Unit 4 Hip Flashcards
Hip Joint
- Femoral head & acetabulum articulation
- Bilateral
- Synovial joint
- Ball & socket
- High mobility (less mobility than shoulder)
Ligaments
- Iliofemoral
- Pubofemoral
- Ischiofemoral
Intracapsular Structures
- Acetabular labrum
- Ligament head of femur
- Transverse ligaments of acetabulum
Acetabular Labrum
- Thickening of fibrocartilage around acetabular
- Deepens joint socket
- Better contact with femur head
Ligament Head of Femur
- Obturator artery brancher
- Provide vasculature
- Attaches on fovea
Transverse Ligaments of Acetabulum
- Thickening of anterior aspect of acetabulum
- Reinforcement
Trochanteric
- Separate glutes from greater trochanter
- Prevent rubbing between gluteal muscles & bone
Greater Trochanter
- Lateral aspect of femur
Ischiogluteal
- Inferior aspect of ischial tuberosity
- Separate gluteus maximus & tuberosity
Hip Fracture
- Pull iliopsoas on lesser trochanter of femur
- External rotation
Hip Dislocation
- Posterior
- Traction of adductor group
- Internal rotation
Foot Drop with Hip Dislocation
- Inability to dorsiflex
- Weak eversion
- Foot hangs when raised off ground
- Long high steps
Femoral Neck Fracture
- Tear foveal & femoral arteries
- Avascular necrosis

- Inferior gluteal nerve & sciatic nerve
Lesser Sciatic Foramen Pathway
- Pudendal nerve
Femoral Triangle
- Femoral nerve, artery, vein
