a Type 5 lesion in a 36-year-old woman. The entire femur was affected by fibrous dysplasia. The neck-shaft angle was 97°. Coxa vara, varus deformity in the proximal femoral shaft, and juxtaarticular valgus deformity in the distal femur were all present, along with knee osteoarthritis. b The coxa vara and varus deformity were corrected with single-level valgus osteotomy made at the vertex of the deformity. The neck-shaft angle was restored to normal (120°). A secondary genu valgum was present with a 20° valgus femorotibial angle. c The osteotomy healed 6 months after the operation. d A supracondylar femoral varus osteotomy was performed to correct the secondary genu valgum. The femur alignment was restored to normal. e A radiograph 96 months after the supracondylar femoral varus osteotomy showed no recurrent deformity
