BAASIK technique: an innovative single needle technique of performing shoulder corticosteroid injections.

The novel BAASIK (B-Botchu,Bipin, A-Agrawal, A-Ankit, S- Sindhura, I-Iyengar, K- Kapil) technique is a combined ultrasound-guided injection into the subacromial-subdeltoid (SASD) bursa and the biceps tendon sheath to treat shoulder pain associated with biceps tendonitis/tendinopathy, subacromial bursitis, rotator cuff impingement or to determine the source of shoulder pain. This technique aims in reducing shoulder pain, improving functional activities and enhancing treatment delivery. A single-entry supine ultrasound-guided injection of the subacromial-subdeltoid (SASD) bursa and biceps tendon sheath involves using a single needle insertion point to access both structures for therapeutic injection. This technique could become a favoured alternative technique, rather than  subjecting patients to two needlesticks and preparing two separate injections to address often concomitant pathologies.
