目的-报告用于狗双侧骨盆肢体截肢后恢复行走的定制经皮胫骨植入物的手术计划、技术和长期结果。研究-设计案例报告。动物-一只4岁、25.5公斤、已绝育的雌性西伯利亚哈士奇。方法-使用骨盆肢体的计算机断层扫描来建立双侧截肢后剩余胫骨的立体光刻模型胫骨的远端。立体光刻模型促进了植入物的制造，该植入物将取代丢失的胫骨远端节段。通过手术将定制植入物植入双肢。结果-术后立即恢复辅助行走，并在 7 天时出现无辅助运动。 14 个月时，右侧植入物发生无菌性松动，将其取出，并制作并植入了第二个经皮植入物。初次手术后 26 个月和右侧植入物修复后 17 个月，步行、小跑和跑步功能恢复。结论 - 基于 2 年多的随访，经皮胫骨植入物允许恢复运动。临床相关性 - 经皮胫骨植入物为狗胫骨远端截肢后恢复行走能力提供了潜在可行的治疗选择。 (C) 美国兽医学院版权所有 2008。
Objective-To report surgical planning, technique, and long-term outcome of custom transcutaneous tibial implants used to restore ambulation after bilateral pelvic limb amputation in a dog.Study-DesignCase report.Animals-A 4-year-old, 25.5 kg, female spayed, Siberian Husky.Methods-Computed tomographic scans of the pelvic limbs were used to build sterolithographic models of the remaining tibia after bilateral amputation of the distal aspect of the tibiae. The sterolithographic models facilitated fabrication of implants that would replace the missing distal segments of the tibiae. Custom implants were surgically placed in both limbs.Results-Assisted ambulation was restored immediately postoperatively and unassisted locomotion occurred at 7 days. At 14 months, aseptic loosening of the right implant occurred, it was removed and a 2nd transcutaneous implant was fabricated and implanted. At 26 months after initial surgery and 17 months after revision of the right implant, function is restored at a walk, trot, and run.Conclusion-Based on over a 2-year follow-up, transcutaneous tibial implants allowed for restoration of locomotion.Clinical Relevance-Transcutaneous tibial implants offer a potentially viable treatment option for restoring ambulation after amputation of the distal aspect of the tibiae in the dog.
