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.

Fracture related infection (FRI) remains one of the most challenging complications of orthopaedic trauma surgery. Several factors contribute to FRI development but, among those, particularly interesting from the orthopaedic surgeon's perspective is the contribution of mechanical stability and timing of fracture fixation. These are indeed crucial factors both in prevention and treatment of FRI and are directly influenced by the surgeon's work. ⋯ The same applies to the ideal timing of temporary or definitive fixation which varies according to the clinical scenario considered. In the present narrative review, we described the influence of mechanical stability on both FRI pathophysiology and on the decision making of FRI treatment. In addition, we analysed the impact of the timing of fracture fixation on the risk of FRI development particularly in those clinical scenarios where it has been shown to be specifically relevant, such as fractures affecting segments with poor soft tissue envelope, open fractures, damage control orthopaedics, and the need for soft tissue coverage.

Fracture-related infections (FRIs) are complex challenges in orthopedic and trauma surgery, driving ongoing advancements in diagnostics, therapeutics, and management strategies. This scoping review examines recent progress and future directions in FRI management. Diagnostic enhancements encompass standardized definitions, improved biomarkers, advanced microbiological techniques, and innovative imaging modalities. ⋯ Patient optimization, multidisciplinary approaches and specialized reference centers play vital roles in comprehensive FRI management, particularly crucial in resource-constrained settings. Collaboration and investment in research and technology are imperative for harnessing the full potential of these advancements and improving global FRI management outcomes. Addressing these complexities necessitates a multifaceted approach integrating clinical expertise, technological innovation, and global cooperation to optimize patient care and mitigate the burden of FRI worldwide.

Multicenter Study
Etiologies of non-traumatic extremity compartment syndrome: A multi-center retrospective review.
Determine the etiologies of non-traumatic extremity compartment syndrome (NTECS), understand the demographics of NTECS patients, describe their diagnostic workup and treatment, and establish their rate and cause of in-hospital mortality. This is a retrospective cohort study of all patients diagnosed with NTECS at two level 1 trauma centers between January 2006 and December 2019. Data pertaining to the etiology of NTECS, patient demographics, diagnostic and treatment modalities, and in-hospital mortality were collected from electronic medical records. ⋯ While uncommon, many etiologies of NTECS exist and often manifest insidiously. 13% of patients who develop NTECS will require a skin graft / flap, or extremity amputation. 20 % of patients who develop NTECS die during their hospitalization. High clinical suspicion and future research in this field are necessary to improve clinical outcomes for these patients. Level IV: Retrospective review.

This paper evaluates the accuracy and safety of a long bone fracture reduction robot under different surgical modes. ⋯ Based on CT imaging verification, the accuracy of the robot in both autonomous and master-slave surgical modes meets clinical requirements. Future work will focus on further optimizing the robot system.
