🦴Assessing the Hip — Clinical Tests and Red Flags

Hip · The hip is a deep, stable ball-and-socket joint that bears several times body weight during walking and running, making it a common site of both overuse pain and degenerative change.

Quick answers

What causes hip pain in older adults?

Osteoarthritis is among the most common causes of hip pain after middle age, involving gradual breakdown of the joint's cartilage and associated changes in the surrounding bone and soft tissue.

What is greater trochanteric pain syndrome?

Greater trochanteric pain syndrome describes pain at the outer hip related to irritation of the gluteal tendons or the nearby bursa, often mistaken in the past for bursitis alone.

What is femoroacetabular impingement?

Femoroacetabular impingement describes abnormal contact between the femoral head and the hip socket during certain movements, related to subtle variations in bone shape, which can contribute to groin pain and reduced range of motion in some individuals.

Does hip osteoarthritis always require surgery?

Many cases of hip osteoarthritis are managed for years with exercise, weight management, and activity modification; joint replacement is typically considered when conservative measures no longer provide adequate relief.

Can weak glute muscles cause hip pain?

Reduced strength or endurance in the gluteal muscles is commonly associated with several hip and even knee conditions, since these muscles are central to controlling pelvis and leg alignment during walking and running.

What is a hip labral tear?

A hip labral tear is damage to the ring of cartilage that deepens the hip socket, which can occur from trauma, repetitive impingement, or gradual wear, and may contribute to pain, clicking, or a sense of instability.

Start with this section - Tests & assessment

Hip assessment typically begins with observation of gait and posture, followed by active and passive range of motion testing to identify restriction patterns common in osteoarthritis or impingement.

A series of special tests then helps localize symptoms to the joint, labrum, or specific tendons, while a brief screen rules out referred pain from the lower back or, rarely, more serious pathology.

Assessment tests

Screen for joint or sacroiliac involvement

FABER (Patrick's) test

Positioning the hip in flexion, abduction, and external rotation and noting pain location helps distinguish hip joint pain from sacroiliac joint pain.

Provoke femoroacetabular impingement

FADIR test

Bringing the hip into flexion, adduction, and internal rotation reproduces anterior groin pain in impingement or labral pathology.

Assess gluteal muscle function

Trendelenburg test

Standing on one leg and observing whether the opposite pelvis drops assesses the strength and control of the gluteus medius.

Assess iliopsoas involvement

Resisted hip flexion test

Resisting active hip flexion from a seated position can reproduce pain associated with iliopsoas-related groin pain.

Detect joint restriction

Passive range-of-motion screen

Comparing passive internal and external rotation to the opposite side helps identify the capsular restriction typical of osteoarthritis.

Warning signs

These warrant prompt clinical review rather than unsupervised exercise progression.

Inability to bear weight after trauma

A sudden inability to bear weight on the leg following a fall, particularly in older adults, raises concern for hip fracture and warrants urgent evaluation.

Fever with hip pain

Hip pain accompanied by fever raises concern for joint infection, especially in children, and requires prompt medical assessment.

Unexplained weight loss with deep hip or groin pain

These features can occasionally indicate a non-musculoskeletal cause and should be assessed by a physician.

Sudden severe pain with a snap or pop

A sudden pop or snap followed by severe pain and inability to continue activity may indicate a significant muscle or tendon tear requiring evaluation.

This combination of gait observation, joint-specific tests, and muscle function screening allows clinicians to distinguish joint, tendon, and muscular causes of hip pain in most straightforward cases.
