[Results of treatment of progressive scoliosis with SMA staples].

Anterior vertebral body stapling is a new minimally invasive technique to correct scoliotic deformities without fusion. In the literature only preliminary reports with short follow-up periods are available. A total of six patients with a minimum follow-up of 2 years were available for examination. Of the six patients four demonstrated progression of scoliosis in spite of vertebral body stapling. All had curves of more than 35 degrees at the time of surgery, while two patients with less extensive curves below 35 degrees did not show signs of progression. Major complications were not observed. Vertebral body stapling for curves more than 35 degrees does not seem to be indicated and careful patient selection for stapling may be indicated for curves less than 35 degrees . A more general use of this technique is not recommended at this time.
