Clinical Experience With a High-Definition Three-Dimensional Exoscope for Spinal Surgery: A Review of 30 Consecutive Initial Cases

Background: The use of exoscopes with high-definition three-dimensional displays has become increasingly common; however, their use in spinal surgery remains limited.We retrospectively evaluated initial cases of spinal surgery performed using an exoscope.Materials and methods: Between May 2019 and May 2023, we performed 30 consecutive spinal surgeries using the exoscope, including 22 lumbar decompression surgeries and eight cervical laminoplasties.We evaluated clinical outcomes using the Japanese Orthopedic Association (JOA) score, the recovery rate calculated from the JOA score, and patient self-evaluation.Results: All procedures were completed using the exoscope without switching to other visualization devices.The outcomes were satisfactory, and no patients showed postoperative worsening of the JOA score.No exoscope-related surgical complications were observed.Conclusion: This novel exoscope system demonstrated feasibility and acceptable safety in the initial cases.
