1. Chapter 18 Hip
Hip bone – aka os coxae; ilium, ischium & pubis

2. Joint Structure and Motions
Flexion/extension/hyperextension
Abduction/adduction
Medial/lateral rotation
Triaxial; 3 degrees of freedom
Flexion 120; extension – return from flexion 120; hyperextension 15
Abduction – 45; adduction – 25
Medial/lateral rotation – 45 each

3. Bones and Landmarks
Ilium
Iliac fossa
Iliac crest
ASIS
AIIS
PSIS
PIIS

4. Bones and Landmarks

Lateral condyle
Medial condyle
Adductor tubercle
Linea aspera

8. Ligaments and Other Structures
Joint capsule
Iliofemoral ligament
Pubofemoral ligament
Ischiofemoral ligament
Ligamentum teres
Acetabular labrum
Inguinal ligament
Iliotibial band
Iliofemoral – Y ligament; Ligament of Bigelow; limits hyperextension; anterior
Pubofemoral – anterior; limits hyperextension & abduction; medial & inferior
Ischiofemoral – posterior; limits hyperextension & IR
Ligamentum teres – blood supply
Inguinal ligament – separates abdominal wall from thigh

14. Common Hip Pathologies
Congenital hip dislocation
Legg-Calvé-Perthes disease
Slipped capital femoral epiphysis
Coxa valga/coxa vara
Anteversion/retroversion
Osteoarthritis
Congenital hip dislocation – dysplasia; shallow acetabulum
Legg Calve Perthes – necrosis of femoral head; children 5-10;
Coxa Valga - > 125; longer LE; hip adducted
Coxa Vara - < 125; shorter LE; pelvic drop
Anteversion - > 15-25; toe in; IR
Retroversion - < 15-25; toe out; ER

15. Common Hip Pathologies
Hip fracture
Iliotibial band syndrome
Trochanteric bursitis
Hamstring strain
Hip fracture – intertrochanteric or femoral
Hip Pointer – contusion of iliac crest/ASIS
