Orthopedic hinge assembly

摘要

The assembly has a pair of opposed exterior plates containing slots for receiving an adjustment wheel threaded to a screw positioned in close association with gear teeth juxtaposed to the second end portion of a first elongated bar. The exterior plates enclose the second end of two elongated bars. The first end of each bar is positioned within oppositely positioned pockets in an orthopedic device. Gear teeth integral with the second end portion of the second elongated bar engage the gear teeth on a cam gear juxtaposed to the second end portion of the first elongated bar. The exterior plates are locked together with rivets to hold the gear teeth in position and permit movement or locking of the second elongated bar by manipulation of the adjustment wheel.
