Anterior shoulder approach of hydro-dilation technique by Yoong et al. had few issue rises from this technique; (i) administering an intra-articular shoulder injection through a thickened coracohumeral ligament result in significant resistance and patient discomfort, and (ii) risk of injecting into long head of biceps tendon is higher. This technical report is to describe a new approach using subacromial subdeltoid (SASD) bursa hydro-dilation at rotator interval instead of intra-articular injection. This technique utilizes fenestration of coracohumeral ligament followed by SASD hydro-dilation. Thirteen patients underwent the procedures reported significant outcomes in pain score (from mean VAS of 5.61 to 2, p value < 0.001) and range of motion (mean forward flexion from 76.61 degree to 149.07, p value < 0.001, and mean abduction from 60.61 degree to 94.61, p value < 0.001). This method presents a potentially less technically demanding and time-efficient alternative to existing treatments.
Mohamad et al. (Sat,) studied this question.
