Brief Summary
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...
Detailed Description
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 wit...
Eligibility Criteria
Inclusion
- Patients 18-65 years old with an open tibia fracture involving diaphysis (if patient has a bilateral tibia fracture and both require a bone graft, then each will be randomized separately).
- Tibia fractures with a circumferential bone defect of at least one centimeter in length compromising at least 50% of the circumference of the bone.
- The definitive treatment of the tibia fracture must be with an intramedullary nail (may have temporary external fixation prior to IM nail placement).
- Patients whose treatment plan includes placement of a bone graft between 6 to 16 weeks after their initial injury.
- Patients who have no evidence of infection by clinical examination (defined as active infection at the operative site, purulent drainage from the fracture or evidence of active osteomyelitis at the time of bone graft).
- Patients who are independent in living and ambulation prior to injury.
- Patients who are English speaking.
- Patients who are willing to provide consent and available for follow-up for at least 12 months following definitive surgical procedure.
Exclusion
- Patients who are pregnant or lactating.
- Patients with known hypersensitivity to rhBMP-2 or bovine type I collagen.
- Patients with a history of tumor, a resected or extant tumor, an active malignancy, or patients undergoing treatment for malignancy.
- Patients who are skeletally immature (\<18 years of age or no radiographic evidence of epiphyseal closure).
- Patients with inadequate neurovascular status, e.g. high risk of amputation.
- Patients with compartment syndrome of the affected limb.
- Patients with immune deficiency or history of auto-immune disease,
- Patients who have undergone treatment of any other investigational therapy within the month preceding implantation or planned within the 12 months following implantation.
- Patients unable to return for required follow-up visits.
- Patients who have medical co-morbidities that preclude treatment with a general anesthetic.
- Patient who is pending incarceration or who is incarcerated.
- Patients with an active infection at the operative site, purulent drainage from the fracture or evidence of active osteomyelitis at the time of bone grafting.
- Patient has intraoperative positive gram stain or an elevated CRP after laboratory screening for infection.
- Patient has segmental defects longer than 5cm in length.
- Patients who have segmental defects that require more than 60 cc of bone graft.
- Patients who require more than one large kit of rhBMP-2 at time of surgery.
- Patient's anticipated treatment plan also includes the use of other procedures to promote fracture healing, e.g. ultrasound, magnetic field or electrical stimulation.
- Patient's tibia fracture has been treated with additional fixation beyond the intramedullary nail, e.g. plates, wires or screws.
- Patients who have pathological fractures; a known history of Paget's disease or known history of heterotropic calcification.
- Patients with a Glasgow Coma Scale less than 15 (less than fully awake) at the time of informed consent.
- Patients with previous hardware in place that prevents placement of an intramedullary nail for treatment of the tibial shaft fracture.
- Patients with prior use of INFUSE.
- If the patient is a female of child bearing potential:
- Does she have a negative pregnancy test (administered within 72 hours prior to surgery)?
- Has she agreed to use adequate contraception for a period of at least 1 year following implementation of rhBMP-2?
