Patent ID: 8795385

Claim:
An adjustable prosthetic socket having anterior and posterior sides and defining proximal and distal ends, the prosthetic socket configured to fit around and envelope a residual limb, comprising: a distal base adapted to support a distal end of a residual limb and located at the distal end of the socket; an elongate rigid spine located on the posterior side and extending upwardly from the distal base toward the proximal end; an elongate flexible spine located on the anterior side and extending upwardly from the distal base on an opposed side from the rigid spine and extending toward the proximal end; a plurality of lateral flaps generally extending laterally relative to a height of the socket and from at least one of the rigid and flexible spines, and forming a variable circumference to the socket between the proximal and distal ends, the circumference of the socket adapted to extend around the residual limb and increases in circumference from the distal base to the proximal end of the socket; wherein the flexible spine includes first and second anterior vertebrae hingedly connected to one another and extending upwardly in generally a same orientation to form at least in part the elongate flexible spine.
