In reply to kit perry: I broke my femur, medial malleolus and fibula just over a year ago - the screws in the malleolus caused no end of problems with the head breaking through the skin any time I knocked my ankle jamming/scrambling along the bottom of crags etc.
I was booked in to have them out along with the fibula plate but managed to re-fracture the fibula 6 months after the original injury and just before the scheduled op, in a minor slip on some wet grass, which would have been nothing other than a bit embarrassing had the metalwork not been in there. (The surgeon explained that plate creates a stress riser which deosn't allow the bone to flex, so when I slipped it snapped over the top of the plate where normally the bone would probably have flexed a bit and absorbed the impact.) I had a longer plate put in for the fibula and the malleolus screws removed at the same time.
The malleolus is now much, much more comfortable and even though the fibula plate doesn't cause too many problems, I'm still going to tell the doc's it is and have it removed for fear of re-fracturing again (not unlikely considering what we do as climbers). The metalwork in my hip from the femur break can get pretty sore after long mountain days, but I that's a major op and unlikely to be a mechanism for further injury so I can live with it. To me it's about levels of risk vs potential benefit and lower leg ops (from my admittedly limited experiance) seem to be fairly low risk for potentially large gain and the rehab doesn't take too long so it's worth it in my view. My 2p anyway - sorry for the essay! Cheers, Rob
