Urethral hemangiomas are rare and benign tumors, probably originating from a unipotent angioblastic stem cell. They can vary in size and the clinical appearance can range from asymptomatic lesions to urethral bleeding or gross hematuria. We present the case of an 18-year-old male, with a history of urethral bleeding. Cystourethoscopy revealed a solitary bulging mass into the lumen, about 6 cm far from the external meatus. Doppler study confirmed that the lesion was in communication with the vessels of the left spongious body. The patient underwent surgical removal of the lesion. The post-procedure Doppler study revealed an inflammation-based remodeling of the spongoius urethra and the absence of the previous vascular connection. At the time of publication the patient is still symptom-free. The surgical removal of urethral hemangiomas is by far the technique of choice for treating such lesions in young patients, thus avoiding side effects of LASER treatments.

A biomechanical study of locking spongious screws and failure rates are higher than expected in plate fixation.

Locking plates have a rapidly growing process especially in the past decades and results are satisfactory especially in the osteoporotic bones compared to non-locking compression plates. There are many forms of failure in the fracture fixation of locking plates, and screw pull-out is one of the main failure reasons. In this study, we aim to investigate pull-out failure in locking plates using locking spongious screws.

Background: Gold standard for determining bone density as a surrogate parameter of bone quality is measurement of bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA), most commonly performed on the lumbar spine (L1-L4). Computed tomography (CT) data are often available for surgical planning prior to spine procedures, but currently this information is not standardized for bone quality assessment. Besides, measuring the Hounsfield-Units (HU) is also of great importance in the context of biomechanical studies.

Department of Anatomy, Faculty of Medicine, Hacettepe University, Ankara, Turkey.
Background: Nutrient arteries pass through the nutrient foramina and reach the spongious part or medullary cavity of the bones. The arterial blood supply and nutrient foramina of the ilium have not been well described in the literature. The aim of this study is to define the numbers and localizations of nutrient foramina of the ilium on the internal surface in accordance with the pelvic brim, as well as the external surface, and furthermore the distances between these foramina with certain anatomical landmarks.

The aim of this study is to examine the stresses that will occur under occlusal forces on the cortical bone, spongious bone and the subperiosteal implant systems made of Titanium and%60 Carbon fiber reinforced Polyether ether ketone (PEEK) material. Two different models of subperiosteal implant systems on maxilla made of Titanium and %60 Carbon fiber reinforced Polyether ether ketone (PEEK) material. As a result of vertical and oblique forces, the stress values and distributions on the subperiosteal implant systems and bone were examined.

Within the niche, HSCs interact with various cell types such as osteoblasts, endothelial cells, macrophages, and mesenchymal stromal cells (MSCs), which maintain HSCs in a quiescent state or sustain their proliferation, differentiation, and trafficking, depending on body needs. In physiological conditions, the BM niche permits the daily production of all the blood and immune cells and their admittance/ingress/progression into the bloodstream.
