The visual analog scale (VAS) scores for neck and arm pain, neck disability index (NDI), and Japanese Orthopedic Association (JOA) scores were analyzed.METHODSThe radiographic and clinical outcomes of the two groups were compared.RESULTSEighty-four patients were included (n=42 in each group) after application of the inclusion criteria and propensity score matching. A significant decrease in C2-C7 lordosis (p<0.001) and ROM (p<0.001) was observed in the LPF and ACDF groups, respectively. LPF was associated with a significant decrease in C2-C7 lordosis (p<0.001), while ACDF caused a significant decrease in cervical ROM (p<0.001). ACDF effectively improved neck pain VAS (p<0.001) and NDI (p<0.001), while neck pain did not significantly improve after LPF (p=0.103). Furthermore, neck pain VAS (p=0.026) and NDI (p=0.021) at postoperative 6 months, were significantly greater in the LPF group than in the ACDF group, while the difference was not statistically significant at 2 years postoperatively (neck pain VAS, p=0.502; NDI, p=0.085). Arm pain VAS and JOA score both significantly improved after LPF (p=0.003 and 0.043, respectively) or ACDF (p<0.001 and 0.039, respectively), and postoperative results were not significantly different between the two groups.CONCLUSIONLPF and ACDF yielded similar outcomes for arm pain and neurological recovery. More immediate neck pain improvement was observed with ACDF, while neck pain after 2 years postoperatively was similar between the LPF and ACDF groups. Furthermore, increased postoperative loss of lordosis was observed in the LPF group, whereas decreased postoperative ROM was observed in the ACDF group. These findings should be considered when deciding the surgical method for patients with CMR.LEVEL OF EVIDENCEIII.","PeriodicalId":22961,"journal":{"name":"The Spine Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142269551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MRI was used to evaluate the change in spinal cord signal intensity. The relationship among gap presence, lesion morphology, and MRI T2 high intensity in the spinal cord was examined.RESULTSA significant difference in gap detection accuracy was observed between CT and 3D-CT (p = 0.0054). CT demonstrated false-positive results in the detection of gaps as compared with 3D-CT. The presence of gaps was significantly associated with an increased likelihood of MRI T2 high intensity in the spinal cord (p = 0.037). Patients with thicker lesions and smaller space available for the spinal cord (SAC) were more likely to exhibit T2 high intensity. Meanwhile, patients with gaps co-occurring with T2 high intensity exhibited significantly thinner lesions (p = 0.011) and larger SACs (p = 0.0002). Patients with gaps had a significantly lower JOA scores (p = 0.0035), which indicates that patient with gaps are likely to exhibit more severe clinical neurological symptoms.CONCLUSION3D-CT showed superiority in accurately identifying gaps within OPLL lesions, while CT demonstrated false-positive results in the detection of gaps. Furthermore, the gap presence was a risk factor for MRI T2 high intensity in the spinal cord, independent of lesion thickness. In addition, gaps are related to more severe clinical symptoms. This study highlighted the importance of evaluating gaps within OPLL lesions using 3D-CT to clarify neurological pathogenesis.","PeriodicalId":22961,"journal":{"name":"The Spine Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, several different types fit in the current definition of HRVA, which may require a different strategy for C2 screw placement.PURPOSETo classify HRVA and provide a clinical aid for preoperative planning of C2 instrumentation. A secondary goal was to estimate coexistence of each HRVA type with the ipsilateral narrow C2 pedicle (NP).STUDY DESIGNA retrospective observational study involving radiologic measurements of the estimated number of anonymized cervical computed tomography (CT) scans. STROBE checklist was applied.PATIENT SAMPLE908 potential screw insertion sites (PSIS) of 454 consecutive cervical CT scans were analyzed. The sample size was estimated using ScalaR SP function in RStudio.OUTCOME MEASURESThree types of HRVA based on a series of C2 vertebral morphological parameters including the C2 isthmus height (C2IsH) and C2 internal height (C2InH). Also, the prevalences of each HRVA type and coexisting NP based on the C2 pedicle width (C2PW).METHODSHRVA was defined as C2IsH of ≤ 5 mm and/or C2InH of ≤ 2 mm measured 3 mm lateral to the lateral border of the spinal canal. A narrow pedicle was defined as C2PW of ≤ 4 mm. Measurements were done using Syn.govia software. Interobserver, intraobserver, and inter-software agreement coefficients for C2IsH, C2InH, and C2PW parameters were adopted from our previous study. K-means cluster analysis was applied.RESULTSPrevalence of at least one HRVA was 24.9% (n = 113 subjects) and 16.2% of PSIS (n = 147 sites). Based on the measurements and K-means clustering, the following three types of HRVA have been distinguished: type 1 - isthmic with only C2IsH being reduced and normal C2InH; type 2 - internal with only C2InH being reduced and C2IsH within normal limits; type 3 - isthmo-internal with both C2IsH and C2InH being reduced. Kruskal-Wallis test followed by unadjusted and Bonferroni-adjusted post-hoc multiple comparison analysis detected significant differences across the types. The prevalences of the newly identified types were as follows: 78.2%, 8.8%, and 12.9% for type 1, type 2, and type 3, respectively. 73.9% of type 1 HRVA, 53.8% of type 2 HRVA, and 100% of type 3 HRVA had a concomitant ipsilateral NP. Prediction of the HRVA types by the K-means clustering has been evaluated. Screw placement techniques for each type are proposed and discussed.CONCLUSIONWe present the first classification system for the high-riding vertebral artery distinguishing three types based on the large homogenous cohort, which may serve as an adjunct to preoperative planning of C2 instrumentation. External validation of this classification scheme shall determine its further clinical utility.","PeriodicalId":22961,"journal":{"name":"The Spine Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ODI is used by surgeons to determine the initial status and monitor progress after surgery. Compiled ODI data enables comparisons between different surgical techniques. Degenerative lumbar spondylolisthesis (DLS) often causes symptoms such as back pain and neurogenic claudication affecting quality of life and activities of daily living captured by the ODI. Despite extensive studies on ODI changes after spinal surgery, little is known about the characteristics and changes in the different ODI subsections.PURPOSETo analyze the baseline characteristics and changes in total ODI and ODI subsections 2 years after elective lumbar surgery.STUDY DESIGNRetrospective analysis on patients prospectively enrolled who underwent spinal surgery for degenerative lumbar spondylolisthesis from 2016 to 2018. The ODI was assessed preoperatively and 2 years postoperatively.PATIENT SAMPLEA total of 265 patients were included in the study, 60% were female. The mean age of the patients was 67 ± 8 years, and the mean BMI was 30 ± 6 kg/m2.OUTCOME MEASURESThe analysis considered the differences in ODI scores before and after surgery, as well as the changes in all ODI subsections 2 years after elective lumbar surgery for DLS.METHODSThe analysis evaluated differences in ODI scores and variations in different subsections. Patients without an ODI follow-up at 2 years were excluded from the study. The study utilized the Wilcoxon Signed Rank Test for all pre-post paired samples. The Wilcoxon rank sum test was used for sex and procedure comparisons for overall ODI and ODI subsection analysis. Univariate linear regression was applied for overall and subsection specific ODI outcomes with age and BMI as independent variables, respectively. The statistical significance level was set at p&lt;0.05.RESULTSImprovement in ODI was observed in 242 patients (91%). The highest baseline disability values were found for the questions regarding pain intensity (3.4 ± 1.3), lifting (3.2 ± 1.9), and standing (3.4 ± 1.3). The lowest preoperative functional limitations were observed in sleeping (1.6 ± 1.3), personal care (1.6 ± 1.4), traveling (1.6 ± 1.2) and sitting (1.5 ± 1.4). At the 2-year follow-up, there was significant improvement in all questions and the overall ODI (all p&lt;0.001). The ODI subsections that showed the greatest absolute improvements were changing degree of pain (-2.6), with 89% of patients experiencing improvement, standing (-2.4) with 87% of patients experiencing improvement, and pain intensity (-2.1) with 81% of patients experiencing improvement.
