Arthroscopic Bennett Lesion Resection: A Novel Technique

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Arthroscopy

Background:

• Bennett lesion is ossification of the posterior inferior glenohumeral ligament complex.
• Often asymptomatic, it can cause pain and affect throwing ability in athletes.
• Common in elite throwers, potentially caused by posterior joint traction or impingement.

Purpose of the Study:

• To describe and evaluate an arthroscopic technique for treating symptomatic Bennett lesions.
• To assess the efficacy and patient outcomes of this surgical approach.

Main Methods:

• Arthroscopic resection of the Bennett lesion via posterior and anterior portals.
• Involves debridement, posterior capsular release, and burr resection.
• Potential concurrent repair of posterior labral tears if present.

Main Results:

• Successful treatment of Bennett lesions with good outcomes.
• Return to preinjury levels reported in 69% to 85% of patients following arthroscopic resection.
• High patient satisfaction (88%) reported when using specific diagnostic criteria.

Conclusions:

• Accurate diagnosis using specific criteria (X-ray, pain patterns, physical exam, lidocaine response) is crucial.
• Arthroscopic resection is an effective treatment for symptomatic Bennett lesions.
• The described technique provides significant and lasting improvement for throwing athletes.
