Limitations and Risks of the Technique

Limitations •The surgeon must be familiar with complex shoulder arthroscopy procedures and techniques. •Steeper learning curve. •Requires a specifically designed guide. •May take a longer operating time.

Risks • Brachial plexus injury. In order to avoid this, one has to: o stay close to the bone during coracoid graft harvesting; and o go lateral while inserting the Wissinger rod from the posterior portal during the subscapularis split. •Subscapularis injury: to avoid iatrogenic damage during split, one has to introduce the Wissinger rod through the lower portion of the muscle tissue. •Graft breakage: This can be avoided by tensioning the graft under direct visualization.
