A mobile superior labrum with intact cartilage is often a normal variant, not requiring surgical repair. Careful arthroscopic evaluation is key to differentiate this from a pathologic labral lesion.

Area of Science:

  • Orthopedic Surgery
  • Arthroscopy
  • Shoulder Anatomy

Background:

  • Differentiating superior labrum anterior posterior (SLAP) lesions from normal anatomic variants during arthroscopy can be challenging.
  • Mobile superior labrum with exposed articular cartilage on the superior glenoid tubercle is one such variant.

Purpose of the Study:

  • To systematically characterize superior biceps-labral configurations.
  • To demonstrate that a mobile superior labrum with exposed articular cartilage on the superior glenoid tubercle is a nonpathologic variant.

Main Methods:

  • Prospective, consecutive descriptive anatomic study.
  • Arthroscopic evaluation of 191 patients to quantify labral and articular cartilage dimensions.
  • 1-year clinical follow-up for a subgroup with identified mobile superior labrum.

Main Results:

  • 49 patients had a mobile labrum with intact articular cartilage on the supraglenoid tubercle and no injury.
  • Only 1 patient (2.0%) in this subgroup reported symptoms in the superior labrum-biceps origin region postoperatively.

Conclusions:

  • The indication for repairing a mobile superior glenoid labrum requires careful consideration of normal anatomic variability.
  • Mobile labral tissue overlying intact articular cartilage without evidence of trauma does not warrant surgical repair.
