Surgery

I have long been trying to muster the energy to recap the details of the surgery. I should clarify--the details of the surgery according to me. Keep in mind that I have no medical background and I have been the stressed parent listening to the doctors, so if I say something wrong, I'm sorry. I will do my best. Also, you may want to pass on this post if you get squeamish! I will tell you what I know about Steven's rotationplasty.

Before the surgery, we met with the surgeon to clear up any concerns and also so that he could measure all of us. He needed to estimate how tall Steven will be, and how long his femur will eventually be. He figured out how many inches taller than average Rob and I are, then he averaged that number. I believe he did the same with our femur length. He told us that 2/3 of the growth of leg comes from the two growth plates that Steven would be losing, and 1/3 comes from the top of the femur and bottom of the tibia combined. That had to do with the calculations as well. I'm not even sure what the final number was, but whatever it was, he is counting from the center of motion of the ankle, so it looks farther out than it functionally is.

That morning, we went to the hospital and the doctor came and signed the leg with the tumor. His surgeon would be the main one working, but he would have an orthopedic fellow and a resident assisting him. Steven didn't seem terribly worried. The nurses offered him some kind of relaxant like Atavan, but he said he didn't need anything. He had his electronic stress control, the iPad to keep him company. We walked down to the hall to take him to the OR. The anesthesiologist had to remind me to give him a hug. Yes, I am that good of a mom. :) Steven was talking to the anesthesiologist up until he went to sleep.

I think that my biggest fear during the whole surgery was whether or not he was operating on the correct leg. It was one of those "did I turn the iron off" kind of obsessive/compulsive worries. I even made Rob ask the nurse during the surgery if he was operating on the right leg. The nurse would call us every 2 hours or so with updates. The doctor had strongly recommended that we not stay at the hospital all day. I thought I would be able to for at least most of the day, but it turned out that I could hardly stay there at all. I wish I could say we did something amazing during that time. I went home and showered, exercised, straighted up, packed. Rob stood vigil. I came back and we went out to lunch with Rob's dad. I talked on the phone a little. He played with the iPad. Later, I went shopping with my sister and he went to get a CD player installed in our van. We then went out to dinner with my parents. I was shocked that I was able to eat that day. I was mostly pretty calm all day. After dinner that changed. My dad stayed to wait with us. We were the last people in the waiting room and around 6:15, the nurse told me that they were just finishing up and the doctor would be in shortly. I believe it was more like 7:45 when he came in. By then I was ready to crawl out of my skin.

What a relief when we finally heard him coming into the room! His big smile melted away my anxiety. He said, "It couldn't have gone any better," and that Steven would recover in the ICU. I will try to describe what I know about the surgery, but like I said, I may be wrong.

Most of the time of the surgery was spent dissecting out the veins and nerves. These were kept intact, not cut. There was some question with one of the nerves whether it would survive because it was so close to the cancer. Luckily, there was a 2cm margin and the surgeon was able to save it. When the nurse called me at 3:30, she said they were still in this phase of the surgery but that they were getting close to finishing that. The nerves are very small and it is a very meticulous work.

Once this was done, they could cut out the bone. I am thinking that the dissecting included taking out the muscle surrounding the bone, but I guess no one ever told me. The bone was cut just about the knee, and then wherever they calculated they needed to cut on the tibia to make the limb the proper length. Once the bone was taken out, they rotated the foot. He bored holes in the femur to fit the tibia and the fibula. He used a metal plate and 5 screws to secure the bones together. Those will be there for life. I'm not exactly sure the order of the next things, but the muscles were sewn together with non-dissolvable sutures. The slack in the veins and nerves were kind of bundled in a switchback sort of pattern. They used a flap of muscle from his calf to cover up this "bundle" of nerves and veins. For a while, there will be a bulge on his leg from this, but it will eventually atrophy and smooth out. I have not seen the leg under the bandages, but the doctor tells us that there is only one incision that circumscribes the leg in a circle. The soft tissues are stitched with dissolvable sutures.




This morning when the doctor looked at Steven's leg, he decided that the swelling had subsided enough to cast it. At first, it was just very bandaged up. As far as the cancer goes, he said that the tumor seemed hard, which is good, but other than that he cannot tell how it responded to the chemotherapy. He took it to pathology who will use a band saw to make about 20 cross sections. They will then decalcify the specimens and examine them carefully to see what percentage of the cancer cells have died. If there is 90% necrosis (cell death) or more, it will be considered a good response. He will then have 20 more weeks of the same chemotherapy regimin that he has already been on. If there is less than 90% necrosis, Steven will need to do 30 more weeks of chemo, and they will add two new kinds of chemo onto the schedule.

So, there is my best attempt to explain. Please let me know if you have specific questions and I can see if I know the answer. I am literally amazed that this is even possible. I'm thankful to the surgeon--he is my hero. I am thrilled that the cancer is gone. Rob said it was hard for him to first look at Steven in the ICU, but it didn't take long for him to become accustomed to his new leg. I don't know why it wasn't hard for me. Maybe because I have watched every rotationplasty video on Youtube four times and I've poured over Google image rotationplasty images. Or maybe it is unconditional mother love or God giving me strength.



I am so happy to have Steven home with us now! It just makes life so much easier to have the family together instead of scattered throughout the valley. Steven is doing really well--he is crutching himself to the bathroom and really is acting like himself again. (He tends to get kind of agitated when he is in pain.) He will have an appointment in a week an a half where the surgeon will decide if he has healed up enough to start chemotherapy again.

Portacath

Perhaps this is TMI, but I've had so many people ask me about Steven's port that I thought I'd put a picture up to satisfy the curiosity out there.



This is the way he gets his chemotherapy and all his blood draws. At the same time he was anesthetized for his biopsy, a surgeon placed it under his skin threaded the catheter into his artery. Before he ever gets poked, we put a cream on his skin at the port site to numb it, so as long as I remember to apply it, he doesn't feel anything. The cream needs to sit for about 30 minutes, and I admit that at first I was terrible about remembering so the home health nurse would show up and poke him without the port site being numb. He was a tough cookie and didn't complain, but once I remembered it and he decided it was so much nicer so now he faithfully reminds me about the cream.



In other news, he made counts today and so we are off to the hospital tomorrow afternoon for methotrexate. His red blood cell count was quite low, so they will check it again tomorrow and he will likely get a blood transfusion to bring the counts up. I never would have suspected it, though, he's been acting just fine. He did have a bit of a headache tonight.

If we get lucky, he'll get to come home Easter morning. I'm trying not to get my hopes up, but cross your fingers anyway!

Rotationplasty

Cancer has brought all kinds of new decisions to our family. Little ones like, 'how much TV should a sick kid (or his well siblings) be allowed to watch' or 'should we get a dog?' Big ones like 'should we buy a house and/or a different car?' We are facing probably the biggest decision of all right now--'what kind of surgery should Steven have in order to re-sect the tumor?'

Cutting the tumor out is vital--without that his chance of survival plummets. The tumor is about the size of a tennis ball and it is in the top of his tibia, over the growth plate. The entire top of the tibia must be removed. There must be a wide enough margin to make sure all of the cancer is gone.

In the U.S., most patients with a tumor near their knee will choose to have limb salvage surgery by replacing the damaged bone with a metal prosthesis. It would be placed inside their leg, attached to the healthy bone. This is called an endoprosthesis. This is similar to a total knee replacement, but different because it involves replacing even more of the bone. The advantage of this surgery is that the leg looks normal. A couple of the disadvantages are that activity is limited in order to preserve the joint and there are often complications that arise from infection.

The limb salvage procedure becomes more complicated the younger the patient. The metal bone needs to be small enough to fit in his leg, but large enough that it can support a grown teenager. (The endoprosthetic usually needs to be replaced when the child is full-grown.) If it becomes infected and can't be controlled by antibiotics, then the leg would be amputated.

Another major obstacle in Steven's case is the location of the tumor. Because it is on his tibia, it makes the limb salvage more complicated and increases the chances that it will fail. If it were to succeed, he would end up with a weak leg because they would use some of his calf muscle on the front of the leg. The doctor thinks that in Steven's case, the chances of a successful limb salvage are between 25-50%.

And so, after a lot of research and prayer, we have decided on a form of amputation called "rotationplasty." It is hard to explain, so watch one or both of these videos and you will see what I am talking about:





You can see why we don't make this decision lightly. Although Steven isn't particulaly athletic, he is an average, active boy. Running and jumping are just part of the program. And who knows what he will be like 10 years from now? With a rotationplasty, he will have more choices.

And what does Steven think? He is sure that rotationplasty is the right choice. He made his decision based mainly on the conversations we've had with his surgeon. He says he doesn't care what people will think of him. I asked him why he wants to have rotationplasty and he said, "Well, first of all I will be able to do more things with the rotationplasty, and also I hate the hospital and don't want to have any more surgeries than I have to, and also because it is what the doctor recommends."

And so there you have it. The surgery isn't scheduled yet, but it should happen at the beginning of May if all goes well. He'll be in a cast for 6 weeks and then should be walking withing 3 to 6 months and hopefully back to normal activity within a year. As weird as it looks, it really is amazing that this is even possible. It is functionally preferred over a normal amputation because you have your own joint and a longer leg to operate the prosthesis. Also, the nerves are connected so you don't get the phantom nerve sensations associated with amputations.

The price of rotationplasty is that it looks strange. At best people will stare at him, at worst they will bully him. It will not be easy. He will have to relearn how to walk and then find the courage to be different. I hope he will push himself to new heights and find a strong sense of self as he overcomes this very difficult obstacle.

But any of these surgical options come at a price. And it is a price we are willing to pay to preserve his life.
