[Clinical application of TRAFIX internal fixation system in correction of scoliosis]
1Department of Orthopedic, Peking Union Medical College Hospital, Peking Union Medical College, Beijing 100730, China.
Objective:
To evaluate the results of TRAFIX internal fixation system in correction of adolescent scoliosis.
Methods:
From October 1997 to June 1999, 27 patients with idiopathic scoliosis received spinal instrumentation with TRAFIX system. Their average age was 14.2 years (from 11 to 21). Four patients of the 27 underwent anterior release, while 1 patient accepted revision approach. The average follow up time was 26 months (13-37 months).
Results:
The measurements for primary coronal deformity before and after surgery were 65 degrees (42 degrees-110 degrees) and 29.2 degrees (3 degrees-64 degrees) respectively. The average curve correction was 55.4%. The average fused segments were 11.5 vertebrae. The distance between the center of apex and C7 plumb line was 52.1 mm before operation (25-94 mm) and 28.5 mm after surgery (4-62 mm).
Conclusion:
The TRAFIX internal fixation system provides three-dimensional correction with refinement, convenient and reliable fixation.
