Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Femoroacetabular impingement (FAI) is a clinical problem in which abnormal contact occurs between the thighbone and the hip socket. In intensive, mostly still young, male athletes, this problem seems to be related to a bony deformity on the head of this thighbone, a so-called CAM. FAI itself gives rise to pain symptoms, but in time can even lead to premature osteoarthritis. However, the cause of a CAM deformity itself, nor how FAI then arises, is insufficiently known. In view of FAI prevention and its better treatment, this project thus tries to better understand the underlying mechanisms. For this purpose, we will combine detailed biomechanical evaluations of specific movement patterns with advanced medical imaging and state of the art clinical evaluations to longitudinally follow up a group with a known high risk of developing a CAM deformity, being young male elite soccer players. Findings within this study will be additionally compared with similar analyses performed in patients with FAI. This research aims to thus form a basis to define novel (sports-specific) training schemes for the prevention of FAI, but also to define the actual treatment and rehabilitation plans in more patient-specific and a better-informed way.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a longitudinal follow-up study in which subjects are invited for data collection twice, the baseline time-point and the two years time-point.

Population:

12-16 years old male soccer players (40 elite level players , and 40 recreational level players)

In both data collection time-points the following measurements are preformed:

1. Clinical screening of hip joint
2. Radial MRI of bilateral hips
3. Biplanar and conventional x-ray Imaging of hip and pelvic region
4. Athlete-specific 3D motion analysis
5. Questionnaires on injury history and physical activity levels.
