iontophoresis of epinephrine for assessment of neuromuscular junction response is a new technique that can improve diagnose of neuromuscular dysfunction. the purpose of this study was to investigate the effects of iontophoresis of epinephrine on neuromuscular junction response. iontophoresis of epinephrine solution (1mg/ml), sodium chloride, calcium gluconate, epinephrine with sodium chloride a...

OBJECTIVE The purpose of this study was to compare the reliability of the lateral fluoroscopic view and several contralateral oblique (CLO) views at different angles in visualizing and accurately predicting the position of the needle tip at the point of access in the posterior cervical and cervicothoracic epidural space. DESIGN After the epidural space was accessed but before confirmation wit...

Background: Fractures of the cervical spine are a frequent injury in the elderly with potentially devastating consequences. In most cases surgical therapy is required, in hyperextension fractures most often with anterior cervical fusion. Methods: We report a case of an 88-year old patient with a fracture of C7 (AO-type B3) who underwent anterior cervical fusion with manubrium sterni osteotomy f...

Spinal deformities can result in increasing thoracic kyphosis or loss of lumbar lordosis, leading to imbalance in the sagittal plane. Such deformities can be functionally and psychologically debilitating. The Smith-Petersen osteotomy can achieve approximately 10 degrees of correction in the sagittal plane at each spinal level at which it is performed. This osteotomy is beneficial for patients w...

Respiratory stridor developed rapidly during an interscalene brachial plexus block for shoulder arthroscopy in an obese woman. Extensive cervicothoracic edema due to tissue diffusion of the arthroscopic fluid was suspected. The outcome of patient after conservative management was satisfactory. We give a brief review of how this complication develops, the ultrasound findings, and briefly discuss...

STUDY DESIGN Prospective clinical study with postoperative radiologic control of pedicle screw placement in the cervical spine. OBJECTIVES To evaluate whether cervical pedicle screws can be placed safely in a conventional technique when using cannulated screws and separate stab incisions. Also, to evaluate if accuracy and safety of pedicle screw placement can be improved using a computer-assi...
