Experience with an intramedullary skeletal extension and a supracortical extension has been reviewed. Criteria for possible use in future developments have been outlined. Tissue interfacing with the material used in fabricating these devices were briefly discussed, stressing the importance of maintaining the skin's integrity. An artificial tendon, which attempts to bring the external mechanical ankle joint under the direct control of existing skeletal muscles, was described. Three animal models were reviewed and our reasons given for selecting the goat. Preoperative preparations, anesthesia, and the surgical procedures were described in some detail. A tabulation of the procedures done on 52 goats (Table 1) shows little difference between the intramedullary rod and the supracortical devices when only the times in place are compared. However, the supracortical devices showed no bone necrosis and produced only one case of osteomyelitis. With the intramedullary rod, five cases of necrosis and/or osteomyelitis were seen. The cone-shaped supracortical devices are somewhat vulnerable to forces in extension.
回顾了髓内骨骼延长和皮质上延长的经验。概述了未来发展中可能使用的标准。简要讨论了与制造这些装置所用材料接触的组织，强调了保持皮肤完整性的重要性。描述了一种试图使外部机械踝关节在现有骨骼肌直接控制下的人工肌腱。回顾了三种动物模型，并给出了选择山羊的理由。详细描述了术前准备、麻醉和手术过程。对52只山羊进行的手术列表（表1）显示，仅比较植入时间时，髓内棒和皮质上装置之间差异不大。然而，皮质上装置未出现骨坏死，仅发生1例骨髓炎。使用髓内棒时，出现了5例坏死和/或骨髓炎。锥形皮质上装置在伸展时 somewhat vulnerable to forces（此处原文有误，推测可能是“are somewhat vulnerable to forces”，意为“在某种程度上易受外力影响”） 。
