Background: Stress fractures of the olecranon caused by repetitive stress force
have infrequently been reported as a cause of elbow pain in adult athletes,
engaged in throwing and pitching sports.
Purpose: We present the clinical and radiological features of a stress fracture of
the olecranon in an adult baseball player.
Study Design: a case report
Methods: We diagnosed as a stress fracture of the olecranon by clinical and
radiographic findings and treated surgically.
Results: The patient returned to playing baseball at a competitive level and was
asymptomatic four months after the first operation. However, the patient
re-injured the olecranon and a second surgical treatment was performed almost
one year after the first operation. After the second surgery, the patient returned
to baseball playing at a competitive level and was free from elbow symptoms.
Conclusions: We presented a stress fracture of the olecranon in a competitive
baseball player and suggested that surgical treatment is necessary.
