Gluteal Region consists of
Intergluteal cleft, Gluteal fold, gluteal sulcus
Efficient way to identify gluteal region
L4+ L5 interspace
Hip Joint movement
3 degrees of freedom
Gluteus maximus
Power extensor, innervated by inferior gluteal nerve, attaches directly to IT band
Gluteal bursae
Trochanteric, Ischial, and Gluteofemoral
Gluteus medius
Innervated by superior gluteal nerve, keeps pelvis level in midstance phase of gait
Gluteus minimus
Small, innervated by superior gluteal nerve, abduct hip, medially rotate hip, also similar to medius
Tensor fascia lata
second muscle attaches directly to IT band, flex, abduct, and internally rotate the hip
Iliotibial tract (IT band)
Attaches at Gerdy’s Tubercle (on tibia)
How many deep gluteal muscles
6 small muscles
Piriformis
Abduct flexed hip, laterally rotate extended hip
Quadratus Femoris
Laterally rotate hip
Obturator Internus
L shaped, lateral rotation of the hip, covers obturator foramen

Hip Joint ligaments
3 ligaments with 1 not too strong
Anterior ligaments of hip joint
Pubofemoral ligament and Iliofemoral ligament (Y shaped)
Posterior ligament of hip joint
Ischiofemoral ligament
Acetabular labrum
Transverse acetabular, synovial membrane, ligamentum teres and lunate surface
Popliteal Region (diamond)
Medially- Semimembranosus/ Gastrocnemius M
Laterally- Biceps femoris/ Gastrocnemius L
Popliteal Fossa Roof
Skin and Fascia
Popliteal Fossa Floor
Surface of femur, onlique ligament, popliteal fascia
Popliteal Fossa Vessels
Tibial Nerve, Common Fibular Nerve, Sural Nerve, Popliteal Artery and Vein
