Hip microinstability, characterized by supraphysiologic movement of the femoroacetabular joint, has recently been recognized as a clinically relevant pathology. The potentially detrimental effects of its presence on joint health make identifying microinstability important; however, due to its multifaceted nature, screening for microinstability presents challenges. Musculoskeletal ultrasound offers an opportunity to visualize the arthrokinematics of the femoroacetabular joint on dynamic evaluation. Dancers may be particularly afflicted by microinstability due to the unique demands of their discipline. This study describes a method for evaluating femoral translation using dynamic ultrasound in adolescent dancers. One hundred forty-two dancers (117 females and 25 males) were recruited from a northeast high school dance program. Females mean age was 16.02 ± 1.06 years, mean BMI 20.35 ± 2.30 kg/m², and mean years of dance experience 10.91 ± 2.84 years. Males mean age was 15.84 ± 1.26 years, mean BMI 21.78 ± 2.84 kg/m², and mean years of dance experience 7.96 ± 2.82 years. Two hundred eighty-four hips were visualized under ultrasound imaging with the participants in both a neutral position and with the hip extended and externally rotated. The distance (mm) the femoral head was positioned anterior to the acetabulum was recorded for both these positions. The calculated difference in these values represented anterior translation. For female hips, the total mean anterior translation was 1.23 ± 2.01mm (-4.8 to 9.30 mm); for male hips, the mean of anterior translation was 1.39 ± 2.22 mm (-7.90 to 5.90 mm). This study identified a normative value range for hip anterior translational motion under dynamic ultrasound among a healthy population of adolescent dancers.

INTRODUCTION: Relative Energy Deficiency in Sport (RED-S) is a clinical syndrome that includes the many complex health and performance consequences of low energy availability (EA) in athletes, when there is insufficient caloric intake to meet exercise-related energy expenditure and to support basic physiologic functions. There is a high prevalence of urinary incontinence (UI) in female athletes and it is more common in female athletes than non-athletes. The objective of this study was to determine if low EA is associated with UI in a population of adolescent and young adult female athletes and to evaluate for an association between sport categories and UI. MATERIAL AND METHODS: 1000 nulliparous female patients, ages 15-30 years, presenting to a sports medicine subspecialty clinic, provided informed consent/assent to participate in a cross-sectional study involving a comprehensive survey, anthropomorphic measurements, and medical record review. Low EA was defined as meeting ≥1 criterion: self-reported history of eating disorder/disordered eating (ED/DE), and/or a high score on the Brief Eating Disorder in Athletes Questionnaire (BEDA-Q), and/or a high score on the Eating Disorder Screen for Primary Care (ESP). UI was assessed using questions adapted from the International Consultation on Incontinence-Urinary Incontinence Short Form (ICIQ-UI-SF), questions regarding timing of UI onset/duration, and a binary question regarding UI during sport activities. A total of 36 sport types were included in the survey and sub-divided into categories. RESULTS AND DISCUSSION: Of the 1000 female athletes surveyed, 165 (16.5%) reported a history of experiencing UI during athletic activities. ICIQ- UI-SF responses indicated that 14% (137/1000) of the cohort experienced slight incontinence, 4% (35/1000) moderate incontinence, and 2 athletes experienced severe incontinence. There was a significant difference between UI categories in age (p = 0.01), low EA (p < 0.001), and sport category (p < 0.001). Females who had low EA had twice the likelihood (OR = 1.97; 95% CI = 1.39 to 2.81; p < 0.001) of UI compared to those with adequate EA, controlling for sports category and menstrual dysfunction. Females who participated in high impact sports were 4.5 times more likely (OR = 4.47; 95% CI = 2.29 to 8.74; p < 0.001) to have had UI compared to females who participated in ball sports, controlling for EA and menstrual dysfunction. CONCLUSIONS: UI during athletic activities is a common problem among nulliparous adolescent and young adult female athletes, occurring in 16.5% of female athletes surveyed. UI was significantly associated with low EA across all sport categories. Sport type was significantly associated with UI, with the highest impact sport group demonstrating a higher prevalence and symptom severity compared to other sport categories.
