  • We are in private practice, we are not owned by a hospital or any physicians. I want to try and take back our profession – when you work for yourself you have to become a better clinician. Look at the work that has come from Austrailia – Diane Lee, Maitland, McConnell, Jim MeadowsIt is my goal today to make you a better clinician, and I challenge you to use that knowledge to reclaim our profession.
  • The health care bill just passed. I got up the next morning and log on to APTA web site to gain more information. I also get emails from the OPTA listserve. APTA members – this is my other soap box today, if you are not a member you need to join. The APTA is fighting for our rights. You need to get active in the OPTA, the PAC. Things are changing and you can either get involved and fight for your profession or your profession may drastically change.
  • Research – read your journals. CE courses – Clinical Expertise – clinical skill and formulated educationWhen I graduated, we tried to selective isolate the VMO for improving patellar mechanics – the literature has proven this ineffective.
  • Increaseing at a rate of 10% a year.
  • Sensitivity was 86% and specificity was 75% with a LR+ of 3.44
  • This was a low friction arthroplasty. Smaller femoral head 7/8 inch which has a decreased wear rate. However, it had a poor stability. This prosetesis used cement.Stems are typically made of titanium alloys or chrome cobalt – very strong and most biocompatible. New heads are ceramic or cobalt-chromium alloy.
  • FDA issued a warning. Recalled ceramic hip parts.
  • Most patients are diagnosed with snapping hip or psoas muscle strain or bursitis
  • This is a non-specific test – internal hip pathology (intra-capsular).
  • Feel end-feel. Should be capsular, not empty or painful.
  • Used to assess FAI – exactally like the shoulder impingement test. Same ball and socket joint. Always test this prior to having a patient stretch the piriformis muscle
  • Mitchell et all reported that the presence of hip pain during the FABER test was 88% sensitive for intra-articular hip pathology.
  • JOSPT July 2006
  • College of Rheumatology has criteria – so why did Childs develop a CPR?
  • X-ray will show joint space narrowing, osteophytes.
  • Do the exercise. How to correctly stretch the psoas.
  • Surgical approach used is one of the main determinates to rehabilitation. The posterior lateral approach is the most common, although as new techniques of minimally invasive THA are evolving, the anterior-lateral approach is becoming more common for younger, active patients.Posterior lateral approach – cuts posterior capsule and gluteus maximus – posterior dislocation.Anterior-lateral approach involves take-down of the gluteus medius, which can limit post-op weight bearing.
  • Surgery done in Europe for over 17 years. Birmingham Hip Resurfacing device was approved by the FDA in May 2006
  • Fracture rate at about 4% compared to 1% in THA. Have preserved the bone in the femur.
  • 2009 returned to cycling after his ban and finished 17th overall in the Tour of New Zeland.
  • FDA approved in 1997 – hyaluronan acid – extracellular matrix, contributes to cell proliferation.Molicular goo. Syovial fluid – increase the viscosity. Lubrication. Using in wound healing.

  • 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-A
    Acetabular 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 FAI
    Scour Test
    FADIR – anterior-superior labrum
    EABDER – posterior-inferior labrum
    Log Roll Test
  • 36. Scour Test
    The 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 Test
    The 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 Test
    The 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 Test
    The 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, is
    suggestive of intra-articular hip pathology.

    Twenty-one (29%) of the 72 subjects had radiographic evidence of hip OA.
