Arthroscopy of the shoulder joint

Area of Science:

• Orthopedic Surgery
• Diagnostic Imaging
• Minimally Invasive Procedures

Background:

• Arthroscopy provides superior visualization of shoulder joint internal structures compared to open procedures.
• Diagnostic imaging modalities like computed tomography (CT) scans, ultrasound, and arthrography have limitations in shoulder lesion detection.

Observation:

• Diagnostic arthroscopy demonstrated higher reliability than CT scans, ultrasound, and arthrography in evaluating 174 shoulder lesions.
• Ultrasound results were disappointing, potentially due to equipment and expertise issues, not inherent method flaws.
• Arthrography showed a high incidence of false results.
• Arthroscopy allows assessment of the long biceps tendon, glenohumeral ligaments, and rotator cuff lesions, aiding in diagnosing instability and planning surgery.

Findings:

• Arthroscopy is a highly reliable diagnostic tool for shoulder lesions, surpassing conventional imaging.
• While treatment can be performed during the same session, operative arthroscopy is best reserved for simpler procedures due to technical demands and high complication rates.
• Simpler procedures like irrigation, labral trimming, biceps tenotomy, and loose body removal yield excellent results.
• Arthroscopic repair of the rotator cuff and labral stapling show questionable success rates and higher complication risks.

Implications:

• Diagnostic arthroscopy precisely identifies shoulder pathology, enabling targeted open procedures and minimizing operative trauma.
• Further improvements in arthroscopic surgical equipment and techniques are needed for more complex interventions.
• The diagnostic accuracy of arthroscopy guides surgical planning, optimizing patient outcomes for shoulder instability and lesions.
