Purpose: The purpose of this study was to assess if the use of the “endobutton” technique via an arthroscopically-assisted approach was associated with good patient reported outcome measures and low complication rates in select adolescent patients with displaced lateral third clavicle fractures. Methods: A retrospective review of displaced lateral third clavicle fractures sustained in adolescents treated operatively using the endobutton technique over a 2 year period was carried out at our institution. Four cases were identified, all sustained while involved in sporting activities and all were treated via an arthroscopically-assisted approach. Results: all 4 patients scored 0 on the Quick DASH assessment score. No hardware required removal and all patients returned to sport at the same level. Conclusions: Displaced lateral clavicle fractures in adolescents can pose a significant challenge in terms of management options. Use of the endobutton technique via an arthroscopic-assisted approach can offer a safe and effective means of treatment with excellent patient reported outcomes and low complications rates.
