Anterior dynamic scoliosis correction is an innovative non-fusion option in the treatment
of patients with severe adolescent scoliosis. Growth modulation and sometimes intraoperative
curve correction is achieved by convex insertion of segmental screws and a flexible
polyethylene cord. The present review analyses and discusses the current literature
and proposes a new treatment algorithm that is based on our own experience. Short
term results are published for approximately 100 patients from different institutions.
Fusion could be prevented in the vast majority of patients. Perioperative complication
rate is very low but a few cases of cord rupture and overcorrection are reported.
Anterior dynamic scoliosis correction has promising short term results but there is
a paucity of literature and optimal criteria for the best candidate has yet to be
defined.
