Freiberg's infraction is a rare disorder that arises mostly in adolescent athletes. We describe a 77-year-old woman with the collapse of second metatarsal head with similar clinical appearance to Freiberg's infraction. Radiological findings at initial visit of our hospital were normal. Her condition was obscure and magnetic resonance imaging showed the subchondral insufficiency fracture with bone marrow edema to the second metatarsal head. Despite the conservative treatment, the second metatarsal head collapsed. She was surgically treated with an osteochondral autograft without complications relating surgery. Furthermore, the histological findings showed that the site of collapse was considered to be secondary lesions resulting from the subchondral insufficiency fracture.
弗赖伯格骨折是一种罕见的疾病，主要发生在青少年运动员中。我们描述了一位77岁的女性，其第二跖骨头塌陷，临床表现与弗赖伯格骨折相似。我院初诊时的放射学检查结果正常。她的病情不明，磁共振成像显示第二跖骨头有软骨下不全骨折伴骨髓水肿。尽管进行了保守治疗，第二跖骨头仍发生了塌陷。她接受了自体骨软骨移植手术治疗，未出现与手术相关的并发症。此外，组织学检查结果表明，塌陷部位被认为是软骨下不全骨折导致的继发性病变。
