Percutaneous vertebroplasty with granulated allogeneic bone grafting using screw-view model of navigation for thoracolumbar compressive fracture: A case report.

RATIONALE: The aim of this study was to assess the accuracy of percutaneous puncture needle with screw view model of navigation (SVMN) and the effect of periacetabular vertebroplasty (PVP) with granulated allogeneic bone grafting in thoracolumbar compressive fracture (TCF).

PATIENT CONCERNS: A 46-year-old female patient associated with high fall injury showed symptoms characterized by back pain and restricted movement of the right lower extremity.

DIAGNOSES: The patient was diagnosed with a TCF, right femoral neck fracture, and lumbar vertebrae hyperosteogeny.

INTERVENTIONS: A SVMN was used to guide our puncture needle insertion; and PVP was performed with granulated allogeneic bone grafting in this patient.

OUTCOMES: The follow-up lasted for 29 months. It took 2.4 minutes to design the trajectory of puncture needle, 2.1 minutes to implant the puncture needle, and 6.3 minutes to undergone fluoroscopy. Postoperative visual analog scale and Oswestry disability index scores were improved obviously compared with those before the operation. The Cobb angle of fractured vertebrae improved from 9.3° to 7.3° after treatment. The height ratio of fractured vertebrae increased from 79.5% to 90.6% postoperatively. Intraoperative blood loss amounted to 11 ml. No clinical complications were observed, including neurovascular injury and new fracture of adjacent vertebra.

LESSONS: Puncture needle placement under the guidance of SVMN is verified as a convenient, safe and reliable method, and PVP with granulated allogeneic bone grafting can effectively restore the height of anterior fractured vertebra, filling the gaps in the fractured vertebrae, and reconstructing the completeness of the fractured vertebrae.
