Stress Fracture Risk May Be Modifiable

Stress Fracture Risk May Be Modifiable
The incidence rate for stress fracture injuries among females was nearly three times greater when compared to males. Knee rotation and abduction angles when landing were both associated with the rates of lower-extremity stress fractures, as were reduced knee and hip flexion angles, and increased vertical and medial ground reaction forces. “Lower extremity movement patterns and strength have previously been associated with stress fractures and overuse injuries; however, our study is one of the first to identify dynamic knee rotation and frontal plane angles as important prospective risk factors for lower extremity stress fractures.
