PURPOSE: To evaluate and examine the efficacy of two minimally invasive strategies (percutaneous pedicle screw with intermediate screw vs. percutaneous pedicle screw with kyphoplasty) for spinal fracture fixation by evaluating the segmental kyphosis and vertebral kyphosis angles after trauma earlier than surgical procedure, after surgical procedure, and at Four-month and 12-month follow-up.
METHODS: Knowledge from 49 sufferers with out neurological deficit handled by both percutaneous pedicle screw with intermediate screw or percutaneous pedicle screw with kyphoplasty have been retrospectively analysed. The segmental kyphosis and vertebral kyphosis angles over time have been calculated and correlated with the kind of process, AO classification, lumbar or thoracic website and the age and intercourse of the sufferers.
RESULTS: After surgical procedure, each strategies have been discovered to be efficacious technique of bringing a few important correction of the segmental kyphosis angle (p = zero.002) and a simply important correction of the vertebral kyphosis angle (p = zero.06), though much less successfully in thoracic fractures (p = zero.004). At follow-up, the vertebral kyphosis angle was secure in each teams, whereas there was a major lack of segmental kyphosis angle stability within the percutaneous pedicle screw with kyphoplasty group at 1 yr (p = zero.004); fractured thoracic vertebrae maintained a better vertebral kyphosis angle (p = zero.06) and segmental kyphosis angle (p < zero.001), than the lumbar.
CONCLUSION: At 1 yr after surgical procedure, using intermediate screws in fractured vertebrae appeared to take care of a extra efficacious correction with respect to kyphoplasty, though thoracic fracture websites seem like related to better post-traumatic segmental kyphosis and lesser stability in the long run after each percutaneous surgical strategies.
