We study the bending of a thin plate, stiffened with a thin elastic layer, of thickness δ. We describe the complete construction of an asymptotic expansion with respect to δ of the solution of the Kirchhoff-Love model and give optimal estimates for the remainder. We identify approximate boundary conditions, which take into account the effect of the stiffener at various orders. Thanks to the too...

In years past, a rather voluminous literature has accumulated dealing with certain neurologic and circulatory deficits that occur in the upper extremities. Cervical rib syndrome, scalenus anticus syndrome, Naffziger syndrome, and scalenus neurocirculatory compression syndrome are among the names applied to the variable symptom complex found present in a small percentage of individuals with abno...

BACKGROUND Surgical management of fractured ribs with internal fixation is an increasingly accepted therapy. Concurrently, specific rib fixation prostheses are being developed which should improve results and minimise hardware and rib/splint construct failures. The Synthes titanium intramedullary splint lends itself to difficult to access areas such as posterior rib fractures and fractures unde...

IN the past seven years four cases of cough fracture with eight fractures were found at Killadeas Hospital and the Chest Clinic, Erne Hospital, Enniskillen. No previous record of cough fracture of a rib in Northern Ireland is known to the writer. Yet any patient with a history of cough followed by pleuritic pain may be suffering from one. Other conditions predisposing to fracture may also be pr...

OBJECTIVE To evaluate the utility of oblique chest views in the diagnosis of rib fractures when used as a routine part of the skeletal survey performed for possible physical abuse. METHODS Oblique chest views have been part of the routine skeletal survey protocol at Primary Children's Medical Center since October 2002. Dictated radiology reports since that time were reviewed, and all cases wi...

OBJECTIVE We hypothesized that lung injury and rib cage fracture quantification would be associated with adverse outcomes. SUBJECTS AND METHODS Consecutive admissions to a trauma center with Injury Severity Score ≥ 9, age 18-75, and blunt trauma. CT scans were reviewed to score rib and sternal fractures and lung infiltrates. Sternum and each anterior, lateral, and posterior rib fracture was s...

costochondral and rib grafts have long been used for reconstruction of lost condyle. donor site morbidity has less been under investigation and researched. pleural disruption pneumothorax and ugly scars are among the donor site complications. this study aims to determine the rate of pleural disruption following costochondral graft harvesting from the 4th to the 7th ribs of right and left ribs f...
