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.
Case report.
A 4-year-old, 25.5 kg, female spayed, Siberian Husky.
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.
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.
Based on over a 2-year follow-up, transcutaneous tibial implants allowed for restoration of locomotion.
Transcutaneous tibial implants offer a potentially viable treatment option for restoring ambulation after amputation of the distal aspect of the tibiae in the dog.
报告用于一只犬双侧骨盆肢截肢后恢复行走能力的定制经皮胫骨植入物的手术规划、技术及长期结果。
病例报告。
一只4岁、25.5千克、已绝育的雌性西伯利亚哈士奇犬。
在双侧胫骨远端截肢后，利用骨盆肢的计算机断层扫描构建剩余胫骨的立体光刻模型。立体光刻模型有助于制造可替代缺失胫骨远端节段的植入物。将定制植入物手术植入双肢。
术后立即恢复辅助行走，7天时出现自主运动。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。在初次手术后26个月以及右侧植入物翻修后17个月，犬在行走、小跑和奔跑时的功能得以恢复。
基于超过2年的随访，经皮胫骨植入物可实现运动能力的恢复。
经皮胫骨植入物为犬胫骨远端截肢后恢复行走提供了一种潜在可行的治疗选择。
