Varus-producing osteotomy for patients with lateral pillar type B and C Legg-Calvé-Perthes disease followed to skeletal maturity.
OBJECTIVE
We sought to determine if a varus-producing osteotomy of the proximal femur was related to a better outcome than non-operative treatment for LCP disease.


METHODS
This was a retrospective review of 121 patients; clinical outcome was determined with the Iowa Hip Score, and radiographic outcome was determined with the Stulberg classification.


RESULTS
A total of 73 patients undergoing a VO and 48 treated non-operatively were included; 70 had lateral pillar type B and 51 type C hips. Average follow-up was 12.03 years. The mean Iowa Hip Score was 86.8 for the VO group and 85.9 for the non-operative group. According to the Stulberg classification for the group undergoing a VO, there were 8 type II, 33 type III, and 32 type III, and for the group undergoing non-operative treatment there were 11 type II, 24 type III, and 13 type IV.


CONCLUSIONS
We found no statistically significant difference in the clinical or radiographic result for patients undergoing a VO compared to non-operative treatment.
