Normal Anatomy of the Hip joint
The hip joint is composed of a ball and socket joint. The femoral head (ball) is the top of the femur (thigh bone) and the acetabulum (part of the pelvis) is the socket. These surfaces are both covered by articular cartilage, which is a specialized lining allowing smooth pain free motion of the joint. Damage to this lining result in arthritis.
Hip pain, one of the common symptoms patients complain of, may not always be felt precisely over the hip joint. Pain may be felt in and around the hip joint and the cause for pain is multifactorial. The exact position of your hip pain suggests the probable cause or underlying condition causing pain.
Femoro Acetabular Impingement (FAI)
Femoroacetabular impingement (FAI) is a condition where there is too much friction in the hip joint from bony irregularities causing pain and decreased range of hip motion. The femoral head and acetabulum rub against each other creating damage and pain to the hip joint.
The hip plays an important role in supporting the upper body weight while standing, walking and running, and hip stability is crucial for these functions. The femur (thigh bone) and acetabulum (hip bone) join to form the hip joint, while the labrum (tissue rim that seals the hip joint) and the ligaments lining the hip capsule maintain the stability of the hip. Injury or damage to these structures can lead to a condition called hip instability.
Hip Cartilage Injuries
Labrum is a ring of strong fibro-cartilaginous tissue lining around the socket of the hip joint. Labrum serves many functions where it acts as shock absorber, lubricates the joint, and distributes the pressure equally.
Proximal Hamstring Repairs
Hamstring injuries are common in athletes who participate in sports activities such as track, soccer, and basketball that involve running. The three hamstring muscles namely semitendinosus, semimembranosus and biceps femoris are at the back of the thigh and helps you bend (flex) your knee and extend your leg.
Gluteus Medius Repairs
Gluteus medius is one of 3 muscles in the buttocks and is situated on the outer surface of the hip. The function of the gluteus medius is to assist with pelvis stability, hip abduction, along with internal and external rotation of the hip. Tears of the gluteus medius usually occur where the tendon inserts at the greater trochanter, causing lateral hip pain.
Hip Chondral Injuries
The hip joint is one of the largest weight-bearing joints in the body, formed by the thigh bone or femur and the acetabulum of the pelvis. It is a ball and socket joint with the head of the femur as the ball and the pelvic acetabulum forming the socket. The joint surface is covered by a smooth articular cartilage which acts as a cushion and enables smooth movements of the joint. A chondral injury refers to an injury of the articular cartilage, covering the joint.
Snapping Hip Syndromes
The hip is an important joint that helps us walk, run and jump. The ball-and-socket joint in the hip is formed between the round end of the femur (thighbone) and the cup-shaped socket of the acetabulum (part of the hip bone).
