I have a lot of patients who come and see me with neck pain that is radiating down the arm.

This condition is called cervical radiculopathy.

It is usually because of a pinched nerve in the neck, either due to a bone spur or a herniated disc.

There's an excellent surgery for this condition.

This is called anterior cervical discectomy infusion.

Basically, through this surgery, we unpinch the nerve by removing a disc in the neck, and we stabilize that level by fusing it.

And today, I'm going to show you how this surgery is done step by step.

I'm making this video for my patients who want to know more about the surgery, see how it's done.

So I'll take you through it step by step.

And also for patients out there who are dealing with a similar problem

and are debating whether or not they should have the surgery.

So today I'm going to show you the case of a patient who had a pinched nerve between the C6

and the C7 vertebrae in the neck, pinching the C7 nerve.

The C7 nerve comes out of the neck

and goes all the way down into the forearm and the hand and can cause some severe pain, numbness, and tingling.

So without further ado, let's get started.

The first step is to place the patient on the operating room table after they've been intubated and they've received anesthesia.

And we check an x-ray from the side

and we put a marker on the skin and make sure that we know where the C7 vertebrae is.

So we mark the skin. And similarly, we put another probe on the skin to mark where the

c6 level is after we figure out where the c6

and the c7 vertebra are we make a small incision between

those two points we get down deeper on the spine

and very carefully we take a tiny needle

and we put it into the c7 vertebra

and check another rectifier from the side now it's very important to make sure

that you are the correct vertebral level

because of course you don't want to remove the wrong level

disc now after you've confirmed your level you focus all of your attention at the c6

and c7 level so the next step is to create some space between the c6

and the c7 bones and how do you do

that well the first step is to take a small threaded pin

and put it into the c7 vertebra similarly you take a second pin

and you insert it into the c6 vertebra next you slide a distractor over these pins

and apply a very minimal distraction maybe one

or two millimeters to gently open up this disk space this allows you more space to work

and this also allows you to open up the nerve so it is no longer pinched

next using a series of different instruments we remove the degenerated disk between c6

and c7 and and we remove it all the way to the back of the vertebral body.

It's very important to remove all the discs because the nerve lives all the way in the back, right over here at this point.

After you have removed the disc, we use special instruments to unpinch the nerve and remove the bone spurs that are pinching the nerve.

So at this point, the C7 nerve has been freed up on both sides.

Now you're left with an empty space where the disc used to be.

So the question is, what do you do about it?

Well, you have to put a spacer over here, otherwise the two levels are going to collapse.

And you have to put a spacer of the correct size.

So the way we do that is we have a series of spacers, trial spacers, that we put in sequentially, and we see how snug the fit is.

When you finally find the correct fit, that is the size of the spacer that you need to put in there.

So in the case of this patient, we used a 6mm spacer

that gave us a very good snug fit both by tactile feel

and by looking at it from the side by the x-ray

so next we remove the trial

and we select a piece of bone a cadaver bone graft called the allograft

and just gently tamp it into place until

that bone is in the center of the disc space

and at this point you check another x-ray make sure everything

looks good you remove the distraction pins the threaded pins

that you put in earlier

and the next step is to put a plate in the front so that you can stabilize this whole construct.

It's very important to select a plate that's neither too long nor too short.

So you take the plate that you think is going to work, put it in the front of the neck, and put it on top of the vertebrae, and secure it temporarily with a temporary fixation pin.

You check an x-ray, make sure it's of the correct length.

Next, we take a drill and drill into the C7 bone.

Take a small screw and put it through the plate and secure the plate against C7.

We put a second screw into the C7 vertebra.

And similarly, we put two more screws into the C6.

At this point, you fight and tighten all the screws.

Make sure that the whole construct is nice and tight.

You look around to make sure that there's no bleeding.

And after checking everything to make sure it's okay, you close up the incision.

After waking the patient up and reversing anesthesia, the patient will be probably in the hospital either overnight or discharge home the same day, depending on how they're doing.

They're wearing a soft collar

and recovery in general for patients who have an anterior cervical discectomy infusion surgery is very rapid and very successful.

この動画で身につける英語スピーキングスキル

動画で英語学習をするなら、このコンテンツは説明的なスピーチの構成と専門用語の自然な使い方、段階的な説明のリズムを鍛えるのに最適です。医療的な場面での説明を通じて、「手順を明確に伝える」「複雑な内容を分かりやすく話す」といった実用的なスキルが身につきます。IELTS スピーキング対策にも役立つ、論理的な語り口の練習になります。

聞き取りに注意すべき発音のポイント

英語の発音を良くするために、この動画の連結発音とリダクションに注目しましょう。例えば、「anterior cervical discectomy」では「anterior」の「r」が次の「cervical」の「c」に連結し、「anteriorcervical」のように聞こえます。また、「it is」が「it's」に短縮されるほか、「we are」が「we're」になるリダクションも多く見られます。これらの発音パターンを捉えることで、自然な英語のリズムが理解できます。

ネイティブのように話すコツ

shadowspeak（シャドースピーク）の練習には、話者のリズムとストレスを真似ることが重要です。この動画の話者は手順を説明する際、「first step」「next」「after you have removed」などのキーワードを強調し、文の途中で適度なポーズを入れています。例えば、「So without further ado, let's get started.」では「ado」を軽く強調し、「get started」をゆっくり話すことで緊張感を緩和しています。このようなリズムを真似ることで、自然で流暢なスピーキングが可能になります。また、専門用語も正確に発音しながら、全体的なスピードを維持することで、聞き手に分かりやすい話し方が身につきます。

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
