I Got Nerve! (And It’s Pinched)

Those of you who have been enjoying my medical adventures for the past year or so are in for a treat: I’m having back surgery! And I’m going to be sharing the details along this journey with my faithful readers (me and one other person).

I may have mentioned elsewhere in these incoherent ramblings that I have a herniated disc at L5-S1, which is pinching a nerve running down my right leg, causing me large amounts of pain when I’m on my feet for too long (“too long” varying  from 10 minutes upward, depending on circumstances).  The discomfort can be barely bearable; if I know I’m going to be on my feet for a goodly length of time, I bring along a walking stick.

Over the past few months, I’ve had a pair of steroid epidurals, a nerve block, and been prescribed Neurontin, none of which has provided any relief. It appears that the only option left for me is surgery.

I won’t know all of the details for certain until next week, when I have a second meeting with my surgeon. At our first encounter, he examined my MRI and showed me what he suggested: a discectomy (at first I thought he said “vasectomy”, which caused me no small consternation). I told him I’d think it over and give him a call in a week. Only a few days earlier, I’d had a nerve block injection, and I wanted to give that a shot at working.

I hit up the internet for a little research, and found this at About.com:

A discectomy is a surgery done to remove a herniated disc from the spinal canal. When a disc herniation occurs, a fragment of the normal spinal disc is dislodged. This fragment may press against the spinal cord or the nerves that surround the spinal cord. This pressure causes the symptoms that are characteristic of herniated discs

The surgical treatment of a herniated disc is to remove the fragment of spinal disc that is causing the pressure on the nerve. This procedure is called a discectomy. The traditional surgery is called an open discectomy. An open discectomy is a procedure where the surgeon uses a small incision and looks at the actual herniated disc in order to remove the disc and relieve the pressure on the nerve.

How is a discectomy performed?
A discectomy is performed under general anesthesia. The procedure takes about an hour, depending on the extent of the disc herniation, the size of the patient, and other factors. A discectomy is done with the patient lying face down, and the back pointing upwards.

In order to remove the fragment of herniated disc, your surgeon will make an incision over the center of your back. The incision is usually about 3 centimeters in length. Your surgeon then carefully dissects the muscles away from the bone of your spine. Using special instruments, your surgeon removes a small amount of bone and ligament from the back of the spine. This part of the procedure is called a laminotomy.

Once this bone and ligament is removed, your surgeon can see, and protect, the spinal nerves. Once the disc herniation is found, the herniated disc fragment is removed. Depending on the appearance and the condition of the remaining disc, more disc fragments may be removed in hopes of avoiding another fragment of disc from herniating in the future. Once the disc has been cleaned out from the area around the nerves, the incision is closed and a bandage is applied.

What is the recovery from a discectomy?
Patients often awaken from surgery with complete resolution of their leg pain; however, it is not unusual for these symptoms to take several weeks to slowly dissipate. Pain around the incision is common, but usually well controlled with oral pain medications. Patients often spend one night in the hospital, but are usually then discharged the following day. A lumbar corset brace may help with some symptoms of pain, but is not necessary in all cases.

Gentle activities are encouraged after surgery, such as sitting upright and walking. Patients must avoid lifting heavy objects, and should try not to bend or twist the back excessively. Patients should avoid strenuous activity or exercise until cleared by their doctor.

What are the potential complications of a discectomy?
The most common problem of a discectomy is that there is a chance that another fragment of disc will herniate and cause similar symptoms down the road. This is a so-called recurrent disc herniation, and the risk of this occurring is about 10-15%.

Most patients find relief of much, if not all, of their symptoms from a discectomy. However, the success of the procedure is about 85-90%, meaning that 10% of patients who undergo a discectomy will still have persistent symptoms. Patients who have symptoms for long periods of time, or severe neurologic deficits (such as significant weakness) are at higher risk of incomplete recovery.

Other risks of surgery include spinal fluid leaks, bleeding, and infection. All of these can usually be treated, but may require a longer hospitalization or additional surgery.

What is endoscopic microdiscectomy?
Newer techniques may allow your surgeon to perform a procedure called an endoscopic discectomy. In an endoscopic discectomy your surgeon uses special instruments and a camera to remove the herniated disc through very small incisions.

The endoscopic microdiscectomy is a procedure that accomplishes the same goal as a traditional open discectomy, removing the herniated disc, but uses a smaller incision. Instead of actually looking at the herniated disc fragment and removing it, your surgeon uses a small camera to find the fragment and special instruments to remove it. The procedure may not require general anesthesia, and is done through a smaller incision with less tissue dissection. Your surgeon uses x-ray and the camera to “see” where the disc herniation is, and special instruments to remove the fragment.

Endoscopic microdiscectomy is appropriate in some specific situations, but not in all. Many patients are better served with a traditional open discectomy. While the idea of a faster recovery is nice, it is more important that the surgery is properly performed. Therefore, if open discectomy is more appropriate in your situation, then the endoscopic procedure should not be done. Discuss with your doctor if endoscopic microdiscectomy may be appropriate for you.

While this may seem like minor surgery to some (including the doctor who had been treating me), you have to realize that I’ve never had invasive surgery. The only procedures I’ve been in an operating room for were lipotripsies, and those involved pounding my kidney stones with sonic waves, not scalpel blades.

But by the time a week had passed, I found that the nerve block was ineffective, and decided that I didn’t want to spend the rest of my days hobbling about in pain if I didn’t have to. When the surgeon’s office called to follow-up with me (I know I said I’d call him in a week, but couldn’t bring myself to pick up the phone and say,”Please stick something sharp into my spine.”), I made an appointment to talk things over with him.

That’s next Tuesday.

I’ll let you know how it goes.

New iTunes Helps Jam More Music Onto Your iPod

I own a 32 GB iTouch, and my iTunes library is my main source of music entertainment around my house, in my car, and even (through headphones, of course) at the grocery store (hey, it beats listening to some marketing researcher’s mixtape and a scraggle of screaming kids; I just have to start remembering that when I sing along with what I’m hearing, people stare).

As an aside, my main source of music entertainment at work is a stack of CDs on which I’ve burned mp3s of every song I’ve liked from 1956-2000 (“All killer, no filler”) and a few GBs of music from Disney parks and movies.

But that’s not why I’ve called you all here today.

One problem I have with my music machine is that it tends to repeat songs. Even with more than 4000 songs onboard, you’d think I’d go for days on “Shuffle” without hearing the same song twice. If I wanted that, I’d go back to listening to regular radio. Well, maybe not, unless I could find a station without Morning Zoos and “Such and Such in the Morning” and Afternoon Drivetimes filled with dj’s who find themselves hilarious as they make humiliating prank calls and host vapid contests between playing songlists manufactured by some research company in the midwest. /rant

Another is that there’s so much music I want to listen to. I have varied tastes; my library includes the Beatles, Jack Johnson, Frank Zappa, Brahms, several different soundtracks from Les Miserables, French chansons, Richard Thompson, zydeco, various collections of world music…you get the idea. And I have several gigs of tunes on an external hard drive that I want to check out: albums that have gotten good reviews, other CDs from my collection that I’ve ripped, others I’ve downloaded.

Basically what I do is sit down every evening and delete the songs I’ve listened to during the day, then every so often load up my Touch with new music. Silly, maybe, but it’s what I do.

So I was interested to read in Chris Pilillo’s Lockergnome newsletter yesterday about a new feature in Tuesday’s iTunes update to version

After the update, when you sync your Apple iPod of choice, you’ll notice a new option on the product tab: “Convert higher bit rate songs to 128 kbps AAC”. Check the box to convert the songs on your device during the sync (the original files in your iTunes library will not be changed).

It takes a while for the conversion; mine took over 10 hours for 2958 files.

When I started the sync, I had about 5.3 GB free on my Touch. When the conversion was done, I had 13.60 GB free for more songs. Quite a difference!

If you have an abundance of songs but a paucity of free space on your Apple device, this is your answer.
