HIP ORTHO
Orthopedic tests of the hip, supported by peer-reviewed research, offer clinicians a reliable means of diagnosing various hip pathologies such as femoroacetabular impingement (FAI), labral tears, and muscular imbalances. Below are descriptions of key orthopedic tests for the hip from journal articles, with in-text references and a reference list.
1. FABER Test (Flexion, Abduction, External Rotation)
The FABER test, or Patrick’s test, is commonly used to assess intra-articular hip pathology and sacroiliac joint dysfunction. The patient lies supine with the hip flexed, abducted, and externally rotated, forming a figure-four position. The examiner presses down on the knee while stabilizing the opposite hip. Pain in the groin may indicate hip pathology, while pain in the sacroiliac region suggests SI joint dysfunction. A study by Martin et al. (2008) validated the FABER test’s ability to detect intra-articular hip conditions, especially when used with imaging.
2. FADIR Test (Flexion, Adduction, Internal Rotation)
The FADIR test is designed to identify femoroacetabular impingement (FAI) and labral tears. The patient lies supine while the examiner flexes the hip to 90 degrees, adducts it, and then internally rotates the hip. Pain in the anterior hip region suggests FAI or labral pathology. Reiman et al. (2015) reported that the FADIR test is highly sensitive for detecting FAI, making it a valuable tool for ruling in hip impingement.
3. Log Roll Test
The log roll test is used to assess for ligamentous laxity and labral tears in the hip. The patient lies supine while the examiner passively rolls the leg into internal and external rotation. Increased external rotation or the presence of a clicking sensation may indicate hip joint laxity or a labral tear. A study by Martin and Sekiya (2008) highlighted the effectiveness of the log roll test for detecting ligamentous laxity in patients with labral pathology.
4. Hip Scour Test
The Hip Scour test is used to evaluate intra-articular pathology such as osteoarthritis or labral tears. The patient lies supine, and the examiner flexes the hip to 90 degrees and applies axial pressure through the femur while internally and externally rotating the leg. Pain, clicking, or a grinding sensation during the movement may indicate joint pathology. Emary and Taylor (2010) found this test to be helpful in detecting degenerative conditions of the hip joint.
5. Trendelenburg Test
The Trendelenburg test assesses the strength of the gluteus medius muscle, which is critical for maintaining pelvic stability. The patient is asked to stand on one leg while the examiner observes the pelvis. If the pelvis drops on the unsupported side, it indicates weakness in the gluteus medius on the standing leg. Hardcastle and Nade (1985) emphasized the clinical value of this test in identifying gluteus medius weakness, which can lead to compensatory hip pain.
6. Thomas Test
The Thomas test is used to evaluate hip flexor tightness, particularly in the iliopsoas muscle. The patient lies supine and pulls one knee to the chest while allowing the other leg to remain flat on the table. If the extended leg lifts off the table, this indicates tightness in the hip flexors. Harvey (1998) supported the use of the Thomas test for diagnosing iliopsoas tightness, which may contribute to hip and lower back discomfort.
7. Ober’s Test
Ober’s test evaluates the tightness of the iliotibial (IT) band. The patient lies on their side with the lower leg bent for stability. The examiner abducts and extends the top leg, then allows it to passively drop into adduction. If the leg does not drop below midline, this indicates IT band tightness. Fredericson and Wolf (2005) showed that Ober’s test is a reliable method for detecting IT band syndrome, especially in athletes.
8. Piriformis Test
The piriformis test helps identify piriformis syndrome, a condition where the piriformis muscle compresses the sciatic nerve. The patient lies on their side with the hip and knee flexed. The examiner applies downward pressure on the knee while stabilizing the pelvis. Pain in the buttock or radiating down the leg suggests piriformis syndrome. Fishman et al. (2002) demonstrated that the piriformis test is effective in diagnosing piriformis syndrome, particularly when combined with other clinical findings.
