To determine, in pediatric patients with neuromuscular deformity undergoing vertebral column resection (VCR), the (1) characteristics of the surgery performed; (2) amount of pelvic obliquity restoration, and coronal and sagittal correction achieved; (3) associated blood loss and complications; and (4) extent to which curve type and VCR approach influenced correction, blood loss, and complications.
VCR allows for correction of severe, rigid spinal deformity. This technique has not been previously reported in children with neuromuscular disorders.
We retrospectively reviewed the records of 23 children with neuromuscular disorders (mean age, 15 years) and spinal deformities (severe scoliosis, 9; global kyphosis or angular kyphosis, 4; kyphoscoliosis, 10) who underwent VCR. The Student t test was used to compare correction differences (statistical significance, P < 0.05).
A mean 1.5 vertebrae (27 thoracic and 6 lumbar) were resected per patient. Significant corrections were achieved in pelvic obliquity (11°, from 19° ± 13° to 8° ± 7°), in major coronal curve (56°, from 94° ± 36° to 38° ± 20°), and in major sagittal curve (46°, from 86° ± 37° to 40° ± 19°). There was no difference in correction between various curve types. VCR was associated with substantial blood loss (mean, 76% [estimated blood loss per total blood volume]), which correlated with patient weight and operating time. Overall, 6 patients experienced major complications: spinal cord injury, pleural effusion requiring chest tube insertion, pneumonia, pancreatitis, deep wound infection, and prominent implant requiring revision surgery. There were no deaths or permanent neurological injuries.
VCR achieved significant pelvic obliquity restoration and coronal and sagittal correction in children with neuromuscular disorders and severe, rigid spinal deformity. However, this challenging procedure involves the potential for major complications.
Vertebral column resection is a challenging procedure that can be effectively used to treat severe, rigid spinal deformities in children with neuromuscular conditions. Although it is associated with potential severe complications, it allows appropriate spinal shortening and significant coordinated correction of coronal curve, sagittal curve, and pelvic obliquity.
