G. Declercq et al., A posteromedial working portal for arthroscopic subacromial decompression and acromioclavicular joint arthroplasty, ARTHROSCOPY, 15(4), 1999, pp. 456-458
Arthroscopic subacromial decompression is traditionally performed through a
posterolateral viewing portal and a lateral working portal. We describe th
e same procedure by using a posterolateral viewing portal and a posteromedi
al working portal. Because this portal is in the same sagittal plane as the
ipsilateral acromioclavicular joint, it allows performing an arthroscopic
excision arthroplasty of this joint.
