目的比较不同髋关节疾病行THR后的疗效,为临床上治疗髋关节疾病行THR后的疗效及预后判断提供依据。方法对2000年1月至2007年1月在我科行首次THR的126例患者按诊断分为4组:新鲜股骨颈骨折(fres hfemoral neck fracture,FFNF)、陈旧性股骨颈骨折(old femoral neck fracture,OFNF),骨性关节炎(osteoarthritis,OA),股骨头坏死(femoral head necrosis,FHN)。依据诊断进行回顾性分析,使用Harris评分对THR术后疗效评估,初步评价不同髋关节疾病行THR术后的疗效。结果新鲜股骨颈骨折组由术前平均21.6分恢复到术后平均82.5分(平均63.5岁);陈旧性股骨颈骨折组由37.7分恢复到90.6分(58.9岁);骨性关节炎组由35.0分恢复到81.6分(59.5岁);股骨头无菌性坏死组由4.07分恢复到86.3分(56.9岁);骨性关节炎患者中的原发性骨性关节炎组由29.4分恢复到87.8分(58.7岁)。结论 THR正逐渐成为目前治疗严重髋关节疾病的最有效术式,严格实施术后随访有利于提高和改进THR手术水平、改进假体选择和设计、正确评估手术预后。 相似文献

INTRODUCTION
Patients with rheumatoid arthritis (RA) and osteoarthritis (OA) may require total hip replacement (THR) or total knee replacement (TKR). The present study aimed to compare the demographic characteristics and medical costs of RA and OA patients from Taiwan who underwent either THR or TKR.METHODS
The medical records of patients who had undergone THR or TKR from 1 January 1996 to 31 December 2010 were obtained from the Taiwan National Health Insurance Research Database (NHIRD). In all, we found 49 and 146 RA patients who received THR and TKR, respectively, and 1,191 and 6,574 OA patients who received THR and TKR, respectively. The gender, age, Charlson comorbidity index (CCI), hospital grade, age at registration in the catastrophic illness dataset, and medical utilisation costs of the different groups were compared.RESULTS
There were statistically significant differences in age, CCI score, drug costs and surgery costs between RA and OA patients. Joint replacement incidence was lower in RA patients than in OA patients, and among patients who underwent THR, total medical costs incurred were higher for RA patients than OA patients. RA patients who underwent THR incurred a significantly greater total medical utilisation cost in the outpatient department (3 months before surgery and 12 months after surgery) than OA patients who underwent THR.CONCLUSION
Analysis of Taiwan NHIRD with regard to patients who had undergone either THR or TKR indicated that RA patients were younger than OA patients, and that significantly more medical resources were used for RA patients before, during and after hospitalisation for these procedures. 相似文献3.

The concentration of substrate expressed as hypoxanthine capable of reacting with xanthine oxidase to release superoxide free radicals (O2-) was measured in control and Dupuytren's contracture palmar fascia. In Dupuytren's contracture palmar fascia the concentration of hypoxanthine was six times that of control and was greatest in "nodular" areas. Xanthine oxidase activity was also detected in Dupuytren's contracture palmar fascia. These results suggest a greater potential for hypoxanthine-xanthine oxidase generated oxygen free radical formation in Dupuytren's contracture than in control palmar fascia. Production of free radicals may be an important factor in the pathogenesis of Dupuytren's contracture. The benefit of allopurinol in the management of Dupuytren's contracture and other fibrotic conditions may thus be explained, as allopurinol binds to xanthine oxidase and prevents release of free radicals. 相似文献

Thyroid hormone resistance (THR) is a rare syndrome of reduced end organ sensitivity. Patients with THR have elevated serum free thyroxine (FT4), free triiodothyronine (FT3), but normal or slightly elevated serum thyrotropin values. The characteristic clinical feature is goitre without symptoms and metabolic consequences of thyroid hormone excess. THR can be classified on the basis of tissue resistance into pituitary, peripheral or generalised (both pituitary and peripheral) types. Mutations in the TRbeta gene, cell membrane transporter and genes controlling intracellular metabolism of thyroid hormone have been implicated. THR is differentiated from thyroid stimulating hormone (TSH) secreting pituitary adenoma by history of THR in the family. No specific treatment is often required for THR; patients with features of hypo- or hyperthyroidism are appropriately treated with levo-triiodothyronine (L-T3), levo-thyroxine (L-T4), dextro-thyroxine(D-T4) or 3,3,5 triiodo-thyroacetic acid (TRIAC). The diagnosis helps in appropriate genetic counselling of the family. 相似文献

In the absence of thromboprophylaxis, venous thromboembolism (VTE) affects about 50 to 80% of the patients after total hip replacement (THR), total knee replacement (TKR), or hip fracture surgery. Since stratification of patients in those who will become symptomatic and those who will not, is not possible, primary high risk thromboprophylaxis should be provided to all patients undergoing major orthopedic surgery of the lower extremity. Various non-pharmacologic and pharmacologic thromboprophylactic measures have been evaluated. With regard to pharmacologic thromboprophylaxis unfractionated heparin has now almost completely been replaced by low molecular weight heparin (LMWH) for VTE prophylaxis. The use of acetylsalicylic acid for thromboprophylaxis in patients undergoing major orthopedic surgery of the lower extremities is not recommended. The optimal beginning of LMWH thromboprophylaxis is either 2 hours preoperatively or 6 to 8 hours postoperatively. Extended thromboprophylaxis (beyond 7 to 10 days after surgery) is recommended for high-risk patients. New antithrombotics, such as fondaparinux or (xi)melagatran, significantly reduce the risk of asymptomatic but not of symptomatic VTE compared to LMWH. In the light of other potential side effects (e.g., an increased bleeding risk) and high costs the role of these new drugs in the prophylaxis of VTE in patients undergoing major orthopedic surgery of the lower extremities remains to be established. 相似文献

Background
With an aging society and raised expectations, joint replacement surgery is likely to increase significantly in the future. The development of postoperative complications following joint replacement surgery (for example, infection, systemic inflammatory response syndrome and deep vein thrombosis) is also likely to increase. Despite considerable progress in orthopaedic surgery, comparing a range of biological markers with the ultimate aim of monitoring or predicting postoperative complications has not yet been extensively researched. The aim of this clinical pilot study was to test the hypothesis that lower limb orthopaedic surgery results in changes to coagulation, non-specific markers of inflammation (primary objective) and selective clinical outcome measures (secondary objective).Methods
Test subjects were scheduled for elective total hip replacement (THR) or total knee replacement (TKR) orthopaedic surgery due to osteoarthritis (n = 10). Platelet counts and D-dimer concentrations were measured to assess any changes to coagulation function. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were measured as markers of non-specific inflammation. Patients were monitored regularly to assess for any signs of postoperative complications, including blood transfusions, oedema (knee swelling), wound infection, pain and fever.Results
THR and TKR orthopaedic surgery resulted in similar changes of coagulation and non-specific inflammatory biomarkers, suggestive of increased coagulation and inflammatory reactions postoperatively. Specifically, THR and TKR surgery resulted in an increase in platelet (P = 0.013, THR) and D-dimer (P = 0.009, TKR) concentrations. Evidence of increased inflammation was demonstrated by an increase in CRP and ESR (P ≤ 0.05, THR and TKR). Four patients received blood transfusions (two THR and two TKR patients), with maximal oedema, pain and aural temperatures peaking between days 1 and 3 postoperatively, for both THR and TKR surgery. None of the patients developed postoperative infections.Conclusions
The most noticeable changes in biological markers occur during days 1 to 3 postoperatively for both THR and TKR surgery, and these may have an effect on such postoperative clinical outcomes as oedema, pyrexia and pain. This study may assist in understanding the postoperative course following lower limb orthopaedic surgery, and may help clinicians in planning postoperative management and patient care. 相似文献16.
