Abstract

Purpose In patients requiring percutaneous kyphoplasty (PKP) for painful cervical spine metastases (PCSMs), the surgical approach is of utmost importance. Anterolateral and transoral routes are generally used at present, whereas PKP as well as percutaneous pediculoplasty (PPP) via posterolateral transpedicular approach (PTPA) has yet to be pursued in the treatment of PCSMs. The study was designed to evaluate safety and efficacy of PKP procedures combined with PPP via PTPA as treatment of PCSMs. Patients and Methods The patients with PCSMs were enrolled and housed in a database. The pain intensity of enrolled patients was gauged by Visual Analog Scale (VAS), ranging from 0 (none) to 10 (extreme). After preprocedural imaging assessment, combined PKP/PPP via PTPA was performed under the guidance of CT and fluoroscopic monitoring. Postprocedural VAS scores, complications, cement dosage, and hospitalization were recorded in the database for analysis. All cases were followed up for 6 months. Results Adult enrollees (7 women, 4 men) with PCSMs successfully underwent PKP/PPP via PTPA between February 2019 and January 2020, injected with 3.7±0.7 mL (range, 2.5–4.8 mL) of cement on average. Other than a single instance of asymptomatic cement leakage into paravertebral soft tissues, no complications ensued. Significant analgesic effects observed 24 hours after procedures were sustained for up to 6 months in follow-up surveys. Postprocedural hospitalizations were as brief as 2.2±0.8 days. Conclusion Combined PKP/PPP via PTPA is safe and effective as treatment of PCSMs, enabling quick pain relief and patient recovery.
