title: Pressure changes in the carpal tunnel with movement of the pisiform bone.
abstract: Seven fresh cadaveric forearms were studied to investigate the effects of medial and lateral positioning of the pisiform bone on pressure within the carpal tunnel. The wick catheter, a device used to transmit interstitial fluid pressure, was inserted into the carpal tunnels of the cadavers. Pressures in the tunnel with the pisiform in a resting position, medial position, and lateral position were measured via a water manometer. A significant increase in pressure was noted between the resting position and both the medial and lateral positions ( p = 0.001). No significant difference was found between the medial and lateral positions ( p > 0.05). Findings suggest that the use of movement of the pisiform as a conservative treatment in carpal tunnel syndrome is questionable. J Orthop Sports Phys Ther 1982;4(1):47-50.
