摘要:
Methods and apparatus for orthopedic replacement of the hip through three incisions with a modular prosthetic system assembled in vivo while substantially preserving muscles and soft tissues around the hip joint resulting in reduced healing time and decreased risk of dislocation. A prosthetic femoral stem is inserted into the femur. A prosthetic femoral neck is inserted from a point along the side of the patient's body and into the side of the femur and through a lateral bore in the prosthetic femoral stem to join the prosthetic femoral head. The methods and apparatus include structures and techniques for fixing or enhancing interconnection of implant components, such as by increasing the interconnection in an interference fit with one or more tapers, threads, and/or cooling of components prior to assembly.
摘要:
Systems and methods for placement of both the prosthetic acetabular cup and the prosthetic femoral head which takes account of the patient's particular anatomy, with inter-operative testing of the patient's body to find an optimum positioning (angles) for the components. The system allows a procedure with less pre-operative and inter-operative imaging, providing for reduced radiation exposure for doctors and patients.

摘要:
Methods and apparatus of the present invention provide for orthopaedic replacement of the hip while substantially preserving muscles and soft tissues around the hip joint resulting in reduced healing time and decreased risk of dislocation following the procedure. In an exemplary embodiment, an intramedullary rod 1502 is inserted longitudinally into the femur. A prosthetic femoral neck 3102 is then inserted from a point along the side of the patient's body and into the side of the femur and through a pre-existing lateral bore in the intramedullary rod 1502 and through the remainder of the femur to join the prosthetic femoral head 1102. The methods and apparatus include structures and techniques for fixing the prosthetic femoral neck 3102 in relation to the intramedullary rod 1502.

摘要:
Methods and apparatus for orthopedic replacement of the hip and hip fracture fixation devices include structures and techniques for fixing or enhancing interconnection of implant components, such as by increasing the interconnection in an interference fit with one or more tapers, threads, and/or cooling of components prior to assembly. For example, a prosthetic femoral neck implant can include a thread and a Morse taper for lockable attachment to a prosthetic femoral head and/or intramedullary stem.
摘要:
Methods and apparatus of the present invention provide for orthopaedic total replacement of the hip while substantially preserving muscles and soft tissues around the hip joint resulting in reduced healing time and decreased risk of dislocation following the procedure. In an exemplary embodiment, the acetabulum is prepared and fitted with a prosthetic acetabular cup 702 and a prosthetic femoral head 1102 is fitted into the prosthetic acetabular cup 702. An intramedullary rod 1502 is inserted longitudinally into the femur. A prosthetic femoral neck 3102 is then inserted from a point along the side of the patient's body and into the side of the femur and through a pre-existing lateral bore in the intramedullary rod 1502 and through the remainder of the femur to join the prosthetic femoral head 1102.
