take yesterdays tibialis posterior dialogue……. translate that to the resultant foot structure that can occur when there is complete insufficiency in that muscle (a valgus heel, midfoot collapse and an abducted forefoot) and then understand that this resultant foot will have a first ray complex insufficiency whereby 1st metatarsal head anchoring will be compromised. Now watch todays video by Dr. Waerlop and put the two together. Yes, tib posterior insufficiency can be a cause of bunion-hallux valgus formation.
1 + 1 = 2
not only are we foot geeks, but as you can see we missed our calling in mathematics as well !
