一例犬前十字韧带断裂的CTWO治疗

A Case of Cranial Tibial Wedge Osteotomy Treatment of Canine Anterior Cruciate Ligament Rupture

摘要:

1只5月贵宾犬因不慎高处坠落,致左后肢悬空跛行。试验根据触诊、生化血常规、胫骨压缩试验、抽屉试验和X射线的检查结果,对患犬进行手术与复健治疗。结果表明:触诊患肢膝关节,患犬疼痛抗拒,胫骨相对于股骨向前移位;血液生化及血常规检查未出现病理性指标;胫骨压缩试验和膝关节抽屉实验呈阳性;X射线检查可见患肢胫骨平台明显前倾,前术胫骨平台角(TPA)为25°,诊断为前十字韧带断裂。因该犬年龄小,处于骨生长发育阶段,而胫骨平台调平截骨术(TPLO)易影响骺板发育,因此,采用胫骨楔形截骨术(CTWO)进行治疗。术后第5天,病犬患肢可正常运动;术后第10天拆线,患肢完全恢复正常功能。术后2个月拆除骨板,测其TPA 值为4°,且无并发症发生。说明该手术方法疗效理想,同时具备操作简单、稳定性与精确性高的优势,值得在宠物临床推广应用。

Abstract:

A May poodle fell from a high place and the left hind limped.Surgery and rehabilitation were performed based on the results of palpation,blood biochemical and routine tests,tibial compression test,drawer test and Xray examination.The results showed that by palpating the affected knee joint,the dog had pain and resistance,the tibia was shifted forward relative to the femur;blood biochemical and blood routine examination showed no pathological indicators;tibial compression test and knee drawer test were positive;Xray examination showed the affected tibial plateau significantly forward,and tibial plateau angle (TPA) was 25°,and diagnostic result was anterior cruciate ligament rupture.Because the dog was young and in the stage of bone growth and development,and tibial plateau leveling osteotomy (TPLO) easily affected the epiphyseal plate development,so tibial wedge osteotomy (CTWO) was used.On the fifth postoperative day,the affected limbs of the sick dogs can exercise normally;on the 10th postoperative day,the affected limb fully regained its normal function,and the surgical suture was removed;after 2 months,the surgical bone plate was removed,TPA value was measured as 4°,and there were no complications.It indicated that the surgical method has ideal curative effect,and has the advantages of simple operation,high stability and accuracy, which is worthy of clinical promotion and application in pets.
