Hip Replacement
The hip joints are the largest ball-and-socket joints in the human body. The hip socket and the head of the thigh bone (femur head) are connected by the hip joint. Half of the femoral head is surrounded by the hip socket. This provides the hip joint with good, bony stability. This stability is additionally supported by a joint capsule and cartilage seam called as labrum.
Along with the lower back muscles, the hip muscles in the hip and thigh area provide stabilization, absorb shocks and bring the knees and feet into correct alignment. With the lower back and knees, the hips literally play a pivotal role in nearly all physical activities.
With every step we take, our hip joints must bear loads of several times our body weight. When climbing stairs, for instance, the hips bear load of almost three times our body weight. While the load is particularly high in sports such as running or jumping, it is much lower in others, i.e. cycling or swimming.
Hip Joint Arthritis
Arthritis is a progressive wearing down of the articular cartilage, which may occur naturally due to aging but may also be caused by injuries or congenital malformations, or infections. In the process, the joint surfaces are gradually destroyed and typical complaints such as pain during the first few steps after inaction, night pains as well as restricted movement begin to arise.
Total Hip Replacement (THR) or Total Hip Arthroplasty (THA)
It is a surgical procedure that replaces worn or damaged parts of your hip joint. The diseased joint's surfaces are removed and replaced with a mechanical, artificial joint known as a prosthesis. This surgery can help you get rid of the pain and stiffness in your hip joint.
The femur and pelvic parts of your new hip prosthesis are made of metals and Ultra-high-molecular-weight polyethylene . The cup replaces your pelvic hip socket's worn hip socket. The ball is used to replace the worn end of your thigh bone (femur). The ball is connected to a stem that is inserted into your femur. The cup and stem are sometimes cemented in place with special bone cement, or the metals may have a porous surface into which bone grows to create a tight fit. The prosthesis has a lifespan of 15 to 20 years. However, it may become worn and loose over time, necessitating a revision hip replacement.
