In this paper, the orientation of the instantaneous center of rotation (ICR)with respect to the ankle joint was determined by using the fitting of a third degree spline function. According to the definition of arm of force (AF)of muscle, the AF at ICR of triceps surae corresponding to esch rotation angle of ankle joint were calculated. Finally, with the ICR position and the data of AF,a nonlinear regression equation of rotation angle of ankle joint was established using variance analysis and nonlinear regressive...

Chiari pelvic osteotomies in 36 patients were performed.They were suffered frorn hip dysplasia,coxa plana,etc.The average following-up was four years and four months in the thirty two hips.Postoperative X-ray plates showed all the cases healed with good congruity and coverage between the acetabulum and the femoral head.The mean center-edge angle increased 20 degrees after operation.The operation could increase the contact area and thus decrease the contact pressure,intra-osseous pressure and then relieve the pain of hip.The favourable biomechanics changes after the operation were discussed in detail.Adult hip dysplasia,coxa plana,femoral head necrosis,osteoarthrosis of the hip were recommoned for this operation.

本文报告应用Chiari骨盆截骨术治疗髋臼发育不良、扁平髋等36例41个髋。32个髋平均随防4年4个月。优良者27个髋,占84.37%。术后X线片显示,截骨均获骨性愈合,髋臼对头覆盖完全,头臼相称。髋臼发育不良者,CE角平均增加20°。作者分析此术式后认为:Chiari手术能增加髋臼面积,减少股骨头单位压强,截骨内移后能增加肌力臂,减少重力臂,从而减少髋关节的载荷,降低关节内压及髂骨髋内压,有利于缓解“休息痛”。为此提出成人先天性髋臼发育不良、扁平髋、股骨头无菌坏死以及髋的骨关节炎病人适合行此手术。

Objective To investigate pathomechanics of traumatic scapho-lunate dissociation and kinetic requirement of its treatment. Methods Seven fresh frozen cadaver upper extremity specimens were used. Excursions of the primary wrist movements were measured during wrist flexion, extension and radioulnar deviation. The study was performed in 4 stages: intact wrist, scapho-lunate interosseous ligament (SLIL) sectioning, moderate and severe scapho-lunate gaps. Moment arms were calculated according to relationship between...

Objective To investigate pathomechanics of traumatic scapho-lunate dissociation and kinetic requirement of its treatment. Methods Seven fresh frozen cadaver upper extremity specimens were used. Excursions of the primary wrist movements were measured during wrist flexion, extension and radioulnar deviation. The study was performed in 4 stages: intact wrist, scapho-lunate interosseous ligament (SLIL) sectioning, moderate and severe scapho-lunate gaps. Moment arms were calculated according to relationship between tendon excursion and joint motion. Results Moment arms of the radial extensors increased signif- icantly after SLIL sectioning. Moment arms of the flexor carpi radial is tendon increased significantly in all stages of scapho-lunate dissociation. During radioulnar deviation, moment arms decreased significantly in all the tendons except flexor carpi radialis increased. conclusion integrity of the SLIL and normal scapho-lunate gap play an important role in wrist kinetics. Changes of the wrist motor tendons may be the pathogenesis of carpal collapse and joint degeneration. The study also indicates that restoration of wrist kinetics should be a goal in treatment of scapho-lunate dissociation.

通过生物力学研究,探讨腕创伤性舟月骨分离及临床并发症的生物力学机制和治疗要求。方法 采用7只新鲜冷冻尸体上肢,分别在腕关节完整、舟月骨间韧带切断、中度及重度舟月骨间隙增大四个实验阶段测定腕关节屈伸和尺桡偏运动时,腕主要运动肌腱的滑动距离,并根据滑动距离和关节运动角度与力臂之间的关系计算肌腱力臂。结果 在舟月骨间韧带切断后腕屈伸运动时桡侧伸腕肌键的力臂明显增大;在舟月骨间韧带切断及舟月骨间隙增大时,腕屈伸或尺桡偏时桡侧腕屈肌力臂显著增大;在腕尺桡偏时,除桡侧腕屈肌力臂显著增大外,其余显著减小。结论 舟月骨间韧带的完整及舟月骨间隙对腕运动肌腱的功效有重要意义,腕肌腱力臂变化可能成为腕塌陷及退变的动力学原因,提示恢复正常腕关节动力学应成为舟月骨分离治疗的目标。
