The hip ball fits into a liner. Together, the ball and liner create the new joint. The liner is inserted into a metal shell that in turn is anchored to your pelvis. But there are a number of different approaches a surgeon can take, depending on her analysis of your particular case.
Hip replacement may be recommended for patients suffering from:
(A) Hip pain that has failed to respond to conservative therapy.
(B) Loose hip prosthesis.
(C) Hip joint tumors.
(D) Hip osteoarthritis or arthritis confirmed by X-ray.
Total hip replacement prosthesis consists of three parts:
(a) A cup that replaces the hip socket.
(b) A ball that will replace the fractured head of the thigh bone.
(c) A metal stem that is attached to the shaft of the thing bone to add stability to the prosthesis.
Hip Joint Replacement
Hip replacement surgery is an operation used to replace the damaged ball-and-socket with new and durable artificial synthetic parts that mimic the ball-and-socket. The procedure should relieve a painful hip joint, making walking easier.
Who undergo hip replacement surgery?
Although there is no age limit for hip replacement, generally patients between 50-80 years of age undergo the surgery. Today, the improved artificial parts can withstand more pressure and last longer, which is good news for young patients going for the hip replacement surgery. Teenagers with juvenile arthritis to the elderly patients with degenerative arthritis have successfully undergone hip replacement surgeries.
What is the hip replacement surgery procedure?
In the hip replacement surgery, also known as hip arthroplasty, the damaged bone and cartilage is replaced with the prosthetic components. These are made up of either plastic, ceramic, or metal spacer that allow smooth gliding surface motion. The implants are joined with the bones either using cement or without cement.
To choose from cemented or uncemented surgery is the decision that your doctor would discuss with you based on your reports, before the surgery. The operation lasts for about one to two hours. Some surgeons have begun to make smaller incisions for shorter wound recovery time and a smaller scar. Also called minimally invasive surgery, it may take longer time compared to traditional hip replacement.
There are two types of hip replacement surgeries:
Total Hip Replacement
Total Hip replacement surgery is a safe and effective procedure that can relieve your pain, increase motion, and help you get back to enjoying normal, everyday activities. The bone surfaces of the ball and socket are covered with articular cartilage, a smooth tissue that cushions the ends of the bones and enables them to move easily. Then an artificial joint is attached to the thighbone using either cement or a special material that allows the remaining bone to attach to the new joint.
Partial Hip Replacement
Surgeons normally perform partial hip replacement in case of fracture/injury, where only femoral head would be replaced. Your orthopedic surgeon would recommend you the type of hip replacement based on your medical reports.
Do hip replacement surgeries have any complications?
Like any other surgery, this surgery also has its share of complications but occur very rare. Less than 2% cases report problems such as blood clot, infection, or loosening/wearing of joints. Although uncommon, before the surgery, you should discuss the ways to reduce the risks with your orthopedic surgeon. All these are taken care of by your surgeon by continuous monitoring, medications, and precautionary measures.
Recovery after the hip replacement surgery
Hip replacement surgery recovery within one to two days after the surgery, you may be able to sit, stand, and walk with help of assistance. Your stay in the hospital post-operation may be for three to six days and your wound staples would be removed within 15 days after the surgery.
Getting back to normal routine activities for each patient may vary from three to six months depending upon case-to-case basis. If your job requires prolonged standing, walking, or other physical activity, your doctor would advise you to delay return to work. Light duty or office work or minimal physical activities can be resumed in about three months.
