人工关节松动病因的研究   总被引:28,自引:0,他引:28  
范卫民  王青 《中华骨科杂志》1998,18(9):518-521,I001
目的:探讨人工关节松动的病因。方法:选择7例松动人工髋关节,翻修手术时取松动关节周围的界膜组织;同时选择10例骨折内固定患者,拆除内固定物时取内固定物周围瘢痕组织。标本做组织学检查和肿瘤坏死因子(TNF)测定。选择10只成年兔,将20只模拟假体分别置入双侧股骨远端。分别于术后第6、8、10、12、14周向右侧膝关节腔注射聚乙烯微粒悬液,作为实验侧;左侧膝关节腔注射生理盐水,作为对照侧。第16周取股骨远端标本,做组织学检查。结果:松动人工髋关节周围的界膜组织主要含大量的组织细胞和聚乙烯微粒,而骨折内固定物周围的瘢痕组织主要为纤维成分,无聚乙烯微粒。松动关节周围界膜组织中的TNF浓度明显高于骨折内固定物周围的瘢痕组织(P<0.01)。动物实验发现,实验侧模拟假体周围有一层充满组织细胞的纤维结缔组织界膜,并有明显骨吸收和骨溶解现象,而对照侧无明显纤维结缔组织界膜,也无骨破坏现象。结论:人工关节磨损后,产生大量的磨损微粒,微粒刺激组织细胞分泌TNF等溶骨性因子,这些溶骨性因子直接或间接地激活破骨细胞,从而引起假体周围骨吸收、骨溶解,最终导致假体松动。假体松动后又可加重磨损,产生更多的微粒,形成恶性循环  相似文献

Summary A survey of all members of the Swiss Medical Association of Manual Medicine was undertaken for the year 1989. Informative data were given by 425 respondents on the frequency of complications of manipulation as related to the spine. The number of thoraco-lumbar manipulations during 1989 (225 working days) was 805 for each respondent, and the number manipulations of the cervical spine 354. Thus, the total number of thoraco-lumbar manipulations was 342 125, and the total number of cervical manipulations was 150 450. The overall incidence of side-effects of transient complications due to cervical spine manipulation such as disturbance of consciousness or radicular signs was 1: 16716. Seventeen patients (ratio 1: 20 125) after manipulation of the lumbar spine presented, in addition to increased pain, a transient sensorimotor deficit with precise radicular distribution. Nine of the 17 patients (ratio 1: 38013) developed a progressive radicular syndrome with sensorimotor defict and radiologically verified disc herniation and had to be referred for surgery. Side effects and complications of cervical and lumbar spine manipulation are rare. Taking in to account the yearly number of manipulations performed by a single physician in Switzerland and the rate of complications, it can be calculated that a physician practicing manual medicine will encoutner one complication due to manipulation of the cervical spine in 47 years and one complication due to lumbar spine manipulation in 38 years of practice. However, it is important that a careful clinical assessment is carried out to avoid complications due to manipulation carried out on the basis of inappropriate indications. Furthermore, the decision as to which technique is indicated for any particular functional disorder of the spine should be made on the basis of rational criteria resting on a knowledge of clinical biomechanics, functional anatomy and neurophysiology. The authors recommend a prospective morbidity study to be carried out among physicians, chiropractors, osteopaths and physiotherapists, taking into account the different indications and therapeutic techniques in relation to complications.  相似文献

STUDY DESIGN: Prospective comparative study. OBJECTIVE: To compare the efficacy of the ASIA scoring system and Tuli's classification for assessment of neurological status in a typical case of Pott's paraplegia/tetraplegia and suggest a suitable classification. SETTING: Department of Orthopaedics of University College of Medical Sciences and GTB Hospital, Delhi, India. METHODS: A total of 33 cases of tuberculosis of the spine with paraplegia were evaluated serially for the severity of the neurological deficit by grading systems as suggested by Tuli and ASIA score, during the course of treatment. A total of 111 readings of neurological status were recorded and analysed. RESULTS: Tuli's grading was found to be sensitive for detection of early stage (grade I) of neurological deficit. The rest of the grades (grade II, III, IV) of Tuli's classification have a wide range of sensory-motor deficit and hence are insensitive to early detection of any deterioration/improvement in the neurological status. The ASIA score failed to grade all types of neurological deficit associated with the Pott's spine. The sensory-motor score obtained by the ASIA scale depends on the level of involvement of the spinal cord. The higher the level of the cord damage, the poorer is the score. CONCLUSION: Neither Tuli's grading nor the ASIA scale alone can effectively grade all stages of neurological deficit in tuberculosis of the spine. The neurological deficit in tuberculosis of the spine should be described in stages and each stage should have sensory and motor scoring. A new staging system of Pott's tetraplegia/paraplegia is suggested.  相似文献

The study was undertaken to determine whether existing systems of outcome evaluation of clubfoot are comparable; to determine the relationship between the shape of the foot, its function, and radiological tarsal relationships; and to identify which objective variables used in the assessment of clubfeet are reproducible.Fifty treated idiopathic clubfeet were assessed by the scoring systems of Laaveg and Ponseti, McKay, Magone, and Ghanem and Seringe. Although there was a good correlation between the scores, there was very poor agreement between the grading of feet by these different systems.The feet were also evaluated using a new scoring system that has 3 domains of evaluation, viz, morphological, functional, and radiological. Comparison of the scores in each of these domains showed that there was a correlation between morphology, function, and radiological measurements of tarsal alignment. Several of the criteria used in this new scoring system were reproducible.  相似文献

Total endoprosthesis of the hip joint is an effective method of rehabilitation of patients with a severe pathology of the hip joint. But the lack of exact criteria of assessment of restriction of vital activity of patients after total endoprosthesis results in leveling the effects of medical rehabilitation due to the existing stereotype solution of the MSE bureau and so the majority of patients (90%) after operation get invalidization of the I and II groups for a long time without sufficient causes. Results of complex clinico-rentgenological, biomechanical, electrophysiological examinations and expert assessment of 450 patients after implantation of various domestic and foreign endoprostheses allowed the elaboration of differentiated criteria for the examination of restricted viral activity depending on the nosological form of the disease, degree of the disturbance of the statico-dynamic function, prognosis, complications, character and conditions of work.  相似文献

The authors present their experience in the treatment of 74 patients with unilateral fractures of the femur and the bones of the crus. The peculiarities of these injuries which unfavourably affect the results of the treatment are discussed. Four versions of treatment are distinguished, with surgical treatment of fractures of the femur and the bones of the crus being the preferable one. The best results, concerning both the duration of the period of in-patient treatment and the final outcome, were obtained in cases of combined intraosseous osteosynthesis of the femur and perosseous osteosynthesis of the fragments of the tibia with Ilizarov's apparatus.  相似文献

Sonography was utilized to evaluate 12 patients with hypertrophy of the septum of Bertin. To confirm the diagnosis, angiography was used in 7 patients and radionuclide imaging in 2. Three sonographic characteristics were found: (1) an isoechogenic, ellipsoid mass with an echogenic linear rim of renal sinus fat; (2) contiguity of the mass with a normal-placed septum of Bertin; and (3) the occurrence of the mass effect always at the level of the emergence of the renal vein. The sonographic findings could be divided into two definite types. Type I showed moderate hypertrophy with a mass effect ranging from 1.1 by 2.3 cm to 2.0 by 3.2 cm in diameter, usually presenting with a smooth contour and discrete mass effect on the intravenous pyelogram (IVP). Type II showed severe hypertrophy with a mass effect ranging from 3.2 by 4.0 cm to 3.5 by 4.5 cm in diameter, usually presenting with a lobulated contour and irregular stretching of the calyceal system on IVP. The differential diagnosis is discussed. In conclusion, we found that sonography associated with excretory urography is an accurate method for the diagnosis of hypertrophy of the septum of Bertin.  相似文献

BACKGROUND: The purpose of this study was to determine the clinical outcome in patients in whom a displaced fracture of the posterior wall of the acetabulum had been treated by open reduction and internal fixation. METHODS: One hundred patients who had had open reduction and internal fixation of an unstable unilateral fracture of the posterior wall of the acetabulum were studied. Ninety-four patients were assessed at a mean of five years (range, two to fourteen years) after the injury. Six patients with a poor result were followed for less than two years. The functional outcome was evaluated with use of the clinical grading system adopted by Letournel and Judet with incorporation of modifications by Matta. Patient, fracture, and radiographic variables were analyzed to identify possible associations with functional outcome. RESULTS: The reduction of the fracture, as determined with plain radiography, was graded as anatomic in ninety-seven patients and as imperfect in three. The clinical outcome at the time of final follow-up was graded as excellent in fifty-five patients, very good in twenty-five, good in nine, fair in one, and poor in ten. The radiographic result was excellent in eighty-one patients, good in five, fair in four, and poor in ten. There was a strong association between the clinical outcome and the final radiographic grade. Variables identified as risk factors for an unsatisfactory clinical result included a delay of greater than twelve hours before reduction of an associated hip dislocation, an age of fifty-five years or older at the time of injury, intra-articular comminution, and osteonecrosis. CONCLUSIONS: The uncomplicated radiographic appearance and relatively simple operative approach for fractures of the posterior acetabular wall belie the risk of poor results. Prompt reduction of an associated hip dislocation is imperative. Fractures in elderly patients and those with extensive comminution are more likely to have a poor clinical result. However, a high likelihood of a long-term good-to-excellent result can be expected following anatomic reduction and internal fixation of these fractures.  相似文献

The purpose of this study was to identify those factors that influence the outcome after conservative treatment of undisplaced fractures of the fifth metatarsal. This was done with univariate analyses and, for the first time, with regression analyses of day-to-day clinical practice. Thirty-eight patients were treated with plaster and periods of no weight bearing (NWB). Their mean age was 48 years. They were evaluated using the Olerud ankle score, with analogue scales for pain and comfort, and with questions about cosmesis and wearing of shoes. Six patients sustained a Jones fracture and 32 a tuberosity avulsion fracture. The mean period of NWB was 17 days and of casting was 38 days. Three Jones fractures and all the avulsion fractures were healed at the end of treatment. After a mean of 490 days, the global ankle score was 82/100. Ten patients reported problems with shoes and nine reported cosmetic problems. The linear analogue scale for pain was 2.11/10 and for comfort 8.42/10. Gender, age, and fracture type did not affect outcome. The most significant predictor of poor functional outcome was longer NWB, which was strongly associated with worse global outcome, discomfort, and reported stiffness. NWB should be kept to a minimum for acute avulsions of the tuberosity of the fifth metatarsal.  相似文献

肌少症是一种以骨骼肌质量减少及其功能减退为主要临床表现的复杂的老年综合征。在全球其发病率逐年增高,目前已成为威胁老年人健康,影响老年人生活质量的重要危险因素。其诊断标准主要由欧洲老年人肌少症工作组、亚洲肌少症工作组、国际肌少症会议工作组提出的,通过骨骼肌质量、肌肉力量和身体活动能力进行诊断。肌少症前期仅有肌肉质量减少,肌少症期包括肌肉质量减少伴随肌肉力量下降或身体活动能力降低,重度肌少症期肌肉质量以及身体活动能力均会降低。早期对骨骼肌进行定量测量成为诊断肌少症的重要手段之一。骨骼肌定量测量方法主要有计算机X线体层摄影、磁共振成像、双能X线吸收法、生物电阻抗测量、超声等方法。计算机体X线层摄影在骨骼肌质量的研究中主要应用是作为金标准来校准其他方法;磁共振成像在肌肉定量测量中发挥着越来越重要的作用;双能X线吸收测定法和生物电阻抗方法是目前公认筛查肌少症的手段,并且有诊断的阈值,然而精确性欠佳;超声有经济、易携带、高效等优点,但其对体成分的检测价值有限。本文探讨了骨骼肌定量测量研究的现状及其进展。  相似文献
