Background:
Internal distraction rods have been described as an alternative to halo gravity traction for the treatment of severe scoliosis. Distraction rods can be challenging to use in patients with existing fusion masses. The authors report an internal distraction, construct-to-construct rod technique using multiple-hook fixation in a patient with a sharply angulated cervicothoracic scoliosis fusion mass.
Observations:
A 12-year-old female with previously diagnosed congenital scoliosis who had undergone cervical fusion in situ at age 2 presented to the clinic with shortness of breath exacerbated by increased levels of activity. Standing anteroposterior and lateral scoliosis radiographs revealed a left >150° cervicothoracic curve, right 140° thoracolumbar curve, and left 28° lumbosacral fractional curve with pelvic obliquity. The authors indicated this patient for a 3-stage all-posterior approach for spinal fusion and deformity correction. In the final fusion surgery, the authors set up a construct-to-construct internal distraction configuration connecting the left hemipelvis to the cervicothoracic fusion mass to aid in deformity correction.
Lessons:
A construct-to-construct internal distraction rod technique connecting a fusion mass to the pelvis can assist with curve correction in severe scoliosis.
