  • The female pelvis is lighter and thinner, wider in area, with a wider and flatter sacrum than a male's
  • The internal rotators of the hip include the tensor fascia latae, gluteus medius, and gluteus minimus
  • The assistive hip flexors include the pectineus, tensor fascia latae, sartorius, and rectus femoris.
  • adductor longus is responsible for hip flexion and adduction
  • adductor brevis is responsible for hip flexion and adduction
  • The pectineus is responsible for hip flexion and adduction
  • tensor fascia latae is responsible for hip internal rotation, flexion, and abduction
  • gluteus medius is responsible for hip internal rotation, flexion, and abduction
  • gluteus minimus is responsible for hip interal rotation, flexion, and abduction
  • sartorius is responsible for hip flexion, abduction, and external rotation
  • rectus femoris is responsible for hip flexion, abduction, and external rotation
  • iliopsoas is responsible for hip flexion and external rotation
  • piriformis is responsible for hip flexion, abduction, and external rotation
  • semimembranosus is responsible for hip extension and knee flexion
  • semitendinosus is responsible for hip extension and knee flexion
  • biceps femoris is responsible for hip extension and external rotation
  • gluteus maximus is responsible for hip extension and external rotation
  • adductor magnus is responsible for hip adduction and extension
  • gracilis is responsible for hip adduction and flexion
  • External rotation is done by rectus femoris, illiopsoas, sartorius, piriformis, gluteus maximus, gemellus superior, obturator internus, gemellus inferior, obturator externus, quadratus femoris, and biceps femoris.
  • The primary hip flexor is the illiopsoas which can be divided into the psoas major and iliacus
  • Hip complex is made up of the coxofemoral joint, sacroiliac joint, and the pubic symphysis
  • ligamentus support of the coxofemoral joint includes the iliofemoral, pubofemoral, and ischiofemoral ligaments
  • The ischiofemoral ligament resists adduction, hyperextension, and internal rotation
  • The head and neck of the femur make the angle of inclination and the angle of torsion
  • angle of inclination occurs in the frontal plane between an axis through the femoral head and neck and the longitudinal axis of the femoral shaft
  • angle of torsion occurs in the transverse plane between an axis through the femoral head and neck and an axis through the distal femoral condyles
  • With assistive hip flexions the tendosn cross anterior to the joint
  • with hip extensors tendons cross posterior to the joint
  • retroversion is a decrease in the angle of torsion influences the lateral rotation of the limb producing a toe out gait
  • anteversion is an increase in the angle of torsion that influences the medial rotation of the limb and produces a toe in gait
  • coxa valga has a neck shaft angle greater than 125 degrees which leads to supination of the foot and inversion ankle sprains
  • coxa valga lengthens the limb, decreases effectiveness ofabductors by decreasing distance between the femoral head and greater trochanter, reduces the load on the femoral neck, and increases the load on the femoral head
  • coxa vara is a neck-shaft angle less than 125 degrees which increases stress on the femoral neck
  • coxa vara shortens the limb, increases the effectiveness of the abductors by increasing the distance between the femoral head and greater trochanter, increases the load on the femoral neck, and reduces the load on the femoral head
  • Angle of inclination is affected by factors like congenital deformity, trauma, or disease may affect the angle
  • coxofemoral joint forms a diarthrodial ball and socket joint with 3 DOF
  • There are four bones tha make up the pelvic girdle the sacrum, coccyx, and the two hip bones that consist of the ilium, ischium, and pubis
  • The false pelvis is the bony area between the iliac crests and is superior to the pelvis inlet
  • pelvis inlet is a line between the lumbrosacral joint and the superior border of symphasis pubis
