[Arthrodesis of the shoulder joint]

Area of Science:

• Orthopedic Surgery
• Musculoskeletal System Research

Background:

• Chronic shoulder joint pain significantly impacts function, particularly in physically demanding individuals.
• Functional restoration of the shoulder joint is a critical challenge in orthopedic surgery.
• Rotation loss is a common cause of unsatisfactory outcomes following shoulder procedures.

Purpose of the Study:

• To identify the optimal position for shoulder arthrodesis to improve functional outcomes.
• To evaluate current fixation methods for shoulder arthrodesis.
• To provide guidance for achieving successful surgical results in shoulder joint restoration.

Main Methods:

• Review of existing literature on shoulder arthrodesis techniques and outcomes.
• Analysis of factors contributing to functional failure, specifically rotation loss.
• Evaluation of different joint positioning parameters for shoulder fusion.

Main Results:

• Adherence to strict indications enhances the value of shoulder arthrodesis.
• A specific joint position (20-25° abduction, 30° flexion, 45° internal rotation) is identified as most favorable.
• Compression arthrodesis using one or two AO plates is the preferred fixation method.

Conclusions:

• Shoulder arthrodesis is a valuable surgical option for chronic shoulder pain when indications are strictly followed.
• Correct positioning and modern fixation techniques, such as AO plate compression arthrodesis, are crucial for successful functional recovery.
• Addressing rotation loss through optimal surgical technique is essential for patient satisfaction.
