STUDY DESIGN This study defined the projection point of the thoracic pedicles on their posterior aspect and its relation to a reliable landmark. It also reported pedicle dimensions based on 43 thoracic spines. OBJECTIVES To determine the projection point of the pedicle axis on the posterior aspect of the thoracic spine, quantitatively describe relations(More)
Eighteen adult dry-bone spine specimens were used in conjunction with computer analysis to determine the average axial spinal canal area at the levels of C6, C7, and T1 after different degrees of anterior translation of the cephalad vertebra. Simulating a distractive flexion injury, the cephalad vertebra was anteriorly displaced on the caudal vertebra at(More)
Hydatid disease is a zoonosis caused by Echinococcus granulosus . Infected dogs release eggs through their feces and the eggs infect humans through food and water. The most common locations of hydatid cysts are the liver and lungs, but primary mediastinal involvement, though rare, can be encountered. We report on a 16-year-old female with a primary(More)
Pulmonary artery aneurysms (PAA) are rare. To date there are no cases in the literature describing formation secondary to oesophageal perforation. We present an unusual case of ruptured inflammatory segmental PAA. A patient with oesophageal squamous cell cancer presented with shortness of breath and sepsis following endoscopic dilatation of an oesophageal(More)
BACKGROUND Arterial blood gas (ABG) analysis is routinely performed for sick patients but is fraught with complications, is painful, and is technically demanding. OBJECTIVE To ascertain agreement between the arterial and peripheral venous measurement of pH, pCO(2), pO(2), and bicarbonate levels in sick patients with cardiopulmonary disorders in the valley(More)
Forty-seven dry thoracic specimens from T-3 to T-12 (470 thoracic vertebrae) were used to measure the dimensions of the vertebral body of the thoracic spine and to determine the relationship of the posterior angulation of screw placement to the spinal canal from different entrance points. Statistically significant differences in dimensions of male and(More)
