Although the role of anterior cervical titanium plate system in stabilizing the spine sequence and promoting bone graft fusion has been widely recognized, more and more attention has been paid to the design of the plate itself and the complications caused by it. In order to solve the problems of poor stability of internal fixation, plate displacement and screw looseness, we designed the new PRUNUS spine plate system. Hence, the present study was conducted to describe observe and evaluate the clinical efficacy of a new type of three-leaf reinforced cervical anterior screw plate system (PRUNUS nailing system) developed for anterior cervical surgery.
A retrospective analysis of 56 patients from June 2018 to October 2019 was used. Twenty-seven patients with cervical spine disease treated with new PRUNUS nail plate internal fixation were selected as the observation group, and 29 patients with cervical spine disease treated with conventional cervical anterior screw fixation were selected as the control group. Postoperative follow-up was performed. Cervical stability, internal fixation position and bone graft fusion were evaluated according to imaging data. The operative time, intraoperative blood loss, cervical Cobb angle, pain visual analogue scale (VAS), and Japanese orthopaedic association (JOA) were compared between the two groups. Spinal function scores and neurological improvement rates were used to evaluate the clinical efficacy of the new PRUNUS spine plate.
The patients were followed up for 5-18 months, with an average of 7.33 months. The average operative time of the observation group was 98.4 ± 9.2 min, and the mean intraoperative blood loss was 65.3 ± 10.6 ml, which were significant different from the control group's 109.7 ± 9.4 minutes (P < 0.05), 72.9 ± 15.6 ml (P < 0.05). Comparison between the two groups in postoperative and final follow-up of cervical Cobb angle, JOA score and improvement rate, VAS score and preoperative comparison showed no significant differences (P > 0.05).
The new PRUNUS spine plate system can be applied to the anterior cervical spine surgery, and its clinical efficacy was similar to the traditional cervical anterior plate. But PRUNUS simplified the operation process, especially suitable for the surgical treatment of anterior cervical revision and osteoporosis patients.
尽管前路颈椎钛板系统在稳定脊柱序列和促进植骨融合方面的作用已得到广泛认可，但越来越多的人开始关注板本身的设计及其引起的并发症。为了解决内固定稳定性差、钢板移位和螺钉松动的问题，我们设计了新型 PRUNUS 脊柱钢板系统。因此，本研究旨在描述、观察和评估新型三叶加强型颈前路螺钉钢板系统（PRUNUS 钉系统）在颈椎前路手术中的临床疗效。
回顾性分析 2018 年 6 月至 2019 年 10 月收治的 56 例患者。选择采用新型 PRUNUS 钉板内固定治疗的 27 例颈椎疾病患者为观察组，选择采用常规颈椎前路螺钉固定治疗的 29 例颈椎疾病患者为对照组。术后随访。根据影像学资料评估颈椎稳定性、内固定位置和植骨融合情况。比较两组患者的手术时间、术中出血量、颈椎 Cobb 角、疼痛视觉模拟评分（VAS）和日本矫形协会（JOA）评分。采用脊柱功能评分和神经功能改善率评价新型 PRUNUS 脊柱钢板的临床疗效。
患者随访 5-18 个月，平均 7.33 个月。观察组患者的平均手术时间为 98.4±9.2min，术中平均出血量为 65.3±10.6ml，均明显低于对照组的 109.7±9.4min（P<0.05）、72.9±15.6ml（P<0.05）。两组患者术后及末次随访时颈椎 Cobb 角、JOA 评分及改善率、VAS 评分与术前比较，差异均无统计学意义（P>0.05）。
新型 PRUNUS 脊柱钢板系统可应用于颈椎前路手术，其临床疗效与传统颈椎前路钢板相似。但 PRUNUS 简化了手术操作过程，尤其适用于颈椎前路翻修和骨质疏松患者的手术治疗。
