Faber Test

What is the Faber test?

The Flexion Abduction External Rotation Test (FABER) is used to assess sacroiliac joint pathology. The patient is supine on the examination table and is asked to place one foot on the opposite knee (hip flexion to maintain abduction in external rotation). These three movements are combined to help diagnose hip conditions in a clinical test that causes pain. Pelvic and sacroiliac region. While supporting the pelvis with one hand, the physician pressed hard on the bent knee, supporting the pelvis on the opposite upper iliac spine.

The positive finding of pain in the sacroiliac joint of the leg being tested for this. One study found that the sensitivity was 54%-66% and the specificity was 51%-62%

Importance of the Faber test

When grouped together, this test can be very helpful in identifying people with sacroiliac joint dysfunction. See the Lumbar / Sacroiliac Spine Homepage for the group. Try the sacroiliac joint because as the horizontal abduction force passes through the thigh, tight soft tissues transfer energy to the sacroiliac joint.

Therefore, this test may indicate pathology in the hip or sacroiliac joint. The test also assesses the hip as forces are transferred through the joint. The flexion, abduction, and external rotation position, when combined with high pressure, stresses the thigh-acetabular joint and produces pain if irritated.

Clinically relevant anatomy of Faber Test

The accent of the hip is a true ball joint and diatroidal lace.

It is formed from the head of the thigh when expressed with the acetabulum of the pelvis. This joint serves as the main link between the lower limb and the trunk and generally acts as a closed kinematic chain. So designed for stability and weight-bearing, rather than large-scale movement.

The movements available at the hip joint are flexion, extension, abduction, flexion, internal rotation, and external rotation. The ligaments in the hip joint work to increase stability. They can be divided into two groups: intracapsular and extracapsular.

Purpose of Faber test

The Faber test is used to detect the presence of hip pathology by attempting to reproduce pain in the hip, pelvic spine, or sacroiliac region. The test is a passive screening tool for musculoskeletal pathologies such as hip, lumbar spine, or sacroiliac joint dysfunction, or iliopsoas spasm.

The test also assesses the hip as forces are transferred through the joint. The flexion, abduction, and external rotation position, when combined with high pressure, stresses the thigh-acetabular joint and produces pain if irritated.

In combination with other tests, such as the range of motion and the hip quadrant test, the Fabers are a useful tool to guide clinicians in prescribing more images for patients with persistent hip or groin pain.

When the Faber tests, it provides very useful information to identify those who suffer from sacroiliac joint dysfunction. Try the sacroiliac joint because as the horizontal abduction force passes through the thigh, the soft tissues in tension transfer energy to the sacroiliac joint. Therefore, this test may indicate pathology in the hip or sacroiliac joint.

How Faber test perform?

The patient’s examined leg is placed in the position, where the knee is bent and placed on the knee opposite the ankle. The hip is flexed, abducted, and placed in external rotation (hence the name Faber). The examiner applies force in the posterior direction against the middle knee of the bent leg toward the tabletop. A positive test is done when pain occurs in the groin or buttocks.

Due to the forces going through the hip joint, the patient will have pain if there is pathology in the hip. The patient was placed in the supine position. The leg is held in one position (the hip is bent and abducted with the lateral ankle close to the knee. A few smaller amplitude oscillations can be used to make a positive test that reproduces the patient’s pain or range limitations of movement.
