The feasibility of a new self-guided pedicle tap for pedicle screw placement: an anatomical study – Published Article

Day Case Lumbar Fusion Surgery

This article discusses a study that investigates the safety and accuracy of a new self-guided pedicle tap for assisting in pedicle screw placement. The researchers developed a tap based on the anatomical and biomechanical characteristics of the pedicle. The experiment involved tapping the T1-L5 segments of eight adult spine specimens using both conventional taps (control group) and the new self-guided pedicle taps (experimental group). The placement time of the screws was recorded and compared. The safety and accuracy of screw placement were evaluated through CT scanning and graded according to the Heary grading criteria. The results showed no statistically significant difference in placement time between the two groups, but the experimental group had a higher percentage of Heary grade I and grade I+II screws, indicating greater accuracy. The authors conclude that the new self-guided pedicle tap is a safe and accurate method for placing thoracic and lumbar pedicle screws, offering a low-cost and convenient procedure with potential clinical application

ABSTRACT

PURPOSE: To investigate the safety and accuracy of applying a new self-guided pedicle tap to assist pedicle screw placement.

METHODS: A new self-guided pedicle tap was developed based on the anatomical and biomechanical characteristics of the pedicle. Eight adult spine specimens, four males and four females, were selected and tapped on the left and right sides of each pair of T1-L5 segments using conventional taps (control group) and new self-guided pedicle taps (experimental group), respectively, and pedicle screws were inserted. The screw placement time of the two groups were recorded and compared using a stopwatch. The safety and accuracy of screw placement were observed by CT scanning of the spine specimens and their imaging results were graded according to the Heary grading criteria.

RESULTS: Screw placement time of the experimental group were (5. 73 ± 1. 18) min in thoracic vertebrae and (5. 09 ± 1. 31) min in lumbar vertebrae respectively. Screw placement time of the control group were respectively (6. 02 ± 1. 54) min in thoracic vertebrae and (5.51 ± 1.42) min in lumbar vertebrae. The difference between the two groups was not statistically significant (P > 0. 05). The Heary grading of pedicle screws showed 112 (82.35%) Heary grade I screws and 126 (92.65%) Heary grade I + II screws in the experimental group, while 96 (70.59%) Heary grade I screws and 112 (82.35%) Heary grade I + II screws in the control group.The difference between the two groups was statistically significant (P < 0.05).

CONCLUSION: The new self-guided pedicle tap can safely and accurately place thoracic and lumbar pedicle screws with low-cost and convenient procedure,which indicates a good clinical application value.

The feasibility of a new self-guided pedicle tap for pedicle screw placement: an anatomical study

Sciatica My mother was in absolute agony for more than 3 months due to sciatica. It just came out of nowhere and took her out of action. From working full time she went straight to being bed bound and unable to carry out simplest of actions.The pain was 9/10 and she was bed bound for those three months. Multiple trips to A&E and GP and they wouldn't class it as an emergency therefore they wouldn't do anything about it other than upgrading the painkillers which did next to nothing for my mother. I couldn't bear to watch my mother sleeping on A&E bench in pain for 7 hours, just to be told by doctors that she wouldn't be kept in. I remember her joining her hands and begging the doctors to stop the pain which broke my heart. I then started doing research on google and London spine unit came up with Dr Mo AKMAL's profile and review. First meeting with Dr AKMAL was via ZOOM as my mother was bed bound. Dr AKMAL spoke to me and my mom and told us that this is nothing to worry about and that the pain would be 100% gone.Dr AKMAL assured us to visit the hospital so he could physically inspect my mother and give us the best solution. One trip to the london spine unit and Dr AKMAL advised us that the best solution would be to carry out Minimally invasive disectomy. Dr AKMAL advised that due to my mother being bed bound for a while, steroid injection might not give the result that my mother wishes. Dr AKMAL was very confident and showed us some videos from other patients who had gone through the same ordeal. The biggest thing i noticed between before and after was the smile on the patients face. Dr AKMAL was constantly assuring my mother throughout the meeting that he would take care of her pain and gave her 100% confidence that the result would be delivered.He promised her that she would be walking pain free the same day after the operation. Before the operation Dr GURUNG was consulted multiple times and he also was very helpful. Right after the surgery, as Dr AKMAL promised, my mother was walking and the biggest thing was that the pain was gone. My mother had forgotten to smile for three months and there i saw her smiling again. Dr AKMAL and Dr GURUNG gave us brilliant aftercare and informed us that just give them a ring if there was any issue. Its been several weeks now and my mother is heading towards complete recovery without any issues. The pain is completely gone and anyone who is reading this going through the same horrible sciatica pain you must come and see Dr AKMAL. Thank you Dr AKMAL and your whole team for helping my mom achieve this pain free life.
