Introduction: O-arm™Complete Multidimensional Neurosurgical Imaging System usefulness in traumatic spinal injuries management at a tertiary care level I apex centre is presented.
Methods: It is basically a C-arm imaging system and a CT scanner. It gives high quality multiplanar views with very high quality 3-D volume imaging during surgical procedures. O-arm imaging involves decreased imaging time in the OR. Scan time is faster and the robotic repositioning to acquire additional images is automatic. Over a period of last 12 months, 98 cases of traumatic spinal injuries have been successfully treated.
Results: The various injuries included traumatic CVJ,odontooid fractures, upper dorsal spinal fracture dislocation, dorsolumbar spinal fractures. Over 92% accurate screw placement ( class I )was noted in all cases. Recently, 12 cases have been done using percutanous instrumentations under neuronav guidance achieving satisfactory reduction and instrumentation.
Conclusions: The postoperative and intraoperative radiation to the surgeon and patient is reduced. It was found to be extremely useful in upper dorsal spine and C1-C2 transarticular screw insertion and saved from complications in 2 cases.There is a steep learning curve involved in it. This is the first of its kind imaging system acquired in asia and is being presently used in trauma centre. 8% grade II screw misplacement notd in present series rate warrants surgical knowledge of free hand technique to practicing surgeons .
Patient Care: Increase accuracy of screw placement in complex spinal trauma . Also usedful for resident training programme.
Learning Objectives: To see for accuracy for pedicle screw placement under neuronavigation guided surgery in complex spinal traumatic injuries
