Abstract
Background: Vertebral column resection (VCR) has historically been recognized as the most efficacious corrective intervention for severe rigid spinal deformities. Nevertheless, advancements in preoperative optimization, staged corrective methodologies, osteotomies, and contemporary instrumentation have broadened the spectrum of therapeutic options available. The definitive role of VCR in the modern management of rigid congenital spinal deformities remains a topic of ongoing scholarly discourse. Methods: This study presents two illustrative cases of severe congenital spinal deformities that were addressed employing various surgical methodologies, alongside a comprehensive review of the current literature pertaining to VCR and less invasive alternatives, including halo-gravity traction (HGT), temporary internal distraction techniques, pedicle subtraction osteotomy (PSO), asymmetric pedicle subtraction osteotomy (APSO), and multi-rod constructs. Results: The cases elucidated herein underscore the necessity for treatment strategies to be tailored specifically to the characteristics of the deformity, its flexibility, the neurological risks involved, and the individual patient’s specific attributes. In one case, significant deformity correction achieved via preoperative HGT facilitated successful management through multilevel Ponte osteotomies and posterior spinal fusion, thereby obviating the need for VCR. In other patient suffering from severe rigid congenital kyphotic deformity with pronounced anterior column deficiencies, VCR was deemed essential to realize adequate correction and neural decompression. All patients exhibited substantial radiographic correction, enhancements in health-related quality-of-life metrics, diminished disability and pain, while maintaining correction without neurological complications or implant failure at the final follow-up evaluation. Conclusions: VCR continues to be a vital element within the surgical repertoire for the treatment of severe rigid spinal deformities; however, it should not be deemed obligatory in every instance. Diligent preoperative evaluation, staged correction methodologies, and less invasive osteotomy techniques may permit satisfactory correction while mitigating surgical morbidity in suitably selected patients. Treatment approaches should be customized, favoring the least invasive procedure capable of achieving safe and lasting correction whenever practicable.
