Minimum 10 Year Radiographic Results after Selective Thoracic Fusion for AIS Patients with Lenke Type 1C Curves
Information provided by
Poster from the 2006 SRS Annual Meeting
Introduction: Selective anterior thoracic fusion can be performed
in adolescent idiopathic scoliosis (AIS) even with a widely deviated compensatory
lumbar curve. Nevertheless, long-term outcome and whether treatment is better
with fusion of both curves remains unclear.
Material and Methods: 15 patients with Lenke type 1C were operated between 1991 and 1994 (mean age 15.4 y, all patients had preop traction films). Radiographs were retrospectively evaluated with a minimum follow up of 10 years.
Results: Mean preop thoracic curve 57.1 ± 12.9 , lumbar curve 41.5 ± 8.8 . Mean thoracic curve at latest follow up 26.2 ± 12.1 , lumbar curve 22.1 ± 8.0 (mean of 55 % thoracic and 46 % spontaneous lumbar correction). No reoperations, no distal extension of the fusion.
Conclusion: Good radiographic results in type 1C curves can be achieved with a selective anterior thoracic fusion over a long-term period. Traction films help to carefully select the appropriate patients.
