To evaluate the safety and effectiveness of the lateral or posterolateral percutaneous vertebroplasty (PVP) of osteolytic C1-C2 lesions performed under computed tomography (CT) guidance and local anesthesia.Retrospective study of 16 consecutive patients (11 females and 5 males, aged from 24 to 86 years, median 65.5 years) who underwent 17 lateral or posterolateral PVP. Pain status was assessed using a visual analog scale (VAS). Patients were evaluated preoperatively as baseline and at 24 hours, 1, 6, 12 months postoperatively, or until the patient died or was lost to follow-up. The Oswestry Disability Index (ODI) was used to evaluate the patients' functional disability preoperatively. The adverse events were recorded using the SIR classification.The technical success was 100% (17/17) for a median SINS score about 13.5 (IQR [6.75, 20.25]). Mean clinical follow up was 10.1 months (range, 6-36 months; median 19.5 months, IQR [4, 35]). Mean VAS score decreased significantly from 7.5 ± 2.1 preoperatively to 1.6 ± 1.5 24 hours postoperatively, and 1.0 ± 1.1, 1.5 ± 1, and 0.5 ± 1.5 at 1, 6, 12 months respectively (all p<.001). No severe adverse events were observed but 3 cases of asymptomatic cement leakage (SIR grade 1) (17.6% (3/17)).Lateral and posterolateral PVP performed under CT guidance and local anesthesia is safe and effective to treat symptomatic osteolytic C1-C2 lesions.
