Metastatic tumours often come from breast, lung, kidney and thyroid gland while direct invasion of the sternum often occurs from lymphoma, bronchogenic carcinoma, breast cancer, pleural and mediastinal malignancy (2). The skeleton is a common site of metastasis in lung cancer. The lesions are usually osteolytic and often present with The sternum is a flat T-shaped bone that sits at the front of the chest and connects to the ribs with cartilage. It forms part of the rib cage, a series of bones that This study proves that the sternum is a reliable bone to determine the sex of a person by measuring the length and breadth of manubrium and body of sternum in both sexes. Background & objectives: Determination of sex is a vital part of medico-legal practice. The objective of the study was to obtain cut off values for determination of sex by measuring The sternum (also known as the breast bone) is a bone that lies in the anterior midline of the thorax. It functions to protect organs in thorax and to provide attachment points for the Sternum pain can be caused by many various reasons. If the reason is an injury or inflammation then you may feel more pain if you apply pressure to the breastbone. You could also hear the sternum bones clicking. Sometimes the muscles and nerves connected to the sternum can cause pain, and stretching can make breastbone pain Mediastinal lymphadenopathy is the swelling of lymph nodes in the chest, specifically the mediastinum (the area between the lungs containing the heart, trachea, and esophagus). It is a sign of an underlying medical condition. Some of the conditions that may cause mediastinal lymphadenopathy include an infection such as tuberculosis, an The sternum is a long, flat bone at the center of your chest. It is sometimes referred to as the breastbone. The sternum's main function is to protect the vital organs that sit behind it

Sternum Pain: What Is It? What’s Causing My Sternum Pain? Costochondritis. Other musculoskeletal conditions. Acid reflux. Respiratory conditions. Sternum piercing is a relatively new body modification trend that has gained popularity in recent years. The piercing is done horizontally through the cartilage of the breastbone, and can be decorated with a variety of different jewelry styles. Because of its location, sternum piercings can be quite painful and take longer to heal than other Performing chest compressions may result in the fracturing of ribs or the sternum, although the incidence of increased mortality from such fractures is widely considered to be low. [ 42 ] Artificial respiration using noninvasive ventilation methods (eg, mouth-to-mouth, bag-valve-mask [BVM]) can often result in gastric insufflation Pectus excavatum is a structural deformity of the anterior thoracic wall in which the sternum and rib cage are shaped abnormally. This produces a caved-in or sunken appearance of the [HOST] can either be present at birth or develop after puberty. Pectus excavatum can impair cardiac and respiratory function and cause pain in the chest and A sternal foramen (SF), which arises from the incomplete fusion of the cartilaginous neonatal sternum, is a relatively common anatomical variation found in % to % of all individuals. SFs are usually located at the lower third of the sternal body and their average diameter is mm. An SF is subclinical; however, its close proximity to Sternum, in the anatomy of tetrapods (four-limbed vertebrates), elongated bone in the centre of the chest that articulates with and provides support for the clavicles BACKGROUND. The use of steel wires is the most common technique for sternal closure after median sternotomy. There are, however, imminent risks when using such wires [1, 2].Owing to traction and shear forces during thoracic motion, the wires may fracture or even cut through the sternum, necessitating sternal refixation

Hormones. Hormonal factors, such as exposure to estrogen, can influence your risk, too. This includes early menstruation, late menopause, and certain hormone replacement therapies. Estrogen receptor positive breast cancers are a type of breast cancer that reacts to estrogen Sternum pain is usually caused by problems with the muscles and bones near the sternum and not the sternum itself. Pain felt just behind or below the sternum is called substernal pain and is sometimes caused by gastrointestinal problems. Some of the most common causes of sternum and substernal pain are: costochondritis Respiration. suspended respiration or breathing technique if possible. centering point. midway between the jugular notch and the xiphoid process. dependent on rotation around cm left of the midline. collimation. laterally around 15 cm to include the body of the sternum. superoinferiorly to include the jugular notch and the xiphoid process On the desktop app, navigate to Preferences in the settings menu.

You can choose either an image or a video as your background Background The origin of powered avian flight was a locomotor innovation that expanded the ecological potential of maniraptoran dinosaurs, leading to remarkable variation in modern birds (Neornithes). The avian sternum is the anchor for the major flight muscles and, despite varying widely in morphology, has not been extensively studied The anterior mediastinum is located between the sternum and the pulmonary root, and the posterior mediastinal space extends posteriorly from a line connecting the anterior surfaces of the thoracic vertebral bodies. The middle mediastinum is the remaining portion. On the frontal thoracic radiograph, the mediastinum is divided in the superior
