Labral Tears

Tears of the acetabular labrum — types and treatment

Labral tears are very common and are usually caused by stresses placed on the labrum by abnormal bone morphology. A labral tear should not be the primary diagnosis — it is usually expected in all painful hips. Labral tears can heal with repair if the causative factors are treated.

Key Principle

A labral tear should not be the primary diagnosis — it is usually expected in all painful hips. Treating the causative morphology is essential.

Classification

1

Chondrolabral Separation

From cam impingement, acute subluxation, or dislocation.

2

Intrasubstance Tears

From pincer impingement.

3

Dysplastic Labral Tears

Dysplastic hips tear a hypertrophied labrum that can avulse adjacent acetabular articular cartilage, or have a bone fragment attached to the torn labrum (rim fracture), or a combination producing an inside-out tear.

Flap tears and radial tears are additional descriptive subtypes.
