Received, October 28, 2004. Accepted, March 9, 2005. THE FAR-LATERAL APPROACH is an extension of the standard suboccipital approach, designed to maximize exposure of the lateroventral craniocervical junction. Following a basic principle of cranial base surgery, the angle of view is increased by bone removal. Bone removal involves the most lateral part of the inferior occipital squama and the po...

BACKGROUND Several scoring systems for cervical disc and facet joint degeneration, using radiography or computed tomography, have been developed and tested for reliability. However, definitions of disc height and facet joint space narrowing vary. To our knowledge, no study has reported quantitative data for normal radiologic values of the cervical spine in the Korean population. The purpose of ...

A 44-year-old man presented after 3 weeks of progressively worsening atraumatic onset pain in the right anteromedial thigh. The pain was sharp and radiated to the anteromedial shin and medial foot. The patient had no associated weakness, numbness, or bowel/bladder dysfunction. Nonsteroidal anti-inflammatory, pain, and neuropathic-relieving drugs had limited effect. He underwent interlaminar inj...

OBJECTIVE The object of this study was to evaluate the clinical and radiological outcomes of minimally invasive lateral lumbar interbody fusion. METHODS This study included 30 patients who underwent minimally invasive lateral lumbar interbody fusion at our hospital between May 2011 and February 2012 for the following diagnoses: degenerative disc disease, adjacent-segment degeneration, degener...

provided the original work is properly cited. CC Nucleoplasty is a minimally invasive spine intervention technique that uses controlled ablation, known as coblation to decompress the protruded intervertebral disc. Due to its short history and narrow indications, there is limited evidence concerning the efficacy and clinical outcome of cervical nucleoplasty. However, recent clinical experiences ...

STUDY DESIGN Nondestructive displacement-controlled dynamic testing of cadaver material, with repeated measures design and randomized sequence of tests. OBJECTIVE To determine whether the frequency-dependent changes in disc stiffness and phase angle between load and displacement differ between the 6 principal directions of displacement, and whether these differences are greater in deformation...

OBJECT Cervical total disc replacement has emerged as a surgical option to preserve motion and potentially avoid adjacent-segment disease after anterior cervical discectomy and fusion. Recently, much attention has been directed at the ability of a given device to maintain and/or restore normal segmental alignment. Nonphysiological disc and segmental angulation could result in increased stresses...
