Posterior Proximal Tibial Hemiepiphysiodesis: A Report of Two Cases

CASE: Apex posterior or recurvatum deformity of the proximal tibia is an uncommon skeletal alignment. Guided growth, or hemiepiphysiodesis, is a well-established technique for correcting periarticular deformities of the knee in children. A novel technique of posterior proximal tibial hemiepiphysiodesis (PPTHE), performed though a posterior approach, is described in combination with physeal bar resection for correction of post-traumatic proximal tibial recurvatum. Two cases are reviewed including surgical technique with 21-month and 30-month outcomes. CONCLUSION: Proximal tibial recurvatum in children can be corrected with posterior proximal tibial hemiepiphysiodesis. The procedure may be combined with physeal bar resection in cases of post-traumatic deformity.
