THR stands for "Total Hip Replacement," which is a surgical procedure performed to remove a damaged or diseased hip joint and replace it with an artificial joint or prosthesis. It is typically done in patients who suffer from severe hip pain and limited mobility due to conditions such as osteoarthritis, rheumatoid arthritis, avascular necrosis, or hip fractures.
During a THR, the surgeon removes the damaged hip joint components, including the femoral head (top of the thigh bone) and the damaged socket (acetabulum). These are replaced with artificial prosthetic components made from metal, ceramic, or plastic materials. The prosthetic femoral head is attached to a stem, which is inserted into the thighbone, providing stability and allowing for movement. The socket is lined with a cup-shaped prosthetic, ensuring smooth articulation.
THR aims to relieve pain, restore hip joint function, and improve overall quality of life for individuals affected by hip joint issues. The procedure is usually performed under general anesthesia, and most patients require a hospital stay, followed by a period of rehabilitation to regain strength, mobility, and the ability to perform daily activities.
Risks associated with THR surgery include infection, blood clots, dislocation of the prosthetic joint, nerve damage, and implant loosening. However, with advancements in surgical techniques and implant materials, success rates for THR have greatly improved, resulting in reduced postoperative pain, quicker recovery times, and enhanced long-term outcomes for patients.
