腘绳肌腱取了还会长吗

经常有交叉韧带重建的病友问我取的基建在什么部位，那么我今天就跟大家画一画，那这一部分呢就是边股，那么上面这部分呢是股市投机的基建，下面呢这个是 平整带，然后上面呢，这是我们膝关节的鼓鼓，下面是劲鼓，那么在鼓鼓和劲鼓之间呢，这部分呢就是内侧的半月板，我们把它叫做啊， mediominenice curse， 同样的啊，这个是外侧的鼓鼓，外侧的平台，那么这部分呢就是外侧半圆板。 好，那下面这个这段我们叫禁股啊，我们做诊断的时候取的基建是什么地方呢？就是大概啊指点在这个地方啊，那这两个基建呢，是从膝关节的后内侧啊，大致后内侧过来的，那么这样的两根基建，那么上面这根呢叫古搏基，下面这根呢叫 半件机啊啊，那么这个过程基建取掉之后，对膝关节的功能有没有影响呢？因为这个过程基建呢，他是膝关节后内侧的一个辅助的肌肉，他有一定的膝关节的屈膝和膝关节内旋的功能。 那么严格来说呢，取机电之后，对这两个功能是有一定影响的，但这个影响比较小，因为它是一个辅助机，同时呢蚊香包括这个机电是可以再生的啊，将来再生之后，这个功能是能够恢复的。

这个小哥哥你过去有没有什么印象？韧带他不做，他就是维持一个膝关节稳定性的一个组织，一个结构了。我们一般来说取自己的肌腱，这两根，我们说这叫过神肌腱，具体说来是一根半剑肌，一根骨搏肌，这两根肌腱主要是 起到一个屈膝内旋的一个作用，但是你的韧带断了，我们需要一个工人相似的一些东西来替代他。拆东墙补西墙，老师把这里的拆了放在这里以后有没有什么影响？很多人都这么问，这个人即将来拆东墙补西墙，这肯定东墙 他不是那么重要，但人体他没有废物的东西，只是说拆一个不那么重要的东西来去补一个相对重要的东西。早期可能在屈膝，力量可能会丢失一点，但是 这个屈膝的肌肉啊，除了他俩还有很多少了，他俩不那么重要，这功能虽然丢失了百分之十几、二十几，但是可以通过其他肌肉来代偿。

前叉韧带重建的这种字体的这种肌腱少一半的好消息告诉你，他的肌肉利用率高。同样大小的前叉新韧带，传统手术要切断两根长长的过程肌腱才能做出来。那么全内韧带重建呢？只需要一根就能够抵两根，用专业的打法做出质量一样的新韧带， 而且少割一根大腿上的筋，这样的韧带重建对身体的伤害小，后面恢复也快。我是协和骨科黄医生，膝盖疼，肩膀疼，等待断了来协和找我。

啊，那么这个过程肌腱取掉之后对膝关节的功能有没有影响呢？因为这个过程肌腱呢，他是膝关节后内侧的一个辅助的肌肉，他有一定的膝关节的屈膝和膝关节内旋的功能。那么严格来说呢，取肌腱之后对这两个功能是有一定影响的，但这个影响比较小，因为他是一个辅助肌。

很多叉友关心一个问题，我们取件了这个过程肌肌腱之后，会对我们膝关节产生一定的影响吗？会有一定的影响，取的键是我们大腿后侧半腱半膜使用过程肌的一部分，这条肌肉的功能是屈膝以及有力的内旋作用， 那么这个条肌肉去掉之后呢？肯定我们这个功能会稍微受一点影响。其次整个大腿后侧力量会变弱，那么我们整体的运动表现能力就会下降一部分，但是大家不要去太担心，只要大家很好的去练我们整体膝关节周围的力量，那么还是可以进行一个补足的。

前几天门诊有一位爱好运动的小青年，由于前交叉韧带损伤找到我想要做人工韧带重建，因为呢，他听说人工韧带恢复快，我跟他解释了三种材料的利与弊， 最终呢，他选择了字体双数八股重建。这里简单说一下韧带重建材料的选择，最主要的是字体一体和人工。三种字体的优点呢，就是不容易排异和干扰， 缺点呢，就是要取自体的基建，一般呢，我们取的自体过程基建呢，对身体几乎是没有影响的。一体的优点呢，就是不需要取自己的基建，但是呢，缺点就是费用比较贵，相对排异和感染的几率呢，是高于自体的。那么人工韧带的优点呢，就是恢复比较快，因为人工韧带主要靠机械 坚强的固定，缺点呢，就是没有见骨欲和随着时间推移呢，可能会出现见骨见面的松动，那时候呢，可能就要再次手术了。

检查术后一个月，现在走路没问题，但是总是感觉膝盖的这个胳膊处有这种疼痛感，就像你使劲有抽脂的感觉， 那么我教大家一个方法，然后我是这样来训练，可以坐到凳子上，沙发上，然后脚下垫一个毛巾啊，然后先找找这个，先找找这个 我曾经的发力，我现在目前都可以自己来控制这个肌肉，那么如果你找不着的话，你可以用脚趾来去用脚趾头去用力拨动毛巾，然后往你的脚心方向去拨，这样脚背可以弓弓起来，你就能找到这个 俯卧处，也就是取肌腱地方的这个发力感，然后能让你的肌肉有这种收缩的一个能力。但是做的时候刚才做会有一些疼痛，但是你 连续做一段时间之后，这块肌肉可能就能够激活，然后疼痛感会逐渐的减轻，大家可以试一下，一二三四五六，你可以侧面，然后大家可以看的更清楚一些， 看到没有这块肌肉他是有这种收缩的，但是我现在不拨动毛巾，我能控制这块肌肉的发力，如果找不着，你可以用脚趾头来去拨动毛巾，脚背弓起来，慢慢找这种感觉，因为取件的这块肌肉他会有一些受损，所以说这个肌肉我们必须要锻炼他，去刺激他， 然后疼痛感就会逐渐减轻，这个也是在术后嗯，最难恢复的一个部位吧，但是要坚持练习还是 是没有问题，如果还是很难去找到发力感的话，可以去用这个笔尖的这个理疗仪来，比如调到八的模式，这个力量还是蛮大的，可以先去放松一下， 这样的话你的神经也能感觉到这种区域的肌肉的一个控制感，然后更能容易找到他的发力，我都能控制这个肌肉他的自动发力，然后你在做的时候可以这种感觉， 然后也可以去拖动毛巾，这样可以更明显，对吧？我可以调到激活模式，这种力量是比较大的啊， 你一使劲他的这个就会随着你的节奏来去进行控制。现在是 我没有使劲的去控制他，使这个内调仪再去刺激我的肌肉，如果我主动发力，得到感觉之后我主动发力，他会是这样 还是比较有效果啊，大家可以试一下。

韧带重建的材料哪个最好？大家好，我是刘医生，常常患者朋友问我，韧带重建用什么材料，哪种材料最好，如何去选择？ 主要包括以下几种，从大的方面来讲，应该包括了一体基建、字体基建和人工基建三大类。因为一体基建来讲，本身感染的风险和排异的机会比较多，字体化的效果并不好， 所以目前来讲，一体基建使用的频率越来越低，主要是集中于人工基建和自体的基建两大类之间进行选择。 对于我们患者来讲，他会到网上去查询，了解两种方法的不同，最后来讲还要去询问医生哪种方法更好。目前来讲，人工基建和自体基建重建的手术方式的优劣没有定论，有些人拥护自体基， 从前，有些人拥护人工肌健，我觉得是哪个医生对于哪种手术方式最为熟悉，那就是最好的治疗方式。对于自体肌健来讲，因为是自己的乳汁，不存在排异反应，愈合比较快，但是自体肌健存在一个远期如化的问题， 从而有一部分患者做完手术之后，关节稳定性会比原来要差一些。自体肌健还有一个好处，如果做得好，和自己的组织长得比较好，血运恢复比较快，可以使用一辈子，不需要再一次的进行手术。 人工基建有哪些不利的地方呢？还有哪些好处呢？人工基建它的好处就是做完以后稳定性非常的好，不存在远期变动的问题，做到什么紧张的程度以后程度就是这样，所以它的时间呢，稳定性比较好，而且恢复比较快，一般来讲 不需要特殊的支具保护，他的缺点在于手术难度比较大，因为它本身弹性不是很好，所以在选择植入点的时候特别的重要，不然就会发现他会在伸直的时候或者在曲曲的时候容易紧张或者松弛，尤其是在曲曲的时候 紧张了，伸直的时候反而松弛了，这样我们必须找到一个等长点来使它伸直和屈曲的过程都是保持同样的松紧，这样的话患者的功能才会更好。而且有一点我们并不知道人工基建到底能用多少年， 因为理论上设计人工基建的时间还没有很长，现在也就是三十到四十年的时间，所以到底能不能用一辈子不好说，这个就是人工基建的一些利弊。好了，今天的内容就先讲到这里，我 是中国中医科学院望京医院刘劲松医生，如果您也有骨科的相关问题，不妨把核磁片子发给我看一下，我帮您来解决它。

说过了，我抽完之后的话我就力量感觉比这个戒色差很多。这样你看我往后一弄少了一块，我又萎缩这么多，两条肌腱就是两块肌肉。对，我本来箭策嘛跟他是差不多的时候七公分。嗯，但是我 练的还还行，后来恢复的还好，但是后面一摸就少少了一块。

取自体移植基建做韧带重建有危害吗？一般我会选取半链接国际作为首选的一个移植的材料， 非常方便获取，然后长度往往也足够。取了一只鸡件对人体有影响吗？外面肌肉、骨搏肌周围还有很多很强壮的肌肉，我们所选取的这个其实是其中的一小部分，发挥作用的肌肉是有很多的，取了之后对整体的功能影响都是可以忽略不计的。

today， i'm going to show you how to set up perform and program nor de campturing curls provide you with progressions， regressions and alternatives to help you meet your goals and discuss the latest research first， a quick review of anatomy located on the back of the thigh the hamstrings consist of three muscles the semi member nosis， the semi tendinosis and the long head of the biceps femoris since the three muscles attach from the pelvis to the tibia and fibula of the lower leg， they have two primary actions hip extension and knee flexion there is also a short head of the biceps femorist that only axe to flex the knee nordic hamstring curls which challenge the knee flexion action of the hamstrings are usually performed with the intention of preventing injuries or improving performance such as increasing sprint speed i'll discuss the latest research related to both topics toward the end of this video to set up for nordicamstring curls you only need two things a soft surface to neil on such as a pad pillow or towel and a place to anchor your feet there are a lot of options for inkering your feet none of them are perfect for example using a partner requires another person and that person needs to be strong enough and understand how to hold your legs appropriately plus some people find the pressure uncomfortable many of the demonstrations in this video will be performed on a lap pull down machine which i don't find ideal because it forces my knees closer together than i prefer due to the small size of the seat and if you're at the gym， you're taking up a piece of upper body equipment some other options include a barbell with plates on either side of the weights to ensure that it doesn't roll flat bench with a belt or strap to firmly secure your legs an attachment for a squat rack an adjustable strap that anchors to your door and the bigger more expensive pieces of equipment made specifically for nordic hamstring curls at my normal gem i'll either use the smith machine or the metal stall bars， but the little ingenuity and set up time you can do them almost anywhere to perform the nordicampsuring curl attempt to keep a straight line between your knees hips and shoulders as you slowly lower to the floor or object in front of you you'll then catch yourself with your hands and push back up to the starting position during the exercise you can squeeze your glutes to help maintain the position of your hips and trunk while digging your heels into whatever is holding your legs in place essentially you're imagining bringing your heels toward your butt as you fall forward to regress the exercise or make it easier you can do one of two things one allow your hips to bend it's perfectly acceptable because you still get the benefits of the nordic hamstring curl and you can work on slowly straightening yourself out over time to progress the exercise two decrease the range of motion by placing or stacking objects in front of you to progress the exercise or make it harder you can either one increase the range of motion by removing the objects in front of you if your goal is to do a full repetition starting with a shortened range of motion and increasing it over time by gradually lowering the height of stacked objects in front of you is one of the best options to do so and progression number two is to hold a light weight and increase the weight over time if you want assistance you can place a band around your chest and anchor it to a sturdy object above and behind you i've also seen people use a ball dowel， ab wheel and other objects， but i'm immediately not the biggest fan of these tools because they often significantly reduce the effort that people put forward the exercise is meant to be hard before discussing alternatives to nordic hamstring curls and how to program them into your training routine， i want to briefly touch on the research as it relates to injury prevention and improving performance a systematic review by van diecodal in 2019 concluded that programs that include the nordic hamstring exercise reduce hamstring injuries by up to 51 percent however， a paper published by impelas area at all in 2021 reported that there were some methodological concerns with the systematic review that caused it to likely overestimate the benefits of nordic hamstring curls this was followed by disagreements between these authors and a different set of authors all this to say that nordic hamstring curls have the potential to reduce the risk of hamstring strained injuries， but there is more uncertainty than often stated they still have a strong theoretical basis since they promote improvements an eccentric knee， flexor， strength and muscle phasco length which are known risk factors for hamstring strain injuries think of them as causing the hamstrings to get stronger and longer they also have the potential to improve sprint performance but some uncertainty exist here as well in reality the implementation of nordic hamstring curls should be thought of as complementing a comprehensive training program as opposed to a standalone magic bullet since the hamstrings function to flex the knee and extend the hip a well rounded routine should also incorporate exercises that challenge the hip extension action of the hamstrings from a stretched position here are three options one romanian or stiff legged deadlifts two roman chair hip extension these can be performed double leg， single leg or weighted and three hip extension on the glute hammerase machine which can also be done double leg， single leg or weighted if you want to replace nordicamstring curls build up your strength for them or perform other knee flexion exercises in addition to them options include one the glute hamray's machine these can be performed double leg， body weight or weighted two prone hamstring curls double leg， single leg eccentric only in， which you lift the weight up with two legs and lower back down with one leg， three seated hamstring curls， double leg， single leg or eccentric only and four hamstring sliders double leg， eccentric， double leg， single egg， eccentric and single leg lastly if you intend to play sports or engage in activities that involve high speed running it's necessary to include sprinting into your training routine with regards to programming nor de campturing curls it completely depends on your goals if your only goal is to perform a full repetition you should likely aim for a higher frequency of lower repetitions for example you might do three sets of three to five reps two to three times per week there are a few ways to execute the exercise for this goal though one you could build up your strength， so you're strong enough to lower yourself all the way down before trying to pull yourself back up to as mentioned earlier， you could start with a full repetition through a shortened range of motion and increase that range of motion over time by gradually lowering the height of stacked objects in front of you three combine the two you could do a few repetitions per week of luring yourself down as far as possible， while the rest of the repetitions are done through a full shortened range of motion let's say you're doing three sets of five repetitions three times per week as an example since your strongest when you're freshest the first repetition of each set can be focused on trying to lower all the way down then you could practice lowering down and raising back up with objects placed in front of you as needed based on the research if your goal is to elicit the adaptations that might reduce the risk of hamstring strain injuries you only need to focus on the lowering portion of the exercise known as an eccentric muscle contraction in fact researchers usually make sure that participants can't bring themselves back up here's a common scenario taken from pressland at all in 2018 where participants were observed to have sufficient strength to completely control the movement in the final 10 to 20 degrees of the nordic hamstring exercise they were then required to hold a weight plate ranging from five to 25 kilograms to ensure super maximal exercise intensity was maintained super maximal meaning greater than their one repetition maximum you are stronger eccentrically lowering yourself down than you are concentrically pulling yourself back up and most researchers want the nordic to be too difficult to get back up based on the adaptations created by the super maximal eccentric muscle control attractions a systematic review by cuthbert at all in 2020 and a recent study by behind at all in 2022 informs us that a minimum effective dose is necessary for increasing eccentric neaf lecture strength and muscle phasical length for instance that paper by pressing at all found that four sets of six repetitions two times per week for two weeks followed by two sets of four repetitions one time per week for four weeks was sufficient for eliciting these adaptations you either need to start with a higher volume and taper off or gradually progress volume over a period of six weeks on a side note， i've seen some people argue that nordic hamstring curls should be performed it quickly to better prepare athletes for sprinting， but no research has been conducted to form a reasonable conclusion if you've already accomplished one or both of the goals mentioned， or you don't have any specific goals and you just want to train programming nordic hamstring curls simply needs to fit into the context of the rest of your training routine， i'll use myself as an example， i trained my legs twice per week， i could set up my first leg day on monday， so that i do rear foot elevated split squats romanian deadlifts seated leg extensions prone hamstring curls and standing single leg hill raises on thursday， i could do squats single leg roman chair hip extensions nordic hamstring curls reversed nordics and seated hill raises this is just one example， but there are an infinite number of possibilities in terms of exercise selection sets reps frequency， etc before going out and becoming a pro at nordic hamstring curls create a plan be consistent and set realistic expectations they are difficult and can cause a lot of soreness especially for less trained individuals so you don't need to worry about mastering them overnight thank you so much for

自己基建取材从哪里取呢？今天就跟大家做一个简单的介绍，我们可以看到这里这是两根线代表的两根基建的一个走形， 呃，上面一根肌腱呢，我们叫骨骼肌腱，下面一个肌腱叫半箭肌腱，然后这两个肌腱呢一直往大腿的后上方延伸，然后跟我们的肌肉有一个连续。那我们取材的时候呢，就会 把这两个基建进行一个从直点到建府交界的地方，把它整个取下来。那么这一组基建呢，我们就叫 hamstring tendon。 取这两根基建的话呢，我们口子一般性在这两根基建呢，呃，当中位置 做一个大概两到三公分的切口，然后把皮肤切开以后通通过助手的一个切拉，然后我们从当从他的皮肤下面找到我们 这两个基建，使用专门的取件器进行一个切取。这两个基建取取下来以后呢，我们这基建肯定是没有了，然后跟他相连的这个肌肉呢，他会发生一个回缩，这两块肌肉的功能呃，基本上就丧失了。
