It is contacted with the soft tissue near intervertebral foramen, has certain protective effect to exiting nerve root, but duckbilled working column is at soft group
It is walked in knitting apart from too long, lacks effective stabilization function, bone drill can squeeze duckbilled work when mill sells processus articular superior veutro sclerotin
Casing is deviated to intervertebral foramen soft tissue side, causes processus articular superior veutro sclerotin mill pin to be not thorough, and then the sleeve portion that works is not good enough,
Cause work sleeve portion undesirable.
There are one common features for latter two bone drill system, once bone road is established, position is undesirable, and change bone road will become
It obtains very difficult.
