Purpose: To evaluate difference in accuracy of pedicle screw insertion in thoracic and lumbosacral spine using a straight pedicle probe vis-à-vis a curved one.
Methods: Prospective, comparative, non-randomized, single-blind study. Straight and curved pedicle probes used on opposite sides of same vertebra in patients undergoing thoracolumbar pedicle screw fixation for various indications. Postoperative blinded evaluation for pedicle breaches done with a CT scan. Pedicle breaches graded as zero-no breach, one-<2mm, two-2-4mm and three->4mm breach.
Results: After appropriate statistical power analysis, 300 screws inserted in fifty-nine patients from T4-L5 levels.No significant differences noted between the two probes in terms of screw length [2-tailed-p=0.16]; grade 0 screws [2-tailed-p=0.49] or screws with grade 2/3 breaches [2-tailed-p=0.68]. With the right-hand-dominant operating-surgeon standing to left of patient during surgery, no difference noted between the two probes for either the right or left-side pedicle screw insertion [2-tailed-p=1]. Repeating these tests in the subset of thoracic pediclescrews too, revealed no significant difference.
Conclusions: No significant difference in outcome of pedicle screw insertion with either a straight or a curved pedicle probe.
