title: Factors affecting fracture position at cast removal after pediatric forearm fracture.
abstract: The outcome of a pediatric forearm fracture is related to the angulation of that fracture at the time of union. We discuss the factors affecting the position of the fracture at union. Three hundred forty-six children with 369 reductions of forearm fractures were reviewed retrospectively. Quality of reduction at the time of operation and loss of reduction during the period of cast immobilization were assessed using axis deviation. Loss of reduction had a greater influence on the final position of the fracture at union than did the position of the fracture at initial reduction. To ensure a satisfactory outcome, all pediatric forearm fractures should be monitored with radiologic review and remanipulation if their axis deviation is > 5 in younger patients or > 3 in patients with fractures close to or after growth-plate closure. Right forearm fractures in boys were identified as a subgroup at greater risk for redisplacement.
