颅骨缺损是神经外科领域的一个主要问题,对此类缺损的不当处理可能导致美容问题以及更严重的感染和炎症。临床上有几种策略可以处理这些缺陷,但大多数依赖于容易发生并发症的合成材料;因此,骨再生方法将是优越的上级。我们测试了一种材料(磷酸八钙胶原复合物[OCP/Col]),已知该材料可增强大鼠颅骨缺损模型中的骨再生。使用临界尺寸的大鼠颅骨缺损模型,将OCP/Col植入硬脑膜完整或硬脑膜部分缺损的大鼠中。在12周的过程中,使用计算机断层扫描和组织学分析的结果与未治疗组进行了比较。OCP/Col促进骨再生,无论是否有硬脑膜缺损。OCP/Col可用于治疗颅骨缺损,即使硬脑膜受伤或手术切除,通过骨再生增强OCP/Col的再吸收,从而大大降低感染的风险。
Cranial bone defects are a major issue in the field of neurosurgery, and improper management of such defects can cause cosmetic issues as well as more serious infections and inflammation. Several strategies exist to manage these defects clinically, but most rely on synthetic materials that are prone to complications; thus, a bone regenerative approach would be superior. We tested a material (octacalcium phosphate collagen composite [OCP/Col]) that is known to enhance bone regeneration in a skull defect model in rats. Using a critical-sized rat skull defect model, OCP/Col was implanted in rats with an intact dura or with a partial defect of the dura. The results were compared with those in a no-treatment group over the course of 12 weeks using computed tomographic and histological analysis. OCP/Col enhanced bone regeneration, regardless of whether there was a defect of the dura. OCP/Col can be used to treat skull defects, even when the dura is injured or removed surgically, via bone regeneration with enhanced resorption of OCP/Col, thus limiting the risk of infection greatly.
