# Outcomes of internal fixation for pediatric proximal femoral fractures using a 3.5 mm T-plate

## TL;DR

This study shows that using a 3.5 mm T-plate for fixing hip fractures in children leads to good healing and functional outcomes.

## Contribution

The study demonstrates the effectiveness of a 3.5 mm T-plate for pediatric proximal femoral fractures with types II–V.

## Key findings

- All fractures achieved union with a mean time of 8.7 weeks.
- Functional outcomes were good in 64.9% of cases.
- Anatomical reduction was achieved in 24 out of 37 cases.

## Abstract

This study aims to investigate the functional and radiographic outcomes after internal fixation of proximal femoral fractures in children using a 3.5 mm T-plate.

From December 2015 to September 2022, all cases presenting with recent proximal femoral fractures were treated with internal fixation using a 3.5 mm T-plate. All patients were followed up for 24 months. Union time, neck shaft angle, neck length, quality of reduction, and functional outcomes were assessed.

The study included 37 patients; the mean age was 8.6+/- 1.6 (6–11) years. Delbet type IV was the most frequent fracture type (13 cases, 35.1%), followed by type V (10 cases, 27%), and type III (9 cases, 24.3%), with type II accounting for 5 cases. All fractures achieved union with a mean time of 8,7 weeks (range 6–12 weeks), As regards radiographic parameters, the mean neck shaft angle difference was 4.9 (SD 3.7) degrees (range 0–16 degrees) less than the contralateral side, the mean neck resorption ratio was 93.8 +/- 4 (range 85–100), The quality of reduction was anatomical in 24 cases (64.9%), acceptable in 10 cases (37%), and considered unacceptable in 3 cases (8.1%), The functional outcome was good in 24 cases (64.9%), fair in 11 patients (29.7%) and poor in two patients (5.4%).

The use of a contoured 3.5 mm conventional T-plate in the fixation of recent pediatric femoral fractures (types II–V) yields good results regarding union rates, functional outcome, and maintaining the mechanics of the hip.
