ABSTRACT
OBJECTIVES: Posterior cervical foraminotomy is a surgical procedure used to treat unilateral cervical radiculopathy. It provides direct decompression of the nerve root without the necessity of fusion while maintaining cervical mobility. With the advancement in image-guidance technology and minimal access techniques, intra-operative CT has provided a safer, more accurate instrumentation placement with less radiation exposure to operative staff and provides better anatomical visualization quality compared to traditional intra-operative imaging techniques. This case series aims to address the applications of advanced image guidance in posterior cervical foraminotomy and describe the nuances. METHOD: A technical report on a series of seven cases on intraoperative CT navigation for posterior cervical foraminotomy surgery. Posterior cervical foraminotomy was performed in all patients under CT guided navigation system without an image intensifier. In one case after the foraminotomy, the extruded disc was carefully removed by gentle retraction. RESULT: From 1 January 2020 to 31 December 2021, a total of seven patients with nine cervical foraminotomy procedures were performed using the aid of CT-guided navigation. The series comprised five women and two men whose mean age was 50.6 years. In all cases, the radiculopathy symptoms were diminished significantly. There were no cases of instability on the dynamic cervical radiograph. There were no complications during the surgical procedure. CONCLUSION: The navigation also allows the surgeon to localise the index level accurately and appraise the adequacy of the intended decompression in three planes of the CT scan image. The ability to perform accurate spine navigation would be the precursor for robotic spinal surgery.
ABSTRACT
OBJECTIVE: The coronavirus disease 2019 pandemic poses major risks to health care workers in neurocritical care. Recommendations are in place to limit medical personnel attending to the neurosurgical patient as a protective measure and to conserve personal protective equipment. However, the complexity of the neurosurgical patient proves to be a challenge and an opportunity for innovation. The goal of our study was to determine if telemedicine delivered through smart glasses was feasible and effective in an alternative method of conducting ward round on neurocritical care patients during the pandemic. METHODS: A random pair of neurosurgery resident and specialist conducted consecutive virtual and physical ward rounds on neurocritical patients. A virtual ward round was first conducted remotely by a specialist who received real-time audiovisual information from a resident wearing smart glasses integrated with telemedicine. Subsequently, a physical ward round was performed together by the resident and specialist on the same patient. The management plans of both ward rounds were compared, and the intrarater reliability was measured. On study completion a qualitative survey was performed. RESULTS: Ten paired ward rounds were performed on 103 neurocritical care patients with excellent overall intrarater reliability. Nine out of 10 showed good to excellent internal consistency, and 1 showed acceptable internal consistency. Qualitative analysis indicated wide user acceptance and high satisfaction rate with the alternative method. CONCLUSIONS: Virtual ward rounds using telemedicine via smart glasses on neurosurgical patients in critical care were feasible, effective, and widely accepted as an alternative to physical ward rounds during the coronavirus disease 2019 pandemic.
