ABSTRACT:
An improved ratchet mechanism for a surgical boot is not susceptible to spontaneous rotation when the center of gravity of the weight of the patient's leg, the boot, and the support arm for the boot passes the axis of rotation of the ratchet mechanism. The ratchet mechanism includes a ratchet wheel which includes both ratcheting serrations which allow rotation of the support arm in only one direction and locking serrations which do not allow the support arm to rotate in either direction. A ratchet release allows such constraints on rotation to be removed by the surgeon or surgeon's assistant.
