Brief summary: This is a prospective, single-center, double-blind randomized clinical trial aimed at evaluating the efficacy and safety of the extended-release antibiotic device, STIMULAN, in preventing infections in patients with open fractures. The study will enroll 40 patients from IRCSS San Raffaele's Emergency Department and Orthopedics and Traumatology Unit. Patients will be stratified into high-risk and low-risk infectious subgroups and randomized into either the intervention group receiving the antibiotic device or the control group receiving no device. The follow-up period will last for 5 days, with data collection at specified intervals. Standard laboratory tests will be utilized to monitor the patient's inflammatory response.

Detailed description: This study is a prospective, single-center, randomized clinical trial with a double-blind design for both the patient and the evaluator. The aim is to assess the efficacy and safety of the extended-release antibiotic device STIMULAN in preventing infections in patients with open fractures.

The trial will be a randomized study that will enroll two cohorts of patients with open fractures, sourced from both the Emergency Department of IRCSS San Raffaele and the Orthopedics and Traumatology Unit. Fractures will be classified according to the Gustilo Classification. Patients requiring surgical repair of the exposed fracture will be randomized to receive either the extended-release antibiotic device or no device at all. The randomization of this study is stratified, with a 1:1 ratio, and 40 patients will be divided into two groups:

Intervention group: extended-release antibiotic device Control group: no device

Two stratification subgroups will be included:

High-risk infectious subgroup Low-risk infectious subgroup For the definition of stratification, please refer to Section 9.1, Risk Assessment Table for Stratification.

Patients will be followed for a duration of 5 days, and follow-up data will be collected at established intervals. According to recent studies, the onset of initial infections occurs between 24 and 72 hours following the episode of open fracture. Therefore, a 5-day period is deemed a reasonable time frame for constant monitoring. Standard-of-care laboratory tests such as white blood cell count, C-reactive protein, erythrocyte sedimentation rate, and procalcitonin will also be collected and analyzed to determine the patient's inflammatory response.

Eligibility criteria: Inclusion Criteria:
