To investigate how the range of motion (ROM) in the hip joints and lumbar spine is affected by continued elite alpine skiing in young subjects with and without MRI-verified cam morphology after a 2-year follow-up, emphasizing the significance of cam morphology.
Key Findings:
Young elite skiers with cam morphology showed a decrease in hip joint ROM over 2 years compared to those without cam morphology, with statistically significant differences in hip flexion and internal rotation observed between the two groups.
Interpretation:
The findings suggest that cam morphology may negatively impact hip joint mobility in adolescent elite skiers, potentially leading to increased risk of hip-related issues.
Limitations:
Small sample size (30 participants) may limit generalizability, and dropout of participants from baseline to follow-up could introduce bias affecting the results.
Conclusion:
Continued elite alpine skiing may exacerbate ROM limitations in adolescents with cam morphology, highlighting the need for monitoring and potential interventions, and suggesting areas for future research.
