  19. Kinematics and Major Muscle Actions (cont’d) • Hip flexors • Iliopsoas, pectineus, rectus femoris, sartorius, and tensor fascia latae • Two-joint muscles • Rectus femoris—active during hip flexion and knee extension • Sartorius—active during hip flexion and knee extension

  20. Kinematics and Major Muscle Actions (cont’d) • Hip extensors • Gluteus maximus and hamstrings (biceps femoris, semitendinosus, and semimembranosus) • Hamstrings—two-joint; hip extension and knee flexion

  21. Kinematics and Major Muscle Actions (cont’d) • Hip abductors • Gluteus medius, gluteus minimus • Active in stabilizing pelvis during single-leg support and during support phase of walking and running • Hip adductors • Adductor longus, adductor brevis, and adductor magnus

  22. Kinematics and Major Muscle Actions (cont’d) • Lateral rotators • Piriformis, gemellus superior, gemellus inferior, obturator internus, obturator externus, and quadratus femoris • Lateral rotation of femur of swinging leg accommodates lateral rotation of pelvis during stride

  23. Kinematics and Major Muscle Actions (cont’d) • Medial rotators • Gluteus minimus • Tensor fascia latae, semitendinosus, semimembranosus, gluteus medius, and adductors

  24. Kinematics and Major Muscle Actions (cont’d)

  25. Kinematics and Major Muscle Actions (cont’d) • Hip joint – movement in 3 planes • Sagittal • Flexion and extension • Frontal • Abduction and adduction • Transverse • Medial rotation and lateral rotation of the femur

  26. Injury Prevention • Physical conditioning • Flexibility • Strength • Protective equipment • Hip joint well protected but iliac and pelvis need protection • Thigh • Shoe selection • Cushion forces

  27. Contusions • Hip pointer • MOI:direct blow to iliac crest • S&S • Any trunk movement is painful (incl. coughing, laughing, & breathing) • Immediate pain, discoloration, spasm, and loss of function • Unable to rotate trunk or laterally flex the trunk toward injured side.

  28. Contusions (cont’d) • Hip pointer (cont’d) • S&S (cont’d) • Any trunk movement is painful • Extreme tenderness • Abdominal muscle spasm may be present • Severe injury – unable to walk or bear weight, even with crutches

  29. Contusions (cont’d) • Hip pointer (cont’d) • Management • Standard acute; rest; protect with hard-shell pad for return to activity • Severe pain over iliac crest – physician referral

  30. Contusions (cont’d) • Quadriceps contusion • MOI: direct blow • Common – anterolateral thigh • S&S • Pain may be extensive immediately after impact

  31. Contusions (cont’d) • Quadriceps contusion (cont’d) • S&S (cont’d) • Grade I • Mild pain and swelling • Able to walk without a limp • Passive flexion beyond 90° – painful; resisted knee extension may cause less discomfort.

  32. Contusions (cont’d) • Quadriceps contusion (cont’d) • S&S (cont’d) • Grade II • Can flex the knee between 45 and 90° • Walks with a noticeable limp • Grade III • Unable to bear weight or fully flex the knee.

  33. Contusions (cont’d) • Quadriceps Contusion (cont’d) • Management: • Standard acute; with knee in maximum flexion • Hard-shell pad for return to activity • Physician referral if S&S persist >48 hours

  34. Contusions (cont’d) • Quadriceps contusion (cont’d) Management of a quadriceps contusion

  35. Contusions (cont’d) • Myositisossificans • Myositis ossificans • Develops secondary to single significant blow or repetitive blows to same area • Evident on radiograph 3–4 weeks after injury

  36. Contusions (cont’d) • Myositis ossificans (cont’d) • S&S • Warm, firm, swollen thigh; 2–4 cm larger • Palpable, painful mass may limit passive knee flexion to 20–30° • Active quadriceps contractions and straight leg raises—difficult • Management: standard acute; physician referral

  37. Bursitis • Bursa of the hips • MOI • Excessive friction orshear forces due to overuse • Greater trochanteric bursitis • Influence of Q-angle

  38. Bursitis (cont’d) • Greater trochanteric bursitis • S&S • Burning or aching over or posterior to greater trochanter • Aggravated with: • Hip abduction against resistance • Hip flexion and extension on weight bearing

  39. Bursitis (cont’d) • Iliopsoas bursitis • Pain medial and anterior to joint; cannot be easily palpated •  pain with passive hip rotation; resisted hip flexion, abduction, and external rotation

  40. Bursitis (cont’d) • Ischial bursitis • Pain aggravated by prolonged sitting and uphill running, • Point tenderness directly over ischial tuberosity •  pain with passive and resisted hip extension

  41. Bursitis (cont’d) • Bursitis management • Do not permit to continue activity until seen by a physician • Suggest cold to decrease pain and inflammation

  42. Bursitis (cont’d) • Snapping hip syndrome • Can result from chronic bursitis • S&S • Snapping sensation heard or felt during hip motion, especially with lateral rotation and flexion while balancing on one leg • Iliopsoas bursa affected—snapping in medial groin

  43. Bursitis (cont’d) • Snapping hip syndrome (cont’d) • Management • Do not permit to continue activity until seen by a physician • Suggest cold to decrease pain and inflammation

  44. Hip Sprains and Dislocations • MOI • Violent twisting actions • With hip and knee flexed to 90°, force through shaft of femur • S&S • Mild/moderate: pain with internal rotation • Severe: intense pain; inability to move hip • Position of flexion and internal rotation

  45. Hip Sprains and Dislocations (cont’d) • Management • Mild/moderate—standard acute; physician referral • Severe—activate EMS; immobilize in position found – do not move; monitor and treat for shock

  46. Hip Dislocations Hip dislocations

  47. Strains • Quadriceps • Typically rectus femoris • S&S • Grade I • Normal gait, but tightness in the anterior thigh • Pain with passive knee flexion beyond 90°

  48. Strains (cont’d) • Quadriceps (cont’d) • S&S (cont’d) • Grade II • Snapping or tearing sensation, followed by immediate pain and loss of function. • Knee held in extension – protection • Pain with passive knee flexion; Pain & weakness with knee extension

  49. Strains (cont’d) • Quadriceps (cont’d) • S&S (cont’d) • Grade III strains • Extreme pain • Ambulation not possible • Defect in the muscle may be visible • Resisted knee extension not possible; ROM is severely limited

  50. Strains (cont’d) • Hamstrings • Initial swing—flex knee; late swing—eccentrically contract to decelerate knee extension and re-extend hip in prep for stance phase • Overemphasis on stretching without strengthening • Additional risk factors (Box 14.2) • Strength imbalance
