Stress fractures occur mostly in track and distance runners, athletes who take part in field sports, gymnasts, dancers, and military recruits
Consider the diagnosis in sports people with risk factors for bone injury and progressively worsening localised bone pain
Women with the “female athlete triad” are especially at risk of bony stress injury
Magnetic resonance imaging is the most sensitive and specific imaging modality for diagnosing stress fractures
Stress fractures with low risk of non-union can be managed in primary care by modifying sports activity and reducing risk factors
Involvement of a specialist is necessary for fractures at high risk of non-union and operative fixation may be considered
The annual incidence of overuse injuries in track and field athletes is estimated to be 3.9 per 1000 training hours, with a prevalence of 76%,w1 and 10-20% of consultations in sports medicine practice are for stress fractures.1 Stress fractures are also common among army recruits.
With the advent of magnetic resonance imaging, stress fractures are diagnosed earlier and more readily than they were in the past, and early surgical treatment is increasingly considered as a management option for patients who are at high risk of fracture non-union. Rapid and accurate diagnosis of stress fractures is important to prevent propagation of the fracture, and early effective treatment may reduce time away from training and participation in sport. Experts think that overtreatment of low risk stress injuries and undertreatment of high risk injuries both occur and lead to unnecessary time away from training.2 In addition, increasing participation of non-athletes in endurance sports such as marathon running has led to an increase in stress injuries among non-professional sportspeople.
We review the diagnosis and management of stress injuries of the lower limb, drawing on evidence from randomised trials, non-randomised intervention studies, observational studies, …
