Hüftgelenksprothesen

Hüftgelenksprothesen, also known as artificial hips, are medical devices used to replace a damaged or diseased hip joint. The most common reason for hip replacement surgery is osteoarthritis, a degenerative joint disease that causes pain and stiffness. Other conditions that may necessitate a hip prosthesis include rheumatoid arthritis, avascular necrosis, and hip fractures.

The surgery typically involves removing the damaged femoral head (the ball part of the hip joint) and the acetabulum (the socket part). These are then replaced with artificial components made from materials like metal, plastic, or ceramic. The femoral component, often called a stem, is inserted into the hollowed-out femur, and a ball is attached to its top. The acetabular component is fitted into the pelvis, creating a new socket. These components are usually secured in place with bone cement or are designed to integrate directly with the bone over time.

There are different types of hip prostheses, including cemented and uncemented implants, as well as resurfacing options. The choice of prosthesis depends on factors such as the patient's age, bone quality, and overall health.

Following surgery, patients undergo a period of rehabilitation, including physical therapy, to regain strength, mobility, and function. While hip replacement surgery is highly successful in relieving pain and improving quality of life for many individuals, potential risks and complications can include infection, blood clots, dislocation of the prosthesis, and loosening of the implant over time. Regular follow-up appointments with a healthcare provider are important to monitor the long-term performance of the prosthesis.
