Isolated metatarsal head resection for diabetic forefoot ulcers have never been a good solution as this article points out. This type of approach is typically only used with osteomyelitis (bone infection), but as this study reveals the adjacent metatarsals must be protected from transfer lesions. This is best accomplished by equinus management and forefoot off-loading with the use of custom orthoses and diabetic shoes.
