5Determination of entry point and opening of the canal

Open the humerus

A cannulated drill bit is recommended for opening the proximal humerus. This drill bit should be inserted over the previously placed guide wire. It should be advanced into the proximal medullary canal.

Alternatively, an awl may be used to open the humerus.

Take care not to displace the tuberosity fracture during passage of awl or drill.
