Unilateral percutaneous vertebroplasty for osteoporotic lumbar compression fractures: a comparative study between transverse process root-pedicle approach and conventional transpedicular approach

Abstract Purpose Percutaneous vertebroplasty (PVP) is a routine operation for the treatment of osteoporotic lumbar compression fractures (OLCFs). As well known, unilateral puncture common method. However, with conventional transpedicular approach (CTPA), cement may be asymmetrically dispersed, so some surgeons use transverse process root-pedicle (TPRPA). The objective this study was to compare clinical results and bone distribution PVP OLCF TPRPA CTPA identify advantages disadvantages two surgical options. Patients methods From January 2016 June 2019, seventy-two elderly patients who underwent single-level were retrospectively reviewed. Operation time, injection amount type distribution, leakage complications recorded. visual analog scale (VAS) scores Oswestry disability index (ODI) used evaluate results. All followed up more than 12 months, assessment based primarily on radiological outcomes. Results There significant differences in time volume lost operative vertebra height between groups. there no difference leakage. Moreover, VAS ODI groups at 2 days months after operation. Conclusions Unilateral are practical feasible OLCF, they have similar effects. has better shorter maintenance effect injured height, without increasing rate
