Summary

Recurrent elbow dislocations in adolescents can result from medial epicondylar fractures. Surgical repositioning of the fracture fragment stabilized the medial collateral ligament, preventing further dislocations.

Area of Science:

  • Orthopedic Surgery
  • Pediatric Orthopedics
  • Sports Medicine

Background:

  • Recurrent elbow dislocations are uncommon, particularly in pediatric populations.
  • Medial epicondylar fractures can compromise elbow joint stability.
  • Assessing elbow instability requires careful clinical examination and imaging.

Observation:

  • A 13-year-old female presented with recurrent elbow dislocations after a medial epicondylar humerus fracture.
  • Clinical examination revealed significant lateral elbow instability with easy dislocation during pronation of a hyperextended elbow.
  • Radiographs showed non-union of the medial epicondylar fracture fragment.

Findings:

  • Surgical repositioning of the medial epicondylar fracture fragment was performed.

Related Experiment Videos

  • The repositioned fragment effectively tightened the medial collateral ligament.
  • Postoperative follow-up at ten months showed no recurrence of elbow dislocation.

    • Implications:

    • This case highlights the importance of addressing medial epicondylar fractures in pediatric elbow instability.
    • Surgical intervention for non-union of medial epicondylar fractures can restore elbow stability.
    • Proper management of such fractures may prevent chronic instability and recurrent dislocations in young athletes.
