Thirty-six years experience of cervical extension osteotomy in ankylosing spondylitis: techniques and outcomes.

Study Design: A retrospective review of the cervical extension osteotomy in the past 36 years for the treatment of flexion deformity of patients with ankylosing spondylitis was conducted.

Objectives: To review the conventional and current surgical techniques of cervical extension osteotomy in ankylosing spondylitis and to evaluate the clinical outcomes.

Summary Of Background Data: Cervical osteotomy is a challenging procedure in the correction of flexion deformity in ankylosing spondylitis.

Vertebral tumors: surgical versus nonsurgical treatment.

Unlabelled: The treatment of spinal tumors represents a challenge to spine care professionals. Fortunately, the incidence of new cases of primary malignant bone tumors is lower compared with that of other tumors. In the United States approximately 2000 malignant bone tumors of 7000 new sarcomas are diagnosed each year.

Value of magnetic resonance imaging and discography in determining the level of cervical discectomy and fusion.

Study Design: The correlation between magnetic resonance imaging and discography of the cervical spine in degenerative disc disease was studied. In addition, the results of cervical discectomy and fusion were evaluated.

Objectives: To compare the value of cervical magnetic resonance imaging versus discography in selecting the level for discectomy and fusion and to evaluate the surgical outcome.

Active range of motion utilized in the cervical spine to perform daily functional tasks.

This was a descriptive study to examine active range of motion required in the cervical spine during functional tasks of daily living. The objective of this study was to determine the mean active range of motion of the cervical spine required to perform 13 daily functional tasks. Previous research has examined the absolute ranges of cervical motion for women and men 20-60 years of age; however, no previous study has determined the amount and type of motion that is required for routine activities of daily living.
