Vertebrectomy and instrumentation only via the posterior approach has been increasingly used in sagittal, frontal plane and combined
deformities. The aim of this retrospective study is to evaluate the clinical and radiological results of hemivertebrectomy and instrumentation only via the posterior approach in congenital spinal
deformities. Between 1998 and 2003, we performed hemivertebrectomy and interbody fusion using posterior instrumentation with
titanium mesh cage via the posterior approach in 19 patients (three
scoliosis, five
kyphosis and 11 kyphoscoliosis). The age of the patients ranged from 2 to 22 years and they all underwent hemivertebrectomy (at thoracic level in six patients, at thoracolumbar level in eight patients and at lumbar level in five patients). A
titanium mesh cage was used for anterior column support and interbody fusion in patients who had residual anterior gap preventing bone-to-bone contact. Correction and stabilization were achieved by posterior polyaxial
pedicle screws. Follow-up was an average of 4.6 years (range: 2-7 years). We did not confront any loss of correction,
pseudoarthrosis, and
titanium mesh cage collapse or implant failure. Hemivertebrectomy and instrumentation via the posterior approach is a good one-stage surgical treatment option that can be used to avoid the surgical
trauma and morbidity related to anterior surgery. It is a technically demanding
surgical procedure, however, requiring extreme care and experience in spine surgery.
