The hip joint is a ball-and-socket joint composed of the femur head and a socket, which is part of the pelvis. The labrum is a cartilage ring on the socket part of the hip joint that helps keep joint fluid inside to ensure frictionless hip motion and alignment during movement. A labral tear of the hip is an injury to the labrum. The extent of the damage can vary. Sometimes, the hip labrum can have mini tears or fray at the edges, usually caused by gradual wear and tear. In other cases, a section of the labrum can separate or get torn away from the socket bone. These types of injuries are usually due to trauma. There are conservative hip labral tear tests to determine the type of injury. The Injury Medical Chiropractic and Functional Medicine Clinic team can help. 

Symptoms

Symptoms are similar regardless of the type of tear, but where they are felt depends on whether the tear is in the front or the back. Common symptoms include:

• Hip stiffness
• Limited range of motion
• A clicking or locking sensation in the hip joint when moving.
• Pain in the hip, groin, or buttocks, especially when walking or running.
• Night discomfort and pain symptoms when sleeping.
• Some tears can cause no symptoms and can go unnoticed for years.

Hip Labral Tear Tests

A hip labral tear can occur anywhere along the labrum. They can be described as anterior or posterior, depending on which part of the joint is affected:

• Anterior hip labral tears: The most common type of hip labral tear. These tears occur on the front of the hip joint.
• Posterior hip labral tears: This type appears on the back of the hip joint.

Tests

The most common hip labral tear tests include:

• The Hip Impingement Test
• The Straight Leg Raise Test
• The FABER Test – stands for Flexion, Abduction, and External Rotation.
• The THIRD Test –  stands for the Hip Internal Rotation with Distraction.

Hip Impingement Tests

There are two types of hip impingement tests.

Anterior Hip Impingement

• This test involves the patient lying on their back with their knee bent at 90 degrees and then rotated inward towards the body.
• If there is pain, the test is considered positive.

Posterior Hip Impingement

• This test involves the patient lying on their back with their hip extended and their knee flexed and bent at 90 degrees.
• The leg is then rotated outward away from the body.
• If it results in pain or apprehension, it is considered positive.

Straight Leg Raise Test

This test is used on various medical conditions that involve back pain.

• The test begins with the patient sitting or lying down.
• On the unaffected side, the range of motion is examined.
• Then the hip is flexed while the knee is straight on both legs.
• The patient may be asked to flex the neck or extend the foot to stretch nerves.

The FABER Test

It stands for Flexion, Abduction, and External Rotation.

• The test begins with the patient lying on their back with their legs straight.
• The affected leg is placed in a figure four position.
• The physician will then apply incremental downward pressure to the bent knee.
• If there is hip or groin pain, the test is positive.

The THIRD Test

This stands for – the Hip Internal Rotation with Distraction

• The test begins with the patient lying on their back.
• The patient then flexes their knee to 90 degrees and turns it inward around 10 degrees.
• The hip is then rotated inward with downward pressure on the hip joint.
• The maneuver is repeated with the joint slightly distracted/pulled apart.
• It is considered positive if the pain is present when the hip is rotated and diminished pain when distracted and rotated.

Chiropractic Treatment

Chiropractic treatment involves hip adjustments to realign the bones around the hip and up through the spine, soft tissue massage therapy to relax the muscles around the pelvis and thigh, targeted flexibility exercises to restore range of motion, motor control exercises, and strengthening exercises to correct muscular imbalances.
