Thoracolumbar spine fractures in the geriatric fracture center: early ambulation leads to good results on short term and is a successful and safe alternative compared to immobilization in elderly patients with two-column vertebral fractures

Guideline summary review: An evidence-based clinical guideline for the diagnosis and treatment of adults with osteoporotic vertebral compression fractures

BACKGROUND CONTEXT

The North American Spine Society's (NASS) Evidence-Based Clinical Guideline for the Diagnosis and Treatment of Adults with Osteoporotic Vertebral Compression Fractures features evidence-based recommendations for diagnosing and treating adult patients with osteoporotic vertebral compression fractures. The guideline is intended to reflect contemporary treatment concepts for osteoporotic vertebral compression fractures as reflected in the highest quality clinical literature available on this subject as of September 2020.

PURPOSE

The purpose of the guideline is to provide an evidence-based educational tool to assist spine specialists when making clinical decisions for adult patients with osteoporotic vertebral compression fractures. This article provides a brief summary of the evidence-based guideline recommendations for diagnosing and treating patients with this condition.

STUDY DESIGN

This is a guideline summary review.

METHODS

This guideline is the product of NASS' Clinical Practice Guidelines Committee. The methods used to develop this guideline are detailed in the complete guideline and technical report available on the NASS website. In brief, a multidisciplinary work group of spine care specialists convened to identify clinical questions to address in the guideline. The literature search strategy was developed in consultation with a medical librarian. Upon completion of the systematic literature search, evidence relevant to the clinical questions posed in the guideline was reviewed. Work group members utilized NASS evidentiary table templates to summarize study conclusions, identify study strengths and weaknesses, and assign levels of evidence. Work group members participated in recommendation meetings to update and formulate evidence-based recommendations and incorporate expert opinion when necessary. The draft guideline was submitted to an internal and external peer review process and ultimately approved by the NASS Board of Directors.

RESULTS

Twenty-nine clinical questions were addressed, and the answers are summarized in this article. The respective recommendations were graded according to the levels of evidence of the supporting literature.

CONCLUSIONS

The evidence-based clinical guideline has been created using techniques of evidence-based medicine and best available evidence to aid practitioners in the diagnosis and treatment of adult patients with osteoporotic vertebral compression fractures. The entire guideline document, including the evidentiary tables, literature search parameters, literature attrition flowchart, suggestions for future research, and all of the references, is available electronically on the NASS website at http://www.spine.org/guidelines.

Outcome of traumatic thoracolumbar spine fractures in elderly: A systematic review

Introduction

Adequate guidelines for treatment of people over 65 years, suffering traumatic thoracolumbar spine fractures without neurologic deficit, are currently lacking.

Research question

The aim of this study was to systematically review the available literature regarding the outcome of conservative and surgical treatment of thoracolumbar spinal trauma in elderly patients.

Material and methods

A systematic review according the PRISMA guidelines was performed. Pubmed, Web of Science, EMBASE and the Cochrane Central register were searched until June 2021. Risk of bias of the included studies was evaluated. Clinical and radiological results, as well as complications of conservative or surgical treatment were reviewed.

Results

Six articles were included (one prospective randomized trial, two prospective and three retrospective cohort studies). In these studies conflicting results were observed with regard to pain, radiological results and complications following both conservative and surgical treatment strategies for thoracolumbar spine fractures in elderly.

Discussion and conclusion

Treatment of thoracolumbar fractures in elderly should focus on early mobilization to reduce complications and hospital stay. This may improve functional outcome and prevent worsening of frailty in this vulnerable group of patients. To elucidate the optimal treatment for elderly patient with thoracolumbar fractures, future research should focus on patient specific treatment rather than the mere difference between outcome of surgical and conservative treatment.

Trauma (Excluding Falls) in the Older Adult

Trauma in the older adult will increasingly become important to emergency physicians hoping to optimize their patient care. The geriatric patient population possesses higher rates of comorbidities that increase their risk for trauma and make their care more challenging. By considering the nuances that accompany the critical stabilization and injury-specific management of geriatric trauma patients, emergency physicians can decrease the prevalence of adverse outcomes.

Exploring elderly patients' experiences and concerns about early mobilization implemented in postoperative care following lumbar spinal surgery: a qualitative study

BACKGROUND

Given its apparent benefits, early mobilization is becoming increasingly important in spinal surgery. However, the time point at which patients first get out of bed for mobilization after spinal surgery varies widely. Beginning in January 2022, we conducted a study of early mobilization (mobilization within 4 h postoperatively) following multi-segment lumbar decompression and fusion surgery in elderly patients. The study goal was to better understand elderly patients' perceptions of early mobilization and ultimately contribute to the improvement of elderly patients' perioperative experiences and quality of life.

METHODS

We employed a qualitative descriptive study design involving face-to-face semi-structured interviews. Forty-five consecutive patients were invited, among whom 24 were enrolled and completed the qualitative investigation from February to June 2022. Of these 24 patients, 10 underwent early mobilization (mobilization within 4 h postoperatively) and 14 underwent mobilization at ≥ 24 h postoperatively. Three researchers conducted a 15-question interview the day before each patient's discharge. The interviews were audio-recorded, and content analysis was used to assess the data.

RESULTS

Six themes regarding the patients' experiences and concerns about early mobilization were identified: worries, benefits, daily routines, pain, education, and support. The study results revealed the obstacles in early mobilization practice and highlighted the importance of perioperative education on early mobilization.

CONCLUSIONS

Clear and explicit guidance on early mobilization and a multidisciplinary mobilization protocol that incorporates a comprehensive pain management plan are essential for effective patient education. These measures may have positive effects on reducing patients' stress and anxiety regarding postoperative early mobilization.

Thoraco-lumbar-sacral orthoses in older people - A narrative literature review

Fractures in the thoracolumbar region have a bimodal distribution, with an increasing number of older people presenting with acute vertebral fractures after atraumatic or low energy mechanisms of injury. In the absence of neurological compromise and significant vertebral instability, thoracolumbar fractures are often managed conservatively and bracing is widely recommended. However, in older cohorts, bracing is often ill fitting and poorly tolerated with non-compliance leading to prolonged immobilization. Systematic reviews and meta-analyses have challenged the motive of bracing, but as evidence quality is low, the role of exploratory analysis has been limited. This descriptive review summarises and examines the current evidence that underpins the use of spinal orthoses, specific to older patients, in an effort to streamline its judicious use in clinical practice and identify scope to direct further research.

Is Routine Use of Drain Really Necessary for Posterior Lumbar Interbody Fusion Surgery? A Retrospective Case Series with a Historical Control Group

STUDY DESIGN

A retrospective case-control study.

OBJECTIVES

The usefulness of a drain in spinal surgery has always been controversial. The purposes of this study were to determine the incidence of hematoma-related complications after posterior lumbar interbody fusion (PLIF) without a drain and to evaluate its usefulness.

METHODS

We included 347 consecutive patients with degenerative lumbar disease who underwent single- or double-level PLIF. The participants were divided into 2 groups by the use of a drain or not; drain group and no-drain group.

RESULTS

In 165 cases of PLIF without drain, there was neither a newly developed neurological deficit due to hematoma nor reoperation for hematoma evacuation. In the no-drain group, there were 5 (3.0%) patients who suffered from surgical site infection (SSI), all superficial, and 17 (10.3%) patients who complained of postoperative transient recurred leg pain, all treated conservatively. Days from surgery to ambulation and length of hospital stay (LOS) of the no-drain group were faster than those of the drain group (P < 0.001). In a multiple regression analysis, a drain insertion was found to have a significant effect on the delayed ambulation and increased LOS. No significant differences existed between the 2 groups in additional surgery for hematoma evacuation, or SSI.

CONCLUSIONS

No hematoma-related neurological deficits or reoperations caused by epidural hematoma and SSI were observed in the no-drain group. The no-drain group did not show significantly more frequent postoperative complications than the drain use group, hence the routine insertion of a drain following PLIF should be reconsidered carefully.

Awake Percutaneous Fixation for Unstable Fractures of the Spine in High-risk Patients: A Retrospective Study

INTRODUCTION

Unstable fractures in sick or elderly patients are on the rise. These patients who are at high risk for surgery present a challenge for surgeons and anesthesiologists. In patients with American Society of Anesthesiologists (ASA) scores 3 to 4, the risk is even higher because of the high rate of intraoperative complications.

METHODS

All patients with ASA scores 3 to 4 who presented with unstable fractures of the spine to a level-one trauma center were assessed, and they underwent awake spinal percutaneous fixation, with mild sedation and local anesthesia. Demographics, radiology, and the outcome were collected.

RESULTS

Nineteen patients were operated between the years 2019 and 2021. Average follow-up was 12 months (range 8 to 24 months); six patients were female and 13 males. The average age was 77.7 years; the ASA score was 3 to 4 in all patients. There were 10 extension-type injuries, six unstable burst injuries, two chance fractures, and one teardrop fracture. All patients underwent unilateral fixation, and just one patient underwent bilateral fixation; cement augmentation was done in 16 of the patients. No neurologic complication was observed. One case of infection presented 4 months after surgery. All patients were discharged ambulating.

CONCLUSIONS

Awake fixation in extreme cases is safe and feasible; a dedicated team including an anesthesiologist and radiologist is needed to treat these cases safely and quickly.

Early mobilization reduces the medical care cost and the risk of disuse syndrome in patients with acute osteoporotic vertebral fractures

STUDY DESIGN

A retrospective observational study.

PURPOSE

To compare two conservative treatments for acute osteoporotic vertebral fractures (OVFs).

OVERVIEW OF LITERATURE

Several studies have reported conservative treatments for OVFs in terms of using a brace, rehabilitation, and bed rest. However, there is no consensus about the conservative treatment for OVFs.

METHODS

We evaluated 68 patients with acute OVF treated in our hospital from 2007 to 2011. Thirty-four patients treated in prolonged bed rest (PBR) regimen underwent rehabilitation wearing a Jewett's brace after three weeks of bed rest. In contrast, the other 34 patients underwent rehabilitation wearing a Jewett's brace as soon as possible, which we called a stir-up (SU) regimen. We compared two treatment groups for medical costs, hospital length of stay (LOS), pain according to the numeric rating scale (NRS), the activities of daily living (ADL), and imaging studies.

RESULTS

The average hospital LOS was significantly shorter in patients treated by the SU regimen, which resulted in the medical costs reduction. There was no significant difference in the NRS through 6 months between the two groups. Although many patients in both groups experienced at least one level reduction in ADL at 6 months after the injury, patients in the SU group tended to maintain their pre-injury ADL, which almost agrees with past reports. In terms of imaging studies, patients in the PBR group showed milder vertebral compression rate over time. Pseudoarthrosis occurred in 2 patients in the SU group, who presented with mild pain, which had little influence on their daily lives.

CONCLUSION

We compared two conservative treatments for OVFs. Early rehabilitation was useful treatment for OVFs to minimize the risk for disuse syndrome, maintain pre-injury ADL status, and reduce the medical costs.

Comparison of Minimally Invasive Lateral Lumbar Interbody Fusion, Minimally Invasive Lateral Lumbar Interbody Fusion, and Open Posterior Lumbar Interbody Fusion in the Treatment of Single-Level Spondylolisthesis of L4-L5

OBJECTIVE

To compare the outcomes of minimally invasive lateral lumbar interbody fusion (LLIF) with minimally invasive transforaminal lumbar interbody fusion (TLIF) and conventional open posterior lumbar interbody fusion (PLIF) for treating single-level spondylolisthesis at L4-L5.

METHODS

The patients underwent minimally invasive LLIF (n = 18), minimally invasive TLIF (n = 17), and conventional open PLIF (n = 20) for spondylolisthesis at L4-L5. Reduction of slippage, improvement in segmental lordosis, and restoration of foraminal height were measured. Perioperative parameters such as blood loss and operation time and clinical outcomes such as visual analog scale score and Oswestry Disability Index were compared.

RESULTS

Compared with the open PLIF group, the minimally invasive LLIF group showed greater restoration of mean foraminal height, significantly smaller mean intraoperative estimated blood loss, and less mean hemoglobin reduction on the third day postoperatively. Compared with the minimally invasive TLIF group, the minimally invasive LLIF group showed greater restoration of mean segmental lordosis. The minimally invasive LLIF group showed a significantly shorter mean time to start walking after surgery compared with the conventional open PLIF and minimally invasive TLIF groups. However, compared with the minimally invasive TLIF group, the minimally invasive LLIF group showed a significantly longer mean operating time. Clinical outcomes were not statistically different among the 3 groups.

CONCLUSIONS

In the treatment of spondylolisthesis of L4-L5, minimally invasive LLIF provided an effective surgical alternative to minimally invasive TLIF or conventional open PLIF, with the advantages of less blood loss, the faster start of postoperative walking, and comparable improvement in radiologic parameters.

Osteoporotic Fractures of the Thoracic and Lumbar Vertebrae: Diagnosis and Conservative Treatment

BACKGROUND

The prevalence of osteoporotic vertebral body fractures in Europe is 18-26%. Although most of these injuries can be treated conservatively, the underlying concepts have not been defined clearly or uniformly. In this article, we present the current state of the evidence on the diagnosis and conservative treatment of osteoporotic fractures of the thoracic and lumbar vertebrae.

METHODS

A systematic review of the literature up to May 2020 was carried out in the PubMed and Web of Science Core Collection databases. 549 articles were identified, of which 36 were suitable for inclusion in the review. Articles were sought in the areas of diagnosis, provision of physical aids, pharmacotherapy, physiotherapy, and treatments from the realm of alternative medicine.

RESULTS

The primary diagnostic technique was conventional x-ray in two planes (with the patient standing, if possible), which had 51.3% sensitivity and 75% specificity. If a fracture was suspected, magnetic resonance imaging (MRI) of the entire spine and regional computed tomography (CT) were carried out. The overall state of the evidence on treatment is poor; the best available evidence is for exercise therapy and physiotherapy, which are supported by three level I and four level II studies. Improvements were seen mainly in mobility and a reduced fear of falling. The use of an active orthosis can be useful as well. No evidence was found on the use of drugs or alternative medicine exclusively in the conservative treatment of osteoporotic vertebral body fractures.

CONCLUSION

It is reasonable to evaluate instability with imaging repeatedly, at regular intervals, over a period of six months. There is still a lack of reliable data on the optimal intensity and duration of physiotherapy, and on the use of orthoses.

Geriatric Trauma

Geriatric trauma patients will continue to increase in prevalence as the population ages, and many specific considerations need to be made to provide appropriate care to these patients. This article outlines common presentations of trauma in geriatric patients, with consideration to baseline physiologic function and patterns of injury that may be more prevalent in geriatric populations. Additionally, the article explores specific evidence-based management practices, the significance of trauma team and geriatrician involvement, and disposition decisions.

Rural older people had lower mortality after accidental falls than non-rural older people

Objective

This study aimed to investigate the mortality rate after falls of rural and non-rural older people and to explore the risk factors of mortality after falls among older people.

Patients and methods

This population-based case–control study identified two groups from a nationwide claim database (National Health Insurance Research Database in Taiwan): a rural group and a non-rural group, which included 3,897 and 5,541 older people, respectively, who were hospitalized for accidental falls (The International Classification of Diseases, Ninth Revision, Clinical Modification: E880–E888) during 2006–2009. Both groups were followed up for 4 years after falls. Four-year cumulative all-cause mortality rate after falls was calculated, and the demographic factor, comorbidity, and medications were considered as the potential risk factors of mortality after falls.

Results

The rural group had a significantly higher frequency of fall-related hospitalizations (7.4% vs 4.3%, P<0.001), but a lower 4-year cumulative all-cause mortality rate after falls than the non-rural group (8.8% vs 23.4%, P<0.001). After adjusting for age, gender, comorbidity, and medication use, the rural group had a significantly lower risk of mortality after falls than the non-rural group (adjusted odds ratio =0.32, 95% confidence interval =0.28–0.37, P<0.001). Age, gender, place of residence, comorbidity, number of medications, and inappropriate medication use were independent risk factors of mortality after falls.

Conclusion

The rural older people had a higher frequency of fall-related hospitalizations but lower mortality after falls than the non-rural older people. Fall prevention programs should be adjusted for difference in place of residence.

Perioperative morbidity and mortality after lumbar trauma in the elderly

OBJECT Traumatic fractures of the thoracolumbar spine are common injuries, accounting for approximately 90% of all spinal trauma. Lumbar spine trauma in the elderly is a growing public health problem with relatively little evidence to guide clinical management. The authors sought to characterize the complications, morbidity, and mortality associated with surgical and nonsurgical management in elderly patients with traumatic fractures of the lumbar spine. METHODS Using the National Sample Program of the National Trauma Data Bank, the authors performed a retrospective analysis of patients ≥ 55 years of age who had traumatic fracture to the lumbar spine. This group was divided into middle-aged (55-69 years) and elderly (≥ 70 years) cohorts. Cohorts were subdivided into nonoperative, vertebroplasty or kyphoplasty, noninstrumented surgery, and instrumented surgery. Univariate and multivariable analyses were used to characterize and identify predictors of medical and surgical complications, mortality, hospital length of stay, ICU length of stay, number of days on ventilator, and hospital discharge in each subgroup. Adjusted odds ratios, mean differences, and associated 95% CIs were reported. Statistical significance was assessed at p < 0.05, and the Bonferroni correction for multiple comparisons was applied for each outcome analysis. RESULTS Between 2003 and 2012, 22,835 people met the inclusion criteria, which represents 94,103 incidents nationally. Analyses revealed a similar medical and surgical complication profile between age groups. The most prevalent medical complications were pneumonia (7.0%), acute respiratory distress syndrome (3.6%), and deep venous thrombosis (3%). Surgical site infections occurred in 6.3% of cases. Instrumented surgery was associated with the highest odds of each complication (p < 0.001). The inpatient mortality rate was 6.8% for all subjects. Multivariable analyses demonstrated that age ≥ 70 years was an independent predictor of mortality (OR 3.16, 95% CI 2.77-3.60), whereas instrumented surgery (multivariable OR 0.38, 95% CI 0.28-0.52) and vertebroplasty or kyphoplasty (OR 0.27, 95% CI 0.17-0.45) were associated with decreased odds of death. In surviving patients, both older age (OR 0.32, 95% CI 0.30-0.34) and instrumented fusion (OR 0.37, 95% CI 0.33-0.41) were associated with decreased odds of discharge to home. CONCLUSIONS The present study confirms that lumbar surgery in the elderly is associated with increased morbidity. In particular, instrumented fusion is associated with periprocedural complications, prolonged hospitalization, and a decreased likelihood of being discharged home. However, fusion surgery is also associated with reduced mortality. Age alone should not be an exclusionary factor in identifying surgical candidates for instrumented lumbar spinal fusion. Future studies are needed to confirm these findings.
