PurposeTo evaluate the effects of percutaneous vertebroplasty (PVP) with conventional transpedicle approach (CTA) or basal transverse process-pedicle approach (BTPA) on the treatment of thoracolumbar osteoporotic vertebral compression fractures (TL-OVCFs) with narrow pedicles.MethodsA retrospective study of TL-OVCFs with narrow pedicles was performed, including 78 cases of CTA and 84 cases of BTPA. The surgical outcomes, radiographic parameters [the width and height of the pedicle (PW, PH), the inclination angle of puncture (PIA)] and clinical indicators [visual analog scale (VAS) score, Oswestry Disability Index (ODI)] of two groups were compared.ResultsIn terms of surgical outcomes of them, there was no difference in operation time (P > 0.05), while the volume of bone cement, the incidence of bone cement leakage and rate of good bone cement distribution were significantly worse in the CTA group (4.4 ± 0.6 ml vs. 5.5 ± 0.5 ml, 37.2% vs. 20.2%, 52.6% vs. 79.8%, P < 0.05). As for radiographic parameters and clinical indicators of them, the differences were not observed in the PH, PW, preoperative VAS score and ODI (P > 0.05), whereas the PIA, VAS score and ODI at 1 day postoperatively were significantly better in the BTPA group (17.3 ± 2.1° vs. 29.6 ± 2.8°, 2.7 ± 0.7 vs. 2.1 ± 0.8, 32.8 ± 4.6 vs. 26.7 ± 4.0, P < 0.05).ConclusionThe study provided solid evidence that PVP with BTPA had more advantages in the treatment of TL-OVCFs with narrow pedicles, which can better relieve postoperative pain.© 2023.
