A representative case of spine-shortening osteotomy. (A) Preoperative lateral radiograph. (B) Preoperative sagittal T2-weighted magnetic resonance imaging (MRI) scan shows a low-placed conus medullaris and terminal filum connected with a subcutaneous lipomyelomeningocele at the S1–S2 level. (C) Postoperative lateral radiograph 3 years after surgery shows complete bone union and significant spine shortening. (D) Postoperative sagittal T2-weighted MRI scan obtained 1 year after surgery. The spinal cord tension was relieved after surgery as shown by preoperative MRI.
