Twenty femoral lengthenings were performed with a staged lengthening technique with the Barnes device. After the plate is attached to the femur, the femur is lengthened 2 cm initially and at two or more subsequent stages. Average length gained was 5.4 cm (range 2.5-8.3 cm), and there were no malunions or nonunions. There were two transient peroneal palsies, but no permanent nerve injuries. There were no pin tract problems, no chronic infections, and no knee subluxations. The complication rate with this technique compares favorably with those of other methods.
采用Barnes装置的分期延长技术对20例患者进行了股骨延长术。将钢板固定于股骨后，最初先将股骨延长2 cm，随后在两个或更多阶段继续延长。平均延长长度为5.4 cm（范围为2.5 - 8.3 cm），未出现骨不连或骨畸形愈合情况。出现了2例短暂性腓总神经麻痹，但无永久性神经损伤。未出现针道问题、慢性感染及膝关节半脱位。该技术的并发症发生率优于其他方法。
