A prosthesis device for hip surgery replacement has a main body portion which is implanted in the femur of a patient. A series of adapters are provided from which one is selected. Each adapter has a tapered shank which is received a corresponding tapered bore in the main body portion forming a first lock therein. The adapter has tapered teeth which engage corresponding tapered teeth in the bore in the main body portion, forming a second lock. The adapter is indexed with respect to the main body portion. A method of use is disclosed.

Modular neck for femur replacement surgery

A prosthesis for femur replacement surgery has a stem which is received in the femur. The stem has a blind bore formed at an angle in the upper portion. A modular neck assembly is received in the blind bore. The neck assembly is formed at a desired angle with respect to the vertical axis of the stem. The neck assembly is keyed to the bore to obtain a desired degree of anteversion and offset by a desired rotation of the neck assembly within the bore. A unitary sleeve may be inserted in a canal in the femur to receive the stem and provide circumferential movement of the prosthesis within the femur canal. A porous coating is formed on the outer surface of the stem and the sleeve.

A method and apparatus for realigning the pelvis, femoral head, femur, trochanter, and acetabulum of a patient during a hip joint replacement procedure being performed on the patient. Prior to replacing the hip of the patient with a prosthesis, a pin is inserted into the patient's pelvis. The pin has a plurality of weakened areas of reduced cross-section formed along its length so that the pin is capable of being bent at approximately a 90.degree. angle at each of the weakened areas. The pin is used to establish a point of reference as to the leg length and the desired orientation of the prosthetic joint.
