Bilateral stress fracture of the ulna in an adult weightlifter: a case report.

Bilateral stress fractures of the ulna are extremely rare and have only been described in non-adults. In this case report we present a young adult weightlifter who reported bilateral stress fractures of both ulnae after increasing his training frequency and load. Stress fractures of the ulnae are examples of bone stress injuries due to repetitive muscle pull. The diagnosis can be made by radiography, isotope bone scan, CT or MRI. Thorough training analysis and adaptation is essential to treat this rare injury. Return to full activity can take up to three months.
