Abstract
BACKGROUND The aim of this study was to evaluate the psychological distress pre-operatively, at 3, 6, and 12 months in patients who underwent lumbar spine fusion surgery. METHODS A total of 440 patients received instrumented lumbar spine fusion were enrolled. Psychological distress was evaluated using the Modified Somatic Perception Questionnaire (MSPQ) and the Modified Zung Depressive Index (ZDI). The results of lumbar fusion surgery were evaluated using the Oswestry Disability Index (ODI), the Japanese Orthopedic Association (JOA-29), and the visual analog scale (VAS). RESULTS Psychological distress was reported among 23% of patients and 7, 5.5, and 4.0% of the patients preoperatively, at 3, 6, and 12 months after lumbar surgery, respectively. The mean MSPQ score decreased from 8.78 (before surgery) to 4.30, 3.52, and 3.43 at 3, 6 and 12 months in after surgery, respectively, in patients with psychological distress patients (p < 0.001). The mean ZDI score decreased from 17.78 to 12.48, 10.35, and 9.61 (p < 0.001). The mean ODI score decreased from 22.91 to 11.78, 10.13, and 9.96 (P < 0.001). The mean JOA score increased from 13.65 to 22.30, 23.43, and 23.61 (P < 0.001). The mean low back pain (LBP) VAS score decreased from 4.48 to 1.96, 1.52, and 1.51 (P < 0.001); moreover, the mean leg pain (LP) VAS score decreased from 5.30 to 1.30, 1.04, and 1.03 (P < 0.001). CONCLUSIONS Patients with psychological distress may experience surgical intervention benefits equal to those of ordinary patients. Moreover, reduced pain and disability after surgical intervention may also alleviate psychological distress. Hence, we highly recommend that patients with psychological distress undergo surgical intervention as normal patients do, but appropriate screening measures and interventions are necessary.

Abstract
BACKGROUND It is incompletely understood how preoperative resilience affects 1-year postoperative outcomes after lumbar spinal fusion. METHODS Patients undergoing open lumbar spinal fusion at a single-center institution were identified between November 2019 and September 2022. Preoperative resilience was assessed using the Brief Resilience Scale. Demographic data at baseline including age, gender, comorbidities, and body mass index (BMI) were extracted. Patient-reported outcome measures including Oswestry Disability Index, PROMIS (Patient-Reported Outcomes Measurement Information System) Global Physical Health, PROMIS Global Mental Health (GMH), and EuroQol5 scores were collected before the surgery and at 3 months and 1 year postoperatively. Bivariate correlation was conducted between Brief Resilience Scale scores and outcome measures at 3 months and 1 year postoperatively. RESULTS Ninety-three patients had baseline and 1 year outcome data. Compared with patients with high resilience, patients in the low-resilience group had a higher percentage of females (69.4% vs. 43.9%; P = 0.02), a higher BMI (32.7 vs. 30.1; P = 0.03), and lower preoperative Global Physical Health (35.8 vs. 38.9; P = 0.045), GMH (42.2 vs. 49.2; P < 0.001), and EuroQol scores (0.56 vs. 0.61; P = 0.01). At 3 months postoperatively, resilience was moderately correlated with GMH (r = 0.39) and EuroQol (r = 0.32). Similarly, at 1 year postoperatively, resilience was moderately correlated with GMH (r = 0.33) and EuroQol (r = 0.34). Comparable results were seen in multivariable regression analysis controlling for age, gender, number of levels fused, BMI, Charlson Comorbidity Index, procedure, anxiety/depression, and complications. CONCLUSIONS Low preoperative resilience can negatively affect patient-reported outcomes 1 year after lumbar spinal fusion. Resiliency is a potentially modifiable risk factor, and surgeons should consider targeted interventions for at-risk patient groups.

Abstract
BACKGROUND CONTEXT Postoperative physical therapy (PT) following lumbar spinal fusion is an effective form of postoperative rehabilitation. However, it is unknown when a postoperative PT protocol should be optimally initiated. PURPOSE This study sought to compare lengths of stay between patients on a day zero PT protocol and those on a day one PT protocol. STUDY DESIGN/SETTING Retrospective chart review. PATIENT SAMPLE Patients who underwent lumbar spinal surgery at a large midwestern tertiary medical care center from January 1, 2018 through April 30, 2019 were eligible for their medical record's inclusion. PRIMARY OUTCOME MEASURE Length of hospital stay following surgery. METHODS Patients were stratified by having started postoperative PT on the same day as surgery (day zero) or having started postoperative PT on the day following surgery (day one). RESULTS A total of 164 patients were included in the study, 69 in the day zero group and 95 patients in the day one group. Most patients were female (59%, n = 98), and patients' average age was 62 years (SD = 13). Average length of stay was 61 hours (SD = 20) for those on the day zero protocol and 75 hours (SD = 32) for those on the day one protocol. CONCLUSIONS This study suggests that a postoperative physical therapy protocol initiated on day zero is associated with patients experiencing a shorter length of hospital stay compared to a similar PT protocol initiated on postoperative day one.

Abstract
PURPOSE To review existing classification systems for degenerative spondylolisthesis (DS), propose a novel classification designed to better address clinically relevant radiographic and clinical features of disease, and determine the inter- and intraobserver reliability of this new system for classifying DS. METHODS The proposed classification system includes four components: 1) segmental dynamic instability, 2) location of spinal stenosis, 3) sagittal alignment, and 4) primary clinical presentation. To establish the reliability of this system, 12 observers graded 10 premarked test cases twice each. Kappa values were calculated to assess the inter- and intraobserver reliability for each of the four components separately. RESULTS Interobserver reliability for dynamic instability, location of stenosis, sagittal alignment, and clinical presentation was 0.94, 0.80, 0.87, and 1.00, respectively. Intraobserver reliability for dynamic instability, location of stenosis, sagittal alignment, and clinical presentation were 0.91, 0.88, 0.87, and 0.97, respectively. CONCLUSION The UCSF DS classification system provides a novel framework for assessing DS based on radiographic and clinical parameters with established implications for surgical treatment. The almost perfect interobserver and intraobserver reliability observed for all components of this system demonstrates that it is simple and easy to use. In clinical practice, this classification may allow subclassification of similar patients into groups that may benefit from distinct treatment strategies, leading to the development of algorithms to help guide selection of an optimal surgical approach. Future work will focus on the clinical validation of this system, with the goal of providing for more evidence-based, standardized approaches to treatment and improved outcomes for patients with DS.

Abstract
INTRODUCTION The purpose of this study was to examine whether previous lumbar spinal fusion (LSF) was an independent risk factor for complications in patients undergoing total hip arthroplasty (THA) or hemiarthroplasty for displaced femoral neck fractures. METHODS AND MATERIALS An administrative database was queried from 2010 to Q2 of 2019 to analyze and compare complications in patients undergoing either THA or hemiarthroplasty for femoral neck fracture with a history of LSF versus no history of LSF. Joint complications including periprosthetic fracture, prosthetic joint infection (PJI), prosthetic joint dislocation (PJD), aseptic loosening, and prosthetic revision were examined at 90 days and 1 year post-operatively. RESULTS In the THA cohort, patients with prior LSF had significantly higher likelihood of aseptic loosening at 90 days and 1 year post-operatively in comparison to those without prior LSF (90-day: OR 2.22; 1-year: OR 1.95). Patients in the hemiarthroplasty cohort with prior LSF had significantly higher likelihood of PJI (90-day: OR 2.18; 1-year: OR 2.37), aseptic loosening (90-day: OR 3.42; 1-year: OR 4.68), and prosthetic revision (90-day: OR 2.27; 1-year: OR 2.25) in both the 90-day and 1-year postoperative period in comparison to those without prior LSF. Additionally, for the same cohort, periprosthetic fracture (1-year: OR 2.32) and PJD (1-year: OR 2.31) were significantly higher at 1-year postoperative. CONCLUSION Presence of LSF was found to be an independent risk factor for increased joint complications in patients undergoing either a THA or hemiarthroplasty for displaced femoral neck fractures.

Abstract
INTRODUCTION Patients with total hip arthroplasty (THA) and a concomitant lumbar spinal fusion (LSF) might have an increased incidence of revision surgery and postoperative complications such as early THA dislocation. The direct anterior approach (DAA) has gained popularity in THA due to its soft tissue-preserving nature and the relatively low dislocation risk. The purpose of the present study was to examine whether LSF patients undergoing minimally invasive THA through the DAA might have an increased risk of prosthetic-related complications compared to matched-control patients without a LSF. MATERIALS AND METHODS Patients who underwent THA through the DAA in our institution from January 2014 to December 2018 were identified. A total of 30 primary THA also underwent LSF within 3 months from the initial operation. These patients were randomly matched (1:3) for sex, age, and body mass index with patients who underwent primary THA in our institution without a history of LSF (control group). Peri and postoperative complications, revisions, radiographic and clinical outcomes were assessed retrospectively. RESULTS LSF patients who underwent THA through the DAA did not have an increased risk of prosthetic-related complications compared to matched-control subjects without a LSF (6.6% versus 4.4%, P < 0.05). The functional and radiological outcomes were similar between groups. CONCLUSION LSF patients undergoing THA could benefit from the DAA similarly to patients without LSF and without increased rate of early THA dislocation. Although the complex interplay between the lumbar spine and hip in THA patients warrants further investigation, the outcomes of THA through the DAA in LSF patients appear promising.

Abstract
PURPOSE The complex and dynamic spinopelvic interplay is not well understood. The aims of the present study were to investigate the following: (1) whether native acetabular anteinclination (AI) in standing position changes following lumbar spinal fusion (LSF); (2) potential correlations between AI change (ΔAI) and several spinopelvic parameters such as the change in lumbar lordosis (ΔLL), pelvic tilt (ΔPT), and anterior pelvic plane angle (ΔaPP). METHODS A total of 485 patients (Males: 262, Females: 223) with an average age of 64 ± 13 years who underwent a primary LSF were identified from our institutional database. The difference (Δ) between pre-and postoperative acetabular anteinclination (AI), lumbar lordosis (LL), anterior pelvic plane angle (aPP), sacral slope (SS), and pelvic tilt (PT) were measured on a standing lateral radiograph (EOS®) and compared to find the effect of LSF on the lumbopelvic geometry. RESULTS Following LSF, the average absolute ΔAI was 5.4 ± 4 (0 to 26)°, ΔLL: 5.5 ± 4 (0 to 27)°, ΔaPP: 5.4 ± 4 (0 to 38)°, ΔPT: 7 ± 5 (0 to 33)° and ΔSS: 5.3 ± 4 (0 to 33)°. No significant differences were observed between LSF levels. A ΔAI ≥ 10° was observed in 66 (13.6%) and ΔAI ≥ 20° in 5 (1%) patients. The Pearson correlation demonstrated a strong negative correlation of ΔAI with ΔLL (r = 0.72, p < .001). CONCLUSION Clinical decision-making should consider the relationship between native anteinclination and lumbar lordosis to reduce the risk of functional acetabular component malalignment in patients with concomitant hip and spine pathology.

Abstract
PURPOSE A radiologic assessment method to measure position change of screw-rod constructs over time by superposing the 3‑dimensional images assists in quantitative evaluation of screw loosening. We investigated the association between position change and radiolucent zone that was commonly used for diagnosing screw loosening. METHODS In this study 101 patients who underwent lumbar fusion were reviewed. Patient characteristics included age, sex, indications for surgery, number of fused levels, surgical procedures, and timing of follow-up computed tomography (CT, 1-5 months, 6-11 months, and ≥ 12 months). The Hounsfield unit values of L1 vertebra on preoperative CT were measured, and the radiolucent zone on each follow-up CT was evaluated. Using baseline CT on the day after surgery and follow-up CT, 3‑dimensional images of screw-rod constructs were generated and superposed. Position change was assessed by the median of the distances between the 3‑dimensional images at baseline and follow-up using the automated measurement method. Patient characteristics, the Hounsfield unit values of L1, and the amount of position change were categorized into the radiolucent zone presence and absence groups and compared. RESULTS The medians of position change were 0.281 mm and 0.136 mm in the radiolucent zone presence and absence groups, respectively (P < 0.001 by Mann-Whitney U-test). The area under the curve for position change in identifying radiolucent zone was 0.846; the cut-off value was 1.76 mm. In multivariable analysis, position change was independently associated with radiolucent zone (adjusted odds ratio per 0.1 mm, 2.80, 95% confidence interval 1.70-4.61). CONCLUSION Radiolucent zone was associated with position change of screw-rod constructs.

Abstract
PURPOSE To report the preliminary results of a novel full percutaneous interbody fusion technique for the treatment of degenerative disc disease (DDD) resistant to conservative treatment with posterior stabilization with rods and screws and transforaminal placement of an 8-mm-width intradiscal cage. MATERIALS AND METHODS A total of 79 patients with lumbar spine DDD resistant to medical therapy and/or spondylolisthesis up to grade 2 were treated. We performed preoperative X-rays, CT and MRI. The outcomes were assessed using the VAS score and the Oswestry Disability Index at a 1-, 6- and 12-month follow-up and also included X-rays to evaluate the correct bone fusion and the absence of complications. RESULTS Mean operation time was 130 min, and mean postoperative time until hospital discharge was 2 days. Postoperative values for VAS scores and ODI improved significantly compared to preoperative data: Mean preprocedural VAS was 7.49 ± 0.69 and decreased at 12-month follow-up to 1.31 ± 0.72, and mean preprocedural ODI was 29.94 ± 1.67 and decreased at 12-month follow-up to 12.75 ± 1.44. No poor results were reported, and no postprocedural sequelae were observed. CONCLUSIONS In our experience, this preliminary report shows a feasible and safe full percutaneous alternative procedure and represents a minimally invasive management of degenerative disc disease with low back pain resistant to medical therapy with or without lumbar spondylolisthesis up to grade 2.

Abstract
PURPOSE OF REVIEW The orientation of the spine relative to the pelvis-particularly that in the sagittal plane-has been shown in both kinematic and radiographic studies to be paramount in governance of acetabular alignment during normal bodily motion. The purpose of this review is to better understand the challenges faced by arthroplasty surgeons in treating patients that have concurrent lumbar disease and are therefore more likely to have poorer clinical outcomes after THA than in patients without disease. RECENT FINDINGS The concept of an "acetabular safe zone" has been well described in the past regarding the appropriate orientation of acetabular component in THA. However, this concept is now under scrutiny, and rising forth is a concept of functional acetabular orientation that is based on clinically evaluable factors that are patient and motion specific. The interplay between the functional position of the acetabulum and the lumbar spine is complex. The challenges that are thereby faced by arthroplasty surgeons in terms of proper acetabular cup positioning when treating patients with concomitant lumbar disease need to be better understood and studied, so as to prevent catastrophic and costly complications such as periprosthetic joint dislocations and revision surgeries.

Abstract
STUDY DESIGN Case report. OBJECTIVE We present a case of malignant peripheral nerve sheath tumor (MPNST) presenting as neuropathic pain in the setting of lumbar scoliosis and spinal stenosis. Most peripheral nerve sheath tumors are benign, and malignant cases are more commonly associated with neurofibromatosis type 1 or prior radiation exposure. MPNST is a rare tumor with a poor prognosis. We report a case of MPNST that presented as neuropathic pain following lumbar decompression and fusion surgery. METHODS A 60-year-old woman presented for management of lumbar scoliosis, stenosis, and left leg pain. After lumbar decompression and fusion surgery, the patient was readmitted to the hospital after falling 10 weeks post-op. She reported gradual recurrence of leg pain. Left foot drop was noted on exam. Imaging studies showed no spinal changes postoperatively or residual stenosis. Obesity limited electrodiagnostic studies. Hip MRI revealed a lobular soft tissue mass in the left sciatic notch. Surgical resection and pathology provided the diagnosis of MPNST. The patient declined wide resection and other interventions after seeking a second opinion. Palliative pain management was implemented. RESULTS The patient expired 15 months after her index spinal surgery. CONCLUSIONS MPNST is an extremely rare tumor that can present with symptoms similar to radiculitis. Clinical signs and symptoms of MPNST are vague and nonspecific due to compression of surrounding structures. Surgical wide resection is the first line of treatment for MPNST with chemotherapy and radiotherapy as adjuvant treatments. MPNST has a poor prognosis with reported 5-year survival ranging from 16 to 54%. This case demonstrates the need to pursue additional workup when diagnostic imaging and objective findings do not satisfactorily explain the clinical presentation. LEVEL OF EVIDENCE IV.

Abstract
Background Posterior lumbar fusion is a widely accepted surgical technique; however, it has been related to the possibility of paraspinal muscle atrophy after surgery. We investigated 1-year postoperative changes in paraspinal muscle volume using a simple formula applicable to magnetic resonance imaging (MRI) or computed tomography (CT) images. Methods Patients with degenerative lumbar spinal stenosis who underwent posterior interbody fusion (PLIF) at the L4/5 level in the period from May 2010 to June 2017 were enrolled in this study. Radiologic parameters were measured using MRI or CT images which were taken before surgery and at 1 year after surgery. The volume of the paraspinal muscles was calculated using a simple formula which was derived from the formula for calculating the volume of truncated elliptic cones. Results A total of 40 patients were included; 24 were analyzed using MRI and 16 were analyzed using CT. The mean age of the patients was 59.6 ± 12.1 years and 32 (80.5%) were female. When comparing the preoperative and 1-year-postoperative images, multifidus muscle (MF) reduction was consistently observed in the MRI and CT groups, right and left (p = 0.003, p < 0.001, p = 0.005 and p < 0.001, respectively). In the erector spinae (ES) group, decrease in muscle volume was observed in the right-sided muscles of the CT group (p < 0.001), but no significant change was observed in the MRI group. The psoas muscle showed no significant change after 1 year. Conversely, regression analysis showed a negative correlation between MF muscle volume loss and age in the MRI group (right and left, p = 0.002 and p = 0.015, respectively), that is, the younger the age, the greater loss of muscle mass. Conclusion After the posterior lumbar fusion, the volume of the MF muscles was markedly decreased, and the degree of decrease was apparent in the MRI. The volume of the ES muscles, which are located relatively laterally, also tended to decrease at 1 year after surgery.

Abstract
PURPOSE A variety of alternative grafts to autologous iliac crest bone (ICBG) have been developed for lumbar spondylodesis, due to frequent complications following ICBG harvest. The optimal alternative graft to ICBG, however, remains elusive till now. The purpose of this study was to compare the efficacy and safety of fusion materials in lumbar degeneration diseases and to provide a ranking spectrum of the grafts. METHODS Randomized controlled trials (RCTs) comparing different bone grafts in lumbar arthrodesis were eligible for inclusion. A network meta-analysis was performed for endpoints including fusion rate and incidence of adverse events. RESULTS Twenty-seven RCTs involving 2488 patients and 13 available interventions were included. rhBMP-2 provided the highest fusion rate, being significantly superior to that of ICBG (OR = 0.21, p < 0.001), autograft local bone (ALB) (OR = 0.18, p = 0.022), rhBMP-7 (OR = 0.15, p < 0.001), allograft (OR = 0.13, p = 0.009), and DBM + ALB (OR = 0.07, p = 0.048). The treatment efficacy of allograft could be significantly enhanced by bone marrow concentrate (BMC) supplying (OR = 0.16, p = 0.010). ICBG ranks second on the frequency of complications, which is significantly higher than that of allograft (OR = 0.14, p = 0.041) and ALB (OR = 0.14, p = 0.030). All of the other comparisons showed similar efficacy and safety profiles between groups. CONCLUSION Ranking spectrums of the efficacy and safety for various bone grafts were provided graphically. Though rhBMP-2 was of the highest success rate, the application should be taken with proper caution because of the widely proposed life-threatening adverse events. ALB, ALB plus synthetic ceramic materials and allograft mixed with BMC were also proved to be potentially effective alternative graft to ICBG.

Abstract
BACKGROUND In the move toward value-based care, bundled payments are believed to reduce waste and improve coordination. Some commercial insurers have addressed this through the use of bundled payment, the provision of one fee for all care associated with a given index procedure. This system was pioneered by Medicare, using a population generally over 65 years of age, and despite its adoption by mainstream insurers, little is known of bundled payments' ability to reduce variation or cost in a working-age population. This study uses a universally-insured, nationally-representative population of adults aged 18-65 to examine the effect of bundled payments for five high-cost surgical procedures which are known to vary widely in Medicare reimbursement: hip replacement, knee replacement, coronary artery bypass grafting (CABG), lumbar spinal fusion, and colectomy. METHODS Five procedures conducted on adults aged 18-65 were identified from the TRICARE database from 2011 to 2014. A 90-day period from index procedure was used to determine episodes of associated post-acute care. Data was sorted by Zip code into hospital referral regions (HRR). Payments were determined from TRICARE reimbursement records, they were subsequently price standardized and adjusted for patient and surgical characteristics. Variation was assessed by stratifying the HRR into quintiles by spending for each index procedure. RESULTS After adjusting for case mix, significant inter-quintile variation was observed for all procedures, with knee replacement showing the greatest variation in both index surgery (107%) and total cost of care (75%). Readmission was a driver of variation for colectomy and CABG, with absolute cost variation of $17,257 and $13,289 respectively. Other post-acute care spending was low overall (≤$1606, for CABG). CONCLUSIONS This study demonstrates significant regional variation in total spending for these procedures, but much lower spending for post-acute care than previously demonstrated by similar procedures in Medicare. Targeting post-acute care spending, a common approach taken by providers in bundled payment arrangements with Medicare, may be less fruitful in working aged populations.

Abstract
BACKGROUND CONTEXT The influence of rheumatoid arthritis (RA) on the lumbar spine has received relatively little attention compared with cervical spine, and few studies have been conducted for adjacent segment disease (ASD) after lumbar fusion in patients with RA. PURPOSE The present study aims to determine the incidence of ASD requiring surgery (ASDrS) after short lumbar fusion and to evaluate risk factors for ASDrS, including RA. STUDY DESIGN This is a retrospective cohort study. PATIENT SAMPLE The present study included 479 patients who underwent lumbar spinal fusion of three or fewer levels, with the mean follow-up period of 51.2 (12-132) months. OUTCOME MEASURES The development of ASD and consequent revision surgery were reviewed using follow-up data. METHODS The ASDrS-free survival rate of adjacent segments was calculated through Kaplan-Meier method. The log-rank test and Cox regression analysis were used to evaluate risk factors comprising RA, age, gender, obesity, osteoporosis, diabetes, smoking, surgical method, and the number of fusion segments. RESULTS After short lumbar fusion, revision surgery for ASD was performed in 37 patients (7.7%). Kaplan-Meier analysis predicted that the ASDrS-free survival rate of adjacent segments was 97.8% at 3 years, 92.7% at 5 years, and 86.8% at 7 years. In risk factor analysis, patients with RA showed a 4.5 times higher risk of ASDrS than patients without RA (p<.001), and patients with three-segment fusion showed a 2.7 times higher risk than patients with one- or two-segment fusion (p=.005). CONCLUSIONS Adjacent segment disease requiring surgery was predicted in 13.2% of patients at 7 years after short lumbar fusion. Rheumatoid arthritis and the number of fusion segments were confirmed as risk factors.

Abstract
BACKGROUND The degenerative lumbar spinal stenosis is one of the most commonly treated spinal disorders in older adults; despite its increasing frequency, it is not yet clear what the most effective therapy might be. The aim of this study is to investigate the very long term results of a homogenized cohort of patients suffering from lumbar spinal stenosis: the first subset of patients operated on with laminectomy and the second subset of patients was also advised to undergo laminectomy but never operated on. METHODS Patients from both subgroups were advised to undergo surgery, according to the same criteria, in the period between 2000 and 2010 and were re-evaluated in the period between January and December 2016. RESULTS Comparing the two subsets of patients, both suffering from clinically relevant LSS, the first subset returns a statistically significant clinical improvement at follow-up. The rate of excellent results decreases over years. Iatrogenic spinal instability incidence was found to be 3.8% in the present cohort. CONCLUSIONS Although the improvement of the first postoperative years decreases over time and despite the lack of general consensus, the lack of established shared guidelines and the limitations of this research, the results support the utilisation of surgery for the management of this condition.

Abstract
Lumbar interbody fusion is currently the gold standard in treating patients with disc degeneration or segmental instability. Despite it having been used for several decades, the non-union rate remains high. A failed fusion is frequently attributed to an inadequate mechanical environment after instrumentation. Finite element (FE) models can provide insights into the mechanics of the fusion process. Previous fusion simulations using FE models showed that the geometries and material of the cage can greatly influence the fusion outcome. However, these studies used axisymmetric models which lacked realistic spinal geometries. Therefore, different modeling approaches were evaluated to understand the bone-formation process. Three FE models of the lumbar motion segment (L4-L5) were developed: 2D, Sym-3D and Nonsym-3D. The fusion process based on existing mechano-regulation algorithms using the FE simulations to evaluate the mechanical environment was then integrated into these models. In addition, the influence of different lordotic angles (5, 10 and 15°) was investigated. The volume of newly formed bone, the axial stiffness of the whole segment and bone distribution inside and surrounding the cage were evaluated. In contrast to the Nonsym-3D, the 2D and Sym-3D models predicted excessive bone formation prior to bridging (peak values with 36 and 9% higher than in equilibrium, respectively). The 3D models predicted a more uniform bone distribution compared to the 2D model. The current results demonstrate the crucial role of the realistic 3D geometry of the lumbar motion segment in predicting bone formation after lumbar spinal fusion.

Abstract
BACKGROUND Chronic low back pain is a common health problem for adult workers and causes an enormous economic burden. With the improvement of minimally invasive surgical techniques (MIS) in spinal fusion and the development of fusion devices, more lumbar operations are today being performed through a less invasive technique. When compared with open surgeries (OS), MIS has demonstrated better clinical outcomes including operation time, blood loss, complication rates and length of hospital stay. The aim of this review was to identify and summarize evidence on the time to return to work and the duration of post-operation narcotic use for patients who had lumbar spinal fusion operations using MIS and OS techniques. METHODS A systematic literature review was performed including studies identified from PubMed, EMBASE, the Cochrane Collaboration, and the Centre for Review and Dissemination (CRD) (January 2004–April 2014) for publications reporting on time to return to work and post-operation narcotic use after MIS or OS lumbar spinal fusion surgeries. RESULTS Out of a total of 36 included studies, 28 reported on the time to return to work and 17 on the narcotic use after MIS or OS. Four studies described the time to return to work directly comparing MIS and OS. Three studies, from the US, directly compared the duration of narcotic use between MIS- transforaminal lumbar interbody fusion (TLIF) and OS-TLIF. In addition to the time to return to work, 23 studies reported on the rate of return to work and the employment rate before and after surgery, and two Swedish studies presented sick leave data. CONCLUSION There is a gap of good quality data describing the time to return to work and narcotic use after lumbar spinal fusion operations using MIS or OS techniques. However, the current systematic literature review indicates that patients who have lumbar spinal fusion operations, with the MIS procedure, generally return to work after surgery more quickly and require less post-operation narcotics for pain control compared to patients who have OS.

Abstract
BACKGROUND CONTEXT Adjacent segment degeneration (ASD) is one of the major complications after lumbar fusion. Several studies have evaluated the risk factors of ASD. Although the paraspinal muscles play an important role in spine stability, no study has assessed the relationship between paraspinal muscle atrophy and the incidence of ASD after lumbar fusion. PURPOSE In the present study, we aimed to verify the known risk factors of ASD, such as body mass index (BMI), preoperative adjacent facet joint degeneration, and disc degeneration, and to assess the relationship between paraspinal muscle atrophy and ASD. STUDY DESIGN This is a retrospective 1:1 pair analysis matched by age, sex, fusion level, and follow-up period. PATIENT SAMPLE To calculate the appropriate sample size for the study, we performed a pre-study analysis of the paraspinal muscle cross-sectional area (CSA), and estimated that at least 35 cases would be needed for each group. Among the 510 patients who underwent posterior lumbar fusion for degenerative lumbar disease between January 2009 and October 2009, a total of 50 patients with ASD after surgery were selected. Another group of 50 matched patients with degenerative lumbar disease without ASD after spinal fusion were selected as the control group. Each patient in the ASD group was matched with a control patient according to age, sex, fusion level, and follow-up period. OUTCOME MEASURES Radiographic measurements and demographic data were reviewed. METHODS The risk factors considered were higher BMI, preoperative adjacent segment disc and facet degeneration, and preoperative paraspinal muscle atrophy and fatty degeneration. The radiographic data were compared between the ASD and control groups to determine the predictive factors of ASD after posterior lumbar fusion by using logistic regression analysis. The study was not externally funded. The authors have no conflict of interest to declare. RESULTS Multivariate logistic regression analysis indicated that higher BMI (odds ratio [OR]: 1.353, p=.008), preoperative facet degeneration on computed tomography examination (OR: 3.075, p=.011), disc degeneration on magnetic resonance imaging (MRI) (OR: 2.783, p=.003), fatty degeneration (OR: 1.080, p=.044), and a smaller relative CSA of the paraspinal muscle preoperatively (OR: 0.083, p=.003) were significant factors for predicting the development of ASD. CONCLUSIONS The occurrence of radiological ASD is most likely multifactorial, and is associated with a higher BMI, preexisting facet and disc degeneration on preoperative examination, and a smaller preoperative relative CSA of the paraspinal muscle on MRI.

Abstract
BACKGROUND Catastrophic thinking and fear-avoidance belief are negatively influencing severe acute pain following surgery causing delayed ambulation and discharge. We aimed to examine if a preoperative intervention of cognitive-behavioural therapy (CBT) could influence the early postsurgical outcome following lumbar spinal fusion surgery (LSF). METHODS Ninety patients undergoing LSF due to degenerative spinal disorders were randomly allocated to either the CBT group or the control group. Both groups received surgery and postoperative rehabilitation. In addition, the CBT group received a preoperative intervention focussed on pain coping using a CBT approach. Primary outcome was back pain during the first week (0-10 scale). Secondary outcomes were mobility, analgesic consumption, and length of hospitalisation. Data were retrieved using self-report questionnaires, assessments made by physical therapists and from medical records. RESULTS No difference between the groups' self-reported back pain (p = 0.76) was detected. Independent mobility was reached by a significantly larger number of patients in the CBT group than the control group during the first three postoperative days. Analgesic consumption tended to be lower in the CBT group, whereas length of hospitalisation was unaffected by the CBT intervention. CONCLUSION Participation in a preoperative CBT intervention appeared to facilitate mobility in the acute postoperative phase, despite equally high levels of self-reported acute postsurgical pain in the two groups, and a slightly lower intake of rescue analgesics in the CBT group. This may reflect an overall improved ability to cope with pain following participation in the preoperative CBT intervention. TRIAL REGISTRATION The study was approved by the Danish Protection Agency (2011-41-5899) and the Ethics Committee of the Central Denmark Region (M-20110047). The trial was registered in Current Controlled Trials ( ISRCTN42281022 ).

Abstract
PURPOSE This meta-analysis aimed to evaluate the efficacy of motion-preservation procedures to prevent the adjacent segment degeneration (ASDeg) or adjacent segment disease (ASDis) compared with fusion in lumbar spine. METHODS PubMed, Embase and the Cochrane Library were comprehensively searched and a meta-analysis was performed of all randomized controlled trials and well designed prospective or retrospective comparative cohort studies assessing the lumbar fusion and motion-preservation procedures. We compared the ASDeg and ASDis rate, reoperation rate, operation time, blood loss, length of hospital stay, visual analogue scale (VAS) and oswestry disability index (ODI) improvement of the two procedures. RESULTS A total of 15 studies consisting of 1474 patients were included in this study. The meta-analysis indicated that the prevalence of ASDeg, ASDis and reoperation rate on the adjacent level were lower in motion-preservation procedures group than in the fusion group (P = 0.001; P = 0.0004; P < 0.0001). Moreover, shorter length of hospital stay was found in motion-preservation procedures group (P < 0.0001). No difference was found in terms of operation time (P = 0.57), blood loss (P = 0.27), VAS (P = 0.76) and ODI improvement (P = 0.71) between the two groups. CONCLUSIONS The present evidences indicated that the motion-preservation procedures had an advantage on reducing the prevalence of ASDeg, ASDis and the reoperation rate due to the adjacent segment degeneration compared with the lumbar fusion. And the clinical outcomes of the two procedures are similar.

Abstract
BACKGROUND CONTEXT Lumbar degenerative spondylolisthesis (DS) is a common, acquired condition leading to disabling back and/or leg pain. Although surgery is common used to treat patients with severe symptoms, there are no universally accepted treatment guidelines. Wide variation in vertebral translation, disc collapse, sagittal alignment, and vertebral mobility suggests this is a heterogeneous disease. A classification scheme would be useful to differentiate homogenous subgroups that may benefit from different treatment strategies. PURPOSE To develop and test the reliability of a simple, clinically useful classification scheme for lumbar DS. STUDY DESIGN Retrospective case series. PATIENT SAMPLE One hundred twenty-six patients. OUTCOME MEASURES Proposed radiographic classification system. METHODS A classification system is proposed that considers disc space height, sagittal alignment and translation, and the absence or presence of unilateral or bilateral leg pain. Test cases were graded by six observers to establish interobserver reliability and regraded in a different order 1 month later to establish intraobserver reliability using Kappa analysis. To establish the relative prevalence of each subtype, a series of 100 consecutive patients presenting with L4-L5 DS were classified. RESULTS Four radiographic subtypes were identified: Type A: advanced Disc space collapse without kyphosis; Type B: disc partially preserved with translation of 5 mm or less; Type C: disc partially preserved with translation of more than 5 mm; and Type D: kyphotic alignment. The leg pain modifier 0 denotes no leg pain, 1 denotes unilateral leg pain, and 2 represents bilateral leg pain. The Kappa value describing interobserver reliability was 0.82, representing near-perfect agreement. Intraobserver reliability analysis demonstrated Kappa=0.83, representing near-perfect agreement. Grading of the consecutive series of 100 patients revealed the following distribution: 16% Type A, 37% Type B, 33% Type C, and 14% Type D. CONCLUSIONS A new radiographic and clinical classification scheme for lumbar DS with high inter- and intraobserver reliabilites is proposed. Use of this classification scheme should facilitate communication to enhance the quality of outcomes research on DS.

Abstract
AIM: To ascertain current surgeon practice in the United Kingdom National Health Service for the management of patients undergoing lumbar spinal fusion surgery.
METHODS: Descriptive survey methodology utilised an online questionnaire administered through SurveyMonkey. Eligible participants were all surgeons currently carrying out lumbar spinal fusion surgery in the National Health Service. Two previous surveys and a recent systematic review informed questions. Statistical analyses included responder characteristics and pre-planned descriptive analyses. Open question data were interpreted using thematic analysis.
RESULTS: The response rate was 73.8%. Most surgeons (84%) were orthopaedic surgeons. Range of surgeon experience (1-15 years), number of operations performed in the previous 12 mo (4-250), and range of information used to predict outcome was broad. There was some consistency of practice: most patients were seen preoperatively; all surgeons ensured patients are mobile within 3 d of surgery; and there was agreement for the value of post-operative physiotherapy. However, there was considerable variability of practice: variability of protocols, duration of hospital stay, use of discharge criteria, frequency and timing of outpatient follow up, use of written patient information and outcome measures. Much variability was explained through patient-centred care, for example, 62% surgeons tailored functional advice to individual patients.
CONCLUSION: Current United Kingdom surgeon practice for lumbar spinal fusion is described. The surgical procedure and patient population is diverse, and it is therefore understandable that management varies. It is evident that care should be patient-centred. However with high costs and documented patient dissatisfaction it is important that further research evaluates optimal management.

Abstract
BACKGROUND CONTEXT Systematic reviews of lumbar fusion outcomes in purely workers' compensation (WC) patient populations have indicated mixed results for efficacy. Recent studies on lumbar fusions in the WC setting have reported return-to-work rates of 26% to 36%, reoperation rates of 22% to 27%, and high rates of persistent opioid use 2 years after surgery. Other types of lumbar surgery in WC populations are also acknowledged to have poorer outcomes than in non-WC. The possibility of improving outcomes by employing a biopsychosocial model with a continuum of care, including postoperative functional restoration in this "at risk" population, has been suggested as a possible solution. PURPOSE To compare objective socioeconomic and patient-reported outcomes for WC patients with different lumbar surgeries followed by functional restoration, relative to matched comparison patients without surgery. STUDY DESIGN/SETTING A prospective cohort study of chronic disabling occupational lumbar disorder (CDOLD) patients with WC claims treated in an interdisciplinary functional restoration program. PATIENT SAMPLE A consecutive cohort of 564 patients with prerehabilitation surgery completed a functional restoration and was divided into groups based on surgery type: lumbar fusion (F group, N=331) and nonfusion lumbar spine surgery (NF group, N=233). An unoperated comparison group was matched for length of disability (U group, N=349). OUTCOME MEASURES Validated patient-reported measures of pain, disability, and depression were administered pre- and postrehabilitation. Socioeconomic outcomes were collected via a structured 1-year "after" interview. METHODS All patients completed an intensive, medically supervised functional restoration program combining quantitatively directed exercise progression with a multimodal disability management approach. The writing of this article was supported in part by National Institutes of Health Grant 1K05-MH-71892; no conflicts of interest are noted among the authors. RESULTS The F group had a longer length of disability compared with the NF and U groups (M=31.6, 21.7, and 25.9 months, respectively, p<.001). There were relatively few statistically significant differences for any socioeconomically relevant outcome among groups, with virtually identical postrehabilitation return-to-work (F=81%, NF=84%, U=85%, p=.409). The groups differed significantly after surgery on diagnosis of major depressive disorder and opioid dependence disorder as well as patient-reported depressive symptoms and pain intensity prerehabilitation. However, no significant differences in patient-reported outcomes were found postrehabilitation. Prerehabilitation opioid dependence disorder significantly predicted lower rates of work return and work retention as well as higher rates of treatment-seeking behavior. Higher levels of prerehabilitation perceived disability and depressive symptoms were significant risk factors for poorer work return and retention outcomes. CONCLUSIONS Lumbar surgery in the WC system (particularly lumbar fusion) have the potential achieve positive outcomes that are comparable to CDOLD patients treated nonoperatively. This study suggests that surgeons have the opportunity to improve lumbar surgery outcomes in the WC system, even for complex fusion CDOLD patients with multiple prior operations, if they control postoperative opioid dependence and prevent an excessive length of disability. Through early referral of patients (who fail to respond to usual postoperative care) to interdisciplinary rehabilitation, the surgeon determining this continuum of care may accelerate recovery and achieve socioeconomic outcomes of relevance to the patient and WC jurisdiction through the combination of surgery and postoperative rehabilitation.

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