Sciatic nerve pain can originate from several factors which include; a disc herniation, sacroiliac joint dysfunction, degenerative joint disease, a tight piriformis, and more. Oatis, C. A., (2009). 1173185. The FADDIR Test (Flexion ADDuction Internal Rotation) accuracy for screening cam and pincer morphology ( Femoroacetabular Impingement) according to Nicola C Casartelli in his study 1: Sensitivity: 41-60 % Specificity: 47-52 % Another study by Burnett et al 2 found that Sensitivity of FADDIR Test was 95 % (Specificity not calculated). So they will fail FADIR. Forced passive hyperextension and external rotation can cause a painful anterior subluxation of the femoral head, in which the femoral head contacts the labrum , which is partially or completely torn (in hip dysplasia). Patient rests on the edge of table/plinth and raises one lower extremity towards their chest to position into hip flexion and is brought down to a supine position by the therapist. Translation: Having FAI bone shapes has no relationship to a positive or negative FADIR test. Using a test like this to convince someone to get surgery is misguided at best and irresponsible at worst. Put another away: you can have the FAI bone shapes, no hip pain, and have no pain on the FADIR. Step 4. The FAIR test is a sensitive and specific test for detection if irritation of the sciatic nerve by the piriformis. The apophysis of the superior iliac spine matures last and is susceptible to injury up to 25 years of age.2. Patients suspected of having FAI should have anteroposterior radiography of the pelvis and a modified Dunn view of the hip instead of standard hip radiography to assess for bony sources of impingement. Hip Physical Exam - Adult - Recon - Orthobullets Evaluation of the Patient with Hip Pain | AAFP Labral tears and early cartilage damage are now recognized as common sources of pain.2 Femoroacetabular impingement (FAI) is recognized as a common etiology of hip injury.3 Many joint-preserving operations, such as labral debridement, labral repair, and decompression of impinging bone lesions, are performed arthroscopically and have shown improvements in pain and function.4, FAI is the abutment between the proximal femur and the rim of the acetabulum. Passive hip ROM in internal rotation with neutral hip position had a . Somaybe the Flexion Abduction External Rotation hip pain test might be more accurate, thus giving us a fuller and more accurate picture of the cause of someone's hip pain!
