OBJECTIVE--To assess whether a simple strategy would sustain a reduction in the number of unnecessary x ray examinations. DESIGN--Use of posters to display guidelines encouraging the more effective use of radiology in patients with head injuries, twisted ankles, neck injuries, and abdominal pain. SETTING--Accident department of a large metropolitan district general hospital. PATIENTS--15,875 patients attending the accident department over two years. MAIN OUTCOME MEASURE--Proportion of patients having radiography. RESULTS--Referrals for skull radiography fell from 56% to 20% and those for abdominal radiography fell from 31% to 7%. Referral patterns for adults attending with twisted ankles and cervical spine injuries did not change. Reductions were sustained over two years. CONCLUSION--Carefully designed posters provide a simple method of reducing unnecessary x ray examinations. 相似文献

Increasing workloads in our radiology department prompted a study of casualty officers'' use of x ray examinations, of which there were 5463 in the period. While casualty officers were in post referrals for x ray examination did not become more selective, but skills in interpreting films improved. Overall, 4.9% of trauma radiographs were misinterpreted, but this fell from 7.1% to 2.9% during tenure of post. One in four errors was clinically important. Clinical guidelines for selective radiography produced a significant and sustained reduction in the number of x ray examinations requested by the department. Analysis of one common injury indicated that the quality of patient care was not adversely affected. The number of x ray examinations carried out in the accident and emergency department can be reduced by using guidelines, and this does not compromise the quality of patient care. Appreciable savings may be made in patients'' waiting times and radiodiagnostic expenditure. 相似文献

Forty-one patients with rheumatoid arthritis involving the cervical spine had a posterior cervical arthrodesis. They were followed for a minimum period of seven years. The diagnoses prior to surgery included cranial settling, atlantoaxial subluxation, subaxial subluxation, and any combination of these three. All patients had posterior arthrodesis, with or without methylmethacrylate, and iliac crest autogenous bone graft. In addition, one patient had an anterior vertebrectomy, and two had transoral resection of the odontoid. Follow-up consisted of a subjective questionnaire, standard radiographs, and physical examination, including a neurologic exam. This information was compared to preoperative data available in the patient''s medical record, postoperative data, and the information obtained in a similar study undertaken in 1987. At the time of follow-up, thirteen patients were known to be dead. One patient could not be located. Of the remaining twenty-six patients, eighteen underwent the full examination, including physical exam and radiographs. The remaining nine patients were contacted and interviewed, but were unavailable for exam and radiographs. All patients considered the operation a success. Only one patient at follow-up had a non-union. This was stable over time. No patient had a deterioration in neurologic function. There was no significant degeneration or instability seen at levels adjacent to the fused segments as compared to the rest of the cervical spine. Posterior cervical spine arthrodesis for rheumatoid involvement of the neck is a safe, efficacious procedure with no significant deterioration of effects over time. 相似文献

OBJECTIVE--To assess premenopausal women with inflammatory changes on cervical cytology for genital infections and cervical abnormalities. DESIGN--Prospective study of women attending general practice and family planning clinics who had a recent cervical cytology result with inflammatory changes. SETTING--Department of genitourinary medicine. PATIENTS--102 Premenopausal women with recent cytology result showing inflammatory changes and with no history of antibiotic or antifungal treatment since their smear. INVESTIGATIONS--Genital examination and microbiological screening for genital infections; colposcopic examination about six weeks later. MAIN OUTCOME MEASURES--Detection of genital infections, particularly those sexually acquired, and abnormalities on colposcopy. RESULTS--Genital infections were isolated in 77 patients, and one or more sexually acquired infections were found in 22. Prevalence of sexually acquired infections was significantly correlated with younger age (particularly being under 25), being single, separated, or divorced; using non-barrier contraception; and recent change of sexual partner. An abnormality on colposcopy was found in 36 women. There was a strong correlation of a sexually acquired infection with an abnormality at colposcopy; hence younger women were more likely to have a colposcopic abnormality. CONCLUSIONS--Inflammatory changes on cytology are often associated with the presence of a sexually acquired infection and premalignant disease of the cervix, particularly in younger, single women using non-barrier contraception. 相似文献

Background Context
There are few comparisons of Modic changes (MCs) in the lumbar and cervical spine.Purpose
Compare the prevalence of MCs in the lumbar and cervical spine, and determine how MC prevalence depends on spinal pain, age, disc degeneration, spinal level, and the presence or absence of kyphosis.Study Design
Retrospective clinical survey.Materials and Methods
Magnetic resonance images (MRIs) were compared from five patient groups: 1. 1223 patients with low-back pain/radiculopathy only; 2. 1023 patients with neck pain/radiculopathy only; 3. 497 patients with concurrent low-back and neck symptoms; 4. 304 asymptomatic subjects with lumbar MRIs; and 5. 120 asymptomatic subjects with cervical MRIs.Results
The prevalence of MCs was higher in those with spinal pain than in those without, both in the lumbar spine (21.0% vs 10.5%) and cervical spine (8.8% vs 3.3%). Type II MCs were most common and Type III were least common in all groups. The prevalence of lumbar MCs in people with back pain was little affected by the presence of concurrent neck pain, and the same was true for the prevalence of cervical MCs in people with neck pain with or without concurrent back pain. When symptomatic patients were reclassified into two groups (back pain, neck pain), the prevalence of lumbar MCs in people with back pain was greater than that of cervical MCs in people with neck pain. The prevalence of lumbar and cervical MCs increased with age, disc degeneration, (descending) spinal level, and increased kyphosis.Conclusions
There is a significantly higher prevalence of MCs in patients with back and neck pain. The reported association with increased kyphosis (flat back) is novel. 相似文献9.

OBJECTIVE: To, assess the emergency department use of cervical spine radiography for alert, stable adult trauma patients in terms of utilization, yield for injury and variation in practices among hospitals and physicians. DESIGN: Retrospective survey of health records. SETTING: Emergency departments of 6 teaching and 2 community hospitals in Ontario and British Columbia. PATIENTS: Consecutive alert, stable adult trauma patients seen with potential cervical spine injury between July 1, 1994, and June 30, 1995. MAIN OUTCOME MEASURES: Total number of eligible patients, referral for cervical spine radiography (overall, by hospital and by physician), presence of cervical spine injury, patient characteristics and hospitals associated with use of radiography. RESULTS: Of 6855 eligible patients, cervical spine radiography was ordered for 3979 (58.0%). Only 60 (0.9%) patients were found to have an acute cervical spine injury (fracture, dislocation or ligamentous instability); 98.5% of the radiographic films were negative for any significant abnormality. The demographic and clinical characteristics of the patients were similar across the 8 hospitals, and no cervical spine injuries were missed. Significant variation was found among the 8 hospitals in the rate of ordering radiography (p < 0.0001), from a low of 37.0% to a high of 72.5%. After possible differences in case severity and patient characteristics at each hospital were controlled for, logistic regression analysis revealed that 6 of the hospitals were significantly associated with the use of radiography. At 7 hospitals, there was significant variation in the rate of ordering radiography among the attending emergency physicians (p < 0.05), from a low of 15.6% to a high of 91.5%. CONCLUSIONS: Despite considerable variation among institutions and individual physicians in the ordering of cervical spine radiography for alert, stable trauma patients with similar characteristics, no cervical spine injuries were missed. The number of radiographic films showing signs of abnormality was extremely low at all hospitals. The findings suggest that cervical spine radiography could be used more efficiently, possibly with the help of a clinical decision rule. 相似文献

Clinical theory suggests that altered alignment of the shoulder girdle has the potential to create or sustain symptomatic mechanical dysfunction in the cervical and thoracic spine. The alignment of the shoulder girdle is described by two clavicle rotations, i.e, elevation and retraction, and by three scapular rotations, i.e., upward rotation, internal rotation, and anterior tilt. Elevation and retraction have until now been assessed only in patients with neck pain. The aim of the study was to determine whether there is a pattern of altered alignment of the shoulder girdle and the cervical and thoracic spine in patients with neck pain. A three-dimensional device measured clavicle and scapular orientation, and cervical and thoracic alignment in patients with insidious onset neck pain (IONP) and whiplash-associated disorder (WAD). An asymptomatic control group was selected for baseline measurements. The symptomatic groups revealed a significantly reduced clavicle retraction and scapular upward rotation as well as decreased cranial angle. A difference was found between the symptomatic groups on the left side, whereas the WAD group revealed an increased scapular anterior tilt and the IONP group a decreased clavicle elevation. These changes may be an important mechanism for maintenance and recurrence or exacerbation of symptoms in patients with neck pain. 相似文献

OBJECTIVE--To determine whether length of hip axis in elderly women has increased over the past 40 years and, if so, whether the increase may have contributed to the increase in the age adjusted rate of hip fractures during those years. DESIGN--Retrospective assessment of anteroposterior x ray films of the pelvis. SETTING--Radiology department of a rheumatology hospital, New Zealand. PATIENTS--Two cohorts of women aged > 60 (mean 70) who were x rayed on the same apparatus in either the 1950s or the 1990s. MAIN OUTCOME--Length of hip axis (distance from the medial aspect of the pelvis to the lateral aspect of the femur along the axis of the femoral neck), length of femoral neck (length of hip axis excluding the femoral head and more medial structures), and width of femoral neck (see figure). RESULTS--Both the mean length of the hip axis and the mean length of the femoral neck were significantly greater in the women whose x ray films were taken in the 1990s than in those in the 1950s (124.0 mm (SE 1) v 130.5 (1), P = 0.0002; 79.4 (1) v 84.9 (1), P < 0.0001, respectively). The width of the femoral neck did not change, and the lengths expressed as ratios to width were greater in the more recent x ray films, indicating that these findings are not due to an unrecognised change in radiographic technique. CONCLUSIONS--An increase in the length of the hip axis in elderly women in New Zealand during the past 40 years has occurred which is large enough to account for the increase in the age adjusted rate of hip fractures during those years. 相似文献

Nine patients with serious cervical spine injuries that occurred while they were playing rugby were seen in a British Columbia acute spinal cord injury unit during the period 1975-82. All the injuries had occurred during the "scrum" or the "tackle". Two of the patients were rendered permanently quadriplegic, and one patient died. There is a need for a central registry that would record all cervical spine injuries in rugby players as well as for changes in the rules of the game. 相似文献

Occupations that involve sustained or repetitive neck flexion are associated with a higher incidence of neck pain. Little in vivo information is available on the impact of static neck flexion on cervical spinal tissue. The aim of this study was to assess changes in mechanical and neuromuscular behaviors to sustained neck flexion in healthy adults. Sixty healthy subjects aged 20–35 years participated in this study. The participants were exposed to static neck flexion at a fixed angle of full flexion for 10 min. Mechanical and neuromuscular responses of the cervical spine to sudden perturbations were measured pre- and post-exposure. Magnitude of load-relaxation during flexion exposure, stiffness, peak head angular velocity, and reflexive activities of cervical muscles were recorded. Effective neck stiffness decreased significantly, especially in female participants (P = 0.0001). The reflexive response of the cervical erector spinae muscles to head perturbation delayed significantly (P = 0.0001). Peak head angular velocity was significantly increased after exposure to neck flexion for 10 min, especially in female participants (P = 0.001). In the present study, static flexion resulted in changes in mechanical and neuromuscular behavior of the cervical spine, potentially leading to decreased stiffness of the cervical spine. The results confirm the importance of maintaining a correct head and neck position during work and improving the work environment to reduce the cervical spinal load and work-related neck pain. 相似文献

Objective
To estimate the effectiveness of anterior cervical discectomy with arthroplasty (ACDA) compared to anterior cervical discectomy with fusion (ACDF) for patient-important outcomes for single-level cervical spondylosis.Data sources
Electronic databases (MEDLINE, EMBASE, Cochrane Register for Randomized Controlled Trials, BIOSIS and LILACS), archives of spine meetings and bibliographies of relevant articles.Study selection
We included RCTs of ACDF versus ACDA in adult patients with single-level cervical spondylosis reporting at least one of the following outcomes: functionality, neurological success, neck pain, arm pain, quality of life, surgery for adjacent level degeneration (ALD), reoperation and dysphonia/dysphagia. We used no language restrictions. We performed title and abstract screening and full text screening independently and in duplicate.Data synthesis
We used random-effects model to pool data using mean difference (MD) for continuous outcomes and relative risk (RR) for dichotomous outcomes. We used GRADE to evaluate the quality of evidence for each outcome.Results
Of 2804 citations, 9 articles reporting on 9 trials (1778 participants) were eligible. ACDA is associated with a clinically significant lower incidence of neurologic failure (RR = 0.53, 95% CI = 0.37–0.75, p = 0.0004) and improvement in the Neck pain visual analogue scale (VAS) (MD = 6.56, 95% CI = 3.22–9.90, p = 0.0001; Minimal clinically important difference (MCID) = 2.5. ACDA is associated with a statistically but not clinically significant improvement in Arm pain VAS and SF-36 physical component summary. ACDA is associated with non-statistically significant higher improvement in the Neck Disability Index Score and lower incidence of ALD requiring surgery, reoperation, and dysphagia/dysphonia.Conclusions
There is no strong evidence to support the routine use of ACDA over ACDF in single-level cervical spondylosis. Current trials lack long-term data required to assess safety as well as surgery for ALD. We suggest that ACDA in patients with single level cervical spondylosis is an option although its benefits and indication over ACDF remain in question. 相似文献16.
The kinematic function of the cervical spine has been examined previously by means of cineradiography or a sequence of lateral X-rays, usually of a flexion-extension range of motion. Interpretation of these studies, however, presents difficulties. One of the major problems is how to extract information from the X-ray images which is not only explicit, quantitative and accurate, but which is also diagnostically useful. Another problem is that as one increases the number of steps of motion between full flexion and full extension to obtain a more detailed examination, one also increases the amount of radiation exposure and the bulk of the data.
Reported here is a technique which uses one lateral-view X-ray for each of five neck positions: full flexion, full extension, and three intermediate positions. From each set of X-rays, various parameters are derived to describe two types of data: kinematic (angles and centers of rotation), and geometric (pattern of curvature). This technique has been shown capable of identifying functional abnormalities in patients with neck pain who have no structural abnormalities detectable by X-ray. Further experience will be useful in better defining various types of functional abnormalities. 相似文献

The cervical smear and biopsy results were reviewed for 141 patients who were referred for colposcopy with either a technically unsuitable smear or with cervical smear abnormalities less severe than dyskaryosis. The number of referrals due to minor smear abnormalities more than doubled from 8.6% to 22.3% of the total colposcopy referrals over the 4 year period studied. The minor smear abnormalities were only associated with cervical intraepithelial neoplasia (CIN) in patients aged <50 years. In 19 (13.5%) of the 141 patients high-grade lesions (CIN II or CIN III) were diagnosed. There were no cases of invasive cancer. Furthermore, the increased number of patients being referred for colposcopy with minor cervical smear abnormalities highlights the increasing pressures on colposcopy services, with prolonged waiting times for all patients. 相似文献

This report describes a patient who had an open repair of a small supraspinatus tendon tear performed 6 months after an arthroscopic acromioplasty with debridement had failed to provide pain relief. Three months prior to the tendon repair, he had a two-level cervical spine discectomy and fusion (C4–5, C5–6) that improved his neck pain. Florid suprascapular neuropathy was detected 10 weeks after the open rotator cuff repair. Evidence of some nerve recovery resulted in a long period of observation. But unsatisfactory improvement warranted decompression of the suprascapular notch, which was found to be very stenotic. At surgery, there was no evidence of neuroma, cyst, or other compressing lesion or tissue. Therefore, it was ultimately hypothesized that there was an exacerbation of a preexisting, but clinically unrecognized, entrapment of the suprascapular nerve in the suprascapular notch in the setting of cervical radiculopathy (primarily C5). Retrospectively it was also concluded that had this compressive etiology been recognized, it would have favored prompt decompression rather than the long observation period. Three years was required to achieve a good result following suprascapular notch decompression. The underlying C5 radiculopathy may have created a “double crush syndrome” that contributed to the propensity for injury and the prolonged recovery. There should be heightened awareness of this problem in patients who do not have satisfactory improvement in shoulder pain from previous shoulder and neck surgery. 相似文献

Knowledge on the spinal kinematics and muscle activation of the cervical and thoracic spine during functional task would add to our understanding of the performance and interplay of these spinal regions during dynamic condition. The purpose of this study was to examine the influence of chronic neck pain on the three-dimensional kinematics and muscle recruitment pattern of the cervical and thoracic spine during an overhead reaching task involving a light weight transfer by the upper limb. Synchronized measurements of the three-dimensional spinal kinematics and electromyographic activities of cervical and thoracic spine were acquired in thirty individuals with chronic neck pain and thirty age- and gender-matched asymptomatic controls. Neck pain group showed a significantly decreased cervical velocity and acceleration while performing the task. They also displayed with a predominantly prolonged coactivation of cervical and thoracic muscles throughout the task cycle. The current findings highlighted the importance to examine differential kinematic variables of the spine which are associated with changes in the muscle recruitment in people with chronic neck pain. The results also provide an insight to the appropriate clinical intervention to promote the recovery of the functional disability commonly reported in patients with neck pain disorders. 相似文献
