目的：探讨手术时机的选择对股骨颈骨折患者行关节置换术后髋关节功能的影响,为临床骨科手术提供参考。方法：回顾性 分析117 例在我院接受关节置换术的股骨颈骨折患者的临床资料。根据手术时机不同,将患者分为急诊组和择期组,比较两组手 术效果,评价患者术后髋关节功能。结果：急诊组患者的手术时间、术中出血量及住院时间均优于择期手术的患者,差异有统计学 意义（P<0.01）;两组患者术后并发症的发生率无显著差异（P>0.05）;术后1 个月,急诊组患者的Harris 评分高于择期组,差异有统 计学意义（P<0.01）;术后3 个月,两组Harris评分无统计学差异（P>0.05）。结论：股骨颈骨折患者行急诊手术不但缩短手术时间、 降低术中出血量,而且术后对患者的髋关节功能影响较小,有利于恢复。     

Characteristics of sit-to-stand and gait coordination in patients with total hip replacement

Upright posture, standing up from a chair, and gait were analyzed in patients after one-sided total hip replacement and in healthy subjects (control). It was found that the patients predominantly loaded the unoperated leg when they stood quietly or rose from a chair. Subjects’ walking on a 10-m podograph treadmill showed that their walking speed was slower than that of healthy subjects and the swing phase on the side of hip replacement was longer than on the unoperated side. It was assumed that the unequal load on legs during walking, standing, and sit-to-stand performance in patients with total hip replacement was related to the sensory deficit of the artificial joint, leading to the overstrain of the unoperated leg and coxarthrosis in it.

Balloon dilatation of the aortic valve for inoperable aortic stenosis.

The place of balloon dilatation of the aortic valve in the treatment of calcific aortic stenosis is controversial. Thirty two patients (mean age 76) in whom valve replacement was contraindicated were followed up for three to 24 months (mean 8); 25 were in functional class III or IV according to the New York Heart Association''s classification. Major complications of the procedure occurred in four patients. Echocardiography and Doppler studies were performed before operation and before discharge in 28 patients, and the area of the valve was measured again six to 50 (mean 23) weeks after operation in 11 patients. The peak to peak aortic pressure gradient fell from a mean of 65 (SD 24) to 46 (20) mm Hg, but the area of the aortic valve, measured by Doppler echocardiography, in 18 patients showed a modest but significant increase, from 0.61 (0.16) to 0.74 (0.23) cm2. One month after dilatation, 29 patients were alive, of whom 17 had improved symptoms. Only two had lasting clinical benefit. Sixteen patients died, 12 of a cardiac cause. The estimated one year survival rate was 49%. Six patients underwent or required valve replacement because of persisting symptoms. In view of its limited long term efficacy balloon dilatation of the aortic valve should be used only for patients with severe symptoms whose life expectancy is limited by other disease or who are considered to be unsuitable for valve replacement. It may have a role in improving the condition of patients who present with cardiogenic shock or pulmonary oedema before valve replacement is undertaken.     

Quality of the blood sampled from surgical drainage after total hip arthroplasty

Several methods have been found to be successful in reducing the need for allogeneic transfusion among the patients undergoing total hip replacement. The purpose of this prospective study was to analyse the quality and evaluate the effect of postoperative autotransfusion on the need for allogeneic transfusion following total hip replacement. The prospective study was performed in two groups of patients undergoing total hip replacement. Before the operative procedure all patients in both groups predonated two doses of autologous blood. In GROUP 1. the system for postoperative collection and transfusion of shed blood was used. In GROUP 2. the patients underwent total hip replacement without blood salvage system. Standard suction collection sets were used postoperatively. In this group shed blood was not transfused to the patients. The samples of preoperative donated autologus blood, allogeneic blood and postoperative collected autologous blood were analysed for number of red cells, hemoglobin, hematocrit, platelets, white blood cells, values of potassium, sodium, free hemoglobin and acid base status. The postoperatively blood salvage significantly reduced the use of allogeneic transfusion among patients managed with total hip replacement (allogeneic transfusion received 12% patients in Group 1 and 80% patients in Group 2; p<0.001). The values of red blood cells are significantly lower in postoperative collected autotransfusion blood compared with preoperative collected autologous blood and allogeneic blood (p<0.001). The values of potassium and acid base status were in normal range in postoperatively collected autotransfusion blood. These values in preoperatively collected autologous blood and allogeneic blood were out of normal range; (p<0.001). In addition to reducing the risk of complications that are associated with allogeneic transfusion, postoperative blood salvage may offer benefits including reducing the need for allogeneic blood. Our study confirmed that postoperative collection and transfusion of drainaged blood is simple and safe method that significantly reduce the need for allogeneic transfusion in patients underwent total hip replacement. The blood collected and transfused postoperatively has lower values of red blood cells and normal values of potassium and acid base balance. The transfusion of this blood caused no complications in our patients.     

Cognitive and functional competence after anaesthesia in patients aged over 60: controlled trial of general and regional anaesthesia for elective hip or knee replacement.

OBJECTIVE--To determine the influence of general or regional anaesthesia on long term mental function in elderly patients. DESIGN--Prospective study of patients randomly allocated to receive general or regional anaesthesia. SETTING--The patients'' homes and a large teaching hospital in Cardiff. SUBJECTS--146 Patients aged 60 and over scheduled for elective hip or knee replacement. MAIN OUTCOME MEASURES--Scores achieved in tests of cognitive function and functional competence. RESULTS--72 Patients were allocated to receive general anaesthesia and 74 regional anaesthesia. Anaesthetic technique did not influence the duration of the operation, time to mobilisation postoperatively, requirements for analgesia after the operation, or duration of stay in hospital. Three months after the operation there was an improvement in the score for the recognition component (76 ms, 95% confidence interval 9 to 144) and the response component (82 ms, 5 to 158) of the choice reaction time in the group receiving general anaesthesia compared with the group receiving regional anaesthesia. This was the only significant difference between the two groups in the assessments of cognitive and functional competence. Eleven patients receiving regional anaesthesia and 12 receiving general anaesthesia reported that their memory and concentration were worse than before the operation, but this was not confirmed by testing. CONCLUSION--Cognitive and functional competence in elderly patients was not detectably impaired after either general or regional anaesthesia when attention was paid to the known perioperative influences on mental function.

Measuring improvement following total hip and knee arthroplasty using the SF-36 Health Survey

The aim of this study was to evaluate the impact of total hip or knee arthroplasty upon quality of life in elderly patients. The study was carried out at the Clinic for Orthopaedic Surgery Lovran on 74 total hip arthroplasty and 70 total knee arthroplasty patients. All patients had completed the Medical Outcomes Study 36-Item Short Form in the week having preceded their surgery and then again postoperatively, 2 years after. The data obtained were statistically processed at the level of physical function, role limitations due to physical problems, role limitations due to emotional problems, social function, mental health, energy or vitality, pain and general health perception, and change in health. The primary total hip arthroplasty patients showed significant improvement at all levels measured. Similarly, the primary total knee arthroplasty patients expressed significant improvement according to all the parameters but the mental health assessment. Comparison of outcomes between the two assessment groups of patients resulted in slightly superior quality of life outcomes in total hip arthroplasty patients. It can be concluded that total hip or knee arthroplasty significantly enhances the health related quality of life in elderly patients.     

Outcome of Hemiarthroplasty and Total Hip Replacement for Active Elderly Patients with Displaced Femoral Neck Fractures: A Meta-Analysis of 8 Randomized Clinical Trials

Background

Displaced fracture of the femoral neck has been a common clinical problem, especially in aged patients. However, the optimal treatment choice remains controversial. The purpose of this study is to conduct a systematic review of randomized clinical trials assessing the results of hemiarthroplasty and total hip replacement in patients undergoing either alternative using meta-analysis.

Methods

A literature search for randomized clinical trials was conducted through Medline, Embase and Cochrane library between 1969 and 2013 with no restrictions. Additional relevant articles were referred as source of information by way of manual searches on major orthopedic journals. Upon the search, two authors independently evaluated study quality and relevant data was extracted.

Results

A total of 8 studies with 983 patients were included in this meta-analysis. After pooling the available data, a significant dominance of Harris hip score was found for total hip replacement compared with hemiarthroplasty (SMD: −7.11, 95%:−10.70,−3.53) one year postoperatively and the advantage kept over (SMD: −6.91, 95%:−12.98, −0.85) two years after surgery. A trend toward a higher dislocation rate was found in total hip replacement group (RR: 0.46, 95%: 0.21, 1.02), of which the difference was considered insignificant. The risk of revision in group hemiarthroplasty appeared to be more than two folds higher than that after total hip replacement (RR: 4.14, 95%CI: 2.09, 8.19).

Conclusion

Even though there is a higher rate of dislocation after total hip replacement, this disadvantage could be accounted for, on the basis of a better functional score and the lower revision rate. However, from the results, it stands to reason that total hip replacement should be strongly suggested in elderly active patients with femoral neck fracture.
