Review Question - QID 218715

A 49-year-old accountant presents with symptomatic bunions that were previously treated by a podiatrist. She notes that her right side has healed well, but her more recently done left side has become more painful over the last three months with stiffness and loss of dorsiflexion at the first metatarsophalangeal joint. She "feels like a marble is stuck" between her second and third metatarsal heads when she puts weight on the foot and wants to be evaluated for revision surgery. The operative report states that a proximal crescentic metatarsal osteotomy was performed and fixed with two smooth wires that were pulled in the clinic. Which of the following is the most likely complication the patient has suffered that would account for her current chief complaints?
