Abstract
BACKGROUND Surgical treatment of vertebral osteomyelitis, discitis, and epidural abscesses is indicated in the setting of failure of antibiotic therapy, neurological deficits, epidural abscess, or spinal instability/deformity. Historically, surgical treatment mandated aggressive debridement and spinal stabilization. However, there is growing evidence that direct debridement may not be necessary and may contribute to morbidity. The purpose of this study was to evaluate the efficacy of posterior instrumentation without debridement in treating spinal infections. METHODS A retrospective medical record review was performed to identify patients treated with posterior instrumentation for spontaneous spinal infections. Success of treatment was determined based on postoperative ambulatory status, surgical complications, and need for revision surgery. RESULTS Twenty-seven patients treated with posterior-only long-segmented rigid fixation without formal debridement of infected material were included. The most common indications for surgical intervention included spinal instability (67%), neurologic compromise (67%), and failure of prolonged antibiotic treatment (63%). There were no recurrent deep infections in 21 of 22 patients who had long-term follow-up. Four patients required revision surgery, and 3 additional patients requested elective hardware removal. Postoperatively, 70% were ambulatory with no assistive devices postoperatively. CONCLUSIONS Vertebral osteomyelitis/discitis are challenging medical problems. Single-stage long-segment fusion without formal debridement combined with antibiotics is effective in the management of spontaneous spinal infections. CLINICAL RELEVANCE The present study suggests that acute instrumentation without anterior debridement is associated with a resolution of infection and improvements in neurologic deficits in patient with spontaneous spine infections.

Conservative versus early surgical treatment in the management of pyogenic spondylodiscitis: a systematic review and meta-analysis. Sci Rep 2023; 13:15647. [PMID: 37730826 PMCID: PMC10511402 DOI: 10.1038/s41598-023-41381-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 08/25/2023] [Indexed: 09/22/2023] Open
Abstract
Spondylodiscitis is the commonest spine infection, and pyogenic spondylodiscitis is the most common subtype. Whilst antibiotic therapy is the mainstay of treatment, some advocate that early surgery can improve mortality, relapse rates, and length of stay. Given that the condition carries a high mortality rate of up to 20%, the most effective treatment must be identified. We aimed to compare the mortality, relapse rate, and length of hospital stay of conservative versus early surgical treatment of pyogenic spondylodiscitis. All major databases were searched for original studies, which were evaluated using a qualitative synthesis, meta-analyses, influence, and regression analyses. The meta-analysis, with an overall pooled sample size of 10,954 patients from 21 studies, found that the pooled mortality among the early surgery patient subgroup was 8% versus 13% for patients treated conservatively. The mean proportion of relapse/failure among the early surgery subgroup was 15% versus 21% for the conservative treatment subgroup. Further, it concluded that early surgical treatment, when compared to conservative management, is associated with a 40% and 39% risk reduction in relapse/failure rate and mortality rate, respectively, and a 7.75 days per patient reduction in length of hospital stay (p < 0.01). The meta-analysis demonstrated that early surgical intervention consistently significantly outperforms conservative management in relapse/failure and mortality rates, and length of stay, in patients with pyogenic spondylodiscitis.

Risk factors for surgical intervention in patients with primary spinal infection on initial presentation. J Neurosurg Spine 2022; 37:283-291. [PMID: 35120318 DOI: 10.3171/2021.12.spine21811] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Accepted: 12/09/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Treatment of primary spinal infection includes medical management with or without surgical intervention. The objective of this study was to identify risk factors for the eventual need for surgery in patients with primary spinal infection on initial presentation. METHODS From January 2010 to July 2019, 275 patients presented with primary spinal infection. Demographic, infectious, imaging, laboratory, treatment, and outcome data were retrospectively reviewed and collected. Thirty-three patients were excluded due to insufficient follow-up (≤ 90 days) or death prior to surgery. RESULTS The mean age of the 242 patients was 58.8 ± 13.6 years. The majority of the patients were male (n = 130, 53.7%), White (n = 150, 62.0%), and never smokers (n = 132, 54.5%). Fifty-four patients (22.3%) were intravenous drug users. One hundred fifty-four patients (63.6%) ultimately required surgery while 88 (36.4%) never needed surgery during the duration of follow-up. There was no significant difference in age, gender, race, BMI, or comorbidities between the surgery and no-surgery groups. On univariate analysis, the presence of an epidural abscess (55.7% in the no-surgery group vs 82.5% in the surgery group, p < 0.0001), the median spinal levels involved (2 [interquartile range (IQR) 2-3] in the no-surgery group vs 3 [IQR 2-5] in the surgery group, p < 0.0001), and active bacteremia (20.5% in the no-surgery vs 35.1% in the surgery group, p = 0.02) were significantly different. The cultured organism and initial laboratory values (erythrocyte sedimentation rate, C-reactive protein, white blood cell count, creatinine, and albumin) were not significantly different between the groups. On multivariable analysis, the final model included epidural abscess, cervical or thoracic spine involvement, and number of involved levels. After adjusting for other variables, epidural abscess (odds ratio [OR] 3.04, 95% confidence interval [CI] 1.64-5.63), cervical or thoracic spine involvement (OR 2.03, 95% CI 1.15-3.61), and increasing number of involved levels (OR 1.16, 95% CI 1.01-1.35) were associated with greater odds of surgery. Fifty-two surgical patients (33.8%) underwent decompression alone while 102 (66.2%) underwent decompression with fusion. Of those who underwent decompression alone, 2 (3.8%) of 52 required subsequent fusion due to kyphosis. No patient required hardware removal due to persistent infection. CONCLUSIONS At time of initial presentation of primary spinal infection, the presence of epidural abscess, cervical or thoracic spine involvement, as well as an increasing number of involved spinal levels were potential risk factors for the eventual need for surgery in this study. Additional studies are needed to assess for risk factors for surgery and antibiotic treatment failure.

The effect of instrumentation staging on patient outcomes in pyogenic vertebral osteomyelitis: A systematic review. NORTH AMERICAN SPINE SOCIETY JOURNAL (NASSJ) 2021; 8:100083. [PMID: 35141648 PMCID: PMC8819946 DOI: 10.1016/j.xnsj.2021.100083] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 09/27/2021] [Accepted: 10/01/2021] [Indexed: 11/22/2022]
Abstract
Background Pyogenic vertebral osteomyelitis is a bacterial infection of the vertebral body that is often treatable with antibiotics, but some cases require additional surgical debridement of the infected tissue. Instrumentation is often utilized for stabilization of the spine as part of the surgical treatment, but controversy remains over the relative risks and benefits of acute instrumentation performed simultaneously with debridement versus delayed instrumentation performed days or weeks after debridement. The purpose of this review was to investigate the relative effects of acute and delayed instrumentation in treatment for pyogenic vertebral osteomyelitis on patient outcomes. Methods A PRISMA-compliant systematic literature review was conducted to identify studies published between January 1, 1997 and July 23, 2021. Studies were screened for pre-defined inclusion and exclusion criteria. The primary outcome of interest was reinfection. Other outcomes of interest included neurological status, pain, progression of kyphosis, fusion, hardware failure, length of hospitalization, and mortality at two years. Due to the limited multi-armed studies available that distinguish between patients with acute and delayed instrumentation, inferential statistics were not performed, and data are expressed as descriptive statistics. Results A total of 9 studies met our inclusion criteria, comprising 299 patients, including 113 (37.8%) with surgical treatment without fixation, 138 (46.2%) with acute instrumentation, and 48 (16.1%) with delayed instrumentation. Reinfection rates were 60.0% (15/25) for surgical treatment without fixation, 28.6% (2/7) for the acute instrumentation, and 14.3% (1/7) for the delayed instrumentation group. Pain was present after surgery in 52.0% (13/25) of the surgical treatment without fixation group, 14.3% (1/7) of the acute instrumentation group, and 0% (0/7) of the delayed instrumentation group. Conclusions No major differences in patient outcomes were apparent between acute and delayed instrumentation groups. Further research is needed to determine whether instrumentation staging has a significant impact on patient outcomes.
