摘要

Background

Humeral lateral condyle fractures are common pediatric elbow injuries, with Jakob type III representing the most severe form. While open reduction and internal fixation is the standard treatment, consensus is lacking on the optimal fixation method. Inadequate fixation can lead to serious complications. The efficacy of absorbable internal fixation materials remains debated. This study aimed to evaluate the outcomes of different internal fixation materials for treating these fractures in children.

Methods

A retrospective review was conducted on 51 children (39 male, 12 female; mean age 4.8 years) with Jakob type III fractures treated surgically between January 2020 and December 2023. Patients were divided into three groups based on fixation: Kirschner wires (Group A), metal hollow screws (Group B), and absorbable hollow screws (Group C). Statistical significance was set at P < 0.05.

Results

The average hospitalization was 3.8 ± 0.2 days, median operation time was 60 min, and mean follow-up was 25.2 ± 12.1 months. No significant differences were found among groups regarding gender, age, postoperative plaster fixation time, final carrying angle, elbow varus deformity, lateral condyle protrusion, Mayo elbow score, or satisfaction. However, significant differences existed in hospital stay, operation time, time to implant removal, total hospitalization costs, and material costs. Group B had a significantly longer hospital stay (mean 4.9 days) compared to Groups A and C (3.5 and 3.4 days). Operative time was longest in Group A (mean 60 min vs. 45 and 47 min). Implant removal time was significantly longer in Group B (median 93 days vs. 34 days in Group A). Group B had the highest total hospitalization costs (mean $2623.0), while Group C had the highest material costs (mean $996.5). Group A had the lowest costs in both categories.

Conclusion

Different internal fixation materials achieved comparable therapeutic effects for pediatric Jakob type III lateral condylar fractures. Absorbable screws provided the advantage of eliminating the need for a second surgery for removal.
