Prosthetic hips are well known in the arts and have been successfully used
for many years. There are, however, some inherent health problems
associated with present art designs. All of the prosthetic hip designs
utilize a variety of materials. Most used are plastic, ceramic and metal
materials. One of the main problems associated with prior art prosthetic
hips involves friction generated between cup and ball. Friction
dislodges, from cup and ball surfaces, plastic, ceramic or metallic
fragments during a patient's normal motor functions. These particles
interact with the body's chemistry and may cause deleterious health side
effects. Rubbing action between cup and ball also produces ions which can
adversely affect the patient's health. It is therefore essential that
friction between prosthetic hip cup and ball is reduced to a minimum. The
design of the prosthetic hip presented herewith will alleviate some of
the unwanted friction between cup and ball.
