Methods: The epoxy resin three dimensional photoelasticity patellar models were made by precise moulding, and were fixated by nitinol patellar concentrator (NT-PC), tension band and wire circle respectively. The patellar models with frozen stress stripes were put into the polarized light field and the stress distributions were compared. As for the model fixated by NT-PC, by dividing layer, photographing and tracing, we used the iterative method to calculate the stress value of every internal node of the epoxy resin patellar model, and the character of stress was analyzed. Results: An overall stress field was yielded when the patellar model was fixated by NT-PC, and the stripes were more than that of tension band model and wire circle model, which have only few stress stripes in the fixated layers. Further analysis indicated that there were continuous fixated stresses in the facies articularis and distal pole of patella, and the character of stresses produced by NT-PC were mainly in longitudinal direction, then in transverse direction. The shearing stresses were small. Conclusion: The initiative and continuous memorial stress of NT-PC and its overall stress distribution character are the essence of NT-PC distinguished with tension band and wire circle in treating patellar fractures. The stress character produced by NT-PC is good for the stability of fracture site and prompts fracture healing.展开更多

Methods: A total of 90 cases of knee osteoarthritis were evenly randomized into Ba-He technique group (observation group) and common technique group (control group), with 45 cases in each group. Zusanli (足三里 ST 36), Heding (鹤顶 EX-LE 2) and Dubi (犊鼻 ST 35 ) were punctured respectively in Ba-He technique and common technique in the two gr oups. The therapeutic effects of the two groups were compared after one course o f treatment (10 sessions) in accordance with Japanese assessment criteria for kn ee-joint functions. Results: After treatment, among the 74 and 7 1 affected knees in the observation and control groups, the therapeutic effect was excellent in 42 (56.8%) and 26 (36.6%) knees, fine in 14 (18.9%) and 20 (28.2%), OK in 10 (13 .5%) and 11 (15.5%), and poor in 8 (10.8%) and 14 (19.7%) respectively. The ther apeutic effect of the observation group was significantly better than that of co ntrol group (P<0.01). Conclusion: The Ba- He technique of acupuncture applied to the above-mentioned three acupoints exerted remarkable therapeutic effect for k n ee osteoarthritis, which is obviously better than that of the common needling te chnique.展开更多

It is a common and frequently occurring disease affecting the health and life quality of old people. In recent years, acupuncture treatment of knee osteoarthritis with satisfactory therapeutic results has been repeatedly reported,2-3, 5-6 but there has been few report on the observation of long-term therapeutic effects after treatment. With acupuncture as the main therapy, 109 cases of knee osteoarthritis were treated in this series. 91 cases with good therapeutic results were followed up for 6 months. A report is presented in the following.展开更多
