Pediatric proximal tibia metaphyseal fractures, or Cozen fractures, heal reliably but often progress to a valgus deformity. The valgus deformity seen with Cozen fractures is secondary to an increase in metaphyseal growth medially. Zionts and MacEwen peformed a retrospective review of 7 patients with Cozen fractures and found that the valgus angulation progressed most rapidly during the first year after the injury, and then continued at a slower rate for as long as seventeen months. Tuten et al. then re-reviewed this same cohort at 15 year followup and found that the valgus angulation completely resolved in 100% of cases. However, the affected tibia was longer than the contralateral tibia in 100% of cases with an average limb-length discrepancy of 9 mm. Ogden et al., in a retrospective review, found radiographic evidence that the medial metaphysis was longer in every instance compared to the distance laterally. Illustration A is another example of a proximal tibia fracture that developed valgus overgrowth as evidenced in Illustration B. This particular case underwent medial stapling for guided growth. Zionts et al. peformed a retrospective review of 7 patients with Cozen fractures and found that the valgus angulation progressed most rapidly during the first year after the injury, and then continued at a slower rate for as long as seventeen months.
