Examples
-
The ulnar nerve, D E, lies on the ulnar border of the artery, and both are in general to be found ranging along the radial side of the tendon of the flexor carpi ulnaris muscle, T, and the pisiform bone, G.

-
Whenever circumstances may call for placing a ligature on the ulnar artery, as it lies between the superficial and deep flexor muscles, in the region of I L M, Plate 16, the course of the vessel may be indicated by a line drawn from a central point of the forearm, an inch or so below the level of the inner condyle -- viz., the point F, and carried to the pisiform bone, T.
Surgical Anatomy Joseph Maclise
-
The fibers end in a tendon, which occupies the anterior part of the lower half of the muscle and is inserted into the pisiform bone, and is prolonged from this to the hamate and fifth metacarpal bones by the pisohamate and pisometacarpal ligaments; it is also attached by a few fibers to the transverse carpal ligament.
-
The articular capsule is a thin membrane which connects the pisiform to the triangular; it is lined by synovial membrane.
-
The pisiform is about 1 cm. distal to the lower end of the ulna and just distal to the level of the styloid process of the radius; it is crossed by the uppermost crease which separates the front of the forearm from the palm of the hand.

-
This slip may be replaced by a muscular fasciculus arising from or near the pisiform.
-
There is a separate synovial membrane between the pisiform and triangular.
-
The ligaments connecting the pisiform bone are the articular capsule and the two volar ligaments.
-
The two volar ligaments are strong fibrous bands; one, the pisohamate ligament, connects the pisiform to the hamate, the other, the pisometacarpal ligament, joins the pisiform to the base of the fifth metacarpal bone (Fig. 334).
-
The fifth runs between the adjacent margins of the triangular and pisiform bones.
