Abstract

Posterior vertebral column resection (PVCR) is a complex reconstructive procedure that helps reduce significantly severe spinal deformities, but it is also uncommon at Hospital for Traumatology and Orthopedics. A 14-year-old male patient developed severe kyphosis and scoliosis, he had multiple surgeries: hemivertebral resection (Egg shell method) and unilateral instrumentation in 2012. After that, he subsequently underwent adding screws in 2015 and removing all instruments in 2018.  He underwent a T12 PVCR and T4–L3 instrumented posterior spinal fusion. The patient had transient neurologic problems but recovered after a few days. The correction rate was 64.4% in coronal plane and 58.2% in sagittal plane. Six months postoperatively, correction was well maintained with appropriate alignment and balance without implant breakage. Our results suggest that PVCR with IOM support are safe and efficacious techniques for severe rigid kyphoscoliosis in the lumbar region associated with excellent correction rate. Surgeons need to have a thorough understanding of the spine anatomy, surgical indications and techniques, and clinical outcomes.
