J Foot Ankle Surg. 2021 May-Jun;60(3):595-599. doi: 10.1053/j.jfas.2019.04.008. Epub 2021 Feb 8.

Abstract

Avascular necrosis (AVN) after bunion surgery is an unfortunate complication which can be devastating and painful. We present a case report of gradual medializing transport of the second metatarsal with external fixation to repair a large bone defect caused by AVN affecting >50% of the first metatarsal. The procedure was performed on a 49-year-old female who suffered AVN after failed bunion surgery. At 12-month follow up, first ray position and length were maintained. With respect to the second ray, there were no clinically significant issues. The second digit was mildly elevated but there was no frank instability of the toe or of the Lisfranc complex. The patient was pain free and had returned to her desired daily activities.
