New Ground – Part Two

(Scroll down for New Ground – Part One; beginning of full narrative starts with Finding my Feet)

On the morning of the second day in the rehabilitation hospital, Dr Ellis came by with what looked like a pair of household pliers. Without fuss or ceremony he began pulling out the thin metal pins that were holding my eight toes in a straightened position. I had been dreading this part, but it was over too quickly for me to register much fear. It was more ridiculous than painful to watch Dr Ellis work up sweat as he applied simple DIY techniques to my toes. A few simple plasters later, and there was no more metal in my toes, apart from that embedded permanently in the top joint of my big toes.

Right before the pins in my toes were removed

For my exercises on Day Two I graduated to sitting in a chair, practising lifting my foot by my tendon against the force of gravity. This was definitely a more challenging exercise than from a prone position in bed. But I was getting better at creating the mental pathway between my ‘request’ to my foot and the corresponding action. I no longer had to tap my foot with my finger to help my brain know what action I required of my tendon. I found that meditation and visualisation helped to make this new connection happen faster. As research in neuroscience shows, the brain is quite adept at finding new neural pathways – and my brain seemed to be picking up the new pathway fairly quickly.

Pins removed and simple plasters put on.

On Day three, I was finally allowed to give me feet a good soak in water and salt so that the ‘elephant skin’, as I unlovingly called it, could be scrubbed off. I felt more prepared to have a good look at my feet than I had been on the first day. They still weren’t pretty, but the scars were fairly thin and neat. My feet were a little bit swollen but they were definitely shaped like normal feet:  quite nice feet actually.

A poor mobile photo – with my ‘pet’ koala in the foreground – but it does show a scrubbed and much improved looking left foot!

Once thoroughly dried, I got to put runners on my feet for the first time and put my full weight on my feet. How incredibly strange! It felt like I was going to fall forward. I had not been conscious of the fact that for years I had held myself up on the backs of my heels, barely using the balls of my feet, toes or calves to hold myself upright. It was also drawn to my attention – by my astute and eagle-eyed physiotherapist, Sylvia – that I was continuously bending my knees rather than standing straight. I had not realised that I kept a bend in my knees to retain my balance. Now that I was practising my foot motion from an upright position, I had to re-learn standing!  My inner thigh muscles were weak as I had been using my outer thigh muscles, walking as I had on the outsides of my feet to compensate for my high arches. But where I once in regular fear of going over on my ankles, they now felt as if it would be quite difficult for them to go over. And it felt incredible to feel so much more of the floor under my feet. I was literally more grounded to the earth!

There was to be no real walking for me yet. First it was ‘baby’ marching, practicing the foot lift motion as the first thing I did in a step. Again, this was new learning for me and my whole body. For years, largely unconsciously, I have begun my steps by swinging my leg out to achieve forward momentum; on my left side especially, my weak tendon did not have the strength to pull my foot up. That is why people often assumed the issue was in my hip or leg.  Even though my small exercises did not look like much, and even though I was a far cry from my original expectations, it was exciting to have a strong set of tendons that were doing the job they were supposed to. And they were doing it well!

It wasn’t until the second week of rehab that I started the experiment of walking. Bear in mind, I was still making full use of my crutches. My balance was weak and I couldn’t imagine letting them go. But my various physiotherapists – all of whom had been educated in CMT and the re-training process by Drs Ellis and Warren – also insisted that I use the crutches to promote the correct gait. And re-training meant that I was taking very small steps. With every step, I was practicing pulling up my foot and holding it up until it came back down to earth. But I also had to remember to straighten my legs which were nervous about this new walking style and inclined to bend. Walking in my previous life was always fraught with the real risk of tripping or losing my balance – so my knees were use to being ready! The process was more mentally than physically exhausting. As Sylvia noted, the ultimate goal was to ‘forget’ about walking!

As I neared the end of my stay in Hirondelle, it became clear that my original image of walking out of the doors like a normal person was out of line with the reality. One person had excitedly told me I would be “dancing” when next I saw her. I was still a far cry from dancing and was continuing to reconcile emotionally with the journey ahead of me. I was now walking, and without either crutch for short periods, but it was rather slow going and tentative.

However, I had gained huge ground from the moment when the casts were loosed from my feet, two weeks earlier. I was being released into the big world of obstacles and uneven ground with my new feet to take me forward. There was still much work to do, but it was now largely up to me to carry on the challenging task of re-educating my tendons, feet, legs, muscles and brain. After all, we all start in this world with baby steps.

The “Nitty Gritty”

The pain in my feet did increase a bit following that first night post-surgery as the spinal morphine wore off. But my pain never increased beyond a 4 or 5 out of 10. It was never unmanageable and I never once made use of my morphine drip, which was perversely disappointing. I do believe my excitement for the final outcome mitigated some of the pain.

On Day 4, as my last tube was removed (the catheter), I was feeling little discomfort relative to the major reconstruction that had been meted upon my feet. My original white plasters, with splits at the back to allow for the swelling, were now fully encased in two strikingly purple casts. They looked almost stylish, if you can call flamboyantly coloured Ugg Boots stylish.

Me, my koala Joey, and my purple feet.

But they were in fact functional, as evidenced by the couple of short trips around my hospital room with the aid of a walker.  But my first few steps were a bit shocking as I felt pain radiating through the tops – not bottoms – of my feet. And the weight of the casts definitely made things slow-going and awkward initially. But, it was an amazing feat (ha ha) that I was applying weight to my feet less than 72 hours after the operation.

Dr Ellis and Dr Warren are unique in their approach to getting both feet ‘done’ simultaneously.  In my case, each of them operated on a foot in concert in order to lessen my time on the operating table, which was still almost six hours. Their 15 years of experience in this procedure also shows that allowing the patient to go through the motion of walking as soon as possible begins the process of re-training the brain’s relationship with the correct motion of the feet.

This approach has made it more feasible to request the time off work – 9 weeks in total, including two weeks of rehabilitation. It’s also far less expensive – for me and my employer. As I understand it, surgeons in North America tend to operate on one foot, allow time for the recovery process, and then operate on the second foot. But the other benefit to Drs Ellis and Warrens’ method is that the feet have the opportunity to re-learn the process of walking in unison, thus promoting a balanced gait in recovery.

On Day 5, during his daily visit, Craig noticed with excitement that I was walking heel-ball-toe – the full range of motion – in my chunky casts. Amazing! I hadn’t even noticed, so pleased was I that the pain was greatly reduced from the day before and I was not cruising (slowly) down the hospital hallways on crutches. What I had noticed was that I was now able to pull my foot up to begin the motion of a step, even with the weight of the casts.

One of the symptoms of Charcot-Marie-Tooth disease (CMT) is what’s referred to as Drop Foot – the loss of muscle function or generalized nerve weakness in the front of the lower leg (http://www.footeducation.com/posterior-tibial-tendon-transfer-to-dorsal-foot). Before my own diagnosis of CMT by Dr Garth Nicholson, Professor at Sydney Medical School and a peer of Drs Warren and Ellis, I had no idea this was the reason my feet would fatigue quickly and why I could scarcely lift my feet in heavy shoes. I had just assumed it was related to the actual structure of my feet. Dr Nicholson was in fact the first to map the CMT gene, such that the disease can now be confirmed by genetic testing in a matter of weeks.

The reason I was now able to lift my feet at their bases was due to the transfer of tendons, one of the arsenal of procedures performed during my surgery. Dr Ellis told me upon our first meeting that he and Dr Warren were pioneers of incorporating tendon transfer in concert with the correction of high arches (aka pes cavus). Most orthopaedic surgeons fuse the ankle bone to increase the stability of the foot. Whilst this addresses the issue of stability superficially, it also lessens mobility. By combining the re-structure of the foot with the transfer of the strong tendons underneath the foot to the top of the foot, I have had both problems addressed in one operation.

But it doesn’t end there. Along with the reduction of my arches and straightening of my heels by osteotomies (the removal of a chunk of bone from one part of my foot and moving to another) and the transfer of tendons, I have also had all 8 small toes straightened with wires and the big toes straightened with metal bolts. Eight procedures in all  – multiplied by two feet. No wonder the operation took over six hours!

As I write this posting I am fast approaching the four-week mark since my surgery. I have been happily – and easily – walking on my booted feet for just over three weeks now. I have the unforeseen benefit of living in a single-storey house. The house does have a very long halfway that I have been required to walk up and down daily, but I have noticed incremental improvements in my ability to navigate the distance. I’m now often on a single crutch – or walking without either when I have ample countertops for balance. I also have made two relatively short trips out of the house. But otherwise, I have been enjoying the opportunity to put my feet up (literally) and do very little.

In just over two weeks’ time I will have my purple ‘Uggs’ removed and I will then begin the intensive two-week rehabilitation process as an in-patient, strengthening my new tendons and feet as I learn to walk anew. Not long to go now…
