a study on Tibial Fractures
The purpose of our study is to evaluate the use of recombinant human bone morphogenetic protein 2 (RhBMP-2) as compared to standard ICBG in the treatment of severe open tibia fractures with a critical size bone defect (at least one centimeter in length compromising at least 50% of the circumference of the bone).
RhBMP-2 vs. Autograft for Critical Size Tibial Defects: A Multicenter Randomized Trial
Open tibia fractures have a 15% or higher rate of not healing. Those fractures which do not heal are typically treated with bone from the hip (iliac crest autograft; or ICBG). The use of ICBG bone with the treatment of delayed unions/non-unions with critical defect, although successful, has its drawbacks. The bone graft sources are limited and the procedure is associated with additional operating room time plus a second incision with increased risk of infection, post operative pain and increased hospital stay. The purpose of this study is to determine if Rh-BMP2, a new bone graft substitute, is at least as effective as using bone from the hip (autograft) to help promote healing of open, tibia (shin bone) fractures.
What is the relative effect of rhBMP-2 versus autogenous ICBG on rates of union in patients with critical size defects following tibial shaft fractures?
Null hypothesis #1: rhBMP-2 has the same union rate when used in critical-sized defects as does ICBG.
What is the relative effect of rhBMP-2 versus autogenous ICBG on infection rates in patients with nonunion or critical size defects following tibial shaft fractures?
Null hypothesis #2: The infection rate in open tibias with critical-sized defects treated with rhBMP-2 and autogenous ICBG are the same.
What is the economic impact of the use of Rh-BMP 2 for tibial fractures with critical sized defects?
Null hypothesis #3: There will be no difference in the economic cost of the treatment of critical sized defects using the RhBMP-2 versus iliac crest bone graft.
