Summary
PURPOSE: This research goals to discover a protected and easy-to-perform technique for lumbar pedicle screw insertion primarily based on anatomical landmarks.
METHODS: From March 2011 to January 2012, 74 sufferers underwent posterior lumbar interbody fusion or transforaminal lumbar interbody fusion utilizing the new-designed screw insertion approach. Throughout the operation, the entry website for screw insertion was on the outer fringe of the superior side joint, four mm downward from higher border of processus transversus. A connecting line between superior and inferior side joints was used to find out the course of screw insertion. Postoperative radiograph and computed tomography (CT) had been taken routinely to indicate the place of the screws. Practical outcomes had been evaluated utilizing Oswestry Incapacity Index rating, Japanese Orthopedic Affiliation rating, and Visible Analogue Scale, respectively.
RESULTS: Sixty-two sufferers (27 males and 35 females, common age 58.95?±?eight.45) completed the follow-up go to with a mean of 46.03 months (36-60). The imply operation time and the blood loss had been 169.60?±?41.21 min and 489.52?±?189.38 ml, respectively. A complete of 274 pedicle screws had been inserted following the brand new approach. In keeping with Lothar Wiesner’s classification, 11 screws (four.01%) brought about minor violation into wall, two screws (zero.73%) brought about reasonable violation, and different screws had been in correct place.
CONCLUSION: A brand new-designed surgical technique for pedicle screw insertion of lumbar backbone was launched and carried out, which featured a collection of authentic and simply distinguished landmarks. Scientific software demonstrated the security and effectiveness of this novel approach for pedicle screw insertion.
