Pull-out strength of cervical pedicle short screws and pedicle long screws and lateral mass screws,a biomechanical comparison
Objective:To determine whether the poll-out strength of cervical short pedicle(20mm) screw is comparable with that of long pedicle(28mm) screw and whether it is significantly stranger than that of lateral mass screw.Method:15 fresh cervical specimens of 5
