BACKGROUND Placement of thoracic pedicle screws is a technically demanding procedure. The risk of thoracic pedicle breaches range from 6.5 to 41%. Current image guidance systems consist of computer based systems utilizing preoperative CT scans or 2D/3D intraoperative fluoroscopy. OBJECTIVE The aim of this prospective study was to evaluate the clinical(More)
The objective of the paper is to propose a context aware mobile service deployment model to deliver the needed information to the farmers in planning their agricultural activities. The application developed based on this model utilizes the GSM networking of mobile devices to bring the details to the farmers using location awareness features. A context aware(More)
OBJECT Commercially available, preformed patient-specific cranioplasty implants are anatomically accurate but costly. Acrylic bone cement is a commonly used alternative. However, the manual shaping of the bone cement is difficult and may not lead to a satisfactory implant in some cases. The object of this study was to determine the feasibility of(More)
Subdural empyema is a rare but serious intracranial infection that warrants prompt management to reduce morbidity and avoid mortality. However, clinical and radiologic features may be subtle or ambivalent. Thus a diagnosis of subdural empyema should not be discounted, especially in a patient with a history of head trauma. Treatment consists of surgery to(More)
Modern image-guided spinal navigation employs high-quality intra-operative three dimensional (3D) images to improve the accuracy of spinal surgery. This study aimed to assess the accuracy of thoraco-lumbar pedicle screw insertion using the O-arm (Breakaway Imaging, LLC, Littleton, MA, USA) 3D imaging system. Ninety-two patients underwent insertion of(More)
Soft tissue chondromas are rare, benign extra-skeletal tumours of cartilaginous origin, which may rarely occur within the spinal canal. We report a patient who presented with left lumbar radiculopathy, and a peripherally-enhancing dumbbell shaped soft tissue mass involving both the intraspinal and extraspinal compartments on MRI. This was misdiagnosed as a(More)
OBJECTIVE To assess the feasibility and potential utility of intraoperative computed tomographic angiography (iCTA) in identifying unexpected residual aneurysms and major cerebral artery occlusion after cerebral aneurysm surgery. METHODS We prospectively studied 6 consecutive patients with ruptured anterior circulation aneurysms who underwent craniotomy(More)
