  1. Sports Medicine Camp The Thigh and Hip Muscles Anatomy, Injuries and Assessment

  2. Quadriceps Muscles • Vastus Medialis • Vastus Intermedius • Vastus Lateralis • Rectus Femoris

  3. Ely’s Test or Prone Knee Bend • Rectus Femoris tightness • Athlete prone • Passive knee flexion • Positive test indicated by hip flexion

  4. Quadriceps MMT • Manual Muscle Test • Athlete seated • Examiner apply resistance at lower leg

  5. Rectus Femoris Strain • Mechanism of Injury • Sudden stretch • Sudden contraction • Signs and Symptoms • Pain • Point tenderness • Spasm • Loss of function • Deformity • Treatment • RICE • NSAIDS • Modalities • Stretching • Strengthening

  6. Thigh Contusion

  7. Hamstrings Muscles • Medial side • Semitendinosus • Semimembranosus • Lateral side • Biceps Femoris Long Head • Biceps Femoris Short head

  8. Hamstrings MMT • Medial hamstrings • Semitendinosus • Semimembranosus • Internally rotate tibia • (foot points in) • Lateral Hamstring • Biceps Femoris • Externally rotate tibia • (foot points out)

  9. Hamstring Strains • Mechanism of Injury • Unknown • 1st Theory • Hamstrings contract same time as quadriceps • Deficiency in complementary action of opposing muscles • 2nd Theory • Quick change of function from • Role as knee stabilizer • To • Hip extensor • Possible reasons • Muscle fatigue • Faulty posture • Leg length discrepancy • Tight hamstrings • Improper form • Imbalance of strength between hamstrings • Hamstring strength ratio to quads normal 60 - 70 %

  10. Hamstring Strains • 1st Degree injury • Muscle soreness during movement • Due to muscle spasm rather then tearing of tissue • Fewer then 20% fibers torn • Point tenderness • Stiffness after cool down • 2nd Degree injury • Partial tear • Fewer then 70% fibers torn • Sudden snap or tear of muscle • Severe pain • Loss of function

  11. Hamstring Strains • 3rd Degree injury • Rupture of tendon • Tear of > 70% fibers • Severe swelling • Tenderness • Loss of function • Discoloration • Palpable mass or gap

  12. Hamstring Strains • Treatment • Grade 2 & 3 • Extremely conservative • RICE • Grade 2: 24 - 48 hrs. • Grade 3: 48 - 72 hrs. • Stretching • Strengthening • Emphasize eccentric exercise • Complications • Recurrent as result of • Inelastic fibrous scar tissue

  13. Hip Flexors • Iliopsoas • Psoas Major • Psoas Minor • Iliacus • MMT

  14. Thomas Test • Normal length of hip flexors • With low back flat • Posterior thigh touches table • Knee flexes approximately 80° • The pelvis is in 10 ° posterior tilt • Abnormal length of hip flexors • With low back flat • Posterior thigh does not touch table • Knee flexes < 80°

  15. Hip Flexor Support

  16. Adductor Muscles • Adductor Magnus • Adductor Longus • Adductor Brevis • Pectineus • Gracilis • MMT Adduction • Athlete sidelying • Examiner supports top leg • Give resistance above knee joint

  17. Adductor Support 8-4

  18. Hip Pointer • Mechanism of injury • Direct impact • Signs and Symptoms • One of the most handicapping injuries • Immediate pain • Muscle spasm • Transitory paralysis • Inability to • rotate trunk • Flex thigh • Discoloration • Swelling • Treatment • PRICE • Bed rest as needed • Crutches as needed • ROM exercises • Strength exercises • Severe cases MD referral 21-34
