[Salter's single-stage bilateral pelvic osteotomy]
Insights
One-stage bilateral innominate osteotomy is a safe and effective surgical option for treating hip dysplasia in children. This approach corrects acetabular deformities, yielding excellent long-term results with minimal complications.
Area of Science:
- Pediatric Orthopedics
- Surgical Innovation
- Hip Dysplasia Treatment
Background:
- Congenital dislocation of the hip and acetabular dysplasia are common pediatric orthopedic conditions.
- Traditional treatments may involve multiple surgical stages.
- Bilateral innominate osteotomy aims to correct acetabular deformities in a single procedure.
Purpose of the Study:
- To evaluate the efficacy and safety of a one-step bilateral innominate osteotomy.
- To compare simultaneous versus successive osteotomy techniques.
- To assess long-term outcomes and complication rates.
Main Methods:
- 45 children with congenital hip dislocation or acetabular dysplasia underwent a single-stage bilateral innominate osteotomy.
- Procedures included simultaneous (15 children) and successive (30 children) osteotomy.
- Follow-up averaged 4 years and 3 months, with acetabular angle measurements.
Main Results:
- Significant correction of acetabular deformity was achieved (average angle reduced from 36.6° pre-op to 11.5° at follow-up).
- Excellent results were observed in 83 hips; fair in 3; poor in 4 (contraindicated cases).
- Complications were rare, including superficial infections and hip instabilities.
Conclusions:
- One-step bilateral innominate osteotomy is a viable and simple surgical option.
- It eliminates the need for a second operation and offers improved angular correction.
- The procedure demonstrates a favorable safety profile and efficacy in pediatric hip dysplasia treatment.
Abstract:
45 children (3 years 9 months old in average), suffering from congenital dislocation of the hip or acetabular dysplasia have sustained a bilateral innominate osteotomy in a single stage. Two different operative procedures have been used: "simultaneous osteotomy" (15 children) and "successive osteotomy" (30 children). The post-operative follow-up lasted 4 years 3 months. On both sides, the correction of acetabular deformity was obtained, the average value of the acetabular angle which was 36.6 in a pre-operative state, being 17.1 post-operative and 11.5 at the last follow-up. Complications were rare (3 superficial infections, 1 Kirschner wires migration and 2 hip instabilities which called for a capsulorraphy). The results were excellent for 83 hips, fair for 3 hips in 3 children (asymmetrical shift of the osteotomy) and poor for 4 hips in 3 children (who were contraindications of the Salter's osteotomy). The authors conclude that one-step bilateral innominate osteotomy is viable and simple. It makes a second operation unnecessary and results in a better angular gain compared to that obtained after unilateral osteotomy.
