对129例脊柱侧凸患者,采用哈氏捧(Harrington 氏捧)矫正侧凸畸形,同时取异体冷冻干燥骨加少最自体骨作脊柱融合术。有57例术后6月~3年的患者作了随访,其中52例无严重并发症,植骨愈合良好:2例有融合处假关节形成;1例哈氏棒断裂;2例在骨钩处形成滑囊炎并发感染。植入球干骨的效果相当于自体骨移植,来发生感染和全身性免疫反应。  相似文献

本文通过对20名青年男女平地常速行走时的电影摄影,计算出单肢负重期踝关节力,胫前肌力、小腿三头肌力的平均峰值,分别为4.79BW,0.9BW,3.51BW,各峰值分别出现于单肢负重的晚期、早期和晚期。本文还结合行走时各峰值的出现时间,分析了肌肉对踝关节稳定性和功能所起的作用和该肌瘫痪后所造成的结果。文中求得的数据,在设计和制作踝关节假体及选择材料时均甚重要,而且还是踩关节病理力学分析时有用的基础数据。  相似文献

1985和1986年共使用改良Luque装置治疗了36例脊柱侧凸。矫正装置由L形棒、钢丝和钮扣组成。钢丝不通过椎板下方而经由棘突根部穿过,从而减低了手术难度,缩短手术时间并有利于防止脊髓损害。钮扣的应用扩大了着力点的接触面积。L形棒可单根、双根或与Harrington氏棒合用。全组平均矫正率为34.2%。文内详细讨论了手术适应证、胸椎生理后凸的维护和后凸畸形的矫正问题以及获得手术成功的要点。  相似文献

A S9-2 computerized gait analysis system developed by us is reported. The advantages of the system are: synchronous measurement of the forces, angles and time parameters; high efficiency, accuracy and good repeatability; low cost and easy to operate. A three dimensional analysis of the foot-ground reaction forces of 41 normal subjects during level walking was carried out by the S9-2 system and a series of normal values of parameters and characteristic curves were obtained. The mechanism of formation of the parameters and curves and the sex influence were investigated and discussed. In old subject, before the development of "cautious gait", most values of the parameters did not differ significantly from those of the young subjects, except that the centre of gravity of the body crossing the hip earlier with a slight decrease in the medio-lateral balance capacity.  相似文献

Rotatory chiropractic is one of the key manipulations in the treatment of low-er backache. The present paper reports the kinematic changes in the posterior element oflumbar spine during rotatory manipulation, using motion segments of lumbar spine fromfresh cadavers as specimens and an electromechanical system for the measurements. Theanalysis of the angle-displacement curve and the load-angle curve reveals that rotatorychiropractic is a kind of complicated 3-D. 6-degree-of-freedom motion. Correctmanipulation may adjust the volume of the nerve root canal and relax the articulation be-tween the upper and lower joint processes so as to relieve the adhesion of the enclosuresin the nerve root canal and relieve the adhesion of the facet joints, and bring aboutimprovement of local circulation and amelioration of symptoms.  相似文献

Foot pressure measurements were performed during standing and level walkingon a series of 30 normal subjects (15 males, 15 females, a total of 60 feet) with amean age of 37.6 yrs and a mean body weight of 66.3 kg. A significant difference wasfound in the peak pressure under the second metatarsal head between males and femaleswith females showing higher pressures than males daring walking (P<0. 01). The meanpeak pressure and standard deviation for all 7 areas selected for 30 adult subjects duringstanding and walding were obtained. The rise time to peak pressure at each selected areafor walking was recorded and analysed. The practical application and clinical significanceof these data were also discussed.  相似文献

We evaluated the results of distal osteotomy of shortening the first metatarsal head with internal fixation of shape memory metal compression staple for hallux valgus in 26 feet of 17 women with a mean age of 41.0 years (30-65 years). The time for return to light work averaged 18.2 days, and to full work and normal walking 40.3 days after the operation. 16 patients (25 feet) had complete pain relief. Only in one foot, the pain was transferred under the 2nd metatarsal head. The appearance of the feet was markedly improved and the width of the forefeet was decreased by a mean of 0.92 cm after the operation. All of the patients were statisfied with the appearance of their feet. Radiographic analysis of feet showed that all osteotomies united, and the average angle of hallux valgus was improved from 30.1 ° to 16.0 ° , with the mean intermetatarsal angle of 11.2 ° -6.5 ° . No external fixation of plaster splintage was used and the distal fragment during healing of the osteotomy was stable. The time of bon  相似文献
