“…Chin et al observed an approximately two times higher progression rate in patients with LVT C6 mm compared with LVT \6 mm [38]. Consistent results on curve progression were found in all studies when the apical vertebra showed LVT C6 mm compared with \6 mm [8,36,40]. Interestingly, contradicting results were found by Watanuki et al when including patients with LVT C3 mm [43].…”

“…Of the 12 included studies, 6 were of high quality (C9 points [13,[36][37][38][39][40]). Most methodological shortcomings concerned lack of adequate follow-up (item F and G), blinding (item H and J), and statistical analysis (item L and M) ( Table 4; Supplementary Material).…”

“…2). Only one paper (Korovessis et al) did not find this relationship, but their deviation from the common grading scale (i.e., the method by Nash and Moe) and relatively short follow-up time (mean 3.7 years; range 2-5 years) might account for this discrepancy [36].…”

“…Furthermore, it has been hypothesised that vertebral rotation or ''rotational instability'' may be the initial trigger of DNDLS, and therefore, there might be a causal relationship. Vertebral rotation in combination with lateral spondylolisthesis (lateral vertebral translation) [36,43,46] or independently [8,39,41] is moderately associated with curve progression (Fig. 2).…”

De novo degenerative lumbar scoliosis: a systematic review of prognostic factors for curve progression

et al. 2016

Purpose To identify prognostic factors for curve progression in de novo degenerative lumbar scoliosis (DNDLS) by performing a systematic review of the literature. Methods Studies were selected for inclusion following a systematic search in the bibliographic databases PubMed and EMBASE prior to September 2015 and hand searches of the reference lists of retrieved articles. Two authors independently assessed methodological quality. Data were extracted and presented according to a best evidence synthesis. Results The literature search generated a total of 2696 references. After removing duplicates and articles that did not meet inclusion criteria, 12 studies were included. Due to the lack of statistical analyses, pooling of data was not possible. Strong evidence indicates that increasing intervertebral disk degeneration, lateral vertebral translation C6 mm, and an intercrest line through L5 (rather than L4) are associated with DNDLS curve progression. Moderate evidence suggests that apical vertebral rotation Grade II or III is associated with curve progression. For the majority of other prognostic factors, we found limited, conflicting, or inconclusive evidence. Osteoporosis, a coronal Cobb angle \30°, lumbar lordosis, lateral osteophytes difference of C5 mm, and degenerative spondylolisthesis have not been shown to be risk factors. Clinical risk factors for progression were not identified. Conclusions This review shows strong evidence that increased intervertebral disk degeneration, an intercrest line through L5, and apical lateral vertebral translation C6 mm are associated with DNDLS curve progression. Moderate evidence was found for apical vertebral rotation (Grade II/III) as a risk factor for curve progression. These results, however, may not be directly applicable to the individual patient.

“…[17] These studies showed that axial rotation was a factor associated with progression in degenerative lumbar stenosis patients. [18,19] Korovessis et al [20] and Ferrero et al [21] reported the development of disc asymmetry followed by rotational subluxation, including intervertebral skidding and rotation, which causes new degenerative scoliosis as a 3-dimensional deformation mechanism of the spine. In addition, deformation of the vertebral body, facet joint shape, cage angle, cage position after insertion, adjacent facet cavity shape, and osteoporosis may also be involved.…”

Analysis of rotational deformity correction by lateral lumbar interbody fusion with two-staged anterior-posterior combined corrective fusion surgery for adult degenerative kyphoscoliosis

et al. 2022

The present study is retrospective analysis of consecutively collected data. Lateral lumber interbody fusion (LLIF) is widely used in cases of adult spinal deformities. However, the corrective effects of LLIF cage insertion on the vertebral rotation deformity in the axial plane and the individual effects of LLIF and direct vertebral rotation (DVR) on rotational correction are unclear. To individually examine the corrective effects of LLIF and posterior corrective fusion surgery with direct DVR on vertebral rotation deformities in adult degenerative kyphoscoliosis. We analyzed 21 patients (5 males and 16 females) who underwent two-staged anterior-posterior combined corrective fusion surgery for adult degenerative kyphoscoliosis. Surgical time, blood loss, facet joint osteoarthritis (OA) grade, disc degeneration, cage height, vertebral rotational angle, and various X-ray parameters were investigated as evaluation items. The X-ray parameters showed significant postoperative improvements. The mean vertebral rotation angle was 6.4° ± 5.2° preoperatively, 3.5° ± 3.3° after LLIF ( P = .014, vs preoperative), and 1.6° ± 1.7° after posterior corrective fusion surgery with DVR ( P = .011, vs preoperative). Correlation analysis between the vertebral rotation angle and various measured values revealed that the vertebral rotation angle after LLIF was correlated with the cage height ( r = −0.46, P = .032). The vertebral rotation angle after DVR was correlated with the facet joint OA grade ( r = −0.49, P = .018) and the wedge angle after posterior corrective fusion surgery with DVR ( R = 0.57, P = .006). We conclude that the effects of rotational deformity correction with LLIF cage insertion and additional posterior corrective fixation with DVR can be useful for correcting vertebral rotation deformities.
