Liu C, Guo C, Meng F, Zhu Z, Xia W, Liu H. Perioperative risk factors related to complications of lumbar spine fusion surgery in elderly patients. BMC Musculoskelet Disord 2023; 24:573. [PMID: 37452304 PMCID: PMC10347777 DOI: 10.1186/s12891-023-06689-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 07/03/2023] [Indexed: 07/18/2023] Open
Abstract
PURPOSE To analyze the perioperative risk factors related to lumbar spine fusion surgery in elderly patients. METHODS 202 elderly patients (age range 77-92 years old) who have underwent lumbar spinal fusion surgeries between January 2019 and June 2021 were retrospectively investigated. Information of age, sex, comorbidity, fixation segments, operation time, surgical blood loss and perioperative complications during hospitalization were collected. Risk factors for complications were analyzed. Student's t-test, chi-square test, Mann-Whitney U‑test and multivariate generalized linear models were used. RESULTS In this study, 31 patients presented complications (15.3%) in these elderly patients with an average age of 79.1 years, including 1 patient with intraoperative complication and 30 patients with postoperative complications; and 2 out of 31 patients (1%) died. The elderly patients were divided into group A (24 patients) with major postoperative complications and group B (178 patients) without major postoperative complications. Major postoperative complications were significantly associated with age (univariate analysis, t = 3.92, P < 0.001; multivariate analysis, OR = 1.323, 95%CI 1.126-1.554, P = 0.001), but not significantly associated with other factors tested (sex, comorbidity, fixation segments, operation time, surgical blood loss). Then 173 patients (range 77-81 years) were selected and the rate of major postoperative complications of each age from 78 to 81 years was compared with that of 77 years patients, respectively. We found that the ratios of complications at 80 years (OR = 10.000, P = 0.019) and 81 years (OR = 10.000, P = 0.009) were higher than the ratio at 77 years. CONCLUSIONS Although with great progress of medical technology, increasing age was still the independent risk factor for major postoperative complications in elderly patients undergoing lumbar spinal fusion surgery. As for the incidence of major postoperative complications, 80 and 81 years old patients was 10 folds higher than that of 77 years old patients, reminding us to pay more attention to 80 years old and even older patients.

Abstract
BACKGROUND We compare the differences in the efficacy of percutaneous transforaminal endoscopic diskectomy (PTED) between the younger (age <60 years) and older (age ≥60 years) patients with lumbar disk herniation (LDH). METHODS From December 2016 to December 2017, 128 patients with symptomatic LDH underwent PTED and were followed up. Forty-four 60 years old and above, including 19 males and 25 females with an average age of 68.7 (61-82) years, were classified as the elderly age group. Eighty-four patients younger than 60 years were classified as the young age group, which included 48 males and 36 females with an average age of 44.7 (16-58) years. The visual analog scale (VAS) scores, Japanese Orthopaedic Association (JOA) scores, and satisfaction rates of the two groups before and after surgery were compared. RESULTS The operation was completed successfully in both groups. The average follow-up times of the elderly and young age groups were 18.47 ± 2.62 (12-23) and 17.90 ± 3.27 (12-23) months, respectively. One patient in the young age group had recurrence 7 months after surgery, and the symptoms were relieved after PTED was performed again. Two patients with nerve root injury after surgery in the young age group completely recovered after 2 months of conservative treatment. There were no significant surgical complications in the elderly age group. There was no significant difference in postoperative VAS, JOA, and MacNab scores between the two groups. The MacNab scores in the elderly age group were excellent for 28 patients, good for 10 patients, and fair for 6 patients; the satisfaction rate was 86.3%. In the young age group, scores were excellent for 63 patients, good for 14 patients, fair for 5 patients, and poor for 2 patients; the satisfaction rate was 91.7%. CONCLUSION The clinical effectiveness of PTED for treatment of LDH in both elderly and young patients is satisfactory. Age is not a predictor of poor outcomes of PTED.

Abstract
STUDY DESIGN Retrospective study. PURPOSE This study aimed to evaluate the incidence, characteristics, and risk factors for clinical L5-S1 adjacent segment degeneration (ASD) after L5 floating lumbar fusion. OVERVIEW OF LITERATURE ASD is known to occur after lumbar spine fusion at a certain frequency. Several studies on radiological L5- S1 ASD have been reported. However, there are only a few studies on L5-S1 ASD with clinical symptoms, including back pain and/or radiculopathy. METHODS In total, 306 patients who received L5 floating lumbar fusion were included in this study. Clinical L5-S1 ASD was defined as newly developed radiculopathy in relation to the L5-S1 segment. Patients' medical records and imaging data were retrospectively analyzed. The risk factors for clinical ASD were assessed by an inverse probability of treatment weighting-adjusted logistic regression analysis. RESULTS Clinical L5-S1 ASD occurred in 17 patients (5.6%). The mean onset time of L5-S1 ASD was 12.9±7.5 months after the primary surgery. Among these patients, 10 (58.8%) presented with clinical L5-S1 ASD within 12 months. Reoperation was performed in three patients (1.0%). The severity of L5-S1 disk degeneration did not affect the occurrence of L5-S1 ASD. Logistic regression analysis showed that the number of fusion levels was a significant risk factor for clinical L5-S1 ASD. CONCLUSIONS The incidence and characteristics of clinical L5-S1 ASD after L5 floating lumbar fusion were retrospectively investigated. This study established that the number of fusion levels was a significant candidate factor for clinical L5-S1 ASD. Careful clinical follow-up is deemed necessary after L5 floating lumbar fusion surgery, especially for patients who received multiple-level fusions.

Abstract
Introduction Lumbar discectomy is a common and effective treatment for symptomatic disk herniation. It has been suggested that lumbar discectomy in older patients may result in poorer clinical outcomes and lesser satisfaction. The purpose of this study was to assess age-related difference in patient reported outcomes of patients undergoing lumbar discectomy for chronic low back and radicular pain. Materials and methods Patients with chronic lumbar radiculopathy without neurological deficit underwent non-urgent single level lumbar discectomy in our institution between 2014 and 2017. Pain level (using VAS score), Oswestry Disability Index, and SF-12 scores were retrospectively reviewed and compared between younger patients (<60 years, group 1) and older patients (>60 years, group 2). Results Seventy-three patients, aged between 34–76 years participated in this study. VAS, ODI, and SF-12 scores improved significantly after the surgery for each group (P < .01). When comparing between the groups, no significant differences in the outcomes measured were found after the surgery in both early post-operative follow-up and late post-operative follow-up (P > .05). Discussion Elderly patients undergoing lumbar discectomy report a significant reduction in VAS, ODI, and SF-12 scores justifying the procedure. Conclusion Lumbar discectomy improved function and decreased pain level to similar extent in both younger and older patients suffering from radicular symptoms related to lumbar disc herniation.

Abstract
The purpose of this study was to investigate the effectiveness of early (<72 h) versus late (≥72 h) decompression surgery after the onset of drop foot caused by root disorder in lumbar degenerative diseases (LDDs). Data were included from 60 patients who underwent decompression surgery for drop foot caused by LDDs, including lumbar disk herniation or lumbar spinal stenosis. The primary outcome was ordinal change in the manual muscle test (MMT) at 2 years follow-up. Secondary outcomes included changes in the Japanese Orthopedic Association's (JOA) score. The early- and late-stage surgery groups included 20 and 40 patients with mean durations from the onset of drop foot to operation of 0.8 days (range, 0-3 days) and 117.1 days (range, 10-891 days), respectively. There was no significant difference (p = 0.33) between the early- and late-stage surgery groups in the improvement of MMT scores to >4 (90% versus 80%, respectively). However, more patients in the early-stage group achieved an MMT score >5 compared with those in the late-stage surgery group (80% versus 45%; p = 0.03). Furthermore, the recovery rate of JOA scores was significantly higher in the early-stage (89.1%) compared with the late-stage surgery group (68.6%; p < 0.001). Early decompression surgery produced better neurological recovery; however, an improvement of >4 in the MMT score was achieved in 80% of cases with late decompression.

Abstract
Introduction In this study we are aiming to evaluate the changes of serum serotonin and its association with pain in patients suffering from chronic low back pain before and after lumbar discectomy surgery. Patients and Methods A prospective study was performed on the patients referring to the outpatient clinic in Besat hospital, Hamadan University of Medical Sciences, Hamadan, Iran, during 2016. A 2 mL fasting blood sample was collected from each patient at preoperative day 1 and postoperative day 14 and they were measured for level of serum serotonin. Besides, all patients were asked for severity of their low back pain in preoperative day 1 and postoperative day 14 and scored their pain from zero to ten using a Numerical Rating Scale. Results Forty patients with the mean age of 47 ± 13 yrs/old (range 25–77) including 15 (37.5%) males were enrolled into the study. The overall mean score of preoperative pain was significantly decreased from 7.4 ± 2.18 (range 4–10) to the postoperative pain score 3.87 ± 2.92 (range 0–10) (P < .001). The overall levels of pre- and postoperative serum serotonin were 3.37 ± 1.27 (range 1.1–6.4) and 3.58 ± 1.32 (range .94–7.1) ng/mL, respectively, with no significant difference (P = .09). The levels of pre- and postoperative serum serotonin were significantly higher in males and patients older than 50 yrs/old compared to the females and patients younger than 50 yrs/old, respectively (P = .03 and .005, respectively). A significant inverse correlation between the postoperative levels of pain and serum serotonin was observed (r = -.36 and P = .02). Conclusion A negative medium strength linear relationship may exist between the postoperative serum serotonin and low back pain.

Abstract
The authors retrospectively characterized the clinical outcomes of combining the Yeung endoscopic spine system (YESS) and transforaminal endoscopic surgical system (TESSYS) techniques during percutaneous transforaminal endoscopic discectomy (PTED) to treat multilevel lumbar disc herniation.PTED using both YESS and TESSYS was performed on 52 patients with multilevel lumbar disc herniations who had shown no apparent response to previous conservative treatments. Postsurgical follow-ups were conducted at weeks 1, 26, and 48. Patients' preoperative and postoperative performances were assessed by modified MacNab classification, Japanese Orthopedic Association (JOA) scores, Oswestry disability index (ODI), and visual analog scale (VAS), and compared with 34 and 45 patients who were treated only by YESS and TESSYS, respectively.The postsurgery surgeon-performed assessment showed satisfactory results in 98% of the YESS + TESSYS-treated cases. The average operative time was 116 ± 23 minutes, intraoperative bleeding was 19 ± 12 mL, and bed stay was 3 days. No complications occurred, including infection, nerve injury, or spinal canal hematoma. One week after surgery, the modified MacNab classifications of the patients were excellent in 45, good in 6, fair in 1, and poor in 0 (98% were excellent or good). JOA, ODI, and VAS scores for low back pain significantly improved relative to the preoperative assessment (P < .01) and had remained stable at 26 and 48 weeks.PTED that combined YESS and TESSYS techniques, depending on the predominant type of lumbar disc herniation at individual levels, is safe, minimally invasive, and effective.

Abstract
BACKGROUND Lumbar decompression for disc herniation is frequently performed on elderly patients, and this trend will continue as the population ages. Clinical reports on the complications of lumbar discectomy show good results and cost effectiveness in young or middle-aged patients. OBJECTIVE To assess and compare the morbidity of single-level lumbar disc surgery for radicular pain in a cohort of patients greater than 80 yr of age to that of a middle-aged cohort. METHODS A total of 9451 patients who received a single-level lumbar decompression procedure for disc displacement without myelopathy were retrospectively selected from a multicenter validated surgical database from the American College of Surgeons National Surgical Quality Improvement Program. A cohort with 485 patients greater than 80 yr of age (80+) was compared with a middle-aged cohort with 8966 patients between 45 and 65 yr. Preoperative comorbidity and postoperative outcome variables observed included mortality, myocardial infarction, return to the operating room, sepsis, deep vein thrombosis, transfusions, cardiac arrest necessitating cardiopulmonary resuscitation, coma greater than 24 h, urinary tract infection, acute renal failure, use of ventilator greater than 24 h, pulmonary embolism, pneumonia, wound dehiscence, and postoperative infection. RESULTS The preoperative comorbidities and characteristics were significantly different between the middle-aged and the 80+ cohorts, with the older cohort having many more preoperative comorbidities. There was statistically significantly greater postoperative morbidity among the 80+ cohort regarding pulmonary embolism (0.8% vs 0.2%, P = .037), intra/postoperative transfusion requirement (1.9% vs 0.7%, P = .01), urinary tract infection (1.2% vs 0.3%, P = .011), and 30-d mortality (0.4% vs 0.1%, P = .046). CONCLUSION In this large sample of patients who received a single-level lumbar decompression procedure for disc displacement without myelopathy, elderly patients, particularly with American Society of Anesthesiologists class 3 and 4, had a statistically significant increase in morbidity and mortality, but the overall risk of complications remains low.

Abstract
BACKGROUND CONTEXT Surgical treatment of lumbar disc herniation (LDH) may lead to different outcomes in young, middle-aged, and elderly patients. However, no study has, by the same data ascertainment, evaluated referral pattern, improvement, and outcome in different age strata. PURPOSE This study aimed to evaluate referral pattern and outcome in patients of different ages surgically treated because of LDH. STUDY DESIGN This is a register study of prospectively collected data. PATIENT SAMPLE In SweSpine, the national Swedish register for spinal surgery, we identified 11,237 patients who between 2000 and 2010 had their outcome of LDH surgery registered in pre-, per-, and 1-year postoperative evaluations. OUTCOME MEASURES The data collected included age, gender, smoking habits, walking distance, preoperative duration and degree of back and leg pain, consumption of analgesics, quality of life in the patient-reported outcome measure (PROM) Short-Form 36 (SF-36) and EuroQol 5 dimensions (EQ5D), disability in the Oswestry Disability Index, operated level, type of surgery, and complications. METHODS We compared the outcome in patients within different 10-year age strata. IBM SPSS Statistics 22 was used in the statistical calculations. No funding was obtained for this study. The authors have no conflicts of interest to declare. RESULTS Patients in all ages referred to surgery had inferior PROM data compared with published normative age-matched PROM data. Referral to LDH surgery demanded of each 10-year strata statistically significantly more pain, lower quality of life, and more disability (all p<.001). Surgery markedly improved quality of life and reduced disability in all age groups (all p<.001), but with statistically significantly less PROM improvement with each older 10-year strata (all p<.001). This resulted in statistically significantly inferior PROM values for pain, quality of life, and disability postoperatively for each 10-year strata (all p<.001). There were also more complications (p<.001) with each 10-year older strata. CONCLUSIONS In general, older patients referred to LDH surgery have statistically significantly inferior PROM scores, improve less, and reach inferior PROM scores postoperatively. The clinical relevance must however be questioned because most patients reach, independent of age group, the defined level for a successful outcome, and the patient satisfaction rate is high.

[PMID: 27497886 DOI: 10.1016/j.spinee.2016.08.003] [Citation(s) in RCA: 61] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2016] [Revised: 06/24/2016] [Accepted: 08/02/2016] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Sciatica is often caused by a herniated lumbar intervertebral disc. When conservative treatment fails, a lumbar discectomy can be performed. Surgical treatment via lumbar discectomy is not always successful and may depend on a variety of preoperative factors. It remains unclear which, if any, preoperative factors can predict postsurgical clinical outcomes. PURPOSE This review aimed to determine preoperative predictors that are associated with postsurgical clinical outcomes in patients undergoing lumbar discectomy. STUDY DESIGN This is a systematic review. METHODS This systematic review of the scientific literature followed the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. MEDLINE and PubMed were systematically searched through June 2014. Results were screened for relevance independently, and full-text studies were assessed for eligibility. Reporting quality was assessed using a modified Newcastle-Ottawa Scale. Quality of evidence was assessed using a modified version of Sackett's Criteria of Evidence Support. No financial support was provided for this study. No potential conflict of interest-associated biases were present from any of the authors. RESULTS The search strategy yielded 1,147 studies, of which a total of 40 high-quality studies were included. There were 17 positive predictors, 20 negative predictors, 43 non-significant predictors, and 15 conflicting predictors determined. Preoperative predictors associated with positive postoperative outcomes included more severe leg pain, better mental health status, shorter duration of symptoms, and younger age. Preoperative predictors associated with negative postoperative outcomes included intact annulus fibrosus, longer duration of sick leave, worker's compensation, and greater severity of baseline symptoms. Several preoperative factors including motor deficit, side and level of herniation, presence of type 1 Modic changes and degeneration, age, and gender had non-significant associations with postoperative clinical outcomes. CONCLUSIONS It may be possible for certain preoperative factors to be targeted for clinical evaluation by spine surgeons to assess the suitability of patients for lumbar discectomy surgery, the hope being to thereby improve postoperative clinical outcomes. Prospective cohort studies are required to increase the level of evidence with regard to significant predictive factors.

Abstract
Background and purpose - The outcome of surgical treatment of lumbar disc herniation (LDH) has been thoroughly evaluated in middle-aged patients, but less so in elderly patients. Patients and methods - With validated patient-reported outcome measures (PROMs) and using SweSpine (the national Swedish Spine Surgery Register), we analyzed the preoperative clinical status of LDH patients and the 1-year postoperative outcome of LDH surgery performed over the period 2000-2012. We included 1,250 elderly patients (≥ 65 years of age) and 12,840 young and middle-aged patients (aged 20-64). Results - Generally speaking, elderly patients were referred for LDH surgery with worse PROM scores than young and middle-aged patients, they improved less by surgery, they experienced more complications, they had inferior 1-year postoperative PROM scores, and they were less satisfied with the outcome (with all differences being statistically significant). Interpretation - Elderly patients appear to have a worse postoperative outcome after LDH surgery than young and middle-aged patients, they are referred to surgery with inferior clinical status, and they improve less after the surgery.

Abstract
INTRODUCTION Epidural steroid is an important modality in the conservative management of prolapsed lumbar disc and is being used for over 50 years. However, controversy still persists regarding their effectiveness in reducing the pain and improving the function with literature both supporting and opposing them are available. AIM To study the efficacy of epidural steroid injection in the management of pain due to prolapsed lumbar intervertebral disc and to compare the effectiveness between caudal, transforaminal and interlaminar routes of injection. MATERIALS AND METHODS A total of 152 patients with back pain with or without radiculopathy with a lumbar disc prolapse confirmed on MRI, were included in the study and their pre injection Japanese Orthopaedic Association (JOA) Score was calculated. By simple randomization method (picking a card), patients were enrolled into one of the three groups and then injected methyl prednisone in the epidural space by one of the techniques of injection i.e. caudal, transforaminal and interlaminar. Twelve patients didn't turn up for the treatment and hence were excluded from the study. Remaining 140 patients were treated and were included for the analysis of the results. Eighty two patients received injection by caudal route, 40 by transforaminal route and 18 by interlaminar route. Post injection JOA Score was calculated at six month and one year and effectiveness of the medication was calculated for each route. The data was compared by LSD and ANOVA method to prove the significance. Average follow-up was one year. RESULTS At one year after injecting the steroid, all three routes were found to be effective in improving the JOA Score (Caudal route in 74.3%, transforaminal in 90% and interlaminar in 77.7%). Transforaminal route was significantly more effective than caudal (p=0.00) and interlaminar route (p=0.03) at both 6 months and one year after injection. No significant difference was seen between the caudal and interlaminar route (p=0.36). CONCLUSION The management of low back pain and radicular pain due to a prolapsed lumbar intervertebral disc by injecting methyl prednisone in epidural space is satisfactory in the current study. All three injection techniques are effective with the best result obtained by transforaminal route.

Abstract
PURPOSE Outcome after lumbar disc herniation (LDH) surgery in middle-aged patient is usually reported to fulfill the criteria for successful outcome. It is also known that women in these years have an inferior outcome compared to men. This study evaluates whether the same gender differences exist in elderly. METHOD In the national Swedish register for spine surgery (SweSpine) we identified 1668 patients ≥65 years. 1250 of these patients had both pre- and 1-year postoperative data registered, 53 % males with mean age 70.6 ± 5.0 (mean ± SD) and 47 % females with mean age 71.3 ± 5.2. All were surgically treated due to LDH between 2000 and 2012. RESULTS Before surgery both men and women had severe impairment, compared to normative data, in all patient-reported outcome measures (PROMs), with women having inferior status to men. Improvement by surgery was similar in both genders but neither of them reached normative values in quality of life as compared to normative age-matched individuals. As a consequence of this women 1 year after surgery had more back and leg pain, higher consumption of analgesics, greater impairment in walking distance and inferior scoring in virtually all registered PROMs compared to men (all p < 0.005). In spite of this women were as satisfied with the surgical outcome as the men. CONCLUSION Elderly women with LDH surgery report inferior outcome compared to males, mainly as a result of being referred to surgery with an inferior status but are despite this as satisfied with outcome as the men.

Abstract
Study Design Case report. Objectives To describe a case of delayed-onset spinal hematoma following the breakage of a spinal epidural catheter. Methods The authors describe the clinical case review. Results A 64-year-old woman had undergone epidural anesthesia 18 years before she was referred to our hospital because of lower-back pain and lower neurologic deficit with leg pain. The clinical examination showed the presence of a fragment of an epidural catheter in the thoracolumbar canal, as assessed by computed tomography, and a spinal hematoma that compressed the spinal cord at the same spinal level, as assessed by magnetic resonance imaging. Surgical removal of the epidural catheter and decompression surgery were performed. The patient exhibited substantial clinical improvement 1 month after surgery; she achieved a steady gait without the need for a cane and had no leg pain. Conclusion This is the first report of delayed onset of spinal hematoma following the breakage of an epidural catheter. Generally, when the breakage of an epidural catheter occurs without symptoms, follow-up alone is recommended. However, because spinal hematoma might exhibit a late onset, the possibility of this complication should be considered when deciding whether to remove the catheter fragment. We believe that in our patient, there could be a relationship between the catheter fragment and subdural hematoma, and catheter breakage could have been a risk factor for the spinal hematoma.

Abstract
PURPOSE The purpose of this study was to evaluate the efficacy of transforaminal endoscopic lumbar discectomy (TELD) in the treatment of lumbar disc herniation (LDH) and to identify the relationship between TELD efficacy and age. METHODS A total of 207 consecutive LDH patients who had undergone TELD with the THESSYS system from January 2013 to September 2014 were divided into two groups on the basis of their age, with 108 cases in the ≤ 45-year-old age group and 99 cases in the >45-year-old group. The Oswestry Disability Index (ODI) was used to quantify the pain relief. The degree of pain and disability were measured on the basis of the visual analog scale (VAS) and the modified MacNab criteria. Complications, duration of hospital stay, surgical costs, and operation time were recorded and compared between the two groups. Spearman's coefficient of rank correlation was used to assess the learning curves for TELD. RESULTS The mean pre-operative and postoperative VAS and ODI scores significantly improved in both age ≤ 45 group and age >45 group, with no significant differences between them. In age ≤45 group, 56 % had excellent outcomes, 28 % good, 14 % fair, and 3 % poor. In the age >45 group, 51 % had excellent outcomes, 20 % good, 25 % fair, and 4 % poor. The average lengths of hospital stay for the age ≤ 45 group and age >45 group were 6.8 and 8.4 days, respectively. The mean time to return to work or normal activities was ten days for the age ≤ 45 group and 15 days for the age >45 group. The mean operative time for the age ≤ 45 group was 94 minutes and that for age >45 group was 97 minutes. The surgical cost of age ≤ 45 group was 15,480 RMB, which was lower than the 16,381 RMB of age >45 group. A total of 14 patients in the age ≤ 45 group and 13 patients in age >45 group used analgesic medications. Three and five recurrences were reported in the age ≤ 45 group and age >45, respectively. The steep learning curves of operative time plotted against the number of surgeries conducted suggest that the TELD technique can be mastered quickly in terms of reducing the duration of operation. CONCLUSIONS The efficacy of TELD is relatively good for the selected young and elderly patients in this study. Therefore, age is not a predictor of TELD surgery-related outcomes.

Abstract
Study Design A retrospective cohort study. Objectives To determine the outcome and any differences in the clinical results of three different surgical methods for lumbar disk herniation and to assess the effect of factors that could predict the outcome of surgery. Methods We evaluated 148 patients who had operations for lumbar disk herniation from March 2006 to March 2011 using three different surgical techniques (laminectomy, microscopically assisted percutaneous nucleotomy, and spinous process osteotomy) by using Japanese Orthopaedic Association (JOA) Back Pain Evaluation Questionnaire, Resumption of Activities of Daily Living scale and changes of visual analog scale (VAS) for low back pain and radicular pain. Our study questionnaire addressed patient subjective satisfaction with the operation, residual complaints, and job resumption. Data were analyzed with SPSS version 16.0 (SPSS, Inc., Chicago, Illinois, United States). Statistical significance was set at 0.05. For statistical analysis, chi-square test, Mann-Whitney U test, Kruskal-Wallis test, and repeated measure analysis were performed. For determining the confounding factors, univariate analysis by chi-square test was used and followed by logistic regression analysis. Results Ninety-four percent of our patients were satisfied with the results of their surgeries. VAS documented an overall 93.3% success rate for reduction of radicular pain. Laminectomy resulted in better outcome in terms of JOA Back Pain Evaluation Questionnaire. The outcome of surgery did not significantly differ by age, sex, level of education, preoperative VAS for back, preoperative VAS for radicular pain, return to previous job, or level of herniation. Conclusion Surgery for lumbar disk herniation is effective in reducing radicular pain (93.4%). All three surgical approaches resulted in significant decrease in preoperative radicular pain and low back pain, but intergroup variation in the outcome was not achieved. As indicated by JOA Back Pain Evaluation Questionnaire-Low Back Pain (JOABPQ-LBP) and lumbar function functional scores, laminectomy achieved significantly better outcome compared with other methods. It is worth mentioning that relief of radicular pain was associated with subjective satisfaction with the surgery among our study population. Predictive factors for ineffective surgical treatment for lumbar disk herniation were female sex and negative preoperative straight leg raising. Age, level of education, and preoperative VAS for low back pain were other factors that showed prediction power.

Abstract
Designer self-assembling peptide nanofiber hydrogel scaffolds have been considered as promising biomaterials for tissue engineering because of their excellent biocompatibility and biofunctionality. Our previous studies have shown that a novel designer functionalized self-assembling peptide nanofiber hydrogel scaffold (RLN/RADA16, LN-NS) containing N-terminal peptide sequence of link protein (link N) can promote nucleus pulposus cells (NPCs) adhesion and three-dimensional (3D) migration and stimulate biosynthesis of type II collagen and aggrecan by NPCs in vitro. The present study has extended these investigations to determine the effects of this functionalized LN-NS on bone marrow stem cells (BMSCs), a potential cell source for NP regeneration. Although the functionalized LN-NS cannot promote BMSCs proliferation, it significantly promotes BMSCs adhesion compared with that of the pure RADA16 hydrogel scaffold. Moreover, the functionalized LN-NS remarkably stimulates biosynthesis and deposition of type II collagen and aggrecan. These data demonstrate that the functionalized peptide nanofiber hydrogel scaffold containing link N peptide as a potential matrix substrate will be very useful in the NP tissue regeneration.

Abstract
BACKGROUND Acute disc prolapse in young adults has been studied extensively. However, little is known about acute disc prolapse in the elderly. OBJECTIVE We aimed to define the features of acute disc prolapse in the elderly. DESIGN, SETTING AND PATIENTS Elderly (≥ 65 years) patients who had lumbar or thoracic discectomy for acute (< 3 months) disc prolapse in our unit between July 2004 and March 2010 were identified. For comparison, we used a 'young' (25-45 years) patient cohort with acute thoracic or lumbar disc prolapse. Data collected included age, symptom onset, preoperative signs and spinal level. RESULTS During the study period, 390 patients had discectomy, of which 59.7% were 'young' and 7.4% 'elderly'. The young and elderly patients had significantly different distributions of prolapsed disc levels. In the young, 97% of all disc protrusions were at L4/5 or L5/S1, but < 50% were at these levels in the elderly. In the elderly, about 10% of disc protrusions were thoracic. CONCLUSIONS Acute disc prolapse is rare in the elderly and primarily affects the upper lumbar and lower thoracic spine.

Abstract
OBJECTIVES To determine whether older adults (aged ≥ 60) experience less improvement in disability and pain with nonsurgical treatment of lumbar disk herniation (LDH) than younger adults (< 60). DESIGN Prospective longitudinal comparative cohort study. SETTING Outpatient specialty spine clinic. PARTICIPANTS One hundred thirty-three consecutive patients with radicular pain and magnetic resonance-confirmed acute LDH (89 younger, 44 older). INTERVENTION Nonsurgical treatment customized for the individual patient. MEASUREMENTS Patient-reported disability on the Oswestry Disability Index (ODI), leg pain intensity, and back pain intensity were recorded at baseline and 1, 3, and 6 months. The primary outcome was the ODI change score at 6 months. Secondary longitudinal analyses examined rates of change over the follow-up period. RESULTS Older adults demonstrated improvements in ODI (range 0-100) and pain intensity (range 0-10) with nonsurgical treatment that were not significantly different from those seen in younger adults at 6 month follow-up, with or without adjustment for potential confounders. Adjusted mean improvement in older and younger adults were 31 versus 33 (P = .63) for ODI, 4.5 versus 4.5 (P = .99) for leg pain, and 2.4 versus 2.7 for back pain (P = .69). A greater amount of the total improvement in leg pain and back pain in older adults was noted in the first month of follow-up than in younger adults. CONCLUSION These preliminary findings suggest that the outcomes of LDH with nonsurgical treatment were not worse in older adults (≥ 60) than in younger adults (< 60). Future research is warranted to examine nonsurgical treatment for LDH in older adults.

Abstract
INTRODUÇÃO: a hérnia de disco lombar (HDL) é uma patologia prevalente na atualidade, que acarreta limitações físicas, psiquícas e sociais ao paciente. Os sinais e sintomas mais frequentes são lombociatalgia, distúrbios motores e sensitivos e sinal de Lasègue. Nos pacientes com HDL refrátarios ao tratamento clínico, microdiscectomia é o procedimento padrão para a melhora dos sintomas. OBJETIVOS: estudar a relevância prognóstica dos sinais e sintomas nos pacientes com HDL refratários ao tratamento clínico. MÉTODOS: foram pesquisados, nas principais bases de dados biomédicas, os artigos que estudaram a percentagem de melhora e o valor prognóstico dos sinais e sintomas pré-operatórios dos pacientes com HDL. Os sinais e os sintomas avaliados foram dor lombar, dor na perna, distúrbios motores e sensitivos e sinal de Lasègue. CONCLUSÃO: o índice de sucesso da cirurgia dos pacientes com HDL refratários ao tratamento clínico correlaciona-se com a ausência de lombalgia, a presença de ciatalgia com tempo de evolução de até 6 meses, o déficit sensitivo presente de forma isolada ou associado ao déficit motor e a presença de sinal de Lasègue positivo no período pré-operatório.

BACKGROUND The number of patients suffering from degenerative diseases in the lumbar spine is increasing in Japan. Although various scales to measure disability or quality of life in patients with low back pain and/or lumbar diseases are currently available, it has been shown that one questionnaire is not always compatible with another. Our purpose is to evaluate the association and differences between the Japanese version of the Roland-Morris Disability Questionnaire and the Japanese Orthopaedic Association score for low back pain. METHODS These two scales were examined and compared using data from 602 patients with low back pain and/or lumbar disease. The associations between the Japanese version of the Roland-Morris Disability Questionnaire and each subscale in the Japanese Orthopaedic Association score in back pain dominant group and leg pain dominant group, and with respect to six pathological conditions (i.e., sciatica, spondylosis, spondylolisthesis, lumbar spinal canal stenosis, muscular pain, traumatic pain) were analyzed. RESULTS While the Japanese version of the Roland-Morris Disability Questionnaire and the Subjective and Activities of daily living (ADL) subscale of the Japanese Orthopaedic Association score showed a good correlation (r > 0.60), the Japanese version of the Roland-Morris Disability Questionnaire and the Clinical subscale showed a weak correlation (r = 0.35). Among the six pathological conditions, the correlation between the Japanese version of the Roland-Morris Disability Questionnaire and the Japanese Orthopaedic Association score was the lowest (r = 0.66) in the lumbar spinal canal stenosis category. CONCLUSIONS The clinical signs in patients with low back pain and/or lumbar diseases are not associated closely with the Japanese version of the Roland-Morris Disability Questionnaire. Therefore, a combination of the Japanese version of the Roland-Morris Disability Questionnaire and the Japanese Orthopaedic Association score can provide wide-ranging assessment of the level of impairment in patients with low back pain and/or lumbar diseases.

Abstract
BACKGROUND Lumbar discectomy is among the most frequently performed procedures by spine surgeons. Among the potential difficulties encountered during this procedure, incorrect spinal level surgery remains a significant concern for surgeons and patients. Multiple groups have advocated the use of intraoperative x-ray to reduce the incidence of incorrect level surgery; however, this technique has not been prospectively evaluated. METHODS In an effort to determine the incidence of incorrect level exposure during lumbar discectomy and to define patient characteristics predictive of wrong level exposure, we examined 100 consecutive patients who underwent lumbar discectomy by a single surgeon. After exposure, the surgeon was asked to identify the level exposed, which was confirmed by intraoperative x-ray. Several patient characteristics were then examined by logistical regression to identify features predictive of a mismatch between level of exposure and level of pathology. RESULTS The study population was composed of 48 men and 52 women who were aged 18 to 83 years. Patient weights ranged from 105 to 410 lb. There were 51 patients who had pathology at the L5-S1 level; 44 patients, L4-L5; 3 patients, L3-L4; and 1 patient, L2-L3. Four patients had transitional vertebrae. The intended level was initially exposed in 85% of cases. Age and level of pathology (P < .05) were identified as factors predictive of a mismatch between intraoperative level of exposure and preoperative level of pathology. CONCLUSIONS Pathology above L5-S1 and patient age have been shown to reliably predict incorrect level exposure. Based upon the findings of this study, the routine use of intraoperative x-ray to confirm the level of exposure should be considered in all cases of lumbar discectomy.
