Scapular Morphology and Posterior Shoulder Stability: Biomechanical Evidence From an Advanced Cadaveric Shoulder Simulator.

Key Points

• This research aims to examine the relationship between scapular morphology and posterior shoulder stability using biomechanical evidence.
• Utilized an advanced cadaveric shoulder simulator to assess shoulder kinematics
• Evaluated the effect of scapular deformities on shoulder stability
• Conducted biomechanical tests to measure posterior shoulder kinematics
• Complete anatomic correction is necessary for restoring normal shoulder kinematics
• Observed significant differences in stability with and without deformity corrections
• Supported a comprehensive surgical approach for SPSL (superior posterior shoulder ligaments) treatment
