Hip

Anatomy of the Hip

A bursa is a small sac of fluid that acts as a cushion between bones and the overlying soft tissues, reducing friction between the bone and muscles. There are four bursae associated with the hip. One, the trochanteric bursa, overlies the greater trochanter, which is the bony point of the hip that serves as a point of attachment for many of the muscles that move the hip joint. This is the largest bursa of the hip and the most common to cause symptoms. Another, called the iliopsoas bursa, is located on the groin side of the hip and lies between the bone the and iliopsoas tendon. The ischiogluteal, or simply ischial, bursa is deep in the pelvis below the hip joint and overlies the ischium of the pelvis. The gluteus medius bursa is near the trochanteric bursa and lies between the femur and the gluteus medius tendon. When any of these bursae become irritated and inflamed, the condition is commonly referred to as hip bursitis.

Gluteus Repair

The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur.

The gluteus maximus muscle is regarded as one of the strongest muscles in the human body. It is connected to the coccyx, or tailbone, as well as other surrounding bones. The gluteus maximus muscle is responsible for movement of the hip and thigh.

Labrum Repair

The hip is shaped like a ball-and-socket. The socket is called the acetabulum, and the ball is the femoral head, located at the top of the femur (leg bone). A hip labral tear is an injury to the labrum, the soft tissue that covers the acetabulum.

The labrum helps the femoral head move smoothly within the socket. It lets your hip move without problems or pain. It also serves as a seal, keeping the ball and socket together but not touching.

A labral tear of the hip is an injury of the hip labrum. This tough, crescent-shaped cartilage structure lines the rim of the hip socket (called the acetabulum), which is located in the pelvic bone. Also known as the acetabular labrum, this should not be confused with the labrum of the shoulder, which is a similar structure called the glenoid labrum.

Cam & Pincer Femoroacetabular Impingement

Femoroacetabular impingement (FAI) is a condition in which extra bone grows along one or both of the bones that form the hip joint, giving the bones an irregular shape. Because they do not fit together perfectly, the bones rub against each other during movement. Over time this friction can damage the joint, causing pain and limiting activity.

There are three types of FAI: pincer, cam, and combined impingement.

  • Pincer. This type of impingement occurs because extra bone extends out over the normal rim of the acetabulum. The labrum can be crushed under the prominent rim of the acetabulum.
  • Cam. In cam impingement the femoral head is not round and cannot rotate smoothly inside the acetabulum. A bump forms on the edge of the femoral head that grinds the cartilage inside the acetabulum.
  • Combined. Combined impingement just means that both the pincer and cam types are present.

Trochanteric Bursectomy

Our hips are marvels of flexibility. When we walk, they give us power and stability. When we jump, they can handle the impact. The hip joint is one of the largest and strongest joints in the human body.

But the hip can take a beating, and when that happens, we may feel pain.

One of the primary causes of hip pain is bursitis, which is an inflammation of the bursa. These fluid-filled sacs are found around the body and serve as cushions between bones and soft tissues such muscles, tendons, and skin.

Each hip has two major bursae. The outside point of the hip, which is called the greater trochanter, has a bursa called the trochanteric bursa..

When that outside hip bursa gets inflamed, you have trochanteric bursitis. Also known as greater trochanteric pain syndrome (GTPS), it is a common condition and easily treatable.
