Abstract
Fragstellung: To examine the safety and accessibility of the sternoclavicular joint by arthroscopy for
debridement of the joint in a cadaveric model.
Methodik: An inferolateral and superomedial portal was created for debridement of the sternoclavicular joints in
12 cadaveric specimens. After debridement, the specimens were dissected with needles positioned in the portal
tracts. The distance between the needles and bony landmarks, tendons and ligaments was measured. The
integrity of the posterior capsule and the extent of resection of the intra-articular disc were evaluated
macroscopically.
Ergebnis: Both portals were found to be safe while allowing good access to the joint. The superomedial portal
went through the tendon of the sternal part of the sternocleidomastoideus muscle and the inferolateral portal
through the pectoralis major muscle. The portals entered the capsule respectively medial and lateral to the
anterior sternoclavicular ligament. The posterior capsule was never perforated. Macroscopic evaluation showed a
stable rim of the intra-articular disc after debridement.
Schlussfolgerung: In this cadaver study, arthroscopy of the sternoclavicular joint is shown to be a minimally
invasive procedure allowing debridement of the intra-articular disc without damaging the ligamentous structures of
the joint.
