Abstract: A hyperextension brace includes an upright support frame and a sternum pad positioned at one end of the upright support frame and a pubic pad positioned at the opposite end of the upright support frame. The brace further includes self-adjusting connectors for pivotally attaching the pads to the ends of the vertical support frame. The self-adjusting connectors comprise a one-piece structure having a generally flat web section integrally molded with an elongated, narrow recessed portion projecting from and reinforcing the web section. The recessed portion has an open end opening into an internal cavity for slidably receiving the end portions of the upright support frame. The one-piece connector further includes a U-shaped flange section integrally molded with and extending away from an end of the recessed portion opposite from its open end.

Abstract: A cervical traction collar capable of ambulatory use by a patient comprises a pair of elongated overlying semi-rigid flexible upper and lower support members secured at their ends to encircle the neck, with releasable attachment means such as Velcro fasteners securing the overlying upper and lower support members for adjusting the height of the collar. A tubular, flexible, air-inflatable bladder is secured to the collar so as to project downwardly away from a bottom edge of the lower support member continuously around the bottom of the collar. The bladder is filled with air under pressure from a manually operated air pump to inflate the bladder so that it presses downwardly against the shoulder region of the patient continuously around the lower neck region.

Abstract: Several knee stabilizing braces include an articulated knee joint support having upper and lower support arms, a first hinge bar pivoting on the upper and lower support arms and extending diagonally between them, and a second hinge bar pivoting on the upper and lower support arms and extending diagonally in an opposite direction for intersecting the first hinge bar. The two hinge bars allow relative rotation of the support arms while resisting relative forward or rearward sliding motion of each arm. Adjacent ends of the arms rotate into contact when they rotate to an upright position to stop further rotation beyond the upright position. One preventive knee brace has the upper and lower arms releasably affixed to flexible cuffs wrapped around the patient's upper and lower leg to hold the brace adjacent the knee joint.
