Imaging of the overhead throwing athlete

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Diagnostic Imaging

Background:

• Overhead throwing athletes experience unique injuries, particularly at the shoulder and elbow.
• Rotator cuff tears and labral injuries are common due to tensile overload, impingement, and overuse.
• Elbow injuries often result from valgus forces, affecting the ulnar collateral ligament, ulnar nerve, and common flexor tendon.

Purpose of the Study:

• To emphasize the importance of biomechanical knowledge in diagnosing throwing-related injuries.
• To correlate specific throwing motions with common pathologies in the shoulder and elbow.
• To provide a foundation for understanding treatment strategies based on injury mechanisms.

Main Methods:

• Review of biomechanical principles in overhead throwing.
• Correlation of biomechanical stress with common injury patterns in throwing athletes.
• Analysis of diagnostic imaging findings related to shoulder and elbow pathologies.

Main Results:

• Shoulder injuries include rotator cuff tears and labral degeneration/tears from tensile overload and impingement.
• Elbow injuries involve the ulnar collateral ligament, ulnar nerve, and common flexor tendon due to valgus forces.
• Capitellar osteochondral injuries and loose bodies are also frequently observed in throwing athletes.

Conclusions:

• Understanding the biomechanics of overhead throwing is essential for accurate diagnosis of athletic injuries.
• Knowledge of injury pathophysiology guides effective treatment rationales for shoulder and elbow conditions in throwing athletes.
• Diagnostic imaging interpretation is enhanced by understanding the specific stresses encountered in throwing motions.
