Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Peri-implant infections are severe complications after internal fracture fixation surgery. Detection of causative agents of orthopedic implant-associated infections (OIAI) is demanding. Several authors reported increased identification rates of bacterial prevalence using different sonication procedures compared to standard tissue cultures samples, especially for low grade infections.

On the author hand, contamination of implants without clinical signs of infection is reported in up to 30% during implant removals after uneventful fracture healing. The raised general questions are: 1.) Is a positive microbiological finding the result of contamination during the index surgery or during implant removal? 2.) Does contaminated implants without clinical or serological signs of infection have a pathological value?

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this prospective case study, the detection rates of different diagnostic tools for peri-implant contaminations during removal of syndesmotic screws should be compared and the clinical consequence of positive findings evaluated in follow up investigations up to 6 months.

Patients with ankle fractures (Weber B and C) treated operatively in our department by open reduction and internal fixation with plates and additional syndesmotic screw should be included. After patients´ informed consent, several microbiological samples should be taken for further microbiological analysis during the standard syndesmotic screw removal 6-8 weeks after the index surgery. At follow up of two weeks after screw removal a clinical examination and serological analysis for infection will be performed. The endpoint of study is fracture healing at six months.
