Thoracolumbar intervertebral disc disease is the most common cause of caudal paresis in dogs. Whilst the pathogenesis of the extrusion has been widely studied, treatment protocols and prognostic factors relating to outcome remain controversial. Recent studies have examined a multitude of factors relating to time to regain ambulation after decompressive surgery. Most intervertebral disc herniations occur in the thoracolumbar region, causing upper motor neuron signs in the rear limbs, which are thought to have a more favourable prognosis compared to the lower motor neuron signs created by herniation of an intervertebral disc in the caudal lumbar region. Due to the potential disruption of the lumbar intumescence, lower motor neuron signs have been reported as having a less favourable prognosis. The purpose of this study was to evaluate the intervertebral disc space as a prognostic factor relating to ambulatory outcome and time to ambulation after decompressive surgery. Hansen Type I intervertebral disc extrusions were studied in 308 non-ambulatory dogs. Preoperative and postoperative neurological status, corticosteroid use, signalment, intervertebral disc space, postoperative physical rehabilitation, previous hemilaminectomy surgery, disc fenestration, return to ambulation, and time to ambulation were reviewed.
胸腰椎椎间盘疾病是犬类尾部轻瘫最常见的病因。虽然椎间盘突出的发病机制已得到广泛研究，但与治疗结果相关的治疗方案和预后因素仍存在争议。最近的研究探讨了与减压手术后恢复行走时间相关的多种因素。大多数椎间盘突出发生在胸腰椎区域，导致后肢出现上运动神经元体征，与腰椎尾段椎间盘突出所产生的下运动神经元体征相比，人们认为前者的预后更有利。由于腰膨大可能受到破坏，据报道下运动神经元体征的预后较差。本研究的目的是评估椎间盘间隙作为与减压手术后行走结果和行走时间相关的预后因素。对308只不能行走的犬进行了汉森I型椎间盘突出的研究。回顾了术前和术后的神经状态、皮质类固醇的使用、体征、椎间盘间隙、术后物理康复、既往半椎板切除术、椎间盘开窗术、恢复行走情况以及行走时间。
