ABSTRACT:
A device for immobilizing the knee of an individual is an open-ended, tubular shell formed of an integral piece of semi-rigid material having portions shaped to receive the lower thigh, knee, and upper calf of the individual. The device is easily slipped on and off by means of expansion of a longitudinal opening which bifurcates one side of the device. After the device is placed around the individual's leg, the opening can be closed to tighten the shell around the leg forming the shell into an essentially closed open-ended tube which has substantial structural strength to provide secure immobilization. The thigh and calf portions of the device have flat areas to prevent rotation of the individual's leg within the device. The thigh portion extends at an angle from the calf portion sufficient to immobilize the individual's knee in a flexed position in which the ligaments are relaxed.
