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

Unilateral TPRPA and CTPA are practical and feasible methods in PVP for the treatment of OLCF, and they have similar clinical effects. However, TPRPA has the advantages of a better distribution of bone cement and a shorter operation time and a better maintenance effect of injured vertebra height, without increasing the rate of bone cement leakage.
