The advent and widespread adoption of pedicle screw instrumentation prompted the need for image guidance in spine surgery to improve accuracy and safety. Although the conventional method, fluoroscopy, is readily available and inexpensive, concerns regarding radiation exposure and the drive to provide better visual guidance spurred the development of computer-assisted navigation.Contemporaneously, a non-navigated robotic guidance platform was also introduced as a competing modality for pedicle screw placement. Although the robot could provide high precision trajectory guidance by restricting four of the six degrees of freedom (DOF), the lack of real-time depth control and high capital acquisition cost diminished its popularity, while computer-assisted navigation platforms became increasingly sophisticated and accepted. The recent integration of real-time 3D navigation with robotic platforms has resulted in a resurgence of interest in robotics in spine surgery with the recent introduction of numerous navigated robotic platforms. The currently available navigated robotic spine surgery platforms include the
Pediatric patients with neuromuscular conditions often have nonorthopaedic implants that can pose a challenge for MRI acquisition and surgical planning. Treating physicians often find themselves in the position of navigating between seemingly overly risk-averse manufacturer's guidelines and an individual patient's benefits of an MRI or surgery. Most nonorthopaedic implants are compatible with MRI under specific conditions, though often require reprogramming or interrogation before and/or after the scan. For surgical procedures, the use of electrosurgical instrumentation poses a risk of electromagnetic interference and implants are thus often programmed or turned off for the procedures. Special considerations are needed for these patients to prevent device damage or malfunction, which can pose additional risk to the patient. Additional planning before surgery is necessary to ensure appropriate equipment, and staff are available to ensure patient safety. Patients with neuromuscular disorders often require surgical treatment to improve function, manage contractures, and correct deformity. Owing to underlying diagnoses or associated medical conditions, these patients may have medical implants to help manage muscle tone, control seizures, treat cardiac conditions, improve hearing, etc. Managing nonorthopaedic implants can cause delays and confusion when planning for advanced imaging studies and/or surgical intervention. Identifying these devices before MRI acquisition or surgical procedures is important to ensure the appropriate equipment, or support staff are available to maintain patient safety and device integrity.There is little guidance regarding the management of these implants, and manufacturer's recommendations may differ from practical application. Manufacturers' guidelines often make conservative recommendations accounting for rare worst case scenarios, but strict compliance to these guidelines may be impractical and could prevent medically necessary imaging or surgery for a patient. Treating physicians must navigate the conflict of risk-averse guidelines and patient's medical needs. Often, we rely on expert
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
