Unusual coalition of the carpal bones with simian crease: a case report.

We present a case of scapholunate coalition with absent fifth metacarpal on one hand, and scapholunate triquetral coalition on the other hand. The patient was asymptomatic, though he was aware of the deformity of the little and ring fingers on the right hand. No treatment was offered as the deformity was not incapacitating and the syndactyly did not interfere with hand function.
