Nonfusion method in thoracolumbar and lumbar spinal fractures.

摘要: Study Design. A retrospective study of surgically managed patients. Objective. To evaluate the results posterior stabilization thoracolumbar fracture using nonfusion method followed by removal metal implants within an appropriate period. Changes in sagittal alignment and restoration segmental motion were also investigated. Summary Background Data. Posterior fusion a transpedicular screw system remains treatment choice for management lumbar fractures. However, methods result permanent loss motion. If both stability could be achieved, functional would improve considerably. Methods. Twenty-three patients under 40 years age (mean, 28.0 years) with or spine fractures this method. Implants removed at mean 9.7 months after initial fixation, observed more than 18 months. Sagittal alignments fixed segments, heights vertebral bodies, recovered ranges flexion/ extension, right-left bending view measured radiologically. Clinical aspects, such as gross deformities abilities, Results. Heights fractured bodies well maintained final follow-up. Initial angle was 17.2° kyphosis, which became 2.8° lordosis fixation This 1.7° kyphosis just before implant removal, 2.4° showed 5.9° Mean 14.2° plane 13.1° coronal Most satisfied appearance outcome. Conclusion. The described appears to effective achieving favorable regaining motions segments. present suggests that is one most managing fractures, especially young active people.
