Abstract

Objectives: This study aims to compare low-grade lytic spondylolisthesis (LS) and degenerative spondylolisthesis (DS) radiologically. In addition, it seeks to identify underlying similarities between LS and DS.

Methods: This study included patients with low-grade single-level spondylolisthesis at L4-L5 or L5-S1. They were categorized into LS and DS. Radiological features, including pedicle height, width, transverse, and sagittal angle, as well as anterior vertebral heights (AVH) and posterior vertebral heights (PVH), were measured using T1-weighted magnetic resonance imaging.

Results: The study involved 88 patients: 46 in the DS group and 42 in the LS group. In the LS group, the AVH was significantly higher than the posterior height at L4 and L5 (L4 PVH/AVH ratio 0.93 in LS vs. 0.96 in DS; L5 PVH/AVH ratio 0.84 in LS vs. 0.92 in DS), and pedicles were more medially oriented (L4: 19.62° in LS vs. 17.7° in DS; L5: 28.92° in LS vs. 26.47° in DS). In addition, at L5, the pedicle height (10.67 mm in LS vs. 11.48 mm in DS) and width (13.56 mm in LS vs. 14.37 mm in DS) were smaller compared to the DS group.

Conclusions: Low-grade LS shows distinct radiological vertebral and pedicle anatomy compared to DS. Short and thin pedicles and wedge-shaped vertebrae in LS resemble DS, indicating its dysplastic origin.

低度溶解性脊柱滑脱与退行性脊柱滑脱的放射学参数比较--确定其发育不良起源的回顾性方法。
研究目的:本研究旨在从放射学角度比较低度溶解性脊柱滑脱症(LS)和退行性脊柱滑脱症(DS)。此外,研究还试图找出 LS 和 DS 之间潜在的相似之处:研究对象包括 L4-L5 或 L5-S1 低位单水平脊柱滑脱症患者。他们被分为 LS 和 DS 两类。使用 T1 加权磁共振成像测量放射学特征,包括椎弓根高度、宽度、横向和矢状角,以及椎体前部高度(AVH)和椎体后部高度(PVH):研究涉及 88 名患者:DS 组 46 人,LS 组 42 人。在LS组中,L4和L5的AVH明显高于后方高度(L4的PVH/AVH比值在LS中为0.93,在DS中为0.96;L5的PVH/AVH比值在LS中为0.84,在DS中为0.92),而且椎弓根更偏向内侧(L4:在LS中为19.62°,在DS中为17.7°;L5:在LS中为28.92°,在DS中为26.47°)。此外,L5的椎弓根高度(LS为10.67毫米,DS为11.48毫米)和宽度(LS为13.56毫米,DS为14.37毫米)均小于DS组:结论:与DS相比,低级别LS显示出明显的放射学椎体和椎弓根解剖结构。结论:与DS相比,低级别LS表现出独特的椎体和椎弓根解剖学特征,LS中短而薄的椎弓根和楔形椎体与DS相似,表明其来源于发育不良。
