Objective:To evaluate the accuracy and safety of cervical pedicle screw (CPS) placement under orthopaedic robot navigation system guidance.Methods:From March 2019 to February 2021, the data of 33 patients (19 males and 14 females, aged from 26 to 75 years, with an average age of 50.5 years) treated with pedicle screw fixation with the assistance of orthopaedic surgery robot through the posterior cervical spine were retrospectively analyzed. In clinical diagnosis, there was upper cervical fracture with instability in 14 patients (fracture nonunion in 2 patients), upper & subaxial cervical fracture in 1 patient, cervical spinal cord injury with spinal stenosis in 2 patients, cervical spinal stenosis in 9 patients, occipitocervical deformity in 2 patients, post-operative revision of cervical spondylosis in 2 patients, cervical intraspinal tumor in 3 patients. A total of 151 CPSs were inserted in C 1-C 7 using robot navigation system based on intraoperative three-dimensional C-arm fluoroscopy to assist in screw placement in posterior cervical surgery. Among them, 74 screws were implanted into upper cervical spine; 77 screws were implanted in the lower cervical spine. CT was used to obtain image data within 7 days after operation, and Neo classification was used to evaluate the accuracy of cervical pedicle screw placement. The patients were followed up for 2 weeks to observe the clinical symptoms and signs, and to determine whether there were surgical complications such as nerve and blood vessel injury and incision infection. Results:According to Neo classification, 91.4% (138/151) screws were completely contained in the pedicle without breaking through the pedicle cortex (grade 0). Among them, the accuracy of C 1 screws was 97.1% (34/35), C 2 screws was 92.3% (36/39), C 3 screws was 88.2% (15/17), C 4 screws was 71.4% (10/14), C 5 screws was 85.7% (12/14), C 6 screws was 93.3% (14/15), C 7 screws was 100.0% (17/17). The screw accuracy was highest in C 7, the lowest in C 4. The Kruskal-Wallis H test was performed on the accuracy of screw placement in different cervical level, and the results showed that there was no statistical difference (χ 2=1.31, P=0.971). However, a total of 13 screws were found to perforate the cortex of pedicle, although any neural or vascular complications associated with CPS placement were not encountered. Among them, 9 screws were found to perforate laterally, and 4 screws were found to perforate medially. No postoperative incision infection occurred in all cases. Conclusion:The safety of CPS placement can be effectively guaranteed with the assistance of the orthopaedic robot system.

Objective:To evaluate the impact of orthopedic robotic assistance and conventional freehand methods on surgical strategies, the safety of pedicle screw placement, and clinical efficacy in patients with upper cervical spine diseases.Methods:From January 2017 to March 2023, a total of 63 cases with upper cervical spine disease, were divided into two groups based on the screw placement technique: the robot-assisted pedicle screw placement (RA) group (41 cases) and the conventional freehand pedicle screw placement (CF) group (22 cases), were retrospectively included. These patients in the RA and CF groups underwent two types of posterior cervical surgery, including occipitocervical fusion (9 cases and 8 cases) and fixation and fusion of atlantoaxial and distal vertebrae (32 cases and 14 cases). The outcome parameters, including the disease course, surgical time, intraoperative blood loss, fluoroscopy frequency, radiation dose, hospital stay, treatment costs, complications, the rate of the pedicle screw placement, accuracy of upper cervical pedicle screw placement, and the risk factors that possibly affected the accuracy were recorded and analyzed. Postoperative follow-up was conducted for at least 6 months, and the efficacy of patients was assessed using imaging parameters, ASIS classification, VAS, and JOA scores.Results:Both groups had no screw-related complications and no spinal cord or vertebral artery injuries. In the RA group, the pedicle screw placement rates for the patients with occipitocervical fusion, and fixation and fusion of atlantoaxial and distal vertebrae were 100% (48/48) and 89.6% (138/154), respectively, far exceeding the placement rate in the CF group 42.9% (18/42) and 78.3% (54/69) (χ 2=37.403, P<0.001; χ 2=5.128, P=0.024). The fluoroscopic exposure dose and operation time of the two types of surgical patients in the RA group were both higher than those in the CF group ( P<0.05). Compared with the CF group, the accuracy of C 1 screws in the RA group increased from 42% (11/26) to 80% (51/64), with statistical significance (χ 2=13.342, P=0.004); while the accuracy of C 2 screws improved from 77% (33/43) to 88% (63/72) with no statistical difference (χ 2=2.863, P=0.413). Non-parametric correlation analysis found a significant correlation between the accuracy of C 1 and C 2 pedicle screw placement and the order of guide wire insertion in the RA group ( r=0.580, P<0.001; r=0.369, P=0.001). Postoperatively, both groups showed significant differences in cervicomedullary angle (CMA), Chamberlain angle (CL), McGregor angle, Boogard angle, Bull angle, clivus-canal angle (CCA), occipitocervical (C 0-C 2) angle, posterior occipitocervical angle (POCA), C 2-C 7 angle, and anterior atlantodental interval (ADI) ( P<0.05). The ASIA classification improved to varying degrees for both groups postoperatively, but there were no statistically significant differences between preoperative, postoperative, and last follow-up evaluations. VAS and JOA scores significantly improved for both groups postoperatively and at the last follow-up ( P<0.05). Conclusion:Both orthopedic robotic-assisted and conventional freehand pedicle screw placement techniques achieved satisfactory therapeutic effects in the treatment of upper cervical spine diseases. The orthopedic robot can effectively ensure the accuracy of upper cervical pedicle screw placement, the increase placement rate of pedicle screws in the upper cervical spine, and reduce fluoroscopy exposure. However, it is necessary to avoid the vertebral displacement caused by the priority insertion of the guide needle, which may affect the accuracy of subsequent planning.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.
