  • Study Design: Prospective observational study. Purpose: To determine the incidence of postoperative urinary retention (POUR) in patients undergoing elective posterior lumbar spine surgery and identify the risk factors associated with the development of POUR. Overview of Literature: POUR following surgery can lead to detrusor dysfunction, urinary tract infections, prolonged hospital stay, and a higher treatment cost; however, the risk factors for POUR in spine surgery remain unclear. Methods: A prospective, consecutive analysis was conducted on patients undergoing elective posterior lumbar surgery in the form of lumbar discectomy, lumbar decompression, and single-level lumbar fusions during a 6-month period. Patients with spine trauma, preoperative neurological deficit, previous urinary disturbance/symptoms, multiple-level fusion, and preoperative catheterization were excluded from the study. Potential patient- and surgery-dependent risk factors for the development of POUR were assessed. Univariate analysis and a multiple logistical regression analysis were performed. Results: A total of 687 patients underwent posterior lumbar spine surgery during the study period; among these, 370 patients were included in the final analysis. Sixty-one patients developed POUR, with an incidence of 16.48%. Significant risk factors for POUR were older age, higher body mass index (BMI), surgery duration, intraoperative fluid administration, lumbar fusion versus discectomy/decompression, and higher postoperative pain scores (p<0.05 for all). Sex, diabetes, and the type of inhalational agent used during anesthesia were not significantly associated with POUR. Multiple logistical regression analysis, including age, BMI, surgery duration, intraoperative fluid administration, fusion surgery, and postoperative pain scores demonstrated a predictive value of 92% for the study population and 97% for the POUR group. Conclusions: POUR was associated with older age, higher BMI, longer surgery duration, a larger volume of intraoperative fluid administration, and higher postoperative pain scores. The contribution of postoperative pain scores in the multiple regression analysis was a significant predictor of POUR.

  • The occurrence of traumatic hernia is rare. However, traumatic lumbar hernias are the most frequently occurring traumatic hernias. Superior lumbar hernias occur more frequently than inferior lumbar hernias, but for anatomical reasons, among traumatic lumbar hernias, inferior lumbar hernias occur more frequently than superior lumbar hernias. Repair of a lumbar hernia is very difficult. Mesh fixation to the bony part and general weakness of surrounding tissue make repair of a lumbar hernia tricky. A traumatic lumbar hernia was repaired using transfascial fixation around the defect to secure the mesh. This technique is another choice for a lumbar hernia technique.

  • Objective : There are differences in the clinical characteristics and surgical results between upper (L1-2 and L2-3) and lower (L3-4, L4-5, and L5-S1) lumbar disc herniations. We conducted this study to compare the clinical features and surgical outcomes between the two types of lumbar disc herniations. Methods : We retrospectively reviewed the clinical features of patients who underwent microdiscectomies from 2008 to 2012. We evaluated the clinical characteristics such as age, preoperative autonomic dysfunction, the presence or absence of previous lumbar surgery and fusion required during surgery. Visual Analogue Scale (VAS) scores about back pain and leg pain were evaluated preoperatively and at the final follow-up. Results : Upper lumbar group (n=15) was significantly older than lower lumbar group (n=148). The incidence of autonomic dysfunction was significantly higher in upper lumbar group. The number of patients with a previous lumbar surgery was significantly greater in upper lumbar group. There was no statistical significance for fusion required during surgery between two groups. Both groups showed a significant decrease in the VAS scores of leg pain. VAS scores of back pain were significantly decreased in lower lumbar group. But this was not seen in upper lumbar group. Both groups showed significant improvement of Oswestry Disability Index score. Conclusion : Upper lumbar group had different clinical characteristics from those of lower lumbar group and these include older age, a higher incidence of autonomic dysfunctions and a higher incidence of patients with previous lumbar surgery. There were no significant differences in surgical outcomes, except for back pain, between two groups.

  • Objective : Lumbar foraminal stenosis is an important etiology of lumbar radicular symptomatology and frequent causes of remained symptoms after decompressive surgery. This study was conducted to determine the precise clinical and radiologic diagnosis of lumbar foraminal stenosis, and to demonstrate thorough treatment by decompressive surgery using a minimally invasive technique. Methods : Seven patients with established unilateral lumbar foraminal stenosis according to clinical and radiologic diagnosis were retrospectively studied. All patients underwent combined interlaminar and paraisthmic procedure with partial facetectomy. The outcome of surgery was evaluated and classified into excellent, good, fair and poor. Results : The results were excellent in four patients, good in two, and fair in one during the follow-up. There were no surgery-related complications. Conclusion : Minimally invasive combined interlaminar and paraisthmic approach provides good outcome in carefully selected patients with symptomatic lumbar foraminal stenosis.

  • Objective : The objective of this study is to evaluate and compare the clinical results between classical open surgery and percutaneous endoscopic lumbar discectomy[PELD] in cases of extraforaminal lumbar disc herniation. Methods : We obtained the clinical data from 47 patients with extraforaminal lumbar disc herniations who underwent the open paramedian muscle-splitting approach or percutaneous endoscopic lumbar discectomy[PELD] between January 2001 and February 2004. This study consisted of patients with soft disc extraforaminal herniations. The patients were assessed with the visual analogue scale[VAS] and MacNab's criteria before surgery, just before discharge, and postoperative 1 year. Results : There were 25 cases in the open surgery group and 22 cases in the PELD group. The average operating time was $78{\pm}36.71\;min$ in the PELD group and $110{\pm}29.68\;min$ in the open surgery group. The mean hospital stay was $2.73{\pm}2.62$ days in the PELD group and $7.68{\pm}2.59$ days in the open surgery group. VAS decreased from $8.34{\pm}0.66$ to $1.29{\pm}2.27$ in the PELD group and from $8.40{\pm}1.40$ to $1.70{\pm}1.72$ in the open surgery group at the one-year follow-up. The success rate of PELD was 86.4%, compared with 80.0% for open surgery. However, there were no statistically significant difference between two groups for success rate and VAS. Conclusion : Although the success rates were similar in both groups, PELD is less invasive, faster, and safe procedure than open surgery for extraforaminal disc herniation in selected patients.

  • Objectives We are going to analyze patient's medical and Korean medicine use trends after lumbar surgery, and examine the percentage of use of Korean medicine after surgery and its relevance to the medical care outcome after lumbar surgery. Methods Using 3% patients' sample data of the Health Insurance Review and Assessment Service, two groups were compared the treatment progress of the Korean Medicine treatment group and the untreated group after lumbar surgery by hierarchical logistic regression analysis. After hierarchical logistic regression analysis(including propensity scores), two groups were compared after lumbar surgery, the Korean Medicine treatment group within 50days and untreated group within 50days. Results Lumbar surgery was performed in 2750 patients in 2015. It was 3.72 that the risk(odds ratio) of finished treatment of patients treated without Korean Medicine, compared to patients with Korean Medicine. It was 0.12 that the risk of continuing treatment(odds ratio) of patients treated with Korean Medicine within 50 days, compared to patients treatment more than 50 days. Conclusions The ratio of Korean Medicine treatment after lumbar surgery was 14.8%. The group that did not have Korean Medicine showed a higher possibility of treatment termination than the group who did not. Among the groups treated with Korean Medicine, the early treatment group was more likely to end treatment than the late treatment group. Considering various situations in the medical environment, further studies such as prospective studies and long-term data analysis are considered to be necessary.

  • Objective : Life expectancy for humans has increased dramatically and with this there has been a considerable increase in the number of patients suffering from lumbar spine disease. Symptomatic lumbar spinal disease should be treated, even in the elderly, and surgical procedures such as fusion surgery are needed for moderate to severe lumbar spinal disease. However, various perioperative complications are associated with fusion surgery. The aim of this study was to examine perioperative complications and assess risk factors associated with lumbar spinal fusion, focusing on geriatric patients at least 70 years of age in the Republic of Korea. Methods : We retrospectively investigated 489 patients with various lumbar spinal diseases who underwent lumbar spinal fusion surgery between 2003 and 2007 at our institution. Three fusion procedures and the number of fused segments were analyzed in this study. Chronic diseases were also evaluated. Risk factors for complications and their association with age were analyzed. Results : In this study, 74 patients experienced complications (15%). The rate of perioperative complications was significantly higher in patients 70 years of age or older than in other age groups (univariate analysis, p=0.001; multivariate analysis, p=0.004). However, perioperative complications were not significantly associated with the other factors tested (sex, comorbidities, operation procedures, fusion segments involved). Conclusion : Increasing age was an important risk factor for perioperative complications in patients undergoing lumbar spinal fusion surgery whereas other factors were not significant. We recommend good clinical judgment and careful selection of geriatric patients undergoing lumbar spinal fusion surgery.

  • Objective : To evaluate the role of anterior lumbar interbody fusion in treatment of failed back surgery syndrome, the authors retrospectively analyzed the result of anterior lumbar interbody fusion performed in our institute. Methods : Fifteen FBSS patients due to variable causes have been treated with anterior lumbar interbody fusion in our institute from April 1994 to June 1999. We analyzed clinical changes in 15 patients who were followed up for an average of 23 months. Results : The etiologies of FBSS were post operative discitis(6 cases), post operative instability(3 cases), post operative adhesion(5 cases), and recurrence(1 case). These fifteen FBSS patients were treated with anterior lumbar interbody fusion. The overall treatment outcome was satisfactory(excellent and good) in 11 cases. Three patients were slightly improved, but post operative low back pain was remained. One patient who had underwent nerve root injury due to pedicle screw insertion showed no improvement. Conclusion : We conclude that the anterior lumbar interbody fusion for FBSS seems to be safe and favorable treatment in selective patients, because low incidence of nerve injury risk and post-operative infection.

  • Background: Over the years, disc surgery has progressively evolved in the direction of decreasing trauma and its invasiveness. Conventional open surgery has many complications, such as scarring, instability, bleeding and a relative high mortality rate. Minimally invasive spinal surgery is now an alternative to a traditional discectomy. Herein, we present an operative technique, and the early results, for a percutaneous endoscopic lumbar discectomy in herniated lumbar disc disease. Methods: 43 patients, including 27 men and 16 women, with ages ranging from 18 to 66 years, were enrolled in this study. All the patients showed a protruded or extruded soft disc herniation at the lumbar level on magnetic resonance imaging and computed tomography. A percutaneous endoscopic lumbar discectomy was applied to the patients, and clinical responses evaluated using MacNab's criteria. Results: 40 patients were regarded as showing successful responses (93.1%), and there were no severe complications, such as a hematoma, nerve injury, postoperative dysesthesia or death. One patient underwent fusion surgery for remnant back pain six month later. Conclusions: We conclude that, in properly selected patients, a percutaneous endoscopic lumbar discectomy is a safe, noninvasive and effective treatment modality for herniated lumbar intervertebral disc disease.
