- Brief Summary
The goal of this randomized clinical trial is to study the best treatment for open lower leg fractures to prevent infection. The main questions it aims to answer is if treating tibia fracture patients with a calcium sulfate antibiotic depot is better at preventing infection that the standard of care.
- Detailed Description
This research is a randomized clinical trial aimed to reduce the frequency of fracture related infections following open tibia fracture. The proposed test methods for infection reduction is use of an antibiotic depot placed inside the bone at the time of final fracture treatment. This is in addition to standard of care wound care, fracture fixation with intramedullary nailing, and peri-operative systemic antibiotics.
This prospective randomized clinical trial will compare outcomes between patients treated with an antibiotic depot placed inside the bone at the time of final fracture fixation and those treated with traditional standard of care intramedullary nailing.
The target population for the proposed study is patients with severe open tibia fractures (Type II or III) who require definitive fixation with intramedullary nail recruited form one of the participating sites during the index hospitalization.
One group will be treated prophylactically suing a calcium sulfate antibiotic depot at the time of definitive fixation, while the second group will be treated with a standard of care intramedullary nail without the antibiotic depot.
Participants will be followed for 12 months (data capture includes patient interviews and clinical data capture from the treatment team and medical record at baseline, 6 weeks, 3 months, 6 months, and 12 months).

Veterans RAND 12 Item Health Survey (VR-12) Domain--Pain week 6, month 3, month 6 and month12 The VR-12 is a measure of global health that correspond to seven domains. Together, these items are summarized into a Physical Component Score and a Mental Component Score. The PCS and MCS are normalized using TScore and are on a 0-100 scale. The interpretation is based on a population mean of 50 and standard deviation of 10. Higher scores represent a better outcome.
Radiographic Union Scale in Tibial fractures (RUST) score week 6, month 3, month 6, and month 12 The 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.
PROMIS-29 Subscale--Pain Interference week 6, month 3, month 6 and month12 The PROMIS-29 scales will be scored using a T-score metric method. PROMIS Pain Intensity T-scores from 20-55 are considered within normal limits, 55-60 is mild, 60-70 is moderate, and 70+ is severe. 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 Pain Interference (PROMIS-PI) scale measures the extent to which pain hinders an individual's engagement with physical, mental, cognitive, emotional, recreational, and social activities.

International Physical Activity Questionnaire (IPAQ) Baseline, 3 month, 6 month, 12 month IPAQ measures the total amount of physical activity completed in a 7 day period by calculating the minutes per week in in each physical activity level domain (walking, moderate and vigorous) by a metabolic equivalent energy (MET) expenditure estimate.
Walking = 3.3 x number of walking minutes x number of walking days Moderate activity= 4.0 x number activity minutes x number of days Vigorous activity = 8 x number of activity minutes x number of days Total = Walking MET-min/wk+moderate MET-min/wk+vigorous MET-min/wkPROMIS-29 Subscale--Physical Function week 6, month 3, month 6 and month12 The 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. The sum of the PROMIS results in the raw score, which lies between 4 and 20 - Higher scores means higher physical function; lower scores represent lower physical function
Percentage of Union week 6, month 3, month 6 and month 12 Union is the gradual process of bone regeneration after a fracture. Percentage of Union, as determined by the treating surgeon, will be assessed via radiographs. Recorded by surgeon as yes/no answers.

Together, these items are summarized into a Physical Component Score and a Mental Component Score. The VR-12 is a patient-reported instrument from which physical and mental health component summary scores (PCS and MCS) are derived. The PCS and MCS are normalized using TScore and are on a 0-100 scale. The interpretation is based on a population mean of 50 and standard deviation of 10. Higher scores represent a better outcome. The VR-12 items assess physical functioning, role limitations due to physical or mental health problems, pain, energy, mental health, social functioning, and general health.
PROMIS-29 Subscale--Physical Function: Anxiety week 6, month 3, month 6 and month12 The PROMIS-29 scales will be scored using a T-score metric method. The PROMIS Anxiety item banks assess self-reported fear (fearfulness, panic), anxious misery (worry, dread), hyperarousal (tension, nervousness, restlessness), and somatic symptoms related to arousal (racing heart, dizziness). 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; lower scores represent lower level of anxiety
PROMIS-29 Subscale--Fatigue week 6, month 3, month 6 and month12 The PROMIS-29 scales will be scored using a T-score metric method. A higher PROMIS T-score represents more of the concept being measured. For negatively-worded concepts like fatigue, a T-score of 60 is one SD worse than average. By comparison, a fatigue T-score of 40 is one Standard Deviation better than average. 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. Mean fatigue scores in the four study samples ranged from 18.5 to 22.8 on the PROMIS (PROMIS) Fatigue-Short Form (F-SF) (potential range 7-35); from 14.8 to 47.8 on the MFSI-SF (potential range 24-86); and from 3.6 to 6.6 on the BFI (potential range 0-10).
