Study Design:
Retrospective analysis.
Objective:
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.
Summary Of Background Data:
VCR allows for correction of severe, rigid spinal deformity. This technique has not been previously reported in children with neuromuscular disorders.
Methods:
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).
Results:
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.
Conclusion:
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.

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...

Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
