Review Question - QID 215772

A 55-year-old construction worker with diet-controlled type II diabetes mellitus presents to your office for evaluation of a painful bump over the lateral aspect of his forefoot. He has tried wide toebox shoes, padding/band-aids, and custom orthotics without significant long-term relief. On radiographs, he has a 4-5 intermetatarsal angle (IMA) of 13 degrees, a fifth metatarsal head width of 16mm, and a congruent fifth metatarsophalangeal (MTP) joint. What is the best treatment for this patient?
