Purpose To analyze the shoulder alterations of professional tennis players during the competition season and to compare the diferences between their dominant vs. non-dominant shoulders, as well as gender and age diferences. Methods Two-hundred and seventy shoulders of (78 men and 57 women) professional active tennis players were assessed during 3 ATP and WTA tournaments. Main variables studied: long head of biceps (LHB) tenderness and synovitis; glenohumeral internal rotation deicit (GIRD), total range of motion (TRM), external rotation (ER) and scapular dyskinesis (DK). Secondary variables: shoulder dominance, gender, age, training hours, ranking, type of backhand. LHB tenderness and synovitis were assessed by clinical and ultrasound examination, TRM with goniometer and DK by dynamic observation. Results LHB tenderness of the dominant shoulder was present in 35% of all players, being more prevalent in women (47.4%) than men (26.9%) p = 0.023. LHB synovitis of the dominant shoulder was present in 20.2% of all players without diference between genders (n.s). High prevalence of GIRD was found in both dominant (87.4%) and non-dominant (56.3%) shoulders, being more prevalent in the dominant shoulder p = 0.00005. TRM was decreased in both dominant (144.5° ± 20.2°) and nondominant shoulders (161.2° ± 18.9°) p = 0.00005. ER was normal in dominant (93.8° + /9.3°) and non-dominant shoulders (93.4° + /8.4°) (n.s). DK was present in 57.7% of dominant and 45.9% of non-dominant shoulders (n.s). The combination of LHB alterations, GIRD and DK in the dominant shoulder was present in 13.3% of the participants. There were no signiicant diferences between younger (< 22 years) vs older players (≥ 22 years). Conclusion Professional tennis players actively playing sufer a high prevalence of LHB inlammation, GIRD, scapular dyskinesis and decreased TRM in their dominant and non-dominant shoulders. The LHB is a signiicant cause for anterior shoulder pain in this population. Women sufer more LHB tenderness than men. Young players are as afected as older players. Level of evidence Level IV.

Por lo tanto, las luxaciones AC de cualquier grado pueden afectar al ritmo escapular y a su biomecánica.En este artículo se revisa el concepto de disquinesis, cuáles son los criterios para su evaluación y las diferentes clasificaciones.Además, se profundiza en la relación entre la luxación AC y la disquinesis. Los aspectos anatómicos, la presencia aumentada de la disquinesis en el contexto de las diferentes lesiones de la AC y las hipótesis sobre sus causas. Finalmente se comentan los resultados del tratamiento conservador y quirúrgico en el contexto de la luxación AC grado 3 en cuanto a la disquinesis.Type III acromioclavicular separation Rehabilitation Surgical treatment a b s t r a c tThe scapulothoracic and acromioclavicular (AC) joints are inter-related to form the shoulder suspensory complex. Therefore, patients with any kind of AC dislocation may present with biomechanical scapular alterations and suffer scapular dyskinesis.In the present article, the concept of dyskinesis is reviewed, as well as the evaluation criteria and the different types of classifications.The relationship between acromioclavicular joint dislocation and dyskinesis is also assessed.
