In patients with pathological fractures an operative stabilisation is indicated without delay although 40 to 50% of the patients survive only three to four months. Generally palliative operations are practiced. Mostly a connecting osteosynthesis is carried out in which after resection of the tumorous bone the stability can be achieved by the application of plates and filling of the bone defect with cement. In three examplary cases a technical improvement of the impaction of bone cement is described. Using an exactly cutted packing ring of a single use syringe after the application of the plate the bone cement can be filled in easily. By the casting a penetration of the bone cement into the soft tissues can be avoided. An additional effect is that pins of cement extend into the bone narrow with a sufficient support of the filling on the cortical bone. After the removal of the casting the screws can be inserted in the overbridged defect while the polymerisation has nearly finished.
对于病理性骨折患者，应立即进行手术稳定治疗，尽管40%至50%的患者仅能存活三到四个月。一般实施姑息性手术。多数情况下进行连接性骨合成，即在切除肿瘤骨后，通过应用钢板和用骨水泥填充骨缺损来实现稳定性。在三个示例性病例中描述了骨水泥打压的技术改进。在应用钢板后，使用一次性注射器精确切割的填充环可轻松填充骨水泥。通过浇铸可避免骨水泥渗入软组织。另一个效果是，骨水泥钉可延伸至骨窄处，对皮质骨上的填充物有足够支撑。在拆除浇铸物后，可在聚合接近完成时将螺钉插入跨越的缺损处。
