Objective:
To compare rates of fracture-related infection (FRI) and acute kidney injury (AKI) in patients with open fractures treated with ceftriaxone (CTX) monotherapy or piperacillin-tazobactam (PIP-TAZ) monotherapy.
Design:
Retrospective cohort study.
Setting:
Single Level I Trauma Center (2020-2023).
Patient Selection Criteria:
Adults who sustained an open fracture of the femur, tibia, humerus, radius/ulna, and foot fractures (metatarsals, calcaneus, talus) and underwent operative irrigation and debridement. Exclusion criteria were less than 6 months of follow-up, hospital transfers, primary amputation, receipt of vancomycin within the first 48 hours in addition to CTX or PIP-TAZ, and cases requiring vascular bypass, rotational or free flaps, or full-thickness skin grafts.
Outcome Measures And Comparisons:
Primary outcomes were rates FRI and AKI. Outcomes were compared between patients receiving prophylactic CTX versus PIP-TAZ monotherapy.
Results:
A total of 156 patients with open fractures were identified, of which 136 met inclusion criteria: 67 treated with CTX monotherapy and 69 with PIP-TAZ monotherapy. The mean age was 46.2 years (range: 18-86) in the CTX cohort and 41.6 years (range: 19-83) in the PIP-TAZ cohort, and males comprised 56.7% and 72.3% of each group, respectively. Differences between groups were limited to a longer mean follow-up duration in the PIP-TAZ cohort ( P < 0.001) and a higher prevalence of soil contamination in the CTX cohort (11.9% vs. 1.4%, P = 0.015). There were no statistically significant differences in rates of FRI (25.4% CTX vs. 29.0% PIP-TAZ, P = 0.501) or AKI (11.9% vs. 15.9%, P = 0.636) between groups. On multivariate analysis, diabetes (OR 6.62, P = 0.003) was independently associated with increased FRI risk, whereas soil contamination (OR 3.42, P = 0.180) and external fixation (OR 1.92, P = 0.163) demonstrated nonsignificant trends toward higher risk.
Conclusions:
In this retrospective cohort of patients with open fractures, ceftriaxone and piperacillin-tazobactam demonstrated comparable outcomes in both fracture-related infection and acute kidney injury. Diabetes was found to be a statistically significant risk factor for FRI.

Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
