Objective:To evaluate the clinical efficacy of pushing reduction with our self-designed spinal fracture reduction device in the treatment of A3N0/1 thoracolumbar fractures.Methods:A retrospective study was conducted to analyze the medical records of 53 patients who had undergone surgery for thoracolumbar vertebrae fracture at Department of Minimally Invasive Spine Surgery, Zhengzhou Orthopedic Hospital from January 2019 to January 2022. All patients were treated by internal fixation via the Wiltse approach and bone grafting through the pedicle of the injured vertebrae. Clinical data: 35 males and 18 females; age: (37.8±10.2) years; injured segments: 23 cases at the thoracic spine and 30 cases at the lumbar spine; time from injury to surgery: (3.3±1.5) days. According to whether our self-designed spinal fracture reduction device was used or not, the patients were assigned into group A (23 cases) in which the injured vertebrae were pushed and reduced using our novel spinal fracture reduction device after vertebral distraction reduction by the pedicle screw and group B (30 cases) in which the injured vertebrae were distracted and reduced using the pedicle screw alone. The operation time, intraoperative blood loss and complications were compared between the 2 groups. The anterior vertebral body height ratio (AVBHr), middle vertebral body height ratio (MVBHr), posterior vertebral body height ratio (PVBHr), Cobb angle of the injured vertebra, visual analogue scale (VAS) and Oswestry disability index (ODI) at preoperation, postoperative 3 and 6 months, and the last follow-up were compared between the 2 groups.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (16.3±5.9) months. All incisions healed at one stage postoperatively without any related complications. The operation time in group A was significantly longer than that in group B [(115.1±16.6) min. versus (101.0±11.5) min.], the intraoperative blood loss in group A was significantly greater than that in group B [(136.5±17.0) mL versus (121.6±19.8) mL], the MVBHr at postoperative 3 months in group A (93.9%±4.0%) was significantly better than that in group B (83.3%±7.6%), and the MVBHr, AVBHr, Cobb angle, VAS, and ODI at the last follow-up in group A [86.6%±5.5%, 89.8%±4.1%, 4°(4°, 6°), 1 (0, 1) point, and 4.7%±2.0%] were significantly better than those in group B [78.0% (74.0%, 79.0%), 84.5%±4.9%, 12.2°±3.3°, 2 (1, 3) points, and 7.3%±2.7%] (all P<0.05). However, there was no statistically significant difference in PVBHr between the 2 groups at postoperative 3 months or at the last follow-up ( P>0.05). Conclusion:In the treatment of A3N0/1 thoracolumbar fractures, pushing reduction with our self-designed spinal fracture reduction device can directly and effectively reduce the fracture zone of the injured vertebra, which is conducive to maintaining postoperative vertebral reduction, reducing vertebral height loss and kyphotic deformity at a later stage, relieving lumbar pain and improving lumbar spine function.

The construction of regional medical centers is an important carrier for the country to further promote the reform of the new medical service system during the"14th Five-Year Plan"period.In view of the problems existing in the current construction of national regional medical centers,such as imperfect coordination mechanism,insufficient coordination power and lack of assessment and evaluation system,drawing on collaboration theory and case study method,the construction path of national regional medical centers was analyzed from three dimensions:management system collaboration,operation mechanism collaboration and evaluation mechanism collaboration;It explore and constructs the new management model of"13331"high quality development in National Regional Medical Centers;The results provide experience and case reference for promoting the high-quality development of national regional medical centers under the new situation in terms of party building leadership,medical technology,scientific and technological innovation,medical-education collaboration and brand influence.
