We report the surgical treatment course of a 4-year-old girl with congenital scoliosis, diastematomyelia and double adjacent hemivertebrae. She had a lumbar curve with an apparent pelvic obliquity. Simultaneous excision of double segmented sequential hemivertebra at the L3-L4 level and fusion with shortsegment instrumentation was performed via a posterior approach. Intraoperative radiographs revealed satisfactory curve correction and 0 degrees pelvic obliquity. Following the excision of double adjacent hemi-vertebrae, three adjacent nerve roots were placed in one intervertebral foramen bilaterally. Nevertheless, no neurological deficit was developed, and the patient was able to ambulate with a brace at day one. Pelvic balance and deformity correction were maintained with no implant failure at the fifth year followup. Excision of two ipsilateral adjacent hemivertebra and short-segment posterior fusion performed via posterior-only approach simultaneously is an effective, safe, and less invasive technique for the treatment of the described case.
