Abstract:

BACKGROUND: Patients with ankylosing spondylitis kyphosis deformity may be treated with single segment or two segment pedicle screw internal fixation according to the severity of deformity, and can obtain a good orthopedic effect.
OBJECTIVE: To multi-level explore and analyze the clinical application results and literatures on the effect of pedicle screw internal fixation on the treatment of ankylosing spondylitis kyphosis deformity.
METHODS: Sixteen clinical cases with ankylosing spondylitis kyphosis deformity treated with pedicle screw internal fixation were selected from the 306 Hospital of Chinese PLA for the analysis. A computer-based search was performed in CNKI database from 2002 to 2011 for the literatures on the effect of pedicle screw internal fixation on the treatment of ankylosing spondylitis kyphosis deformity. The key words were “pedicle screw, ankylosing spondylitis, kyphosis”. A total of 48 literatures were screened out and the data characteristics were in-depth analyzed.
RESULTS AND CONCLUSION: Ankylosing spondylitis is a kind of chronic diseases and has the characteristics of violation of the central axis of the spine joint, and in the advanced period, it often associates with thoracic or thoracolumbar ankylosing spondylitis kyphosis deformity. The patient is often unable to head-up after thoracic spine flexion increasing, and more serious, the lower ribs will squeeze internal organs and lead to cardiopulmonary dysfunct, which may affect the daily life and the aesthetics. Spinal osteotomy combined with pedicle screw internal fixation orthopedic treatment can achieve good results.
