Biomechanical Performance of BoneHelix<sup>®</sup> Compared with Elastic Stable Intramedullary Nailing (ESIN) in a Pediatric Tibia Fracture Model

Tibial shaft fractures are common injuries in the pediatric and adolescent populations. Elastic stable intramedullary nailing (ESIN) is the treatment of choice for cases that require surgical stabilization. A new intramedullary device, BoneHelix<sup>®</sup> (BH), may be an alternative fo...

Elastic stable intramedullary nailing (ESIN) is the treatment of choice for cases that require surgical stabilization.
