STUDY DESIGN An in vitro biomechanical study of C1-C2 posterior fusion techniques was conducted using a cadaveric model. OBJECTIVE To investigate and compare the acute stability afforded by a novel rod-based construct that uses direct polyaxial screw fixation to C1 and C2 with contemporary transarticular screw and wire techniques. SUMMARY AND BACKGROUND(More)
BACKGROUND Craniovertebral arthrodesis in the upper cervical spine is challenging because of the high degree of mobility afforded by this region. A novel method for achieving atlantoaxial fixation with use of polyaxial screws inserted bilaterally into the lateral masses of C1 and transpedicularly into C2 with longitudinal rod connection has recently been(More)
Studies comparing the relative merits of microdiscectomy and standard discectomy report conflicting results, depending on the outcome measure of interest. Most trials are small, and few have employed validated, multidimensional patient-orientated outcome measures, considered essential in outcomes research. In the present study, data were collected(More)
OBJECT The contemporary assessment of spine surgical outcome primarily relies on patient-centered reports of symptoms and function. Such measures are considered to reduce bias compared with traditional surgeon-based outcome ratings. This study examined the agreement between patients' and surgeons' ratings of outcome 1 year after spine surgery. METHODS The(More)
