We retrospectively examined the outcomes of occipitocervicothoracic fixation using a hook and rod system for rheumatoid patients
with cervical myelopathy in which decompression of the spinal cord and spinal fusion were performed simultaneously at multiple
levels. There were 10 female patients with rheumatoid arthritis (ages 51–77 years, average 62.8 years; follow-up period 6
months to 3 years and 9 months, average 2 years and 8 months). Atlantoaxial subluxation was found in 5 patients, vertical
subluxation in 4 patients, and subaxial subluxation in 8 patients. The progression of the disorder was assessed as class 4
stage 4 in 3 patients and class 3 stage 4 in 7 patients. The average time taken for surgery was 4 h 41 min, and the average
volume of blood loss was 729 ml. There were no complications during surgery. One patient died of malignant lymphoma 1 month
after surgery, and one patient died of heart failure 2 years and 3 months after surgery. The average Japanese Orthopaedic
Association (JOA) score improved from 7.0 preoperatively to 9.5 postoperatively. Preoperative nuchal pain in 3 patients and
difficulty in breathing on flexion of the cervical spine in 2 patients were improved after surgery. Good bony union was obtained
in 9 patients. The exception being one patient who died of a disease unrelated to the surgery 1 month postoperatively. Occipitocervicothoracic
fixation using a hook and rod system is an easy and safe procedure, and can facilitate not only good bony union, but also
adequate decompression of the spinal cord with simultaneous laminoplasty because of the secure long fixation extending to
the upper thoracic level and bilateral grafting of a considerable volume of bone. 相似文献

The paper analyzes the outcomes of surgical treatment in 19 patients with tuberculosis of the cervical part of the vertebral column. All the patients had surgical treatment: abscessotomy, sparing resection of a destruction area, decompression of the spinal cord, removal of kyphotic deformity by restoring the axis of the vertebral column. The existing defect was filled with an autograft in 7 cases, with a biocompatible implant by applying benemycin to its surface in 12 cases. Posterior fixation of the diseases part of the spinal apparatus was made in 8 cases. Good outcomes were followed up 8 months to 7 years after surgery. At X-ray study, the bony block formed between the resected vertebral bodies within 3 to 7 months. Neurological symptoms were arrested in all cases, except 4 ones. One patient was found to have a slight lower extremity weakness and 3 patients had correctable radicular symptoms. 相似文献

Cutaneous sensory impairment in rheumatoid atlanto-axial subluxation assessed quantitatively by electrical stimulation 总被引:1,自引:0,他引:1
G Toolanen 《Scandinavian journal of rheumatology》1987,16(1):27-32
Thresholds for cutaneous perception and pain in 27 rheumatoid patients were investigated by electrical stimulation. Patients with atlanto-axial subluxation showed impaired sensibility over the ophthalmic division of the trigeminal nerve. Patients with vertical atlanto-axial subluxation showed in addition to a pronounced decrease in the sensibility over the ophthalmic and maxillary divisions of the trigeminal nerve, also sensory disturbances over cervical, thoracic and lumbar levels. The mandibular division was never affected. The trigeminal sensibility seems to be affected early in the rheumatoid atlanto-axial subluxation and progresses with the severity of the subluxation, possibly due to bony compression of the trigeminal spinal tract at C 1 level. 相似文献

Cervical spine involvement in rheumatoid arthritis (RA) is considered a feature of long-standing disease. We describe two patients who presented with cervical symptoms as early features of RA.Methods
We report two RA cases with cervical spine involvement as early features and use MEDLINE to review the literature concerning the frequency and disease duration of this manifestation and its imaging with plain radiography, computed tomography (CT), and magnetic resonance imaging (MRI).Results
An 80-year-old man with cervical myelopathy from a C1–C2 rheumatoid pannus underwent decompression surgery before development of peripheral synovitis from RA. A 63-year-old woman presented with neck pain and polyarthritis at RA diagnosis, with imaging that confirmed a C1–C2 rheumatoid pannus. Onset of cervical spine involvement in RA is generally after 10 years of disease duration, ranging from 3 months to 45 years after peripheral synovitis among patients with seropositive erosive RA. Occurring in 9–88% of RA patients, cervical spine involvement may result in cervical instability due to either mechanical compression or vascular impairment of the spinal cord. Bone erosions and atlanto-axial subluxation on standard radiographs are two major signs of cervical spine involvement in RA. MRI identifies earlier signs of RA and has a higher sensitivity in detecting bone erosions compared to conventional radiography.Conclusions
Cervical spine involvement in RA is not an uncommon condition but is rare at early disease onset. Symptoms of cervical pain and myelopathy should prompt a thorough neurological examination accompanied by imaging. 相似文献10.

Physical factors such as frequency of low back pain, sensory abnormalities in the lower extremities, smoking history before surgery, and preoperative mental health status as predictors of operative outcomes have been growing as areas of interest in the field of degenerative lumbar spinal stenosis (DLSS). This study aimed to investigate the correlation between the preoperative Short Form-36 Mental Component Score (SF-36 MCS) and long-term prognosis after decompression surgery for DLSS. In total, 198 patients were enrolled in this study. The Oswestry Disability Index (ODI) and Rolland Morris Disability Questionnaire (RMDQ) were used to evaluate spinal functional outcomes. The SF-36 questionnaire was used and analyzed by classifying it into physical component score (PCS) and mental component score (MCS). The SF-36 MCS was divided into role limitations caused by emotional problems, social functioning, vitality, and emotional well-being. In the correlation between preoperative MCS and ODI improvement, the r value was −0.595 (P < .05) at 12 months postoperatively. ODI improvement at 12 months after decompression surgery showed a statistically significant and strong negative correlation with preoperative MCS. In the correlation between preoperative MCS and RMDQ improvement, the r value was −0.544 (P < .05) at 12 months postoperatively. Therefore, RMDQ improvement 12 months after decompression surgery showed a strong negative correlation with preoperative MCS. Regarding the correlation between preoperative MCS and SF-36 PCS improvement, the r values were 0.321 (P < .05) at 6 months postoperatively and 0.343 (P < .05) at 12 months postoperatively. Therefore, SF-36 PCS improvement at 6 and 12 months after decompression surgery showed a strong positive correlation with preoperative SF-36 MCS scores. Preoperative SF-36 MCS is a factor that can predict the prognosis of patients who underwent decompression surgery for lumbar spinal stenosis for at least 1 year postoperatively. 相似文献

Cervical myelopathy is a rare but potentially dangerous complication of rheumatoid arthritis and presents considerable therapeutic problems. A conservative approach carries high mortality and surgical intervention is not without serious risks. Reduction of subluxation and posterior fusion is widely practised but may require prolonged bed rest and continuous skull traction, sometimes for many weeks. When anterior decompression has been attempted prolonged immobilisation and external fixation have created problems. In this series 23 rheumatoid patients with cervical myelopathy were investigated over a four-year period. Seventeen underwent anterior decompression of the cervical cord, of whom 14 had a transoral removal of the odontoid peg and pannus and posterior occipitocervical fusion during the same anaesthetic without mortality or serious postoperative complications; all but one have improved. The authors believe that early mobilisation after a combined cord decompression and internal fixation has reduced the mortality and morbidity. Management of cervical myelopathy in rheumatoid arthritis and indications for operation are discussed. 相似文献

OBJECTIVE: To study the prevalence of cervical spine subluxation in patients with rheumatoid arthritis waiting for orthopaedic surgery, and symptoms that might be associated with the disorders. METHODS: 194 patients with rheumatoid arthritis were referred for orthopaedic surgery at Jyv?skyl? Central Hospital, 154 (79%) of whom volunteered for the present study including clinical examination, laboratory tests, radiographs of the cervical spine, hands, and feet, and self report questionnaires. Definition of anterior atlantoaxial subluxation (aAAS) was >3 mm and of subaxial subluxation (SAS)>or=3 mm. Atlantoaxial impaction (AAI) was analysed following to the Sakaguchi-Kauppi method. RESULTS: 67 patients (44%) had cervical spine subluxation or previous surgical fusion. The prevalence of aAAS, AAI, SAS, or previous fusion was 27 (18%), 24 (16%), 29 (19%), and 8 (5%), respectively; 69% of patients with cervical spine subluxations (those with fusions excluded) reported neck pain, compared with 65% of patients without subluxations (p=0.71). The prevalence of occipital, temporal, retro-orbital, and radicular pain in upper extremities was similar in patients with or without cervical spine subluxations (54% v 43%; 17% v 31%; 25% v 24%; 47% v 48%, respectively). However, patients with subluxations were older, had longer disease duration, more active disease, poorer function according to the Health Assessment Questionnaire, and had more often erosive disease. CONCLUSIONS: Asymptomatic cervical spine subluxation is common in patients with rheumatoid arthritis waiting for orthopaedic surgery. Regardless of symptoms, the possibility of cervical spine subluxation in patients with severe rheumatoid arthritis should be considered in preoperative evaluation. 相似文献

Clinical characteristics affecting survival in patients with rheumatoid arthritis undergoing cervical spine surgery: a controlled study 总被引:1,自引:0,他引:1
A controlled study of the clinical characteristics affecting survival in patients with rheumatoid arthritis (RA) with cervical spine involvement treated surgically demonstrated a strong association between disease severity, the frequency of severe extraarticular manifestations, especially interstitial lung disease, and a decreased probability of survival. These probabilities at 1 and 5 years postoperatively were 74 and 54%, respectively. Death resulted most often from infection or comorbid conditions. All surgery patients with interstitial lung disease died within 28 months postoperatively. In patients with RA undergoing cervical spine surgery, fatality rates appear to be increased in patients with severe extraarticular manifestations, especially interstitial lung disease. 相似文献

This retrospective cohort study was conducted to evaluate the clinical outcomes of radical anterolateral debridement and autogenous ilium with rib or titanium cage interbody autografting with transpedicle fixation for the treatment of thoracolumbar tuberculosis.Spinal tuberculosis operation aims to remove the lesions and necrotic tissues, remove spinal cord compression, and reconstruct spinal stability. However, traditional operation methods cannot effectively correct cyrtosis or stabilize the spine. In addition, the patient needs to stay in bed for a long time and may have many complications. So far, the best surgical method and fixation method for spinal tuberculosis remain controversial.There were a total of 43 patients, 16 involving spinal cord injury, from January 2004 to January 2011. The patients were surgically treated for radical anterolateral debridement via posterolateral incision and autogenous ilium with rib or titanium cage interbody autografting and single-stage transpedicle fixation. All the patients were followed up to determine the stages of intervertebral bone fusion and the corrections of spinal kyphosis with the restoration of neurological deficit.The erythrocyte sedimentation rate (ESR) of these patients decreased to normal levels for a mean of 2.8 months. The function of feeling, motion, and sphincter in 16 paraplegia cases gradually recovered after 1 week to 3 months postoperatively, and the American Spinal Injury Association scores significantly increased at the final follow-up. Intervertebral bone fusions were all achieved postoperatively. No internal fixation devices were loose, extracted, or broken. There was no correction degree loss during the follow-up.The method of radical anterolateral debridement and autogenous ilium with rib or titanium cage interbody autografting and single-stage transpedicle fixation was effective for the treatment of thoracolumbar tuberculosis, correcting kyphotic deformity, and reconstructing spinal stability, obtaining successful intervertebral bony fusion and promoting the recovery of paraplegia. These results showed satisfactory clinical outcomes. 相似文献

The cervical spine radiographs of 100 patients with early rheumatoid disease were studied annually, on a prospective basis, for a mean follow-up period of 7 years 2 months. Atlantoaxial subluxation developed in 12 patients. The subluxation was more frequent in females, more severe in patients with progressive, seropositive, erosive rheumatoid disease, and more marked in patients treated with oral corticosteroids. Subaxial subluxation, affecting upper cervical disc levels, occurred in a further 20 patients. Three patients developed vertical subluxation. The mobility of the cervical spine affects the degree of subluxation achieved, and when assessing serial films for subluxation it may be necessary to measure the cervical spine flexion before deciding whether subluxation has progressed or not. Over 80% of the patients with subluxation developed the first evidence of subluxation within 2 years of disease onset. Subluxation in the cervical spine is not, therefore, a late complication of rheumatoid disease. During the follow-up period none of the patients developed neurological signs. 相似文献

Rheumatoid arthritis patients who had secondary amyloidosis have been studied retrospectively. There were eight patients out of 105 rheumatoid arthritis patients who had total joint replacement surgery from 1979 to 1990 in our institute. The grade of inflammation, renal and hepatic function have been compared with the RA patients without amyloidosis pre- and post- operatively. All of eight patients was female, and their average age at the diagnosis of amyloidosis was 57.8 year-old (range 4-76 year-old). The average preoperative period was 14.4 years (range 4-27 years), and the secondary amyloidosis had been diagnosed at the time of 3.8 years (range 1-9 years) after operation. The major clinical features leading to the diagnosis were gastrointestinal disturbance in six cases and renal dysfunction in two cases. The data of the renal function of amyloidosis patients showed slightly lower than that of the RA patients without amyloidosis, and showed significantly decrease postoperatively. The white blood cell (WBC) count was higher at the time of operation in the amyloidosis patients and showed continuous increase postoperatively. Lansbury index, alpha 2-globulin and WBC count did not improve in the amyloidosis patients during three years after operation. On the contrary, the patients without amyloidosis improved in these clinical data during the same period. Three amyloidosis patients died of renal failure and one died of bronchopneumonia. The average survival period was 1.8 years (range 1-5 years) after diagnosis of amyloidosis, and was 6.3 years (range 2-10 years) after operation in these four patients.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献
