ABSTRACT
Methods@#We analyzed 124 operated CSM cases from March 2019 to April 2021 for preoperative clinical features, cervical sagittal radiographic parameters, and magnetic resonance imaging (MRI) signal intensities (SI). The risk factors associated with missing the MCID (poor outcome) on mJOA at the final follow-up were identified using binary logistic regression. Multivariate analysis was used to find significant risk factors, and odds ratios (OR) were computed. @*Results@#A total of 110 men (89.2%) and 14 women (10.8%) with an average age of 53.5±13.2 years were included in the analysis. During the last follow-up, 89 cases (72.1%) achieved MCID (meaningful gains following surgery) while 35 (27.9%) could not. The final model identified the following parameters as significant risk factors for poor outcome: increased duration of symptoms (OR, 6.77; p=0.001), lower preoperative mJOA scale (OR, 0.75; p=0.029), the presence of multilevel T2-weighted (T2W) MRI SI (OR, 4.79; p=0.004), and larger change in cervical sagittal vertical axis (ΔcSVA) (OR, 1.06; p=0.013). Also, an increase in cSVA postoperatively correlated with a reduced functional recovery rate (r=−0.4, p<0.001). @*Conclusions@#Surgery for CSM leads to significant functional benefits. However, poorer outcomes are observed in cases of greater duration of symptoms, higher preoperative severity with multilevel T2W MRI SI, and a larger increase in the postoperative cSVA (sagittal imbalance).
ABSTRACT
Methods@#Using the hospital records and imaging database obtained from January 2014 to January 2020, this study retrospectively analyzed patients who underwent surgery for Pott’s spine and met the eligibility criteria. @*Results@#This study included 230 patients with a mean±standard deviation age of 47.7±18.1 years (109 males, 121 females). The Visual Analog Scale score, Oswestry Disability Index, and Cobb angle were significantly improved in these patients (p<0.001). Patients who underwent anterior reconstruction had a greater correction in Cobb angle postoperatively (p=0.042) but also had a greater blood loss (p=0.04). During the follow-up, they experienced a significant loss of correction compared with those who only underwent transpedicular decompression (p=0.026). Nevertheless, patients who underwent anterior reconstruction using mesh/PEEK cages showed no significance difference in the clinical or radiological outcomes. @*Conclusions@#Transpedicular decompression used in the surgical management of Pott’s spine showed favorable clinical and radiological outcomes. The additional use of anterior reconstruction obtained equivalent clinical outcomes but resulted in excessive blood loss. Meanwhile, the use of mesh/PEEK cage for anterior reconstruction did not affect the clinical and radiological outcomes.
