Application of prosthetics-orthotics principles to treatment of fractures.
1 School of Medicine, University of Miami, Jackson Memorial Hospital, Miami, Fla. 33152. Greater knowledge and understanding of bioengineering by the prosthetics and orthotics industries during the past twenty years have resulted in the development of highly functional and sophisticated appliances. For example, modern prostheses for lowerand upperextremity amputees are now designed with proper ...
متن کاملRecent advances in below-knee prosthetics.
' Executive Director, Committee on Prosthetics Research and Development, National Research Council, 2101 Constitution Ave., N. W., Washington, D.C. 20418. The concept of constructing a belowknee prosthesis with side joints and a thigh lacer was set forth by the Dutch surgeon Verduin in 1696 (Fig. 1) and followed universally until the advent of the patellar-tendon-bearing prosthesis in the late ...
متن کاملSome experience with patellar-tendon-bearing below-knee prostheses.
AN THE latter part of 1958, prothetists of the Limb and Brace Section of the U. S. Veterans Administration Prosthetics Center, New York City, were indoctrinated in the technique of fabricating the patellar-tendon-bearing (PTB) cuff-suspension below-knee prosthesis. Preliminary experience encouraged VAPC to institute in the spring of 1959 a form of clinical study. Selection of the patients fitte...
متن کاملThe PTB Supracondylar-Suprapatellar Air-Cushion Socket
The patallar-tendon-bearing supracondy lar, suprapatellar air cushion (PTS-AC) below-knee (BK) prosthesis is a special modi fication of the supracondylar, suprapatellar suspension and the air cusion socket. The air cushion principle in combination with the patella tendon-bearing (PTB) prosthesis was introduced by Lyquist, Wilson, and Radcliffe (Fig. 1), (2) in 1965. It requires more accurate ...
متن کاملAnalysis of a below-knee patellar tendon-bearing prosthesis: a finite element study.
In this study, a finite element (FE) model of a below-knee prosthesis of patellar tendon-bearing (PTB) design, and several altered variations of the model have been constructed. A load of approximately 1.5 times normal body weight (984 N) was applied at the heel of the model to simulate heelstrike conditions. The "base" model was then analyzed and revised iteratively until a model which provide...
