Cervical vertebroplasty performed via a CT-guided posterior trans-pedicular approach is technically feasible, safe, and results in effective pain relief.
Objectives Percutaneous vertebroplasty (PV) of the cervical spine has been traditionally performed with a trans-oral or antero-lateral approach. The posterior trans-pedicular approach (PTPA) has been sporadically reported. Therefore, the aim of this study is to retrospectively assess the technical feasibility, safety, and clinical outcomes of cervical PV performed with a PTPA. Methods All consecutive patients undergoing PV in cervical levels with PTPA (under general anesthesia and computed tomography [CT] guidance) from January 2008 to November 2019 were identified. The following data were collected: patients' demographics; indication for PV; vertebral level features; procedure-related variables; and clinical outcomes including complications and pain relief. Results Thirty-two patients (18 females, 14 males; mean age 61.1 +/- 13.2 years, range 36-88) were included accounting for 36 vertebrae. Three vertebrae (3/36, 8%) were referred due to an underlying traumatic fracture, the remaining (33/36, 92%) due to a painful lytic tumor. Technical success was 97% (35/36 levels). Mean time required to deploy the trocar was 23 +/- 11 min (range 7-60). Extra-vertebral asymptomatic cement leakage was observed in 3/35 (9%) vertebral levels. One patient (1/32, 3%) developed an acute cardiogenic pulmonary edema requiring admission in the intensive care unit; another patient (1/32, 3%) developed localized infection to the skin entry site, which was managed conservatively. At 1-month follow-up, the mean pain in the study population was 1.0 +/- 1.1 (range 0-4/10) vs 6.2 +/- 1.4 (range 4-9/10) at baseline (p< 0.05). Conclusions Cervical PV performed via a CT-guided PTPA is technically feasible, safe, and results in effective pain relief.
