Posterior vs. anterior & posterior approach for severe scoliosis treatments — 5 observations

Researchers compared a combined anterior and posterior approach to a posterior approach for
severe scoliosis treatment, in a study published in Spine.

The study included patients with idiopathic scoliosis undergoing operations with Cotrel–
Dubousset hybrid instrumentation with pedicle screw and hooks. Thirty patients underwent the
two-stage surgery and 46 underwent posterior surgery.

Here are five observations:

1. Researchers did not find significant correction differences between the two-stage
surgery group with an average correction of 69 percent and the posterior group, with an average correction of 66

2. The study revealed hospitalization time was higher for the two-stage group compared to the
posterior group.

3. Additionally, surgery duration was significantly longer for the two-stage surgery group.

4. Researchers concluded the posterior approach and the two-stage approach are “equally
effective for operative treatment of severe idiopathic scoliosis in terms of regaining good balance,
achieving maximal possible correction with minimal complications, and good long-term clinical

5. Based on the two-stage group’s longer surgery duration and hospital stay, however, the
posterior approach may be the preferred treatment method for severe idiopathic scoliosis.
