The management of soft tissue damage during fracture treatment requires surgical proficiency and meticulous care adhering to established treatment protocols. This approach is paramount for minimizing the risk of potentially limb- or even life-threatening complications such as fracture-related infection (FRI) in all age groups. There is a general consensus on essential measures such as wound assessment, surgical debridement and early use of antibiotics. Treatment should always be based on the correct classification of the fracture and the corresponding soft tissue injury, but needs to be adapted to the individual patient considering general health status, secondary diagnoses and currently available treatment options.

In orthopaedic trauma, fracture-related infections (FRI) are still dreadful challenges that can cause non-union, amputation and even death. Standardization of general treatment strategies for FRI is still lacking. ⋯ Surgical treatment, antibiotic therapy and host optimization for FRI were summarized and discussed. The goal of this review is to provide an overview and summary of current approaches of FRI management and to make suggestions on FRI prevention and treatment based on multidisciplinary principles.

The diagnosis of fracture-related infections (FRI) is challenging and requires interdisciplinary efforts. Many diagnostic approaches are based on the algorithms established for prosthetic joint infections (PJI). Data specific to FRI are limited. ⋯ In addition to bacterial detection, the study of host tissue factors has the potential to transform the diagnostics of FRI by facilitating the assesment of clinical significance in clinical samples. The integration of host tissue analysis into microbiology reports has great potential to improve the diagnosis of FRI. This mini-review describes the potential improvement of diagnostic techniques by integrating new approaches into the diagnostic algorithm of fracture-related infections.

The present minireview aims to provide a context for imagination of the timespan for bone infection evolution from the origin of cellular bone tissue to modern orthopedic surgery. From a phylogenetic osteomyelitis-bracketing perspective, and due to the time of osteocyte origin, bacteria might have been able to infect the skeleton for approximately 400 million years. Thereby, bone infections happened simultaneously with central expansions of the immune system and development of terrestrial bone structure. ⋯ Orthopedic surgery, including arthroplasty and osteosynthesis, favor introduction of bacteria and prosthesis/implant related infections are thus anthropogenic infections (anthropogenic; resulting from the influence of human beings on nature). In that light it is important to remember that the skeleton and immune system have not evolved for millions of years to protect titanium alloys and other metals, commonly used for orthopedic devices from bacterial invasion. Therefore, these relatively new orthopedic infection types must be seen as distinct with unique implant/prosthesis related pathophysiology and immunology.

Phage therapy (PT) continues to attract interest in the fight against fracture-related infection (FRI), particularly for recurring infections that have not been resolved using conventional therapeutic approaches. The journey PT has taken from early clinical application in the pre-antibiotic era to its recent reintroduction to western clinical practice has been accelerated by the increased prevalence of multi-drug resistant (MDR) pathogens in the clinic. ⋯ The challenges for PT, for example the most optimal application technique and dosing, are also discussed and underscore the importance of personalized approaches and the urgent need for more robust clinical evidence. Future perspectives, including phage engineering and innovative delivery systems will be discussed, as they may broaden the applicability of PT to a point where it may become a standard rather than an option of last resort for orthopedic infection management.
