# Hip Dislocation With Femoral Short Neck in Spondyloepiphyseal Dysplasia Treated by Open Reduction and Valgus Osteotomy: A Case Report

## TL;DR

A child with a rare bone disorder had successful hip surgery using a specific technique to stabilize the joint.

## Contribution

The case highlights the effectiveness of femoral valgus osteotomy in treating hip dislocation in SEDC.

## Key findings

- Hip dislocation was corrected using open reduction and valgus osteotomy.
- Stabilization was achieved with hip spica casting after surgery.
- The approach suggests valgus osteotomy is essential for SEDC-related hip issues.

## Abstract

Spondyloepiphyseal dysplasia congenita (SEDC) often involves hip deformity and dislocation. We present a case of an eight-year-old boy with bilateral femoral head deformity and hip dislocation treated by open reduction and femoral valgus osteotomy. Surgery was performed via an anterior approach. After removal of obstructive factors, reduction was only maintained at 30° adduction, necessitating valgus osteotomy to stabilize the hip. Postoperative fixation was achieved with hip spica casting. This case suggests that femoral valgus osteotomy may be essential to maintain reduction in SEDC-associated hip dislocation.
