Abstract
STUDY DESIGN Systematic Review and Meta-analysis. OBJECTIVE The purpose of this study is to synthesize recommendations for perioperative medical management of RA patients and quantify outcomes after spine surgery when compared to patients without RA. METHODS A search of available literature on patients with RA and spine surgery was performed. Studies were included if they provided a direct comparison of outcomes between patients undergoing spine surgery with or without RA diagnosis. Meta-analysis was performed on operative time, estimated blood loss, hospital length of stay, overall complications, implant-related complications, reoperation, infection, pseudarthrosis, and adjacent segment disease. RESULTS Included in the analysis were 9 studies with 703 patients with RA undergoing spine surgery and 2569 patients without RA. In RA patients compared to non-RA patients undergoing spine surgery, the relative risk of infection was 2.29 times higher (P = .036), overall complications 1.61 times higher (P < .0001), implant-related complications 3.93 times higher (P = .009), and risk of reoperation 2.45 times higher (P < .0001). Hospital length of stay was 4.6 days longer in RA patients (P < .0001). CONCLUSIONS Treatment of spinal pathology in patients with RA carries an increased risk of infection and implant-related complications. Spine-specific guidelines for perioperative management of antirheumatic medication deserve further exploration. All RA patients should be perioperatively co-managed by a rheumatologist. This review helps identify risk profiles in RA specific to spine surgery and may guide future studies seeking to medically optimize RA patients perioperatively.

Risk factor analysis of perioperative complications in patients with rheumatoid arthritis undergoing primary cervical spine surgery. Arthritis Res Ther 2022; 24:79. [PMID: 35361268 PMCID: PMC8969231 DOI: 10.1186/s13075-022-02767-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Accepted: 03/18/2022] [Indexed: 11/20/2022] Open
Abstract
Background Rheumatoid arthritis (RA) often causes cervical spine lesions as the disease condition progresses, which induce occipital neuralgia or cervical myelopathy requiring surgical interventions. Meanwhile, patients with RA are susceptible to infection or other complications in the perioperative period because they frequently have comorbidities and use immunosuppressive medications. However, the risk factors or characteristics of patients with RA who experience perioperative complications after cervical spine surgery remain unknown. A risk factor analysis of perioperative complications in patients with RA who underwent primary cervical spine surgery was conducted in the present study. Methods A total of 139 patients with RA who underwent primary cervical spine surgery from January 2001 to March 2020 were retrospectively investigated. Age and height, weight, serum albumin, serum C-reactive protein, American Society of Anesthesiologists Physical Status (ASA-PS), Charlson comorbidity index, medications used, cervical spine lesion, surgery time, bleeding volume, and procedures were collected from medical records to compare the patients with complications to those without complications after surgery. The risk factors for perioperative complications were assessed by univariate and multivariate logistic regression analysis. Results Twenty-eight patients (20.1%) had perioperative complications. Perioperative complications were significantly associated with the following factors [data presented as odds ratio]: lower height [0.928, p=0.007], higher ASA-PS [2.296, p=0.048], longer operation time [1.013, p=0.003], more bleeding volume [1.004, p=0.04], higher rates of vertical subluxation [2.914, p=0.015] and subaxial subluxation (SAS) [2.507, p=0.036], occipito-cervical (OC) fusion [3.438, p=0.023], and occipito-cervical/thoracic (long) fusion [8.021, p=0.002] in univariate analyses. In multivariate analyses, lower height [0.915, p=0.005], higher ASA-PS [2.622, p=0.045] and long fusion [7.289, p=0.008] remained risk factors. High-dose prednisolone use [1.247, p=0.028], SAS [6.413, p=0.018], OC fusion [17.93, p=0.034], and long fusion [108.1, p<0.001] were associated with severe complications. Conclusions ASA-PS and long fusion could be indicators predicting perioperative complications in patients with RA after cervical spine surgery. In addition, cervical spine lesions requiring OC fusion or long fusion and high-dose prednisolone use were suggested to be risk factors for increasing severe complications.

Abstract
In the United States, 100,000-300,000 patients die from venous thromboembolism (VTE) each year, with more than 500,000 people related hospitalizations. While in Europe, 500,000 people die from VTE each year. Patients with rheumatoid arthritis are at increased risk of VTE. The use of biologics in patients with rheumatoid arthritis may be associated with an increased risk of VTE. We identified all patients who had been newly approved for Catastrophic Illness Card of rheumatoid arthritis extracted the claims data from the National Health Insurance research database and Registry for Catastrophic Illness Patient Database from 2003 to 2016. VTE was defined as the presence of inpatient VTE diagnostic codes (including DVT or PE) according to the discharge diagnosis protocol. An analysis of VTE variables indicated that the incidence of VTE in the biologic group (14.33/10,000 person-years) was higher than that in the conventional drug group (12.61/10,000 person-years). As assessed by the Cox proportional hazards model, the relative HR for VTE in the biologic group (HR: 1.11; 95% CI 0.79-1.55) versus that in the conventional drug group did not reach a significant difference. In conclusion, this study found no significant differences in risk were observed between the use of conventional DMARDs and biologics.

Comparison of adult spinal deformity patients with and without rheumatoid arthritis undergoing primary non-cervical spinal fusion surgery: a nationwide analysis of 52,818 patients. Spine J 2018; 18:1861-1866. [PMID: 29631060 DOI: 10.1016/j.spinee.2018.03.020] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2017] [Revised: 01/25/2018] [Accepted: 03/26/2018] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Numerous studies have analyzed the impact of rheumatoid arthritis (RA) on the cervical spine and its related surgical interventions. However, there is a paucity of literature available conducting the same analyses in patients with non-cervical spine involvement. PURPOSE The objective of this study was to compare patient characteristics, comorbidities, and complications in patients with and without RA undergoing primary non-cervical spinal fusions. STUDY DESIGN/SETTING This is a retrospective national database review. PATIENT SAMPLE A total of 52,818 patients with adult spinal deformity undergoing non-cervical spinal fusions (1,814 patients with RA and 51,004 patients without RA). OUTCOME MEASURES The outcome measures in the study include patient characteristics, as well as complication and mortality rates. MATERIALS AND METHODS Using the Nationwide Inpatient Sample from 2003 to 2014, International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis and procedure codes were used to identify patients aged ≥18 years old with and without RA undergoing primary non-cervical spinal fusions. Univariate analysis was used to determine patient characteristics, comorbidities, and complication values for each group. Bivariate analysis was used to compare the two groups. Significance was set at p<.05. RESULTS Patients with RA were older (p<.001), were more likely to be women (p<.001), had increased rates of osteoporosis (p<.001), had a greater percentage of their surgeries reimbursed by Medicare (p<.001), and more often had weekend admissions (p=.014). There was no difference in all the other characteristics. Patients with RA had higher rates of iron deficiency anemia, congestive heart failure, chronic pulmonary disease, depression, and fluid and electrolyte disorders (all, p<.001). Patients without RA had higher rates of alcohol abuse (p=.027). There was no difference in all the other complications. There was no difference in mortality rate (p=.99). Total complications were greater in patients with RA (p<.001). Patients with RA had higher rates of infection (p=.032), implant-related complications (p=.010), incidental durotomies (p=.001), and urinary tract infections (p<.001). No difference existed among the other complications. CONCLUSIONS Patients with RA have an increased number of comorbidities and complication rates compared with patients without RA. Such knowledge can help surgeons and patients with RA have beneficial preoperative discussions regarding outcomes.

Risk Factors for the Development and Progression of Atlantoaxial Subluxation in Surgically Treated Rheumatoid Arthritis Patients, Considering the Time Interval between Rheumatoid Arthritis Diagnosis and Surgery. J Korean Neurosurg Soc 2016; 59:590-596. [PMID: 27847572 PMCID: PMC5106358 DOI: 10.3340/jkns.2016.59.6.590] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2016] [Revised: 08/26/2016] [Accepted: 08/30/2016] [Indexed: 01/29/2023] Open
Abstract
Objective Rheumatoid arthritis (RA) is a systemic disease that can affect the cervical spine, especially the atlantoaxial region. The present study evaluated the risk factors for atlantoaxial subluxation (AAS) development and progression in patients who have undergone surgical treatment. Methods We retrospectively analyzed the data of 62 patients with RA and surgically treated AAS between 2002 and 2015. Additionally, we identified 62 patients as controls using propensity score matching of sex and age among 12667 RA patients from a rheumatology registry between 2007 and 2015. We extracted patient data, including sex, age at diagnosis, age at surgery, disease duration, radiographic hand joint changes, and history of methotrexate use, and laboratory data, including presence of rheumatoid factor and the C-reactive protein (CRP) level. Results The mean patient age at diagnosis was 38.0 years. The mean time interval between RA diagnosis and AAS surgery was 13.6±7.0 years. The risk factors for surgically treated AAS development were the serum CRP level (p=0.005) and radiographic hand joint erosion (p=0.009). The risk factors for AAS progression were a short time interval between RA diagnosis and radiographic hand joint erosion (p<0.001) and young age at RA diagnosis (p=0.04). Conclusion The CRP level at RA diagnosis and a short time interval between RA diagnosis and radiographic hand joint erosion might be risk factors for surgically treated AAS development in RA patients. Additionally, a short time interval between RA diagnosis and radiographic hand joint erosion and young age at RA diagnosis might be risk factors for AAS progression.

Abstract
Rheumatoid arthritis (RA) is the most common inflammatory disease of the cervical spine (CS). After hands and feet, CS is the most commonly involved segment, being present in more than half of the patients with RA. Especially in the CS, RA may cause degeneration of ligaments, leading to laxity, instability and subluxation of the vertebral bodies. This is often asymptomatic or symptoms are erroneously attributed to peripheral manifestations. Otherwise, this may cause compression of spinal cord (SC) and medulla oblongata leading to severe neurologic deficits and even sudden death. Owing to its potentially debilitating and life-threatening sequelae, inevitable progression once neurologic deficits occur and the poor medical condition of afflicted patients, CS involvement remains a priority in the diagnosis and its treatment will remain a challenge. The surgical approach aims a solid fixation of the upper cervical spine, giving stability, preventing neurologic deterioration and injury to the SC, leading to improved neurologic function, vascular integrity and maintenance of sagittal balance. The recent advances in surgical techniques, complete understanding of the anatomy and precise preoperative evaluation led to safer and more effective procedures that have decreased complication rates. Based on the fact that when a patient becomes myelopathic the rate of long-term mortality increases and the chance of neurologic recovery decreases, many authors agree that early surgical intervention, before the onset of neurologic deficits, gives a more satisfactory outcome. However, the timing when a prophylactic stabilization should occur is poorly defined, and so, patients with radiographic instability but without evidence of neurologic deficit are still the most difficult to manage.

Abstract
Myelopathy is a form of neurological disease caused by compression of the spinal cord. Upper and lower quarter screens are commonly used in identifying myelopathy, although most of the screen components demonstrate poor or unstudied diagnostic value. The purpose of this case report is to describe the diagnostic process in detecting syringomyelia, an intramedullary lesion that may cause myelopathy. The patient was a 47-year-old female with a thoracic syrinx that was discovered by spinal magnetic resonance imaging (MRI) following a complicated and delayed clinical diagnostic course. Following surgical intervention and a two-week inpatient rehabilitation stay, the patient was discharged using a rolling walker for ambulation and was performing most transfers with modified independence. A complicating pattern of signs and symptoms combined with a diagnostic process guided by poorly studied screen components demonstrates the diagnostic dilemma associated with identifying the cause of myelopathy within the thoracic spine. This also indicates the need for further investigation of individual and clustered components of the neurological screen to improve the ability to identify patients in need of complete imaging studies in a more timely fashion.

Abstract
OBJECTIVE Rheumatoid arthritis commonly involves the upper cervical spine and can cause significant neurologic morbidity and mortality. However, there is no consensus on the optimal timing for surgical intervention: whether surgery should be performed prophylactically or once neurologic deficits have become apparent. METHODS A systematic review of the literature was performed to analyze neurologic outcome (Ranawat) and survival time (Kaplan-Meier) after surgical or conservative treatment using the MOOSE (Meta-analysis Of Observational Studies in Epidemiology) and GRADE (Grading of Recommendations, Assessment, Development and Evaluation system) criteria. RESULTS Twenty-five observational studies were selected. No randomized controlled trials (RCTs) could be found. All of the studies had a high risk of bias. Twenty-three studies reported the neurologic outcome after surgery for 752 patients. Neurologic deterioration rarely occurred in Ranawat I and II patients. Ranawat III patients did not fully recover. The 10-year survival rates were 77%, 63%, 47%, and 30% for Ranawat I, II, IIIA, and IIIB, respectively. The Ranawat IIIB patients had a significantly worse outcome. Another 185 patients treated conservatively were described in 7 studies. Neurologic deterioration rarely occurred in Ranawat I patients, but was almost inevitable in Ranawat II, IIIA, and IIIB patients. The Kaplan-Meier analysis showed a 10-year overall survival rate of 40%. CONCLUSION There are no RCTs that compared surgery with conservative treatment. In observational studies, surgical neurologic outcomes were better than conservative treatment in all patients with cervical spine involvement, and in asymptomatic patients with no neurologic impairment (Ranawat I) the outcomes were similar; however, the evidence is weak. Survival time of surgical and conservative treatment could not be compared.

Abstract
OBJECTIVE To evaluate the correlation between neurological deficits indicative of compressive myelopathy and MRI findings in a series of patients with RA and symptomatic involvement of the cervical spine. METHODS Forty-one consecutive patients with RA were studied using cervical spine MRI. Unconditional logistic regression analysis was used to identify MRI parameters of cervical spine involvement associated with the development of neurological dysfunction. RESULTS The mean age of the 41 patients (33 women and 8 men) was 59 yrs (range 23-82 yrs), while the median disease duration was 18 +/- 9 yrs (range 4-40 yrs). According to Ranawat's classification, 17 (42%) patients were in Class I, 21 (51%) in Class II and 3 (7%) in Class III. Thus, patients with clinical manifestations of compressive myelopathy (Ranawat's Class II + III) represented 58% (24/41) of all cases. Among the different MRI parameters of cervical spine involvement analysed, only the presence of atlantoaxial spinal canal stenosis [odds ratio (OR) 4.55; 95% CI 1.14-18.15], atlantoaxial cervical cord compression (OR 9.6; 95% CI 1.08-85.16) and subaxial myelopathy changes (OR 11.43; 95% CI 1.3-100.81) were associated with a significantly increased risk for neurological dysfunction (Ranawat's Class II or III). CONCLUSION In RA patients with symptomatic cervical spine involvement, there is a strong correlation between the development of neurological dysfunction and MRI identification of atlantoaxial spinal canal stenosis, especially in those cases with evidence of upper cervical cord or brainstem compression and subaxial myelopathy changes.

Abstract
We present the occurrence and management of mediastinal migration of the distal aspect of a posterior occipito-thoracic screw-rod construct. No similar occurrence was found in the literature. This event occurred following an emergency tracheotomy (requiring neck hyperextension) in a patient with severe rheumatoid arthritis, who had previously undergone decompression and an Occiput-T2 instrumented fusion for cranio-cervical and sub-axial cervical spine instability. Imaging showed fracture-subluxation of T1/2 and T2/3 with the bilateral C7, T1 and T2 screws in the mediastinum causing tracheal and esophageal compression. Removal of the instrumentation, decompression (T2 corpectomy) and construct revision down to T10 was safely performed from a posterior approach. Severe osteoporosis, some pre-existing screw loosening and hyperextension of the neck were the predisposing factors of this near catastrophic event. By staying directly posterior to the rod and following the fibrous tract already created, the instrumentation was safely removed from the mediastinum.

Abstract
Cervical deformities arise from a multitude of causes, including genetic, congenital, inflammatory, degenerative, and iatrogenic etiologies. They often require surgical intervention for treatment of pain, progressive structural decompensation, and neurologic deterioration. Although congenital and hereditary causes of cervical deformity require specialized attention to particular clinical features and operative considerations, postsurgical (iatrogenic) cervical deformity after surgery is the most common single cause. Appropriate treatment involves careful selection of conservative and aggressive measures and familiarity with advanced surgical techniques that allow for the safe correction of these challenging deformities. Flexible deformities can be managed with single-staged procedures, whereas fixed deformities require two-staged or even three-staged procedures. Staged surgery for fixed cervical deformities can achieve up to 28 degrees of angular correction and 31% translational correction.

Abstract
OBJECTIVE Rheumatoid arthritis frequently affects the craniovertebral junction (CVJ) and may lead to severe neck pain, quadriparesis, and respiratory dysfunction. Surgery in rheumatoid nonambulatory (Ranawat Class IIIb) patients carries a significant risk. This study presents the surgical outcome of Class IIIb patients with CVJ rheumatoid myelopathy and reviews the literature. METHODS One hundred twelve consecutive patients with rheumatoid cervical myelopathy underwent surgical decompression and stabilization. Thirty-two of the patients (mean age, 66.81 +/- 10.25 yr) with CVJ rheumatoid arthritis were in Class IIIb, and all had atlantoaxial subluxation. A halo brace was applied before surgery and continued during surgery. Eleven patients with reducible atlantoaxial subluxation underwent direct posterior fusion. Twenty-one patients with fixed atlantoaxial subluxation underwent transoral decompression and then posterior fusion while they were under anesthesia. RESULTS At a mean follow-up of 39 months, four patients improved to Class II and 14 improved to Class IIIa, whereas six remained in Class IIIb. Neck pain was relieved in all patients. There was one perioperative death after transoral surgery (posterior fusion not done), and seven other patients died subsequently of causes unrelated to surgery. The morbidity of surgery included construct failure, cerebrospinal fluid leak, superficial wound or graft donor site infection, transient dysphagia, and lung infection. CONCLUSION A large subset of patients with CVJ rheumatoid myelopathy may reach Class IIIb. These patients have unique management considerations. Surgery (despite high morbidity) often remains the best therapeutic option available to them. Improvement of even one grade in their Ranawat score from Class IIIb to Class IIIa brought about by surgery confers on them a significant benefit in terms of their quality of life and survival.

Abstract
Rheumatic manifestation at the cervical spine occurs in more than 50% of all cases in the natural course of this disease. The first cervical manifestation takes place in the upper cervical spine. The initial involvement of the C1/C2 segment leads to atlantodental subluxation. Progressive destruction can result in vertical instability, which is characterized by cranial subluxation of the odontoid process with the danger of resulting stenosis and cervical myelopathy. The goal of diagnosis has to be the early recognition of these changes to establish an effective treatment protocol. Persistent pain, neurological deficits, and progressive radiological signs for instability are indications for operative stabilizing procedures. These procedures avoid progressive destruction and improve the prognosis regarding pain decrease, regression of neurological deficits, and life expectancy.

Abstract
Abstract
Background
Rheumatoid arthritis is a chronic inflammatory disease, which affects 1% of the population. Hands and feet are most commonly involved followed by the cervical spine. The spinal column consists of vertebrae stabilized by an intricate network of ligaments. Especially in the upper cervical spine, rheumatoid arthritis can cause degeneration of these ligaments, causing laxity, instability and subluxation of the vertebral bodies. Subsequent compression of the spinal cord and medulla oblongata can cause severe neurological deficits and even sudden death. Once neurological deficits occur, progression is inevitable although the rapidity of progression is highly variable. The first signs and symptoms are pain at the back of the head caused by compression of the major occipital nerve, followed by loss of strength of arms and legs. The severity of the subluxation can be observed with radiological investigations (MRI, CT) with a high sensitivity.
The authors have sent a Delphi Questionnaire about the current treatment strategies of craniocervical involvement by rheumatoid arthritis to an international forum of expert rheumatologists and surgeons. The timing of surgery in patients with radiographic instability without evidence of neurological deficit is an area of considerable controversy. If signs and symptoms of myelopathy are present there is little chance of recovery to normal levels after surgery.
Design
In this international multicenter randomized clinical trial, early surgical atlantoaxial fixation in patients with rheumatoid arthritis and radiological abnormalities without neurological deficits will be compared with prolonged conservative treatment. The main research question is whether early surgery can prevent radiological and neurological progression. A cost-effectivity analysis will be performed. 250 patients are needed to answer the research question.
Discussion
Early surgery could prevent serious neurological deficits, but may have peri-operative morbidity and loss of rotation of the head and neck. The objective of this study is to identify the best timing of surgery for patients at risk for the development of neurological signs and symptoms.

Abstract
The aim of this study was to determine the prevalence of C1/C2 involvement in rheumatoid arthritis (RA) in Czech patients and to identify typical pain symptoms and their relationship to radiologic findings at the C1/C2 level. Four hundred patients with RA were selected randomly and examined by plain X-ray. Cervical spine involvement was found in 45.8% of these patients. Cervicocranial syndrome was the most common symptom of any spine involvement at the C1/C2 level and was present in 54.6%. Cervicocranial syndrome was typical for ventral subluxation 3-6 mm and was found in 52.9%. The distance of 8 mm or more was associated with mild pain. The pain intensity at the C1/C2 level decreased with increasing distance of ventral atlantoaxial subluxation (P < 0.0001).

EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2004; 13:266-73.

Abstract
The author presents a retrospective clinical study addressing the outcome after posterior stabilisation of the occipital-cervical spine using a new cranio-spinal implant. The range of surgical methods for operative treatment of occipito-cervical instability remains wide, and it is still a demanding technique that frequently requires improvisation by the surgeon. No previous studies have been published of occipito-cervical reconstructions using two contoured asymmetrical occipital plates interdigitating in the midline at the occiput and allowing various methods of cervical fixation, by means of different hooks, a claw device or screws. Nine patients with severe occipito-cervical instability and/or subaxial malalignment underwent reconstructive surgery with the new implants between 1998 and 2001. Seven patients suffered from rheumatoid arthritis (RA) including cranial settling. Two patients had widespread cervical metastases. All patients suffering RA were treated by preoperative cervical traction for up to 28 days, and intraoperative traction, to try to restore the malalignment. Traction was also used, to diminish pain and to improve neurological symptoms. The lowest vertebra fused was T3. All patients were immobilised with an external orthosis or brace for 6 weeks or 3 months. A solid fusion was achieved in all patients. None of the patients deteriorated postoperatively. No serious complications occurred. One occipital screw broke and one hook loosened, needing a re-fixation. The simplicity of applying these cranio-cervical implants makes them practical for every orthopaedic or neurosurgeon with a special interest in cervical spine surgery.
