Abstract

Cranial cruciate ligament (CCL) disease causes variable stifle instability assessed by specific clinical tests. Radiographs are performed to measure the tibial plateau angle (TPA) for planning tibial plateau leveling osteotomy (TPLO) surgery. Concomitant damage to other intra-articular structures, for which clinical detection is unreliable, may occur and potentially affect the surgical outcome. Joint assessment during TPLO through instrumented inspection is therefore advised, though it increases the risk of complications. Magnetic resonance imaging offers a noninvasive alternative, adds information about intra- and periarticular structures, and could potentially be used for TPA measurements. This prospective study aimed to (1) assess the correlation between the TPA measured with the standard presurgical radiographs and with a single sagittal intermediate-weighted fat-saturated MRI sequence and (2) compare the surgical findings with the information obtained by the MRI sequence. Twenty-one stifles were included; TPA correlation using radiographs-MRI was available for 17 stifles, and surgery-MRI comparison was available for 18 stifles. A strong significant correlation was identified between the TPA measurements on radiographs-MRI (Pearson correlation coefficient 0.923; p-value <.0001). The sensitivity and specificity of MRI to detect surgically confirmed complete versus partial CCL rupture were 85.7% and 75%, respectively; MRI identified 7 of 8 surgically confirmed injured menisci and detected abnormal signal intensity in 8 of 10 medial menisci and nine caudal cruciate ligaments reported as normal intra-operatively. The MRI additionally identified abnormal subchondral bone signals in nine stifles and muscular hyperintensity in six cases. This presurgical MRI sequence might replace standard radiographs for TPA measurements and can provide information about concomitant joint injuries with potential prognostic impact.

单一术前高场MRI序列是否可以取代犬TPLO手术计划的标准x线片?
颅十字韧带(CCL)疾病引起可变的膝关节不稳定性评估的具体临床试验。x线片测量胫骨平台角(TPA),以规划胫骨平台平截骨(TPLO)手术。可能发生其他关节内结构的并发损伤,临床检测不可靠,并可能影响手术结果。因此建议在TPLO期间通过仪器检查进行联合评估,尽管这会增加并发症的风险。磁共振成像提供了一种无创的替代方法,增加了关节内和关节周围结构的信息,并有可能用于TPA测量。本前瞻性研究旨在(1)评估术前标准x线片测量的TPA与单次矢状中权重脂肪饱和MRI序列之间的相关性;(2)将手术结果与MRI序列获得的信息进行比较。其中包括21条窒息;通过x线片- mri的TPA相关性分析17例窒息,手术- mri比较18例窒息。x线片与mri的TPA测量值之间存在很强的显著相关(Pearson相关系数0.923;假定值
