Females with scoliosis had higher rates and RR of epidural anesthesia. Those with scoliosis treated nonoperatively had a significantly lower rate of CS compared to non-IS females. Females with scoliosis treated surgically, however, had a lower RR of receiving epidural anesthesia, irrespective of fusion level.Females with scoliosis were significantly more likely to receive epidural anesthesia at delivery compared to females without scoliosis.Rates and relative risk of Cesarean delivery were not significantly lower among women with scoliosis, but females treated non-operatively for scoliosis had a significantly lower CS rate than those without scoliosis.Females treated with spine fusion for scoliosis were far less likely to receive epidural anesthesia than both females without scoliosis and females with scoliosis treated non-operatively.Amongst patients who underwent spine fusion as children, those with proximal fusions (L3 and proximal) did not have significantly different rates or relative risk of epidural anesthesia or Cesarean delivery compared to those with distal fusion (to L4 or L5 ).
