Correlation of MRI grading of bone stress injuries with clinical risk factors and return to play: a 5-year prospective study in collegiate track and field athletes.

Background: Bone stress injuries are common in track and field athletes. Knowledge of risk factors and correlation of these to magnetic resonance imaging (MRI) grading could be helpful in determining recovery time.

Purpose: To examine the relationships between MRI grading of bone stress injuries with clinical risk factors and time to return to sport in collegiate track and field athletes.

Restoration of menses with nonpharmacologic therapy in college athletes with menstrual disturbances: a 5-year retrospective study.

Background: Functional hypothalamic amenorrhea is common among female athletes and may be difficult to treat. Restoration of menses (ROM) is crucial to prevent deleterious effects to skeletal and reproductive health.

Objectives: To determine the natural history of menstrual disturbances in female college athletes managed with nonpharmacologic therapies including increased dietary intake and/or decreased exercise expenditure and to identify factors associated with ROM.
