Partial hip replacement, also called hip hemiarthroplasty, is a surgical procedure where only the femoral head (the ball) of the damaged hip joint is replaced. The acetabulum (the socket) is not replaced. By contrast, in total hip replacement, the acetabulum is replaced with a prosthetic. Broken and fractured hips – traumatic hip injury ...
In cases of a broken hip (fractured neck of femur) where the fracture cannot be pinned, your surgeon may perform a partial hip replacement. In these cases, the broken femoral head is replaced with a prosthesis which is just a ball and stem. The acetabulum is still in good condition and is no implant is placed there.
The hip joint is a simple ball and socket shape. The ball is at the top of your thigh bone and the socket is in the side of your pelvic bone. Depending on the amount of damage caused by arthritis, a surgeon may recommend hip resurfacing or total hip replacement surgery to a patient.
From a clinical standpoint, a surgeon will consider total hip surgery for a patient when alternative methods such as changes in activities, mild painkillers, and physiotherapy have been exhausted. Depending on the age of the patient and the damage to the tissue, the surgeon may suggest arthroscopy or a partial hip replacement before a total hip ...
The hip is the body’s second largest weight-bearing joint (after the knee). It is a ball and socket joint at the juncture of the leg and pelvis. The rounded head of the femur (thighbone) forms the ball, which fits into the acetabulum (a cup-shaped socket in the pelvis). Ligaments connect the ball to the socket and usually provide tremendous ...
The short answer is hip implants generally last between 15 and 20 years but often much longer. There are many still active patients whose hip prostheses were put in as long as 30-40 years ago. The important factors to consider are the condition of the patient (osteoporosis or other bone conditions), general physical health and ability to ...
It should be noted however, that recovery time for a total hip replacement can differ vastly from patient to patient. Some patients may recover in 6 to 8 months; while others may require a longer recovery time. Health care providers refer to a patient’s hip replacement surgery recovery time and rehab into two segments – short-term and long ...
Advantages of Partial Knee Replacement. In appropriate cases, the advantages of partial knee replacement over total knee replacement include a smaller scar, marginally quicker recovery, marginally less post-op pain, and less blood loss. Some recipients maintain that a partial knee replacement feels more natural and provides better range-of-motion.
During a hip replacement, the head of the femur is removed. A metal stem is inserted and a ball fitted on top of the stem to replace the head of the femur. A metal liner or cup is then placed in the acetabulum and may be fixed with 2 or 3 screws. Into this is placed a plastic, metal or ceramic liner. The ball then fits into the cup, creating ...
Total Hip Replacement Femoral Stem Options. The acetabular socket into which the ball fits can be made of metal, ultra-high molecular-weight polyethylene (plastic), or a combination of polyethylene backed by metal. The materials to be used in your implant will be chosen by your surgeon, based on many factors, including the criteria below.
