Surgery for AIS may yield positive long-term outcomes

MINNEAPOLIS — Surgery to treat patients with adolescent idiopathic scoliosis resulted in long-term improvement in main coronal angle, coronal balance, scoliometer readings and other health outcomes, according to a presenter, here.
At the Scoliosis Research Society Annual Meeting, Daniel J. Sucato, MD, MS, said at
10 years after surgery, patients operated on for adolescent idiopathic scoliosis (AIS) reported solid improvements in Scoliosis Research Society-30 (SRS-30) Scores for appearance and patient satisfaction.
“There was mild loss in coronal and sagittal plane parameters from 2 years to 10 years, but they were seen without loss of pulmonary function,” Sucato said.
Seventy-two patients included in the study were available for 10-year follow up. At that time the patients’ average coronal Cobb angle improved from 59° to 29.7°. Coronal balance improved from 1.5 cm to 1 cm and the scoliometer reading improved from 13.5° to 8.3°.
Patients also reported high SRS-30 Scores for both appearance and satisfaction. Their improvement in coronal balance correlated to improvements in both subscales of the SRS-30 Score (P < .05), according to Sucato.
However, 20 patients reported pain on a fairly consistent basis at follow-up and 5 patients reported they underwent a repeat operation for infection, 2 patients were reoperated for prominent implants and 1 patient was reoperated for a painful implant during the long-term follow-up, he said. – by Robert Linnehan
