Summary
Hip dislocation affects nearly 5% of children with trisomy 21. Early surgical intervention during habitual dislocation offers the best outcomes, while later stages yield poor results.
Area of Science:
- Orthopedics
- Genetics
- Pediatrics
Background:
- Children with trisomy 21 (Down syndrome) have a high risk of hip dislocation.
- This condition can progress from habitual dislocation to subluxation and fixed dislocation if untreated.
Purpose of the Study:
- To describe the natural history of hip dislocation in children with trisomy 21.
- To evaluate the effectiveness of different treatment approaches.
Main Methods:
- Review of clinical and radiological features of 45 hip dislocations in 28 patients.
- Analysis of treatment outcomes, including surgical interventions and non-treatment cases.
Main Results:
- Nineteen patients had no treatment; all remained mobile without significant pain.
- Pelvic or femoral osteotomy with capsular plication during habitual dislocation showed the best results.
- Surgical outcomes were poor for subluxation or fixed dislocation.
Conclusions:
- Early detection and intervention are crucial for managing hip dislocation in trisomy 21.
- Optimal treatment involves surgery during the habitual dislocation phase.
- Delayed treatment leads to poor surgical outcomes.
