Two patients are presented with significant problems of skeletal development and function consequent to electrical impulse propagation through the immature skeleton. Amputation stump revision in the first case allowed an opportunity to assess specific histologic and morphologic changes. Electrical damage completely destroyed portions of trabecular bone in the metaphyses and epiphyseal ossification centers. There were morphologic irregularities in the physis of the distal femur, while in the proximal tibia complete cessation of growth occurred through presumed electrical ablation of the physis. There was virtually no endosteal or periosteal callus, no intertrabecular inflammatory response, and no new bone formation well over a year following the original injury. The knee joint exhibited severe fibrous ankylosis. In the second case localized arrest of the posterolateral portion of the proximal tibial physis caused a valgus/recurvatum deformation, and probably slowed down distal growth sufficiently in the stump end to prevent irregular terminal overgrowth of the tibia, although it did occur in the fibula.
