Postoperative infection following volar locking plate fixation of closed distal radius fractures: a retrospective cohort study of infection rates and antibiotic prophylaxis practice.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDistal radius fractures are among the most common surgically treated upper-extremity fractures, and volar locking plate fixation is the predominant operative technique. Although perioperative antibiotic prophylaxis is widely used in orthopaedic surgery, procedure-specific evidence for closed distal radius fractures remains limited. Contemporary data regarding postoperative infection rates and antibiotic prophylaxis practice following volar locking plate fixation are scarce. The aim of this study was to describe postoperative infection rates following volar locking plate fixation of closed distal radius fractures and to report contemporary patterns of perioperative antibiotic prophylaxis use in routine clinical practice.
methodsThis retrospective cohort study included consecutive adult patients undergoing volar locking plate fixation for closed distal radius fractures at a single center between January 2022 and December 2024. Patients were grouped according to receipt of perioperative antibiotic prophylaxis, reflecting routine clinical practice rather than predefined treatment allocation. The primary outcome was postoperative surgical site infection within one year of surgery. Secondary analyses described antibiotic prophylaxis use and patient, surgical, and surgeon-related characteristics.
resultsA total of 474 consecutive patients were included, of whom 237 received perioperative antibiotic prophylaxis and 237 did not. One postoperative surgical site infection occurred, corresponding to an overall infection rate of 0.2% (95% confidence interval [CI] 0.0-1.2). The infection occurred in a patient who did not receive antibiotic prophylaxis, was superficial, and resolved following treatment with oral antibiotics. No deep infections were observed. Substantial variation in prophylaxis use was observed among surgeons despite uniformly low infection rates across the cohort.
conclusionsPostoperative infection following volar locking plate fixation of closed distal radius fractures was rare in this contemporary cohort. The findings provide descriptive data on postoperative infection rates and perioperative antibiotic prophylaxis practice in routine clinical care. Although the study was not powered to evaluate the effectiveness of antibiotic prophylaxis, the observed low infection burden may help inform future research on infection prevention and antibiotic stewardship in distal radius fracture surgery. LEVEL OF EVIDENCE: III. CLINICAL TRIAL NUMBER: Not applicable.
