Correlation between intraoperative insertional torque of pedicle screws and bone mineral density in thoracic and lumbar spine injuries

Author(s): Dr. Atul Gangwar and Dr. Mozammil Pheroz
Abstract: Introduction: Pedicle screw fixation is becoming one of the standard methods of instrumentation in the thoracic and lumbar spine. The advantage of immediate rigid fixation with a minimum number of fused segments has been demonstrated in numerous studies
Methodology: Patients will be chosen as per inclusion and exclusion criteria. They will have radiological examination in the form of standard x-rays, CT scan of the spine and DEXA scan for bone mineral density
Results: Total 120 pedicle screws in 30 patients were inserted and available for the current study. The mean insertional torque of 120 screws was 2.72 ± 0.37Nm. There was no significant difference in the insertional torque of upper and lower pedicle screws at each fracture level. Quantitative evaluation of bone mineral density with DEXA scan was done of all patients. The mean BMD was found 856.7 ± 55.35 of 30 patients.
Conclusion: A high correlation was found between the mean insertional torque and Bone mineral density (r2=0.6979, p<0.0001)
