IntroductionIntroduction
59 cases of established hipdislocation were detected
59 cases of established hip dislocation were detected
All were treated by open reduction with & without salter osteotomy
All were treated by open reduction with & without salter osteotomy
Comparison between hips managed with and without Salter osteotomy was done

METHODS METHODS
We reviewed records of 59 dislocated hips with surgical treatment after 1.5 years of age between 1975- 1992

ConclusionsConclusions
Effects of primary Salter osteotomy compared to no Salter osteotmy:
1- Femoral head is better
2- Acetabulum provided better coverage
3- Avascular necrosis is less
4- higher good results according to Severin classification

In comparing results of primary and secondary Salter osteotomy:
Better end results for primary Salter osteotomy, even though this group was more dysplastic at the start.

SignificanceSignificance
Dislocated hip
Child older than 1.5 years
Routinely including Salter osteotomy with the primary open reduction produces the best result.
