Posterolateral rotatory instability, a common elbow issue, stems from lateral ulnar collateral ligament damage. Surgical reconstruction effectively restores elbow function in patients with recurrent instability.

Area of Science:

  • Orthopedic Surgery
  • Elbow Biomechanics
  • Sports Medicine

Background:

  • Posterolateral rotatory instability is the most frequent type of chronic lateral elbow instability.
  • The primary cause involves injury or attenuation of the lateral ulnar collateral ligament (LUCL).
  • Accurate diagnosis relies on detailed patient history and specialized physical examination maneuvers.

Purpose of the Study:

  • To review the diagnosis and management of posterolateral rotatory instability of the elbow.
  • To discuss the efficacy of lateral ulnar collateral ligament reconstruction for chronic lateral elbow instability.

Main Methods:

  • Diagnosis involves thorough patient history and specific clinical tests for elbow instability.
  • Treatment focuses on reconstruction of the lateral ulnar collateral ligament and associated soft tissues.

  • Surgical techniques include both open and arthroscopic approaches.

    • Main Results:

    • Reconstruction procedures generally lead to improved elbow function.
    • Most patients experience satisfactory outcomes following surgical intervention.
    • A common sequela is a mild limitation in the elbow's terminal extension.

    Conclusions:

    • Surgical reconstruction of the LUCL is a recommended treatment for symptomatic chronic lateral elbow instability.
    • Both open and arthroscopic methods offer effective solutions for improving elbow stability and function.
    • Patients should be counseled regarding the potential for mild residual loss of terminal extension.
