Rib stress fracture in a female athlete caused by bouncing the barbell in bench press exercise: A case report.

Rib stress fractures can occur in sports involving repetitive trunk muscle contractions. Few documented cases show rib fractures from repetitive upper-limb training. This report presents a case of a rib stress fracture from micro blunt trauma during bench press exercises. The patient was a 24-year-old elite female sprinter with a history of left navicular stress fracture and secondary amenorrhea treatment a year prior. She modified her bench press technique to involve bouncing the barbell on her rib cage. Within weeks, she experienced anterior chest pain, exacerbated by sneezing. Computed tomography revealed a fifth rib fracture with callus formation. After refraining from bench presses for 4 weeks, her chest pain subsided, allowing her to resume upper-limb training. When athletes performing bench press exercises experience chest pain, rib fractures should be considered, even without acute trauma. Additionally, research on the safety of the bouncing bench pressing technique is required.
