Contact pressures from an instrumented hip endoprosthesis.

摘要: A pressure-measuring Moore-type endoprosthesis was implanted in a seventy-three-year-old patient who had sustained displaced fracture of the femoral neck. The measurement and telemetry contact pressures hip began operating room, data were acquired periodically for more than thirty-six months. Unexpectedly high localized between acetabular cartilage prosthesis recorded. Early period recovery, activities such as using bedpan or performing isometric exercise produced that close to those recorded during normal walking. highest pressure, eighteen megapascals, one year postoperatively, while rising from chair. High occurred superior posterior aspects acetabulum.
