封闭治疗颞下颌关节功能紊乱效果分析

目的颞下颌关节功能紊乱的封闭治疗效果分析。方法将2008年7月至2010年6月我院收治的54例非创伤性颞下颌关节功能紊乱患者,随机分组,分别采用封闭治疗和电针治疗,并对比疗效。结果观察组通过封闭治疗痊愈21例、显效5例、无效1例,痊愈率达77.78%,总有效率达96.30%。对照组通过电针治疗痊愈14例、显效9例、无效4例,痊愈率达51.85%,总有效率达85.19%。观察组治疗痊愈率和有效率均明显高于对照组,2组差异具有显著性(P<0.05)。结论在颌关节功能紊乱的治疗中封闭治疗效果显著,值得推荐。

Clinical observation on tuina plus Baixiao moxibustion for temporomandibular joint dysfunction syndrome

Objective:To observe the clinical effect of tuina plus Baixiao moxibustion in the treatment of temporomandibular joint dysfunction syndrome(TJDS).Methods:A total of 70 TJDS patients who met the inclusion criteria were randomized into an observation group and a control group by flipping a coin,with 35 cases in each group.Patients in the observation group were treated with tuina plus Baixiao moxibustion,while patients in the control group received oral intake of diclofenac potassium(75 mg/pill),1 pill after every dinner.Both tuina and Baixiao moxibustion were done once a day during treatment.The therapeutic evaluation was evaluated after 10 treatments in both groups.The maximum mouth opening distanee and visual analog scale(VAS)were observed before and after treatment,and the therapeutic efficacy was also compared.Results:After treatment,the maximum mouth opening distanee and VAS improved in both groups(all P<0.05);both items in the observation group were superior to those in the control group(both P<00.05).The total effective rate was 91.4%in the observation group,versus 74.3%in the control group,and the between-group comparison of the total effective rate showed statistical significanee(P<0.05).Conclusion:Tuina plus Baixiao moxibustion can effectively improve TJDS patient's temporomandibular joint function and alleviate pain,with better efficacy than oral intake of diclofenac potassium.

Spiral CT arthrography of multiplanar reconstruction and virtual arthroscopy technique in diagnosis of knee with internal derangements

Objective:To evaluate the values of spiral CT arthrography with multiplanar reconstruction and virtual arthroscopy technique i n diagnosis of internal derangements of the knee. Methods:Ten bovine knees were used for experiment. The menisci , anterior and posterior cruciate ligaments and cartilage of these 10 bovine kne es were injured with a hook. Each of the joints was injected with 100 ml air, th en soon scanned with a PQ6000 spiral computed tomography scanner. The data obtai ned was input into the work station, and multiplanar reconstruction technique wa s used to illustrate lesions in the knees. The results of CT diagnosis were comp ared to those found by gross inspection of the specimens. Clinically, 10 knees o f 9 patients diagnosed as internal derangement were evaluated with the same meth od after 50-70 ml air was injected into each of the joints. Nine months later, the data of 2 patients were used for CT endoscopy reconstruction. The results we re compared with intraoperative findings. Results:Experimentally, the sensitivity and specificity were 88.9 % and 93.9 % by detection of meniscal abnormalities, 85.7 % and 10 0% by detection of cruciate ligament lesions, and 72.7 % and 100% by detectio n of cartilage damage, respectively. Clinically, the sensitivity and specificity were 90.0 % and 95.0 % by detection of meniscal lesion. As to ligament, t he figures were 85.7 % and 100% respectively. Images of virtual arthroscopy s imulated the images of real arthroscopy. Conclusions:Spiral CT arthrography of multiplanar reconstructi on technique offers fine images of internal structures of the knee, with clear b order and internal structure. It is an accurate method for detecting meniscal, cruciate and collateral ligament and cartilaginous lesions that cause internal d erangement of the knee. Virtual arthroscopy technique is a hopeful method for de tecting reasons of derangement of the knee.
