# Surgical Management of Pediatric Acetabular Fractures: A Retrospective Study of 14 Rare Cases

## TL;DR

This study examines surgical outcomes for 14 rare pediatric acetabular fractures and finds that even delayed surgeries can lead to good recovery when performed by experienced teams.

## Contribution

The study provides clinical evidence that delayed surgical treatment of pediatric acetabular fractures can still result in favorable outcomes.

## Key findings

- All 14 pediatric patients achieved bone union after surgical treatment.
- 71.42% of patients had excellent Harris Hip Scores, indicating strong functional recovery.
- Mild hip pain occurred in three patients, but no major complications were reported.

## Abstract

Acetabular fractures in children are extremely rare, accounting for approximately 1%–4.6% of all pediatric fractures. Due to their rarity, literature on these injuries is limited, with only a few reported cases. The primary objective of this study was to present a series of uncommon pediatric injuries, outline our management approach, and demonstrate that even patients undergoing delayed surgical intervention can achieve favorable clinical outcomes.

This retrospective study reviewed records of skeletally immature patients with traumatic acetabular fractures treated at our institution. Patients were surgically treated with open reduction and internal fixation through lateral rectus abdominis approach; follow‐ups included radiological assessment of bone union and internal fixation integrity. Postoperative reduction was evaluated using Matta's criteria, while functional outcomes were measured via the Modified Merle d'Aubigné and Postel Method (pain, gait, mobility) and the Harris Hip Score (HHS). Complications were documented throughout follow‐up.

Between January 2019 and January 2025, 14 pediatric patients with acetabular fractures (five males, nine females; mean age 11.42 ± 2.24 years) were treated and followed for an average of 33.71 ± 14.41 months. Injuries resulted from falls (57.14%), car accidents (28.57%), and motorcycle/bicycle accidents (7.14% each). According to Judet and Letournel classification, fractures included double‐column (57.14%), transverse (35.72%), and anterior with posterior hemi‐transverse (7.14%). All underwent surgery, achieving bone union. The mean Harris Hip Score was 90.35 ± 5.58, with 71.42% rated excellent, 21.42% good, and 7.14% fair. The mean Merle d'Aubigné score was 17.21 ± 1.12. Mild hip pain occurred in three patients, with no other complications.

Pediatric acetabular fractures, typically caused by high‐energy trauma, require treatment focused on optimal outcomes and anatomical reduction, even in delayed cases. This study shows that, in specialized centers, experienced surgical teams can achieve successful reduction and satisfactory results despite delayed intervention.

This case series of 14 pediatric acetabular fractures surgically managed via open reduction and internal fixation through a lateral rectus approach demonstrates that favorable functional outcomes are achievable, even in non‐acute cases, when performed by an experienced surgical team. Follow‐up revealed significant hip function recovery.
