[Bilateral symmetrical stress fracture of the ulna]

Good documentation is available concerning the prevalence, localisation and treatment of stress fractures. Stress fractures are much less common in the upper extremities than in the lower limbs. An unusual case of bilateral stress fractures in the ulnae in a patient aged 95 years is reported. These fractures are attributed to the use of a walking aid for a period of one year. The clinical features of stress fractures are discussed on the basis of the case history.
