羟基磷灰石涂层人工股骨柄的临床应用

自１９８９年１２月～１９９３年１１月，共收治各类髋关节病１４例（１５髋），均行ＦＵＲＬＯＮＧ羟基磷灰石（ＨＡ）涂层人工髋关节置换术。术后平均随访３２个月，髋关节功能按Ｈａｒｉｓ评分结果为平均９５分。无患肢疼痛和其它不适症状，亦无术后并发症发生。Ｘ线结果显示，股骨侧假体无松动、下沉表现，周围未见明显透亮线。术后３个月假体表面出现增生性骨反应，并在术后３～４年内逐渐增加。无明显骨萎缩表现。结合实验及临床研究结果，证明此种髋假体应用的短期疗效令人满意，其长期疗效尚有待进一步观察。

Nonoperative treatment ofacromioclavicular joint injuries

Nonoperative treatment is generally the choice for Type I and II acromioclavicular (AC) joint injuries. The situation issomewhat more controversial when Type III AC dislocations are considered, particularly with respect to athletes and heavy laborers. A number of recent studies have supported conservative treatment in these groups. There is general consensus as to the need for surgical intervention for Type IV, V, and VI AC injuries. Integral to any form of management, nonoperative or operative, is a rehabilitation program that addresses range of motion, strength, and neuromuscular control. We describe our program, which is divided into four phases: (1) Pain control and immediate protected range of motion and isometric exercises; (2) strengthening exercises using isotonic contractions and proprioceptive neuromuscular facilitation (PNF) exercises; (3) Unrestricted functional participation with the goal of increasing strength, power, endurance, and neuromuscular control; and (4) return to activity with sport specific functional drills. An athlete is ready to return to competitive sports once the following criteria are met: full range of motion (ROM), no pain or tenderness, satisfactory clinical exam, and demonstration of adequate strength on isokinetic testing. The unique considerations in a throwing athlete with an AC injury are also addressed. The primary goal of the nonoperative treatment protocol is to return the athlete to full activities as quickly and as safely as possible.

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

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.
