Hip muscles

HIP MUSCLES

1. MAXIMUM GLUTTE

Medial Insertion: Posterior gluteal line of the iliac, sacrum, coccyx, and sacrotuberous ligament
Lateral Insertion: Ileotibial tract of fascia lata and femoral gluteal tuberosity
Innervation: Lower Gluteus Nerve (L5 & #8211; S2)
Action: Hip Extension and Lateral Rotation

2. Average Glute

Superior Insertion: External aspect of the ileum between the iliac crest, posterior and anterior gluteal line
Lower Insertion: Greater Exchange
Innervation: Superior Gluteus Nerve (L4 & #8211; S1)
Action: Abduction and Medial Rotation of the Thigh

3. MINIMUM GLUTE

Superior Insertion: Iliac wing (between anterior and inferior gluteal line)
Lower Insertion: Greater Exchange
Innervation: Superior Gluteus Nerve (L4 & #8211; S1)
Action: Abduction and Medial Rotation of the Thigh. Anterior fibers perform Hip Flexion

4. FIRMING

Medial Insertion: Pelvic surface of sacrum and margin of major sciatic notch
Lateral Insertion: Greater Exchange
Innervation: Nerve for the piriformis muscle (S2)

5. TOP TWIN

Medial Insertion: Ischial Spine
Lateral Insertion: Greater trochanter
Innervation: Nerve for the superior twin muscle (L5 & #8211; S2)
Action: Thigh Lateral Rotation

6. INTERNAL SHUTTER

Medial Insertion: Inner face of obturator membrane and ischium
Lateral Insertion: Greater trochanter and trochanteric femoral fossa
Innervation: Nerve for the internal obturator muscle (L5 & #8211; S2)
Action: Thigh Lateral Rotation

7. LOWER TWIN

Medial Insertion: Ischial Tuberosity
Lateral Insertion: Greater Exchange
Innervation: Nerve for the inferior twin muscle and femoral square (L4 & #8211; S1)
Action: Thigh Lateral Rotation

8. EXTERNAL SHUTTER

Medial Insertion: Branches of pubis and ischium and external surface of obturator membrane
Lateral Insertion: Femoral Trochanteric Fossa
Innervation: Nerve for the external obturator muscle (L3 & #8211; L4)
Action: Thigh Lateral Rotation

9. FEMORAL SQUARE

Medial Insertion: Ischial Tuberosity
Lateral Insertion: Intertrochanteric Crest
Innervation: Nerve for femoral square and inferior twin muscle (L4 & #8211; S1)
Action: Lateral Rotation and Thigh Adduction
