Study Design: Case report. Objectives: We report a case of lumbar spine fracture sustained during a virtual reality (VR) game. Summary of Literature Review: As video games have evolved, so have video game-related injuries. Because VR gamers wear headsets that block their ability to see the surroundings, it is thought that VR gamers are more at risk than previous video gamers. However, no VR game–related injuries have yet been reported. Materials and Methods : A 53-year-old man sustained a lumbar spine fracture during a VR game. Because the game simulated his fall from a building, he lost his balance and fell down on the floor. A compression fracture of the third lumbar vertebra was demonstrated by imaging and conservative management using rigid orthosis was done. Results: At a 1-year follow up, computed tomography showed complete bone union of L3. Conclusions: Even though the activity was simulated, the resulting injury was all too real. Clinicians should never underestimate the risk of VR game injuries and should consider them in the differential diagnosis of musculoskeletal injuries.

Background: Patients with central lumbar spinal stenosis (CLSS) complain of not only the lower leg symptoms but also low back pain (LBP) simultaneously in many cases. Therefore, patients who undergo decompressive surgery expect recovery from LBP as well as lower leg symptoms, and surgeons who perform decompression surgery are making efforts to improve both symptoms. The objective of this study is to investigate whether decompression surgery can improve low back pain and symptoms of lower limb pain in patients with one level central lumbar spinal stenosis.Methods: The present study included 39 patients who had findings of central lumbar spinal stenosis and underwent decompression surgery due to its corresponding claudication and lower leg radiating pain complaints from 2013 to 2018. Their pain (lower leg radiating pain and low back pain) and functional outcomes (Oswestry Disability Index (ODI), Roland–Morris Disability Questionnaire (RMDQ), and Short Form-36 (SF-36)) were evaluated before surgery and 6 and 12 months after surgery.Results: Mean lower leg radiating pain continuously showed statistically significant improvement (p < 0.05, p = 0.003); however, the clinical significance of differences above minimum clinically important difference (MCID) was up to 6 months. Mean low back pain was 4.72 ± 3.40 before surgery, 2.33 ± 2.27 at 6 months after surgery, and 2.21 ± 2.02 at 12 months after surgery, showing statistically and clinically significant improvement (p < 0.05) up to 6 months after surgery, after which there were no findings of improvement. Conclusion: Decompression surgery for patients with central lumbar spinal stenosis showed clinically significant improvements in lower leg radiating pain and low back pain up to 6 months after surgery and continuous improvements in lower leg radiating pain up to 12 months, but there was no continuous improvement in LBP.
背景:中枢性腰椎管狭窄症(CLSS)患者在许多病例中不仅有下肢症状，而且同时有腰痛(LBP)。因此，接受减压手术的患者期望从LBP和下肢症状中恢复，而进行减压手术的外科医生正在努力改善这两种症状。本研究的目的是探讨减压手术是否可以改善一节段中央腰椎管狭窄患者的腰痛和下肢疼痛症状。方法:本研究纳入2013年至2018年39例因相应的跛行和下肢放射痛主诉而出现中央腰椎管狭窄并行减压手术的患者。术前、术后6个月和12个月评估患者的疼痛(下肢放射痛和腰痛)和功能结局(Oswestry残疾指数(ODI)、Roland-Morris残疾问卷(RMDQ)和SF-36)。结果:下肢放射痛持续平均改善有统计学意义(p < 0.05, p = 0.003);而最小临床重要差异(minimum clinical important difference, MCID)以上差异的临床意义可达6个月。平均腰痛术前为4.72±3.40，术后6个月为2.33±2.27，术后12个月为2.21±2.02，术后6个月均有显著改善(p < 0.05)，术后无明显改善。结论:中枢性腰椎管狭窄症患者行减压手术后，术后6个月下肢放射痛和腰痛均有临床显著改善，术后12个月下肢放射痛持续改善，但LBP无持续改善。

Study Design: Retrospective pilot study Objectives: To compare and analyze the rate and risk factors of implant failure according to the use of solid pedicle screws or cement augmented cannulated pedicle screws in lumbar fusion surgery. Summary of Literature Review: In previous studies, the use of cement augmented cannulated pedicle screws was found to improve the pull-out strength and to reduce the risk of implant failure in patients with osteoporosis. However, the clinical risk factors for implant failure have not been established. Materials and Methods: From January 2016 to December 2018, 177 patients with spine fracture and degenerative thoracolumbar disease were included in a retrospective study, and the patients underwent spinal fusion surgery using pedicle screws. Solid pedicle screws were used in 118 patients and cement augmented cannulated pedicle screws were used in 59 patients. During the follow-up period, simple radiography and computed tomography were performed to evaluate cases of implant failure, including pedicle screw loosening, migration, and pull-out, and to analyze risk factors for implant failure. Implant failures were observed in 21 patients (11.9%, 21/177) during the follow-up period. Of the 21 patients with implant failure, 18 were in the solid pedicle screw group (15.3%, 18/118), and 3 patients were in the cement augmented cannulated pedicle screw group (5.1%, 3/59). The difference was statistically significant (p<0.05). Age over 65 years, osteoporosis, autoimmune disease (rheumatoid arthritis, systemic lupus erythematosus, etc.), chronic kidney disease, and steroid use (<0.05) were statistically significantly more common in patients who experienced implant failure. In a multiple logistic regression analysis, age over 65 (odds ratio, 4.47; p=0.032), osteoporosis (odds ratio, 3.68; p=0.017), autoimmune disease (odds ratio, 3.59; p=0.039), and chronic kidney disease (odds ratio, 4.67; p=0.043) were statistically significant risk factors for implant failure. Conclusions: Patients underwent thoracolumbar fusion who were over 65 years of age, had osteoporosis, chronic kidney disease, or autoimmune disease showed a high implant failure rate. The use of cement augmented cannulated pedicle screws might be an effective method to significantly decrease the likelihood of implant failure in patients with these risk factors.

Study Design: Feasibility study. Objectives: To evaluate the association between L1 slope and thoracolumbar spinal parameters of sagittal balance in cases of osteoporotic vertebral fracture. Summary of Literature Review: Recently, interest has emerged in the sagittal parameters of the thoracolumbar spine in cases of osteoporotic vertebral fracture. Materials and Methods: Eighty-five patients were enrolled in this study, including 36 patients with recent osteoporotic vertebral fractures (group 1) and 49 patients who did not have vertebral fractures (group 2). Radiographic parameters including L1 slope, C7 plumb line (C7 PL), sagittal imbalance (C7 PL >50 mm), lumbar lordosis, thoracic kyphosis, pelvic tilt, S1 slope, local kyphotic angle were evaluated on standing lateral radiographs of the whole spine. We analyzed correlations between L1 slope and these parameters. Results: Of the sagittal parameters of the spine, the mean L1 slope, C7 PL, thoracic kyphosis, lumbar lordosis, S1 slope, pelvic tilt, and local kyphotic angle were 10.43°, 92.43 mm, 29.30°, 30.31°, 25.27°, 27.27°, 9.90° in group 1 and 9.41°, 68.50 mm, 20.09°, 23.25°, 22.03°, 31.43°, 8.21° in group 2, respectively. There were significant differences in thoracic kyphosis (p=0.01) and lumbar lordosis (p=0.04) between the two groups. L1 slope was positively correlated with thoracic kyphosis (r=0.46, p=0.01), lumbar lordosis (r=0.51, p=0.01), and local kyphotic angle (r=0.29, p=0.04) in group 1. Conclusions: These results suggest that L1 slope is a central indicator for the evaluation of thoracolumbar sagittal balance in osteoporotic vertebral fractures.

Study Design: Case report. Objectives: This case report presents a surgical technique used to perform vertebral anterior column stabilization in an elderly male patient who had recently been diagnosed with an uppermost instrumented vertebral fracture (IVF) at the site of previous posterior lumbar instrumented fusion (PIF). Summary of Literature Review: Although conservative treatment is also used for IVF, the proximal junction of PIF is an area where the compression load is concentrated biomechanically, so the uppermost IVF often requires surgical treatment. This may require fixation of extended segments and more surgical morbidity. Materials and Methods: A 73-year-old male patient who had undergone PIF from L2 to L5 more than 20 years previously was recently diagnosed with uppermost IVF without a traumatic event. He complained of persistent back pain even after 2 months of conservative treatment. He ultimately underwent percutaneous vertebroplasty through the parapedicular approach. Result: The patients showed a favorable outcome at a 1-year follow-up. Conclusions: Percutaneous vertebroplasty through the parapedicular approach for uppermost IVF at the site of a previous PIF might be a feasible and less invasive alternative.
