Cervical epidural hematoma after spinal manipulation therapy: case report

Brown-Sequard syndrome after manual manipulation of the cervical spine: case report

INTRODUCTION

Spinal cord injury after manual manipulation of the cervical spine is rare and has never been described resulting from a patient performing a manual manipulation on their own cervical spine. To the best of our knowledge, this is the first well-documented case of this association.

CASE PRESENTATION

A healthy 29-year-old man developed Brown-Sequard syndrome immediately after performing a manipulation on his own cervical spine. Imaging showed large disc herniations at the levels of C4-C5 and C5-C6 with severe cord compression, so the patient underwent emergent surgical decompression. He was discharged to an acute rehabilitation hospital, where he made a full functional recovery by postoperative day 8.

CONCLUSION

This case highlights the benefit of swift surgical intervention followed by intensive inpatient rehab. It also serves as a warning for those who perform self-cervical manipulation.

Spinal epidural hematoma after spinal manipulation therapy: Report of three cases and a literature review

BACKGROUND

Spinal manipulation therapy (SMT) has been widely used worldwide to treat musculoskeletal diseases, but it can cause serious adverse events. Spinal epidural hematoma (SEH) caused by SMT is a rare emergency that can cause neurological dysfunction. We herein report three cases of SEH after SMT.

CASE SUMMARY

The first case was a 30-year-old woman who experienced neck pain and numbness in both upper limbs immediately after SMT. Her symptoms persisted after 3 d of conservative treatment, and she was admitted to our hospital. Magnetic resonance imaging (MRI) demonstrated an SEH, extending from C6 to C7. The second case was a 55-year-old man with sudden back pain 1 d after SMT, numbness in both lower limbs, an inability to stand or walk, and difficulty urinating. MRI revealed an SEH, extending from T1 to T3. The third case was a 28-year-old man who suddenly developed symptoms of numbness in both lower limbs 4 h after SMT. He was unable to stand or walk and experienced mild back pain. MRI revealed an SEH, extending from T1 to T2. All three patients underwent surgery after failed conservative treatment. The three cases recovered to ASIA grade E on day 5, 1 wk, and day 10 after surgery, respectively. All patients returned to normal after 3 mo of follow-up.

CONCLUSION

SEH caused by SMT is very rare, and the condition of each patient should be evaluated in full detail before operation. SEH should be diagnosed immediately and actively treated by surgery.

Cervical epidural hematoma after spinal manipulation therapy: a case report

BACKGROUND

Cervical spinal manipulation therapy is a common non-invasive treatment for neck pain and stiffness, and has been widely used in the population. However, most people do not pay attention to the potential risks of neck manipulation, such as ligament damage, fractures, and spinal cord injuries. Epidural hematoma is a disease in which blood accumulates in the epidural space of the vertebral body. This disease is usually caused by trauma or iatrogenic surgery, and may be associated with blood coagulopathies, neoplasms, or degenerative spinal disease. Reports of epidural hematoma caused by cervical spinal manipulation are rare.

CASE PRESENTATION

We present the case of a patient with tetraplegia and spinal shock after neck manipulation. A physical examination of the patient on admission found tenderness in the neck and increased muscle tension in both upper limbs. The superficial sensation of the upper limb disappeared, but the deep sensation still remained. The lower extremity had 0/5 power on both sides. The sensation below the T2 level completely disappeared. A cervical magnetic resonance imaging scan showed an acute posterior epidural hematoma from the C3-T3 vertebrae. Ultimately, the patient underwent emergency hematoma removal and showed partial improvement in symptoms of paralysis during follow-up.

CONCLUSIONS

Although spinal manipulation is simple and neck pain is common and recurrent in the general population, the basic condition and disease history of patients should be determined before manipulation. For high-risk patients, caution should be applied for cervical spinal manipulation or it should be prohibited. For a suspected hematoma, MRI should be used at an early stage to diagnose and locate the hematoma.

What are the risks of manual treatment of the spine? A scoping review for clinicians

Background

Communicating to patients the risks of manual treatment to the spine is an important, but challenging element of informed consent. This scoping review aimed to characterise and summarise the available literature on risks and to describe implications for clinical practice and research.

Method

A methodological framework for scoping reviews was followed. Systematic searches were conducted during June 2017. The quantity, nature and sources of literature were described. Findings of included studies were narratively summarised, highlighting key clinical points.

Results

Two hundred and fifty articles were included. Cases of serious adverse events were reported. Observational studies, randomised studies and systematic reviews were also identified, reporting both benign and serious adverse events.Benign adverse events were reported to occur commonly in adults and children. Predictive factors for risk are unclear, but for neck pain patients might include higher levels of neck disability or cervical manipulation. In neck pain patients benign adverse events may result in poorer short term, but not long term outcomes.Serious adverse event incidence estimates ranged from 1 per 2 million manipulations to 13 per 10,000 patients. Cases are reported in adults and children, including spinal or neurological problems as well as cervical arterial strokes. Case-control studies indicate some association, in the under 45 years age group, between manual interventions and cervical arterial stroke, however it is unclear whether this is causal. Elderly patients have no greater risk of traumatic injury compared with visiting a medical practitioner for neuro-musculoskeletal problems, however some underlying conditions may increase risk.

Conclusion

Existing literature indicates that benign adverse events following manual treatments to the spine are common, while serious adverse events are rare. The incidence and causal relationships with serious adverse events are challenging to establish, with gaps in the literature and inherent methodological limitations of studies. Clinicians should ensure that patients are informed of risks during the consent process. Since serious adverse events could result from pre-existing pathologies, assessment for signs or symptoms of these is important. Clinicians may also contribute to furthering understanding by utilising patient safety incident reporting and learning systems where adverse events have occurred.

Is neck massage safe? A rare case of tetraplegia and spinal shock after neck manipulation

Neck manipulation is associated with spinal cord injury. However, occurrence of such cases is infrequent. This article presents a 33-year-old gentleman who sustained acute tetraplegia after neck manipulation. The aim of this case report is to create awareness that vigorous neck manipulation could cause injury to the spinal cord.

Hemorrhagic thoracic schwannoma presenting with intradural hematoma and acute paraplegia after spinal manipulation therapy

Hemorrhagic conversion of spinal schwannomas represents a rare occurrence; also rare is the development of a spinal intradural hematoma after spinal manipulation therapy. We report a unique presentation of paraplegia in a patient who underwent spinal manipulation therapy and was found to have a hemorrhagic thoracic schwannoma at time of surgery in the setting of anti-platelet therapy use. In patients with spinal schwannomas, tumor hemorrhage is a rare occasion, which can be considered in the setting of additive effects of spinal manipulation therapy and antiplatelet therapy.

Idiopathic Thoracic Spontaneous Spinal Epidural Hematoma

A 33-year-old male patient experienced temporary sensory loss and weakness in the right lower extremity one month prior to admission. The patient was admitted to a private clinic with a three-day history of acute onset of sensory loss and weakness in both lower extremities and was treated and followed up with a prediagnosis of transverse myelitis and the Guillain-Barre syndrome (GBS). The patient was subsequently transferred to our clinic and the neurologic examination revealed paraplegia in both lower extremities, positive bilateral Babinski signs, and hypesthesia below the T10 dermatome with saddle anesthesia. The patient had urinary incontinence and thoracic magnetic resonance imaging (MRI) showed an image of a mass compressing the medulla.

Cervical Epidural Hematoma after Chiropractic Spinal Manipulation Therapy in a Patient with an Undiagnosed Cervical Spinal Arteriovenous Malformation

Spinal epidural hematoma (SEH) occurring after chiropractic spinal manipulation therapy (CSMT) is a rare clinical phenomenon. Our case is unique because the patient had an undiagnosed cervical spinal arteriovenous malformation (AVM) discovered on pathological analysis of the evacuated hematoma. Although the spinal manipulation likely contributed to the rupture of the AVM, there was no radiographic evidence of the use of excessive force, which was seen in another reported case. As such, patients with a known AVM who have not undergone surgical intervention should be cautioned against symptomatic treatment with CSMT, even if performed properly. Regardless of etiology, SEH is a surgical emergency and its favorable neurological recovery correlates inversely with time to surgical evacuation.

Safety of cervical spine manipulation: are adverse events preventable and are manipulations being performed appropriately? A review of 134 case reports

BACKGROUND

Cervical spine manipulation (CSM) is a commonly utilized intervention, but its use remains controversial.

PURPOSE

To retrospectively analyze all available documented case reports in the literature describing patients who had experienced severe adverse events (AEs) after receiving CSM to determine if the CSM was used appropriately, and if these types of AEs could have been prevented using sound clinical reasoning on the part of the clinician.

DATA SOURCES

PubMed and the Cumulative Index to Nursing and Allied Health were systematically searched for case reports between 1950 and 2010 of AEs following CSM.

STUDY SELECTION

Case reports were included if they were peer-reviewed; published between 1950 and 2010; case reports or case series; and had CSM as an intervention. Articles were excluded if the AE occurred without CSM (e.g. spontaneous); they were systematic or literature reviews. Data extracted from each case report included: gender; age; who performed the CSM and why; presence of contraindications; the number of manipulation interventions performed; initial symptoms experienced after the CSM; and type of resultant AE.

DATA SYNTHESIS

Based on the information gathered, CSMs were categorized as appropriate or inappropriate, and AEs were categorized as preventable, unpreventable, or unknown. Chi-square analysis with an alpha level of 0.05 was used to determine if there was a difference in proportion between six categories: appropriate/preventable, appropriate/unpreventable, appropriate/unknown, inappropriate/preventable, inappropriate/unpreventable, and inappropriate/unknown.

RESULTS

One hundred thirty four cases, reported in 93 case reports, were reviewed. There was no significant difference in proportions between appropriateness and preventability, P = .46. Of the 134 cases, 60 (44.8%) were categorized as preventable, 14 (10.4%) were unpreventable and 60 (44.8%) were categorized as 'unknown'. CSM was performed appropriately in 80.6% of cases. Death resulted in 5.2% (n = 7) of the cases, mostly caused by arterial dissection.

LIMITATIONS

There may have been discrepancies between what was reported in the cases and what actually occurred, since physicians dealing with the effects of the AE, rather than the clinician performing the CSM, published many of the cases.

CONCLUSIONS

This review showed that, if all contraindications and red flags were ruled out, there was potential for a clinician to prevent 44.8% of AEs associated with CSM. Additionally, 10.4% of the events were unpreventable, suggesting some inherent risk associated with CSM even after a thorough exam and proper clinical reasoning.

Acute thoracic epidural hematoma following spinal manipulative therapy: case report and review of the literature

Spinal epidural hematoma is a rare complication of chiropractic manipulation. This study reports a case of thoracic spinal epidural hematoma following spinal manipulative therapy in the absence of predisposing factors. The effectiveness and safety of chiropractic treatment in chronic spinal pain and a literature review are also presented.

Spontaneous resolution of a traumatic cervicothoracic epidural hematoma presenting with transient paraplegia: a case report

STUDY DESIGN

Case description.

OBJECTIVE

To clinically and radiographically describe a traumatic spinal epidural hematoma (TSEH) without adjacent spinal column fracture or soft tissue injury that completely resolved, without surgical intervention.

SUMMARY OF BACKGROUND DATA

Symptomatic TSEH is an infrequent condition after spinal trauma, accounting for 0.5% to 1.7% of cases. It can result in permanent neurologic deficits if not treated in a timely and appropriate manner.

METHODS

A 50-year-old man presented with progressive lower motor weakness and sensory change at 2 days after blunt trauma to the upper back area. Neurologic examination revealed paraplegia and hypesthesia below the T4 sensory dermatome. Magnetic resonance imaging for cervicothoracic spine showed a space-occupying lesion in the dorsal spinal epidural space from C7 to T5. The lesion was consistent with acute stage hematoma of the spinal epidural space.

RESULTS

The patient was prepared for decompression surgery. However, the patient's neurologic symptoms began to improve (grade 4/5) at 2 hours after onset of paraplegia. Surgical intervention was delayed, and the patient was treated conservatively with close neurologic monitoring. Three days after onset of symptoms, the patient's neurologic symptoms recovered completely. The follow-up magnetic resonance imaging at 12 days after the event showed complete resolution of the epidural hematoma.

CONCLUSION

An unpredictable extensive epidural hematoma can occur after blunt trauma of the cervicothoracic spine in patients at low risk for hemorrhage. This case illustrates that immediate surgical intervention may not always be necessary in certain patients with TSEH. Conservative management with careful observation may play a role as a management option for patients initially presenting with severe neurologic dysfunction if neurologic recovery is early and sustained.

Cervical intradural disc herniation after spinal manipulation therapy in a patient with ossification of posterior longitudinal ligament: a case report and review of the literature

STUDY DESIGN

Case report and review of the literature.

OBJECTIVE

To report a patient presenting with Brown-Sequard syndrome due to cervical intradural disc herniation after spinal manipulation therapy.

SUMMARY OF BACKGROUND DATA

Spinal manipulation therapy (SMT) is often used by people with neck pain or discomfort as an alternative therapy due to its claimed less invasiveness and comparable efficacy. However, excessive manipulations are reported to cause rare but serious complications such as tetraplegia, vertebral artery dissection, epidural hematoma, and phrenic nerve injury.

METHODS

Clinical history, physical examination, and radiographic findings of the patient were described. Anterior cervical discectomy at the C3/C4 level and interbody fusion with a Caspar plate-screw system for fixation, were performed.

RESULTS

A favorable surgical outcome was obtained. The Brown-Sequard syndrome improved and the patient regained full muscle power at a 3-months follow-up.

CONCLUSION

Cervical intradural disc herniation after SMT is rare and most often cause Brown-Sequard syndrome. Definite diagnosis and prompt surgery usually achieves a satisfactory outcome. Anterior discectomy with interbody fusion is recommended. The OPLL associated with degenerative disc reminds us of the increased risk of intradural disc herniation. Those high-risk groups should be more cautious with spinal manipulation therapy due to its serious sequelae.

Cervical epidural hematoma after chiropractic spinal manipulation

Spinal epidural hematoma is a rare but potentially devastating complication of spinal manipulation therapy. This is a case report of a healthy pregnant female who presented to the emergency department with a cervical epidural hematoma resulting from chiropractic spinal manipulation therapy that responded to conservative treatment rather than the more common route of surgical management.

Spinal epidural hematoma after stretch exercise: a case report

Spinal epidural hematoma (SEH) is a rare but serious condition. Common causes of SEH include spinal fracture, spinal trauma, and invasive spinal procedures such as lumbar puncture, epidural anesthesia, or myelography. A few previous reports have suggested that SEH could be caused by minor triggers such as spinal manipulation therapy or spontaneously in rare cases. A 60-year-old man, immediately after stretch exercise, developed severe back cervicodynia and rapidly progressive weakness of left arm from SEH. He was treated by decompression laminectomy and evacuation of the hematoma. However, the upper extremity weakness did not completely resolve. The standard treatment remains timely surgical decompression and evacuation of the hematoma. Thus, early diagnosis and treatment can confer a significant prognostic advantage to patients with SEH. Based on the finding that SEH was caused by a mild mechanical trigger and neurologic deficits remained in this patient, this report highlights its diagnostic difficulty as well as the importance of rapid treatment. Emergency physicians should consider SEH among the differential diagnosis in patients with sudden-onset back pain with symptoms and signs of spinal cord compression.

Cervical myelopathy: a case report of a "near-miss" complication to cervical manipulation

OBJECTIVE

Cases have been reported in which radiculopathy or myelopathy secondary to herniated disk has occurred after cervical manipulation. In each case, it is not possible to determine whether the neurologic symptoms and signs were directly caused by the manipulation or whether they developed as part of the natural history of the disorder. The purpose of this article is to report a case in which a patient with radiculopathy secondary to herniated disk was scheduled to receive manipulation but just before receiving this treatment developed acute myelopathy.

CLINICAL FEATURES

A patient with arm pain and numbness was referred by a neurosurgeon for nonsurgical consult. He had a large C5-6 disk herniation with no signs or symptoms of myelopathy. He was determined to be a candidate for nonsurgical intervention, including manipulation. Manipulative treatment was planned for the second visit.

INTERVENTION AND OUTCOME

Ten days after the initial visit, and before any manipulative treatment being rendered, the patient developed symptoms suggestive of myelopathy, which were later determined on examination to be related to acute myelopathy secondary to the disk herniation.

CONCLUSION

Herniated disk in the cervical spine can progress to myelopathy as part of the natural history of this condition. Because of this, any interpretation of myelopathy that occurs after cervical manipulation, or any other procedure, must be made with caution.

Spinal epidural hematoma in a scoliotic patient with long fusion: a case report

BACKGROUND CONTEXT

This is the only reported case on a spinal epidural hematoma occurring in a fused scoliotic segment.

PURPOSE

To report the first case of a spinal epidural hematoma developed within the fused segment of a scoliotic curve and to raise clinicians' awareness of the pathology of a spinal epidural hematoma.

STUDY DESIGN/SETTING

A case report.

PATIENT SAMPLE

A 53-year-old woman with long spinal fusion for severe kyphoscoliosis diagnosed as a teenager.

OUTCOME MEASURES

Neurological improvement and clinical follow-up for any occult spinal fracture.

METHODS

A patient was surgically treated for a spinal epidural hematoma causing paraparesis. Clinical and radiological features were reported.

RESULTS

The etiology of this case could not be defined, although the patient had a minor fall injury. Radiography and computed tomography scans could not detect any obvious fracture. Magnetic resonance imaging showed typical features of an epidural hematoma. After the hematoma evacuation, the patient's neurology gradually improved.

CONCLUSIONS

Long fusion, differential stiffness along the fusion block, implant removal, and significant residual deformity may increase the risk of an epidural hematoma formation after trivial trauma without an obvious fracture on imaging. Clinicians should be mindful of this possibility and look out for any hematoma in the fused segment(s).

Spinal epidural hematoma after spinal manipulative therapy in a patient undergoing anticoagulant therapy: a case report

OBJECTIVE

We report on the case of a patient with spinal epidural hematoma (SEH) after spinal manipulative therapy and review features of reported cases of a similar nature.

CLINICAL FEATURES

The patient was undergoing Coumadin anticoagulant therapy for atrial fibrillation and presented to the chiropractor complaining of a stiff neck. After cervical manipulation, he developed paresthesia in both feet, progressing to motor deficits in all 4 extremities. He required a laminectomy and evacuation of a clot indenting the spinal cord.

RESULTS

Review of the literature revealed 7 reported cases of SEH after manipulation; 5 patients underwent cervical manipulation and 1 patient received Coumadin therapy.

CONCLUSION

Practitioners of spinal manipulative therapy should be aware of SEH as a possible complication of manipulation in patients at risk and should exercise caution in the care of patients undergoing anticoagulant therapy.

Ophthalmological adverse effects of (chiropractic) upper spinal manipulation: evidence from recent case reports

OBJECTIVE

Upper spinal manipulation (USM) is frequently used by chiropractors and other health care professionals to treat minor complaints. This systematic review aimed to summarize ophthalmological adverse effects of USM recently reported in the medical literature.

METHODS

Five electronic databases were searched for all case reports of ophthalmological adverse effects after USM published between January 1995 and April 2003. No language restrictions were applied. Key data from the primary publications thus located were extracted and critically evaluated.

RESULTS

Fourteen case reports were found. Clinical symptoms and signs were diverse and included loss of vision, ophthalmoplegia, diplopia and Horner's syndrome. The underlying mechanism was arterial wall dissection in most cases. The eventual outcome varied and often included permanent deficits. Causality was frequently deemed likely or certain.

CONCLUSION

Upper spinal manipulation is associated with ophthalmological adverse effects of unknown frequency. Ophthalmologists should be aware of its risks. Rigorous investigations must be conducted to establish reliable incidence figures.

Spontaneous spinal epidural hematoma: A case report

A 59-year-old man presented to the emergency department (ED) the day after a minor motor vehicle crash for evaluation of bilateral shoulder pain. He underwent ED evaluation for his back pain two more times before it was found that he had a spontaneous spinal epidural hematoma (SSEH). On the third visit, the patient had waxing and waning neurologic symptoms including lower extremity weakness and urinary retention. The diagnosis was made by MRI, and the patient was successfully treated with cervical hemilaminectomy at the cervicothoracic junction for evacuation of the epidural hematoma 5 days after the onset of back pain.

Delayed traumatic spinal epidural hematoma with spontaneous resolution of symptoms

Post-traumatic spinal epidural hematomas are uncommon, usually requiring emergent neurosurgical evacuation. We present a symptomatic delayed post-traumatic epidural hematoma of the T-spine that resolved within hours of administration of high dose steroids. A 22-year-old man presented 10 days after sustaining blunt trauma during a motor vehicle crash. He developed signs of acute cord compression with loss of sensation and motor function in bilateral lower extremities with priapism. Magnetic resonance imaging demonstrated a spinal epidural hematoma with 50% canal stenosis at the T4 level. His symptoms improved 1 h after the administration of high dose steroids. All symptoms resolved completely while the patient was in the Emergency Department and he was treated conservatively by Neurosurgery with no further sequelae. Thoracic spinal epidural hematoma is an uncommon condition that may present in delayed fashion after trauma with significant neurologic compromise. If neurologic symptoms improve with initial steroid therapy, patients with this condition may be treated conservatively with steroids and observation.
