A 7-year-old male castrated domestic shorthair cat was presented for treatment of a bilateral sacroiliac luxation (SIL). CT was performed and the data were extracted in a stereolithography (STL) file, after which a 3D-printed drill guide (3DPDG) was devised, using computer-aided design (CAD) software, and printed. Using an open surgical approach, the guide was used as an aid for drilling the sacrum. The ilial wings were drilled free-hand later and a transiliosacral pin (TP) was inserted to realign and stabilise the SIL. The cat exhibited an early return to normal limb function and a CT scan performed at the postoperative follow-up showed early signs of bone remodelling at the sacroiliac joint.
To the authors' knowledge, this is the first report using a 3DPDG for implant placement in the feline sacrum without intraoperative imaging.
一只7岁已去势的雄性家养短毛猫因双侧骶髂关节脱位（SIL）前来接受治疗。进行了CT检查，并将数据提取到立体光刻（STL）文件中，之后使用计算机辅助设计（CAD）软件设计并打印了一个3D打印钻孔导向器（3DPDG）。采用开放式手术方法，该导向器用于辅助在骶骨上钻孔。随后徒手在髂骨翼上钻孔，并插入一枚经髂骶骨钉（TP）以重新对齐并稳定骶髂关节脱位。这只猫肢体功能早期恢复正常，术后随访时进行的CT扫描显示骶髂关节处有早期骨重塑迹象。
据作者所知，这是第一份在没有术中成像的情况下使用3DPDG在猫骶骨中植入植入物的报告。
