The hip joint is a ball-and-socket joint that is formed where the thing bone (femur) meets the pelvis. The thigh bone has a ball-shaped end (femoral head) that fits into the sock formed by the acetabulum, which is part of the pelvis bone. The primary function of the hip joint is to support the weight of the body in both static (standing) and dynamic (walking or running) postures and influence balance.
Total hip replacement surgery, also called total hip arthroplasty, is a procedure where damaged bone and cartilage is removed from the hip joint and replaced with prosthetic components. Hip replacement surgery has the ability to relieve pain and restore normal function to the hip joint. (more...)
Arthroscopic surgery is a minimally invasive surgical procedure used to visualize, diagnose, and treat problems inside a joint. During an arthroscopic procedure, a surgeon uses pencil-sized instruments that contain a small lens and a lighting system that magnify and illuminate the joint. Images of the joint are displayed on monitors in the operating room, which allows the physician to see inside the joint. Arthroscopic hip procedures can be used to relieve pain, improve joint stability, repair damaged tendons or ligaments, and delay the onset of arthritis. (more...)
Articular cartilage is a thin, flexible, slippery tissue that covers the surface of both the ball (femoral head) and socket (acetabulum) portions of the joint. Articular cartilage creates a smooth, frictionless surface that enables the bones in the joint to glide smoothly against one another within the joint. It also plays an important role in weight-bearing, and helps with flexibility, extending, and rotating the hip joint. Articular cartilage does not possess a blood supply of its own. As a result, if the cartilage is damaged, it does not possess the ability to heal itself. (more...)
Hip impingement, or Femoroacetabular impingement (FAI), is a condition where the bones in the hip joint are abnormally shaped, meaning the bones do not fit together perfectly. This causes the hip bones to rub against each other and causes damage to the joint. (more...)
The labrum is a rim of cartilage that surrounds the hip joint. The labrum has two sides: one side attaches to the head of the thighbone (femur), the other side attaches to the hip socket (acetabulum). The labrum acts as a rubber seal, or gasket, that helps hold the thighbone securely within the hip socket. It also allows the body to maintain appropriate fluid pressure inside the joint. In addition, the labrum aides in shock absorption, joint lubrication, and stability. (more...)
