Two unusual presentations of focal fibrocartilaginous dysplasiaMooney, James F.; Slone, Harris S.Journal of Pediatric Orthopaedics B: July 2013 - Volume 22 - Issue 4 - p 367–371 doi: 10.1097/BPB.0b013e3283563732 Femur & Knee Abstract Author Information Focal fibrocartilaginous dysplasia (FFCD) is an uncommon, yet well documented, cause of long-bone angular deformities in children. We report two unusual cases of FFCD involving the tibia: one within the proximal tibia inducing genu valgum and one apparent FFCD lesion of the distal tibia that generated a varus deformity of the distal tibia. To our knowledge, this is the first reported case of FFCD in the distal tibia. Each lesion led to an angular deformity that required surgical management.
