Short vs. Long Antibiotic Treatment of Implant-free Osteoarticular Infections

2018-08-01 14:26:14 | BioPortfolio


We test the working hypothesis if 4 weeks of systemic antibiotic treatment in implant-related orthopaedic infections is non-inferior to 6 weeks after complete removal of the infected implant. Randomization 1:1.


Osteoarticular infections related to orthopaedic implants are associated with substantial morbidity, prolongation of hospital stay, and additional costs. Due to the increasing number of patients with orthopaedic implants in Switzerland, similar to the rest of Europe and elsewhere, the number of infections is expected to increase. While the surgical treatment of these infections has been well studied, the ideal duration of antibiotic therapy after removal (explantation) of the infected implant remains unknown. For almost 40 years, the recommended total duration of post-explantational antibiotic therapy has been 6 weeks. This recommendation is based on expert's personal experience rather than on prospective randomized studies. Shorter treatment would decrease antibiotic-related adverse events and costs hospital stay for patients awaiting an eventual reinsertion of a new implant. If physicians and surgeon prescribe antibiotics for 6 weeks, this duration should be at least supported by evidence.

Medical and Biotech [MESH] Definitions

Insertion of an implant into the bone of the mandible or maxilla. The implant has an exposed head which protrudes through the mucosa and is a prosthodontic abutment.

Endosseous dental implantation where implants are fitted with an abutment or where an implant with a transmucosal coronal portion is used immediately (within 1 week) after the initial extraction. Conventionally, the implantation is performed in two stages with more than two months in between the stages.
