In reply to Removed Userysingo:
Here's some more info regarding my ankle fusion.
The tibiotalar joint gives you most of the up/down movement in your foot, fusion removes all of the movement in this joint, however the subtalur joint which gives you the side to side movement (such as when contouring across a slope) also has a bit of up/down movement so I still have about 20% of the up/down motion in my fused ankle.
For normal activities this is actually enough so I walk with no noticeable limp most of the time, only if I've walked several miles do I start to limp a bit. Running is a different matter, I can still run a short distance to save my life (!) but I can't sensibly do any sport that involves running. Driving is also fine but I do sit a little nearer to the wheel than I used to and have to lift my thigh a bit when using the accelerator like you do when braking.
The operation has a long recovery period. You will be about 2 months total non weight bearing in a cast which makes life quite awkward, especially if you live on your own. Using public transport is effectively impossible so you are entirely dependant on lifts to get anywhere. Cooking and carrying things is very difficult, I got a knee high stool to rest my bad leg on so I could make food without leaning on my crutches and had to eat it in the kitchen as it's impossible to carry it.
You will have a lot of time to kill so try and plan useful things to do. A lot of people said they thought they could have got quite depressed spending so long housebound. It didn't really bother me at the time but once I was able to drive again (after about 4 months) and get out and about a bit I felt an incredible sense of freedom.
During the non weight bearing period blood circulation is affected in the lower leg. Normally muscles are constantly squeezing the blood vessels but they don't do this so well when non weight bearing so when you stand up blood "pools up" in your foot and it becomes quite painful so you need to spend most of the time sitting down with your leg elevated.
After 2 months you can begin partial weight bearing, still with 2 crutches but gradually increasing the load you can bear and reducing your dependance on crutches so that after 3 months you can probably get around the house with only 1 crutch and walk short distances, say across the room, with none.
After 3 months I had my cast removed and initially took a step backover in my mobility until the leg strengthened more, after 4 months I was able to drive, could walk around the house without crutches and walk short distances outside, say a few hundred yards, with only one crutch.
The next 2 months are just a gradual reduction in the need for crutches and an increase in leg strength until after 6 months you should be about back to normal.
When I began weight bearing a physio I was referred to told me to take painkillers if necessary so I did take ibuprofen for a while. What the idiot didn't tell me was that non steroidal anti inflammatories such as ibuprofen, are known to inhibit bone growth. I only found this out when they discovered after 6 months that the joint hadn't fused properly.
Don't make this mistake. Failed fusions (I only had about 30% fusion) normally only occur in the "usual suspects", smokers, people with poor circulation for other medical reasons, the elderly etc.
I've said about my current activity abilities in my previous post. Fusion has removed most of my pain and greatly increased my mobility. It has made no noticeable difference to my climbing ability and I regularly climb ladders for work so getting on and off ships shouldn't be a problem in the long run.
If he could be sidelined to an entirely desk based job, sit with his leg elevated, and can get a lift from door to door, he could probably return to work after a few weeks. If he needs to drive and walk around a bit it could be 4 months and it will probably be 6 months before he can climb on and off ships.
Depending on your employer's sick pay rules this could raise financial issues which he may need to consider. I'm self employed and have no sick pay so had to massively reign in my spending and dip deeply into my pension savings, especially as I couldn't work for a year because of the failed fusion. Luckily I did have the savings to fall back on.
The timings I've given are what I experienced and were in line with what I was told pre-op. I have read online that recovery can be a bit quicker but I suppose it must vary depending on the individual's condition or the surgical technique used perhaps? Either way, its not quick.
Best of luck to your mate and hope the info is of use.
