Twenty-one patients (18.8%) had thoracolumbar injuries, and loss of immediate postoperative deformity correction ranged from 1.4 to 4.5. Mayo Clinic uses the latest robot-assisted technology when indicated to enhance surgical precision in these procedures. In our opinion, these problems may be prevented by applying the following principles: limitation of spine arthrodesis to the pathologic levels, inclusion of already extensive changes at the level above or below the planned arthrodesis into the arthrodesis, restoration of postoperative sagittal and coronal alignment, and avoidance of impingement syndrome from the adjacent nonfused facets.

Alan Loren, M.D. L3S1 spine arthrodesis was done in the first patient but the correction of scoliosis was not sufficient and coronal imbalance persisted after surgery, which accelerated the degeneration of the level just above the arthrodesis. Although the rate of the reported medical complications was high (36.5%), these did not significantly affect the final clinical outcome of the current patients. In addition, the median time to judgment is substantial, particularly for defendant verdicts, spanning over 4.5 years from the time of surgery. The highly litigious environment within healthcare has resulted in a majority of physicians practicing defensive medicine,15 often leading to burnout6,7 and an exorbitant ethical and financial burden on medical and surgical care.7,8 In 2008, medical liability accounted for $55.6 billion, representing 2.4% of the United States (US) healthcare expenditures that year,5,7,9,10 and the pervasive practice of defensive medicine may cost up to $210 billion annually in the US.5 A similar trend has been observed in Europe.11, Neurosurgery is the specialty most frequently affected by lawsuits and the fear of litigation, both in the US and abroad,12 with spine surgery at the forefront.11,1317 As a result, spine surgeons are nearly three times more likely than nonspine surgeons to practice defensive medicine, defined as the avoidance of high-risk procedures and the provision of unnecessary services and assessments beyond what is clinically necessary in an effort to avoid litagation.5 The average time to judgment in a case is approximately 5.1, 5.0, and 3.4 years for defendant verdicts, plaintiff rulings, and settlements, respectively.7,15 As a result, physicians spend an average of 11% of their careers dealing with one or more open malpractice claims.18 Neurosurgeons are especially impacted, spending an average of 27.2% of their careers in an open lawsuit.10. We attribute the 24.1% disc space narrowing in the instrumented segments mainly to the severe injury of the disc and communication of the end plate in burst fractures, which could accelerate the disc degeneration and narrowing.

Conclusion: Results: A total of 2724 screws were placed in 127 patients. The rate of reoperation for screw misplacement per screw was 0.17%. Problems of balance were coronal (scoliosis greater than 5 or trunk shift greater than 5 mm) as seen on the AP radiograph taken with the patient standing or sagittal (failure to obtain or maintain lumbar lordosis). 16,24,28 Simultaneously, the evolution of the surgical techniques has led to increased procedural safety. Despite commonly used, questions remain about their safety especially for the thoracic spine and in deformity where difficulty in positioning can lead to pedicle breach and adjacent structures injury.

This study quantifies the rate of screw misplacement on a per-patient basis to highlight its effect on potential morbidity. Finally, considering the problems of balance, it seems that failure to properly evaluate any preexisting scoliosis was a main cause of this important complication. Pedicle screw placement is a common procedure. However, 5-10% of those misplaced screws are cause for concern." "To rectify this, we must have access to imaging devices during the procedure. leg pain. Stauffer RN, Coventry MB: Posterolateral lumbar-spine fusion: Analysis of the Mayo clinic series. 3. In four of these patients, bent screws occurred at 8 to 10 months after surgery; in three patients, broken screw necks were seen 1 year after surgery and in two patients, tulip screw plug dislodgments were observed at 4 and 6 months postoperatively, respectively. Ahmadi SA, Sadat H, Scheufler KM, et al. Katonis, Pavlos MD*; Christoforakis, Joseph MD*; Aligizakis, Agisilaos C.
