ABSTRACT

We investigated the effect of age and surgery procedure on clinical and radiological outcomes in children with developmental dysplasia of the hip (DDH) who were treated before or after 18 months of age.

Between January 1997 and December 2010, 46 hips of 35 patients were included in this retrospective study. The patients who treated for DDH, followed regularly for at least 4 years and at the last 5 years and above in time of the last controlled. Group 1 (≤18 months) comprised patients who underwent open reduction through the anterior approach, and Group 2 (>18 months) comprised patients who underwent anterior open reduction plus Salter innominate osteotomy

With respect to clinical and radiological outcomes, although Group 1 was more successful than Group 2, there was no significant difference between the groups (p=0.332 and p=0.425, respectively). In contrast, the necessity of a revision surgery and avascular necrosis of Group 2 from Group 1 was higher, and there was a significant difference between the groups (p=0.30 and p=0.046, respectively).

Successful in terms of clinical and radiological results to be higher than the rate in group 1 is remarkable. Moreover, avascular necrosis development and implementation of secondary surgery were less observed in young children who were treated with only open surgery, thereby suggesting that better results are achieved with simple procedures and at an early age in DDH treatment.
