Anterior shoulder dislocation (TASD) is the most frequently dislocated joint in the human body. According to literature data, he risk of recurrent dislocations is the highest in young active patients, up to 94% within the first two years. Most patients sustain anterior capsulolabral complex detachment (Bankart lesion) with or without bone avulsions and osteochondral lesion on the humeral head on the posterosuperior part (Hill Sachs lesion), leading to instability problems after the primary dislocation. For diagnosis and further treatment solutions, it is important to evaluate the size of bone lesion after the first-time anterior shoulder dislocation by CT.
The commonly used treatment method after the first-time TASD is immobilisation. There is no consensus on the length and type of shoulder immobilisation in the literature. Randomised studies reveal a significant reduction in instability risks in the case of operative treatment following the primary TASD. The choice of the operative technique depends on the size of bone defect: soft tissue stabilisation (Bankart operation) and/or bone fragment fixation (if possible), arthroscopic or open. In the case of large bone defects in the cavitas and humeral head bone block technique (Latrjet, Bristow) is used.
