Anatomy of the Hip
The hip joint is a ball-and-socket joint. The ball at the top of the thighbone, is referred as the femoral head whereas the socket which is the part of the pelvis is referred as acetabulum. The ball that rotates in the socket allows the movements of the leg. The cartilage which is the soft tissue covers the ball and the socket and helps them to glide together smoothly. In case if the cartilage wears down or is damaged then the bones scrapes together and become rough which leads to severe pain and makes it difficult for the leg to move. Hip Replacement Surgery is recommended in such cases where all other conservative treatments have failed to provide the patient with relief.
Hip replacement surgery is also referred as hip arthroplasty. This surgery provides patients with relief from the severe pain and restores the movement of people who have severe pain or stiffness in the hip. Mostly hip replacement surgery is performed to remedy hip arthritis. Hip arthritis is where the cartilage between the bones of the hip joint wears down which leads to scraping of the bones together causing more damage, stiffness, and pain. Arthritis of the hip can be very painful and can restricts person’s movements. Hip replacement surgery is also performed to fix injuries such as bone breaks, hips that grow incorrectly, and other conditions related to hip.
People who are suffering from the following are recommended with hip replacement surgery:-
- People who have severe and persistent pain in the hip.
- People who experience limited mobility.
- Stiffness in the hip joints.
- Failure of any medications and treatments.
- People suffering from rheumatoid arthritis which leads to inflammation in the joints.
- People with swelling in the hip joints.
- People who experience worsens walking condition.
- People who experience difficulty in rising from a seated position.
- People suffering from traumatic arthritis which damages the joint.
- People suffering from osteoarthritis which is a degenerative form of arthritis and is most common in older people.
The Hip Replacement Surgery is made up of the following four components:-
- The metal socket.
- The liner to help the ball move easily within the socket.
- Metal or ceramic ball to replace the femoral head.
- The metal rod which is used to stabilize the thigh bone to which the ball is attached.
There are different types of joint prosthesis. Most orthopedic surgeons use an uncemented joint prosthesis. This prosthesis allows the bone to grow into the prosthesis with time. Whereas cemented prosthesis is attached to the hip with bone cement for quicker adhesion. Uncemented joint prosthesis and cemented joint prosthesis varies in terms of recovery.
Before surgery:- Before surgery, the patients are recommended to lose some weight and are advised to stop taking any medications, including blood thinners. A day before the surgery the patients are told not to drink or eat anything and are given with IV. The IV allows the patient to receive fluids and medications at the time of surgery.
Procedure:- Hip replacement surgery can be performed with traditional approach or by minimally-invasive technique. The main difference between these two procedures is the size of the incision. The type of approach used depends on the condition of the patient.
It is performed under general anesthesia which helps the patients from feeling any pain during the surgery. The orthopedic surgeon makes an incision along the side of the hip and moves the muscles which are attached to the top of the thighbone so they could to expose the hip joint. Next, the surgeon removes the ball portion of the joint by cutting the thighbone. The artificial joint is then attached to the thighbone using either cement or a special material which allows the remaining bone to attach to the new joint.
The surgeon then prepares the surface of the hipbone by removing any damaged cartilage and attaches the replacement socket part to the hipbone. The new ball part of the thighbone is then inserted into the socket part of the hip. Next, the surgeon puts a drain so the remaining fluid is drained out and then reattached the muscles and closes the incision.
It is comparatively a new technique. The minimally-invasive technique involves 2 to 5 inches long incision. The same procedure as traditional surgery is performed through this small incision. Smaller incision leads to less loss of blood, faster recovery, less disturbance to tissues, less scarring and shorten hospital stays.
It is important to choose the right orthopedic surgeon for hip replacement surgery. Before choosing the orthopedic surgeon you should consider their experience, skills, the success rate of the surgeries performed, educational qualifications and most importantly you should compare the fees of various orthopedic surgeons before zeroing on the best one. India has some of the best and top orthopedic surgeon in the world. Orthopedic surgeon in India are highly skilled and qualified. Hip replacement surgery has a huge success rate in India. Patients from different countries visit India to undergo hip replacement surgery. Hip replacement surgery in India is available at the most affordable costs.
Total hip replacement surgery is a procedure which is utilized when all other options for treating a degenerated hip have failed to relieve symptoms & restore movement. A degenerated hip may get adversely affected by arthritis, or fracture to bone or other deteriorating medical conditions which can affect bone, joint or cartilage surrounding & supporting the hip joint of the patient. Surgical procedure for total hip replacement surgery begins with the doctor administering general anesthesia to the patient for operation. There are a number of types of prosthetic implants with varying materials & shapes which are used for replacing the damaged hip joint. However, all of them commonly involve two essential parts, the ball component which is made of strong ceramic or metal & which is highly polished for smooth movement along with a cup-like socket component made up of medical-grade ceramic, metal or plastic which usually has a soft outer shell. These prosthetic implant components are usually pressed-fit into the femoral head & the acetabulum so as to allow bones to grow around these implants & incorporate themselves into natural bone. Some artificial implants are also designed to fit into place with help of adhesive or surgical cement. However, type of prosthetic implant which will be chosen for a patient will depend upon the decision of the orthopedist based upon the strength & quality of the patient’s bone.
Hip replacement surgery is commonly required by patients suffering from chronic pain & instability in the hip joint, which is mainly due to various reasons including the following.
- Osteonecrosis – Also called ‘Avascular Necrosis’, this is usually caused due to injuries to hip, including dislocations & fractures, which affect the amount of blood being supplied to the femoral head. This irregular supply of blood to hip joint also causes weakness & brittleness in bones & which may also eventually result in arthritis.
- Congenital Hip Disorder – There are a number of childhood hip diseases which can cause hip arthritis when they come in adult age even among cases which were earlier treated during childhood. This is usually found to happen among cases where hips grow in abnormal ways or where joint surfaces experience friction.
- Rheumatoid Arthritis (RA) – RA is usually caused when fluid dispensing function of the synovial membrane is affected. This will eventually result in pain & loss of motion within the hip joint caused due to damage to the cushioning cartilage.
- Post-Traumatic Arthritis – This is a type of disorder which is caused when people experience severe injury or fractures damaging cartilage of the hip joints. This situation will also lead to pain & loss of movement in hip joints.
- What Happens During Hip Replacement Surgeries?
- Main purpose of hip replacement surgery is replacement of damaged components of hip joint, including both the femoral head & acetabulum, with artificial joint implants. This is normally done through a total joint replacement surgery which uses metal alloy or ceramic parts to replace the ball-like femoral head & for installing a newer surface in acetabulum within the pelvis. These implants are usually joined with existing healthy bone by using surgical cement or with help of a porous coating substance which helps bone to adhere to artificial implant in a natural fashion. Hip replacement surgeries are generally performed under influence of local or general anesthesia, depending upon the medical history & overall health of the patient. Following administration of anesthesia, orthopedists will make an incision at the side of hip & shift muscles, ligaments & tendons aside in order to approach the affected hip joint. After this, the surgeon will cut away the femoral head with help of a surgical saw & clean the acetabulum area of any debris bony pieces in cases of fractures. Attaching artificial implants to replace the femoral head & acetabulum socket is performed after which the operation site & the incision are stitched close.
- Are all total hip replacement implants the same?
- No, there are a variety of hip joint implants available nowadays. However, it is only the shape & composing material of these prosthetic implants which differ from one another, all of them in fact aim to provide a newer surface to bone-ends of hip joint which invariably try to restore movement within the damaged hip joint.
- How long does it take to perform a total hip replacement surgery?
- Total hip replacement surgery is a complex surgical intervention & may require anywhere between 4 – 6 hours of time. Orthopedic surgeons will first need to remove damaged portions of bones consisting of the femoral head & acetabulum region (hip joint) & subsequently fit the ceramic, plastic or metal prosthetic implant & also to align & restore them perfectly before stitching close the incision.
