To improve implant tolerance and muscle function associated with circular external fixation, the authors substituted divergent titanium pins for the tensioned steel wires used to mount the Ilizarov apparatus on a limb. The first ten patients treated with half-pins were compared to the last ten patients managed with tensioned wires. While the conditions were not exactly comparable, the half-pin group showed improvement over the wire group in categories including time in fixation, implant-site sepsis, range of joint motion, pain medication requirements, and ambulatory capacity. Half-pin mountings require special techniques for a successful application.
为提高与环形外固定相关的植入物耐受性和肌肉功能，作者用发散式钛钉替代了用于将伊里扎洛夫器械安装在肢体上的张紧钢丝。将前10例接受半针治疗的患者与最后10例采用张紧钢丝治疗的患者进行了比较。虽然条件并非完全可比，但半针组在固定时间、植入部位感染、关节活动范围、止痛药物需求和步行能力等方面比钢丝组有所改善。半针固定需要特殊技术才能成功应用。
