Kirk Watson MD, in, Plastic Surgery Secrets Plus (Second Edition), Preventive measures for PLCS consist of appropriate treatment of, Mordechai Vigler MD, Steve K. MD, in, The pisiform forms the ulnar wall of the Guyon tunnel, which contains the ulnar nerve and artery. Small non-displaced isolated lunate fractures are usually managed with immobilization in a short arm cast for 6 weeks.29 Inclusion of the thumb IP joint in the cast for these fractures is based on physician preferences. Pisiform bone shown in red. Left hand anterior view (palmar view). [2], Studies looking at the effect of Hox gene knockouts on the formation of the pisiform in mice have suggested that the modification of Hoxa11 or Hoxd11 genes, or the downstream targets they affect, could have acted as the mechanism for the reduction we see in the human pisiform condition.[2]. Fractures can occur following a direct blow to the dorsum of the hand or from a fall resulting in extreme extension of the wrist. 26). [2] It is suggested that due to the pisiform's surprisingly large range of movement along its articulation surface with the triquetral bone (about 1cm of movement is allowed), contraction of the flexor carpi ulnaris is necessary for the pisiform to remain stable enough for the abductor digiti minimi to function effectively. The causes of calf strain are typically due to sports that require sudden changes in the direction of play when undertaking the sport or when performing jumping activities related to the sport.
