tion of the heart, and particularly of the right ventricle, when the heart is in its correct central position. If during intra-uterine life the heart is not central and during development lies to the left side, leaving the mediastinum empty, there will be no positive force to elevate the sternum, but rather a negative pressure which will suck it in. The ribs and sternum ossify early, but the co...

We report the case of a 74-year-old female patient diagnosed with a giant cell tumor of the sternum. The clinical and radiological presentation was indicative of a primary tumor of the sternum. The patient underwent complementary tests and surgery. The pathological examination confirmed the diagnosis. Commonly observed in the long bones of the appendicular skeleton, this type of tumor is charac...

Access from the right chest is generally easier. In this case however, the thymoma was predominantly left-sided and therefore a left-sided approach was preferred. The anesthetist places a double lumen tube to allow isolation of the required lung. The patient is placed with the chest elevated to an angle of around 30 degrees. This allows the plane between the sternum and thymus to be developed e...

Introduction: Deep sternal wound infections (DSWI) are a rare but devastating complication after median sternotomy. Minor perfusion in bone and soft tissue, especially after recruiting the internal mammary artery for bypass supports the development of wound infection and nonunion of the sternal bone. The aim of the study was the macroscopic and radiological presentation of the vascular system s...

INTRODUCTION Sternal fractures are a painful condition which can result in pulmonary morbidity if not treated promptly. The management of isolated fractures has changed from hospital to home-based treatment, provided other major injuries have been excluded. Pain management is the mainstay of treatment. In this case report, we describe how a parasternal block under ultrasound guidance for sterna...

Chondrocyte differentiation is strictly regulated by various transcription factors, including Runx2 and Runx3; however, the physiological role of Runx1 in chondrocyte differentiation remains unknown. To examine the role of Runx1, we generated mesenchymal-cell-specific and chondrocyte-specific Runx1-deficient mice [Prx1 Runx1(f/f) mice and alpha1(II) Runx1(f/f) mice, respectively] to circumvent ...

BACKGROUND When traditional vascular access methods fail, emergency access through the intraosseous (IO) route can be lifesaving. Fluids, medications, and blood components have all been delivered through these devices. We sought to compare the performance of IO devices placed in the sternum, humeral head, and proximal tibia using a fresh human cadaver model. METHODS Commercially available IO ...

BACKGROUND Chondrosarcoma arising from the sternum is extremely rare and is often untreatable. Removal of the sternum for malignant tumor results in large defects in bone and soft tissue, causing deformity and paradoxical movement of the chest wall and making subsequent repair of the thorax very important. We report a very rare patient with a chondrosarcoma of the sternum who underwent case che...

Study was undertaken to provide a reference for the gross anatomy of the sternum of emu as one of the ratite species and also to compare the structural differences with sternum of duck and turkey. The sternum from four adult emu, turkey and duck were collected and used for the present study. The sternum was a large unsegmented bone located on the antero-ventral aspect of the body cavity, bowl-s...

Pectus carinatum (PC) is a chest deformity caused by a disproportionate growth of the costal cartilages compared to the bony thoracic skeleton, pulling the sternum towards, which leads to its protrusion. There has been a growing interest on using the 'reversed Nuss' technique as a minimally invasive procedure for PC surgical correction. A corrective bar is introduced between the skin and the th...
