An evaluation of the provocative tests for superior labral anterior posterior lesions.

Background: Although our understanding of superior labral anterior posterior lesions has grown, the physical diagnosis remains imperfect.

Study Design: Cohort study (diagnostic); Level of evidence, 2.

Purpose: To determine the most effective provocative maneuver with which to diagnose superior labral anterior posterior lesions.

An anatomic evaluation of the active compression test.

The goal of this study was to describe the anatomic relationships present during the active compression test. Four pairs of cadaveric shoulders were positioned to simulate the active compression test. The shoulders were embedded in polyurethane and evaluated in the axial and coronal planes with a planer.
