Study Notes
Hip Pain Referral Patterns
- Hip pathology can lead to anterior thigh and/or medial knee pain which is related to L3 dermatome
- Common sources of referred pain in the hip joint region include:
- Spinal nerve roots L1, L2, L3, S1, S2
- Lumbar intervertebral and SI joints
- Example: Spinal Stenosis can refer pain to the hip
The Hip Joint
- The hip joint is also known as the Acetabular Joint and the Iliofemoral Joint
- It is a stable joint with a ball and socket structure
- The hip joint is synovial
- Stabilizing factors include:
- Weight-bearing joint
- Four strong ligaments
- Articular capsule extending from the rim of the acetabulum to the neck of the femur
- Acetabulum orientation and depth
- Fibrocartilaginous acetabular labrum attached to the margin of the acetabulum
- Orientation: Laterally, inferiorly, and anteriorly
Anatomical Definitions
- Hip: Coxa
- Knee: Genu
Hip Angles
- Understanding hip angles is important for diagnosing hip conditions
- Coxa vara:
- Decreased joint angle
- Can cause short leg if unilateral
- Coxa valga:
- Increased joint angle
- Can cause long leg if unilateral
- Genu valgum:
- Tibia oriented outward
- Genu varum:
- Tibia oriented inward
