小腿

Objective To establish an effective technique in reservation and function reconstruction of a leg, in which all the muscles except gastrocnemius necrosed induced by the delayed necrosis of all the intermuscular vessels, the foot was linked only by skin, fascia and tibia, Methods The leg was linked with foot only by the skin, fascia, caput mediale of gastrocnemius and tibia when all the muscles, intermuscular vessels and fibula were removed.

目的 探索迟发性小腿全长肌间血管全部坏死而导致除腓肠肌内侧头以外小腿肌肉全部坏死，仅以皮肤、筋膜、胫骨连足的情况下肢体保留和功能重建的方法。

Electrophysciological indexes: in the experimental group ,the tardy rate of induced motorius action potential ,recovery rates of the amplitude of compound muscle action potential and twitch tension and tetanic tension of triceps surae muscle ,were significantly higher than in the control group.(4) Compared with the control group ,the triceps surae muscle wet weight was significantly greater in the experimental group.(5) histomorphological indexes: the count of myelinated nerve fibers ,diameter of regenerated axon,thickness of nerve myelin sheath and area of capillary were much more in the experimental group than in the control group.(6) observation of ultrastructure with the transmission election microscope: more abundant organella and maturer myelin sheath lay in the injured peripheral nerve of the experimental group, while not lay in the control group.

分别在术后第2、4、6周时进行各项指标的检测，结果发现：（1）实验组SD大鼠在整个实验过程中，其精神、毛发、体重，运动灵活性等一般情况优于对照组；（2）实验组的坐骨神经功能指数恢复率显著优于对照组，P＜0.01；（3）神经电生理指标：实验组运动神经诱发电位潜伏期的延迟率显著优于对照组，P＜0.05；复合肌肉动作电位振幅的恢复率显著高于对照组，两组比较第2周时P＜0.01，第4、6周时，P＜0.05；小腿三头肌单收缩力和强直收缩力的恢复率实验组显著高于对照组，P＜0.01；（4）小腿三头肌湿重的恢复率，第2、4周时实验组高于对照组，差异非常显著，P＜0.01；第6周时，差异仍显著，P＜0.05；（5）组织形态学指标：有髓神经轴突计数、再生轴突直径的恢复率，毛细血管面积，实验组均显著大于对照组，P＜0.01、P＜0.05、P＜0.001；实验组髓鞘厚度的恢复率也显著高于对照组，第2周时P＜0.01，第4、6周时，P＜0.05；（6）透射电镜超微结构观察：实验组再生轴突中细胞器丰富，髓鞘结构成熟，神经再生情况优于对照组。

Today, in the foreign intelligent artificial leg, the executive mechanism which controls the bent and stretch"s movement of knuckle and the pendular movement of calf is a single air cylinder. In the air cylinder, there is a throttle, the cylinder"s damp can be adjusted by controlling the opening of the throttle valve, when the air cylinders damp changes, the pendular speed of calf will change too.

目前，在国外研制成功的智能人工腿中，控制膝关节屈伸运动及小腿摆动的执行机构是一个单级空压气缸，其内有一个针阀，通过调节针阀的开度可控制气缸阻尼，从而控制小腿摆动的速度。

We compared the effect of the number of weekly repetitions of a static stretching program on the flexibility, hamstring tightness and electromyographic activity of the hamstring and of the triceps surae muscles. Thirty-one healthy subjects with hamstring tightness, defined as the inability to perform total knee extension, and shortened triceps surae, defined by a tibiotarsal angle wider than 90 degrees during trunk flexion, were divided into three groups: G1 performed the stretching exercises once a week; G2, three times a week, and G3, five times a week.

我们比较每周重复静态牵张方案的次数对灵活性、腘绳肌紧张以及腘绳肌与小腿三头肌的肌电灵敏度的影响。31例腘绳肌紧张的健康受试者（腘绳肌紧张为无法进行全膝伸展和小腿三头肌缩短（躯干弯曲时胫附的角度大于90度））被分为3组：G1组，进行每周一次的牵张训练；G2组，进行每周三次的牵张训练；G3组，进行每周五次的牵张训练。

If an overzealous student continues to pull the foot up after his thigh stops externally rotating, or if a student or teacher forces the knee downward, the thighbone and shinbone will act like long levers that apply great force to the knee. Like a pair of long-handled bolt cutters, they will pinch the inner cartilage of the knee between the inner ends of the femur and tibia.

假如学生求表现也不管髋关节是否有充分外旋的能力就拚命练盘腿，或是学生或老师太鸡婆地跑去强压翘起的膝头，大腿和小腿的动作就像是使用膝盖为轴心的长杠杆，这将导致股头及小腿内侧部分的疼痛感。

Methods:Nine patients with contraction of Achilles tendon were treated by Ilizarov retractors.The ankle retractors was assembled before surgery and put around leg and foot during the operation.The center of the hinges of the apparatus was pointed to the joint space firstly.Groups of Kirschner pin were penetrated through legs and another two groups through feet and then fixed with the steel rings of the retractors.

用Ilizarov踝关节牵伸器治疗跟腱挛缩9例，手术时先将预先组装好的踝关节牵伸器套在小腿与足部，牵伸器的铰链式关节对准踝关节的关节间隙，在小腿和足部各穿2组克氏针与牵伸器的钢环固定。

A short leg "boot" cast is used to suspend the lower leg.

用小腿上打短的&靴状&管型来悬吊小腿。

Early or too small to walk on the regular stations, there is going to be bent leg, the doctor said to be x-shaped legs, I guess it should be a big distance between the lower leg, she has a two-year-old, the best solution to see a doctor, and the smaller the better.

走路早或是太小是就经常站，是会引起小腿弯曲的，医生说是x形腿，我估计应该是小腿间距大的，她已经两岁了，最好去找医生解决，而且越小也好的。

Ratio of wet weight of musculus triceps surae in each group: Muscular atrophy gradually recovered with the time increasing.

各组大鼠小腿三头肌湿质量比：所有大鼠手术后术侧小腿三头肌萎缩。

No positive image emerged in muscular tissue and sciatic nerve at 72 hour in Na131I group and saline group by radiography except obscure image in local triceps surae after 6 hours in Na131I group.

在左侧小腿三头肌分别注入131IHRP、Na131I或生理盐水500μl，于注射后6、12、24、48、72小时后处死动物，取左侧带小腿三头肌的坐骨神经全长行放射自显影和坐骨神经HRP组织化学染色。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
