I had open surgery, blood vessels and outer tissue lifted and one mesh stitched to the Abd wall. Vessels and tissue laid back, and a second mesh stitched over. Upper internal stiches, and then skin staples.

In both cases, one has to avoid lifting weights, or strenuous exercise.

I only know of two op failures, both with keyhole method. (Both where the people went back to work too early)

So are you advising this person to go or to cancel?

Neither, I am advising caution. Years after my op, big skiing days stress the internal. I only knocked back a 13 week gap to a 12 week.

I bet that feels better

It does, Tony, only 5 sleeps, then heaps of sleeps in N. Which will be good, if my knee recovers from Cairngorm.

Buy shares in Ibruprofen, now.

1. Well done to TonyH for managing to address a story about Boots, and still managing to squeeze in a reference to Niederau.
2.Rear entry boots are for peope doing it the right way! -)

Pablo, you know how to wound. -)

Well spotted folks, cold boots appears to be the problem.

Pablo, a member of our family bought a pair of Nordica rear entries just last year, in Saas Fee. It appears that the manufacturer's production plan for these boots, is based on batch size of 5000 boots ~ and they keep getting sufficient orders.

Not only that, but the shop supplied replacement heel and toe bases for my OH's Nordica ~ 20 years old! What service! Having said that, she has regretted not just buying another pair, while she was there.

Can't find a replacement for my Reichle though. Both you and Bandit supplied me with a web site, but on neither occasion was I able to source through to Reichle.

I just love mine to bits. Easy to get on, ONE CLIP PER BOOT,so I'm usually half way up the T bar before Mel has got his first boot on. Dead comfy, like slippers. And ~ most important, for my dodgy knee ~ when it comes to taking the boot off, the rear opens up wide, and I am not wrenching the knee to get the foot out.

It will be very easy for the internal mesh to fail. It was explained to me that a keyhole is just a single mesh stitched to the abdoment wall.

Didn't think it was that obscure, Trencher! Gave my engineer's mathematical answer!!

Funny, you should mention the bootflex, mine probably predate the unit of flex, but when I was unloading my gear tonight, I noticed that the support at the rear top of the liner, has split vertically on one boot. Hence One boot is very flexible.

I'm looking for a meccano solution, I think. :wink:

Peterk11, I disagree with many of the respondents. Ski lengths are not just related to height as one or two people have indicated.

When you initiate a turn you are transferring momentum. The force on the ski is a function of weight x the square of the velocity. Hence, the biggest element is your speed.

You aluded, in your initial posts, to being able to "manage" red runs. My reading of that is that you will be doing about half of the speed of one poster, and about a third of the speed of another, both of whom I have skied with. It doesn't matter if I am exactly right.

So, if either of these aforesaid skiers are about 12 stone, then the force imparted to your skis will be about one sixth of the force imparted to their skis.
