TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Management of large and deep heel ulcers (LDHUs) is a challenge in patients with diabetic foot lesions. We assessed outcomes of a treatment protocol to save feet with LDHUs from amputation.', 'We managed LDHUs (larger than 3 cm(2)) in diabetic feet using a multidisciplinary approach consisting of medical and surgical management, including revascularization and amputation, if necessary. For deep heel infection and/or gangrene, we frequently debrided and drained the deep spaces of the heel, as needed. In patients with non-ischemic feet, we made a flap from the heel pad with a broad pedicle. When satisfactory granulation tissue covered the base of the heel and the inner surface of the flap, we sutured the heel flap to its base.', 'We managed 37 feet with LDHUs among 384 patients. Twenty-nine patients (78.4%) had neuropathy, 6 (16.2%) had ischemic diabetic feet, and 2 (5.4%) had both neuropathy and ischemia. Twelve (32.4%) had septic diabetic feet. We performed two femoropopliteal bypasses, 2 infrapopliteal bypasses, and 1 distal bypass (crural) for ischemic heel ulcers. Thirty-three of the 37 feet with heel lesions (89.2%) were salvaged using this multidisciplinary approach. These 33 LDHUs healed after 4 to 7 months (median, 6 months). Transtibial amputation was performed for 4 feet (10.8%; 2 ischemic and 2 neuropathic cases).'] Need large and deep diabetic heel ulcers lead to amputation?
