OrthoXel founders co-author exciting new tibial fracture research protocol published in JB&JS

OrthoXel is thrilled to have three of its founding members’; Charles Daly, Hannah Dailey and James Harty, co-author this article published in the Journal of Bone and Joint Surgery which focuses on Virtual Mechanical Testing Based on Low-Dose Computed Tomography Scans for Tibial Fractures.

The authors have been pioneering innovative approaches to orthopaedic trauma outcomes assessment to overcome the persistent challenge of quantitative outcomes assessment which faces orthopaedic trauma.

In comparison to traditional Patient Reported Outcome Measures (PROM) and Radiographic Union Scale in Tibial (RUST) scoring, virtual mechanical testing with low-dose CT scans provides a quantitative and objective structural callus assessment that reliably predicts time to union and may enable early diagnosis of compromised healing.

Disclosure: Funding to support study management was provided by a grant from OrthoXel, however, no OrthoXel devices were utilized in this study.
