Total hip replacement in jaipur
- 1. TOTAL HIP REPLACEMENT IN JAIPUR What is a hip replacement surgery? Hip replacement, also called total hip arthroplasty, is a surgical procedure to replace a worn out or damaged hip with a prosthesis (an artificial joint). This surgery may be considered following a hip fracture (breaking of the bone) or for someone who has severe pain due to arthritis. Various types of arthritis may affect the hip joint. AVN arthritis affects young patients in India and may require THR at young age. Osteoarthritis, a degenerative joint disease that affects mostly middle- aged and older adults, may cause the breakdown of joint cartilage and adjacent bone in the hips. Rheumatoid arthritis, which causes inflammation of the synovial lining of the joint and results in excessive synovial fluid, may lead to severe pain and stiffness. Traumatic arthritis, arthritis due to injury, may also cause damage to the articular cartilage of the hip. The goal of hip replacement surgery is to replace the parts of the hip joint that have been damaged and to relieve hip pain that cannot be controlled by other treatments. Anatomy of the hip Joints are formed where bones meet. Most joints are mobile, allowing the bones to move without friction or discomfort. The hip joint is a ball-and-socket joint, which allows backward, forward, sideways, and rotating movements. The ball part of the hip joint is the head of the femur (thigh bone), and the acetabulum is the socket, a cup-like structure in the pelvis. The hip joint has significantly more bony contact and stability compared with other joints, such as the shoulder. A hip joint consists of the following: Femur: Thighbone or upper leg bone. Acetabulum: A socket or cuplike structure that holds the femur head. Cartilage: A type of tissue that covers the surface of a bone at a joint. Cartilage helps reduce the friction of movement within a joint. Synovial membrane: A tissue that lines the joint and seals it into a joint capsule. The synovial membrane secretes synovial fluid (a clear, sticky fluid) around the joint to lubricate it. Ligament: A type of tough, elastic connective tissue that surrounds the joint to give support and limits the joint’s movement. Tendon: A type of tough connective tissue that connects muscles to bones and helps to control movement of the joint.
- 2. Bursa: A fluid-filled sac located between bones, ligaments, or other adjacent structures that helps cushion joints. When you require THR? Hip replacement surgery is a treatment for pain and disability in the hip. The most common condition that results in the need for hip replacement surgery is Avascular Necrosis(AVN) and arthritis. it is characterized by the loss of joint cartilage in the hip. Damage to the cartilage and bones limits movement and may cause pain. People with severe pain due to degenerative joint disease may be unable to do normal activities that involve bending at the hip, such as walking or sitting, because they are painful. Other forms of arthritis, such as rheumatoid arthritis and arthritis that results from a hip injury, can also lead to degeneration of the hip joint. Hip replacement may also be used as a method of treating certain hip fractures. A fracture is a traumatic event that may result from a fall. Pain from a fracture is severe and walking or even moving the leg is difficult. If medical treatments are not satisfactory at controlling pain due to arthritis, hip replacement surgery may be an effective treatment. How to do THR? A hip replacement involves an incision several inches long over the hip joint. After soft tissue dissection and limb length markings head is dislocated and neck cut is performend than you get the view of socket and it is reamed to fit a appropriate size cup which can be fixed with screws depending on fixation and a lined is locked in the cup. Than femur is prepared by drill and rasp and appropriate trial is done if surgeon is happy the original implants are implanted. . The doctor will determine the best procedure for a person, based on that individual’s situation. What to know about implant? Unlike knee prosthesis hip prosthesis comes in lot of design and its right of every patient to understand about implant which they are going to receive. Generally we encourage our patients ot ask questions about implants. Three most important things are Fixation of Implant: weather cemented, uncemented or hybrid. A cemented prosthesis attaches to the bone with surgical cement. An uncemented prosthesis attaches to the bone with a porous surface onto which the bone grows to attach to the prosthesis. Sometimes, a combination of the 2 types is used to replace a hip than it is known as hybrid. Bearing Surface: different types of bearings are used: Metal on Poly, Metal on Metal, Ceramic on ceramic, Ceramic on poly. Metal on Metal Has been withdrawn by many companies due to metal ion side effects rest all other bearings are on use. For younger patients ceramics are better, Size of Head: Increase in head size brings more lieberty of motion but it also reduces the thickness of poly so a middle path has to followed.
- 3. Risks of the procedure? As with any surgical procedure, complications can occur. Some possible complications may include, but are not limited to, the following: • Bleeding • Infection • Blood clots in the legs or lungs • Dislocation • Changes in leg length or gait • Need for revision or additional hip surgery • Nerve injury resulting in weakness or numbness There may be other risks depending on your specific medical condition. Be sure to discuss any concerns with your doctor prior to the procedure.
