Sacral stress fractures: an unusual cause of low back pain in an athlete.
METHODS
A case report of a sacral stress fracture causing low back pain in an athlete.


OBJECTIVE
To document the occurrence of sacral stress fractures in athletes and to recommend it in the differential diagnosis of low back pain, especially in runners and volleyball players.


BACKGROUND
Low back pain is common both in the general population and in athletes. Athletes place high physical demands on their bodies, which often lead to stress fractures. Sacral stress fractures can cause back pain and are often not included in the differential diagnosis of back pain.


METHODS
The authors were involved in the care and treatment of this patient and reviewed all medical records, radiologic tests, and related literature.


RESULTS
In a 16-year-old volleyball player with a 4-week history of low back pain, magnetic resonance imaging of her pelvis revealed a stress fracture of the left sacral ala. She was treated with nonsteroidal anti-inflammatory agents, rest, and conditioning exercises and had a good functional outcome.


CONCLUSIONS
Sacral stress fractures should be included in the differential diagnosis of athletes with low back pain, particularly runners and volleyball players. To the authors' best knowledge, this is the first report of a volleyball player with a sacral stress fracture. A review of the literature yielded 29 cases of sacral stress fractures in athletes, mainly runners.
