Study Design Large cohort study. Purpose To clarify spinal sagittal alignment and health-related quality of life (HRQOL) according to sex in volunteers aged >50 years with cervical deformity (CD). Overview of Literature Adult spinal deformities, especially those associated with lumbosacral lesions, are more frequent in females; however, CD is observed to a greater extent in males. Methods...

Ossification of the posterior longitudinal ligament is a common cause of cervical myelopathy, and controversy remains regarding surgical options. Between January 2004 and December 2007, a total of 164 patients with ossification of the posterior longitudinal ligament in the cervical spine who underwent surgical treatment at the authors' institution were included in this study. The choice of surg...

OBJECTIVE Anterior cervical discectomy and fusion (ACDF) is a choice of surgical procedure for cervical degenerative diseases associated with radiculopathy or myelopathy. However, the patients undergoing ACDF still have problems. The purpose of the present study is to evaluate the radiologic results of 3 different methods in single-level ACDF. METHODS We conducted a retrospective collection o...

The purpose of this study was to evaluate the results of treatment of symptomatic cervical disc herniation using interbody cages and anterior plate fixation. Fifteen patients were studied retrospectively. An MRI study of the cervical spine was performed preoperatively in all patients. The levels involved were C5-C6 in 9 cases, C6-C7 in 4 and C3-C4 in 1, while 1 patient had disc disease at the C...

Anterior subluxation (hyperflexion sprain) is localized, purely ligamentous disruption of the cervical spine caused by a limited flexion force. When associated with a simple wedge fraction, also a flexion injury, anterior subluxation may be the more significant lesion. Radiographically, anterior subluxation is characterised by (1) a localized kyphotic angulation at the level of injury; (2) ante...

Fifteen patients with ankylosing spondylitis who had developed a severe flexion deformity of the cervical spine which restricted their field of vision to their feet, were treated by an extension osteotomy at the C7/T1 level. The operation was performed under general anaesthesia with the patient in the prone position and wearing a halo-jacket. Three had internal fixation using a Luque rectangle ...
