Q

How do we manage Hallux Rigidus?

A

Non-operative:

  • Activity modification
  • Shoe wear modification
  • Analgesia

Operative

  • Cheilectomy (removing the dorsal impingement)
  • Arthrodesis (1st MTPJ fusion is gold standard but permanent)
  • Arthroplasty (1st MTPJ hemiarthroplasty is good for maintaining ROM but fails a lot)
