Total hip Replacement
About the process:
A total hip replacement is a surgical procedure whereby the diseased cartilage and bone of the hip joint is surgically replaced with artificial materials. The normal hip joint is a ball and socket joint. The socket is a "cup-shaped" component of the pelvis called the acetabulum. The ball is the head of the thighbone (femur).
Total hip joint replacement involves surgical removal of the diseased ball and socket and replacing them with a metal (or ceramic) ball and stem inserted into the femur bone and an artificial plastic (or ceramic) cup socket. The metallic artificial ball and stem are referred to as the "femoral prosthesis" and the plastic cup socket is the "acetabular prosthesis." Upon inserting the prosthesis into the central core of the femur, it is fixed with a bony cement called methylmethacrylate.
Alternatively, a "cementless" prosthesis is used that has microscopic pores which allow bony ingrowths from the normal femur into the prosthesis stem. This "cementless" hip is felt to have a longer duration and is considered especially for younger patients. Total hip replacement is also referred to as total hip arthroplasty.
What is the procedure
Surgical procedures differ depending on the patient’s needs and the surgeon’s approach,
but generally the steps are as follows:
A hip replacement is performed for treatment of severe arthritis. Hip arthritis is a common cause of hip pain. Hip arthritis causes the normal smooth cartilage surface of the joint to wear out over time. As this cartilage is worn away, bone is exposed and normal movements of the hip become difficult. The hip joint is a ball-and-socket joint -- the ball rotates within the socket to allow hip movement. The ball and the socket are covered with a layer of smooth cartilage.
This cartilage allows for the hip joint to move freely. When the cartilage lining of the joint wears out, hip movements become stiff and painful. The another step of a hip replacement surgery is to remove the damaged cartilage and bone. to remove the worn-out ball the bone is cut to remove the femoral head. Once the arthritic ball is removed, the worn out socket can be addressed. Unlike the ball, this bone cannot be cut off -- the socket of the hip joint is part of the pelvis bone. Once the damaged bone has been removed from the acetabulum, the new socket of the hip replacement can be inserted. The socket of the pelvis is called the acetabulum, and the part of the hip replacement inserted into the socket is called the acetabular component. The acetabular component is held tightly in the pelvis by making the socket slightly smaller than the acetabular component, and wedging the implant into the bone.
The implant has a rough surface to allow bone to grow into the surface of the implant over time. The ball is supported with an implant inserted down the hollow centre of the thigh bone (femur). The femoral stem must be held tightly in the bone. Special tools are used to shape the centre of the thigh bone to accommodate the femoral stem. With the bone prepared to accept the stem of the hip replacement implant, the femoral stem is inserted. The stem can be held in the bone. When the bone is held with cement, the cement is inserted in a liquid form, and the stem is then placed. Within a few minutes, the cement permanently hardens to hold the implant fixed within the bone. When no cement is used, the implant is called "press-fit." This means that the implant is wedged tightly into the bone.
A rough surface covering the implant allows bone to grow into the implant over time. With the stem inserted down the centre of the thigh bone, the ball of the ball-and-socket hip joint can be inserted on top of the stem. A metal ball is tightly fit onto the top of the stem. Much of the design of a modern hip replacement implant is really just a way to hold the ball of the hip joint in the right position. There is a style of hip replacement where the ball is resurfaced rather than replaced, meaning there is less implanted material in the body--this style of hip replacement is called hip resurfacing surgery. With the socket, stem, and ball all inserted, the hip replacement can be placed in final position.
He's a Super Doctor I must say! I had severe Hip back pain which was not permitting me to stand or walk for more than 5 mins... I must say his experience and expertise in the field of ortho is immense. Today, only after a Hip surgery of treatment I'm back to my all normal activities. Very reasonable fees. Thank you Dr.UmeshShetty.- Bhajan Kaur
Excellent !Dr.Umesh is very friendly and transparent and explained total,Procedure in a very simple language satisfactorily.- Aditya Sharma
I visited so many doctors but no satisfaction in any treatment, one of my friend told me about axis hospital in andheri west, I met drumesh Shetty taked consultation about my problem he suggest me for hip replacement surgery. I gone through surgery he preformed very well now pain is seriously very less. Thanks for such lovely treatment I will recommend to you everyone. Thanks drumesh.- Jannifer Loza
Done very good job Dr umesh, very neat and clear rooms and OT, done surgery feel better to walk.- Suman Rani
Thanks for treatment given by dr Shetty, suggestion of surgery is best part. I was so scared about surgerys but you feel me safe. Pain free life thanks for giving me this life.- Pooj Asaklani
Hip replacement is a procedure in which a doctor surgically removes a painful hip joint of ten made from metal or plastic components.
- It can be under general anaesthesia as well as spinal anaesthesia.
- There is a stay of 6-8 days during the hip replacement procedure.
