  2. Hip replacement - Wikipedia

    en.wikipedia.org/wiki/Hip_replacement

    Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi/semi (half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures.

  4. Hip dislocation - Wikipedia

    en.wikipedia.org/wiki/Hip_dislocation

    Hip dysplasia is a congenital condition in which the hip is deformed in a way that decreases the congruency between the head of the femur and the acetabulum of the pelvis. Bony congruence is a stabilizing factor to the hip joint, so the decrease in this conferred by hip dysplasia makes one more susceptible to dislocation. Diagnosis

  7. Bone grafting - Wikipedia

    en.wikipedia.org/wiki/Bone_grafting

    A surgeon places a bone graft into position during a limb salvage. Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk ...

  8. Hip prosthesis zones - Wikipedia

    en.wikipedia.org/wiki/Hip_prosthesis_zones

    After hip replacement, hip prosthesis zones are regions in the interface between prosthesis material and the surrounding bone. These are used as reference regions when describing for example complications including hip prosthesis loosening on medical imaging. Postoperative controls after hip replacement surgery is routinely done by projectional ...

  9. Stress shielding - Wikipedia

    en.wikipedia.org/wiki/Stress_shielding

    Stress shielding. Stress shielding is the reduction in bone density ( osteopenia) as a result of removal of typical stress from the bone by an implant (for instance, the femoral component of a hip prosthesis ). [1] This is because by Wolff's law, [2] bone in a healthy person or animal remodels in response to the loads it is placed under.
