Abstract
BACKGROUND Reoperation after lumbar spine surgery is a major issue for both patients and physicians. It is uncertain whether fusion is superior to decompression alone for lumbar degenerative disease regarding reoperation rate. We aim to evaluate the reoperation rate after fusion surgery for lumbar degenerative disease compared with decompression alone. METHODS This study was conducted under a retrospective cohort design in patients undergoing fusion or decompression alone in one or two levels for lumbar degenerative disease using a Japanese claims-based database. Primary outcome was reoperation incidence during the follow-up period, and secondary outcome was reoperation incidence within 90 days postoperatively. Confounding factors were handled using propensity score overlap weighting. Cumulative incidence of reoperation was calculated from the Kaplan-Meier curve and hazard ratios (HRs) and 95% confidence intervals (CIs) for reoperation were estimated using Cox proportional hazards regression models. RESULTS 8497 patients (2051 patients in the fusion group and 6446 in the decompression alone group) were included in the study. There was no difference in reoperation rate between fusion and decompression alone (weighted HR 0.85 [95% CI 0.69 to 1.04]; p = 0.11). CONCLUSIONS Among patients with lumbar degenerative disease who underwent fusion or decompression alone, no significant difference was observed between the two groups.

EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2025; 34:43-49. [PMID: 39589507 DOI: 10.1007/s00586-024-08578-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 10/11/2024] [Accepted: 11/18/2024] [Indexed: 11/27/2024]
Abstract
PURPOSE Destructive spondyloarthropathy (DSA) is a serious complication of long-term haemodialysis; it commonly occurs in the cervical spine and has been investigated in cervical lesions. Although DSA of the lumbar spine has been reported, only few studies have investigated this, and the characteristics of patients with lumbar DSA are unclear. The present study aimed to elucidate the prevalence of DSA and its clinical characteristics in patients with DSA in the lumbar spine using computed tomography (CT) images of the patients who underwent lumbar spine surgery. METHODS Consecutive patients undergoing haemodialysis who underwent lumbar spine surgery (n = 67) were assessed. DSA was diagnosed using CT images, and the patients were divided into non-DSA and DSA groups. The differences in the clinical characteristics of the patients in the two groups were analysed. RESULTS The prevalence of patients diagnosed with DSA was 31.3%. The mean intra- and inter-observer kappa values of DSA classification using CT images were 0.68 and 0.53, respectively. Although there were no significant differences in the age, sex, body mass index, reason for lumbar surgery, disease causing haemodialysis, age at the start of haemodialysis, or duration of haemodialysis between the non-DSA and DSA groups, the duration of haemodialysis tended to be longer in the DSA group. CONCLUSION Among patients on haemodialysis who underwent lumbar spine surgery, the prevalence of patients with DSA was 31.3%. Classification of DSA using CT showed moderate-to-substantial agreement. Patients with DSA tended to have a longer haemodialysis duration.

Abstract
Patients with dialysis are at high risk of reoperation after lumbar spinal fusion surgery. However, the risk of reoperation after short-segment (≤2 fusion levels) lumbar spinal fusion surgery in this patient group has not been completely investigated. This study aimed to compare the risk of reoperation after short-segment lumbar spinal fusion surgery between patients with dialysis and matched controls without dialysis. We retrospectively evaluated 85 patients who underwent short-segment lumbar spinal fusion surgery at a single institution. Based on the current dialysis treatment, patients were divided into the non-dialysis and dialysis groups. We compared the patients' characteristics, surgical data, pre- and postoperative radiographic measurements, locomotive functional levels in activities of daily living (ADL), rate of whole reoperation, and cause-specific incidence of reoperation such as adjacent segmental disease (ASD) and implant failure between the non-dialysis and dialysis groups. Then, these variables were compared after adjusting for age, sex, and body mass index (BMI) via a propensity-score-matched analysis. In total, 68 patients in the non-dialysis group and 17 patients in the dialysis group were included in this study. The dialysis group was significantly younger and had a lower postoperative ADL status than the non-dialysis group. Moreover, the dialysis group had a significantly higher rate of whole reoperation (8.8% vs 41.2%, P = .003), reoperation due to ASD (4.4% vs 23.5%, P = .027), and reoperation due to implant failure (0.8% vs 11.8%, P = .038) than in the non-dialysis group. Based on a propensity-score-matched analysis, the dialysis group had a significantly higher rate reoperation rate after short-segment lumbar spinal fusion surgery than the non-dialysis group (0.0% vs 58.3%, P = .005). The current study firstly clarified that patients with dialysis are at significantly high risk of reoperation even after short-segment lumbar spinal fusion surgery.

Long-term outcomes of spine surgery in dialysis patients, focusing on activities of daily living, life expectancy, and the risk factors for postoperative mortality. J Orthop Sci 2024; 29:508-513. [PMID: 36894404 DOI: 10.1016/j.jos.2023.02.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 02/14/2023] [Accepted: 02/21/2023] [Indexed: 03/11/2023]
Abstract
BACKGROUND Because of the high incidence of major perioperative adverse events, spine surgery in dialysis patients should be recommended carefully after consideration of its risks and benefits. However, the benefits of spine surgery in dialysis patients remain unclear because of the lack of long-term outcomes. The purpose of this study is to elucidate the long-term outcomes of spine surgery in dialysis patients, focusing on activities of daily living (ADLs), life expectancy, and risk factors for postoperative mortality. METHODS Data for 65 dialysis patients who underwent spine surgery at our institution and were followed up for a mean duration of 6.2 years were retrospectively reviewed. ADLs, number of surgeries, and survival times were recorded. The postoperative survival rate was calculated using the Kaplan-Meier method, and risk factors for postoperative mortality were investigated using a generalized Wilcoxon test and multivariate Cox proportional-hazards model. RESULTS Compared with preoperative ADLs, ADLs significantly improved at discharge after surgery and at the final follow-up. However, 16 of the 65 patients (24.6%) underwent multiple surgeries, and 34 (52.3%) died during the follow-up period. Kaplan-Meier analysis revealed that the survival rate after spine surgery was 95.4% at 1 year, 86.2% at 3 years, 69.6% at 5 years, 59.7% at 7 years, and 28.7% at 10 years, and the overall median survival time was 99 months. Multivariate Cox regression analysis showed that a dialysis period of ≥10 years was a significant risk factor. CONCLUSIONS Spine surgery in dialysis patients improved and maintained ADLs in the long term and did not shorten life expectancy. However, dialysis patients undergoing spine surgery require multiple surgeries more frequently, and a dialysis period of ≥10 years is a significant risk factor for postoperative mortality.

Clinical Outcomes of Lateral Lumbar Interbody Fusion with Percutaneous Pedicle Screw for Dialysis-Related Spondyloarthropathy. J Clin Med 2024; 13:1089. [PMID: 38398402 PMCID: PMC10889300 DOI: 10.3390/jcm13041089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 02/04/2024] [Accepted: 02/10/2024] [Indexed: 02/25/2024] Open
Abstract
Background: The usefulness and problems with lateral lumbar interbody fusion (LLIF) with a percutaneous pedicle screw (PPS) for dialysis-related spondyloarthropathy are not clear. Therefore, we investigated the usefulness and problems with LLIF with PPS in dialysis-related spondyloarthropathy. Methods: In total, 77 patients who underwent LLIF with PPS were divided into two groups: the dialysis-related spondyloarthropathy group ("Group D") consisted of 15 patients (10 males and 5 females) with a mean age of 70.4 years and a mean duration of hemodialysis of 10.8 years; and the lumbar degenerative disease group ("Group L") included 62 patients (31 males and 31 females) with a mean age of 71.0 years. The mean follow-up period was 4 years in Group D and 3 years 9 months in Group L. We compared surgical invasiveness (operative time, blood loss), perioperative complications, clinical outcomes (Improvement ratio of the JOA score), bone fusion rate, reoperation, sagittal alignment, and coronal imbalance between the two groups. Results: There were no significant differences in operative time, blood loss, or the improvement ratio of the JOA score, but dialysis-related spondyloarthropathy was observed in one patient with superficial infection, three patients with endplate failure, and one patient with restenosis due to cage subsidence. Conclusions: We consider LLIF with PPS for dialysis-related spondyloarthropathy to be an effective treatment option because its surgical invasiveness and clinical outcomes were comparable to those for cases of lumbar degenerative disease. However, as endplate failure due to bone fragility and a reduced bone fusion rate were observed in dialysis spondylolisthesis cases, we advise a careful selection of indications for indirect decompression as well as the application of suitable pre- and postoperative adjuvant therapies.

Abstract
INTRODUCTION Adjacent segment degeneration is among the most recognized long-term complications of lumbar surgery for degenerative spine pathologies with a relevant impact in spine surgical and clinical practice. It is reported a incidence of clinical adjacent segment disease between 5-30% of patients undergoing spinal fusion. We aimed to evaluate the main clinical and surgical risk factors for developing adjacent segment disease. EVIDENCE ACQUISITION A systematic review and meta-analysis of the pertinent literature was performed, according to PRISMA and PICO guidelines, focusing on clinical and radiological adjacent segment disease. We exclusively included studies reporting demographic and clinical data, and surgical details published from 30 September 2015 to 30 September 2020. The effect of considered risk factors on the presence of adjacent segment disease was explored with a random-effects model. EVIDENCE SYNTHESIS A total of 15 scientific publications, corresponding to 6253 patients, met the inclusion criteria for the qualitative and quantitative analysis. 720 of the patients developed a clinical and/or radiological adjacent syndrome disease, and 473 have been surgically managed. Ten articles qualified for the comparative geographical analysis. Advanced age and obesity are relevant risk factors for developing lumbar adjacent segment degeneration. Our data also reported a higher prevalence of adjacent segment degeneration in Western populations than in Eastern populations. The interbody fusion has a protective role toward lumbar adjacent segment degeneration. CONCLUSIONS This study highlighted multifactorial issues regarding adjacent segment disease: clinical, anatomical, biomechanical, and radiological features. In view of increasing life expectancy and spinal surgery procedures, extensive multicenter studies will be needed to define the correct management of the adjacent segment disease.

A Novel Grading System of Destructive Lumbar Spondyloarthropathy Based on Evaluation of the Facet Joints. Spine (Phila Pa 1976) 2022; 47:1227-1233.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To develop and evaluate a new grading system for destructive lumbar spondyloarthropathy (DLSA) by assessing bony destruction of the facet joints; to evaluate interrater reliability; and to determine the association between anteroposterior (AP) dural sac diameter at the lumbar level and the new grading. SUMMARY OF BACKGROUND DATA The characteristics of DLSA are unknown, hindering clinical care and research. Imaging to determine the cause of DLSA may positively contribute to patient outcome or well-being by providing prognostic information. PATIENTS AND METHODS In the magnetic resonance images (MRIs), we measured an axial midline AP dural sac diameter and evaluated bone destruction caused by amyloidosis at the level of the center of each lumbar disk of the lumbar spine. Two orthopedic surgeons independently evaluated each case at two-month intervals and assigned the grade by rating bone destruction at each lumbar level. Weighted κ and intraclass correlation coefficients for interrater reliability were calculated. In addition, the correlation between the AP diameter of the spinal dural sac at the lumbar level and the new MRI-based DLSA grade was examined. RESULTS The sample size of 82 patients was reached by examining records of 118 consecutive patients. The mean (SD) age of the included patients was 65 (7.2) years, and 36 (43.9%) were women. The grading of DLSA showed moderate to good interrater reliability at both assessments (κ, 0.59-0.78). Intraclass correlation coefficient showed substantial to excellent agreement (intraclass correlation coefficient, 0.63-0.86). The AP diameter of the spinal dural sac at the lumbar level showed a significant correlation with the new grading ( P <0.001). CONCLUSIONS The new MRI-based grading system for DLSA has good interrater reliability, although the strength of agreement varies somewhat. The new grading system correlates with AP dural sac diameter. Thus, this classification focused on facet erosion, which leads to functional incompetence may be helpful in surgical decision-making.

Abstract
Study Design Clinical case series. Purpose This study aimed to report dynamization-posterior lumbar interbody fusion (PLIF), our surgical treatment for hemodialysisrelated spondyloarthropathy (HSA), and investigate patients' postoperative course within 2 years. Overview of Literature HSA often requires lumbar fusion surgery. Conventional PLIF for HSA may cause progressive destructive changes in the vertebral endplate, leading to progressive cage subsidence, pedicle screw loosening, and pseudoarthrosis. A dynamic stabilization system might be effective in patients with a poor bone quality. Thus, we performed "dynamization-PLIF" in hemodialysis patients with destructive vertebral endplate changes. Methods We retrospectively examined patients with HSA who underwent dynamization-PLIF at our hospital between April 2010 and March 2018. The radiographic measurements included lumbar lordosis and local lordosis in the fused segment. The evaluation points were before surgery, immediately after surgery, 1 year after surgery, and 2 years after surgery. The preoperative and postoperative radiographic findings were compared using a paired t-test. A p-value of less than 0.05 was considered significant. Results We included 50 patients (28 males, 22 females). Lumbar lordosis and local lordosis were significantly improved through dynamization- PLIF (lumbar lordosis, 28.4°-35.5°; local lordosis, 2.7°-12.8°; p<0.01). The mean local lordosis was maintained throughout the postoperative course at 1- and 2-year follow-up (12.9°-12.8°, p=0.89 and 12.9°-11.8°, p=0.07, respectively). Solid fusion was achieved in 59 (89%) of 66 fused segments. Solid fusion of all fixed segments was achieved in 42 cases (84%). Within 2 years postoperatively, only six cases (12%) were reoperated (two, surgical debridement for surgical site infection; two, reoperation for pedicle screw loosening; one, laminectomy for epidural hematoma; one, additional fusion for adjacent segment disease). Conclusions Dynamization-PLIF showed local lordosis improvement, a high solid fusion rate, and a low reoperation rate within 2 years of follow-up.

Correlation between Preoperative Serum Levels of Calcium, Phosphate, and Intact Parathyroid Hormone and Radiological Outcomes in Spinal Interbody Fusion among End-Stage Renal Disease Patients. J Clin Med 2021; 10:jcm10225447.

Abstract
Spinal fusion surgery for end-stage renal disease (ESRD) patients is a clinical challenge. This study aimed to investigate whether postoperative radiological outcomes are related to preoperative serum calcium, phosphate, or intact parathyroid hormone (iPTH) levels in patients with ESRD who underwent spinal interbody fusion surgery. This study included 62-consecutive patients with ESRD who underwent anterior cervical discectomy and fusion (ACDF) or transforaminal lumbar interbody fusion (TLIF) surgery for symptomatic spinal disorder. The most recent preoperative serum calcium, phosphate, and iPTH levels were recorded, and the postoperative radiographic outcomes were assessed. A significant correlation was found between the occurrence of cage subsidence and higher blood phosphate, calcium–phosphate product (Ca × P), and iPTH levels in the TLIF group. The occurrence of pedicle screw loosening was related to higher blood phosphate and Ca × P product in the TLIF group. However, no correlation was found between the fusion grades and the serum levels in either the TLIF or ACDF groups. These results indicated that higher preoperative serum phosphate and Ca × P product are risk factors for both cage subsidence and screw loosening in patients with ESRD who underwent TLIF surgery. Higher iPTH levels are also a possible risk factor for cage subsidence.

Abstract
Postoperative cervical deformity sometimes occurs in the short or long term after primary surgery for cervical disorders related to the degenerative aging spine, neoplastic etiologies, hemodialysis, infection, inflammation, trauma, etc. Cervical kyphosis after posterior decompression surgery, such as laminectomy or laminoplasty, is a common problem for spine surgeons. However, revision surgery for cervical deformity is definitely one of the most challenging areas for spine surgeons. There is no doubt that surgery for cervical deformity carries a high risk of surgery-related complications that might result in aggravation of health-related quality of life. Revision surgery is even more challenging. Hence, spine surgeons need to assess carefully the overall severity of the underlying condition before revision surgery, and try to refine the surgical strategy to secure safe surgery. Needless to say, spine surgeons are now facing great challenges in making spine surgery a much more reliable and convincing entity.

Clinical outcomes after posterior cervical decompression and fusion surgery for destructive spondyloarthropathy in patients undergoing long-term hemodialysis: A matched case-control study. J Orthop Sci 2019; 24:404-408. [PMID: 30420294 DOI: 10.1016/j.jos.2018.10.019] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Revised: 10/08/2018] [Accepted: 10/21/2018] [Indexed: 11/29/2022]
Abstract
BACKGROUND Cervical destructive spondyloarthropathy (DSA) often leads to cervical myelopathy in long-term hemodialysis patients. However, the surgical outcomes after instrumented fusion surgery for cervical DSA are still unclear. The objective of this study was to investigate the clinical outcomes of cervical DSA in comparison with a control group. MATERIALS AND METHODS A consecutive series of 20 undergoing long-term hemodialysis patients who underwent instrumented fusion surgery for cervical DSA between 2010 and 2016 were included in this study (DSA group). The mean age at surgery was 65 years, and there were 11 men and 9 women. The average length of hemodialysis was 23 years. The age- and sex-matched control group consisted of 20 patients (degenerative conditions). The Japanese Orthopedic Association (JOA) score, recovery rate, complications, and loss of correction of fused level were compared between the groups. RESULTS Two of the 20 patients died due to perioperative complications. More than 1 year of follow-up data after surgery was available for 18 patients. The mean JOA score significantly increased from 5.4 before surgery to 9.7 at 1 year after surgery and 8.3 at the final follow-up (mean: 33.2 ± 21.3 months, P = 0.019). There were no significant differences in the mean recovery rate (41% vs. 37%, P = 0.44) between the DSA group and control group. Loss of correction of more than 5°was significantly higher in the DSA group (44% vs. 10%, P = 0.027). The rate of pseudarthrosis (17% vs. 5%, P = 0.328) and adjacent segment disease (22% vs. 10%, P = 0.17) tended to be higher in the DSA group. DISCUSSION The clinical outcomes showed significant recovery in both groups. Therefore, posterior cervical decompression and fusion surgery was effective for treating cervical DSA.

Clinical comparison between simple laminectomy and laminectomy plus posterior instrumentation in surgical treatment of cervical myelopathy. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2019; 29:975-982. [PMID: 30737557 DOI: 10.1007/s00590-019-02395-6] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Accepted: 02/04/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Posterior stabilization in patients treated with laminectomy for spondylotic cervical myelopathy is still a debate. Despite both being reported in literature by several authors, some controversies still exist. The aim of this study is to compare clinical and radiological outcomes in patients treated with laminectomy or laminectomy with posterior stabilization. MATERIAL AND METHODS We retrospectively evaluated 42 patients affected by cervical myelopathy (mean age 70.43 ± 5.03 years), 19 treated with laminectomy (group A) and 23 with laminectomy and posterior instrumentation (group B). Neurological status was assessed with Nurick scale, pain with VAS and radiological parameters with C2-C7 SVA, T1 slope and C2-C7 lordosis, clinical function with modified Japanese Orthopaedic Association score (JOA). Also, surgery time and blood loss were recorded. Student's t test was used for continuous variables, while Kruskal-Wallis test was used for categorical values. RESULTS No differences were found in postoperative Nurick scale (p = 0.587), VAS (p = 0.62), mJOA (p = 0.197) and T1 slope (p = 0.559), while laminectomy with fusion showed better postoperative cervical lordosis (p = 0.007) and C2-C7 SVA (p < 0.00001), but higher blood loss (p < 0.00001) and surgical time (p < 0.00001). Both groups showed better Nurick scale (p = 0.00017 for group A and p = 0.00081 for group B), VAS (p = 0.02 for group A and p = 0.046 for group B) and mJOA (p < 0.00001 for both groups) than preoperative values. CONCLUSIONS Both treatments are a valuable choice, offering some benefits and disadvantages against each other. Each procedure must be carefully evaluated on the basis of patients' general status, preoperative pain, signs of instability and potential benefits from cervical alignment correction.

Dialysis is an independent risk factor for perioperative adverse events, readmission, reoperation, and mortality for patients undergoing elective spine surgery. Spine J 2018; 18:2033-2042. [PMID: 30077772 DOI: 10.1016/j.spinee.2018.04.007] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2018] [Revised: 03/15/2018] [Accepted: 04/09/2018] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT The prevalence of dialysis-dependent patients in the United States is growing. Prior studies evaluating the risk of perioperative adverse events for dialysis-dependent patients are either institutional cohort studies limited by patient numbers or administrative database studies limited to inpatient data. PURPOSE The present study uses a large, national sample with 30-day follow-up to investigate dialysis as risk factor for perioperative complications independent of patient demographics or comorbidities. STUDY DESIGN/SETTING This is a retrospective cohort study. PATIENT SAMPLE Patients undergoing elective spine surgery with or without dialysis from the 2005-2015 National Surgical Quality Improvement Program (NSQIP) database were included in the study. OUTCOME MEASURES Postoperative complications within 30 days and binomial reoperation, readmission, and mortality within 30 days were determined. METHODS The 2005-2015 NSQIP databases were queried for adult dialysis-dependent and dialysis-independent patients undergoing elective spinal surgery. Differences in 30-day outcomes were compared using risk-adjusted multivariate regression and coarsened exact matching analysis for adverse events, unplanned readmission, reoperation, and mortality. The percentage of complications occurring before versus after hospital discharge was also assessed. The authors have no financial disclosures related to the present study. RESULTS A total of 467 dialysis and 173,311 non-dialysis patients met the inclusion criteria. Controlling for age, gender, body mass index, functional status, and American Society of Anesthesiologists (ASA) class, dialysis patients were found to be at significantly greater odds of any adverse event (odds ratio [OR]=2.52 before, 2.17 after matching, p=<.001), major adverse event (OR=2.90 before, 2.52 after matching, p=<.001), and minor adverse event (OR=1.50 before matching, p=<.025, but not significantly different after matching). Further, dialysis patients were significantly more likely to return to the operating room (OR=2.77 before, 2.50 after matching, p=<.001), have unplanned readmissions (OR=2.73 before, 2.37 after matching, p=<.001), and die within 30 days (OR=3.77 before, 2.71 after matching, p=<.001). Adverse events occurred after discharge for 51.78% of non-dialysis patients and for 43.80% of dialysis patients. CONCLUSIONS Dialysis patients undergoing elective spine surgery are at significantly higher risk of aggregated adverse outcomes, return to the operating room, readmission, and death than non-dialysis patients, even after controlling for patient demographics and overall health (as indicated by ASA class). These differences need to be considered when determining treatment options. Additionally, with bundled payments expected in spine surgery, physicians and hospitals need to account for increased costs and liabilities when working with dialysis patients.

Abstract
BACKGROUND Patients with end-stage renal disease (ESRD) are at an increased risk of surgical mortality. We aimed to investigate the factors associated with in-hospital mortality in patients with ESRD who underwent spinal surgery, which remains to be determined. MATERIAL AND METHODS An age- and sex-matched cohort study was conducted using the Taiwan Longitudinal Health Insurance Database between January 2000 and December 2012. Kaplan-Meier curves were plotted with log-rank test to compare the differences between these 2 groups. The Cox proportional hazard model was used to estimate the hazard ratio of in-hospital mortality adjusted with potential confounding. RESULTS In total, 4109 participants with pre-existing ESRD and 8218 patients without ESRD were included. The in-hospital mortality in ESRD (10.17%) was greater than without ESRD (1.39%). Spinal surgery patients with pre-existing ESRD had a 6.78-fold increase in-hospital mortality risk compared with those without ESRD. Spinal surgery patients with ESRD of any age, male or female, and comorbidities experienced a greater incidence of hospital mortality. In patients with ESRD, operations on spinal cords and spinal canal structures had the greatest hospital mortality (14.87%) compared with spinal fusion (3.46%) or excision or destruction of intervertebral disc (3.01%). Kaplan-Meier survival curves showed that patients with ESRD experienced greater hospital mortality than patients without ESRD in all 3 spinal surgery methods (log rank P < 0.0001). CONCLUSIONS Spinal surgery patients with ESRD have greater in-hospital mortality than patients without ESRD. Age, sex, history of comorbidities, and types of surgical methods were associated with greater in-hospital mortality among patients with ESRD.
