Orthopaedic gel pad assembly

Abstract

An orthopaedic gel pad assembly includes a layer of gel, with a backing layer behind it, an apertured pad extending around the layer of gel and a thin plastic film extending over the front surface of the gel. The plastic film controls the configuration of the front face of the gel, and the gel may be recessed, or indented, and may protrude forwardly out from the apertured pad. Stiff orthopaedic supports may be provided to back up the gel pad unit.
