[Acetabular roof remodeling after varus derotation osteotomy in congenital hip dysplasia].
The aim of this paper was to evaluate the acetabular roof remodelling process and changes of the Wiberg angle after proximal femur varus drotational osteotomy up to skeletal maturity. The analysis included 33 patients after 48 osteotomies (in 15 patients on both sides). The age at the time of surgery ranged from 1.0 to 9.8 years, mean 4.7 years. Follow-up time ranged from 7.6 to 15.9 years, mean 12.0 years. Statistical analysis showed significant differences in acetabular index, Sharp's angle, acetabular ratio and Wiberg's angle between early post-operative x-rays and radiograms taken at the last follow-up. Comparison not only of the remodelling dynamics, but also final radiological measurements confirm the necessity for surgical of severely dysplastic acetabular roof, especially in older age groups.
