Asymmetrical arrest of the proximal tibial physis and genu recurvatum deformity.

We are reporting six cases of premature asymmetrical closure of the proximal tibial physis and associated genu recurvatum deformity and have reviewed the fourteen cases reported in the English-language literature. No single etiological factor could be implicated as the cause of the physeal arrest. Trauma, prolonged immobilization, tibial wire traction, and a surgical procedure involving the proximal tibial physis were observed risk factors among our patients. In our patients, established genu recurvatum due to deformity of the proximal end of the tibia and associated tibial length discrepancy were managed successfully by an opening-wedge osteotomy through the proximal one-third of the tibia and bone-grafting. Epiphyseodesis in the contralateral extremity may be required in patients with significant shortening of the tibia.
