Please can someone explain in easy to understand language the difference between a fair test and a comparative test? Special Test: FABER Test (Figure 4 Test) PURPOSE:Testing for hip joint pathology, lumbar and SI (sacroiliac) pathologies, and psoas muscle shortness/spasm. The hip is a ball-and-socket joint in which the articular surfaces of the femoral head and the acetabulum are lined with articular cartilage (Figure 1). Byrd JW, Hunt J, Patient demographics, diagnostic imaging, and summary measures (eg sensitivity, specificity, etc.) The FAIR test has been shown to have good sensitivity and specificity of 0.84 and 0.83 respectively. Ganz R, It usually progresses gradually and can injure the labrum and the articular cartilage of the hip, potentially limiting patients' ability to exercise and causing pain with daily activities.5 FAI is a common cause of labral injury, and FAI with or without labral injury has been identified as an early cause of hip osteoarthritis.3,5,6, Some persons are predisposed to impingement by bony abnormalities, which can be congenital or developmental. femoral and acetabular deformity common in general population and often asymptomatic. FAI is the abutment between the proximal femur and the rim of the acetabulum. Martin RL, 05th December 2014 22:34 by Anonymous (not verified) 6. Am Fam Physician.
