Pectoralis major tears: correlation of magnetic resonance imaging and treatment strategies.

Background: Controversy exists in the diagnosis and treatment of pectoralis major tear patterns.

Hypothesis: Magnetic resonance imaging is useful in determining the grade and the location of pectoralis major tears and in guiding toward an appropriate treatment plan.

Study Design: Case series; Level of evidence, 4.

Avulsion fracture of the ulnar sublime tubercle in overhead throwing athletes.

Background: Injuries to the ulnar collateral ligament are relatively common in throwing athletes and result from either acute traumatic or repeated valgus stress to the elbow. Avulsion fracture of the sublime tubercle of the ulna is a rarely reported site of ulnar collateral ligament injury.

Purpose: We retrospectively reviewed our cases of ulnar collateral ligament injuries to study avulsion fractures of the sublime tubercle of the ulna.
