Minimally invasive, iliac crest-sparing approach for pelvic osteotomies in children.

The aim of this article is to describe a minimally invasive iliac crest-sparing approach (ICSA) allowing common iliac osteotomies in children. The ICSA was used for 98 hips in 72 consecutive patients who underwent a pelvic osteotomy. The mean follow-up duration ranged from 3 to 7 years. Skin incision ranged from 3 to 5.5 cm. Displacement of the distal osteotomy fragment was easy and without tension. The duration of surgery varied from 50 min in the beginning of our experience to 20-25 min for the last cases of the series. In conclusion, the ICSA fulfills all the criteria of minimally invasive surgery.
