Outcomes of Arthroscopy-assisted Closed Reduction and Percutaneous Pinning for a Displaced Pediatric Lateral Condylar Humeral Fracture.

Background: Since 2015, we have performed arthroscopy-assisted closed reduction and percutaneous pinning (A/S-CRPP) for children with a displaced lateral condylar humeral fracture (LCF). The purpose of this study is to introduce our A/S-CRPP method and present its outcomes.

Methods: In total, 39 displaced (>2 mm) LCFs for which A/S-CRPP was initially attempted and with available follow-up data of >12 months were retrospectively reviewed.
