ABSTRACT

Congenital scoliosis is the most common congenial deformity, usually caused by one or more hemivertebra. There is strong progressive potential of the deformity in about 50% of scoliosis patients with this aetiology. The objective of our study was to report the results of the technique we use in the correction of congenital scoliosis caused by a hemivertebra and to determine the correction percentage of the deformity and observe the evolution in time of our patients. We selected a small study group of patients from our hospital, with complete medical records, with at least one year follow-up after the surgery, no other surgeries on that site and operated by the same senior surgeon. The technique we describe consists of a single approach procedure using transpedicular enucleation of the vertebra, removal of the pedicle, correction of the deformity and posterior fusion using segmentary fixation. The patient's mean age at the time of surgery was 14.78(±2.09) years showing a progressive curve in the last year or a major deformity requiring surgical treatment; the mean scoliotic deformity was 62.35° (±12.91) before surgery and 26.64° (±11.57) after the operation; with a mean correction of 58.7(±12.25)% of the initial curve. At the latest follow-up the mean curve was 28° (±11.78), with no significant difference to the immediate postoperative measurement. Transpedicular enucleation associated with posterior spinal fusion is a safe and effective method for one-stage correction of a spinal deformity caused by the presence of a hemivertebra.
