Progressive valgus deformity after curettage of benign lesions of the proximal tibia.

Background: Progressive valgus deformity after proximal tibial metaphyseal fractures in pediatric patients has been well described, although the pathophysiology is not clear. We performed a retrospective study to evaluate the occurrence of progressive tibia valga after curettage of benign bone lesions of the tibia.

Methods: During a 6-year period, we performed curettage and bone grafting of benign bone lesions of the tibia in 20 patients aged 16 years and younger.
