10-Year Survival Rate for Adult Primary Scoliosis Surgery Assessed

(HealthDay News) — In adult middle-aged patients undergoing primary scoliosis surgery, the 10-year survival rate is 61%, according to a study published in the August 1 issue of The Spine Journal.

Felisa Sánchez-Mariscal, MD, PhD, from the University Hospital of Getafe in Madrid, and colleagues retrospectively analyzed survival among a cohort of 59 consecutive adult patients (median age, 42 years). Participants had had a primary surgery for scoliosis (idiopathic or degenerative curves with median preoperative frontal Cobb angle of 59 degrees), with >4 motion levels fused. The median follow-up was 8.5 years.

The researchers found that survival was 89.8% at one year, 79.4% at two years, 73.4% at three years, 64% at five years, and 60.9% at 10 years. Over one-third of patients (21) underwent revision surgery. Reasons cited for reoperation were painful/prominent implants, adjacent-segment degeneration, and infection. Higher revision rates were seen among American Society of Anesthesiologists Type II patients, those with a double surgical approach, and those with preoperative thoracic kyphosis.

"Risk factors identified for reoperation included patients with higher morbidity, double surgical approach, and preoperative thoracic hyperkyphosis," the authors write.
