UCL Injury

Diagnosis & treatment by Kevin O'Donnell, MD — Coral Gables, FL

Overview

The ulnar collateral ligament (UCL) stabilizes the inner elbow and is the classic overhead-throwing injury. Sprains and tears cause inner-elbow pain and loss of throwing performance, most often in baseball players.

Common Symptoms

  • Inner elbow pain when throwing
  • Loss of velocity or control
  • A 'pop' at the time of injury
  • Tingling into the ring and small fingers

Causes & Risk Factors

  • Repetitive overhead throwing
  • High pitch counts and poor mechanics
  • A single high-stress throw

Treatment Options

  • Rest and a progressive throwing program
  • PRP for select partial tears
  • UCL reconstruction ('Tommy John') for complete tears

Recovery & What to Expect

Partial tears may respond to rest and rehabilitation. Reconstruction has a high return-to-play rate, typically over 9–12 months for throwing athletes.
