Brief summary

The purpose of this research study is to find out if patients treated for nonunion fracture with autograft or allograft return to activity faster.

Detailed description

The goal of this multi-center prospective randomized controlled trial is to compare short and long-term outcomes of adult patients with long-bone nonunion treated with autograft versus allograft. The main question it aims to answer is: will patients who receive an allograft return to work faster than patients who receive an autograft to treat nonunion fracture. Participants will be randomized to one of two treatment groups and will complete follow-up surveys during their recovery.

Interventions

PROCEDUREAutograft

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.

PROCEDUREAllograft

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.

Inclusion criteria

* 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

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
Metabolic Equivalent for Tasks ScoreWeek 6Time 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.
Average Time to Return to Work/DutyWeek 6Average number of days it takes for participants to return to work/duty
Number of Participants Returned to WorkWeek 6Determined by asking whether subjects have returned to work

Secondary

MeasureTime frameDescription
Percentage of UnionWeek 6, Month 3, Month 6, Month 12Percentage of union will be assessed via radiographs and determined by the treating surgeon.
Time to UnionWeek 6, Month 3, Month 6, Month 12Number of days to union
Radiographic Union Scale in Tibial fractures (RUST) scoreMonth 12The RUST score ranges from a minimum score of 4 (definitely not healed) to a maximum score of 12 (completely healed). The final x-ray obtained within a 12-month period following injury will be uploaded to REDCap for review by a blinded panel of investigators from participating sites.
Number of Participants who Return to the Operating RoomWeek 6, Month 3, Month 6, Month 12Number of participants who return to the Operating Room after procedure
PROMIS-29 Subscale - Physical FunctionWeek 6, Month 3, Month 6, Month 12The PROMIS-29 scales will be scored using a T-score metric method. A score of 50 points represents the population average for each scale, and 10 points represent one standard deviation. Higher scores means higher physical function.
PROMIS-29 Subscale - AnxietyWeek 6, Month 3, Month 6, Month 12The PROMIS-29 scales will be scored using a T-score metric method. A score of 50 points represents the population average for each scale, and 10 points represent one standard deviation. Higher scores means a higher level of anxiety.
PROMIS-29 Subscale - DepressionWeek 6, Month 3, Month 6, Month 12The PROMIS-29 scales will be scored using a T-score metric method. A score of 50 points represents the population average for each scale, and 10 points represent one standard deviation. Higher scores means a higher level of depression
PROMIS-29 Subscale - FatigueWeek 6, Month 3, Month 6, Month 12The PROMIS-29 scales will be scored using a T-score metric method. A score of 50 points represents the population average for each scale, and 10 points represent one standard deviation. Higher scores means a higher level of fatigue.
PROMIS-29 Subscale - Sleep DisturbanceWeek 6, Month 3, Month 6, Month 12The PROMIS-29 scales will be scored using a T-score metric method. A score of 50 points represents the population average for each scale, and 10 points represent one standard deviation. Higher scores means a higher level of sleep disturbance.
PROMIS-29 Subscale - Pain InterferenceWeek 6, Month 3, Month 6, Month 12The PROMIS-29 scales will be scored using a T-score metric method. A score of 50 points represents the population average for each scale, and 10 points represent one standard deviation. Higher scores means a higher level of pain interference.
PROMIS-29 Subscale - Ability to Participate in Social Roles and ActivitiesWeek 6, Month 3, Month 6, Month 12The PROMIS-29 scales will be scored using a T-score metric method. A score of 50 points represents the population average for each scale, and 10 points represent one standard deviation. Higher scores means a higher ability to participate in social roles and activities.
Number of Resource UtilizationsWeek 6, Month 3, Month 6, Month 12Healthcare utilization, including new hospitalizations, emergency department visits, clinic visits, imaging, and physical therapy sessions will be documented at all follow-up visits
Pain Intensity ScoresWeek 6, Month 3, Month 6, Month 12Pain will be assessed using the Brief Pain Inventory (BPI). The BPI is a commonly used and validated 15-item measure of pain intensity and interference with daily life. Worst pain score 1-4 = mild pain, 5-6 = moderate pain, 7-10 = severe pain.
Veterans RAND 12 Item Health Survey (VR-12) ScoresWeek 6, Month 3, Month 6, Month 12The VR-12 is a measure of global health that correspond to seven domains: general health, physical functioning, role limitations, pain, fatigue, social functioning, and mental health. Together, these items are summarized into a Physical Component Score and a Mental Component Score. Scores range from 0-100 with higher scores indicating better physical and mental health functioning.
Work Productivity and Activity Impairment Questionnaire ScoresWeek 6, Month 3, Month 6, Month 12Participants who report return to work/duty will complete the Work Productivity and Activity Impairment Questionnaire, a validated instrument that measures work time missed and work and activity impairment due to health problems. Measures absenteeism, presenteeism as well as the impairments in unpaid activity because of health problem during the past seven days. The higher number of day equates to more health problems.
Number of ComplicationsWeek 6, Month 3, Month 6, Month 12Number of major complications, including infection, implant failure, unplanned or planned return to the operating room related to the nonunion procedure, deep venous thrombosis, or pulmonary embolism.
