Abstract

Diseases of the pisiform triquetral (P-T) joint and the pisiform itself are often treated with excision of the pisiform bone. The flexor carpi ulnaris (FCU) tendon inserts on the volar aspect of the pisiform, suggesting a loss of strength in wrist flexion following excision of the bone. Isometric and dynamic, isokinetical measurements were made using a strain-gauge dynamometer (Cybex II). Slight postoperative reduction of wrist flexion strength, compared with the contralateral wrist, was noted but not of clinical significance. It is concluded that one should not refrain from excision of the pisiform bone for fear of considerable strength loss in wrist joint flexion.
