Objective:

Evaluate the results of open reduction associated to a Salter osteotomy at nine months of age for treatment of the developmental Dysplasia of the Hip.

Material and methods:

Case- series of unilateral Developmental Dysplasia of the hip treated between July 2004- December 2008 with follow-up at 3, 6 and 9 months postop.

Results:

16 patients, 13 females (81%) 3 males (19%). we did an open reduction and Salter’s osteotomy at 9 months on average (8- 10 months); the most effected side were the left hip on 75%. at 9 months of follow up 15 patients had a McKay score excellent and 1 good. Only one patient was followed up at one year with no pain, full range of motion and stable.

Conclusion:

open reduction and salter osteotomy without preoperative traction is an effective treatment in the short-term; the range of motion could be affected. It is important that the spica cast were applied in a staged manner and in secured position.
