höftlederna

Höftlederna, also known as the hip joints, are ball-and-socket joints that connect the femur (thigh bone) to the pelvis. Each hip joint consists of the head of the femur fitting into a cup-shaped socket in the pelvis called the acetabulum. This structure allows for a wide range of motion, including flexion, extension, abduction, adduction, rotation, and circumduction. The hip joints are crucial for weight-bearing, locomotion, and maintaining balance.

The stability of the hip joint is maintained by a strong capsule, ligaments, and surrounding muscles. The articular cartilage lining the bones reduces friction and allows for smooth movement. The hip joint is a weight-bearing joint, meaning it supports a significant portion of the body's weight during standing, walking, and running.

Common conditions affecting the hip joints include osteoarthritis, a degenerative joint disease, and hip fractures, which are often caused by falls, especially in older individuals. Hip dysplasia is a condition where the acetabulum does not fully cover the femoral head, leading to instability and potential dislocation. Pain and limited mobility are common symptoms associated with hip joint problems. Treatment options vary depending on the condition and can include medication, physical therapy, injections, or surgery such as hip replacement.
