STUDY DESIGN Retrospective analysis. OBJECTIVE To demonstrate the effectiveness of hook-rod constructs in closing thoracic osteotomies safely and effectively. SUMMARY OF BACKGROUND DATA The outcomes of hook-rod instrumentation in osteotomies for the correction of kyphosis at the lumbar region of the spine have been described. Little literature exists on(More)
STUDY DESIGN Retrospective review of prospectively collected data on the neuromonitoring changes recorded during a consecutive series of cord level 3-column posterior spinal osteotomies for the correction of rigid pediatric spinal deformities in children between 2005 and 2012. OBJECTIVE To review the neuromonitoring changes observed during the performance(More)
This paper evaluates the relation between Alcohol Withdrawal Syndrome tremors in the left and right hands of patients. By analyzing 122 recordings from 61 patients in emergency departments, we found a weak relationship between the left and right hand tremor frequencies (correlation coefficient of 0.63). We found a much stronger relationship between the(More)
OBJECTIVES It is estimated that 15%-25% of patients with a mild traumatic brain injury (MTBI) diagnosed in the emergency department (ED) will develop postconcussive syndrome. The objective of this study was to determine if patients randomized to graduated return to usual activity discharge instructions had a decrease in their Post-Concussion Symptom Score(More)
STUDY DESIGN A retrospective analysis. OBJECTIVE The purpose of this study was to determine whether the deformity angular ratio (DAR) can reliably assess the neurological risks of patients undergoing deformity correction. SUMMARY OF BACKGROUND DATA Identifying high-risk patients and procedures can help ensure that appropriate measures are taken to(More)
To report the use of a posterior based ‘fusion mass screw’ (FMS) as a primary or salvage fixation point in a revision spinal deformity following a previous posterior spinal fusion (PSF). Our experience of this technique in a case report and the clinical and radiological results are reported. To describe the technique and uses of the FMS as a primary/salvage(More)
OBJECTIVE To review and expose the occurrences of tension pneumothorax as a result of pleural tear during posterior spinal surgery. METHODS Intraoperative reports were retrospectively reviewed for 2 patients who underwent posterior spinal fusion and experienced pleural tear and subsequent tension pneumothorax. Surgical decisions for recognition and(More)
In this paper, we have introduced a novel method to extract involuntary tremor movement activity in patients with Alcohol Withdrawal Syndrome (AWS). Using the Empirical Mode Decomposition (EMD), we show that the variations of energy of the tremor and voluntary activity can be distinguished in different Intrinsic Mode Functions (IMF) of the recorded tremor(More)
STUDY DESIGN Retrospective review and analysis of lateral long cassette radiographs. OBJECTIVE The purpose of this paper is to assess whether certain radiographic features routinely seen on lumbar radiographs can predict a structural thoracic deformity. SUMMARY OF BACKGROUND DATA Obtaining proper sagittal alignment is an essential factor contributing to(More)
