Tibial Delayed Healing Pivotal Clinical Trial

The purpose of this study is to evaluate the INFUSE/MASTERGRAFT™ Delayed Healing Device as an alternative/replacement to autograft in the treatment of tibial delayed healing. A subject will be considered to have tibial delayed healing when he/she is at least six months from the date of the most recent surgical intervention and has shown no signs of radiographic healing for at least three months. Radiographic signs of healing for this study are defined as either the progressive disappearance of fracture lines or the development of cortical continuity \[bridging bone\] at the site. All prospective patients must require surgical treatment with rigid internal fixation \[reamed IM nail or plate/screws\] and bone grafting.
