Primary Outcome Measures:
  • Change in intramedullary vascular volume and new bone growth based on CBCT [ Time Frame: 2, 8 & 18 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: November 2006
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patients who have received a structrual allograft or vascularized fibular autograft surgery to reconstruct their tibia, femur, ulna/radius or humerus for treatment of a bone tumor.
Device: Cone Beam CT Scan
The Cone Beam Computerized Tomographic (CBCT) device utilizes computerized tomographic technology, a special digital imaging plate and a computer to create a three-dimensional image. The special imaging plate and software allow for small details to be imaged without tissue overlap.

Detailed Description:

The purpose of this study is to investigate quantitative vascular cone beam CT(CBCT) in a clinical pilot of patients that have received a structural allograft for bone cancer or a vascularized structural autograft for bone cancer or traumatic injury. Development of a minimally invasive, longitudinal outcome measure to quantify intramedullary vascular volume and cortical bone volume of structural allografts in patients is required to translate "revitalizing" structural allograft in clinical trials. Our novel vascular CBCT will be able to demonstrate the significant differences between vascularized fibular autografts vs. structural allografts in patients that will undergo structural grafting. These data will be used to devise a power calculation for a definitive clinical trial to evaluate the efficacy of the revitalizing allograft.
