33 Palpation Hip ASIS Iliac Crests PSIS Greater Trochanter Soft Tissue IT Band

34 What muscles do these movements? List out the muscles that do each movement: Abduction Adduction Hip Flexion Hip Extension External Rotation

35 Observation Symmetry- hips, pelvis tilt (anterior/posterior) –Lordosis or flat back Lower limb alignment –Knees, patella, feet –Genu Valgum/ Genu Varum Pelvic landmarks (ASIS, PSIS, iliac crest) Standing on one leg –Pubic symphysis pain or drop on one side Ambulation –Walking, sitting - pain will result in movement distortion

36 Observation Anteversion (A) and Retroversion (B) Think in terms of the Greater Trochanter

37 Observation Leg Length Discrepancy –Anatomical Actual bone length difference –Functional Rotation of pelvis Muscle tightness –1/8 inch or greater = discrepancy

38 Special Tests Fracture Range of Motion –Passive –Active –Resistive

39 Thigh Injuries Quadriceps Contusion –Mechanism Blow to quads. –Symptoms Pain Swelling Bruising Loss of function –Treatment RICE –Ice bent position

40 The red is hemorrhaging within the compartment Increased swelling = Increased pressure = decreased healing/ function If hemorrhage gets too large will have to do a compartment release which is done by cutting the fascia to allow the expansion

41 Thigh Injuries Myositis Ossificans Myo= muscle itis = irritation oss = bone –Mechanism Blow to thigh  Hemorrhage  hematoma –Symptoms Pain - Hard “bump” Musc weakness- Swelling Loss of function –Treatment At first can use Ultrasound Surgical Removal

42 Quad Compression Wrap –Start slightly above patella –Begin just like all other ACE wrapping techniques. –Continue up the thigh halfway overlapping alternating angling up and angling down. –Practice it!

43 Thigh Injuries Hamstring Strain –Mechanism Overloading of HS muscles Over stretching –Symptoms Pain- swelling- G2 or 3 = palpate deformity Loss of function- “popping” –Treatment RIC ROM stretching Compression wrap same as Quad Contusion

44 Hip Injuries Groin Strain –Straining of Adductors –Over stretching of the muscle Symptoms –Pain in medial hip –Pain referred to knee Treatment –RIC- light stretching –NSAIDs- Strengthening –ROM exercises- Compression wrap

45 Groin wrap Start with roll on lateral side of leg Start ACE at an angle –2 times around with “dog ear” Apply extra tension going medially as to pull the leg into ADduction. Continue your spica until out of wrap. - Athlete should fee leg being pulled in and slightly forward. ****Anytime doing a hip wrap you will pull in the direction that the injured muscles does.

46 Hip Flexor Strain Rectus Femoris/ Iliopsoas Strain -Often due to explosive activities (sprinting) -Symptoms -“Pop”- Loss of function -Pain -Treatment -Light stretches- rest -Compression wrap pulling forward -strengthening

47 Hip Special Tests Kendall / Thomas test –Positioning Athlete lies supine with ½ of femur off the table –Test Athlete hugs opposite knee to chest –Positive Knee Extends = Rectus Femoris tightness Hip Flexes = Hip Flexor Contracture

48

49 Hip Injuries Contusion (Hip Pointer) –Mechanism Blow to iliac –Symptoms Bruising Pain Loss of function –Treatment RICE

50 IT Band IT Band Tendonitis –Mechanism Repetitive friction over greater trochanter or lateral femoral condyle Pes cavus, Genu varum –Symptoms pain at greater trochanter or lateral femoral condyle Positive Ober and Nobles tests –Treatment Stretch tendon- Ice Strengthen Abductors- Rest

51 IT Band Tightness Noble’s Test –Position – athlete supine athlete’s knee is flexed to 90 degrees –Test – Pressure is applied to lateral femoral condyle while knee is extended –Positive – Pain at lateral femoral condyle IT Band Tendinitis

52 IT Band Tightness Ober’s –Position Athlete is lying on side opposite of affected side Tester is behind the athlete at the hip –Test Tester holds ankle and knee (flexed to 90) Tester allows knee to adduct. –Positive Pain or tightness No drop of the knee

53 Gluteus Medius and Adductor Weakness Trendelenburg –Position Patient stands with feet together –Test Tester stands behind the athlete Athlete lifts knee as to march –Positive Drop in the non weight bearing side PSIS/ Iliac Crest *Weakness in these muscle groups can lead to IT band tendonitis, bursitis, and other hip problems.

54 Hip Injuries Trochanteric Bursitis –Cause Excessive repetitive irritation at Greater Trochanter –Symptoms Hip instability Snapping sensation Pain/ inability to walk –Treatment ICE- Stretching NSAIDs- Strengthening Ultrasound (not the kind you see a baby with) Compression wrap Special Test - Range of Motion reproduces the pain

55 Hip Injuries Dislocated Hip –Mechanism Result of traumatic force –Signs and Symptoms Flexed, adducted and internally rotated hip Palpation reveals displaced femoral head posteriorly Other –Soft tissue, neurological damage and possible fx –Special Tests none –Management EMERGENCY ROOM! 2 weeks immobilization and crutch use for at least one month

56 Knee Observation Patellar positioning –Alta –Baja Knee Positioning –Genu varum –Genu valgum –Genu Recurvatum Swelling –Intracapsular –Extracapsular

57 Observation Patella Alta –High Patella tight quad muscles, places extra stress on patellar tendon, causes extra friction on Femoral condyles Patella Baja –Low Patella – shorter patellar tendon, causes extra friction on Femoral condyles

58 Soft Tissue of the Knee

59 Observation Genu Varum –Bow legged –Stresses lateral structures Genu Valgum –Knock kneed –Stresses medial structures Genu Recuvatum –Hyper-extended knees
