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 2023:10.1007/s00586-023-08065-w. [PMID: 38148366 DOI: 10.1007/s00586-023-08065-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 11/22/2023] [Accepted: 11/23/2023] [Indexed: 12/28/2023]
Abstract
OBJECTIVE Spondylodiscitis refers to infection of the intervertebral disk and neighboring structures. Outcomes based on instrumentation type are not well reported in the literature, but are important in establishing guidelines for surgical management of spondylodiscitis. This study aims to clarify the effect of instrumentation material selection on clinical and radiographic outcomes in patients with spondylodiscitis. METHODS Studies that evaluated the use of polyetheretherketone (PEEK), titanium, allograft, and/or autologous bone grafts for spondylodiscitis were identified in the literature. Radiographic and clinical data were analyzed using a meta-analysis of proportions, with estimated risk and confidence intervals reported for our primary study outcomes. RESULTS Thirty-two retrospective studies totaling 1088 patients undergoing surgical management of spondylodiscitis with PEEK, TTN, allograft, and autologous bone graft instrumentation were included. There were no differences in fusion rates (p-interaction = 0.55) with rates of fusion of 93.4% with TTN, 98.6% with allograft, 84.2% with autologous bone graft, and 93.9% with PEEK. There were no differences in screw loosening (p-interaction = 0.52) with rates of 0.33% with TTN, 0% with allograft, 1.3% with autologous bone graft, and 8.2% with PEEK. There were no differences in reoperation (p-interaction = 0.59) with rates of 2.64% with TTN, 0% with allograft, 1.69% with autologous bone graft, and 3.3% with PEEK. CONCLUSIONS This meta-analysis demonstrates that the choice of instrumentation type in the surgical management of spondylodiscitis resulted in no significant differences in rate of radiographic fusion, screw loosening, or reoperation. Future comparative studies to optimize guidelines for the management of spondylodiscitis are needed.

Zheng HL, Li B, Song SK, Chen PB, Zheng XF, Jiang LS, Jiang SD. Safety and Efficacy of Polyetheretherketone (PEEK) Cages and Cadaveric Allografts in Transforaminal Lumbar Interbody Fusion (TLIF) for Treating Lumbar Pyogenic Spondylodiscitis. Mediators Inflamm 2023; 2023:5171620. [PMID: 37284349 PMCID: PMC10241573 DOI: 10.1155/2023/5171620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 01/26/2023] [Accepted: 04/05/2023] [Indexed: 06/08/2023] Open
Abstract
Purpose There have been many studies in the operative management of pyogenic spondylodiscitis with foreign materials. However, it still remains an issue of debate on whether the allografts may be used in pyogenic spondylodiscitis. This study sought to evaluate the safety and effectiveness of PEEK cages and the cadaveric allograft in transforaminal lumbar interbody fusion (TLIF) for treating lumbar pyogenic spondylodiscitis. Methods From January 2012 to December 2019, 56 patients underwent surgery for lumbar pyogenic spondylodiscitis. The posterior debridement of all patients and their fusion with allografts, local bone grafts, and bone chip cages were performed before posterior pedicle screw fusion. An assessment of the residual pain, the grade of neurological injury, and the resolution of infection was conducted on 39 patients. The clinical outcome was evaluated using a visual analog scale (VAS) and the Oswestry Disability Index (ODI), and neurological outcomes were appraised based on Frankel grades. The radiological outcomes were evaluated via focal lordosis, lumbar lordosis, and the state of the fusion. Results Staphylococcus aureus and Staphylococcus epidermidis were the most common causative organisms. The mean preoperative focal lordosis was -1.2° (-11.4° to 5.7°), and the mean postoperative focal lordosis increased to 10.3° (4.3°-17.2°). At the final follow-up, there were five cases with subsidence of the cage, no case of recurrence, and no case with cage and screw loosening or migration. The mean preoperative VAS and ODI scores were 8.9 and 74.6%, respectively, and improvements in VAS and ODI were 6.6 ± 2.2 and 50.4 ± 21.3%, respectively. The Frankel grade D was found in 10 patients and grade C in 7. Following the final follow-up, only one patient improved from Frankel grade C to grade D while the others recovered completely. Conclusion The PEEK cage and cadaveric allograft combined with local bone grafts is a safe and effective choice for intervertebral fusion and restoring sagittal alignment without increased incidence of relapse for treating lumbar pyogenic spondylodiscitis.

Abstract
Background A limited number of studies are available in the literature on the surgical treatment of brucellosis-related spondylodiscitis. This study aimed to define and discuss the role of surgery in brucellosis-related spondylodiscitis. Methodology A total of 28 patients who underwent surgical treatment due to brucellosis-related spondylodiscitis between February 2021 and August 2022 were included in this study. Medical records, radiological images, and laboratory data were collected. Surgical results were evaluated according to the Visual Analog Scale (VAS) and Oswestry Disability Index (ODI). C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels, clinical findings, postoperative radiological imaging findings, and complications were evaluated. Results In total, 16 of the patients included in the study were male and 12 were female, with a mean age of 56.4 ± 7.2 years. The mean follow-up duration was 11.8 ± 5.4 months. Brucellosis involvement was in the lumbosacral region in all patients. Overall, 21 patients had a neurological deficit in the preoperative period. Posterior stabilization and fusion were done in 20 (71.4%) patients, while simple laminectomy (decompression) and debridement were done in eight (28.6%) patients. There was a decrease in the pain in the lower back and leg in all patients in the postoperative period. Neurological recovery was achieved in 18 patients with a neurological deficit. Two patients underwent wound drainage in the postoperative period. The patient who had morbid obesity and comorbidities died in the postoperative period. ESR and CRP levels returned to normal at the end of the six-month follow-up. There was a significant recovery in VAS and ODI scores (p < 0.05). In total, 24 (85.4%) patients were considered fully recovered both radiologically and clinically at the end of the follow-up. Conclusions Although long-term and specific antibiotic treatment constitute the main treatment in brucellosis-related spondylodiscitis, debridement, decompression, and stabilization (when required) of infection with a focus on neurological deficits and instability formation and non-stop severe pain are effective and safe treatment options.

Abstract
BACKGROUND Despite advances, the morbidity and mortality rates of patients with spondylodiscitis remains high, with an increasing incidence worldwide. Although conservative therapy has progressed, several cases require surgical intervention. However, the indication and opportunities for surgical treatment are still disputable. METHODS In a joint consensus, the members of the 'Spondylodiscitis' working group of the Spine Section of the German Society for Orthopaedics and Trauma Surgery considered current literature, particularly the newly published S2k guideline of the AWMF, and examined the surgical indications and treatment strategies for thoracolumbar spondylodiscitis. RESULTS Surgical intervention for spondylodiscitis is only required in a small percentage of patients. In studies comparing conservative and surgical therapies, most patients benefitted from surgery, regardless of the surgical technique selected. Presently, the standard procedure is a combined dorsoventral approach, in which a monolateral attempt should always be made. The choice of material (PEEK, titanium) for ventral support does not influence the clinical result.

Abstract
BACKGROUND Antibiotic resistant infectious spondylodiscitis (IS) can cause significant morbidity for patients. Open surgical techniques were previously the only option for patients who failed antibiotic therapy. However, advances in minimally invasive surgical techniques may provide a new alternative for some patients. METHODS A systematic review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology to identify studies that reported inflammatory [erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)] and functional outcomes [visual analog scale (VAS)] for patients with antibiotic resistant IS treated with either minimally invasive or open surgery. Searches were preformed using PubMed, Embase, and Scopus from January 2015 to June 2021. Fourteen articles met inclusion criteria. One study was a Level III evidence study and the other 13 included studies were Level IV. RESULTS The minimally invasive surgery group showed significantly lower post-operative CRP and VAS pain scores and significantly higher post-operative ESR levels than the open group. All studies included were measured by the Downs and Black tool for potential bias. DISCUSSION This study showed that minimally invasive surgery is efficacious in the treatment of antibiotic resistant IS. These outcomes support minimally invasive surgery (MIS) as an effective alternative to previous open surgery techniques in certain patients after failed trails of antibiotic therapy.

PMMA-Cement-PLIF Is Safe and Effective as a Single-Stage Posterior Procedure in Treating Pyogenic Erosive Lumbar Spondylodiscitis—A Single-Center Retrospective Study of 73 Cases. Bioengineering (Basel) 2022; 9:bioengineering9020073. [PMID: 35200426 PMCID: PMC8869766 DOI: 10.3390/bioengineering9020073] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2021] [Revised: 12/29/2021] [Accepted: 02/08/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Surgical treatment for erosive pyogenic spondylodiscitis of the lumbar spine is challenging as, following debridement of the intervertebral and bony abscess, a large and irregular defect is created. Sufficient defect reconstruction with conventional implants using a posterior approach is often impossible. Therefore, we developed the “Cement-PLIF”, a single-stage posterior lumbar procedure, combining posterior lumbar interbody fusion (PLIF) with defect-filling using antibiotic-loaded polymethylmethacrylate (PMMA). This study first describes and evaluates the procedure’s efficacy, safety, and infection eradication rate. Radiological implant stability, bone-regeneration, sagittal profile reconstruction, procedure-related complications, and pre-existing comorbidities were further analyzed. Methods: A retrospective cohort study analyzing 73 consecutive patients with a minimum of a one-year follow-up from 2000–2017. Patient-reported pain levels and improvement in infectious serological parameters evaluated the clinical outcome. Sagittal profile reconstruction, anterior bone-regeneration, and posterior fusion were analyzed in a.p. and lateral radiographs. A Kaplan–Meier analysis was used to determine the impact of pre-existing comorbidities on mortality. Pre-existing comorbidities were quantified using the Charlson-Comorbidity Index (CCI). Results: Mean follow-up was 3.3 (range: 1–16; ±3.2) years. There was no evidence of infection persistence in all patients at the one-year follow-up. One patient underwent revision surgery for early local infection recurrence (1.4%). Five (6.9%) patients required an early secondary intervention at the same level due to minor complications. Radiological follow-up revealed implant stability in 70/73 (95.9%) cases. Successful sagittal reconstruction was demonstrated in all patients (p < 0.001). There was a significant correlation between Kaplan–Meier survival and the number of pre-existing comorbidities (24-months-survival: CCI ≤ 3: 100%; CCI ≥ 3: 84.6%; p = 0.005). Conclusions: The Cement-PLIF procedure for pyogenic erosive spondylodiscitis is an effective and safe treatment as evaluated by infection elimination, clinical outcome, restoration, and maintenance of stability and sagittal alignment.

Abstract
Study Design Retrospective case-control study. Purpose This study aimed to analyze the radiological and clinical outcomes of transpedicular decompression in spinal tuberculosis (or Pott’s spine) with and without anterior reconstruction using polyetheretherketone (PEEK) or mesh cage. Overview of Literature The outcomes of transpedicular decompression with and without global reconstruction in Pott’s spine are insufficiently investigated. Additionally, the use of PEEK cages in Pott’s spine has remained unestablished. Methods Using the hospital records and imaging database obtained from January 2014 to January 2020, this study retrospectively analyzed patients who underwent surgery for Pott’s spine and met the eligibility criteria. Results This study included 230 patients with a mean±standard deviation age of 47.7±18.1 years (109 males, 121 females). The Visual Analog Scale score, Oswestry Disability Index, and Cobb angle were significantly improved in these patients (p<0.001). Patients who underwent anterior reconstruction had a greater correction in Cobb angle postoperatively (p=0.042) but also had a greater blood loss (p=0.04). During the follow-up, they experienced a significant loss of correction compared with those who only underwent transpedicular decompression (p=0.026). Nevertheless, patients who underwent anterior reconstruction using mesh/PEEK cages showed no significance difference in the clinical or radiological outcomes. Conclusions Transpedicular decompression used in the surgical management of Pott’s spine showed favorable clinical and radiological outcomes. The additional use of anterior reconstruction obtained equivalent clinical outcomes but resulted in excessive blood loss. Meanwhile, the use of mesh/PEEK cage for anterior reconstruction did not affect the clinical and radiological outcomes.

Abstract
Background Posterolateral decompression and debridement in patients with TB spine led to defect in the anterior column which makes the spinal column unstable, thus making anterior column reconstruction an important step in surgical management. Objective Through the study, authors sought to answer the following questions: 1) What are the differences in clinical outcomes between patients with TB spine undergoing anterior column reconstruction using titanium mesh cage versus PEEK cage? 2) What are the differences in radiological outcomes between these two groups of patients? Methods This is a retrospective comparative study including patients with TB spine undergoing surgical management. The included subjects were divided into groups A and B depending on the implantation of PEEK or titanium mesh cage respectively for anterior column reconstruction. Outcome criteria analyzed included clinical criteria like VAS and ODI scores, radiological criteria like kyphosis correction, loss of kyphosis at follow-up, cage subsidence, and bony fusion on a 2D CT scan. Results The study population included 14 patients in Group A and 15 patients in Group B. Improvement in VAS and ODI scores was comparable between groups. There was no significant difference in radiological outcome measures between the two groups, however, two patients from group B showed implant-related complications needing revision. All patients showed good bony fusion at the final follow-up. Conclusion PEEK and titanium cages have comparable clinico-radiological outcomes for anterior column reconstruction in patients with active TB spine. Its advantages for being radiolucent and its ease of use may make it a choice of implant.

Abstract
PURPOSE Surgical intervention with intercorporal stabilisation in spinal infections is increasingly needed. Our aim was to compare titanium and polyetheretherketon (PEEK) cages according to their adhesion characteristics of different bacteria species in vitro. METHODS Plates made from PEEK, polished titanium (Ti), two-surface-titanium (TiMe) (n = 2-3) and original PEEK and porous trabecular structured titanium (TiLi) interbody cages (n = 4) were inoculated in different bacterial solutions, S.aureus (MSSA, MRSA), S.epidermidis and E.coli. Growth characteristics were analysed. Biofilms and bacteria were visualised using confocal- and electron microscopy. RESULTS Quantitative adherence of MSSA, MRSA, S.epidermidis and E.coli to Ti, TiMe and PEEK plates were different, with polished titanium being mainly advantageous over PEEK and TiMe with significantly less counts of colony forming units (CFU) for MRSA after 56 h compared to TiMe and at 72 h compared to PEEK (p = 0.04 and p = 0.005). For MSSA, more adherent bacteria were detected on PEEK than on TiMe at 32 h (p = 0.02). For PEEK and TiLi cages, significant differences were found after 8 and 72 h for S.epidermidis (p = 0.02 and p = 0.008) and after 72 h for MSSA (p = 0.002) with higher bacterial counts on PEEK, whereas E.coli showed more CFU on TiLi than PEEK (p = 0.05). Electron microscopy demonstrated enhanced adhesion in transition areas. CONCLUSION For S.epidermidis, MSSA and MRSA PEEK cages showed a higher adherence in terms of CFU count, whereas for E.coli PEEK seemed to be advantageous. Electron microscopic visualisation shows that bacteria did not adhere at the titanium mesh structure, but at the border zones of polished material to rougher parts.

Abstract
OBJECTIVE Spondylodiscitis and vertebral osteomyelitis cause significant morbidity and mortality, and typically occur in patients with multiple comorbidities. The use of minimally invasive spinal surgery in the previous decade has offered the advantages of reduced intraoperative blood loss and postoperative pain for patients. In the present report, we have described our experience with using a hybrid minimally invasive (HMI) technique (combining percutaneous fixation with a mini-open approach for decompression and debridement) for the treatment of thoracolumbar spondylodiscitis, reporting the patient demographics, intraoperative measures, and 12-month outcomes. METHODS The data from patients presenting to a tertiary referral neurosurgical center with thoracolumbar spondylodiscitis and osteomyelitis who had undergone HMI from 2016 to 2018 were retrospectively evaluated. Patient demographics, intraoperative factors, estimated blood loss, and immediate postoperative complications were recorded. The patient outcomes were evaluated using EuroQOL 5-dimension questionnaire and visual analog scale in the immediate postoperative period and at 12 months postoperatively. RESULTS A total of 13 patients were included in the present study, 12 with spontaneous infection and 1 with infection secondary to recent microdiscectomy at another institution. All the patients had systemic comorbidities with an American Society of Anesthesiologists class of ≥2. Of the 13 patients, 11 had pyogenic infections and 2 had spinal tuberculosis. The mean estimated blood loss was 546.2 mL. The mean time for patients to sit out of bed was 2.2 days, and the mean time to start mobilizing was 4.5 days. The EuroQOL 5-dimension questionnaire scores showed improvement in all modalities at 12 months postoperatively. CONCLUSIONS In our cohort, HMI was a safe and effective treatment of thoracolumbar spondylodiscitis, with the potential benefits of reduced blood loss, operative duration, and postoperative pain.

Abstract
The objective of study was to evaluate a case series of patients in whom polyetheretherketone (PEEK) cages were used for anterior column reconstruction in vertebral osteomyelitis. Fifteen patients underwent clinical and radiological evaluation with average follow-up of 26 months. Parameters assessed were time of surgery, blood loss, segmental kyphosis or lordosis angle, time to solid bony fusion, ambulatory status, and functional outcome. Mean time of surgery was 150 min with mean blood loss of 530 ml. One patient died in early postoperative period. All patients without preoperative neurologic deficit were walking unaided first day postoperatively. Solid bony fusion was demonstrated in 14 patients, on average 7.1 months postoperatively. Functional outcome at the latest follow-up was excellent, good, or fair in 86%. Two failures with recurrent infection were treated with PEEK cage removal and reinstrumentation. High success rate could be expected when PEEK cages are used for anterior column support in pyogenic vertebral osteomyelitis.

Abstract
Despite the plethora of evidence in support of the use of structural osseous autograft in lumbar spondylodiscitis, attention has recently been turned to the addition of synthetic materials such as polyetheretherketone (PEEK) to restore anterior vertebral column support.From January 2015 to April 2017, 7 patients with lumbar polymicrobial spondylodiscitis were surgically treated with a minimally invasive oblique retroperitoneal approach to the infected focus. The patients underwent a standard lateral minimally invasive oblique retroperitoneal approach using direct lateral interbody fusion system. The PEEK cages were loaded with autologous bone graft. All the patients underwent posterior fixation with percutaneous pedicle screw instrumentation. Lumbar function was measured using Oswestry Disability Index, and pain was measured with visual analog scale. Fusion and subsidence were also recorded.The study included 5 female and 2 male patients. The median age was 58.9 years. The duration of follow-up was 31.8 ± 6.1 months (range: 24-47). All patients recovered from the infection without relapse within 24-month follow-up. Visual analog scale significantly declined from 7.57 ± 0.53 before surgery to 1.57 ± 0.53 at 12-month follow-up. Mean Oswestry Disability Index decreased from 72.14 ± 6.82 before surgery to 22.28 ± 2.13 after surgery. All patients had solid fusion at 2-year follow-up. Fusion occurred at 6 to 15 months (mean 9.8 months).The specific use of PEEK cages in lumbar polymicrobial spondylodiscitis suggests reliable outcome in terms of clinical and imaging outcomes in our limited cases.

Abstract
PURPOSE To access the feasibility and efficacy of percutaneous endoscopic debridement (PED) combined with percutaneous pedicle screw fixation (PPSF) in the treatment of lumbar pyogenic spondylodiscitis. METHODS Forty-five patients diagnosed as pyogenic spondylodiscitis underwent PPSF followed by PED. A drainage catheter was left in place for negative pressure drainage. Adequate systematic antibiotics were administered empirically or based on bacterial culture results. Clinical outcomes were assessed by physical examination, regular serologic testing, visual analog scale (VAS), Oswestry Disability Index (ODI), and imaging studies. RESULTS The mean operative time was 110.1 ± 21.2 minutes (range 80-165 minutes), with intra-operative blood loss 47.8 ± 21.0 ml (range 20-120 ml). All patients reported relief of back pain, able to sit up, and partially ambulate the next day. Causative pathogens were identified in 32 of 45 biopsy specimens, staphylococcal bacteria being the most prevalent strain. However, there were 13 patients with post-operative complications. During 6-12 months' follow-up, inflammatory markers showed infection controlled. VAS and ODI values were significantly improved. DISCUSSION Satisfactory clinical and functional outcomes were achieved in our patients post-operatively. It is recommended that PED plus PPSF can be another alternative for spondylodiscitis. CONCLUSION PED supplementing PPSF offers a valid option in treating spondylodiscitis, as it is minimally invasive, shortens hospital stay, and avoids prolonged bed rest with an optimistic outcome.

Abstract
Purpose: To observe the clinical curative effect of continuous epidural irrigation combined with posterior debridement and posterior lumbar inter-body fusion with instrumentation for the therapy of single-segment lumbar pyogenic spongdylodiscitis. Methods: From June 2010 to November 2013, surgical treatment was performed in 18 patients with pyogenic spondylodiscitis. The surgical indications were progressive biomechanical instability, epidural abscesses, deterioration of neurologic status, and intractable back pain. All these patients received posterior decompression with posterior instrumentation, debridement of infected tissue, and inter-body fusion. Visual Analogue Scale (VAS) scores were used to assess clinical outcomes. The neural function was evaluated by the Frankel grading system. Laboratory and radiologic results were recorded during clinical follow-up for at least one year. Results: The average follow-up period was 18 months after the operation. The VAS scores decreased from an average of 7.1 points before the procedure to 2.6 points after operation. The neurologic deficits of all the patients were recovered to Frankel grade E. All of the examined laboratory parameters were normalized gradually. Imaging-documented fusion was achieved in each patient, and no implants failure was noted. No patients showed any evidence of recurrence or persistence of infection. Conclusion: In carefully selected patients, single-segment lumbar pyogenic spondylodiscitis can be cured successfully with continuous epidural irrigation and drainage combined with posterior debridement and posterior lumbar inter-body fusion. Instrumentation could provide immediate stability and reconstruction of the spine column, and the presence of instrumentation did not result in any persistence or recurrence of infection. Continuous epidural irrigation and drainage is an effective method facilitating the elimination of residual infection.

Abstract
OBJECTIVE To investigate the effectiveness of allograft bones combined with poly-ether-ether-ketone (PEEK) cages or titanium mesh cages (TMCs) in the management of cervical spinal tuberculosis. METHODS A total of 16 patients with cervical spinal tuberculosis who underwent anterior debridement, reconstruction with allograft bones combined with PEEK cages or TMCs, and anterior plate fixation between 2013 and 2016 were retrospectively studied. Neck pain, neurologic status, operating time, intraoperative blood loss, cervical spine alignment, bony fusion, and self-reported clinical outcomes were reviewed. RESULTS Six patients underwent 1 level reconstruction using PEEK cages and 10 patients received TMCs reconstruction. Patients received a mean follow-up time of 45.9 ± 13.1 months. Neck pain was greatly relieved, as visual analog scale scores decreased from 4.6 ± 1.3 preoperatively to 0.7 ± 0.5 at the final follow-up (P < 0.05). Neurologic status was improved in all patients with neurologic deficits, with 9 patients improving by 1 grade and 1 patient by 2 grades. Kyphosis angle was corrected from 1.3 ± 12.0 degrees preoperatively to -5.4 ± 10.2 degrees postoperatively (P < 0.05) and remained at -3.6 ± 9.6 degrees at the final follow-up (P < 0.05). Bony fusion was achieved in all patients, with a mean time to the fusion of 3.8 ± 1.3 months. There was no implant failure or signs of cervical spinal tuberculosis recurrence. Excellent results, good results, and fair results were reported in 37.5%, 56.25%, and 6.25% of patients, respectively. CONCLUSIONS Allograft bone combined with PEEK cages and TMCs could bring about favorable clinical results in patients with cervical spinal tuberculosis. This method could be an alternative to autologous bone grafting method in the management of certain cases.

A unilateral less invasive posterolateral approach for disc debridement and titanium cage insertion supplemented by contralateral transfascial screw fixation for high-morbidity patients suffering from septic thoracolumbosacral spondylodiscitis. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2019; 29:1187-1197. [PMID: 30993521 DOI: 10.1007/s00590-019-02434-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/01/2018] [Accepted: 04/02/2019] [Indexed: 12/19/2022]
Abstract
PURPOSE This case series reports on the efficacy and safety of a less invasive posterolateral approach for septic thoracolumbosacral spondylodiscitis in high-morbidity patients. METHODS Twenty consecutive severe sick (ASA > III) patients (14 men and 6 women), with an average age of 64 ± 14 years, suffering from septic subacute and chronic thoracolumbosacral spondylodiscitis were selected to undergo a one-stage less invasive unilateral posterolateral disc space debridement, supplemented by an ipsilateral titanium cage implantation and pedicle screw fixation plus a contralateral transfascial pedicle screw fixation. RESULTS Two high-risk patients with severe comorbidities (ASA stage IV and V, respectively) died on days 1 and 8 postoperatively because of non-surgical complications such as massive lung embolism and acute myocardial infract, respectively. Three patients with incomplete paraplegia (ASIA C) preoperatively were improved after the surgery to ASIA D (two patients) and E (one patient), respectively, while there was no neurological deterioration in any patient postoperatively. From the 18 patients that survived, ten patients were available for the final follow-up 8.8 ± 2.7 years postoperatively. In two patients with spondylodiscitis caused by gram(-) bacteria, the posterior instrumentation was finally removed because of asymptomatic fistula emerging from posterior instrumentation solely, 15 and 19 months after surgery. The survivals at 2.5 and 10 years with revision as end point was 87.4% (95% CI 58.1-96.7); while in the "worst case scenario" the survivals at 2.5 and 10 years were: 66.7% (95% CI 40.4-83.4%); 47.7% (95% CI 23.2-68.8%) and 47.7% (95% CI 23.2-68.8%), respectively. CONCLUSIONS The less invasive posterolateral approach for disc debridement and titanium cage insertion seems to be an alternative surgery for severe sick adult immunosuppressed patients with septic thoracolumbosacral spondylodiscitis that cannot tolerate traditional open transthoracic, thoracolumbar, retroperitoneal or combined approaches. The study has been registered in the Public Registry ClinicalTrials.gov PRS with the ID: NCT03472131.

Abstract
BACKGROUND Spondylodiscitis is a chameleon among infectious diseases due to the lack of specific symptoms with which it is associated. It is nevertheless a serious infection, with 7% mortality of hospitalized patients, in large part because of delayed diagnosis. The aim of this study was to develop a diagnosis and course-of-disease index to optimize its treatment. MATERIAL AND METHODS Through analysis of 296 patients between January 1998 and December 2013, we developed a scoring system for spondylodiscitis, which we term SponDT (Spondylodiscitis Diagnosis and Treatment) based on three traits: (1) the inflammatory marker C-reactive protein (CRP) (mg/dl), (2) pain according to a numeric rating scale (NRS) and (3) magnetic resonance imaging (MRI), to monitor its progression following treatment. RESULTS The number of patients receiving treatment increased over the past 15 years of our study. We also found an increasing age of patients at the point of diagnosis across the study, with an average age of 67.7 years. In 34% of patients, spondylodiscitis developed spontaneously. Almost 70% of them did not receive treatment until the first diagnosis using SponDT. Following treatment against spondylodiscitis, pain intensity decreased from 6.0 to 3.1 NRS. The inflammatory markers also decreased (CRP from 119.2 to 46.7 mg/dl). Similarly, MRI revealed a regression in inflammation following treatment. By employing SponDT, patients were diagnosed and entered into treatment with a score of 5.6 (severe spondylodiscitis) and discharged with a score of 2.4 (light/healed spondylodiscitis). CONCLUSION SponDT can be used to support the diagnosis of spondylodiscitis, particularly in patients suffering from back pain and elevated levels of inflammation, and can be used during the course of treatment to optimize control of therapy. LEVEL OF EVIDENCE IIa-evidence from at least one well-designed controlled trial which is not randomized.

Abstract
BACKGROUND Lumbar pyogenic spondylodiscitis (LPS) is still a tangled problem in its management, especially with increasing rates of cases who underwent different spinal procedures and in patients with chronic medical disease. One-stage posterior direct transforminal lumbar thorough debridement of septic lesion, decompression, and spondylodesis (TLTDDS) are the main goals in treatment of complicated LPS without additional morbidity of anterior surgery. This is a retrospective assessment of the clinical, laboratory, functional, and radiologic outcomes in 25 patients with LPS who underwent the TLTDDS procedure. METHODS Twenty-nine patients with complicated LPS were treated surgically by TLTDDS surgery from January 2014 to August 2017. Complete records of 25 patients were available for evaluation. All patients were examined clinically for back or leg pain using a visual analog scale (VAS) and neurological assessment by the American Spine Injury Association. Perioperative outcome and complications were documented. All patients were serially followed up between 12 and 32 months as regard pain (VAS), functional status by Kirkaldy Willis criteria, and Oswestry disability index, laboratory, and radiologic outcomes (angle of segmental kyphosis, lumbar lordosis correction, and fusion criteria). RESULTS Definitive solid bony fusion was seen between 6 and 14 months, except in 3 cases, which showed probable fusion. There was significant improvement in VAS, American Spine Injury Association index, laboratory investigations, and Oswestry disability index. One patient (5%) had transient neurological deficit, which resolved completely within 2 months. CONCLUSIONS TLTDDS surgery is an effective procedure in the treatment of symptomatic LPS and allows abscess evacuation with adequate neural decompression, segmental kyphosis correction, and functional improvement.

Abstract
OBJECTIVESpontaneous spondylodiscitis remains uncommon but is a serious complication of the vertebral column. Risk factors include diabetes, hemodialysis, intravenous drug abuse, and chronic steroid use, and pain is the most common presenting symptom. This study aims to review the literature and report on the incidence, management, and clinical outcome of spontaneous spondylodiscitis in 44 patients.METHODSThis is a prospective study including 44 patients with spontaneous spondylodiscitis managed in the neurosurgery department of Cairo University Hospitals during the period between January 2012 and October 2017. All patients had a full clinical assessment, laboratory tests, radiological studies in the form of MRI with and without contrast, and a postoperative follow-up of up to 12 months.RESULTSTwelve cases underwent conservative treatment in the form of complete bed rest, intravenous antibiotics, and a spinal brace. Ten cases underwent surgical intervention in the form of laminectomy, debridement, and open biopsy. Twenty-two cases underwent laminectomy and surgical stabilization with fusion. There were 15 cases of tuberculous spondylodiscitis, 6 cases of brucellosis, 6 cases of pyogenic infection, and 17 cases in which no organism could be detected.CONCLUSIONSOnce the primary diagnosis is confirmed, early and adequately prolonged antibiotic therapy is recommended for spontaneous spondylodiscitis. Some cases can be successfully treated with conservative treatment alone, whereas surgery may be needed in other cases such as severe destruction of endplates, spinal abscess formation, mechanical instability, neurological deficits, and severe pain that have failed to respond to conservative treatment.

Abstract
OBJECTIVE The aim of this study was to compare the clinical, radiologic, and functional outcomes of a 1-stage posterior treatment versus a 2-stage posterior-anterior treatment in patients with pyogenic thoracic spondylodiscitis. METHODS A 1-stage posterior debridement, stabilization, and fusion with titanium-coated polyetheretherketone (PEEK) or mesh cage through a dorsolateral approach was performed in group A. A 2-stage procedure with initial posterior stabilization and debridement and second-stage fusion with a PEEK cage or mesh cage was performed with an anterior approach in group B. Clinical outcomes included Oswestry Low Back Pain Disability Questionnaire and visual analog scale score. Radiologic outcomes included fusion rate and kyphotic angle correction. Secondary variables included pathogens, complications, blood loss, and operative time. RESULTS One-level spondylodiscitis was treated surgically in the thoracic spine of 47 patients: 25 patients in group A and 22 patients in group B. The most frequent segment was T12-L1 (27%). There was a significantly longer operative time and greater blood loss (P > 0.001) in group B. At last follow-up, sagittal profile reconstruction was significantly better (P > 0.05) in group B. Both groups showed similar radiologic results with fusion in 92% of cases. Improved clinical outcomes, pain, and quality of life were achieved in both groups with no significant differences between the 2 groups. CONCLUSIONS Better reconstruction of the sagittal profile was achieved in the posterior-anterior-treated group, but this did not affect the clinical outcome. No significant differences were found in the clinical and functional outcomes between the 2 groups. Posterior-anterior combined treatment should be considered in cases of large anterior defects if a posterior reconstruction is inadequate.

Minimally invasive spine surgery in lumbar spondylodiscitis: a retrospective single-center analysis of 67 cases. 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 2017; 26:3141-3146. [PMID: 28608178 DOI: 10.1007/s00586-017-5180-x] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2017] [Revised: 05/05/2017] [Accepted: 06/06/2017] [Indexed: 12/19/2022]
Abstract
BACKGROUND Minimally invasive surgical techniques have been developed to minimize tissue damage, reduce narcotic requirements, decrease blood loss, and, therefore, potentially avoid prolonged immobilization. Thus, the purpose of the present retrospective study was to assess the safety and efficacy of a minimally invasive posterior approach with transforaminal lumbar interbody debridement and fusion plus pedicle screw fixation in lumbar spondylodiscitis in comparison to an open surgical approach. Furthermore, treatment decisions based on the patient´s preoperative condition were analyzed. METHODS 67 patients with lumbar spondylodiscitis treated at our department were included in this retrospective analysis. The patients were categorized into two groups based on the surgical procedure: group (MIS) minimally invasive lumbar spinal fusion (n = 19); group (OPEN) open lumbar spinal fusion (n = 48). Evaluation included radiological parameters on magnetic resonance imaging (MRI), laboratory values, and clinical outcome. RESULTS Preoperative MRI showed higher rates of paraspinal abscess (35.5 vs. 5.6%; p = 0.016) and multilocular location in the OPEN group (20 vs. 0%, p = 0.014). Overall pain at discharge was less in the MIS group: NRS 2.4 ± 1 vs. NRS 1.6 ± 1 (p = 0.036). The duration of hospital stay was longer in the OPEN than the MIS group (19.1 ± 12 days vs. 13.7 ± 5 days, p = 0.018). CONCLUSION The open technique is effective in all varieties of spondylodiscitis inclusive in epidural abscess formation. MIS can be applied safely and effectively as well in selected cases, even with epidural abscess.

Safety and efficacy of polyetheretherketone (PEEK) cages in combination with posterior pedicel screw fixation in pyogenic spinal infection. Acta Neurochir (Wien) 2016; 158:1851-7. [PMID: 27510825 DOI: 10.1007/s00701-016-2924-z] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2016] [Accepted: 08/01/2016] [Indexed: 12/19/2022]
Abstract
BACKGROUND To date, there is growing consensus that PEEK material may be used for interbody fusion in spinal infections. Data supporting that claim are however restricted to a few very small clinical series. The aim of this study is to evaluate the outcome of surgical treatment of pyogenic spinal infections with PEEK cages in combination with posterior pedicel screw fixation. METHODS Between 2006 and 2013, a total of 211 patients suffering from spondylodiscitis underwent surgical debridement and instrumentation. There were 52 cases where PEEK cages were used. Laboratory and physical examinations were assessed at a 3-month follow-up. Last follow-up was performed with at a minimum of 12 months after surgery via a telephone interview. RESULTS Mean age at presentation was 67 years, with 19 (37 %) male patients and 33 (63 %) female. Distribution of the infection was lumbar in 29 (56 %%), thoracic in 3 (6 %) and cervical in 11 (21 %) cases. Nine patients (17 %) had concomitant non-contiguous spondylodiscitis. Epidural abscess was found in 17 patients (33 %); 48 (92 %%) had pain; neurological deficits were found in 20 patients (38 %). All patients in this series underwent surgical debridement with instrumentation of the spine. Postoperative intravenous antibiotics were administered for 15.4 ± 6.8 days followed by 2.9 ± 0.5 months of oral antibiotics. Complete resolution of the infection was achieved in all cases. Of the 28 patients with neurological deficits, 6 had full recovery and 10 had improved incompletely after surgery. One patient suffered from a pulmonary embolism postoperatively. There were no mortalities. CONCLUSIONS Use of PEEK cages for interbody fusion is feasible and safe in patients suffering from a pyogenic spinal infection.
