经尿道前列腺电切术后膀胱颈挛缩多因素分析

目的 :对经尿道前列腺电切术 (TURP)后膀胱颈挛缩 (BNC)发生的各种可能因素进行分析 ,探讨减少该并发症的途径。　方法 :对 10 17例行TURP患者中发生BNC的 2 4例进行统计学分析 ,在手术方法、前列腺电切重量、单位时间前列腺组织电切重量、置管时间、高频发生器类型及有无糖尿病、尿潴留及前列腺炎等方面进行比较 ,了解其可能发生的因素。　结果 :TURP术后BNC发生率明显高于开放手术病例 ,小前列腺、单位电切时间长、高频发生器功率大及术前前列腺炎患者易发生BNC(P <0 .0 5 ) ,而术前尿潴留、糖尿病及术后置管时间对BNC发生无明显影响 (P >0 .0 5 )。　结论 :小前列腺、前列腺炎及电流损伤是发生BNC的重要因素 ,患者的选择及熟练精确的电切技术可减少BNC的发生。     

外固定器治疗肱骨外科颈粉碎骨折

肱骨近端粉碎性骨折的治疗目前仍是骨外科的一大难题，手法复位后以石膏或夹板固定常不能持续复位，影响肩关节功能；尺骨鹰嘴牵引，卧床时间长，老年人易出现其他并发症。自2001年6月-2003年6月，我们应用透视下闭合复位或切开复位外固定器固定治疗肱骨近端粉碎骨折20例，取得满意疗效。

浮肩损伤的治疗方法选择

目的探讨浮肩损伤治疗方法的选择。方法52例浮肩损伤患者行非手术治疗15例,手术治疗37例,并对其进行回顾性对比分析。采用Herscovic i功能评估方法;影像学检查主要在肩关节正位X线片上测量盂极角(GPA)。结果48例获8个月~16年随访。非手术组:随访13例,优2例,良3例,可2例,差6例;7例GPA>20°,6例GPA<20°。手术组:随访35例,其中单纯锁骨或肩锁关节固定26例:优16例,良3例,可5例,差2例;20例GPA>20°,6例GPA<20°。肩胛颈、锁骨联合手术9例:优4例,良2例,可2例,差1例;8例GPA>20°,1例GPA<20°。结论浮肩损伤手术治疗明显优于非手术治疗,且多数病例可采取单纯固定锁骨或肩锁关节的手术方案,但对于锁骨骨折合并同侧严重移位的肩胛颈骨折宜采用联合手术治疗,以重建肩关节稳定,促进关节功能的早期康复。     

不同钉位布局影响股骨颈骨折内固定效应的生物力学研究

目的:观察应用多枚钉内固定治疗股骨颈骨折时采取不同钉位布局对骨折断端固定效应的影响,为临床操作中寻求最佳钉位布局奠定基础。方法:通过特制壮年人体尸骨股骨颈骨折模型,进行直视下解剖复位后,分别应用3钉倒三角形、3钉正三角形和双钉平行3种不同钉位布局内固定方法完成内固定。在生物力学万能试验机上进行轴向压缩和扭转实验,观察不同生物应力下断端相对的位移距离、轴向刚度、水平剪切刚度和扭转强度等项目,取得试验数据后经统计学处理,进行组间对比,观察其差异的显著性。结果:在3种钉位布局的内固定方法之中,以股骨矩核心下2～3mm处进钉位为下位顶点的倒三角形钉位布局能获得最坚强的固定效应,相同应力下其位移距离最小而各项刚度最大;而股骨矩核心上位和中下位双钉固定法固定效应最差,表现为相同应力下位移距离最大和各项刚度最小。结论:尽可能选择以股骨矩核心下2～3mm处进钉位为下位顶点的倒三角钉位布局法,尽可能减少应用双钉位布局法。     

The role of primary total hip replacement for the treatment of the displaced femoral neck fractures

Summary The management of displaced intracapsular fractures of the hip is still controversial because of the high incidence of complications after internal fixation or hemiarthroplasty. To avoid some of these complications we have used primary total hip replacement for independently mobile patients over 65 years of age.Of 49 patients who were interviewed an average of 4.6 years after total hip replacement, 81.6% had excellent or good results as assessed by the Harris Hip Score. At that time two hips had been revised and another converted to Girdlestone due to deep infection. The survival of the prostheses was at 5 years 91.3%.It is concluded that total hip replacement is an established method of management for a selected group of patients with this injury, but further prospective studies are needed in order to define the groups of patients that benefit the most.     

Tension neck and evaluation of a physical training course among office workers in a bank corporation

The purpose of this study was to investigate the effects of a physical training course in a group of patients (n=74) suffering from chronic tension neck. All participants in the course were employed by a bank corporation in Helsinki, Finland. A comparable control group (n=77) consisted of office workers with tension neck from the same bank corporation who did not attend any training course. The outcome was analysed 6 months after the course. Pain and disability in the neck and shoulder region did not vary significantly between the group which participated in the training course and the control group. The experimental group had increased the amount of physical workout compared to the control group (83.7% vs 69.0%, P = 0.0448). Also, regarding the frequency of relaxation and stretching exercises the two groups differed significantly: the experimental group had continued to perform exercises more often (P= 0.0434). The frequency of sick leave days did not significantly differ between the groups, but the office workers in the experimental group had more periods of extended sick leave (> 10 days) and the controls had more frequent short sick leaves. The experimental group did increase their physical workout significantly compared with the controls, but no differences were detected regarding pain and disability. In order to gain more benefit more attention should be paid to the educational part of the training courses in order to enhance the patients'self-care abilities. Also, strategies to alleviate psychosocial problems and organized relaxation exercises could decrease muscle tension in the neck in office workers.
