Comparison of Ischial Containment and Subischial Sockets Effect on Gait Biomechanics in People With Transfemoral Amputation: A Randomized Crossover Trial.

Objective: To compare gait biomechanics of the Northwestern University Flexible Sub-Ischial Vacuum (NU-FlexSIV) Socket to the ischial containment (IC) socket.

Design: Randomized crossover trial with 2, 7-week periods.

Setting: Private prosthetic clinics and university research laboratory.

Comparison of Ischial Containment and Subischial Sockets on Comfort, Function, Quality of Life, and Satisfaction With Device in Persons With Unilateral Transfemoral Amputation: A Randomized Crossover Trial.

Objective: To compare comfort and functional performance of the Northwestern University Flexible Subischial Vacuum (NU-FlexSIV) Socket with the ischial containment (IC) socket in persons with unilateral transfemoral amputation.

Design: Randomized crossover trial with two 7-week periods.

Setting: Private prosthetic clinics and university research laboratory.

Quantification of Shear Stresses Within a Transtibial Prosthetic Socket.

Background: There is a paucity of objectively recorded data delineating the pattern of weightbearing distribution within the prosthetic socket of patients with transtibial amputation. Our current knowledge is based primarily on information obtained from finite element analysis computer models.

Methods: Four high-functioning transtibial amputees were fit with similar custom prosthetic sockets.

A feasibility trial of a prefabricated immediate postoperative prosthetic limb system.

In this feasibility trial, 32 consecutive patients undergoing transtibial or knee disarticulation amputation had application of a prefabricated immediate postoperative prosthesis in the operating room following lower extremity amputation. Partial weightbearing was initiated on the first postoperative day. Twenty-nine underwent primary amputation as a consequence of nonsalvageable gangrene or diabetic foot infection.
