Hereditary sensory and autonomic neuropathy type IV (HSAN) is a rare and debilitating disorder highlighted by congenital absence of pain and anhidrosis. Orthopedic sequelae include physeal fractures, Charcot joint development, excessive joint laxity, soft tissue infections and recurrent painless dislocations, all of which often present in a delayed fashion. While there is no accepted guideline on management of these patients, several case studies have highlighted the importance of early diagnosis and cautioned against surgical intervention in these patients due to their inability to perceive pain and comply with post-operative restriction. The purpose of this case report is to present the clinical course of a patient with HSAN IV and the unique orthopedic challenges it presented. While some of her orthopedic injuries healed appropriately following treatment, others have gone on to have devastating complications and progressive joint destruction. Level of Evidence: IV.
