Hips are an integral human body part and have their own significance. The wear and tear of hip joint affects its working and results in intense pain called hip arthritis. Hip replace surgery is performed to relieve hip pain and improve hip functionality. Femoral head of the hip bone is removed and replaced with an artificial one. The bone is cut during the surgery to place this ball shaped prosthetic femur head inside that later becomes the new socket of pelvis.
Steps of a Hip Replacement Surgery
After the diagnosis of hip arthritis, orthopedic physicians determine the area of surgery and the process vary as per the patient’s condition. However, these are the common steps of every hip replacement surgery and the process is considered as the most effective solution of arthritis.
Checkup and Anesthesia: Doctors note down blood pressure, heart beat, blood group, and body temperature before starting the surgery. General or regional anesthesia is given to block sensation.
Removal of Damage Cartilage: Surgeons make 10 inches incision to remove the damaged cartilage. During incision, skin and muscles are cut down to expose the bone. They remove damaged cartilage and take out the upper part of femur bone present in the hip socket. Femur bone is the actual part where the issue resides due to the bone-on-bone contact. The socket in the pelvis is also called acetabulum and surgeons use a saw to cut the arthritis femoral head.
Preparation of Acetabelum: After the removal of arthritic ball, surgeons prepare the acetabelum with the help of a tool reamer and scrap the unnecessary skin and cartilage to a make place for acetabular cup.
Placement of Acetabular Component: The cup is placed into the reshaped socket and placed tightly in the pelvis. For the perfect fit, the pelvis socket is made smaller than the acetabular component and it adheres with special perforated cement in order to give space for the bone growth.
Preparation of Femur: The next step is the preparation of femur bone in which surgeons insert prosthetic femoral stem in the femur bone. The stem is designed to hold the ball perfectly and shaped like a narrow tapered metal shaft so it excellently plays the role of femoral head.
Insertion of Final Ball into the Socket: A temporary ball is placed in the top of the stem to move the acetabulum cup and make sure that the joint can move easily. On getting satisfactory results from the temporary ball, permanent ball is inserted and doctors take the help of X-ray machine to check the size and position of the ball.
Skin Stitching: Stitching the skin is the last step of hip surgery. The muscles and the part of skin is precisely stitched and bandaged. Wedge willow is placed to between the legs to keep them apart from each other.
Usually, the patient has to spend a week in the hospital and doctors advise him/her about the range of motion precaution and weight bearing precautions to prevent any fatal issue later.
