Surgical management of ventrally located cervical epidural abscess: A comparative analysis between patients aged 18-64 years and ≥65 years.

Background: We aimed to compare the clinical course of patients aged 18-65 years and ≥65years who underwent anterior cervical discectomy and fusion (ACDF) or corpectomy for ventrally located CSEA. Methods: Clinical and imaging data were retrospectively collected from the institutional database between September 2005 and December 2021. Results: A total of 35 and 26 patients aged 18-64 and ≥ 65 years, respectively who were diagnosed with ventrally located CSEA were included. The overall mean age was 63.9 ± 3.2 years, with a predominance of the male sex (n = 43/61, 70.5%). Patients aged ≥65 years presented with significantly higher rates of comorbidities (10.3 ± 2.8), as indicated by the CCI, than their younger counterparts (18-64 years: 6.2 ± 2.6; p < 0.001). No differences in the surgical approach or characteristics were observed among the groups. Notably, patients aged ≥65 years had a significantly longer intensive care unit as well as overall hospital stay. In-hospital and 90-day mortality were similar across both groups. Following both types of surgery, a significant improvement was observed in the blood infection parameters and neurological status at discharge compared with the baseline measurements. Older age, higher rates of comorbidities, and higher grades of disability were significant predictors for mortality. Conclusions: Emergency surgical evacuation should be undertaken for CSEA in the presence of acute neurological deterioration regardless of the age. Factors, such as age, comorbidities, and neurological status on admission appear to be important predictors of disease outcomes. However, the risk profile of younger patients should not be underestimated.

Anterior cervical discectomy fusion versus posterior decompression and fusion in octogenarians with cervical myelopathy: Clinical outcomes and complications with a 3-year follow-up.

Introduction: Cervical stenosis and concurrent Cervical Spondylotic Myelopathy (CSM) are prevalent in the elderly. Treatment options include Anterior Cervical Discectomy Fusion (ACDF) and Posterior Decompression and Fusion (PDF). Research question: This study aims to compare clinical outcomes and complications between ACDF and PDF in patients aged 80 and above. Material and methods: Data from electronic medical records between 2005 and 2021 at a single institution were analyzed. Logistic and linear regression analyses were performed to explore risk factors and the relationship between comorbidities and neurological conditions. Results: 21 patients with ACDF and 26 with PDF were studied over 16 years. PDF patients had more operated levels, higher blood loss, and longer hospital stays, but mortality rates and mJOA improvements were similar in both groups. The presence of comorbidities was a unique risk factor for postoperative complications. Discussion and conclusion: ACDF and PDF led to neurological improvements in elderly CSM patients. However, the decision of surgical procedure should carefully consider the potential for postoperative complications, particularly in patients with comorbidities.

Morbidity and mortality related to type II odontoid fractures in octogenarians undergoing surgery: a retrospective study with 5 year follow up.

Introduction: The prevalence of trauma is increasing in the geriatric population. The optimal therapy for type II odontoid fractures in the elderly is controversial. This study aims to assess the morbidity and mortality associated with odontoid fractures in octogenarians undergoing C1/C2 posterior screw fixation and describe the perioperative and post-operative complications and risk factors associated with mortality. Materials and methods: Electronic medical records from a single institution pertaining to the period between September 2005 and December 2020 were retrieved. Data on patient demographics, neurological conditions, surgical characteristics, complications, hospital course, and 90-day mortality were collected. Results: Over a 16-year period, 60 patients aged ≥80 years diagnosed with type II odontoid fractures were enrolled in the study. The mean age was 85.0 ± 1.9 years. The mean Charlson Comorbidity Index (CCI) was >6 indicating a poor baseline reserve (8.5 ± 1.9), while cardiovascular diseases were the most prevalent among comorbidities. The mean surgical duration was 217.5 ± 65.9 min, with a mean blood loss of 725.5 ± 275.7 mL. The in-hospital was 5-0% and the 90-day mortality rates increased at 10.0%. No revision surgery was needed in any of the cases. Intraoperative and post-operative X-ray and computed tomography (CT) imaging revealed correct screw placement. Proper alignment of the atlantoaxial spine and fusion could be achieved in all cases. The unique risk factors for mortality included the presence of comorbidities and the occurrence of post-operative complications. Conclusion: The complication and mortality rates associated with odontoid fractures in octogenarians are relatively high. However, the therapeutic goals in this population also include bone union and preservation of neurological status. Despite the often-high comorbidity rate, we still recommend that surgery should be considered in patients over 80 years. However, it is necessary to evaluate several approaches when treating such frail patients.

Emergency Posterior Decompression for Metastatic Spine Tumors in Octogenarians: Clinical Course and Prognostic Factors for Functional Outcomes.

BACKGROUND: This study aimed to describe the clinical outcome of metastatic epidural spinal cord compression in octogenarians with an acute onset of neurological illness who undergo laminectomy, further assess morbidity and mortality rates, and determine potential risk factors for a nonambulatory outcome. METHODS: This retrospective review of electronic medical records at a single institution was conducted between September 2005 and December 2020. Patient demographics, surgical characteristics, complications, hospital course, and 90-day mortality were collected. RESULTS: Thirty-four patients aged 80 years and older who posterior decompression via laminectomy were enrolled in the present study. The mean Charlson Comorbidity Index was >6 (9.2 ± 2.1). The thoracic spine was the most common site of metastasis. A potentially unstable spine, determined using the Spinal Instability Neoplastic Score, was identified in 79.4% of the cases. Preoperatively, the neurological condition and functional status exhibited a notable decline (mean Motor Score of the American Spinal Injury Association grading system, 78.2 ± 16.4; mean Karnofsky Performance Index, 47.8 ± 19.5). The Motor Score of the American Spinal Injury Association grading system and Karnofsky Performance Index scores improved significantly after surgery. Motor weakness and comorbidities were unique risk factors for the loss of ambulation. CONCLUSIONS: Emergent decompressive laminectomy in patients with acute onset of neurological decline and potentially unstable spines improved functional outcome at discharge. Age should not be a determinant of whether to perform surgery; surgery should be performed in older patients when indicated.

Perioperative morbidity and mortality in octogenarians sustaining traumatic osteoporotic type 4 and 5 thoracolumbar and lumbar fractures: a retrospective study with 3 years follow-up.

PURPOSE: This study aimed to guide the more efficient management of type 4 and 5 thoracolumbar or lumbar osteoporotic fractures (OF) in patients aged 80 years and older with an acute onset of neurological decline. This aim was achieved by assessing the clinical course and morbidity and mortality rates and identifying potential risk factors for patient mortality METHODS: Electronic medical records were retrieved from a single institution pertaining to the period between September 2005 and December 2020. Data on patient demographics, neurological conditions, surgical characteristics, complications, hospital course, and 90-day mortality were also collected. RESULTS: Over a 16-year period, 35 patients aged ≥80 years diagnosed with thoracolumbar and lumbar OF were enrolled in the study. The mean Charlson comorbidity index (CCI) was >6, indicating a poor baseline reserve (9.4 ± 1.9), while cardiovascular diseases were the most prevalent among comorbidities. The mean surgical duration was 231.6 ± 89.3 min, with a mean blood loss of 694.4± 200.3 mL. The in-hospital was 8.6% and 90-day mortality rates at 11.4%. Two patients underwent revision surgery for deep wound infection. Intraoperative and postoperative radiography and computed tomography (CT) imaging revealed correct screw placement. Proper alignment of the thoracolumbar spine was achieved in all the patients. Unique risk factors for mortality included the presence of comorbidities and the occurrence of postoperative complications. CONCLUSIONS: Emergent instrumentation in patients with acute onset of neurological decline and potentially unstable spines due to thoracolumbar and lumbar OF improved functional outcomes at discharge. Age should not be a determinant of whether to perform surgery.

Mortality, complication risks, and clinical outcomes after surgical treatment of spinal epidural abscess: a comparative analysis of patients aged 18-64 years, 65-79 years, and ≥ 80 years, with a 3-year follow-up.

Spinal epidural abscess (SEA) with pyogenic vertebral osteomyelitis (PVO) is a rare illness with a steadily increasing incidence. However, comparative analyses of young and older patients with SEA are lacking. We aimed to compare the clinical course of patients aged 18-64 years, 65-79 years, and ≥ 80 years undergoing surgery for SEA. Clinical and imaging data were retrospectively collected from the institutional database between September 2005 and December 2021. Ninety-nine patients aged 18-64 years, 45 patients aged 65-79 years, and 32 patients ≥ 80 years were enrolled. Patients ≥ 80 years presented with a poorer baseline history (9.2 ± 2.4), as indicated by the CCI, than their younger counterparts (18-74 years: 4.8 ± 1.6;6.5 ± 2.5; p < 0.001). Patients aged 65-79 years and 80 years had a significantly longer length of stay. In-hospital mortality was significantly higher in those aged ≥ 80 years compared to their younger counterparts (≥ 80 years, n = 3, 9.4% vs. 18-64 years, n = 0, 0.0%; 65-79 years, n = 0, 0.0%; p < 0.001), while no differences in 90-day mortality or 30-day readmission were observed. After surgery, a significant decrease in C-reactive protein levels and leukocytes and amelioration of motor scores were observed in all the groups. Of note, older age (> 65 years), presence of comorbidities, and poor preoperative neurological condition were significant predictors of mortality. Surgical management led to significant improvements in laboratory and clinical parameters in all age groups. However, older patients are prone to multiple risks, requiring meticulous evaluation before surgery. Nevertheless, the risk profile of younger patients should not be underestimated. The study has the limitations of a retrospective design and small sample size. Larger randomized studies are warranted to establish the guidelines for the optimal management of patients from every age group and to identify the patients who can benefit from solely conservative management.

Anterior cervical discectomy and fusion with plate versus posterior screw fixation after traumatic subaxial fractures in octogenarians: complications and outcomes with a 2-year follow-up.

INTRODUCTION: Surgical intervention for management of spinal instability after traumatic subaxial fractures in octogenarians requires a clear consensus on optimal treatments. This study aimed to provide a guide for more efficient management through comparison and assessment of clinical outcomes and complications of anterior cervical discectomy and fusion with plate (pACDF) and posterior decompression fusion (PDF) instrumentation alone in patients aged 80 years. METHODS: A single institution retrospective review of electronic medical records was undertaken between September 2005 and December 2021. Comorbidities were assessed using the age-adjusted Charlson comorbidity index (CCI). Logistic regression was used to identify potential risk factors for ACDF complications. RESULTS: The rate of comorbidities were similarly high between the pACDF (n=13) and PDF (n=15) groups (pACDF: 8.7 ± 2.4 points vs. 8.5 ± 2.3 points; p=0.555). Patients in the PDF group had significantly longer surgical duration (235 ± 58.4 min vs. 182.5 ± 32.1 min; p<0.001) and significantly higher volumes of intraoperative blood loss (661.5 ± 100.1 mL vs. 487.5 ± 92.1 mL; p<0.001). The in-hospital mortality was 7.7% for the pACDF group and 6.7% for the PDF group. On day 90, the mortality rate increased in both groups from baseline (pACDF: 15.4% vs. PDF: 13.3; p>0.05). Motor scores (MS) improved significantly after surgery in both groups (pACDF: preOP MS: 75.3 ± 11.1 vs. postOP MS: 82.4 ± 10.1; p<0.05; PDF: preOP MS: 80.7 ± 16.7 vs. postOP MS: 89.5 ± 12.1; p<0.05). Statistically significant predictors for postoperative complications included longer operative times (odds ratio 1.2, 95% confidence interval 1.1-2.1; p=0.005) and larger volume of blood loss (odds ratio 1.5, 95% confidence interval 1.2-2.2; p=0.003). CONCLUSIONS: Both pACDF and PDF can be considered safe treatment strategies for octogenarians with a poor baseline profile and subaxial fractures as they lead to patients substantial neurological improvements, and they are accompanied with low morbidity and mortality rates. Operation duration and intraoperative blood loss should be minimized to increase the degree of neurological recovery in octogenarian patients.

ACDF versus corpectomy in octogenarians with cervical epidural abscess: early complications and outcomes with 2 years of follow-up.

PURPOSE: Cervical spinal epidural abscess (CSEA) is a rare condition, manifesting as rapid neurological deterioration and leading to early neurological deficits. Its management remains challenging, especially in patients older than 80 years. Therefore, we aimed to compare the clinical course and determine morbidity and mortality rates after anterior cervical discectomy and fusion (ACDF) versus corpectomy in octogenarians with ventrally located CSEA at two levels. METHODS: In this single-center retrospective review, we obtained the following from electronic medical records between September 2005 and December 2021: patient demographics, surgical characteristics, complications, hospital clinical course, and 90-day mortality rate. Comorbidities were assessed using the age-adjusted Charlson comorbidity index (CCI). RESULTS: Over 16 years, 15 patients underwent ACDF, and 16 patients underwent corpectomy with plate fixation. Between the two groups, patients who underwent corpectomy had a significantly poorer baseline reserve (9.0 ± 2.6 vs. 10.8 ± 2.7; p = 0.004) and had a longer hospitalization period (16.4 ± 13.1 vs. 10.0 ± 5.3 days; p = 0.004) since corpectomy lasted significantly longer (229.6 ± 74.9 min vs. 123.9 ± 47.5 min; p < 0.001). Higher in-hospital and 90-day mortality and readmission rates were observed in the corpectomy group, but the difference was not statistically significant. Both surgeries significantly improved blood infection parameters and neurological status at discharge. Revision surgery due to pseudoarthrosis was required in two patients after corpectomy. CONCLUSIONS: We showed that both ACDF and corpectomy for ventrally located CSEA can be considered as safe treatment strategies for patients aged 80 years and above. However, the surgical approach should be carefully weighed and discussed with the patients and their relatives.

Intradural Extramedullary Pyogenic Abscess: Incidence, Management, and Clinical Outcomes in 45 Patients With a Mean Follow Up of 2 Years.

STUDY DESIGN: Retrospective review. OBJECTIVES: Spinal intradural extramedullary abscess (SIEA) is a rare disease with an unknown incidence. In this study, we systematically described the clinical course of SIEA in a large cohort with acute onset of neurological illness, assessed the morbidity and mortality rates, and determined the potential risk factors for mortality. METHODS: Electronic medical records of patients diagnosed with SIEA at a single institution for the period between September 2005 and December 2020 were retrieved. RESULTS: Over a period of 15 years, 881 patients with spinal infections were treated either conservatively or surgically at our center, of whom 45 patients (45/881, 5.1%) had SIEA. The overall mean age was 69.6 ± 5.6 years of patients diagnosed with SIEA and all of them underwent posterior decompression via laminectomy. The mean Charlson Comorbidity Index (CCI) was 6.9 ± 2.5, indicating a poor baseline reserve. Progressive neurological decline was observed in all patients (mean motor score, 88.6 ± 9.7). The in-hospital rate and 90-day mortality were 4.4% and 10%, respectively. Mortality was not surgery related. Most importantly, the patients' motor deficits and blood infection parameters significantly improved after surgery. Risk factors for mortality were increased age, comorbidities as measured by CCI, and preoperative motor weakness (MS). CONCLUSIONS: Immediate surgical decompression via laminectomy, with antiseptic irrigation and drainage of the subdural space, followed by antibiotic therapy, appears to be the key to ensuring beneficial clinical outcomes to treatment of rare diseases such as SIEA.

Emergency surgical decompression for spontaneous spinal epidural hematoma in octogenarians: risk factors, clinical outcomes, and complications.

PURPOSE: Spontaneous spinal epidural hematoma (SSEH) is a rare but disabling disease. Although several cases have been reported in the literature, their treatment remains unclear, especially in patients with advanced age. We, therefore, aimed to describe the clinical outcomes of cervical SSEH in octogenarians with an acute onset of neurological illness undergoing laminectomy. METHODS: Electronic medical records from a single institution between September 2005 and December 2020 were retrieved. Data on patient demographics, neurological conditions, functional status, surgical characteristics, complications, hospital course, and 90-day mortality were also collected. RESULTS: Twenty-two patients aged ≥ 80 years with SSEH undergoing laminectomy were enrolled in this study. The mean Charlson comorbidity index was 9.1 ± 2.0, indicating a poor baseline reserve. Ten individuals (45.5%) were taking anticoagulant agents with a pathologic partial thromboplastin time (PTT) of 46.5 ± 3.4 s. Progressive neurological decline, as defined by the motor score (MS), was observed on admission (63.8 ± 14.0). The in-hospital and 90-day mortality were 4.5% and 9.1%, respectively. Notably, the MS (93.6 ± 8.3) improved significantly after surgery (p < 0.05). Revision surgery was necessary in 5 cases due to recurrent hematoma. Anticoagulant agents and pathological PTT are significant risk factors for its occurrence. Motor weakness and comorbidities were unique risk factors for loss of ambulation. CONCLUSIONS: Laminectomy and evacuation of the hematoma in octogenarians with progressive neurological decline induce clinical benefits. Emergent surgery seems to be the "state of the art" treatment for SSEH. However, potential complications associated with adverse prognostic factors, such as the use of anticoagulants, should be considered.

Spinal Meningioma Surgery in Octogenarians: Functional Outcomes and Complications over a 2-Year Follow-Up Period.

Background and Objectives: Population aging in industrial nations has led to an increased prevalence of benign spinal tumors, such as spinal meningiomas (SMs), in the elderly. The leading symptom of SM is local pain, and the diagnosis is confirmed after acute neurological decline. However, little is known about the optimal treatment for this frail patient group. Therefore, this study sought to assess the clinical outcome, morbidity, and mortality of octogenarians with SMs and progressive neurological decline undergoing surgery and to determine potential risk factors for complications. Materials and Methods: Electronic medical records dated between September 2005 and December 2020 from a single institution were retrieved. Data on patient demographics, neurological conditions, functional status, degree of disability, surgical characteristics, complications, hospital course, and 90-day mortality were collected. Results: Thirty patients aged ≥80 years who were diagnosed with SMs underwent posterior decompression via laminectomy and microsurgical tumor resection. The patients presented with a poor baseline history (mean CCI 8.9 ± 1.6 points). Almost all SMs were located in the thoracic spine (n = 25; 83.3%). Progressive preoperative neurological decline was observed in 21/30 (n = 21; 70%) patients with McCormick Scores (mMCS) ≥3, and their mean motor score (MS) was 85.9 ± 12.3. in the in-hospital and 90-day mortality rates were 6.7% and 10.0%, respectively. The MS (93.6 ± 8.3) and mMCS (1.8 ± 0.9) improved significantly postoperatively (p < 0.05). The unique risk factor for complications was the severity of comorbidities. Conclusions: Decompressive laminectomy and tumor removal in octogenarians with progressive neurological decline improved patient functional outcomes at discharge. Surgery seems to be the "state of the art" treatment for symptomatic SMs in elderly patients, even those with poor preoperative clinical and neurologic conditions, whenever there is an acceptable risk from an anesthesiological point of view.

Lumbar Decompression versus Decompression and Fusion in Octogenarians: Complications and Clinical Course With 3-Year Follow-Up.

STUDY DESIGN: Retrospective review. OBJECTIVES: This study aimed to assess and compare the clinical course and complications between surgical decompression and decompression with fusion in lumbar spine patients aged ≥80 years. METHODS: A retrospective review of electronic medical records at a single institution was conducted between September 2005 and December 2021. Logistic regression was used to identify potential risk factors for the occurrence of complications. RESULTS: Over a 16-year period, 327 patients were allocated to the decompression only group and 89 patients were allocated to the decompression and instrumented fusion group. The study had a mean follow-up duration of 36.7 ± 12.4 months. When assessing the CCI, patients of the instrumentation group had fewer comorbidities (8.9 ± .5 points vs 6.2 ± 1.5 points; P < .001), significantly longer surgical duration (290 ± 106 minutes vs 145 ±50.2 minutes; P < .001), significantly higher volume of intraoperative blood loss (791 ± 319.3 ml vs 336.1 ± 150.8 ml; P < .001), more frequent intraoperative blood transfusion (7 ± 2.1% vs 16± 18.0%; P < .001), and extended stays in the intensive care unit and hospitalization rates. Logistic regression analysis revealed that surgical duration and extent of surgery were unique risk factors for the occurrence of complications. CONCLUSIONS: Lumbar decompression and additional fusion in octogenarians are considerable treatment techniques; albeit associated with increased complication risks. Prolonged operative time and extent of surgery are critical confounding factors associated with higher rates of postoperative complications. Surgery should only be performed after careful outweighing of potential benefits and risks.

Surgical Management of Spinal Epidural Abscess in Elderly Patients: A Comparative Analysis Between Patients 65-79 Years and ≥80 Years with 3-Year Follow-Up.

BACKGROUND: Recently, the incidence of pyogenic vertebral osteomyelitis with spinal epidural abscess (SEA) has increased. However, the most appropriate surgical management remains debatable, especially for older patients. This study aimed to compare the clinical course in older patients aged between 65 and 79 years and those 80 years or older undergoing surgery for SEA. METHODS: Data on patient demographics, surgical characteristics, complications, hospital clinical course, and 90-day mortality of patients diagnosed with pyogenic vertebral osteomyelitis and SEA between September 2005 and December 2021 were collected. Comorbidities were assessed using the age-adjusted Charlson comorbidity index. RESULTS: We enrolled 45 patients aged 65-79 years and 32 patients ≥80 years. Patients ≥80 years had significantly higher rates of Charlson comorbidity index (9.2 ± 2.4) than younger patients (6.5 ± 2.5; P < 0.001). Arterial hypertension, renal failure, and dementia were significantly more prevalent in octogenarians (P < 0.05). Patients aged ≥80 years had a significantly longer length of hospitalization, while the intensive care unit stay was similar between groups. In-hospital mortality was significantly greater in those ≥80 years (n = 3, 9.4% vs. n = 0, 0.0%; P = 0.029), whereas no differences in 90-day mortality or 30-day readmission were observed. In the second-stage analysis, significant improvements in blood infection parameters and neurologic status were detected in both groups. Of adverse events, pneumonia occurred significantly more frequently in patients aged ≥80 years. CONCLUSIONS: Surgical management leads to significant improvements in both laboratory and clinical parameters in older patients. Nevertheless, a personalized medical approach is mandatory in frail patients, especially octogenarians. A clear discussion regarding the potential risk is unambiguously recommended.

Decompression only versus fusion in octogenarians with spinal epidural abscesses: early complications, clinical and radiological outcome with 2-year follow-up.

Despite increased life expectancy due to health care quality improvements globally, pyogenic vertebral osteomyelitis (PVO) treatment with a spinal epidural abscess (SEA) remains challenging in patients older than 80 years. We aimed to assess octogenarians for PVO prevalence with SEA and compare after-surgery clinical outcomes of decompression and decompression and instrumentation. A retrospective review of electronic medical records at a single institution was conducted between September 2005 and December 2020. Patient demographics, surgical characteristics, complications, hospital course, and 90-day mortality were collected. Comorbidities were assessed using the age-adjusted Charlson comorbidity index (CCI). Over 16 years, 35 patients aged ≥80 years with PVO and SEA were identified. Eighteen patients underwent surgical decompression ("decompression group"), and 17 underwent surgical decompression with instrumentation ("instrumentation group"). Both groups had a CCI >6 (mean±SD, 8.9±2.1 vs. 9.6±2.7, respectively; p=0.065). Instrumentation group patients had a significantly longer hospital stay but no ICU stay. In-hospital and 90-days mortality rates were similar in both groups. The mean follow-up was 26.6±12.4 months. No further surgeries were performed. Infection levels and neurological status were improved in both groups at discharge. At the second-stage analysis, significant improvements in the blood infection parameters and the neurological status were detected in the decompression group. Octogenarians with PVO and SEA have a high adverse events risk after surgical procedures. Surgical decompression might contribute to earlier clinical recovery in older patients. Thus, the surgical approach should be discussed with patients and their relatives and be carefully weighed.
