report

Abstract

Carpal coalition is a rare wrist anomaly. A coalition can be an isolated condition, but it can be observed as a component of a congenital syndrome as well. Carpal coalition is usually asymptomatic and de- tected incidentally. It is most frequently encountered as lunate-triquetral coalition, followed by capito- hamate coalition. Other coalition types are very rare. In this case report, we present a case in which the patient applied with complaints of pain, and in whom a coalition of capitate-trapezoid- second and third metacarpal was detected.
