Aims. The escalating demand for medical resources to address spinal diseases as society ages is an issue that requires careful evaluation. However, few studies have examined trends in spinal surgery, especially unscheduled hospitalizations or surgeries performed after hours, through large databases. Our study aimed to determine national trends in the number of spine surgeries in Japan. We also aimed to identify trends in after-hours surgeries and unscheduled hospitalizations and their impact on complications and costs. Methods. We retrospectively investigated data extracted from the Diagnosis Procedure Combination database, a representative inpatient database in Japan. The data from April 2010 to March 2020 were used for this study. We included all patients who had undergone any combination of

Prolonged length of stay (LOS) is a significant contributor to the variation in surgical health care costs and resource utilization after elective spine surgery. The primary goal of this study was to identify patient, surgical and institutional variables that influence LOS. The secondary objective is to examine variability in institutional practices among participating centers. This is a retrospective study of a prospectively multicentric followed cohort of patients enrolled in the CSORN between January 2015 and October 2020. A logistic regression model and bootstrapping method was used. A survey was sent to participating centers to assessed institutional level interventions in place to decrease LOS. Centers with LOS shorter than the median were compared to centers with LOS longer than the median. A total of 3734 patients were included (979 discectomies, 1102
Spinal stenosis is a condition resulting in the compression of the neural elements due to narrowing of the spinal canal. Anatomical factors including enlargement of the facet joints, thickening of the ligaments, and bulging or collapse of the intervertebral discs contribute to the compression. Decompression surgery alleviates spinal stenosis through a

Introduction. Pulmonary Tuberculosis (TB) can be detected by sputum cultures. However, Extra Pulmonary Spinal Tuberculosis (EPSTB), diagnosis is challenging as it relies on retrieving a sample. It is usually discovered in the late stages of presentation due to its slow onset and vague early presentation. Difficulty in detecting Mycobacterium Tuberculosis bacteria from specimens is well documented and therefore often leads to culture negative results. Diagnostic imaging is helpful to initiate empirical therapy, but growing incidence of multidrug resistant TB adds further challenges. Methods. A retrospective analysis of cases from the Infectious Disease (ID) database with Extra Pulmonary Tuberculosis (EPTB) between 1. st. of January 2015 to 31. st. of January. Two groups were compared 1) Culture Negative TB (CNTB) and 2) Culture Positive TB (CPTB). Audit number was. Results. 31 cases were identified with EPSTB. 68% (n=21) were male. 55% (n=17) patients were Asian, (19% (n=6) were black and 16% (n=5) were of white ethnicity. 90.4% (n=28) patients presented with isolated spinal TB symptoms. No patient had evidence of HBV/HCV/HIV infections. CPTB Group was 51.6% (n=16) compared to CNTB Group with 48.4% (n=15) 48% (15) lumbar involvement, 42% (13) thoracic and 10% (3) cervical. 38.7% (12) patients presented with late neurology, equally in both groups. 56% CPTB patients showed signs of vertebral involvement on plain radiograph compared to 13.3% in CNTB patients. 68.7% CPTB patients had pathological changes or paraspinal collections seen on CT scan compared to 53.3% of CNTB patients. 81% of CPTB showed positive MRI findings compared to 86% in CNTB. Both groups were treated with Anti-TB medications according to local guidelines. 83% patients were followed up till the end of the treatment course. 22.5% (n=7) patients had Ultrasound guided aspiration. 29% (n=9) patients underwent surgical intervention. 3 patients had

Purpose: Cervical laminoplasty has been used for the treatment of cervical arthrosic myelopathy in Japan. The purpose of this work was to assess clinical and radiological outcome at more than two years follow-up. Material: Thirty-one patients underwent laminoplasty of three levels or more for cervical arthrosic myelopathy and were reviewed more than two years after surgery. Methods: The Japanese Orthopaedic Association score was used to assess function preoperatively and at last follow-up. Preoperative and last follow-up standard strict lateral and flexion and extension x-rays of the cervical spine were available for all patients. The curvature was assessed on the lateral view in the neutral position (C2–C7 Cobb angle). Overall mobility was assessed on the dynamic views. Results: The mean preoperative score was 9.7, improving to 138 at last follow-up (p <
0.0001, paired t test). Mean relative gain was 52.9%. The mean Cobb angle was 17° preoperatively and 8.9° at last follow-up. Cervical spine curvature and overall mobility had no influence on the score at last follow-up. The postoperative Cobb score was only influenced by the preoperative angle (p <
0.0001). There were no reoperations for instability. Discussion: Guigui has demonstrated that mean loss of cervical lordosis in a series of extended
