Internal Joint Stabilization for Recurrent Nontraumatic Elbow Dislocation in a Skeletally Immature Patient.

Case: A 14-year-old adolescent boy with SCN1B mutation experienced frequent seizures and recurrent elbow dislocation, occurring up to 30 times per day. Following failed conservative treatment, the decision was made to surgically repair the lateral collateral ligament complex and stabilize the elbow with the internal joint stabilizer (IJS). At more than 3 years postoperatively, the patient has not had a dislocation event and will retain the device for the foreseeable future to maintain predictable elbow stability.

Conclusion: Although there is scant evidence supporting the use of the IJS in pediatric cases, the current case supports its use in pediatric elbow instability.
