Q

Pathogenesis of hallux valgus?

A
  • Lateral angulation of great toe
  • Tendons pull realigned to lateral to central of rotation of toe, worsening deformity
  • Vicious cycle of inc. pull = inc. deformity
  • Sesamoid bones sublux =less weight through big toe
  • As deformity progresses deformity of lesser toes occur
