## Abstract

Surgical intervention is indicated for significantly displaced lateral humeral condyle fractures (LHCFs) in children. Arthroscopic-assisted closed reduction represents a minimally invasive alternative; however, its widespread adoption has been limited by the technical challenges inherent in both pediatric fracture management and elbow arthroscopy. This study introduces a simplified technique utilizing a single proximal anterolateral portal for arthroscopic-assisted reduction, which has shown promising efficacy and safety.

A retrospective analysis was performed on 18 pediatric patients with LHCFs who underwent arthroscopic-assisted closed reduction via a single proximal anterolateral portal at our institution between March 2024 and February 2025. The cohort included 14 boys and 4 girls, with a mean age of 6.1 ± 1.6 years. The mean interval from injury to surgery was 4.7 ± 2.1 days. Data on fracture classification, operative time, duration of K-wire fixation, and functional outcomes were collected and analyzed.

All 18 patients successfully underwent the procedure. The mean operative time was 56.9 ± 10.0 min, and K-wires were maintained for a mean of 35 ± 8.5 days. At the final follow-up, no significant differences in the carrying angle were observed between the injured and contralateral limbs. According to the Flynn criteria, 16 cases were rated as excellent and 2 as good. One case of a superficial pin site infection resolved with conservative wound care. No instances of delayed union, nonunion, neurovascular injury, or compartment syndrome were recorded.

The single proximal anterolateral portal technique for arthroscopic-assisted reduction of LHCFs facilitates minimally invasive debridement of the fracture site and provides direct visualization of the reduction process. This approach serves as a viable and effective alternative for managing lateral condylar fractures that are not amenable to conventional closed reduction due to severe displacement or a prolonged delay from injury. The technique demonstrates a favorable safety profile, and shows promise for broader clinical adoption pending further validation.
