А clinical case of non-union in a cat after open fracture repair by intramedullary ostheosynthesis of the radius was described. The patient was presented with non-weight bearing lameness, fistulas with purulent discharge, swelling and severe pain. During the surgical revision, after bone sequestrum removal, the bone defect was filled with cancellous and cortical bone autografts. Osteosynthesis with a modified external bone fixator, made of Duracryl Plus - a rapidly self-curing metacrylate polymer - and 6 Kirschner wires passing perpendicularly through both radial cortices was performed. The post-operative period was smooth, and after 23 weeks the external fixator was removed. Radiography showed very good bone healing, with excellent clinical result. The use of the ulna as a donor bone was very convenient because it allowed collecting a cortical graft of larger size. The extremely light model of external bone fixator provided adequate strength of fixation elements and proved to be an efficient and not expensive technique for osteosynthesis in cat with non-union fractures of the distal radius and ulna.
描述了一例猫桡骨开放性骨折髓内骨固定修复术后骨不连的临床病例。患猫表现为负重跛行、有脓性分泌物的瘘管、肿胀和剧痛。在手术翻修过程中，去除骨痂后，骨缺损处用松质骨和皮质骨自体移植物填充。采用由Duracryl Plus（一种快速自固化甲基丙烯酸酯聚合物）制成的改良外固定器和6根垂直穿过桡骨两侧皮质的克氏针进行骨固定。术后过程顺利，23周后拆除外固定器。X线片显示骨愈合良好，临床效果极佳。使用尺骨作为供骨非常方便，因为可以获取更大尺寸的皮质骨移植物。这种极其轻便的外固定器模型提供了足够的固定强度，被证明是治疗猫桡骨远端和尺骨骨不连骨折进行骨固定的一种有效且经济的技术。
