This document provides an overview of a physical therapy course on total hip rehabilitation. The course objectives are to understand hip surgery and exercises, describe hip biomechanics, and effectively progress patients through rehabilitation. The schedule covers topics like evidence-based practice, anatomy, exercises, and outcome measures. Recent advances in hip rehabilitation include smaller incisions, reduced hospital stays, and early mobilization leading to better short-term outcomes. Assessment tools for hip function include the Lower Extremity Function Scale and Harris Hip Score.

12. OSTEOARTHRITISIn US, 100 Billion Health Care $ by 2020Progressive loss of articular cartilage with variable subchondral bone loss.Prevalence – 10 to 25% in adults age 55 and older.43 Million people in USStandard of care is THA

13. Total Hip ArthroplastyThe most common surgical procedure for end-stage hip osteoarthritis.Primary reason for surgery is pain which interferes with ambulation.

14. American College of RheumatologyClassification Hip OACluster 1Pain in the hip< 115 hip flexion< 15 IRCluster 2Pain with IR< 60 minutes morning stiffness> 50 yrs. oldCurrent guidelines focus on pharmacological and surgical management

15. X-RayDemonstrate loss of joint space, osteophytes and sclerosis.Dysplasiatears are more common in individuals with acetabular dysplasia.

16. In US, between 1990 and 2002, THA rose from 119,000 to 193,000 annually.62% increase600,000 THA Procedures Performed Annually

17. Total Hip ArthroplastyThe first joint replacement, a total hip arthroplasty, was performed in 1936.Most widely performed orthopedic procedure performed on adults.In 2008, the average hospital and physician charge for a THA totaled $ 45,000.

33. Femoroacetabular Impingement (FAI)Contact between the femoral head-neck junction and the acetabular rim.Impingement occurs with the combined movement of hip flexion, adduction, and internal rotation.

34. Precursor to early hip O-AAcetabular labral pathology secondary to femoroacetabular impingement (FAI)Acetabular labral pathology is frequently present in highly active individuals 20-40 yo.Gradual on-set with repetitive microtrauma.

35. Diagnosis of FAIScour TestFADIR – anterior-superior labrumEABDER – posterior-inferior labrumLog Roll Test

36. Scour TestThe examiner moves the patient’s hip through a range of motion from hip flexion and adduction to hip extension and abduction, while adding a compressive force through the hip joint as well as movement into hip internal and external rotation. The test is considered positive if there is a reproduction in hip pain and/or intraarticular joint clicking.

37. Log Roll TestThe examiner passively moves the patient’s lower extremity through the maximal available range of hip external (A) and internal rotation (B).Eliciting a clicking or popping sensation may indicate an acetabular labral tear, while increased total range of motion when compared to the opposite side may indicate ligament or capsular laxity

38. Impingement TestThe examiner passively moves the patient’s lower extremity into a position of hip flexion, adduction, and internal rotation. A positive test is reflected by increased hip or groin pain.

39. FABER TestThe examiner passively positions the testing limb in a position of hip flexion, abduction, and external rotation. The examiner assesses the perpendicular distance from the knee on the tested lower extremity to the table. A decrease in this distance or pain, when compared to the uninvolved side, issuggestive of intra-articular hip pathology.

Clinical Prediction RuleChilds September 2008Loss of IR< 15 degrees Loss of Flexion< 115 degrees(+) Scour Test(+) FABER Test(+) Hip Flexion Test Twenty-one (29%) of the 72 subjects had radiographic evidence of hip OA. A clinical prediction rule consisting of 5 examination variables was identified. If at least 4 of 5 variables were present, the positive LR was equal to 24.395% confidence interval: 4.4-142.1, increasing the probability of hip OA to 91%.
