INTRODUCTION Interposition grafts combined with anterior plating currently remain the gold standard for anterior cervical discectomy and fusion. The use of anterior plates increases fusion rates but may be associated with higher rates of postoperative dysphagia. The aim of the current study was to determine the clinical and radiological outcomes following(More)
OBJECT In this paper the authors' goal was to compare the accuracy of computer-navigated pedicle screw insertion with nonnavigated techniques in the published literature. METHODS The authors performed a systematic literature review using the National Center for Biotechnology Information Database (PubMed/MEDLINE) using the Medical Subject Headings (MeSH)(More)
OBJECT Anterior cervical plating decreases the risk of pseudarthrosis following anterior cervical discectomy and fusion (ACDF). Dysphagia is a common complication of ACDF, with the anterior plate implicated as a potential contributor. A zero-profile, stand-alone polyetheretherketone (PEEK) interbody spacer has been postulated to minimize soft-tissue(More)
OBJECT Three-dimensional spinal navigation increases screw accuracy, but its implementation in clinical practice has been difficult, mainly because of surgeons' concerns about increased operative times, disturbance of workflow, and safety. The authors present a custom-designed navigated guide that addresses some of these concerns by allowing for drilling,(More)
BACKGROUND Radiculopathy caused by foraminal nerve root compression is a common pathology in the lumbar spine. Surgical decompression via a conventional open foraminotomy is the treatment of choice when surgery is indicated. Minimally invasive tubular foraminotomy through a contralateral approach is a potentially effective surgical alternative. OBJECTIVE(More)
Several studies have suggested that the iliotibial (IT) band plays a role in knee laxity and that it may affect the magnitude of the pivot shift observed. However, the extent of the role played by the IT band, as well as its mechanism of action, is not currently known. This cadaveric study aimed to quantify the effect of the IT band and the hip abduction(More)
STUDY DESIGN Animal experimental study. OBJECTIVE To evaluate a novel quantitative imaging technique for assessing disc degeneration. SUMMARY OF BACKGROUND DATA T2-relaxation time (T2-RT) measurements have been used to assess disc degeneration quanti-tatively. T2 values correlate with the water content of intervertebral disc tissue and thereby allow for(More)
Spinal surgery under Eastern-African circumstances is technically demanding and associated with significant complications, such as blood loss, infection, and wound breakdown. We report a spinal trauma case that was performed using minimally invasive surgery (MIS) and navigation, and hypothesize that these newer techniques may enable surgeons to perform(More)
PURPOSE There are a number of factors responsible for the longevity of unicompartmental knee replacements (UKR). These include the magnitude of postoperative alignment and the type of material used. The effect of component design and material on postoperative alignment, however, has not been explored. MATERIALS AND METHODS We retrospectively reviewed 89(More)
30-day mortality was noted to be 17.9% in the , 150 mm Hg target group compared to 11.1% in the, 180 mmHg group (P1⁄4 .40) (Table 1). The morbidity rate as noted by the NIHSS score, 2 hours and 24 hours after randomization, was not significantly different among target groups (Table 1). Similar results were noted on the 90-day BI scores (P 1⁄4 .51) and(More)
