The efficacy of medical treatments and the changes in radiologic imaging before and after treatment have consistently remained pivotal factors. This is particularly critical for surgical procedures, where precise evaluation of disparities pre and postsurgery or the accuracy of implantation is paramount. Based on three-dimensional morphological interests, we provide an automatic quantification evaluation method that delivers an evident base for assessing the outcomes of a widely employed surgical technique, cervical laminoplasty.
The sample study included patients who underwent cervical laminoplasty for cervical spondylotic myelopathy/ossification of the longitudinal ligament. We present a superimposition method that facilitates a unique and precise assessment between pre and postsurgery. The degree of expansion was evaluated by the canal volume increase and canal expansion rate after surgery.
There were 31 patients with 112 vertebral segments measured. The target cervical's pre and postoperative canal areas were 122.63 ± 30.34 and 196.50 ± 37.10 mm, respectively (P < 0.001). The average cervical canal expansion rate was 64.42%. The expansion effect of C5 cervical laminoplasty was the maximum (71.01%), and the canal volume of other segments expanded by approximately 60%. The functional outcomes demonstrated significant improvements in symptoms.
The quantification evaluation method can be utilized for any morphology changes before and after laminoplasty, as it does not lead to errors or variations from different inspection machines or human factors. The automatic method delivers an evident base for assessing the outcomes of a widely employed surgical technique.
医学治疗的疗效以及治疗前后影像学的变化一直是关键因素。这对于手术程序尤为重要，因为术前和术后的差异或植入物的准确性需要进行精确评估。基于三维形态学的兴趣，我们提供了一种自动量化评估方法，为广泛应用的手术技术——颈椎板成形术的结果评估提供了明显的依据。
本样本研究包括接受颈椎板成形术治疗颈椎病/颈椎后纵韧带骨化的患者。我们提出了一种叠加方法，便于在术前和术后之间进行独特而精确的评估。通过术后椎管容积增加和椎管扩张率来评估扩张程度。
共有 31 名患者的 112 个椎体节段进行了测量。目标颈椎的术前和术后椎管面积分别为 122.63 ± 30.34 和 196.50 ± 37.10mm（P < 0.001）。颈椎管平均扩张率为 64.42%。C5 颈椎板成形术的扩张效果最大（71.01%），其他节段的椎管容积扩大了约 60%。症状的功能结果显著改善。
量化评估方法可用于板成形术前后的任何形态变化，因为它不会因不同的检查机器或人为因素而导致错误或变化。自动方法为广泛应用的手术技术的结果评估提供了明显的依据。
