Plantar Fibromatosis

Plantar Fibromatosis Facts:
  • Synon - Ledderhose Disease, Fibromatosis Plantans
  • Similar to Dupuyten's contracture but involves the plantar regions.
  • May be associated with joint motion contractures, esp the big toe.
  • Treatment is similar to that with Dupuytren's contracture, ie surgical excision is the best option.
