Hallux Valgus Correction
Post Operative Instructions


  • Lapidus: You will have a plaster cast on your ankle and foot for 2 weeks following surgery
    • – At 2 weeks you will be placed in an aircast

  • The surgical incision has been closed with sutures
    • *IF a pin has been placed, this will be removed at your 4 weeks appointment
  • Do not get the cast or wound wet for the first two weeks. When showering place a bag over the cast and secure with tape to your leg to avoid the cast and wound getting wet
  • Do not remove the dressing until your 2 week appointment – the first dressing change will occur at your 2 week appointment
  • Stitches will be removed at your 2 week appointment
