两名患者因电脉冲通过不成熟的骨骼传播而出现骨骼发育和功能的严重问题。第一个病例的截肢残端翻修提供了评估特定组织学和形态学变化的机会。电损伤完全破坏了干骺端和骨骺骨化中心的部分骨小梁。股骨远端的骺板存在形态学不规则性，而胫骨近端则由于骺板的电烧蚀而完全停止生长。最初损伤后一年多时间里，几乎没有骨内膜或骨膜愈伤组织，没有小梁间炎症反应，也没有新骨形成。膝关节出现严重的纤维性强直。在第二种情况下，近端胫骨骺板后外侧部分的局部停滞导致外翻/反弯变形，并且可能充分减慢了残端末端的远端生长，以防止胫骨不规则的末端过度生长，尽管它确实发生在腓骨中。
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.
