UCL Injury Mechanism Insight

  • The medial ulnar collateral ligament (UCL) injury leads to valgus instability mostly in overhead throwing athletes.
  • Overuse and repetitive valgus stress cause microtrauma, typically affecting the anterior band of the UCL.
ADVICE

Rest and Strengthening as First Steps

  • Initial treatment for adolescent UCL injuries includes activity avoidance and rest for six weeks.
  • Begin flexor pronator strengthening as inflammation resolves before starting a controlled throwing program.
INSIGHT

Primary Valgus Stabilizer

  • The anterior band of the anterior bundle of the UCL is the primary static stabilizer against valgus stress.
  • The flexor pronator mass provides dynamic stabilization, but does not contribute to static valgus stability.
