Abstract:
To evaluate the feasibility of magnetic navigation ultrasonography system in guiding the puncture of percutaneous posterior endoscopic cervical discectomy ( PPECD ) . Methods T he cervical CT data of 6 patients with cervical spondylosis were used to made 3D printing model ,then the localized puncture of the model was guided by the magnetic navigation ultrasonography system ,1‐mm‐slice transection CT scans were obtained to confirm the placement of the needle tips after puncture . T he total puncture time and the distance between the pinpoint in the lateral and longitudinal directions from the ＂V point＂were recorded . Results All the 36 puncture operations accurately located the target segment without penetrating the spinal canal . T he average lateral distance of the needle tip from the ＂V point＂was 2 .88 mm ( 0－7 .12 mm ) ,meanw hile the average longitudinal distance was 1 .64 mm ( 0 －4 .45 mm ) ,and the the w hole process took 3 .72 min( 2 .42－5 .20 min) . T hirty‐three of 36 points were in the circle with ＂V point＂as the center and 5mm as the radius ,puncture success rate was 91% . Conclusions T he puncture model established in this study can be used as a teaching tool ,magnetic navigation ultrasonography system has successfully guided the posterior cervical intervertebral disc puncture on the model ,and there is no radiation exposure during the operation process ,which has a promising clinical application prospect .
