Overview

The TrueLok Elevate Transverse Bone Transport System is a modular external fixation device designed for transverse bone transport. It promotes local vascular and wound healing through controlled corticotomy and gradual distraction. The system is intended for adult patients with bony and/or soft tissuedefects.
