Hip

Question 1

Ligaments

Answer 1

• Iliofemoral (strongest)
  – prevents excessive extension and plays a significant role in stabilizing and maintaining upright posture at hip, while limiting anterior translation
• ischiofemoral (weakest)
  – helps stabilize the hip in extension
• pubofemoral
• -prevents excessive abduction of femur and limits extension

Question 2

Ranges of motion and muscles according to movement

Answer 2

Flexion (110-120)- Psoas major, iliacus (assisted by: pectineus, rec fem, sartorius, adductors)

Extension (10-15)- Glut max, hamstrings

Adduction (30)- Adductor longus, brevis and magnus (assited by: pectineus and gracilis)

Abduction (30-50)- glut med and min (assisted by: TFL and sartorius)

Internal rotation (30-40)- TFL, glut med and min (assisted by: gracilis)

External rotation (40-60)- obturator internus and externus, gamellus superior and inferior, quadrates femoris (assisted by: piriformis, glut max and sartorius)

Any reduction in internal rotation can be either tight int rotators (glut med and max, TFL)- 1st option

2nd option- tight external rotators

this can work with other areas of the body as well
