Postoperative Shoulder Imaging: Rotator Cuff, Labrum, and Biceps Tendon.

Area of Science:

• Radiology
• Orthopedic Surgery
• Medical Imaging

Background:

• Postoperative shoulder imaging interpretation is challenging for radiologists and orthopedic surgeons.
• The increasing volume of shoulder rotator cuff, labrum, and biceps tendon repairs necessitates expertise in this area.
• Imaging findings are crucial for predicting prognosis and guiding treatment decisions in shoulder care.

Purpose of the Study:

• To provide guidance on interpreting postoperative shoulder imaging.
• To highlight the importance of understanding surgical techniques and potential complications.
• To emphasize a comprehensive, multimodality imaging approach for accurate diagnosis.

Main Methods:

• Review of common postoperative shoulder surgical procedures.
• Discussion of expected normal findings and potential complications.
• Evaluation of various imaging modalities including MRI, MR arthrography, CT arthrography, and ultrasonography.

Main Results:

• Evolving surgical techniques alter normal shoulder anatomy, complicating preoperative diagnostic standards.
• A multimodality imaging approach, including CT arthrography and ultrasonography, can offer crucial diagnostic information, especially with metal artifacts.
• Radiologists must possess comprehensive knowledge of anatomy, surgical techniques, complications, and imaging pitfalls.

Conclusions:

• Accurate interpretation of postoperative shoulder imaging requires a thorough understanding of surgical procedures and potential complications.
• A multimodality imaging strategy is recommended to overcome limitations of individual techniques and improve diagnostic accuracy.
• Radiologists should integrate knowledge of anatomy, surgical techniques, clinical outcomes, and imaging pitfalls for high-value interpretations.
