摘要: 旨在报导3D打印辅助手术治疗1例犬髌骨Ⅳ级内脱伴发前交叉韧带断裂的效果。患有髌骨Ⅳ级内脱伴发前交叉韧带断裂的柴犬采用两种方式治疗,先采用改良式胫骨平台水平化截骨术(tibial plateau leveling osteotomy,TPLO)和楔形滑车成形术治疗,后进行CT扫描和3D打印股骨模型对股骨畸形进行评估,辅助制定手术计划,进行股骨远端外侧闭合楔形截骨术(distal femoral lateral closing wedge osteotomy,DFO)治疗。通过检查患犬跛行程度、髌骨位置和影像学检查来判断患犬的恢复程度。结果显示:改良式胫骨平台水平化截骨术和楔形滑车成形术治疗术后第8周出现髌骨脱位复发,说明该方法无法完全纠正髌骨Ⅳ级内脱。通过3D打印辅助制定手术方案,采用DFO治疗后跛行明显改善,术后恢复良好。综上,在高级别髌骨内脱伴有前交叉韧带断裂的病例中,应该同时注意是否存在股骨畸形;采用3D打印技术可以更准确地评估骨骼形态,辅助制定股骨矫正方案,提高手术成功率。

Abstract: The aim of this study was to report the effect of surgery assisted by 3D printing technique in the treatment of a dog with grade Ⅳ medial patellar luxation and cranial cruciate ligament rupture. A Shiba Inu with grade Ⅳ medial patellar luxation and cranial cruciate ligament rupture is treated in two ways. First, the modified tibial plateau leveling osteotomy (TPLO) and trochlear wedge recession are used. Then, the femoral deformity is evaluated through CT scanning and 3D printing of the femoral model to assist in formulating the surgical plan and carrying out distal femoral lateral closing wedge osteotomy (DFO). The degree of lameness, patella position and imaging examination are used to determine the recovery of the dog. The results showed that patellar luxation recurred 8 weeks after the modified TPLO and trochlear wedge recession, indicating that this method can not completely correct the grade Ⅳ medial patellar luxation. With the help of 3D printing technique, the DFO surgical planning is formulated, lameness is significantly improved after treatment, and postoperative recovery is good. In the case of high-level patellar luxation with cranial cruciate ligament rupture, attention should be paid to whether there is femoral deformity; The use of 3D printing technology can assess bone morphology more accurately, assist in formulating femoral osteotomy plan, and improve the success rate of surgery.

Key words: medial patellar luxation, cranial cruciate ligament disease, modified tibial plateau leveling osteotomy, distal femoral lateral closing wedge osteotomy, 3D printing technology
