INTRODUCTION: An unipedicular vertebral body stenting technique, termed 'central stentoplasty', was developed at our institution. With this technique, a single vertebral body stent was deployed percutaneously in the midline of the vertebral body using cone-beam computed tomography (CBCT) guidance.
METHODS: From September 2013 to July 2015, forty-four patients with fifty-six vertebral bodies underwent central stentoplasty. All fractures were of osteoporotic, traumatic or malignant aetiology. Information on vertebral body deformity, pre- and post-procedure sagittal index (SI), wedge angle (WA) and anterior vertebral height ratio was analysed. Two patients had combined ablation and stentoplasty for painful spinal metastases.
RESULTS: There were 11 male and 33 female patients with mean age of 71.5 years (51-90 years). 19 fractured vertebral bodies had more than 30% loss of height. The mean pre-procedure SI was 0.82, and the mean post-procedure SI was 0.90. The pre-procedure WA was -5.56° compared with post-procedure mean WA of -3.47°. The mean pre-procedure segmental kyphosis was -4.58°, and the mean post-procedure segmental kyphosis was -1.46°. Six cases had minimal cement leak, and two cases had a haematoma at the puncture site. None of the patients underwent revision surgery, and postoperative neurological sequelae were not observed.
CONCLUSION: 'Central stentoplasty' is a promising percutaneous vertebral fracture augmentation technique, which is shown to have low complication rates in the treatment of spinal compression fractures or metastases. However, long-term results need to be further evaluated.
