Adjusting Lumbar Pedicle Screw After t-EMG Testing
By Admin | July 03, 2024
Detecting and correcting malpositioned screws during lumbar spine surgery is crucial to avoid nerve damage and postoperative complications. One method to identify such issues is triggered electromyography (t-EMG), which uses electric stimulation to assess proximity of nerves in relation to screws. This case study demonstrates the importance of t-EMG in ensuring patient safety and surgical success.
A 70-year-old woman with lumbar radiculopathy, stenosis, and spondylolisthesis underwent a L3-L5 Posterior Lumbar Interbody Fusion (PLIF) and Decompression. She presented with low back pain, leg pain, weakness, and numbness, indicating a need for surgical intervention to alleviate her symptoms and improve her quality of life.
During the surgery, the surgical team encountered a potential issue with the left L3 screw. Initial t-EMG testing revealed a concerning reading of 5.5 mA, suggesting that the screw might be too close to the nerve, which could lead to complications such as nerve root injury. Recognizing the importance of precise screw placement, the surgeon opted to replace the screw with a new trajectory to ensure optimal positioning and minimize the risk of postoperative complications.
Subsequent testing of the replacement screw yielded a reading of 9.5 mA and the surgeon was satisfied with the new screw placement. This proactive approach to addressing the issue with the left L3 screw demonstrates the value of intraoperative neuromonitoring techniques like t-EMG in ensuring surgical precision and patient safety. By promptly identifying and correcting potential issues during surgery, the surgical team was able to mitigate the risk of nerve damage and postoperative complications, ultimately improving the patient's overall outcome.
The integration of neuromonitoring techniques like t-EMG into spinal surgery procedures enhances surgical precision and patient outcomes. By providing real-time feedback on nerve function and screw positioning, t-EMG enables surgeons to make informed decisions and adjust their approach as needed to optimize patient care.
This case underscores the significance of intraoperative monitoring techniques like t-EMG in optimizing surgical precision and ensuring patient safety. By leveraging advanced technologies and techniques, surgeons can minimize the risk of complications and improve outcomes for patients undergoing lumbar spine surgery.
In conclusion, the successful outcome of this case highlights the transformative impact of neuromonitoring in spinal surgery. For more information on the benefits of neuromonitoring and its role in enhancing patient care, please contact us at 888-344-2947.
