Outcome Measures
Primary Outcomes (12)
Metabolic Equivalent for Tasks Score
Time to return to work/duty will be measured using the the International Physical Activity Questionnaire (IPAQ).The IPAQ is a validated, self-report measure that captures detailed information about participation in a wide range of physical activities, including the number of days and amount of time spent in the previous 7 days. Responses for each type of physical activity are then transformed into the number of Metabolic Equivalent for Tasks (METs), and a METs/week is calculated for each patient.

Interventions
Surgeons will decide on the location and method of donor site based on the clinical situation. Most commonly, bone graft will be harvested from the anterior or posterior iliac crest or utilizing the Reamer Irrigator Aspirator in an appropriate long bone. Surgeons may choose to harvest autograft from proximal tibia or distal femur. Donor site location is at the discretion of treating surgeon for patients who randomize to autograft. This treatment arm will not include local autograft only. For large bone defects requiring expansion of autograft with allograft, this will be allowed and recorded. We will use intent-to-treat for statistical analysis of those with allograft expansion of autograft. This autograft will be applied to the nonunion site using the surgeon's typical technique. Internal fixation, revision of fixation, and/or augmentation of fixation will be performed at the discretion of the surgeon.
Allograft bone will consist of cancellous or corticocancellous sterile packaged human cadaveric bone. No bone morphogenetic protein, bone marrow aspirate, or other biologic augment will be added. Demineralized bone matrix may be added at the surgeon's discretion. This allograft will be applied to the nonunion site using the surgeon's typical technique. Internal fixation, revision of fixation, and/or augmentation of fixation will be performed at the discretion of the surgeon.
Eligibility Criteria
You may qualify if:
- Patients 18 years or older
- Long bone (tibia, femur, and humerus) nonunion appropriate for either study treatment: to be treated with bone graft harvested from a remote site or using reamer harvester (RIA)
- Nonunion surgery to be performed at least five months after initial fracture fixation
- Prior operative fixation of fracture
- Radiographic apparent bone gap (RABG) of \>5cm
You may not qualify if:
- Patient that speaks neither English nor Spanish
- Patients whose treatment plan includes local autograft only (available callus from the nonunion site or no planned bone graft)
- Known active infection (defined as any clinical signs or symptoms of active infection, such as fevers, wound redness, warmth, swelling, induration or drainage, and abnormal while blood cell count, erythrocyte sedimentation rate, or C-reactive protein) being treated with antibiotics
- Body mass index greater than 50
- Patients unlikely to follow-up due to homelessness, or planning follow-up at another institution
- Prisoner
