STUDY DESIGN A retrospective analysis of 7 patients with traumatic rotatory atlanto-axial subluxation. OVERVIEW OF LITERATURE Cases of traumatic rotatory atlantoaxial subluxation in children are difficult to be stabilized. Surgical challenges include: narrow pedicles, medial vertebral arteries, vertebral artery anomalies, fractured pedicles or lateral masses, and fixed subluxation. The use of...

With the continuous development of the industrialization process, the countries all over the world gradually appeared lack of agricultural labor force and aging phenomenon, which was especially prominent in developed countries. However the agricultural robot with high operating efficiency, high qualities of work will play an increasingly important role in future agricultural production. Robot n...

This article would study batch and recursive methods that used in terrain navigation systems. Terrain navigation has a lot ofdisadvantages and so researchers have been studied on different method of aided navigation for many years. Therefore, more types of aided navigation systems were introduced with advantages and disadvantages in terms of practical and theoretical. One of the main ideas for ...

Cognitive impairments prevent older adults from using powered wheelchairs due to safety concerns, thus reducing their mobility and resulting in increased dependence on caregivers. An intelligent powered wheelchair is proposed to help restore mobility, while ensuring safety. Machine vision and learning techniques are described to help prevent collisions with obstacles, and provide reminders and ...

Background and Aim: Numerous efforts over the past century have been performed. Various innovation techniques are increasingly gaining attention and gradually established the foundation of recent significant developments in the world of neurosurgery, among which varied stereotactic neuro-navigation designs and other novel emerging systems are being quotidian developed. This narrative review ai...

The Pennsylvania Patient Safety Reporting System is a confidential, statewide Internet reporting system to which all Pennsylvania hospitals, outpatient-surgery facilities, and birthing centers, as well as some abortion facilities, must file information on medical errors. Safety Monitor is a column from Pennsylvania's Patient Safety Authority, the authority that informs nurses on issues that can...

C intraoperative navigation has evolved to become an integral part of spinal surgery (5,38,43). By rendering multiplanar three-dimensional (3-D) reconstruction in real-time, modern navigation techniques provide instant visualization of complex spinal anatomy and allow tracking of various surgical instruments within the operative field. Multiple studies have shown that navigation enhances the sa...

This paper presents a preliminary set of results on the design of a Sensor Fault Detection System (SFDS) for a smart wheelchair to prevent simples navigation sensor faults and hence to reduce the risk of safety hazards. The Structural Analysis technique is considered which uses graph theory to determine which redundancy exists in the sensory system and thus shows the possibility to detect and h...

Recently new location technologies have emerged that can be employed in modern advanced navigation systems. They can be employed to augment common satellite positioning techniques (GNSS) and dead reckoning as they offer different levels of positioning accuracies and performance. An integration of other technologies is especially required in indoor and outdoor-to-indoor environments. The paper g...

Future in-vehicle information systems may overload drivers, compromising driving safety and product usability. Suggestions of overload appear in (1) statistics from Japan, the United States, and Kuwait for mobile phone-related crashes, (2) statistics from Japan for navigation system-related crashes, and (3) human performance data. From most to least frequent, tasks associated with crashes were ...
