Arthroscopic distal clavicle resection

The acromioclavicular joint is a potential source of pain in the shoulder. There are a variety of disorders that can affect this joint, including distal clavicle osteolysis, posttraumatic arthritis, osteoarthritis, and rheumatoid arthritis. Nonoperative treatment for this condition with nonsteroidal medication and activity modification can alleviate the pain. When conservative treatment is exhausted, surgical resection of the distal clavicle is often necessary. Arthroscopic resection of the distal clavicle preserves the acromioclavicular ligaments to prevent postoperative distal clavicle instability. The procedure is performed in either the beach chair or lateral position and requires the use of a shaver, electrocautery, and a burr for soft tissue and debridement and bone resection.     

关节镜下股骨单隧道与双隧道重建后十字韧带的疗效分析

目的分析比较关节镜下单束单隧道与双束股骨双隧道重建后十字韧带(PCL)术后的临床效果。方法1999年1月～2001年12月,采用单束前外束重建法重建PCL 18例,男14例,女4例;年龄18～50岁,平均35.5岁;右膝12例,左膝6例。移植物为骨-髌腱(中1/3)-骨的11例,半腱肌腱和股薄肌腱的7例。于PCL股骨附着点解剖中心的稍前方钻取股骨隧道,屈膝70°,拉紧并固定移植物。2000年1月～2002年12月,采用双束股骨双隧道法重建PCL12例,男10例,女2例;年龄21～47岁,平均33岁;右膝9例,左膝3例。移植物为半腱肌腱和股薄肌腱的7例,一端带髌骨块的股四头肌肌腱的5例。将肌腱编织分为两束。于股骨侧钻取双隧道。两束分别于屈膝70°和0°时拉紧并固定。结果采用前外束重建法的18例患者平均随访23个月,采用双束股骨双隧道重建法的12例患者平均随访17个月。前外束重建组与双束股骨双隧道重建组随访时的Lysholm评分分别为(92.4±3.7)分和(94.3±3.4)分,两组间差异无显著性(P>0.05)。屈膝0°和30°时,前外束重建组的胫骨后移距离是(5.9±0.4)mm和(6.2±0.5)mm,双束股骨双隧道重建组是(3.5±0.3)mm和(4.0±0.4)mm,两组间差异有显著性(P<0.05);屈膝60°和90°时,两组胫骨后移距离差异无显著性(P>0.05)。结论双束股骨双隧道重建PCL的方法优于前外     

少年儿童颞下颌关节紊乱综合征的错雅(牙合)特征

①目的 探讨少年儿童颢下颌关节紊乱综合征(TMJD)的错拾特征。②方法 用一般口腔检查工具对青岛地区的550例TMJD病人进行拾检查。③结果 80．0％的病人有不同程度的错He，其中个别牙齿错位所占的百分率最高(42．4％)，其次为高度不调、长度不调和宽度不调；不同牙龄期病人错He特征不同。④结论 本研究结果可以作为TMJD早期正畸治疗以及治疗时对错He分析和诊断的参考。     

A Comparative Study on the Close Reduction of Arytenoid Dislocation under Indirect and Direct Laryngoscope

To assess the curative effects of different reduction techniques on the dislocation of cricoarytenoid joint caused by intubation,indirect laryngoscope (IL) and direct laryngoscope (DL) were utilized for the closed reduction of the displaced arytenoid under local anesthesia.23 patients who underwent the reduction for dislocated arytenoid under IL or DL from January 1991 to June 2001 were reviewed.The data were collected on the duration of the laryngeal injury,times of receiving reduction,side-effects after the treatment and the period for voice to returen to normal.The relationship between the duration of the laryngeal lesion and the period of the voice rehabilitation was examined.13 patients received the reduction under IL and 10 patients under DL,Except the times of the reduction,which showed significant difference,no differences were found between IL group and DL group in the course and the period of voice rehabilitation,as well as sore throat after the manipulation.The patients‘ voice recovery was positively related to their course of disease in both IL and DL group.It is coucluded that the recovery of normal voice is obviously affected by the duration of arytenoid dislocation.The reduction under Il is as effective as under DL in the treatment of arytenoid dislocation.Reduction by DL is better suit the patients with long time course of disease.     

带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎

目的：阐明带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎的疗效。材料和方法：对４２例４８髋晚期类风湿性髋关节炎病人采用以旋股外侧血管降支为蒂的股前外侧筋膜瓣移植行患髋成形术。结果：术后随访４～１０．５年，平均４．５年，髋关节活动范围术前平均１６．５°，术后２２８．６°，按照Ｃｈａｒｎｌｅｙ和吴之康人工髋关节置换术后的疗效评定标准，优良２９髋、很好１３髋、好６髋，尚可、差、很差无。结论：患者年龄在１５～４０岁之间为合适的治疗年龄。与人工髋关节置换术相比，本方法对髋关节正常结构破坏小；一旦手术失败仍可选用其它治疗方法弥补；且并发症少、费用低、远期效果好。     

Neoplastic involvement of the sacroiliac joint: MR and CT features

The radiological findings in five patients with pelvic sort tissue neo plasms directly involving the sacroiliac joint, are described. All patients had Computed Tomography (CT) examinations, two of the patients also having Magnetic Resonance Imaging (MRI). The role of imaging in this uncommon entity is discussed as well as the importance of making this diagnosis, thereby excluding unilateral sacroiliitis. The therapeutic implications of this diagnosis relate to local neural involvement, especially the sciatic nerve, and the fact that involvement of the sacroiliac joint by tumors significantly compromises chances of a successful surgical outcome. The role of MR in this condition is not yet certain, but it may prove to be the method of choice in view of its excellent depiction of skeletal neo plasms.     

用带血管的腓骨近段重建桡腕关节的临床研究

用绘图法对１５具尸体１５对腓骨小头的胫腓关节面及桡骨腕关节面进行了解剖学的对比研究，观察关节面形态，测量其长径、横径、关节面倾斜角度、曲率半径，发现腓骨小头的胫腓关节面和桡腕关节面解剖相似。在此基础上，临床应用带血管腓骨近段移植重建桡腕关节４例收到良好的疗效，根据Ｇｒｅｅｎ评分标准，腕关节评分为７０～８５分。     

膝关节 Q 角变化规律的实验研究

本研究利用精密三维位移测读仪，研究分析了Ｑ角的变化趋势，以及对髌股关节运动的影响。研究结果表明，Ｑ角是一空间夹角，随屈膝角的增大而增大。力线在平面上的投影所呈的平面夹角Ｑｐ也就是通常所指的Ｑ角，在屈膝１５°左右达最大，而在９０°左右达最小。整个屈膝过程中，ＱＰ在５°－１５°之间变化，变化幅度达１０°左右。
