Pisiform-hamate coalition with ulnar neuropathy.
Two cases of pisiform-hamate coalition with compression of the ulnar nerve at the wrist are reported. Pisiform-hamate coalition is a rare entity previously thought to be exclusive to West Africans and without clinical significance. These cases occurred in white patients. This is the first description of a carpal coalition resulting in ulnar neuropathy at the wrist.
