“…Fu et al, 31 examined the effects of discectomy alone against discectomy and PLIF in patients with RLDH. The clinical result was evaluated as excellent or satisfactory in 78.3% of discectomy patients and 83.3% of fusion patients.…”

Objective: The study compared the efficacy of fusion with non-fusion treatment for recurrent lumbar disc herniation. Materials & Methods: 60 patients including 30 – 65 years of either gender, with recurrent disc herniation and radicular pain from at least six months after primary lumbar disc surgery. Epidural scar tissues were separated and partly resected in patients with RLDH (recurrent lumber disc herniation) undergoing standard revision discectomy (Group A). Posterolateral fusion and trans-pedicular screw fixation were used in Group B. Following the implantation of a subcutaneous suction drain, the closure was performed as usual. The effectiveness was evaluated. The Japanese Orthopedic Association's core was used to measure clinical complaints before and after surgery. Results: Most of the patients (58.33%) were 46 – 65 years old. The mean recurrent time to primary surgery was 11.87 months. 60% of patients reported ? 12 months recurrent time in group B, and 66.6% in group A. Right side was noted in 26.67% of patients of both groups. The mean pre and post-operative JOA scores were 22.34 and 8.54, respectively. The mean recovery rate was 59.32%. This study reported the efficacy of non-fusion treatment versus fusion treatment as 16.67% and 63.33%, respectively. Conclusion: We concluded that the fusion treatment is better than the non-fusion treatment for recurrent lumbar disc herniation.

“…2D Fluoroscopy-based navigation could reduce radiation exposure because of less imaging time and improve operating room environment by avoiding the need for real-time fluoroscopy [51]. In addition, 2D navigation is comparable to CT-based navigation assistance in the lumbar level [10] and realizes the reliable and accurate effect in low thoracic and lumbar spine surgery [49], [50]. Compared with 2D navigation, 3D navigation is more accurate [11], [52] and could solve all thoracic levels and lumbar levels [53].…”

In this paper, a robotic system based on intraoperative 2D fluoroscopy navigation in which fluoroscopy images are obtained by C-arm popularized in the clinic, for spine surgery is proposed. The procedure of robot-assisted spine surgery is designed and described. An improved special 6-dof hybrid robot considering both the stiffness and workspace is proposed. And the kinematic model and jacobian matrix of robot are established. To realize fluroscopy images acquisition and avoid interfering with the patient during the process of positioning, human-robot cooperation based on fuzzy variable admittance control considering arm stiffness which would influence the stability of robot, is applied in robotic system. In addition, navigation techniques containing a novel bi-planar design, a robust circular control point detector and closed-loop positioning of tool, based on fluoroscopy images are proposed. In experiments, kinematic model of hybrid robot is test based on laser tracker and the distance error is 0.17 mm which is much smaller than the motion range. The effect of tool weight compensation is measured and the max mean force and torque errors are 0.7477N and 0.0617 N.M. The experimental results could meet requirements in human-robot cooperation. Furthermore, we test the the robotic system proposed in this paper on spine model bone and cadaver with the help of surgeons. The experimental results are validated by 2D image c-arm-based and 3D image CT-based and considered clinically acceptable. INDEX TERMS Robot-assisted spine surgery system, 6-dof hybrid robot, intraoperative 2D fluoroscopy navigation, spine model bone and cadaver experiments.
