- Abstract:
- Objectives: High performance overhead sports result in repetitive high loading patterns. This subsequently causes relevant prevalence of shoulder pathologies in the adult athlete. However, there is still a lack of imaging-based data with respect to structural adaptations and alterations in an a-/ oligosymptomatic junior elite athlete group. The aim of this study was to evaluate early imaging findings in the dominant and adominant shoulder of high performance competitive junior javelin and volleyball athletes. Material/Methods: 30 healthy high performance junior elite athletes competing at national and international level were included. All subjects participate in high intensive sports-specific training for a minimum of 2 years. Two subgroups were composed of 16 male volleyball players and 14 mal javelin throwers. The mean age (±SD) of the volleyball and the javelin group was 16.9 (±1.0) and 17.6 (±0.8) years, respectively. No major trauma or absence of surgeries were deteced in medical history. All subjects underwent questionnaire-based interviews and a comprehensive clinical examination of both shoulders including ASES and Rowe score. Bilateral shoulder imaging data were performed using a 3T-MRI (Verio, Siemens Medical Solutions, Erlangen, Germany). The native imaging protocol included T1w coronal, T2w sagittal, T2w DESS 3D axial, PDw axial, and coronal sequences using a dedicated shoulder coil in supine position. Results: Clinical evaluation was absent of any specific shoulder pathology and all subjects had excellent results regarding ASES and Rowe score demonstrating a-/ oligosymptomatic shoulder function. However, MRI revealed bony cysts > 3 mm at the posterolateral aspect of the rotator cuff insertion site in 71.5 % of the dominant shoulders of the javelin athletes in comparison to only 14.3 % in the non-dominant shoulder. In contrast, only 12.6 % of the volleyball players showed corresonding cyst formations < 3 mm in their dominant and 6.3 % in their non-dominant shoulders. No rotator cuff lesions and no major chondral damage were seen. 2 volleyball players had asymptomatic SLAP-lesions in the dominant and non-dominant shoulders, respectively. Conclusions: Even acknowledging that bony cysts at the posterolateral aspect of the humeral head are structural alterations with a high prevalence in adults, it is remarkable that these alterations can be already seen in adolescents, but predominantly at the dominant site and only in javelin athletes. Therefore, the specific motion of throwing in javelin and hitting in volleyball seem to cause different structural adaptations of the shoulder. If these bony cysts close to the rotator cuff insertion site provoke early subtle lesions of the adjacent rotator cuff, a concept of preventive arrangements has to be established to minimize early career-compromised shoulder pathologies, which are well-known especially in javelin.
