Partial hip replacement implants are generally used to treat a hip fracture in an elderly patient, rather than a hip damaged by osteoarthritis, for which total hip replacement is a treatment. It is usually an emergency surgery that is essential due to a fall or other accident that fractures the hip. Partial hip replacement surgery in Delhi is more correctly known as “hemiarthroplasty,” or “hemi” means half of a joint because it replaces only the spherical part of the hip joint, not the cavity portion. A total hip replacement orthopedic implant, on the other hand, replaces acetabulum and the ball of the joint.
The most common reasons for fractures in the elderly are that they are fragile and not in good health. Your bones may be fragile due to osteoporosis, or they may be unstable in your feet and are more likely to stumble. It has been theorized that, at times, the hip bone of an older person can be weakened in such a way that it can really give in, causing it to fall, instead of the fall causing the hip to break, says orthopaedic in Delhi.
The treatment of hip fractures is dictated by the classification of the fracture and the viability of the head of the femur. Your surgeon will determine if your hip fracture can be repaired, or if the expected state of health and longevity qualify you for a partial hip replacement in Delhi, or if other aspects such as advanced osteoporosis require the need for a total hip replacement.
Partial Hip Implants
Unlike the total hip replacement implants that have a separate ball and stem, the classic partial hip replacement implants, pioneers in the 1960s and still in use today, include a complete ball design and stem. The unipolar design features a solid stem and a metal ball that replaces the femoral head and upper femur (thigh bone). The Thompson and Austin Moore prostheses are common examples of unipolar design, where hip movement occurs directly between the acetabulum (the hip cavity) and the prosthesis. Other more recently developed partial hip replacement implants are modular, allowing different combinations of head, stem and neck length, explains orthopaedic in Delhi.
Modular and unipolar devices are exclusive to partial hip replacement procedures and would not be considered as treatment for an arthritic hip, which needs a total hip replacement in west Delhi.
- An Austin Moore implant that is used without cement (bone grows through the holes)
- A Thompson prosthesis that is usually placed with bone cement.
- A modular prosthesis with a separate spherical head.
Like total hip replacement implants, partial hip replacement implants come in cementless and cemented versions. The means, the orthopedic implant can be placed in position either with the use of bone cement or without its use. One of the limitations of cementless fixation is the risk of instability and loosening due to possible poor bone quality in elderly and elderly patients.
Procedure and Recovery
Like a total hip replacement, the femoral head of the bone is removed from the upper thigh and the shaft is cut to accept the stem of the partial implant. The device is inserted and the surgical opening is closed, usually with vacuum drains to remove any excess blood drainage.
Recovery can be problematic if you are elderly and have poor general health. Several patients manage to have a good quality of life again, however, almost the same number of people end up requiring attention for a long time due to problems related to age and health. In general, partial hip replacement surgery in west Delhi is a less complex operation than total hip replacement, and generally provides satisfactory results for less active elderly patients with less life expectancy. In the case of more active elderly patients with a longer life expectancy, a total hip replacement is preferred for displaced femoral neck fractures.
