"A Lisfranc amputation involves the disarticulation of all five metatarsals from the cuneiform and cuboid bones 1,2. This may be modified by preserving the 4th and/or 5th metatarsal base/s, allowing peroneus brevis (and thus foot eversion) to be maintained 2,3. Tendon transfers (particularly of accessory slips) and gastrocnemius recession or Achilles tenotomy are also commonly performed to prevent biomechanical imbalance post-amputation 2-4."
