CT-navigation versus fluoroscopy-guided placement of pedicle screws at Each side was judged separately. Two-dimensional (2D) fluoroscopy-guided percutaneous pedicle screw (PPS) placement is currently the most widely applied instrumentation for minimally invasive treatment of spinal injuries requiring stabilization. Operative information including fusion level, number of levels fused, level of misplaced screw(s), single versus multiple misplaced screw(s), presence of known CSF leakage, and primary injury due to screw misplacement was also collected. 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. 3. Med Econ. Hardware problems were those related to the physical change of metal and screw position. In White AH, Rothman RH, Ray CD (eds). I won't be at the office but I will check my voice mail.

To investigate intraoperative reinsertion of percutaneous pedicle screw (PPS) with intraoperative CT-based navigation and to evaluate the rate of deviation of PPS at postoperative radiographic examination. were excluded from analysis. In unstable injuries, the segments above and below the level of injury may have a different orientation of the pedicle trajectory due to . This decision must be made on a case-by-case basis at the surgeons and patients discretion after a thorough discussion of the associated risks and benefits of revision surgery. concluded that the robot-assisted technique was significantly more accurate than the traditional freehand technique.39 Despite the learning curve and initial cost of obtaining technologies such as 3D fluoroscopic devices, intraoperative CT, or robotic navigational systems, the routine use of these technologies for intraoperative imaging confirmation and potential revision of misplaced screws may help spine surgeons avoid inadvertent iatrogenic morbidity for their patients and potential litigation. Despite these failures, solid spinal arthrodesis was obtained in all patients. 8,24,25,32. Three-dimensional printing versus freehand surgical techniques in the surgical management of adolescent idiopathic spinal deformity. Complications were classified as general, hardware-related, problems associated with the instrumented segments, junctional level problems, and problems related with balance (Table 2).

Screws penetrating the anterior cortex and abutting vascular structures, particularly aortic abutment with left-sided screws, which can lead to erosion and pseudoaneurysms. While the majority of claims are found to lack merit, resulting in a verdict in favor of the defendant or case dismissal,7,1316 at least 37% are considered valid.26 Regardless, payouts to plaintiffs are often substantial, averaging in the hundreds of thousands to millions of dollars in both the US and Europe.10,11,14,17,20 Communication of errors and expectations, thorough documentation, and selection of appropriate patients and surgical indications have been shown to reduce the likelihood of a successful malpractice claim.13,16,27,28 In addition, attempts at tort reform in some states have helped limit the financial burden of medical malpractice payouts through methods such as capitation.16,20,22,26 However, efforts to limit malpractice claims in the first place are greatly needed. The median time to case closure was 56.3 (35.267.2) months when ruled in favor of the plaintiff (i.e., patient) compared to 61.5 (51.477.2) months for defendant (surgeon) verdicts (p = 0.117). Most of these complications were minor and with the exception of two misplaced screws, did not contribute to the occurrence of neurologic impairment or severe pain.
