Is there a need for lumbar orthosis in mild compression fractures of the thoracolumbar spine?: A retrospective study comparing the radiographic results between early ambulation with and without lumbar orthosis

2022 SPILF - Clinical Practice guidelines for the diagnosis and treatment of disco-vertebral infection in adults

These guidelines are an update of those made in 2007 at the request of the French Society of Infectious Diseases (SPILF, Société de Pathologie Infectieuse de Langue Française). They are intended for use by all healthcare professionals caring for patients with disco-vertebral infection (DVI) on spine, whether native or instrumented. They include evidence and opinion-based recommendations for the diagnosis and management of patients with DVI. ESR, PCT and scintigraphy, antibiotic therapy without microorganism identification (except for emergency situations), therapy longer than 6 weeks if the DVI is not complicated, contraindication for spinal osteosynthesis in a septic context, and prolonged dorsal decubitus are no longer to be done in DVI management. MRI study must include exploration of the entire spine with at least 2 orthogonal planes for the affected level(s). Several disco-vertebral samples must be performed if blood cultures are negative. Short, adapted treatment and directly oral antibiotherapy or early switch from intravenous to oral antibiotherapy are recommended. Consultation of a spine specialist should be requested to evaluate spinal stability. Early lifting of patients is recommended.

Compliance with wearing a thoracolumbar orthosis in nonoperative treatment of osteoporotic vertebral fractures: a prospective sensor-controlled study

BACKGROUND CONTEXT

Hyperextension orthoses (HOs) for nonoperative treatment of osteoporotic vertebral fractures (OVFs) are widely prescribed. However, the compliance, how much an HO is worn after it has been prescribed, is widely unknown.

PURPOSE

This study was performed to assess the wearing time of HOs for OVFs in a prospective blinded, sensor-controlled manner.

STUDY DESIGN / SETTING

A prospective, single blinded observational study was performed.

PATIENT SAMPLE

This study prospectively included 18 patients who were treated nonoperatively with an HO for OVFs.

OUTCOME MEASURES

The true wearing time was measured using a hidden temperature-based sensor. The patients were invited to return for regular follow-up every 2 weeks for 6 weeks, at which time clinical evaluation (including a visual analog scale for pain and the Oswestry disability questionnaire) and radiographs of the spine were performed.

METHODS

Full compliance was defined as a wearing time of 15 hours per day. Correlation between compliance and demographic differences, patient reported outcomes and radiographic changes of the vertebral structures were calculated.

RESULTS

The mean HO wearing time was 5.5±3.3 hours (37%±22% compliance). Female patients used the HO significantly longer per day than did male patients (6.5±3.2 vs 2.9±2.0 hours, p=.039). Age and body mass index had no influence on wearing behavior.

CONCLUSIONS

Overall, compliance with wearing HOs is poor and shows great variability with significant gender-dependency but not associated with BMI, age, or pain-level. Further studies are required to confirm our results that the wearing time does not have an influence on kyphotic progression of the osteoporotic fractured segment, nor on clinical outcome at short term.

[Treatment of trauma-related vertebral body fractures of the thoracic and lumbar spine with orthotic devices : A review]

BACKGROUND

Trauma-related fractures of the thoracic and lumbar spine occur after exposure to high kinetic energy. To assign patients to the correct kind of treatment the AO spine classification is used.

OBJECTIVE

The aim was to describe the role of orthotic devices in the treatment of thoracic and lumbar fractures in the nondegenerative spine.

MATERIAL AND METHODS

A review of the literature was carried out according to the PRISMA protocol (Preferred Reporting Items for Systematic reviews and Meta-Analyses) in PubMed, ScienceDirect, Cochrane and Google.Scholar. A total of 118 potentially important publications were found and 16 studies with a prospective study design could be included in this analysis. RoB 2 (Cochrane Risk of Bias tool in the second Version) in the case of randomized studies and the ROBINS‑I (Risk Of Bias In Nonrandomised Studies of Interventions) for nonrandomized studies were used to assess publication quality. The level of evidence was determined according to AHCPR (Agency for Health Care Policy and Research).

RESULTS

In the case of fractures (AO types A0-A3) without degenerative changes in the bone structure of the thoracic and lumbar spine without indications for operative procedure, conservative treatment with analgesia, physiotherapy and early mobilization is recommended and orthotic treatment is not superior. Surgical treatment, even in cases where conservative treatment was possible, led to improved functionality and pain sensation faster but there were no differences in the long-term results. Assessing the neurological functional deficit, the functional success of the treatment and the kyphosis angle were measured in different ways, reducing the extent of comparability. Although mainly a level of evidence Ib-IIa could be assigned, nearly all included studies had a high risk of bias.

CONCLUSION

In individual cases treatment with an orthotic device could be a helpful add-on in conservative treatment of fractures in the thoracic and lumbar spine. A treatment with orthotic devices alone cannot be recommended in these cases.

Reducing Radiation and Lowering Costs With a Standardized Care Pathway for Nonoperative Thoracolumbar Fractures

STUDY DESIGN

Retrospective observational study.

OBJECTIVE

There is marked variation in the management of nonoperative thoracolumbar (TL) compression and burst fractures. This was a quality improvement study designed to establish a standardized care pathway for TL fractures treated with bracing, and to then evaluate differences in radiographs, length of stay (LOS), and cost before and after the pathway.

METHODS

A standardized pathway was established for management of nonoperative TL burst and compression fractures (AOSpine classification type A1-A4 fractures). Bracing, radiographs, costs, complications, and LOS before and after pathway adoption were analyzed. Differences between the neurosurgery and orthopedic spine services were compared.

RESULTS

Between 2012 and 2015, 406 nonoperative burst and compression TL fractures were identified. A total of 183 (45.1%) were braced, 60.6% with a custom-made thoracolumbosacral orthosis (TLSO) and 39.4% with an off-the-shelf TLSO. The number of radiographs significantly reduced after initiation of the pathway (3.23 vs 2.63, P = .010). A total of 98.6% of braces were custom-made before the pathway; 69.6% were off-the-shelf after the pathway. The total cost for braced patients after pathway adoption decreased from $10 462.36 to $8928.58 (P = .078). Brace-associated costs were significantly less for off-the-shelf TSLO versus custom TLSO ($1352.41 vs $3719.53, respectively, P < .001). The mean LOS and complication rate did not change significantly following pathway adoption. The orthopedic spine service braced less frequently than the neurosurgery service (40.7% vs 52.2%, P = .023).

CONCLUSIONS

Standardized care pathways can reduce cost and radiation exposure without increasing complication rates in nonoperative management of thoracolumbar compression and burst fractures.

RADIOGRAPHIC EVALUATION OF THORACOLUMBAR STABILIZATION USING TWO DIFFERENT ORTHOSIS SYSTEMS

ABSTRACT Objective: To evaluate radiographically the stability of the thoracolumbar junction comparing the two types of thoracolumbosacral orthosis (TLSO) most used in our environment, the Jewett and the Boston braces. Methods: After approval by the institutional review board, nine participants were submitted to X-rays in the profile view, with the beam focused on T12, in the orthostatic position, maximal flexion without brace and maximal flexion with the Jewett and the Boston braces. The Cobb angle of the thoracolumbar junction (T10-L2) was measured and the values compared using the student T test (p <0.05). Results: The Boston brace promoted greater stabilization of the thoracolumbar junction during flexion of the trunk compared to the Jewett brace (p <0.05). In addition, there was no statistical difference in the Cobb angle of the thoracolumbar junction in the orthostatic (neutral) position and in flexion using the Boston brace. Conclusion: The Boston brace presented greater stabilization of the thoracolumbar region during flexion of the trunk compared to the Jewett brace. Level of Evidence II; Prospective comparative study.

The Conservative Treatment of Traumatic Thoracolumbar Vertebral Fractures

BACKGROUND

The conservative treatment of traumatic thoracolumbar vertebral fractures is often not clearly defined.

METHODS

This review is based on articles retrieved by a systematic search in the PubMed and Web of Science databases for publications up to February 2018 dealing with the conservative treatment of traumatic thoracolumbar vertebral fractures. The search initially yielded 3345 hits, of which 35 were suitable for use in this review.

RESULTS

It can be concluded from the available original clinical research on the subject, including three randomized controlled trials (RCTs), that the primary diagnostic evaluation should be with plain x-rays, in the standing position if possible. If a fracture is suspected on the plain films, computed tomography (CT) is indicated. Magnetic resonance imaging (MRI) is additionally advisable if there is a burst fracture. The spinal deformity resulting from the fracture should be quantified in terms of the Cobb angle. The choice of a conservative or operative treatment strategy is based on the primary stability of the fracture, the degree of deformity, the presence or absence of disc injury, and the patient's clinical state. Our analysis of the three RCTs implies that early functional therapy without a corset should be performed, although treatment in a corset may be appropriate to control pain. Follow-up x-rays should be obtained after mobilization and at one week, three weeks, six weeks, and twelve weeks.

CONCLUSION

Further comparative studies of the indications for surgery and specific conservative treatment modalities would be desirable.

Closed therapy of thoracic and lumbar vertebral body fractures in trauma patients

Background

The failure rate for the closed/non-surgical treatment of thoracic and lumbar vertebral body fractures (TLVBF) in trauma patients has not been adequately evaluated utilizing computed tomography (CT) studies.

Methods

From 2007 to 2008, consecutive trauma patients, who met inclusion criteria, with a CT diagnosis of acute TLVBF undergoing closed treatment were assessed. The failure rates for closed therapy, at 3 months post-trauma, were defined by progressive deformity, vertebral body collapse, or symptomatic/asymptomatic pseudarthrosis. The Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification was utilized to classify the fractures (groups A1 and non-A1 fractures) and were successively followed with CT studies.

Results

There were 54 patients with 91 fractures included in the study; 66 were A1 fractures, and 25 were non-A1 fractures. All had rigid bracing applied with flat and upright X-ray films performed to rule out instability. None had sustained spinal cord injuries. Thirteen patients (24%) failed closed therapy [e.g. 13 failed fractures (14%) out of 91 total fractures]. Five failed radiographically only (asymptomatic), and eight failed radiographically and clinically (symptomatic). A1 fractures had a 4.5% failure rate, while non-A1 fractures failed at a rate of 40%.

Conclusion

Failure of closed therapy for TLVBF in the trauma population is not insignificant. Non-A1 fractures had a much higher failure rate when compared to A1 fractures. We recommend close follow-up particularly of non-A1 fractures treated in closed fashion using successive CT studies.

Spinal Orthoses for Vertebral Osteoporosis and Osteoporotic Vertebral Fracture: A Systematic Review

OBJECTIVE

To systematically review the evidence of effectiveness of spinal orthoses for adults with vertebral osteoporosis.

DATA SOURCES

We conducted a systematic literature search using the databases of PubMed, MEDLINE, EMBASE, AMED, CINAHL, PEDro, and the Cochrane Library from January 1995 to October 2014.

STUDY SELECTION

Two reviewers evaluated eligibility. Randomized controlled trials (RCTs), pilot RCTs, and prospective nonrandomized controlled studies of spinal orthoses for people with vertebral osteoporosis or osteopenia with and without osteoporotic vertebral fracture (OVF) that examined outcomes related to fracture consolidation, pain, strength, posture, balance, physical function, quality of life, and complications were eligible.

DATA EXTRACTION

Two reviewers independently extracted data and evaluated methodological quality using a domain-based risk-of-bias approach.

DATA SYNTHESIS

Twelve studies were included: 8 RCTs or pilot RCTs and 4 nonrandomized studies involving 626 participants. Three studies (n=153) evaluated orthoses after acute OVF; none were of high quality. Complications were highest with rigid orthoses. Evidence that orthoses could affect vertebral deformity was lacking. Nine studies (n=473) of varying quality considered orthoses in subacute and longer rehabilitation. Three suggested a semirigid backpack thoracolumbar orthosis (TLO) could benefit strength, pain, posture, and quality of life. One found a weighted kypho-orthosis (WKO) improved balance.

CONCLUSIONS

The limited evidence about orthoses after acute OVF is inconclusive; better evidence of efficacy is needed, particularly when considering complications. The promising evidence regarding the backpack TLO and WKO needs to be explored further in studies of sufficient size and quality that include men.

The effects of orthosis on thoracolumbar fracture healing: A review of the literature

BACKGROUND

Various methods have been used as a conservative treatment of stable thoracolumbar fracture. Presently, it is controversial, whether the use of spinal orthoses reduces pain and deformity associated with vertebral fracture or not. Therefore, the aim of this study was to determine the effects of orthoses on vertebral fractures healing in thoracolumbar area.

MATERIALS AND METHODS

A search was carried out on Medline, ISI web of knowledge, Google Scholar and Embasco. The keywords used included thoracolumbar fracture; brace, orthosis, and conservative treatment.

RESULTS

Twenty-one papers were selected for final analysis. The quality of the most of the papers was poor, as most of them were retrospective studies with various follow-up periods.

DISCUSSION

Based on the results of these studies, it can be concluded that subjects with a fracture of thoracolumbar achieved a high ability to return to their jobs. The use of orthosis did not influence the kyphosis angulation in subjects with stable fracture in thoracolumbar spine. The effects of orthoses would be mostly immobilization, protection and remaining.

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

INTRODUCTION

Thoracolumbar spine fractures are common osteoporotic fractures among elderly patients. Several studies suggest that these fractures can be treated successfully with a nonoperative management. The aim of this study is to evaluate the conservative treatment of elderly patients with a vertebral fracture.

METHODS

This study is a retrospective cohort study, which included all patients with an age of 65 years and older, who were diagnosed with a vertebral fracture and where therefore admitted to the Geriatric Fracture Center over a period of 2 years. Primary outcome was the level of functioning 6 weeks and 3 months after admission.

RESULTS

We included 106 patients with 143 vertebral fractures, of which 61 patients were evaluated after 3 months. In our population, 53% of the patients had a fracture involving both middle and anterior columns. The majority of the patients functioned sufficiently 6 weeks and 3 months after admission. Analysis showed that age <80 years is an independent predictor of a sufficient level of functioning after 6 weeks.

DISCUSSION

The nonoperative treatment of elderly patients with a vertebral fracture leads to a sufficient level of functioning 6 weeks and 3 months after admission. In our population, only age <80 years is an independent predictor for a sufficient level of functioning 6 weeks after admission. The level of functioning at 6 weeks predicts the level of functioning 3 months after admission. On comparison, the level of functioning after early ambulation is equal to the level of functioning after immobilization. Where immobilization may lead to complications, early ambulation was not associated with new complications or neurological damage. Based on these advantages, the treatment of elderly patients with a fracture involving both middle and anterior columns may be altered from immobilization to mobilization in the future.

Orthosis for thoracolumbar burst fractures without neurologic deficit: A systematic review of prospective randomized controlled trials

BACKGROUND

Traditionally, conservative treatment of thoracolumbar (TL) burst fractures without neurologic deficit has encompassed the application of an extension brace. However, their effectiveness on maintaining the alignment, preventing posttraumatic deformities, and improving back pain, disability and quality of life is doubtful.

OBJECTIVE

The objective was to identify and summarize the evidence from randomized controlled trials (RCTs) to determine whether bracing patients who suffer TL fractures adds benefices to the conservative manage without bracing.

MATERIALS AND METHODS

Seven databases were searched for relevant RCTs that compared the clinical and radiological outcomes of orthosis versus no-orthosis for TL burst fractures managed conservatively. Primary outcomes were: (1) Loss of kyphotic angle; (2) failure of conservative management requiring subsequent surgery; and (3) disability and pain outcomes. Secondary outcomes were defined by health-related quality of life and in-hospital stay.

RESULTS

Based on predefined inclusion criteria, only two eligible high-quality RCTs with a total of 119 patients were included. No significant difference was identified between the two groups regarding loss of kyphotic angle, pain outcome, or in-hospital stay. The pooled data showed higher scores in physical and mental domains of the Short-Form Health Survey 36 in the group treated without orthosis.

CONCLUSION AND RECOMMENDATION

The current evidence suggests that orthosis could not be necessary when TL burst fractures without neurologic deficit are treated conservatively. However, due to limitations related with number and size of the included studies, more RCTs with high quality are desirable for making recommendations with more certainty.

Union rates and prognostic variables of osteoporotic vertebral fractures treated with a rigid external support

Object

External supports serve as a traditional treatment option for osteoporotic vertebral fractures (OVFs). However, the role of external supports in the treatment of OVF remains inconclusive. The purpose of this study was to determine the role of a rigid external support in the healing of OVFs by prospectively evaluating union (fracture settling) rates and prognostic variables for patients suffering from an incident OVF.

Methods

Fifty-five patients with acute back pain were enrolled in this study after being diagnosed with an OVF based on MRI findings. Patients were treated using a plastic thoracolumbosacral orthosis (TLSO) and underwent follow-up at 2, 3, and 6 months. Vertebrae were referred to as “settled” when there was no dynamic mobility on sitting lateral and supine lateral radiographs. At the time of the 3- and 6-month follow-up visits, the patients were divided into 2 groups, the “settled group” and the “unsettled group.” Patients in these groups were compared with regard to clinical and radiographic features.

Results

Of the 55 patients enrolled, 53 patients were followed up for 6 months. There were 14 men and 39 women with an average age of 75.3 years. Fracture settling of the affected vertebra was defined in 54.7% of the patients at 2 months, in 79.2% at 3 months, and in 88.7% at 6 months. All 5 components of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire improved significantly both at 3 months and 6 months. Patients in the unsettled group exhibited a statistically greater likelihood of having fractures at the thoracolumbar junction, Type A3 fractures, and fractures with a diffuse low-intensity area on T2-weighted MRI studies at 3 months. In contrast, at 6 months, the only statistically significant difference between the groups was patient age.

Conclusions

The biomechanical disadvantages of OVFs (location, type, and size) adversely influencing the fracture healing were overcome by the treatment using a TLSO within 6 months. The authors' findings show that a TLSO plays a biomechanical role in the healing of OVFs.

Osteoporotic vertebral fractures: current concepts of conservative care

INTRODUCTION

Osteoporotic vertebral compression fractures (VCFs) are a growing public health problem with important socio-economic effects in western countries. In the USA, 10 million people over 50 suffer from osteoporosis. In these patients, 1.5 million annual fractures have been registered, and 50% of these are vertebral compression.

SOURCES OF DATA

We performed a comprehensive search of PubMed, Medline, Cochrane, CINAHL and Embase databases using various combinations of the keywords 'osteoporosis', 'vertebral compression fractures', 'brace', 'bracing', 'orthosis', 'conservative management' and 'rehabilitation' over the years 1966-2011. All articles relevant to the subject were retrieved, and their bibliographies were hand searched for further references in the context of conservative management of osteoporotic vertebral fractures.

AREAS OF AGREEMENT

Conservative management for patients with osteoporotic vertebral fractures includes bed rest, pain medication, physiotherapy and bracing.

AREAS OF CONTROVERSY

A conservative management for patients with osteoporotic VCFs s has not been standardized. The utility of vertebral augmentation techniques has been questioned by recent randomized controlled trials.

GROWING POINTS

Randomized controlled trials are being performed worldwide on vertebral augmentation techniques.

AREAS TIMELY FOR DEVELOPING RESEARCH

Although spinal orthoses are commonly used for the management of patients with osteoporotic vertebral fractures, in the literature there is only one randomized controlled trial on bracing for this condition. While the best conservative management for subjects with osteoporotic VCFs s is not defined and standardized, no conclusions on the superiority of vertebral augmentation techniques over conservative management can be drawn.

Conservative management of patients with an osteoporotic vertebral fracture

Osteoporotic vertebral compression fractures (VCFs) are an increasing public health problem. Recently, randomised controlled trials on the use of kyphoplasty and vertebroplasty in the treatment of these fractures have been published, but no definitive conclusions have been reached on the role of these interventions. The major problem encountered when trying to perform a meta-analysis of the available studies for the use of cementoplasty in patients with a VCF is that conservative management has not been standardised. Forms of conservative treatment commonly used in these patients include bed rest, analgesic medication, physiotherapy and bracing.

In this review, we report the best evidence available on the conservative care of patients with osteoporotic VCFs and associated back pain, focusing on the role of the most commonly used spinal orthoses. Although orthoses are used for the management of these patients, to date, there has been only one randomised controlled trial published evaluating their value. Until the best conservative management for patients with VCFs is defined and standardised, no conclusions can be drawn on the superiority or otherwise of cementoplasty techniques over conservative management.

Importância da realização de radiografias em posição ortostática na avaliação inicial de pacientes com fraturas toracolombares

OBJETIVO: o manejo das fraturas toracolombares estáveis é controverso, especialmente em pacientes sem déficit funcional. Este estudo questiona o motivo de ser realizada uma avaliação das imagens apenas na posição supina, uma vez que, paradoxalmente, o tratamento conservador inclui o ortostatismo precoce. O propósito deste estudo é determinar se a realização de radiografias em posição ortostática influencia na definição do tratamento dos pacientes com fraturas torácicas e lombares classificadas como tipo "A" da AO-ASIF. MÉTODOS: de janeiro de 2007 a novembro de 2008, foram avaliados pacientes portadores de fraturas torácicas e lombares por meio de radiografias em decúbito e tomografia computadorizada, visando identificar sinais de instabilidade. As fraturas classificadas radiograficamente como tipo "A" da AO-ASIF, inicialmente por tratamento conservador, foram submetidas à realização de radiografias em ortostatismo sem o colete ortótico na fase aguda e seus parâmetros radiológicos foram reavaliados. RESULTADOS: foram incluídos neste estudo 59 pacientes com fraturas toracolombares estáveis (T11 a L4), e todos toleraram o exame. A cifose vertebral aumentou 46,8%. O colapso anterior aumentou 15,52%. Três destes pacientes (5,1%) receberam a indicação cirúrgica após radiografias em ortostatismo por apresentarem critérios de instabilidade. CONCLUSÕES: a realização das radiografias em ortostatismo mostrou-se eficiente na identificação de pacientes com instabilidade ainda não manifesta e capaz de predizer a evolução satisfatória durante o tratamento conservador, além de ser um exame diagnóstico seguro, de fácil aplicabilidade e com baixo custo. Neste estudo, um total de 5,1% dos pacientes tiveram seu tratamento conservador alterado para o cirúrgico.

Nonoperative treatment of thoracic and lumbar spine fractures: a prospective randomized study of different treatment options

OBJECTIVES

To evaluate and compare nonoperative treatment methods for traumatic thoracic and lumbar compression fractures and burst fractures.

DESIGN

Prospective randomized controlled trial with long-term follow-up.

SETTING

Two general hospitals in the Netherlands.

PATIENTS/PARTICIPANTS

Patients with a traumatic thoracic or lumbar spine fracture, without neurologic damage, with less than 50% loss of height of the anterior column and less than 30% reduction of the spinal canal were included.

INTERVENTION

Patients in the compression group were randomized to physical therapy and postural instructions, a brace for 6 weeks, or a Plaster of Paris cast for 6 or 12 weeks. Patients in the burst group received a brace or a Plaster of Paris cast, both for 12 weeks.

MAIN OUTCOME MEASUREMENTS

Follow-up examinations included radiographs, Visual Analogue Scores for toleration of treatment and persistent pain, and an Oswestry Disability Index at long-term follow-up.

RESULTS

There were 133 patients: 108 in the compression group and 25 in the burst group. For compression fractures, physical therapy and brace were considered the most tolerable. Brace therapy scored significantly better on the Visual Analogue Scores for residual pain and on the Oswestry Disability Index. None of the treatments had any significant effect on the residual deformity measurements. For burst fractures, no significant differences were found.

CONCLUSIONS

Brace treatment with supplementary physical therapy is the treatment of choice for patients with compression fractures of the thoracic and lumbar spine. Furthermore, more than 20% of all patients had moderate or severe back pain at long-term follow-up.

No evidence for the effectiveness of bracing in patients with thoracolumbar fractures

BACKGROUND AND PURPOSE

The use of braces is widespread in patients with thoracolumbar fractures. The effectiveness of bracing, however, is controversial. We sought evidence for the effect of bracing in patients with traumatic thoracolumbar fractures based on outcome and length of hospital stay (LOS). Furthermore, we evaluated the incidence of complications of bracing.

METHODS

An electronic search strategy with extensive MeSH headings was used in various databases to identify studies that compared bracing and non-bracing therapies. Two reviewers independently selected systematic reviews, randomized controlled trials (RCTs), controlled clinical trials, and observational studies, and both assessed the methodological quality and extracted the data.

RESULTS

No systematic reviews or RCTs were found. 7 retrospective studies were included. None of these studies showed an effect of bracing. Because of poor methodological quality, no best-evidence synthesis could be performed. One observational study was selected in which a complication of bracing was reported.

INTERPRETATION

In the present literature, there is no evidence for the effectiveness of bracing in patients with traumatic thoracolumbar fractures. The lack of high-quality studies prevents relevant conclusions from being drawn.

Nonoperative management and treatment of spinal injuries

STUDY DESIGN

Review of literature.

OBJECTIVE

To delineate and discuss nonoperative treatment and treatment of spinal injuries.

SUMMARY OF BACKGROUND DATA

Nonoperative methods have been a mainstay of care for spinal injuries since ancient Egypt. The vast majority of all spinal injuries should be treated in the nonoperative fashion. The indications and methods continue to evolve.

METHODS

A PubMed search of the literature returned more than 1000 articles related to spine trauma. A total of 270 were references to nonoperative treatment, and 100 were thought to be relevant and included in this review.

RESULTS

All spine injuries are treated in a nonoperative manner, at least initially. The vast majority of injuries are successfully and appropriately treated in a definitive manner with nonsurgical methods. Over the past 10-15 years, the advent of better rigid cervical fixation has decreased the use of halo vests as definitive treatment of many cervical injuries. In contrast, during the same time, more thoracolumbar injuries are being treated in a nonsurgical fashion because the outcomes have been shown to be similar or superior.

CONCLUSIONS

As with all of medicine, the treatment of spine trauma will continue to evolve with time. It is paramount that the physician selects the treatment that will provide the best short-term recovery with the least impact on long-term function.

Comparison of Motion Restriction and Trunk Stiffness Provided by Three Thoracolumbosacral Orthoses (TLSOs)

The amounts of thoracic and lumbar spine motion restriction and passive trunk stiffness provided by three thoracolumbosacral orthoses (TLSOs) (Aspen TLSO, Boston Body Jacket, and CAMP TLSO) were compared. Ten subjects executed maximum trunk flexion, extension, and lateral bending motions. The spine motion was measured noninvasively with a thin strain gauge device (Flexducer), and passive trunk stiffness around the neutral posture was estimated from an electromyography-assisted biomechanical model. No significant differences in either the restriction of motion or the amount of added passive trunk stiffness were found between the three orthoses. The subjects also did not perceive any difference in the restriction of motion but rated the Aspen TLSO significantly more comfortable than the other two orthoses. The rigid custom orthosis design may not be important for restricting the spine motion and providing passive trunk stiffness, or there may be other measures that reflect better the function of orthoses.
