Soft tissue and bone infections continue to be a serious complication in orthopedic and trauma surgery. Both can lead to a high burden for the patients and the healthcare system. Musculoskeletal infections can be induced by intraoperative contamination, bacterial contamination of open wounds or hematogenous bacterial spread. During the recent decades, advances were achieved in the understanding of pathogenesis and antibiotic resistance. Despite some progress in the diagnosis and advancing of therapeutic concepts, groundbreaking successful improvement of treatment concepts is still missing. Current therapy concepts are based on the two pillars consisting of surgical debridement with joint or bone reconstruction as well as prolonged antibiotic therapy. An improved understanding of both host and pathogen-related factors leading to treatment failure is essential in musculoskeletal infections. Therefore, this review aims to give an overview of pathogen-related pathophysiology in musculoskeletal infections. It describes defense strategies of pathogens such as (1) biofilm, its development, characteristics, and treatment options. In addition, (2) characteristics of small colony variants and (3) intracellular bacteria are highlighted. Lastly (4) an outlook for potential and promising future therapeutic strategies is provided.

Introduction: The prostate is densely innervated like many visceral organs and glands. However, studies to date have focused on sympathetic and parasympathetic nerves and little attention has been given to the presence or function of sensory nerves in the prostate. Recent studies have highlighted a role for sensory nerves beyond perception of noxious stimuli, as anterograde release of neuropeptides from sensory nerves can affect vascular tone and local immune responses.

Objectives: Fracture-related infection (FRI) is a feared complication in orthopaedic trauma surgery. They are associated with multiple surgical interventions and prolonged antibiotic treatment duration, and hence, increased costs. The objective of this study was to assess the costs of FRI treatment in a Tertiary Swiss Trauma Center and to identify the variables associated with increased costs.

Lumbar disc herniation (LDH) is a common degenerative condition causing low back pain (LBP) due to nerve compression. Previous studies show conflicting findings regarding the multifidus (MF) muscle's microscopic changes in LDH patients. So, this study aimed to compare the affected MF to the adjacent MF on the ipsilateral and contralateral sides in LDH patients and examined correlations with clinical features of LBP.

Soft tissue and bone tumors are rare, and their low frequency and diverse histological types make conducting large-scale clinical trials challenging. Patient-derived xenografts (PDX), entailing implantation of cancer specimens in immunocompromised mice, are emerging as a valuable translational model because PDX keeps the original tumors' character and drug sensitivity. We sequentially transplanted 166 surgical and biopsy specimens from orthopedic surgeries, including 138 soft tissue and bone tumors (81 malignant, 23 intermediate, and 34 benign), 16 metastatic bone tumors, 9 hematological malignancies, and 3 non-tumor tissues.

Background Managing primary bone and soft tissue sarcomas in pediatric patients poses significant challenges, with surgical resection remaining essential for cure. While limb salvage surgery has emerged as the standard approach, concerns persist regarding post-operative complications. Our study aims to evaluate the 30-day morbidity and mortality of limb salvage surgery in pediatric tumor patients, bridging critical knowledge gaps and contributing to enhancing the standard of care in low- and middle-income countries (LMICs).
