Efficacy of a new porous titanium compression screw using an ovine osseointegration model

Fracture fixation of small bones remains challenging for pathologies relating to tenuous retrograde blood supply. For example, acute scaphoid fractures are among the most common traumatic injuries and account for 50-80% of carpal injuries[1]. Solid screws without bone grafting are often ineffective in cases of osteonecrosis. The objectives of this study were to evaluate bone healing and strength of fixation of a new porous titanium (Ti) compression screw compared to a conventional titanium compression screw in cortical bone and in challenging models of gap-healing and osteonecrosis.Peer reviewed: NoNRC publication: Ye
