Introduction[edit | edit source]
Hip abduction is the movement of the leg away from the midline of the body. This action is used daily eg when we step to the side, get out of bed; get out of the car. We also use it in walking to stop unsupported leg in walking falling "into space".
The Hip abductor muscle group are located laterally on the thigh are the hip abductors.
- The primary hip abductor muscles include the gluteus medius, gluteus minimus, and tensor fasciae latae.
- The secondary hip abductors include the piriformis, sartorius, and superior fibers of the gluteus maximus.[1]
Many hip and knee problems arise due to weal hip abductors. Hip abduction strengthening exercises help to prevent and treat pain in the hips and knees[2].
Function[edit | edit source]
The hip abductor muscles contribute to various actions, including pelvic stabilization during walking and running; abduction and rotation at the hip joint[3].
The hip abductor muscles stabilize the hip within the frontal plane during the single-limb support phase of walking. High demand is placed on the hip abductors occurs with walking. eg The right abductor muscles must work when the right leg is in the single-limb support phase of gait, as the left limb is swinging forward. The right hip abductors must supply an adequate contraction force to keep the pelvis from dropping down to the L. Weakness of these muscles results in an unstable pelvis while walking or while attempting to stand on one leg[1].
Sub Heading[edit | edit source]
Gluteus medius is the prime mover of abduction at hip joint. It is located on the lateral aspect of the upper buttock, below the iliac crest. The superior muscle is broad with the muscle narrowing towards its insertional tendon giving it a fan-shape. The anterior portion of Gluteus medius abducts and assists in flexion and medial rotation of hip. The posterior portion of Gluteus medius abducts and assists in extension and lateral rotation of hip.[4]
Gluteus minimus muscle is the smallest one of the three gluteal muscles, it lies deep to the gluteus medius muscle. The gluteus minimus is similiar to the gluteus medius in function, structure, nerve and blood supply. The gluteus minimus acts in synergy with the gluteus medius to abduct and internally rotate the thigh, and contributes to the stabilization of the hip and pelvis[5].
The tensor fasciae latae (TFL) is a muscle of the proximal anterolateral thigh that lies between the superficial and deep fibres of the iliotibial (IT) band. The TFL works in conjunction with the gluteus maximus, gluteus medius, and gluteus minimus in a wide variety of hip movements, including flexion, abduction, and internal rotation.The TFL is most important clinically for assisting in pelvis stability while standing and walking[6].
The secondary hip abductors include the
sartorius, and
superior fibers of the gluteus maximus
