title: Stress fractures of the sesamoid bones of the first metatarsophalangeal joint in athletes.
abstract: Over a period of 11 years 15 cases of stress fractures of the sesamoid bones of the first metatarsophalangeal (MTP) joint were treated in athletes. The mean age of the patients was 22.3 years, and there were 9 males and 6 females in the series. All patients were athletes, who began to suffer from the symptoms during training without any trauma. Eight fractures were located in the medial, six in the lateral sesamoid bone, and in one case both sesamoids were affected. The diagnosis was performed on the basis of the history, symptoms, clinical examination, and radiological, or isotope scanning findings. Ten of the patients were treated conservatively by prescribing an avoidance of excessive physical activity and better training shoes. In five cases surgical excision of the fragmented painful sesamoid bone was performed. There were no complications in the series and the athletes could start gradually training 6-8 weeks after the operation. The histology showed fibrotic non-union at the fracture site and supported the diagnosis of stress fracture. Three of the conservatively treated athletes had mild symptoms in intensive training, others had a good end result.
