Osteochondroma are the most common benign primary bone tumor. They are bony outgrowths surrounded by a characteristic cartilaginous cap, most commonly arising from the long bones. They are most often asymptomatic, usually discovered as incidental findings before the third or fourth decade of life. Although the exact pathogenesis is not fully established, there have been reports of these tumors arising after incidents such as fractures, trauma, radiation, and stem cell transplants. There have been only a few cases describing the development of osteochondroma after traumatic events. This report presents a documented case of an osteochondroma arising at the site of a previous femoral fracture, 10 years after the initial trauma.
骨软骨瘤是最常见的原发性良性骨肿瘤。它们是由特征性软骨帽包绕的骨性赘生物，最常发生于长骨。它们大多无症状，通常在生命的第三个或第四个十年之前作为偶然发现被检测到。尽管确切的发病机制尚未完全明确，但已有报道称这些肿瘤在骨折、创伤、放疗和干细胞移植等事件后出现。仅有少数病例描述了创伤事件后骨软骨瘤的发生。本报告呈现了一例有记录的病例，该骨软骨瘤发生于既往股骨骨折部位，距初次创伤已有10年。
