Thus vertebral arch views (pillar views) needs to be obtained if there is evidence to counsel 
hyperextension as the mechanism of harm. Corrections of a 
extreme flexion deformity and slight hyperextension of the cervical spine was produced safely at the 
level between the seventh cervical vertebra and first thoracic vertebra in a girl, 
forty-four years outdated. A complete of 1,321 patients underwent spine 
surgeries at our institute from January 1, 2005 to December 31,
2005. Among them, there were 562 patients (42.5%) youthful than 50 years old, and 759 
patients (57.6%) older than 50 years previous.
We strongly recommend an analysis for osteoporosis and publish-operative therapy 
for osteoporosis in patients over 50 years previous, especially for feminine patients.
Among the many female patients, there have been 134 (41.4%) with osteopenia and 166 
(51.3%) with osteoporosis. The incidence of osteoporosis was greater in feminine patients and 
significantly elevated with rising age. The patients over 50 12 months-outdated 
who want spine operation have osteoporosis usually.
