THE HIP
| Term | Definition |
|---|---|
| Hip Flexion | Moving leg forward toward the face |
| Hip Extension | Moving the leg backwards |
| Hip Abduction | Moving leg away from body |
| Hip Adduction | Moving leg toward the body |
| External Rotation of Hip | Rotate upper leg/knee away from body |
| Internal rotation of HIp | Rotate upper leg/knee inward toward body |
| Circumduction of Hip | Rotation of leg in a circular pattern |
| Ligaments of the Hip | Illiofemoral, Ischiofemoral, Pubofemoral - all are thick, strong, twisted around head of femur |
| Plexus | A group of nerves which innervate a specific region of the body and originate from a specific region of the spinal cord |
| Femoral Nerve | Primary nerve of anterior thigh |
| Sciatic Nerve | Primary nerve of posterior thigh |
| Femoral Artery | Primary artery of lower extremity; can take a pulse on this blood vessel in the crease of your leg. |
| Dorsalis Pedis | Artery on top of foot; can take a pulse there |
| Ice with knee in Flexion | Primary treatment for quadriceps contusion/strain. |
| Strain | "pulled muscle"; injury that a quad contusion usually merges into |
| Chronic hip injuries | bursitis, snapping hip syndrome, tendonitis, stress fractures; usually seen in sports requiring repetitive motions such as running, gymnastics, dance, etc |
| Hip dislocation | usually posterior; usually caused by forceful hip flexion & internal rotation, with possible adduction; requires transport for reduction due to risk of damaging femur and increasing chance of vascular disorders. |
| Apophysis | soft, cartilaginous like area of bone where tendons attach to flat bones |
| Myositis Ossificans | Growth of bone-like material within muscle tissue. Caused by severe contusion/tearing of muscle tissue, followed by use of heat/friction too soon. |
| Hip Stress fracture | Commonly seen in femoral neck, pubis and proximal 1/3 of femur |
| Hip Pointer | Extremely painful bone contusion at ASIS |
| Legg-Calve-Perthes Disease | Avascular necrosis seen in children |
| Avascular Necrosis | Degeneration of the femoral head due to impaired blood supply to the bone tissue; often caused by repetitive trauma to the joint or a singular severe trauma to the hip (dislocation) |
| Snapping Hip Syndrome | Chronic bursitis; snapping/popping sensation over lateral hip; can be caused by repeated hip flexion/extension with internal or external rotation of the hip |
| Pelvis Fracture | Significant injury due to potential blood loss and potential shock; requires 911 call; usually due to significant trauma such as auto accidents |
| Anterior muscles of the Hip | Rectus femoris, illiacus, psoas major/minor, sartorius |
| Medial muscles of the Hip | Adductor magnus, adductor longus, adductor brevis, pectinius, gracilis |
| Lateral muscles of the hip | Tensor Fascia/IT band, gluteus minimus (can be also included posteriorly!) |
| Posterior muscles of the Hip | Gluteus maximus, gluteus minimus, gluteus medius, piriformis, semimembranosis, semitendonosis, biceps femoris long head |
