We also present our related literature review on various osteotomy techniques.Methods We reviewed the radiological indices of 27 dysplastic hips in 25 children with cerebral palsy and developmental dislocation of the hips (9 boys, 16 girls; mean age, 5 years) who underwent a modified Dega osteotomy according to Paley.Results Comparing the radiological indices results between our patients and those reported by the various authors in the literature, the data are almost identical.Conclusions The modified Dega osteotomy is the only technique wherein all two limbs of the triradiate cartilage are true, which becomes a single hinge where the osteotomy turns. Despite the similar results in the radiological indices between our patients and those in the literature, we still consider that the entire triradiate cartilage is a better hinge point for the iliac osteotomy. The difference between the osteotomy adopted in our institution and the modality described by most authors in the literature is that the latter mostly ignore or miss the ischial limb of the triradiate cartilage.
