研究目的:

本研究将纳入评估后确定需接受单节段ACDF的颈椎病患者,接受聚醚醚酮(polyether-ether-ketone, PEEK)椎间融合器、β-TCP骨移植替代物填充植骨窗的ACDF手术。通过含β-TCP椎间融合器对颈椎退行性疾病的治疗,对该新技术的安全性和有效性进行初步临床评价;揭示含β-TCP椎间融合器在人体中的骨修复过程。  

Objectives of Study:

This study will enroll patients with cervical spondylosis who, upon assessment, are determined to require single-level anterior cervical discectomy and fusion (ACDF). These patients will undergo ACDF surgery utilizing polyether-ether-ketone (PEEK) interbody cages filled with β-tricalcium phosphate (β-TCP) bone graft substitutes in the bone grafting window. By treating cervical degenerative diseases with β-TCP-containing fusion cages, this study aims to conduct a preliminary clinical evaluation of the safety and effectiveness of this novel technology. Furthermore, it seeks to elucidate the bone repair process of β-TCP-containing fusion cages in humans.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本研究采用病例记录表进行数据采集和管理 1. 数据录入 根据受试者的原始观察记录,研究者会将数据及时、完整、正确、清晰地载入病例报告表。经过研究者再次审核并签字后及时送交临床研究数据管理员。 采用相应的数据库系统双人双机录入,之后对数据库进行两遍比对,期间若发现问题及时通知课题负责人,并要求研究者做出回答。他们之间的各种疑问及解答的交换均采用疑问表形式,疑问表保存备查。 2. 数据核查和管理的内容和方式 当所有病例报告表经双份输入并核对无误后,数据管理员将写出数据库检查报告,内容包括研究完成情况(含脱落受试者清单)、入选/排除标准检查、完整性检查、逻辑一致性检查、离群数据检查、时间窗检查、合并用药检查、不良事件检查等。 在审核会议上,主要研究者、数据管理员和统计人员将对受试者签署知情同意书、数据库检查报告中提出的问题做出决议,写出审核报告,数据库同时将被锁定。 3. 数据存档 病例报告表在按要求完成数据录入和核查后,按编号的顺序归档保存,并填有检索目录等,以备查考。电子数据文件包括数据库、检查程序、分析程序、分析结果、编码本和说明文件等,予以分类保存,并准备多个备份保存于不同磁盘上,妥善保存,防止损坏。所有原始档案均按相应规定内的期限保存。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This study employs case record form for data collection and management. 1.Data Entry Based on the original observation records of the subjects, the researchers will promptly, completely, accurately, and clearly enter the data into the Case Report Forms (CRFs). After a second review and signature by the researchers, the CRFs will be promptly submitted to the clinical study data administrator. Data entry will be conducted by two individuals on two separate computers using the corresponding database system. Following this, the database will undergo two rounds of comparison. If any issues are identified during this process, the project leader will be promptly notified, and the researchers will be required to provide responses. All exchanges of questions and answers between them will be conducted using a question form, which will be kept for future reference. 2.Contents and Methods of Data Verification and Management After all CRFs have been double-entered and verified for accuracy, the data administrator will prepare a database inspection report. This report will include the status of the study completion (including a list of dropout subjects), checks on inclusion/exclusion criteria, completeness checks, logical consistency checks, outlier data checks, time window checks, concomitant medication checks, adverse event checks, and more. During the review meeting, the principal investigator, data administrator, and statistician will resolve issues related to subject consent forms and those raised in the database inspection report. They will then prepare an audit report, and the database will be locked simultaneously. 3.Data Archiving After the CRFs have been completed with data entry and verification as required, they will be archived in numerical order and filled with retrieval directories for future reference. Electronic data files, including databases, inspection programs, analysis programs, analysis results, codebooks, and explanatory documents, will be classified and stored with multiple backups on different disks to ensure their safety and prevent damage. All original records will be kept for the duration specified in the corresponding regulations.
