OBJECTIVE  The aim of this study was to report efficacy of a modified tibial plateau levelling osteotomy (TPLO) with double cut and medial crescentic closing wedge osteotomy (TPLO/MCCWO) to treat dogs with cranial cruciate ligament rupture and concurrent tibial valgus. STUDY DESIGN  This study was a cases series. MATERIALS AND METHODS  Medical records of dogs that had TPLO with medial crescentic closing wedge osteotomy were reviewed. Data collected included signalment, body weight, pre- and postoperative tibial valgus angle, tibial plateau angle (TPA), surgical planning, corrective osteotomy technique, method of fixation, complications, and length of time to radiographic healing. RESULTS  Fifty-two surgical procedures performed in 45 dogs (7 bilateral) were included in the study. Mean age at surgery was 54 months, and body weight ranged from 5 to 63 kg (mean: 36.5 kg). Mean pre- and postoperative mechanical medial proximal tibial angle were 101° (98°-107°) and 92.80° (88°-97°) respectively. The mean pre- and postoperative TPA were 27.80° (16-35°) and 6.50° (3-11°) respectively. Intraoperative complications occurred in two stifles: in one stifle over-rotation of the proximal tibial segment resulted in a TPA of -8°, with immediate revision to a 5° TPA; in the second stifle a fissure of the lateral tibial cortex developed during insertion of a screw and required adjunctive fixation. No postoperative complications were recorded and all osteotomies healed uneventfully. CONCLUSIONS  Tibial plateau levelling osteotomy/medial crescentic closing wedge osteotomy is an effective treatment for dogs with cranial cruciate ligament rupture and tibial valgus allowing accurate correction of the tibial deformity with a low complication rate.

具有双切口和内侧新月形闭合楔形截骨术的改良胫骨平台水平截骨术，用于治疗具有颅交叉韧带破裂和胫骨外翻畸形的狗。

目的本研究的目的是报道一种改良的胫骨平台平整截骨术（TPLO），双切和内侧新月形闭合楔形截骨术（TPLO / MCCWO）治疗具有颅骨十字韧带断裂和并发胫骨外翻的狗的疗效。研究设计本研究是一个病例系列。材料与方法回顾了患有TPLO并伴有新月形闭合楔形截骨术的狗的病历。收集的数据包括信号，体重，术前和术后胫骨外翻角，胫骨平台角（TPA），手术计划，矫正截骨术技术，固定方法，并发症以及放射线愈合的时间长度。结果本研究包括对45只狗（7只双侧）进行的52次手术。手术的平均年龄为54个月，体重从5公斤到63公斤不等（平均36.5公斤）。术前和术后机械性胫骨近端内侧平均角度分别为101°（98°-107°）和92.80°（88°-97°）。术前和术后平均TPA分别为27.80°（16-35°）和6.50°（3-11°）。术中发生的并发症有两处窒息：一处胫骨近端节段过度旋转导致TPA为-8°，立即修订为5°TPA。在第二个窒息中，在螺钉插入过程中形成了胫骨外侧皮质的裂痕，需要进行辅助固定。没有术后并发症的记录，所有切骨术均愈合良好。
