Introduction: Osteoporosis is a very common disorder of skeleton, which can be caused by various metabolic disturbances, malnutrition, immobilization, endocrine disorders, bone marrow diseases, connective tissue disorders, and, in some cases, by inappropriate therapy. The aim of this investigation was to evaluate the relationships between the mineral content in the alveolar bone and serum osteoporosis in chosen patients.
Material And Methods: The study included an experimental and a control group of patients who were submitted to internal and prosthodontic therapy. The plan of therapy was to extract anticipated parodonthopathic teeth, taking samples of the alveolar bone and its analysis by spectrometry. At the same time the biochemical analyses of the blood were performed.
Results: Before the therapy, due to negative remodeling, values of mineral content in decalcified bone tissue and serum were significantly lower than in the control group. After the therapy, the quality of the bone tissue was improved, with increased contents of mineral substances.
Discussion And Conclusion: Disorders of mineral metabolism are very important for osteoporosis. This disorder may involve entire skeleton, especially stomatoghnatic complex. Therefore osteoporosis is one of very important illnesses in dentistry, especially in prosthodontics, because of the supporting nature of bone tissue for all types of dental prostheses.

Background: Irisin is an exercise-induced myokine that elicits beneficial effects of exercise in fat, bone, and the brain. Previous work suggests that extracellular heat shock protein 90a (Hsp90a) mediates irisin-receptor interaction in bone and fat. Despite this, it remains unclear if Hsp90a is necessary for irisin signaling in the brain.

Purpose Of The Study: Open (incisional) biopsies have long been accepted as the gold standard in diagnosing bone and soft tissue tumors. However, the main disadvantage of this method is that it can lead to increased contamination, hematoma, infection, and pathological fracture. Compared to open biopsies, percutaneous core needle biopsies are less invasive, do not require hospitalization, have low costs and low complication rates, and there is no need for wound healing in cases that require radiotherapy.

Purpose Of The Study: Lisfranc is a challenging injury both diagnostically and surgically, with sparse long-term literature evidence of surgical practice. We aim to review our long-term specialist orthopaedic institutional experience of Lisfranc injuries and the surgical management of this complex injury, specifically considering surgical outcomes as per radiological and clinical assessment.
Material And Methods: We present data from a prospectively maintained institutional database, reviewing patients who underwent operative fixation for Lisfranc injury between April 2014 and August 2020.

Purpose Of The Study: The annual number of spinal fusion procedures has been increasing and is well documented worldwide. The O-arm is slowly becoming the standard for transpedicular screw insertion. The accuracy and safety of this method have been confirmed by many studies.

Purpose Of The Study: Temporary hemiepiphyseodesis using figure-eight plates is currently one of the main surgical techniques to correct axial deformities of lower limbs in paediatric patients. Comprehensive analysis, correct indication and monitoring of treatment are the basic prerequisites for successful therapy. The aim of the study was to analyse parameters that could become an alternative to standard parameters used nowadays, namely the inserted screw angle (SA), and a new parameter - condylar ratio (CR).
