RT Journal Article SR Electronic T1 Intertrochanteric hip stress fracture in a male ultramarathon runner JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e239594 DO 10.1136/bcr-2020-239594 VO 15 IS 1 A1 Jeffrey P Nadwodny A1 George Pujalte A1 Tais Garcia de Oliveira Bertasi A1 Tamara Huff YR 2022 UL http://casereports.bmj.com/content/15/1/e239594.abstract AB Stress fractures are injuries frequently seen in high-performance athletes, especially runners. In the femur, the most commonly affected locations are the femoral neck, condylar area and proximal shaft. Intertrochanteric fractures are much more common in the elderly population, especially among those with osteoporosis, but they can also be a result of high-energy repetitive mechanisms. We present a case of an intertrochanteric stress fracture in a young male runner. The diagnosis was suspected after persistent pain following his first marathon, and it was confirmed with an MRI. Operative fixation of the fracture was performed 22 days after the pain started, which allowed the patient to return to his activities, including 50 km marathon 4 months following the surgery.
