Changes in Scapular Function, Shoulder Strength, and Range of Motion Occur After Latarjet Procedure

Area of Science:

• Orthopaedic Surgery
• Biomechanics
• Sports Medicine

Background:

• The Latarjet procedure is a common surgical intervention for shoulder instability.
• Understanding the anatomic and biomechanical consequences is crucial for patient outcomes.

Purpose of the Study:

• To conduct a literature review on the anatomic alterations following the Latarjet procedure.
• To identify research gaps concerning functional implications and potential complications.

Main Methods:

• A systematic search of English-language studies on open Latarjet procedure outcomes.
• Screening of titles and abstracts, followed by full-text review of eligible articles.
• Data extraction included study design, population, methods, and key findings related to anatomic changes.

Main Results:

• The Latarjet procedure alters scapular position and may increase humeral head translation.
• Subscapularis split technique shows better internal rotation strength than tenotomy.
• Limited evidence exists on the functional impact of humeral head translation and capsular repair effects on external rotation.
• Nerve changes (musculocutaneous) appear to have limited clinical significance.

Conclusions:

• The Latarjet procedure induces notable anatomic and biomechanical shoulder changes.
• Future research should focus on scapular and elbow function, rotator cuff integrity, and osteoarthritis development post-procedure.
