Abstract
BACKGROUND Cost, efficiency, patient preference, and safety have driven utilization of wide awake, local anesthesia, no tourniquet (WALANT) in hand surgery. This is not well documented in adolescents. We hypothesize that the use of WALANT with adolescents reduced time spent in the operating room (OR) and in the hospital when compared with patients who underwent surgery with traditional anesthesia (TA). METHODS After institutional review board approval, we performed a retrospective review of patients aged 10 to 17 who underwent surgery at a regional hospital system including the level 1 pediatric trauma hospital. Operative notes were assessed for use of WALANT. We excluded those operations not traditionally amenable to WALANT. Using a propensity matched cohort, hospital time, OR time, and perioperative complications were recorded and compared to evaluate efficiency and perioperative safety. RESULTS There were 28 cases in the WALANT group and 28 cases in the TA group after excluding cases not amenable to WALANT, and cases were propensity matched. Although the operative time (incision to closure) was similar, for WALANT patients, the in-room to procedure time (15 vs 22 minutes), procedure end to out-room time (5 vs 10 minutes), total room time (52.81 vs 63.68), and length of hospital stay (222 vs 342 minutes) were shorter than patients in the TA group. CONCLUSION Our case series demonstrates time-savings both in the OR and in the hospital overall. Avoiding TA when WALANT is feasible may result in significant savings to hospital systems, patients, and payers while also freeing up anesthesia staff and perioperative nurses.

Abstract
STUDY DESIGN Retrospective quality improvement study. OBJECTIVE To investigate if the rate of unsuspected malignancy in biopsies in patients with VCF who underwent PVP at the same orthopedic department has changed after implementation of a new MRI scanning protocol. SUMMARY OF BACKGROUND DATA Discrimination between benign and malign vertebral compression fracture (VCF) can be difficult. However, early diagnosis of malignant VCF is crucial to further treatment and prognosis. An earlier study at an orthopedic department reported a rate of unsuspected malignancy of 4.9% in patients with VCF who underwent percutaneous vertebroplasty (PVP) when biopsies were obtained during the procedure. MRI scanning protocol was changed in this period. METHODS Retrospective on 427 patients with vertebral compression fracture undergoing PVP from 28th of April 2017 to 28th of April 2022, identifying operated patients from the Danish national DaneSpine registry. Subsequently, individual clinical information was collected in journal records. RESULTS The rate of unsuspected malignancy was 0.9% (4/427) and the overestimation of malignant VCF was 50% (16/32). CONCLUSION During the last 5 years, the rate of unsuspected malignancy in patients with VCF undergoing PVP has improved considerably from 4.9% to 0.9%. Furthermore, MRI is over-diagnosing malignancies. Thus, the new scanning procedure is effective in differentiating between benign and malign VCFs. LEVEL OF EVIDENCE 3.

Abstract
STUDY DESIGN Systematic Review. OBJECTIVE To evaluate the efficacy of available treatment options for patients with persistent coccydynia through a systematic review. METHODS Original peer-reviewed publications on treatment for coccydynia were identified using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines by performing a literature search of relevant databases, from their inception to January 17, 2020, combined with other sources. Data on extracted treatment outcome was pooled based on treatment categories to allow for meta-analysis. All outcomes relevant to the treatment efficacy of coccydynia were extracted. No single measure of outcome was consistently present among the included studies. Numeric Rating Scale, (NRS, 0-10) for pain was used as the primary outcome measure. Studies with treatment outcome on adult patients with chronic primary coccydynia were considered eligible. RESULTS A total of 1980 patients across 64 studies were identified: five randomized controlled trials, one experimental study, one quasi-experimental study, 11 prospective observational studies, 45 retrospective studies and unpublished data from the DaneSpine registry. The greatest improvement in pain was achieved by patients who underwent radiofrequency therapy (RFT, mean Visual Analog Scale (VAS) decreased by 5.11 cm). A similar mean improvement was achieved from Extracorporeal Shockwave Therapy (ESWT, 5.06), Coccygectomy (4.86) and Injection (4.22). Although improved, the mean change was less for those who received Ganglion block (2.98), Stretching/Manipulation (2.19) and Conservative/Usual Care (1.69). CONCLUSION This study highlights the progressive nature of treatment for coccydynia, starting with noninvasive methods before considering coccygectomy. Non-surgical management provides pain relief for many patients. Coccygectomy is by far the most thoroughly investigated treatment option and may be beneficial for refractory cases. Future randomized controlled trials should be conducted with an aim to compare the efficacy of interventional therapies amongst each other and to coccygectomy.

Abstract
INTRODUCTION Surgical instrumentation in children with adolescent idiopathic scoliosis (AIS) is performed early in life and the implants are left in situ for the rest of the patient's life. Concern has been raised regarding persistent elevated levels of serum metal ions, but only a few studies on the topic have been published. The aim of this study was to compare the levels of serum metal ions in patients with AIS treated with either Harrington rod instrumentation or bracing. MATERIALS AND METHODS AIS patients treated with Boston brace (BB) or posterior spinal fusion with Harrington rod instrumentation (HR) from 1983 to 1990 were requested to return to clinic. One hundred fifty-nine (73%) of 219 patients were available for follow-up of whom 115 agreed to have a blood draw. RESULTS The proportion of patients who agreed to have a blood draw were similar in the BB (48 of 100, 48%) and HR (67 of 115, 60%, p = 0.085) groups. None of the surgical patients had their implants removed; mean age at follow-up (BB: 43.2 years vs HR: 43.5 years, p = 0.566) and mean length of follow-up (BB: 26.5 years vs HR: 24.5 years). Mean chromium serum levels were similar between the BB (2.7 nmol/L) and the HR (2.9 nmol/L, p = 0.827). Mean Cobalt serum levels were also similar between the BB (2.6 nmol/L) and the HR (2.8 nmol/L, p = 0.200). CONCLUSION Serum metal ions were similar in AIS patients treated with bracing or Harrington rod instrumentation 25 years after initiation of treatment.

Abstract
BACKGROUND Obesity rates continue to rise among children and adolescents across the globe. A multicenter research consortium composed of institutions in the Southern US, located in states endemic for childhood obesity, was formed to evaluate the effect of obesity on pediatric musculoskeletal disorders. This study evaluates the effect of body mass index (BMI) percentile and socioeconomic status (SES) on surgical site infections (SSIs) and perioperative complications in patients with adolescent idiopathic scoliosis (AIS) treated with posterior spinal fusion (PSF). METHODS Eleven centers in the Southern US retrospectively reviewed postoperative AIS patients after PSF between 2011 and 2017. Each center contributed data to a centralized database from patients in the following BMI-for-age groups: normal weight (NW, 5th to <85th percentile), overweight (OW, 85th to <95th percentile), and obese (OB, ≥95th percentile). The primary outcome variable was the occurrence of an SSI. SES was measured by the Area Deprivation Index (ADI), with higher scores indicating a lower SES. RESULTS Seven hundred fifty-one patients were included in this study (256 NW, 235 OW, and 260 OB). OB and OW patients presented with significantly higher ADIs indicating a lower SES (P<0.001). In addition, SSI rates were significantly different between BMI groups (0.8% NW, 4.3% OW, and 5.4% OB, P=0.012). Further analysis showed that superficial and not deep SSIs were significantly different between BMI groups. These differences in SSI rates persisted even while controlling for ADI. Wound dehiscence and readmission rates were significantly different between groups (P=0.004 and 0.03, respectively), with OB patients demonstrating the highest rates. EBL and cell saver return were significantly higher in overweight patients (P=0.007 and 0.002, respectively). CONCLUSION OB and OW AIS patients have significantly greater superficial SSI rates than NW patients, even after controlling for SES. LEVEL OF EVIDENCE Level III.

Abstract
Background In 2011, studies suggested that complications and cancer rates associated with bone morphogenetic protein (BMP) were greater than previously reported. However, later studies reported complication rates similar to prior literature and no increased cancer rate. We evaluated the pattern of clinical utilization of BMP in posteriorly based lumbar fusion by comparing two periods: 2002-2004 and 2017-2019. Methods Patients who received BMP from 2002-2004 (Early) and 2017-2019 (Late) from a single multi-surgeon institution who had a lumbar fusion were identified. One hundred patients from each cohort were randomly selected. Mean total BMP used at each level and the proportion of BMP placed in the interbody space versus posterolateral gutters were evaluated. Results In the transforaminal lumbar intebody fusion (TLIF) cohort, the total BMP dose in the Late group (6.15 mg) was nearly half of that used in the Early group (12.04 mg, p<0.000). The amount of BMP used in the posterolateral gutters remained similar (Early: 4.01 mg vs Late: 3.38 mg, p=0.222). The amount of BMP used in the interbody space was less in the Late group (2.76 mg) compared to the Early group (8.03 mg, p<0.000). In the posterior spinal fusion (PSF) cohort, the total BMP dose remained similar between the Early (11.96 mg) and the Late groups (10.82 mg, p=0.007). Conclusion Change in the use of BMP in TLIF cases was driven by the complications reported in the literature with no change in outcome. A similar impetus was not seen for PSF.

Abstract
INTRODUCTION Multiple myeloma (MM) is a plasma cell cancer where about 1/3 of the patients present with pathological fractures at the time of diagnosis. Despite treatment, the majority of the patients will develop additional fractures. Because survival and prognosis has improved significantly over the last two decades for patients with MM, there is an increased need to focus on optimal fracture treatment. Traditionally, fracture pain is treated conservatively with opioids, bisphosphonates, bracing and radiation therapy. Vertebral augmentation has been used for the last three decades as a minimally invasive treatment option for vertebral compression fractures, but the evidence base for the efficacy is weak. We describe a trial assessing the impact of vertebroplasty on clinical outcome in the treatment of patients with MM with painful vertebral fractures. METHODS 100 patients with MM with painful vertebral fractures will be randomised in a prospective, single-blinded, multicentre, clinical trial where patients are randomised to either usual care or usual care supplemented with vertebroplasty with a possibility of crossover 4 weeks after randomisation. The primary outcome will be change in Oswestry Disability Index at 4 weeks. ANALYSIS Primary and secondary outcomes are assessed at baseline and at 4, 8, 26 and 52 weeks. Categorical data will be presented by means of frequencies and related percentages; continuous data will be displayed by means of descriptive statistics. ETHICS AND DISSEMINATION The study has been evaluated by the Regional Committees on Health Research for Southern Denmark (S-20200075) and notified and approved by the Region of Southern Denmark and listed in the internal record, journal no. 20/22355. All participants provide consent. The protocol will follow the SPIRIT (Standard Protocol Items for Randomized Trials) statement. The Danish Myeloma Patient Organization supports the study. Findings will be disseminated in peer-reviewed publications and presented at national and international conferences. TRIAL REGISTRATION NUMBER NCT04533217.

Abstract
Aims The aim of this study was to identify factors associated with poor outcome following coccygectomy on patients with chronic coccydynia and instability of the coccyx. Methods From the Danish National Spine Registry, DaneSpine, 134 consecutive patients were identified from a single centre who had coccygectomy from 2011 to 2019. Patient demographic data and patient-reported outcomes, including pain measured on a visual analogue scale (VAS), Oswestry Disability Index (ODI), EuroQol five-dimension five-level questionnaire, and 36-Item Short-Form Health Survey questionnaire (SF-36) were obtained at baseline and at one-year follow-up. Patient satisfaction was obtained at follow-up. Regression analysis, including age, sex, smoking status, BMI, duration of symptoms, work status, welfare payment, preoperative VAS, ODI, and SF-36 was performed to identify factors associated with dissatisfaction with results at one-year follow-up. Results A minimum of one year follow-up was available in 112 patients (84%). Mean age was 41.9 years (15 to 78) and 97 of the patients were female (87%). Regression showed no statistically significant association between the investigated prognostic factors and a poor outcome following coccygectomy. The satisfied group showed a statistically significant improvement in patient-reported outcomes at one-year follow-up from baseline, whereas the dissatisfied group did not show a significant improvement. Conclusion We did not identify factors associated with poor outcome following coccygectomy. This suggests that neither of the included parameters should be considered contraindications for coccygectomy in patients with chronic coccydynia and instability of the coccyx.

Abstract
STUDY DESIGN International, multicenter, prospective, longitudinal observational cohort. OBJECTIVE To assess how new motor deficits affect patient reported quality of life scores after adult deformity surgery. SUMMARY OF BACKGROUND DATA Adult spinal deformity surgery is associated with high morbidity, including risk of new postoperative motor deficit. It is unclear what effect new motor deficit has on Health-related Quality of Life scores (HRQOL) scores. METHODS Adult spinal deformity patients were enrolled prospectively at 15 sites worldwide. Other inclusion criteria included major Cobb more than 80°, C7-L2 curve apex, and any patient undergoing three column osteotomy. American Spinal Injury Association (ASIA) scores and standard HRQOL scores were recorded pre-op, 6 weeks, 6 months, and 2 years. RESULTS Two hundred seventy two complex adult spinal deformity (ASD) patients enrolled. HRQOL scores were worse for patients with lower extremity motor score (LEMS). Mean HRQOL changes at 6 weeks and 2 years compared with pre-op for patients with motor worsening were: ODI (+12.4 at 6 weeks and -4.7 at 2 years), SF-36v2 physical (-4.5 at 6 weeks and +2.3 at 2 years), SRS-22r (0.0 at 6 weeks and +0.4 at 2 years). Mean HRQOL changes for motor-neutral patients were: ODI (+0.6 at 6 weeks and -12.1 at 2 years), SF-36v2 physical (-1.6 at 6 weeks and +5.9 at 2 years), and SRS-22r (+0.4 at 6 weeks and +0.7 at 2 years). For patients with LEMS improvement, mean HRQOL changes were: ODI (-0.6 at 6 weeks and -16.3 at 2 years), SF-36v2 physical (+1.0 at 6 weeks and +7.0 at 2 years), and SRS-22r (+0.5 at 6 weeks and +0.9 at 2 years). CONCLUSION In the subgroup of deformity patients who developed a new motor deficit, total HRQOLs and HRQOL changes were negatively impacted. Patients with more than 2 points of LEMS worsening had the worst changes, but still showed overall HRQOL improvement at 6 months and 2 years compared with pre-op baseline.Level of Evidence: 3.

Abstract
AIMS The aim of this study was to investigate the efficacy of coccygectomy in patients with persistent coccydynia and coccygeal instability. METHODS The Danish National Spine Registry, DaneSpine, was used to identify 134 consecutive patients who underwent surgery, performed by a single surgeon between 2011 and 2019. Routine demographic data, surgical variables, and patient-reported outcomes, including a visual analogue scale (VAS) (0 to 100) for pain, Oswestry Disability Index (ODI), EuroQol five-dimension questionnaire (EQ-5D), and the Physical Component Score (PCS) and Mental Component Score (MCS) of the 36-Item Short-Form Health Survey questionnaire (SF-36) were collected at baseline and one-year postoperatively. RESULTS A total of 112 (84%) patients with a minimum follow-up of one year had data available for analysis. Their mean age was 41.9 years, and 15 (13%) were males. At 12 months postoperatively, there were statistically significant improvements (p < 0.001) from baseline for the mean VAS for pain (70.99 to 35.34), EQ-5D (0.52 to 0.75), ODI (31.84 to 18.00), and SF-36 PCS (38.17 to 44.74). A total of 78 patients (70%) were satisfied with the outcome of treatment. CONCLUSION Patients with persistent coccydynia and coccygeal instability resistant to nonoperative treatment may benefit from coccygectomy. Cite this article: Bone Joint J 2021;103-B(3):542-546.

Abstract
STUDY DESIGN Longitudinal cohort study. OBJECTIVES To investigate whether a cutoff point in leg pain intensity measured preoperatively or at early follow-up could identify patients at risk of poor outcomes in terms of disability at 1-year and 2-year follow-up after first-time lumbar discectomy, and to identify the characteristics associated with early postoperative leg pain intensity. METHODS From 2010 to 2013, 556 patients underwent lumbar discectomy. Leg pain intensity was measured preoperatively and at early postoperative follow-up and dichotomized according to an established cutoff point on a 0 to 100 visual analogue scale (mild <30, moderate/severe ≥30). The outcome measurement was Oswestry Disability Index (ODI). Generalized estimating equations modelling established the association between leg pain intensity and ODI. Characteristics associated with early postoperative leg pain intensity were identified using common hypothesis tests. RESULTS Moderate/severe leg pain intensity at early follow-up showed a statistically significant association with higher ODI at 1-year and 2-year follow-up compared to mild leg pain intensity (median [interquartile range]: 24 [26] and 26 [26] versus 12 [18] and 10 [20], respectively). Patients reporting moderate/severe leg pain intensity were more often smokers, were more prone to receive social benefits, and were more prone to have chronic back pain. The preoperative measurement of leg pain intensity showed inferior associations. CONCLUSION The proposed cutoff point in leg pain intensity at early follow-up can identify patients at risk of disability at both 1-year and 2-year follow-up after first-time discectomy. Future research should be undertaken to investigate whether patients with moderate/severe leg pain intensity at early postoperative follow-up could benefit from additional or more intensive postoperative interventions.

Abstract
OBJECTIVEPatients with lumbar disc herniation (LDH) typically present with lower-extremity radiculopathy. However, there are patients who have concomitant substantial back pain (BP) and are considered candidates for fusion. The purpose of this study was to determine if patients with LDH and substantial BP improve with discectomy alone.METHODSThe DaneSpine database was used to identify 2399 patients with LDH and baseline BP visual analog scale (VAS) scores ≥ 50 who underwent a lumbar discectomy at one of 3 facilities between June 2010 and December 2017. Standard demographic and surgical variables and patient-reported outcomes, including BP and leg pain (LP) VAS scores (0–100), Oswestry Disability Index (ODI), and European Quality of Life–5 Dimensions Questionnaire (EQ-5D) at baseline and 12 months postoperatively, were collected.RESULTSA total of 1654 patients (69%) had 12-month data available, with a mean age of 48.7 years; 816 (49%) were male and the mean BMI was 27 kg/m2. At 12 months postoperatively, there were statistically significant improvements (p < 0.0001) in BP (72.6 to 36.9), LP (74.8 to 32.6), ODI (50.9 to 25.1), and EQ-5D (0.25 to 0.65) scores.CONCLUSIONSPatients with LDH and LP and concomitant substantial BP can be counseled to expect improvement in their BP 12 months after surgery after a discectomy alone, as well as improvement in their LP.

Abstract
Purpose Continued inability to work has societal and individual consequences. Thus, the factors associated with sustained return to work after lumbar discectomy should be identified. Prior studies of the biopsychosocial factors associated with sustained RTW were primarily based on patient-reported outcome data and have shown conflicting results because of small study samples. In patients undergoing first-time, single-level, simple lumbar discectomy, we describe the time to sustained return to work within 2 years after surgery using outcome data from a national database and identify the pre- and peri-operative factors associated with sustained return to work within 2 years by developing and validating a predictive multivariable model. Methods The time to a sustained return to work within the study period was described using a Kaplan-Meier plot. A temporal validated Cox proportional hazards model examined associations between biopsychosocial factors and return to work. Results In the derivation cohort made up by 351 operated patients who were on sick-leave for more than 3 weeks around the time of surgery, 62% returned to work (median 15 weeks). The probability of sustained return to work was associated with a high education level, positive expectations towards future labor market attachment, pre-operative stable labor market attachment, pre-operative higher physical quality of life, and less disability. Conclusions Through the development and validation of a predictive model, this study identifies a number of patient-related factors associated with sustained return to work after lumbar discectomy, while revealing that most disease-related clinical findings were not associated with the outcome.

Abstract
A survey was administered to a random sampling of the American Academy of Orthopaedic Surgeons (AAOS) members to determine the rate at which recently trained orthopedic surgeons switch their first job and to identify factors affecting the job selection process. There were 351 (21%) respondents. Respondents considered practice location (41%), practice type (28%), and family proximity (23%) as most important while research opportunity (54%) and signing bonus (33%) were considered least important in their first job. Half of the respondents (51%) left their first job before the completion of their fifth year; most left for financial reasons (34%) or because the practice was not as advertised (31%). Many (53%) stated they had minimal training in selecting their first job and most (88%) felt inadequately prepared for the business side of orthopedics. Further studies are needed to evaluate the high rate of initial post-training job attrition to decrease the personal and societal costs of this phenomenon.

Abstract
BACKGROUND CONTEXT Percutaneous vertebroplasty (PVP) and kyphoplasty (KP) are minimally invasive treatment options for vertebral compression fractures (VCFs) due to malignancy. PURPOSE To perform a systematic review evaluating the effectiveness and safety of vertebral augmentation for malignant VCFs. STUDY DESIGN Systematic review. STUDY SAMPLE Studies on PVP or KP for VCFs in patients with malignant spinal lesions. OUTCOME MEASURES Visual Analog Scale (VAS) for pain, Oswestry Disability Index (ODI), Karnofsky Performance Score (KPS), and complications were extracted from eligible studies. METHODS Using Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, studies published between January 1, 2000 and January 3, 2018 were identified by combining the results of a report by Health Quality Ontario with an updated literature search. RESULTS The review identified two randomized controlled trials, 16 prospective studies, 44 retrospective studies, and 25 case series for a patient sample size of 3,426. At the earliest follow-up, pain improved from 7.48 to 3.00 with PVP, and from 7.05 to 2.96 with KP. ODI improved from 74.68 to 17.73 with PVP, and from 66.02 to 34.73 with KP. KPS improved from 66.99 to 80.28. Cement leakage was seen in 37.9% and 13.6% of patients treated with PVP and KP, respectively. Symptomatic complications (N = 43) were rare. CONCLUSIONS This review showed clinically relevant improvements in pain, ODI, and KPS in patients with VCFs due to malignancy treated with either PVP or KP. Cement leakage is common, but rarely symptomatic. Percutaneous vertebroplasty and KP are safe and effective palliative procedures for painful VCFs in patients with malignant spinal lesions.

Abstract
INTRODUCTION Radio-frequency (RF) denervation of the facet joints is a procedure aimed at the nociceptive median branch nerves of the lumbar dorsal rami. Pain signals from the facet joints are carried through these fibres; by ablating these fibres, central signalling can be prevented. This pilot study investigated the clinical effect and feasibility of the procedure at our institution, the Spine Centre of Southern Denmark. METHODS Patients with at least 50% pain relief after initial medial branch diagnostic blocks were candidates for RF denervation. Patients were divided into two groups: 1) patients with at least 80% pain relief and 2) patients with between 50% and 79% pain relief after diagnostic blocks. Denervation was performed bilaterally on the three lowest facet joints in the lumbar spine. The primary outcome parameter was visual analogue scale (VAS). Follow-up questionnaires were answered after one week and after three, six and 12 months. RESULTS For the whole sample, we found a mean reduction of 43 VAS points after one week. At three months, we found a mean reduction of 25 points. Six-month data showed a mean 19-point reduction. Twelve-month data showed a mean reduction of 17 points. Group 1 showed superior improvements at all follow-up points and after 12 months, we found a mean VAS reduction of 22 points for this group. CONCLUSIONS This pilot cohort study found RF denervation of the facet joint to be a promising alternative for patients with chronic low-back pain. The effect persisted at the one-year follow-up; however, the effect diminished over time. FUNDING The Danish Rheumatism Association, The A.P. Møller Foundation for the Advancement of Medical Science.

Abstract
BACKGROUND CONTEXT Significant variability in neurologic outcomes after surgical correction for adult spinal deformity (ASD) has been reported. Risk factors for decline in neurologic motor outcomes are poorly understood. PURPOSE The objective of the present investigation was to identify the risk factors for postoperative neurologic motor decline in patients undergoing complex ASD surgery. STUDY DESIGN/SETTING This is a prospective international multicenter cohort study. PATIENT SAMPLE From September 2011 to October 2012, 272 patients undergoing complex ASD surgery were prospectively enrolled in a multicenter, international cohort study in 15 sites. OUTCOME MEASURES Neurologic decline was defined as any postoperative deterioration in American Spinal Injury Association lower extremity motor score (LEMS) compared with preoperative status. METHODS To identify risk factors, 10 candidate variables were selected for univariable analysis from the dataset based on clinical relevance, and a multivariable logistic regression analysis was used with backward stepwise selection. RESULTS Complete datasets on 265 patients were available for analysis and 61 (23%) patients showed a decline in LEMS at discharge. Univariable analysis showed that the key factors associated with postoperative neurologic deterioration included older age, lumbar-level osteotomy, three-column osteotomy, and larger blood loss. Multivariable analysis revealed that older age (odds ratio [OR]=1.5 per 10 years, 95% confidence interval [CI] 1.1-2.1, p=.005), larger coronal deformity angular ratio [DAR] (OR=1.1 per 1 unit, 95% CI 1.0-1.2, p=.037), and lumbar osteotomy (OR=3.3, 95% CI 1.2-9.2, p=.022) were the three major predictors of neurologic decline. CONCLUSIONS Twenty-three percent of patients undergoing complex ASD surgery experienced a postoperative neurologic decline. Age, coronal DAR, and lumbar osteotomy were identified as the key contributing factors.

Abstract
INTRODUCTION In cancer patients with painful vertebral fractures due to spinal metastasis, traditional pain-relieving therapies include analgesics, bed rest, steroids, radio-ther-apy, etc. These treatment modalities are often ineffective. Traditional spinal surgery in general anaesthesia is usually not an option in patients with advanced cancer and in a poor general condition. Percutaneous vertebroplasty (PVP) has been reported as a minimally invasive treatment option with apparent rapid pain relief compared with other conventional treatment options. The objective of this study was to assess the safety and efficacy of PVP in patients with malignant spinal lesions. METHODS From the National Danish Surgical Spine Database, DaneSpine, 30 consecutive cancer patients with vertebral fractures who underwent PVP from 2013 to 2017 were identified. From DaneSpine, the European Quality of Life - 5 Dimensions Questionnaire (EQ-5D) and the Oswestry Disability Index (ODI) scores were collected pre- and post-operatively. Data on the incidence of complications and poly-methyl methacrylate leaks were obtained by review of medical records and plain post-operative X-rays. RESULTS The mean improvement in EQ-5D scores from baseline was 0.30 (p < 0.01) after three months, and 0.25 (p = 0.01) after one year. The ODI improved from 44.1 to 23.3 (p < 0.01). Despite a cement leakage rate of 14.8%, no patients presented with any clinically significant symptoms. CONCLUSIONS PVP is a safe procedure providing a statistically significant and clinically relevant improvement in quality of life and function of patients with cancer-related vertebral compression fractures. Our findings may provide useful information to healthcare professionals who are treating cancer. FUNDING none. TRIAL REGISTRATION not relevant.

Abstract
BACKGROUND CONTEXT Adult spinal deformity (ASD) surgery is associated with significant resource utilization, costing more than $958 million in charges for Medicare patients and more than $1.7 billion in charges for managed care population in the last decade. Given the recent move toward bundled payment models, it is important to understand the various care components a patient receives over the course of a defined clinical episode, its associated cost, and the proportion of cost for each component toward the bundled payment. PURPOSE To examine the degree and determinants of variation in inpatient episode-of-care (EOC) cost, resource utilization, and patient-reported outcomes for patients undergoing ASD surgery across four spine deformity centers in the United States. STUDY DESIGN/SETTING Retrospective analysis of prospective, multicenter database. PATIENT SAMPLE Consecutive patients enrolled in an ASD database from four spinal deformity centers. OUTCOME MEASURES Total in-patient EOC costs and Short Form (SF)-6D. METHODS The study used a multicenter database of 210 consecutively enrolled operative patients from 2008 to 2013 at four participating centers in the United States. Demographic, surgical, and direct cost data, expressed in 2013 dollars, for the entire inpatient EOC were obtained from administrative databases from the respective hospitals. Mixed models and multivariable linear regression were used to evaluate the impact of center on total costs adjusting for patient characteristics, length of stay (LOS), and surgical factors. RESULTS A total of 126 patients with complete baseline and 2-year follow-up data were included. The percentages of patients from each center were 36.5%, 7.1%, 24.6%, and 31.7%. Overall, the mean patient age was 58.4±12.6 years, 86% were women, and 94% were Caucasian. The proportion of total cost variation explained by the center at which the patient was treated was 17%. After adjusting for patient, LOS, and surgical factors the cost variation reduced to 4%. In multivariable analysis, each additional level fused increased total cost variation by $2,500, whereas recombinant human bone morphogenetic protein-2 (BMP) use and posterior-only surgical approach lowered total EOC costs by $10,500 and $9,400, respectively. No significant difference was observed in 2-year quality-adjusted life year across centers. CONCLUSIONS Total EOC costs for ASD surgery varied significantly by center. Levels fused, BMP use, and surgical approach were the primary drivers of cost variation across centers. Differences in resource utilization had no impact on 2-year quality-adjusted life year improvement across centers.

Abstract
Abstract
BACKGROUND
Surgical treatment for lumbar spinal stenosis is associated with both short- and long-term benefits with improvements in patient function and pain. Even though most patients are satisfied postoperatively, some studies report that up to one-third of patients are dissatisfied.
OBJECTIVE
To present clinical outcome data and identify prognostic factors related to patient satisfaction 1 yr after posterior decompression surgery for lumbar spinal stenosis.
METHODS
This multicenter register study included 2562 patients. Patients were treated with various types of posterior decompression. Patients with previous spine surgery or concomitant fusion were excluded. Patient satisfaction was analyzed for associations with age, sex, body mass index, smoking status, duration of pain, number of decompressed vertebral levels, comorbidities, and patient-reported outcome measures, which were used to quantify the effect of the surgical intervention.
RESULTS
At 1-yr follow-up, 62.4% of patients were satisfied but 15.1% reported dissatisfaction. The satisfied patients showed significantly greater improvement in all outcome measures compared to the dissatisfied patients. The outcome scores for the dissatisfied patients were relatively unchanged or worse compared to baseline. Association was seen between dissatisfaction, duration of leg pain, smoking status, and patient comorbidities. Patients with good walking capacity at baseline were less prone to be dissatisfied compared to patients with poor walking capacity.
CONCLUSION
This study found smoking, long duration of leg pain, and cancerous and neurological disease to be associated with patient dissatisfaction, whereas good walking capacity at baseline was positively associated with satisfaction after 1 yr.

Abstract
PURPOSE The purpose of this study is to determine if there are any demographic and reporting differences between patients who respond and those who refuse to respond to postal questionnaires from the Danish national spine database, DaneSpine. METHODS DaneSpine collects patient-reported data, completed before surgery and at 3 months, and at 1, 2, 5, and 10 years postoperatively. The database was launched at the Center for Spine Surgery and Research at Lillebaelt Hospital on June 1st, 2010. We performed a 1-year follow-up on non-responders during a 6-month period between the 1st of August 2013 until the 31st of January 2014 using a structured phone interview to collect patient-reported outcomes, some health information and reasons for non-response. RESULTS Of the 506 patients who were 1-year post-operative, three did not have baseline data and six had died before the 1-year follow-up. Twenty-four patients had a second spine surgery and were re-enrolled in the database. These cases had not reached the 1-year follow-up period for the second spine surgery and were excluded from the analysis. Thus, 473 patients had reached 1-year follow-up. Of these, 57 (12 %) did not respond to postal questionnaires. A structured phone interview was performed on these 57 non-responders. Non-responders were in general, a decade younger than responders, a greater proportion were males and smokers. Apart from EQ-5D, there was no difference in patient satisfaction, improvement in back pain or leg pain between the responders and non-responders. CONCLUSIONS Missing data from 12 % of patients do not seem to bias conclusions that can be drawn from the DaneSpine database at the Center for Spine Surgery and Research at Lillebaelt Hospital.

Abstract
INTRODUCTION Following the municipal reform in Denmark in January 2007, the municipalities gained responsibility for post-operative rehabilitation. In the Region of Southern Denmark, this task was decentralised to 22 municipalities, which implied a possible risk for considerable variation. This study examined rehabilitation in the 22 municipalities of the Region of Southern Denmark for patients with lumbar disk herniation. METHODS A total of 22 physiotherapists answered a questionnaire regarding their rehabilitation programmes. The municipalities of 789 patients who had undergone decompressive surgery for lumbar disc herniation were identified. Changes in Oswestry disability index (ODI), EuroQol-5D (EQ-5D) and duration of sick leave were compared among the municipalities. RESULTS Patient-reported outcome measures showed no statistical difference in ODI, EQ-5D or sick leave at the one-year follow-up across the 22 municipalities. There was a correlation between sick leave and outcome as a longer sick leave was associated with less improvement in EQ-5D and ODI. Rehabilitation programmes across the region were comparable with respect to several factors. The questionnaire revealed a potential for enhanced cooperation between hospitals and rehabilitation centres. CONCLUSION Rehabilitation was broadly similar, and patient outcome after one year did not differ significantly across the 22 municipalities or between the five largest samples. In general, all municipalities request enhanced cooperation between hospital and rehabilitation unit to ensure the best possible patient treatment. Further studies should focus on the effect of rehabilitation. FUNDING not relevant. TRIAL REGISTRATION not relevant.

Abstract
Spondylolysis is a source of back pain in adolescents and young adults. The purpose of this study was to report clinical outcomes in 49 patients treated with isolated motion-sparing repair of the pars interarticularis. Patients who underwent direct repair of the pars interarticularis between 2002 and 2009 were identified. Standard demographic and radiographic data, needed for further surgeries, and radiographic evidence of healing were collected. Of 49 patients with 90 total pars defects (41 bilateral, 8 unilateral), 7 required reoperation. No serious complications were seen. None of the risk factors analyzed in our study were predictive of reoperation. The strongest preoperative predictor of Oswestry Disability Index score was Fujii chronicity (P = .041). Motion segment sparing repair of the pars is a safe and effective procedure for refractory cases of spondylolysis.

Abstract
OBJECT This retrospective analysis of Medicare administrative data was performed to evaluate the risk of infection following instrumented lumbar fusion over a 10-year follow-up period in the Medicare population. Although infection can be a devastating complication, due to its rarity it is difficult to characterize infection risk except in large patient populations. METHODS Using ICD-9-CM and CPT4 procedure codes, the Medicare 5% analytical research files for inpatient, outpatient, and physician carrier claims were checked to identify patients who were treated between 1997 and 2009 with lumbar spine fusion in which cages or posterior instrumentation were used. Patients younger than 65 years old were excluded. Patients were followed continuously by using the matching denominator file until they withdrew from Medicare or died. The authors identified 15,069 patients with primary fusion procedures and 605 with revision of instrumented lumbar fusion. Infections were identified by the related ICD-9 codes (998.59 or 996.67) after fusion. Kaplan-Meier survival analysis and Cox regression were performed to determine adjusted infection risk for each type of spine procedure (primary vs revision) and surgical approach (anterior, posterior, combined anteroposterior), accounting for patient (for example, age, sex, comorbidities/Charlson Comorbidity Index [CCI], and state buy-in) and hospital (census region) characteristics. RESULTS At 10 years, the overall infection incidence, including superficial and deep infections, was 8.5% in primary procedures and 12.2% in revisions. Among the factors considered, infection risk within 10 years was most influenced by comorbidities: for a CCI of 5 versus 0, the adjusted hazard ratio (AHR) was 2.48 (95% CI 1.93-3.19, p < 0.001); for ≥ 9 versus 2-3 fused vertebrae, the AHR was 2.39 (95% CI 1.20-4.76, p < 0.001); for revision versus primary fusion procedures, the AHR was 1.66 (95% CI 1.28-2.15, p < 0.001). Other significant predictors of 10-year infection risk included diagnosis of obesity (p < 0.001); state buy-in--a proxy for socioeconomic status (p = 0.02); age (p = 0.003); surgical approach (p = 0.03); census region (p = 0.02); and the year of the index procedure (p = 0.03). CONCLUSIONS Patient comorbidities were the greatest predictor of infection risk for the Medicare population. The high incidence of infection following instrumented fusion warrants increased focus on infection risk mitigation, especially for patients with comorbid conditions.

Abstract
STUDY DESIGN Retrospective case series. OBJECTIVE The purpose of this study was to report on a large consecutive series of posterolateral fusion cases using rhBMP-2/ACS. SUMMARY OF BACKGROUND DATA Despite evidence that rhBMP-2/ACS is effective as an iliac crest graft substitute in posterolateral fusion, concerns remain regarding potential risk for BMP use in clinical practice. These concerns have been fueled by the serious complications reported with BMP in anterior cervical spine fusion. While none of the literature on posterolateral fusion with rhBMP-2/ACS has suggested an increased complication rate versus iliac crest bone graft, this issue has not been specifically studied. METHODS We reviewed medical records for a consecutive series of 1037 patients who underwent posterolateral spine fusion using rhBMP-2 between 2003 and 2006. Medical complications were attributed to the surgical procedure if they occurred within the 3-month perioperative period, whereas complications potentially related to BMP were included regardless of time frame. RESULTS Medical and surgical complications were observed in 190 of 1037 patients (18.3%) with 81 major complications (7.8%) and 110 minor complications (10.2%). Neurologic complications were related to screw malposition in 6 patients and epidural hematoma in 3 patients. New or more severe postoperative radicular symptoms were noted in 7 patients (0.7%). Psoas hematoma was identified by CT scan in 8 patients (0.8%). Complications directly related to rhBMP-2 were observed in at least 1 patient (0.1%) and in a worst case analysis, in as many as 6 patients (0.6%). CONCLUSION This study in 1037 patients confirms the relative safety of rhBMP-2/ACS for posterolateral spine fusion. There were extremely few complications directly attributed to rhBMP-2/ACS, and the overall complication rates were consistent with established norms. The stark contrast between this experience and the markedly elevated complication rate reported with anterior cervical BMP usage emphasizes the need to evaluate risks and benefits of bioactive technologies in a site-specific and procedure-specific manner.

Abstract
Clinicians use descriptive classification systems when treating patients with low back pain as an adjunct to surgical decision making. Magnetic resonance imaging (MRI) changes, including Modic changes, the presence of a high-intensity zone, and internal disk desiccation, are commonly used descriptors. The question remains whether different clinicians interpret these terms similarly. This study evaluated the inter- and intraobserver reliability of commonly used MRI classifications in patients presenting with low back pain.Sixty-six patients who underwent lumbar spine fusion surgery at a single multiphysician spine specialty practice for degenerative disk disease were identified. For each surgical level, the following MRI variables were determined independently by 3 fellowship-trained spine surgeons: presence or absence of high-intensity zone and/or internal disk desiccation, presence and classification of disk herniation, Modic grade, and disk height. Each surgeon reviewed the same set of MRI studies a second time at least 2 weeks from the first reading. Inter- and intraobserver reliability was determined using multiobserver Kappa coefficients. Intraobserver reliability ranged from 0.563 to 0.988, with greatest agreement in determining disk height. The greatest interobserver agreement was for determining Modic changes (0.819).Controversy remains on the criteria for diagnosing degenerative disk disease. In patients presenting with low back pain diagnosed with degenerative disk disease, the inter- and intraobserver reliability with use of several common MRI diagnostic tools was substantial. These data imply that clinicians interpret these findings in a reproducible fashion and interpret these terms similarly.

Abstract
BACKGROUND The value of lumbar spine arthrodesis in older patients is not well documented. As most of the literature regarding lumbar arthrodesis in older patients has focused on the prevalence of complications, the purpose of this study was to determine the clinical outcomes for older compared with younger patients undergoing lumbar arthrodesis. METHODS We studied 224 patients who underwent a single-level posterolateral lumbar arthrodesis with an iliac crest bone graft. Outcome measures included the Oswestry Disability Index, the Medical Outcomes Study Short Form-36 and numeric rating scales for back and leg pain, as well as a radiographic assessment of fusion. Outcome measures were evaluated on the basis of the mean change and the percentage of patients reaching a minimum clinically important difference threshold. For comparison, the patients were divided into two groups: 174 patients who were younger than sixty-five years and fifty patients who were sixty-five years of age or older. RESULTS Substantial improvements from baseline were noted in all of the clinical and health-related quality-of-life measures at the six-month, one-year, and two-year intervals. The mean improvements in the Oswestry Disability Index score at two years postoperatively were 28.5 points for the older patients and 24.5 points for the younger patients. For Short Form-36 physical component summary scores, the mean improvement from baseline was 14.2 points for the older group and 11.7 points for the younger group at two years. The older patients also demonstrated a similar or greater improvement in the numeric rating scale back and leg pain scores at all time intervals, with a significant difference in leg pain scores at two years postoperatively (10.4 points for the older patients and 6.4 points for the younger patients; p=0.002). Perioperative complications, although an obvious concern, did not appear to adversely affect clinical and health-related quality-of-life outcomes at two years postoperatively. CONCLUSIONS This study demonstrates a substantial benefit for patients sixty-five years of age or older with degenerative disc disease who are treated with a single-level lumbar decompression and instrumented arthrodesis, and we conclude that lumbar arthrodesis is a viable and reasonable treatment option for appropriately selected patients sixty-five years of age or older.

Abstract
BACKGROUND CONTEXT INFUSE has been proven effective in conjunction with threaded cages and bone dowels for single-level anterior lumbar interbody fusion (ALIF). The published experience with posterolateral fusion, although encouraging, utilizes a significantly higher dose and concentration of recombinant human bone morphogenic protein-2 (rhBMP-2) and a different carrier than the commercially available INFUSE. PURPOSE To present an assessment of fusion rate for posterolateral spine fusion with INFUSE Bone Graft. STUDY DESIGN/SETTING Retrospective review of patients treated using INFUSE in posterolateral spine fusion in a single institution. PATIENT SAMPLE 91 patients with minimum 2-year follow-up who underwent posterolateral spine fusion using INFUSE as an iliac crest bone graft (ICBG) substitute. OUTCOME MEASURES Fusion rate based on fine-cut computed tomographic (CT) scans with sagittal and coronal reconstructions. METHODS Fusion was performed using one large INFUSE kit (12 mg rhBMP-2, 1.5 mg/mL), which was prepared according to the manufacturer's instructions. The INFUSE sponge was wrapped around the local bone or graft extender and placed over the decorticated surfaces in the lateral gutters. Postoperative CT scans with reconstructions were reviewed by two independent orthopedic spine surgeons. CT scans of a comparison group of 35 patients who underwent primary single-level posterolateral fusion with ICBG were also reviewed. RESULTS The overall group had a mean 4.38 CT fusion grade and a 6.6% nonunion rate. Primary one-level fusion cases (n=48) had a mean 4.42 fusion grade a 4.2% nonunion rate. Primary multilevel fusions (n=27) had a mean 4.65 CT grade and no nonunions detected. Assessment of the 35 primary one-level ICBG control cases demonstrated a mean CT grade of 4.35 and a nonunion rate of 11.4%. In the 16 cases of revision for prior nonunion, mean CT grade was 3.81 and 4 subjects had nonunions. Additional subgroup analysis showed that smokers (n=14) had a mean 4.32 CT grade with no nonunions. Men had a mean 4.04 CT grade and an 11.1% nonunion rate compared with a mean 4.61 CT grade and 3.6% nonunion rate in women. This difference was statistically significant (p=.036). No significant differences in fusion rate were observed based upon the specific graft extender used (p=.200). CONCLUSIONS Posterolateral spine fusion involves a more difficult healing environment with a limited surface for healing, a gap between transverse processes and the milieu of distractive forces. Historically, only ICBG has been able to overcome these challenges and reliably generate a successful posterolateral lumbar spine fusion. In contrast to prior studies, clinically available INFUSE delivers only 12 mg rhBMP-2 at a concentration of 1.5 mg/mL. Despite the lower dose and concentration of rhBMP-2, this study suggests that fusion success with INFUSE is equivalent to ICBG for posterolateral spine fusion. As with ICBG, development of solid fusion or nonunion is a multifactorial process. The use of INFUSE is not a substitute for proper surgical technique or optimization of patient-related risk factors. Additional studies are needed to determine the incremental benefit of a greater rhBMP-2 dose or use of alternative carriers for posterolateral fusion. Finally, correlation between radiographic findings and clinical outcomes, and a cost-benefit analysis are needed. Despite these issues, this study presents compelling evidence that commercially available INFUSE is an effective ICBG substitute for one- and two-level posterolateral instrumented spine fusion.

Abstract
BACKGROUND CONTEXT Posterior fusion has been advocated as the most effective treatment of anterior cervical pseudoarthrosis. Authors cite the benefits of increased stability and avoiding the risk of dissection through anterior scar tissue. Despite these advantages, posterior fusion is a more extensive procedure from the standpoint of perioperative and postoperative recovery. PURPOSE The objective of this study is to compare the results of posterior fusions to revision anterior fusions for repair of anterior cervical pseudoarthrosis. STUDY DESIGN/SETTING This is a retrospective case series from a single institution. PATIENT SAMPLE 120 patients with nonunion documented on flexion-extension radiographs, computed tomography (CT) scan or tomograms after an anterior cervical discectomy and fusion with at least 2-year follow-up. OUTCOME MEASURES Surgical data, status of fusion, complications, and any revision surgeries. METHODS Hospital and office records were reviewed to determine demographic data, surgical data, status of fusion, and any revision surgeries. Nonunion was confirmed during surgery. RESULTS Of the 120 patients included in the study, 27 had repeat anterior procedures and 93 had posterior procedures. The proportion of smokers, the number of surgical levels, and the average time to revision in each group were similar. The average operative time for the anterior revision surgery was 134.9 minutes (range 49 to 232 minutes) with an estimated blood loss of 102.7 cc. In the posterior revision surgery the average operative time was 138.9 minutes (range 35 to 356 minutes) and an average estimated blood loss of 282.1 cc. The patients in the anterior revision group had an average hospital stay of 2.3 days (1 to 5 days), whereas those in the posterior revision group had an average hospital stay of 4.4 days (3 to 8 days). There was a 4% complication rate in the anterior revision group and an 8% complication rate in the posterior revision group. Twelve of 27 patients (44%) in the anterior revision group, and 2 of 93 patients in the posterior revision group required a second revision surgery for persistent nonunion. CONCLUSIONS Based on these results, posterior fusion is more effective in treating anterior cervical pseudoarthrosis than revision anterior fusion. The higher fusion rate and lower incidence of repeat revision surgery offset the increased blood loss and longer recovery time associated with posterior cervical fusions.

Abstract
BACKGROUND CONTEXT Patient-based quality of life scales have become a critical element of post-op assessment for lumbar fusion surgery. The most extensive outcomes data have been generated through FDA-regulated IDE trials for new technologies, which produce excellent data but are constrained by strict enrollment criteria and limited indications. This raises a question as to whether the excellent results seen in these IDE trials can be reproduced in standard clinical practice. PURPOSE The purpose of this study was to analyze surgical results based upon standardized outcome tools, across a spectrum of interventions, for one- and two-level lumbar spine fusion procedures. DESIGN/SETTING This study is a retrospective review of prospectively collected patient based outcomes data. PATIENT SAMPLE Four hundred ninety-seven patients, who underwent 1- or 2-level lumbar spine fusion at five participating spine centers, utilizing a variety of surgical techniques. Enrollment criteria included available demographic, surgical and clinical outcome data. At a minimum, patients had pre-op and one year post-op SF-36 data. In many cases two-year post-op SF-36 data and concomitant Oswestry Disability Index (ODI) data was available. OUTCOME MEASURES SF36 and ODI. METHODS The patient population included 270 females and 227 males, with a mean age of 47 years. Sixty-five percent (N=324) had one level fusions and 35% (N=173) had two level fusions. Demographic data collected included age, gender, BMI, surgical history, smoking history and work status. Data was analyzed with repeated measures analysis of variance (ANOVA). RESULTS SF-36 Physical Composite Score (PCS) improved a mean 9.9 points at one year post-op and 9.5 points at two years post-op. ODI improved a mean 22.2 points at one year post-op and 22.1 points at two years post-op. SF-36 PCS data for surgical approach subgroups revealed greater improvement (p=.03) in the ALIF group as compared to the PSF, PLIF/TLIF, or 360 degrees fusion groups (12.6 points vs. 8.8, 9.3, 8.4 points) at 1 year post-op. At 2 years post-op, there was greater improvement (p=.02) in the ALIF and PSF groups as compared to the PLIF/TLIF and 360 degrees fusion groups (13.8 and 11.2 points vs. 7.7 and 6.3 points). SF-36 PCS data demonstrated similar baseline scores for patients with and without prior decompression, but a significantly greater rate of improvement (11.3 vs. 7.2 points, p=.002) for patients without prior lumbar decompression surgery. The ODI data indicated a significantly greater disability at baseline in the prior decompression group, with greater improvement (21.7 vs. 17.5 points) in patients without prior surgery. CONCLUSIONS This study documents improved outcomes, based on SF-36 and ODI scores, in patients undergoing lumbar fusion for one and two level degenerative disc disease. The findings also demonstrate efficacy for all of the surgical techniques studied, suggesting that surgeons can appropriately select the surgical strategy with which they are most adept.

Abstract
BACKGROUND CONTEXT Prior studies have documented an increased complication rate in diabetics treated by lumbar decompression. Despite the assumption that this risk would be exacerbated in larger fusion procedures, a recent study found no such increased risk. PURPOSE To clarify the perioperative risk for patients with diabetes mellitus undergoing instrumented lumbar fusion as compared with controls. To identify differences, if any exist, between patients with insulin-dependent diabetes mellitus (IDDM) and non-insulin-dependent diabetes (NIDDM). STUDY DESIGN/SETTING This is a retrospective case-control study designed to examine the risk of perioperative complications in patients with diabetes mellitus treated by lumbar instrumentation and fusion. This study analyzed 94 diabetic patients and 43 controls treated by posterior lumbar instrumentation and fusion. Outcome was assessed based on the occurrence of perioperative complications. Complications were classified as major or minor. METHODS Hospital and office records were reviewed for 94 diabetics (51 NIDDM, 43 IDDM) and 43 controls matched for age, sex and procedure with the IDDM group. The groups were compared for demographic characteristics, surgical data, perioperative complications and fusion rate. RESULTS The NIDDM, IDDM and control groups were equivalent with regard to age, gender, nicotine use, fusion levels, operative time and estimated blood loss. There was a significant difference in complication rate between the NIDDM (53%) and IDDM (56%) groups versus controls (21%). There was a significant increase in complications with multilevel fusion in all groups and with increased operative time in the IDDM group. There was a significantly greater nonunion rate in the NIDDM (22%) and IDDM (26%) groups as compared with controls (5%). CONCLUSIONS Patients with both IDDM and NIDDM have a significantly increased risk of perioperative complications as compared with controls when treated by lumbar instrumentation and fusion.

Abstract
We studied 314 otherwise healthy children younger than 18 years of age with epicutaneous testing, and found that 20% of those tested had at least one positive epicutaneous test result. Neomycin, nickel, and potassium dichromate were the most prevalent allergens detected in our study group. We found that sensitization occurred at less than 5 years of age for all but fragrance allergens. Aluminum chambers and the American Academy of Dermatology Patch Test Kit were found to be safe for use in infants, children, and adolescents.
