The lateral rotator group is a group of six small muscles of the hip which all externally (laterally) rotate the femur in the hip joint.It consists of the following muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus.
As the hip flexes, the tension in the ligament is reduced and the amount of possible rotations in the hip joint is increased, which permits the pelvis to tilt backwards into its sitting angle. Lateral rotation and adduction in the hip joint is controlled by the strong transversal part, while the descending part limits medial rotation. [4]
Kaltenborn test or Hip Lag Sign for hip abductor function. To perform the Kaltenborn test, the patient has to lie in a lateral, neutral position with the affected leg being on top. The examiner then positions one arm under this leg to have good hold and control over the relaxed extremity, whereas the other hand stabilizes the pelvis.
External rotation (lateral rotation or extorsion) is rotation away from the center of the body, [22] carried out by external rotators. Internal and external rotators make up the rotator cuff , a group of muscles that help to stabilize the shoulder joint .
External rotation and extension of the hip joint, supports the extended knee through the iliotibial tract, chief antigravity muscle in sitting and abduction of the hip: Antagonist: Iliacus, psoas major and psoas minor: Identifiers; Latin: musculus glutaeus maximus: TA98: A04.7.02.006: TA2: 2598: FMA: 22314: Anatomical terms of muscle
FABER or Patrick test - To identify if pain may come from the sacroiliac joint during flexion, abduction, and external rotation, the clinician externally rotates the hip while the patient lies supine. Then, downward pressure is applied to the medial knee stressing both the hip and sacroiliac joint. [1] [2] [4]
The pectineus muscle is the most anterior adductor of the hip. The muscle's primary action is hip flexion; it also produces adduction and external rotation of the hip. It can be classified in the medial compartment of thigh [2] (when the function is emphasized) or the anterior compartment of thigh (when the nerve is emphasized). [3]
In vertebrate anatomy, the hip, or coxa [1] (pl.: coxae) in medical terminology, refers to either an anatomical region or a joint on the outer (lateral) side of the pelvis.. The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and lateral to the obturator foramen, with muscle tendons and soft tissues overlying the greater trochanter of the femur.
