摘要
目的探讨颅骨骨瓣的固定技术,评估颅骨钛铆钉固定骨瓣的优越性。方法6个颅骨标本共制备24个骨瓣,丝线、不锈钢丝和颅骨钛铆钉三种方法分别各固定8个骨瓣,就操作时间、初始移位、垂直受力试验及最大承受力等方面进行比较。结果颅骨钛铆钉固定的操作时间最短,初始移位最小,其垂直受力试验结果优于不锈钢丝和丝线,同时颅骨钛铆钉的最大承受力与不锈钢丝相近而明显大于丝线。结论颅骨钛铆钉操作简便快速,具有良好的复位效果及较大的强度,是较理想的颅骨固定装置。
objective To compare different techniques in cranial flap fixation. Methods Twenty four cadaver craniotomy flaps were divided into three groups, in each group flaps were reattached with sutures, stainless steel wires and titanium clamps respectively. Bone flap fixation was timed and measured for offset. With craniotomied skull for every fixation technique, load-bearlng tests were performed by applying an external force until the failure of the fixation system. Results Titanium clamp required significantly less time [（93±15） s] to fix than either suture [（173±17 ）s] or stainless steel wire [（399±61）s]. Titanium clamp also showed significantly smaller offset [maximal：（0.32±0.23 ）mm];average：[（0.21±0.16 ）mm] than either suture [maximal：（3.00± 0.47 ） mm];average：[（2.24±0.29 ） mm] or stainless steel wire [maximal： （2.01 ±0.36 ） mm];average：[（1.36±0.44）mm]. Titanium clamp was stronger than suture and stainless steel wire. Conclusion Titanium clamp is ease to use, require less time consumption with satisfactory accuracy and strength.
