One of the well-known postoperative complications that requires a number of prophylactic and curative treatments is infection. The implications of postsurgical infections are further exacerbated by the emergence of antibiotic-resistant strains. Reduced effectiveness of synthetic antibiotics has led to an interest in plant-based substances. Extracts obtained from have been shown to possess effective anti-infectious agents against bacteria frequently seen in bone infections. In this study, a fiber-based bone scaffold containing polycaprolactone, poly(lactic acid), and hydroxyapatite with oil at varying concentrations was developed. Solvent electrospinning was used to fabricate the fibers with the specified composition. According to FE-SEM analysis, fibers with average diameters of 751 ± 82, 1000 ± 100, 1020 ± 90, and 1223 ± 112 nm were formed and successful integration of oil into the fiber's structure was confirmed via FTIR. showed moderate susceptibility against the fibers with a maximum inhibition zone diameter of 11.5 ± 1.6 mm. MTT assay analysis exhibited concentration-dependent cell toxicity against fibroblast cells. In short, the antibacterial fibers synthesized in this study possessed antibacterial properties while also allowing moderate accommodation of CDD fibroblast cells at low oil concentrations, which can be a potential application for bone healing and mitigating postsurgical infections.

To measure the life quality, clinical-functional outcomes of a patient who had undergone acute reconstruction of radio scapho capitate (RSC), radio lunate (RLL) ligaments, using brachiorradialis tendon in treatment of radiocarpal fracture dislocation. 21-years-old, man with radiocarpal fracture dislocation in his left wrist, after motorcycle accident. Percutaneous screw fixation of the distal radius and acute reconstruction of the RSC and RLL was performed, assisted by arthroscopy.

A 33-year-old male patient developed distal femur chronic osteomyelitis with massive bone loss after an open grade-3b fracture. Following several failed treatments to eradicate infection, a tibial turn-up procedure was performed to provide a stable and functional stump. To avoid neurovascular problems, the popliteal vessels and sciatic nerve were moved medially, and the flap was rotated externally to decrease the collapse.

Bone regeneration is a multifaceted process involving the well-coordinated interaction of cellular functions such as the regulation of inflammation, the formation of new blood vessels, and the development of bone tissue. Bone regeneration is a multifaceted process involving the well-coordinated interplay of multiple cellular activities, such as inflammation control, blood vessel and bone tissue. Zhang developed a multifunctional hydrogel system embedded with bone marrow stromal cell-derived exosomes to address the challenges of large bone defects.

To investigate the clinical characteristics, treatment, and efficacy of spontaneous cerebrospinal fluid rhinorrhea (CFR) combined with aspiration pneumonia. In this case series study, a total of 8 patients diagnosed with spontaneous CFR combined with aspiration pneumonia were admitted to the Department of Otorhinolaryngology Head and Neck Surgery at Yuhuangding Hospital Affiliated with Qingdao University from March 2020 to March 2022. There were 3 males and 5 females, with ages ranging from 45 to 57 years.
