Making a Charcot CROW Walker Boot

Dennis Johnston, Orthotist and Assistant Prosthetist and his team at Collier-Laurence Orthotics and Prosthetics demonstrate the construction of the CROW Walker Diabetic AFO. Fabricating on-site gives us the ability to keep a tight rein on quality control. From the first fitting, our patient’s comfort and education is the highest priority. Step 1: Custom-shaping a cast of a patient’s leg Step 2: Layer plys on cast of patient’s leg, as demonstrated by orthotic/prosthetic technician Rey Linares Step 3: Cut out trilame (lining) material Step 4: Heat molding the foot bed is a 2-person job Step 5: Mark and cut excess material, demonstrated by orthotic/prosthetic technician Hung Dzoan Step 6: Skyving and shaping Step 7: Add foot bed to cast, measure Step 8: Heat molding lining material Step 9: Heat molding outer material for both bottom and top pieces Step 10: Cutting open outer and lining layers into two pieces Step 11: Skyving and filing edges Step 12: Cutting out, attaching and shaping boot rocker bottom Step 13: Hand-placing rivets, straps and d-rings The CROW walker is for those who have a neuropathic ulcer or those who have been diagnosed with Charcot Foot. This offloading AFO is made from a cast impression and is designed with a soft footbed and cushioned liner. The brace itself is rigid with a rocker bottom to allow for normal heel to toe walking. The walker reduces forces in the foot and ankle and reduces pressure on the bottom of the foot to help heal and prevent ulcers. 85% of lower-limb amputations are preceded by a foot ulcer so it is extremely important to follow the doctors instructions for foot care and wearing the CROW walker as prescribed. Those with Diabetes and other risk factors should have their feet examined regularly so that Charcot Foot symptoms and possible treatment can be discussed. As Charcot Foot develops, the bones in the foot weaken and fracture easily. Since pain sensation is likely decreased due to peripheral neuropathy, the person does not feel the pain associated with the injury. Deformity may occur so treatment is a serious and timely matter.
