BACKGROUND: To identify the potential role of humeral retrotorsion (HRT) and range of motion (ROM) as a risk factor for shoulder overuse injury in elite youth handball players. The hypothesis was that increased HRT is associated with an increased risk of shoulder overuse injury.
METHODS: Over 2 seasons, 258 elite youth handball players (52% boys; age:14 ± 0.8 years) were included. Preseason assessment included HRT and glenohumeral internal and external (ER) rotational ROM using ultrasound and a manual goniometer. Sports-specific adaptations between male and female athletes and the dominant and nondominant shoulder were calculated. In addition, players completed standardized questionnaires over the 2018-2019 or 2019-20 season and reported any shoulder overuse symptoms using the Western Ontario Shoulder Index questionnaire.
RESULTS: Comparing male and female players showed significantly decreased HRT and decreased internal ROM in the dominant side of male athletes (P ≤ .027). No other difference was found. Significant side-to-side differences between the dominant and nondominant shoulder were found for HRT, internal rotation, and ER, regardless of sex (P < .001). For total range of motion, only female athletes showed a significant increase in the dominant arm (P = .032). The dominant side showed a significantly higher glenohumeral internal rotation deficit in male athletes than in female athletes (10° ± 17° vs 5° ± 10°, P = .011). Adaptations in HRT, ER gain, and total range of motion gain were not significant. Over the course of the 2 seasons, 20 athletes reported shoulder overuse injuries. Although glenohumeral internal rotation deficit was borderline nonsignificant (P = .056), none of the parameters tested were significantly associated with shoulder overuse injuries.
CONCLUSION: Despite significant side-to-side differences and sport-specific adaptations, individual preseason screening of humeral retrotorsion and soft tissue adaptations does not identify elite youth handball athletes at increased risk of shoulder overuse injury.
