What are the different steps of total hip resurfacing surgery?




Learning about total hip resurfacing surgery can help ease confusion and anxiety related to the surgical procedure. It involves removing the damaged surface of the affected hip joint and replacing that with an artificial joint.

The surgery is performed in the following steps

·         The affected hip is marked after checking vital signs of the patients. The vital signs including blood pressure, heart rate and body temperature have to be normal at the time of the surgery.

·         Anaesthesia is administered. It could be a general anaesthesia or regional/spinal anaesthesia for blocking sensation from the waist down.

·         Surgery starts with an incision made at the side of back of the affected hip. The incision exposes the bones at the hip joint by cutting deep through the skin and underlying muscles and soft tissues.

·         The hip-joint is dislocated by removing the head of femur from its socket (acetabulum) in the pelvis.

·         The affected hip is cut off with a bone saw.

·         The socket is prepared to receive an acetabular cup. A special tool called hemispheric reamer is used to prepare the socket. The tool grinds the socket to bring it into a predetermined shape.

·         An acetabular cup made of porous titanium metal is placed into the reshaped socket. The cup allows bone to grow into it overtime. Or the surgeon cold use bone cement to fix the cup into the socket.

·         The acetabular cup is fitted with a rounded liner to facilitate smooth movement within the new joint.

·         The femur bone is prepared and a prosthetic femoral stem is inserted into it.

·         A temporary prosthetic ball matching with the size of the acetabular cup is attached to the top of the femoral stem. The ball is used to check whether the joint has ease of motion.

·         The trial component is removed and the final ball is inserted into the socket.

·         X-rays are taken to make sure that the components are properly sized and positioned to prevent potential risk of dislocation.

·         The muscle and soft issues cut for surgery are repaired.

·         The skin cut with incision is stitched or stapled back for healing.

Total hip resurfacing surgery takes a minimum of 2 hours but much depends on the condition of patients. Post-surgery, patients are kept in a recovery room for couple of hours. Afterwards they are taken to hospital rooms for full recovery that takes a couple of days. But some hip replacement surgeries allows patients to leave the same day.

Total hip resurfacing surgery could be the answer to severe pain, swelling and stiffness in hip joint. The procedure involves trimming and capping of the femoral head that is the head of the thighbone with a smooth metal covering. To understand the difference between hip replacement and hip resurfacing in detail, you need to understanding the anatomy of a hip joint. The hip joint is made up of the head of the thighbone called femoral head and a round socket of the hip joint. The femoral head moves smoothly in the socket that is lined with cartilage that helps in smooth movement of the joint. The traditional total hip replacement involves replacing the femoral head and the damaged socket with artificial components made of metal, plastic or ceramic. But in resurfacing, the femoral head is cleaned of the damaged portion and only the cartilage within the socket is removed. A metal shell is placed in the socket to allow free movement of the joint. Advantages of r...
