1. HALLUX VALGUS Moderator 2. How do I approach the problem of recurrent hallux valgus? 3. How do I approach malunion of a metatarsal osteotomy? There is no motion of

the hallux and overload of the 2nd metatarsal. 4. When do I do a modified Lapidus procedure and when the Original Lapidus? 5. What do I do for a failed hallux MP implant arthroplasty? 6. Her toe sticks up in the air. What is it about this Weil osteotomy? 7. This 2nd toe MP joint seems a little subluxated. Can I repair the plate or should I

just stiffen up the toe with a k-wire? 8. How do I decide between a k-wire or some expensive device to fix the toe? 9. THE MIDFOOT Moderator 10. Someone missed this Lisfranc injury which is now 6 weeks out. Can I still fix it or

should I go straight to fusion? 11. The navicular fracture seemed easy, now I have a non-union and a malunion.

What now? 12. Taking out the tarsal coalition was easy, but now the foot is even flatter. What

now? 13. My technique for lateral column lengthening. 14. THE ACHILLES AND OTHER TENDON PROBLEMS Moderator 15. I thought that putting the dislocated peroneals back was easy but now she is

back with recurring dislocation. What now? 16. Is it worthwhile trying to fix a chronic rupture of the FHL? 17. Malunion of a calcaneus fracture? I thought that all that ever happened was a

little arthritis. 18. How I correct a varusmalunion after a triple arthrodesis. 19. ANKLE INJURY Moderator 20. I have been telling everyone to use these sutures to hold the syndesmosis, but

there is recurrent diastasis and he wants to play football. What now? 21. This arthroscopic ankle fusion was supposed to be straightforward, but the foot

and ankle are still a little crooked. How do I correct this malunion? 22. My favourite technique tip for bailing me out in the ankle.

13

23. How do I approach the correction of the patient with a failed Brostrum procedure?

24. I over corrected the 1st metatarsal osteotomy. How am I going to bail on this one?

25. My favourite cavus foot technique tip. 26. I should have listened to my own advice. Do not replace avarus ankle deformity. 27. Now that the prosthesis has subsided and buried itself into the calcaneus, should

I fuse it or try another replacement? Perhaps I can use a custom prosthesis. 28. How do I assess the ankle for instability when I am doing ankle replacement. If it

is unstable, how do I fix it? Canadian Orthopedic Foot & Ankle Society Foot & Ankle Symposium, Jan 29 - 31, 2015
