Fractures of the first rib are uncommon in athletes and present a different clinical entity from traumatic first rib fracture associated with high energy thoracic trauma. These fractures are stress induced and precipitated by chronic muscular forces acting on the first rib. Typically they heal with conservative treatment. This report describes a fracture of the first rib in a tennis player that...

OBJECTIVES Despite recommendations that central obesity assessment should be employed as a marker of cardiometabolic health, no consensus exists regarding measurement protocol. This study examined a range of anthropometric variables and their relationships with cardiometabolic features and type 2 diabetes in order to ascertain whether measurement site influences discriminatory accuracy. In part...

PURPOSE To provide the anatomical knowledge necessary to draw biopsy routes by using an anterior approach above and below the first rib to avoid internal mammary vessel damage. MATERIALS AND METHODS The anatomy of internal mammary vessels above and below the first rib was assessed by thin-section computed tomography (CT) analysis of 61 adults. The visibility of the internal mammary vessels, t...

To our knowledge, the clinical characteristics of traumatic vertebral fractures and concomitant fractures of the rib (TVF-RF) have not been described in previous studies.To investigate the clinical characteristics of patients managed for TVF-RF. A retrospective study of 3142 patients who presented with traumatic vertebral fractures was performed. Two hundred twenty-six patients (7.2%) suffered ...

Background: Variations in the number of ribs and vertebrae have been noted in other wise normal looking people with some having supernumerary while others subnumerary. Sternal variations and anomalies though have not been as widely documented. These are two cases with one having a combination of sternal anomalies, supernumerary thoracic vertebrae and ribs and subnumerary lumbar vertebrae while ...

Introduction: The elastic modulus of human rib bone derived from tensile coupon tests (13.9GPa) could be too high for applications in Finite Element (FE) modeling of the human thorax, as the homogenous elements lack the microstructure of typical rib bone. In this study MicroCT scans of ribs from three cadavers were used to determine homogenized elastic moduli of ribs that could be applied to so...

The stabilizing effect of the rib cage on the human thoracic spine is still not sufficiently analyzed. For a better understanding of this effect as well as the calibration and validation of numerical models of the thoracic spine, experimental biomechanics data is required. This study aimed to determine (1) the stabilizing effect of the single rib cage structures on the human thoracic spine as w...

The pressure acting on the part of the Rib Cage that is apposed to the costal surface of the lung is quite different from that acting on the part apposed to the diaphragm. The non uniformity of pressure distribution led Agostoni and D’Angelo (1985) to suggest that the rib cage could be usefully regarded as consisting of two compartments mechanically coupled to each other (Agostoni & D’Angelo, 1...

This paper presents an automated and comprehensive system for eliminating rib shadows in chest radiographs, which integrates lung field identification, rib segmentation, rib intensity estimation, and suppression. We designed a region of interest (ROI)-based method to estimate a suitable initial lung boundary for active shape model (ASM) deformation by determining the translation and scaling par...
