Premature physeal closure after tibial diaphyseal fractures in adolescents.
Seven cases of premature physeal closure secondary to diaphyseal fractures of the tibia in adolescents between 12 and 15 years of age are presented. At the time of the accidents, there was no evidence of physeal lesion in any of the patients. After 4 to 13 months of follow-up (mean, 9 months), early closure was observed in the radiologic controls of one or more physes of the affected leg: distal femoral and proximal and distal tibial in three cases, isolated distal femoral physis in three cases, and both tibial physes without femoral damage in one case. Physeal closure was always central, and there was no case of angular deformity. After 15 to 42 months of follow-up (mean, 27 months), all patients had a leg-length discrepancy in the 8- to 30-mm range (mean, 18 mm). Only one patient required surgical correction (proximal epiphysiodesis of the contralateral tibia followed by tibial lengthening). Adolescents with diaphyseal fractures of the long bones should be monitored until they have stopped growing because of the risk of developing leg-length discrepancy as a consequence of premature closure of one or more leg physis.
