Case Reports and SeriesLong-Term Fever After Hallux Valgus Surgery Secondary to Titanium Allergy: A Case Report and Review of the Literature
Section snippets
Case Report
An 18-year-old male patient presented with a prolonged low-grade fever that had lasted >7 months after surgical treatment for left hallux valgus. For transfer metatarsalgia caused by left hallux valgus, the patient had undergone Scarf and Akin osteotomy with 24-mm Extremifix cannulated screws (YZB [medical device registration product standard], standard 0105-2013, as reported by the manufacturer, Double Co., Xiamen City, China) in our hospital 22 months previously. He reported the onset of
Discussion
Metal allergy, which can be histologically described as a type of aseptic lymphocyte-dominated vascular-associated lesion, is characterized by diffuse perivascularly located lymphocyte infiltration with necrosis and a limited numbers of macrophages (6). It is a type IV allergic reaction caused by metal corrosion and a lesion resulting from the constant release of ions into the tissue environment 7, 8. The severity of the reaction depends on the material and the sensitivity of the patient (9).
