Abstract
A modular system for treating a bone includes a main body including a channel extending therethrough. A distal end includes a driving feature sized and shaped to engage a corresponding driving structure of one of first and second bone screws. The system also includes an inner shaft sized and shaped to be inserted into the channel and including a distal end including a retaining feature for engaging a corresponding retaining structure extending within a recess at a proximal end of the first screw. Furthermore, the system includes an outer shaft extending longitudinally and including a channel extending therethrough. The channel of the outer shaft is sized and shaped to slidably receive the main body therein and including a retaining feature extending along a distal end thereof. The retaining feature of the outer shaft engages a retaining structure extending along an exterior surface of the second screw.
