OBJECTIVE
To develop a surgical technique for percutaneous upper extremity fracture fixation using a novel glass-based adhesive.
METHODS
Three intact upper extremity cadaveric specimens with undisturbed soft tissues were obtained. Two were used to model a wrist fracture, and the third to model a proximal humerus fracture. Fractures were produced using a small osteotome in a percutaneous fashion. Banna Bone Adhesive (BBA) was delivered to the fracture site percutaneously using a 16 gauge needle under bi-planar fluoroscopic guidance. After setting of the adhesive, the specimens were dissected to qualitatively assess BBA delivery and placement.
RESULTS
The adhesive could readily be delivered through the 16 gauge needle with an appropriate amount of pressure applied to the syringe. Using the fluoroscope, the adhesive could be seen to flow into the fracture site with minimal extravagation into the surrounding soft tissues. Successful bonding of the fracture fragments was observed.
CONCLUSIONS
Percutaneous delivery of BBA into a fracture of the distal radius and proximal humerus may be a feasible fracture fixation technique. Biomechanical testing and animal model testing are required to further develop this procedure.
目的
开发一种使用新型玻璃基粘合剂进行经皮上肢骨折固定的手术技术。
方法
获取三个软组织未受干扰的完整上肢尸体标本。其中两个用于模拟腕部骨折，第三个用于模拟肱骨近端骨折。使用小型骨凿以经皮方式造成骨折。在双平面荧光透视引导下，通过16号针头经皮将版纳骨粘合剂（BBA）输送至骨折部位。粘合剂凝固后，对标本进行解剖以定性评估BBA的输送和放置情况。
结果
在对注射器施加适当压力的情况下，粘合剂能够轻松通过16号针头输送。使用荧光透视仪可以看到，粘合剂流入骨折部位，极少渗入周围软组织。观察到骨折碎片成功粘合。
结论
将BBA经皮输送至桡骨远端和肱骨近端骨折部位可能是一种可行的骨折固定技术。需要进行生物力学测试和动物模型测试以进一步完善该手术方法。
