– See: Arthroscopic Acromioplasty – Lateral portal: – used for visualization of, or for insertion of instruments into, subacromial space, (usually for arthroscopic acromioplasty or for calcific tendinitis); calcific tendinitis); – the key to lateral portal placement is that it must allow triangulation over the entire undersurface of the anterior acromion; – if the portal is … Read more
– Technique: – best visualization of the shoulder joint is through the posterior portal; – portal usually is located 1.5-3 cm distal & 1-2 cm medial to postero-lateral tip of acromion; – further refine the proper location of the portal by finding the soft spot, using deep palpation of the … Read more
