The aim of this study was to investigate the features of bone metabolism and their influence on the arterial wall stiffness in postmenopausal women with a controlled uncomplicated arterial hypertension (AH). The study involved 44 women (main group) with the mean age of 69.04±0.72 years and a postmenopausal duration of 18.4±0.85 years, suffering from an AH grade 2, and 30 healthy patients (control group), their mean age being 69.3±1.21 years, postmenopausal duration 19.4±1.18 years (p>0.05). All patients underwent general clinical and laboratory examination with determination of lipid level in blood. Pulse wave analysis (SphygmoCor) parameters , Bone mineral density (BMD) were assessed. The levels of 25(OH) D, parathyroid hormone, propeptide procollagen of type 1 aminoterminal (P1NP), b-isomerized C-terminal telopeptides (b-CTx), ionized calcium and phosphorus in serum were assessed. The data obtained from the study of the parameters of applanation tonometry and the structural and functional state of bone tissue in patients with an uncomplicated hypertension at the age of 69±3.30 years manifest the likelihood of joint pathogenetic mechanisms of developing atherocalcinosis, increased vascular stiffness and impending osteoporosis.

Bone is a common site for the metastasis of malignant tumors, and Single Photon Emission Computed Tomography (SPECT) is widely used to detect these metastases. Accurate delineation of metastatic bone lesions in SPECT images is essential for developing treatment plans. However, current clinical practices rely on manual delineation by physicians, which is prone to variability and subjective interpretation.

Objective: Treatment with transcutaneous osseointegrated prosthesis systems (TOPS) for short femoral amputation stumps aims to restore independent walking ability after proximal femoral amputation by direct bone-guided prosthesis anchorage. This cannot be safely achieved with conventional socket prostheses due to the mechanically inadequate socket contact surface.
Indications: Treatment of patients with short transfemoral stumps who cannot be mobilized sufficiently with conventional socket prostheses.

In current alloplastic total temporomandibular joint replacements (TMJRs) typically the lateral pterygoid muscle (LPM) insertion is sacrificed, affecting joint function. This study assesses a novel additively manufactured TMJR (CADskills BV, Gent, Belgium) designed to enable LPM reinsertion through a scaffold feature on the implant. Thirteen TMJRs were implanted in Swifter crossbreed sheep, with follow-up CT scans after 288 days to evaluate LPM reintegration.

The biomechanical properties of articular cartilage arise from a complex bioenvironment comprising hierarchically organised collagen networks within the extracellular matrix (ECM) that interact with the proteoglycan-rich interstitial fluid. This network features a depth-dependent fibril organisation across different zones. Understanding how collagen fibrils respond to external loading is key to elucidating the mechanisms behind lesion and managing degenerative conditions like osteoarthritis.

We aimed to explore the ultrasonographic features and risk factors of postoperative lower limb DVT in patients with lower limb fractures. Ninety patients with lower limb fractures admitted from January 1st, 2021 to June 30th, 2023 were selected.
