Cervical spine TB - Current concepts in management

Cervical tuberculosis treated with closed system abscess evacuation, and percutaneous laser disc decompression combined with secretome derived from umbilical cord mesenchymal stem cells: A case report

INTRODUCTION AND IMPORTANCE

Minimal invasive surgery is preferred as it offers the same benefit with less tissue damage, especially in the cervical area where a lot of critical structure resides. Mesenchymal stem cells (MSCs) and its secretome provide a promising regenerative intervention to damaged tissue. We report a cervical spinal tuberculosis case with hemiparesis treated with minimally invasive surgery combined with a regenerative approach.

CASE PRESENTATION

A 13-year-old boy presented with weakness in his left arm and left leg, accompanied by hemiparesthesia. The patient was unable to get up from bed, run, and jumpRadiology examination showed compression fracture, intervertebral disc retropulsion, spinal cord compression, and paravertebral cold abscess. The patient was treated with a single minimal invasive surgery consisting of closed system abscess evacuation, and percutaneous laser disc decompression combined with umbilical cord-derived mesenchymal stem cells.

CLINICAL DISCUSSION

The pain, weakness, and numbness were gone two days after surgery. The patient could carry out normal activities, even doing sports such as mini soccer and badminton. This clinical improvement was obtained as he carried out some procedures. The cold abscess aspiration removed infection focus which prevents further vertebra destruction, PLDD which decompresses the retropulsed discs, and implantation of MSCs and secretomes which regenerate and strengthen the destructed bone and surrounding tissue.

CONCLUSION

Closed system abscess evacuation, and percutaneous laser disc degeneration combined with secretome derived from UC-MSC are minimally-invasive strategies with promising results. Further studies are required to investigate its efficacy.

Imaging Assessment of Nontraumatic Pathologic Conditions at the Craniovertebral Junction: A Comprehensive Review

Nontraumatic pathologic conditions of the craniovertebral junction encompass a range of conditions affecting the complex anatomy of this region without direct physical injury. These conditions include congenital syndromes that predispose individuals to ligamentous laxity, potentially leading to instability. Additionally, rare but noteworthy cases such as Grisel syndrome, a cause of pediatric torticollis, may arise without a traumatic trigger. Inflammatory diseases, including rheumatoid arthritis, ankylosing spondylitis, and crystal deposition, can lead to cervical instability and spinal cord compression. Infections at the upper cervical spine are dominated by tuberculosis, typically transmitted through hematologic or lymphatic routes with characteristic imaging findings. On the other hand, purulent bacterial infections in this area are rare. Furthermore, although tumors involving the structures of the craniovertebral junction are infrequent, they can lead to significant complications, albeit less frequently through cord compression and more commonly via pathologic fractures or subluxation. The craniocervical junction is a complex anatomic region comprising ligaments, bones, joints, and muscles that support the head's weight and enable its wide range of motion. Accurate recognition and understanding of the complex anatomy and the various nontraumatic pathologic conditions at the craniovertebral junction are pivotal for initiating timely and appropriate treatment strategies. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Stabilizing the unstable: Tuberculosis of the odontoid process with atlanto-occipital instability-Case report and review of literature

Key Clinical Message

Tuberculosis (TB) of the odontoid process is a rare but potentially, a debilitating condition. Surgical intervention, in the form of stabilizing the spine and decompressing the spinal cord, offers a tailored approach to managing this condition effectively and improving prognosis.

Abstract

Odontoid process tuberculosis (TB) is a rare condition that can cause spinal instability and neurological complications. Diagnosis of odontoid process TB is difficult and requires a combination of clinical, radiographic, and histopathological examinations. This report describes the treatment of a 46-year-old female with quadriparesis and intermittent fever. Radiological findings showed TB of the odontoid process with atlanto-axial dislocation causing compressive myelopathy. She underwent C1-C3 decompressive laminectomy and stabilization from C1 to C5. GeneXpert for TB was positive and she was started on anti-tuberculous medications. She regained power gradually and at 1 year follow-up she was ambulant without any support. The C1-C5 lateral mass screw and C1-C3 decompressive laminectomy approach, as highlighted in this case, offers an effective solution, enhancing patient quality of life, and preventing disease progression.

Preoperative Skull Traction, Anterior Debridement, Bone Grafting, and Internal Fixation for Cervical Tuberculosis with Severe Kyphosis

OBJECTIVE

Cervical tuberculosis (CTB) readily causes local kyphosis, and its surgical strategy remains controversial. Although some previous studies suggested that the anterior approach could effectively treat CTB, patients in these studies only suffered mild to moderate kyphosis. Therefore, little is known about whether the anterior approach can achieve satisfactory outcomes in CTB patients with severe kyphosis. This study was performed to evaluate the safety and efficacy of preoperative skull traction combined with anterior surgery for the treatment of CTB patients with a severe kyphosis angle of more than 35°.

METHODS

In this retrospective study, we enrolled 31 CTB patients with severe kyphosis who underwent preoperative skull traction combined with anterior surgery from April 2015 to January 2021. Patients were followed up for at least 2 years. Clinical data, such as operative time, blood loss, and postoperative hospital stay, were collected. The clinical outcomes included American Spinal Injury Association (ASIA) spinal cord injury grade, Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score, and related complications. The radiological outcomes included the Cobb angle of cervical kyphosis at each time point and the bony fusion state. Clinical efficacy was evaluated by paired Student's t-test, Mann-Whitney U-test, and others.

RESULTS

Six patients had involvement of one vertebra, 21 had involvement of two vertebrae, and four had involvement of three vertebrae. The most common level of vertebral involvement was C4-5, whereas the most common apical vertebra of kyphosis was C4. The mean kyphosis angle was 46.1° ± 7.7° preoperatively, and the flexibility on dynamic extension-flexion X-rays and cervical MRI was 17.5% ± 7.8% and 43.6% ± 11.0%, respectively (p = 0.000). The kyphosis angle significantly decreased to 13.2° ± 3.2° after skull traction, and it further corrected to -6.1° ± 4.3° after surgery, which was well maintained at the final follow-up with a mean Cobb angle of -5.4° ± 3.9°. The VAS and JOA scores showed significant improvement after surgery. The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels normalized at 3 months after surgery. All patients achieved solid bone fusion, and no complications related to the instrumentation or recurrence were observed.

CONCLUSION

Preoperative skull traction combined with anterior debridement, autologous iliac bone grafting, and internal plate fixation can be an effective and safe surgical method for the treatment of cervical tuberculosis with severe kyphosis. Skull traction can improve the safety and success rate of subsequent anterior corrective surgery.

Anterior debridement combined with autogenous iliac bone graft fusion for the treatment of lower cervical tuberculosis: a multicenter retrospective study

BACKGROUND

This study aimed to analyze the clinical efficacy of one-stage anterior debridement of lower cervical tuberculosis using iliac crest bone graft fusion and internal fixation.

MATERIALS AND METHODS

A retrospective analysis was performed on 48 patients with lower cervical tuberculosis admitted to multiple medical centers from June 2018 to June 2021. Among them, 36 patients had lesions involving two vertebrae and 12 patients had lesions involving more than three vertebrae. All patients were treated with quadruple antituberculosis drugs for more than 2 weeks before the operation, and then treated with one-stage anterior debridement and autogenous iliac bone graft fusion combined with titanium plate internal fixation. After the operation, antituberculosis drugs were continued for 12-18 months. The patients were followed-up to observe the improvement in clinical symptoms, bone graft fusion, Cobb angle, visual analog score (VAS), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), wound healing, and neurological function.

RESULTS

The patients were followed-up for 13-43 months, with an average of 21.46 ± 1.52 months. The clinical symptoms significantly improved after the operation. The bone graft was completely fused in all patients, and the bone fusion time was 3-6 months, with an average of 4.16 ± 0.47 months. At the last follow-up, the Cobb angle, VAS, ESR, and CRP level were significantly lower than those before surgery (P < 0.05). None of the patients had loosening, detachment, or rupture of the internal fixation, and no recurrence occurred. All surgical incisions healed in one stage without infection or sinus formation. The preoperative Frankel neurological function classification was grade B in 7 cases, grade C in 13, grade D in 18, and grade E in 10. At the last follow-up, 8 cases recovered to grade D and 40 recovered to grade E.

CONCLUSIONS

For patients with lower cervical tuberculosis, based on oral treatment with quadruple antituberculosis drugs, direct decompression through anterior debridement, followed by autologous iliac bone graft fusion combined with internal fixation can completely remove tuberculosis foci, rebuild the stability of the cervical spine, and obtain good clinical efficacy. Level of evidence Level 3.

The Incidence, Changes and Treatments of Cervical Deformity After Infection and Inflammation

A healthy cervical spine with normal movement is the basis of many daily activities and is essential for maintaining a good quality of life. However, the alignment, fusion, and structure of the cervical spine can change for various reasons, leading to cervical deformity, mainly kyphosis. Approximately 5%‒20% of spinal infections in the cervical spine cause cervical deformity. The deformity can recover early; however, the disease's long-term existence or the continuous action of abnormal stress may lead to intervertebral fusion and abnormal osteophytes. Many gaps and controversies exist regarding infectious cervical deformities, including a lack of clear definitions and an acceptable classification system thereby requiring further research. Moreover, there is no consensus on the indications for postinfectious cervical deformity associated with <i>Mycobacterium tuberculosis</i>, <i>Staphylococcus aureus</i>, and Brucellosis. Therefore, we reviewed and discussed the incidence, clinical manifestations, changes, and treatment of infectious and inflammatory secondary cervical deformities from common to rare to provide a theoretical basis for clinical decision-making.

Improving functional outcomes and quality of life in an elderly woman with sarcopenia and spinal Tuberculosis: A case report

Background

Indonesia is the world's second-largest contributor to TB patients. According to prevalence by age, the elderly have the most diagnosed TB. In Indonesia, TB spondylitis affects approximately 5% of TB cases and is a common cause of non-traumatic spinal cord injury (NTSCI). Spinal cord injury (SCI) is a growing public health concern, particularly among the elderly, as many of its populations have sarcopenia. Due to the complete absence of voluntary muscle contraction, SCI is followed by a rapid loss of skeletal muscle mass. SCI has several physical, psychological, social, and economic consequences.

Case presentation

A 68-years-old woman presented with weakness and numbness of all four limbs. She also had sarcopenia, malnutrition, and dependency on activities of daily living (ADL). In addition, the patient was at a risk of SCI complications. Magnetic resonance imaging (MRI) showed destruction of the vertebral bodies at the level of the 5th and 6th cervical area, tuberculous abscesses of the paravertebral and longus colli muscles. The patient underwent debridement and spinal stabilization. However, the patient was at a risk of developing SCI complications. In these patients, the Physical Rehabilitation and Medicine (PRM) strategy focuses on improving medical conditions, including preventing secondary complications, promoting neurological recovery, and optimizing function.

Conclusion

This case highlights the importance of PRM intervention in assessing functional disorders in the elderly to improve their quality of life (QOL).

Isolated Tuberculosis of the Cervical Vertebrae

Tuberculosis (TB) is a highly infectious disease that primarily affects the lungs, but extrapulmonary affection can occur with lymphatic or hematogenous spread. Skeletal affection commonly involves the spine, but cervical vertebral affection is rare. We report a 23-year-old female patient who presented to the hospital with diffuse limb weakness and neck pain as the only complaints. MRI of the cervical spine revealed a peripherally enhancing lesion arising from the posterior aspects of the cervical vertebrae with compressive myelopathy. She underwent surgical decompression and was noted to have caseous drainage during the procedure. She was started promptly on anti-tuberculous therapy after she had a positive interferon-gamma release assay. Late culture results confirmed isolated cervical TB of the vertebrae as the diagnosis. Prompt awareness and initiation of treatment for vertebral TB are necessary as clinical presentation can mimic other infectious and malignant etiologies.

Rapid Deterioration of a Cervical Tuberculosis Disease in a Young Immunocompetent Patient: A Case Report

Any organ system is prone to extrapulmonary tuberculosis (EPTB) development, including the spine. Spinal TB is a rare involvement, although considered one of the most dangerous forms of skeletal TB (STB).

A 31-year-old man, who is a healthcare worker, presented to the outpatient Orthopedic Spine clinic at King Abdulaziz Medical City-Ministry of National Guard Health Affairs (KAMC-MNGHA) Jeddah, Saudi Arabia, with a complaint of axial neck and upper back pain whose condition deteriorated quickly, necessitating urgent admission for surgical treatment in the form of cervical spine decompression and fusion, in addition to the anti-tuberculosis drug (ATD) scheme.

Cervical TB is a rare spinal disease that supposedly has a slow, insidious progression. The main presenting symptoms of which are axial and/or radicular pain, with a possible neurological deficit(s). In this particular case, the rapid progression of the disease necessitated rapid action.

In spite of what is known about spine TB and its slow progression, the case presented here was beyond our expectations. Treatment planning and urgency should not rely on the known natural history of the disease but rather be tailored to each case individually. This delineates the importance of reporting the quick, unexpected deterioration of our patient’s condition.

Functional outcomes in the management of cervicothoracic junction tuberculosis

Background

We analyzed the clinical and radiological parameters influencing functional outcomes and neurological recovery in patients with cervicothoracic junctional tuberculosis (TB).

Methods

This was a retrospective analysis of 16 cases of cervicothoracic junction (CTJ) spinal TB; 11 patients were managed operatively, while five were managed conservatively. Patients' outcomes were assessed at 1 month, 1 year, and yearly thereafter and included an analysis of multiple outcome scores, various radiographic parameters, and sensitivity or resistance to anti-tubercular therapy.

Results

Patients averaged 25.94 years of age, and typically had three-level vertebral involvement. They were followed for a mean duration of 24 months, and the duration of anti-tubercular therapy averaged 17 months. Patients demonstrated clinical improvement on Japanese Orthopedic Association score and Neck disability index (P < 0.005) starting from 1 month following initiation of treatment which continued in subsequent follow-up, along with change in radiological parameters consisting of mean segmental kyphotic angle from 18.98° to 15.13°, C2-C7 SVA from 16.13 mm to 22.61 mm, T1 slope from 22.80° to 14.66°, thoracic inlet angle from 75.35° to 63.25°, neck tilt from 51.81° to 48.33°, and cervical lordosis from 4.66° to -0.44° (P > 0.05) at the end of 1 year.

Conclusion

Tuberculous affection of the dynamic CTJ is a challenging scenario in clinical practice and its management involves consideration of disease extent, neurological status, and effort toward restoration of normal alignment of spine in sagittal and coronal plane to get favorable clinical outcomes.

Efficacy of anterior debridement and bone grafting with fusion using internal fixation combined with anti-tuberculosis chemotherapy in the treatment of subaxial cervical tuberculosis

Background

To evaluate the efficacy of anterior debridement and bone grafting with fusion using internal fixation (BFIF) combined with anti-tuberculosis chemotherapy in the treatment of subaxial cervical spine tuberculosis (SCS-TB).

Methods

Clinical and radiographic data of patients with SCS-TB treated by anterior debridement and BFIF at our hospital from January 2010 to December 2017 were analyzed retrospectively. The SCS sagittal parameters at the preoperative, postoperative, and final follow-up were documented and compared, including the Occiput-C2 angle, C2–C7 Cobb angle, local Cobb angle, spinal canal angle (SCA), C2–C7 sagittal vertical axis (C2–C7 SVA), the center of gravity of the head-C7 sagittal vertical axis (CGH-C7 SVA), T1 slope (T1S), neck tilt (NT), and thoracic inlet angle (TIA). The ASIA grade, NDI index, JOA score, and VAS score were utilized to assess the postoperative function recovery, and the complications were recorded.

Results

A total of 23 patients were included in the study with a mean age of 46.74 ± 15.43 years, including 8 males and 15 females. All patients with SCS-TB were treated with anterior debridement and BFIF, with a mean postoperative follow-up time of 37.17 ± 12.26 months. The poisoning symptoms of TB were relieved in all patients, and ESR (42.09 ± 9.53 vs 8.04 ± 5.41, P < 0.05) and CRP (30.37 ± 16.02 vs 7.4 ± 2.68, P < 0.05) were decreased at the 3 postoperative months in the comparison of the preoperative. The C0–C2 Cobb angle, C2–C7 Cobb angle, local Cobb angle, SCA, TIS, C2–C7 SVA, and CGH-C7 SVA were corrected remarkably after surgery (P < 0.05). Further, there was a significant improvement in the JOA, VAS, and NDI with the comparison of the preoperative (P < 0.05).

Conclusions

Anterior debridement and BFIF combined with anti-TB chemotherapy was a practical tool for the treatment of SCS-TB with the help of SCS sagittal parameters, which can remove the lesion completely, decompress the spinal cord compression, and correct the kyphotic deformity to restore the spine sagittal balance.

Tuberculous Abscesses in the Head and Neck Region

Tuberculosis represents a global health challenge and is one of the leading infectious killers, with over a million people succumbing to it every year. While the disease is primarily prevalent in developing countries, where 95% of cases and deaths occur, doctors around the globe need to be able to recognize its diverse clinical manifestations in order to initiate appropriate treatment early. The granulomatous infection caused by Mycobacterium tuberculosis typically affects the lungs, but isolated abscesses in the head and neck region can be a less common presentation of the disease, potentially resulting in dysphagia, odynophagia, voice changes, neck swelling, bone erosion, and even life-threatening respiratory distress requiring tracheostomy. Here, characteristic imaging findings and potential surgical options are discussed.

Life-threatening disseminated tuberculosis masquerading as cervical spondylosis--- Case report “Cervical TB v/s Cervical Spondylosis”

Tuberculosis (TB) is quite prevalent in developing countries, with an ever-rising incidence of extrapulmonary cases. TB of bones and joints is quite challenging to diagnose. Most spinal TB lesions localize at the thoracic and lumbar levels; cervical lesions are a rarity. Hence, most neck pains are labelled cervical spondylosis as the symptomatology of cervical spine tuberculosis (CTB) remains unclear. A 38-year-old male had long-standing neck pain for six months, not associated with any focal neurological deficit, nausea, vomiting, or blurred vision. After the initial evaluation by local practitioners, the pain was, as usual, attributed to cervical spondylosis and conservatively managed. However, his pain worsened, and he ultimately came to us with altered mental status. In reality, he had CTB, which later complicated to life-threatening disseminated TB with intracranial and pulmonary involvement, and he could only survive after prolonged ICU care. Even mild cervical pain should not be neglected and must undergo proper evaluation. We should consider CTB in the differential diagnosis of chronic neck pain, especially in countries where TB is endemic.
