I had my Canon 500 MKII lens attached to my 1D4 plus a 1.4x converter when one leg on my tripod just started to collapse, I raced ( well as fast as a 61 yr old can race) across to grab it, slipped on my tiled kitchen floor resulting in hurting my elbow, my right ankle and a swollen right 'unmentionable' round object as this is where the camera hit me, but happy to say no damage to any of my kit- only to me!! I have now binned the tripod and am sourcing a new one- a Gitzo GT4542LS looks favourite. I am now laid up for a couple of weeks.
Ah man! Hope you feel better soon. Glad the gear didn't get damaged.
