Improved true bi-pivotal orthopaedic and orthotic hinge with incremental motion control

摘要

The hinge has optimally spaced pivots in which extension and flexion travel of each independently pivoted hinge arm is limited by a series of planar metal stops acting on both arms and in both directions. Each stop has first and second pairs of angled stop faces for limiting extension at optionally different angles and first and second pairs of angled stop faces for limiting flexion at optionally different angles. The hinge arms are d between a front plate and a back plate and pivot means for each hinge arm also serve as securing means securing the plate and hinge arms together. Each stop is secured by a single screw which passes through one plate. Stops are mounted in the internal flexion angle of the hinge. <IMAGE>
