研究目的:

本研究旨在整合高分辨率CT基于生物力学分析与系统的临床及功能随访,明确OVCF患者椎体内空隙的形态学特征与愈合模式;评估椎体内空隙愈合状态与临床稳定性的关联;分析椎体内空隙愈合状态对患者疼痛缓解及功能恢复的影响.  

Objectives of Study:

This study aims to integrate high-resolution CT-based biomechanical analysis with systematic clinical and functional follow-up, to clarify the morphological characteristics and healing patterns of intravertebral cavities in patients with osteoporotic vertebral compression fractures (OVCF); to evaluate the correlation between the healing status of intravertebral cavities and clinical stability; to analyze the impact of the healing status of intravertebral cavities on pain relief and functional recovery in patients.

药物成份或治疗方案详述:

本研究为回顾性非干预性研究,核心特点是不实施任何主动干预措施,仅通过回顾性收集和分析临床既有数据开展研究,具体 “干预相关信息” 为患者既往接受的临床常规治疗(非研究设计的干预方案),包括: 保守治疗:镇痛药物使用、卧床休息、支具外固定、抗骨质疏松药物治疗等; 外科干预:经皮椎体成形术(PVP)、经皮球囊后凸成形术(PKP)等脊柱外科常规手术治疗。 研究仅对上述既往治疗后的患者进行随访观察,分析其临床结局与椎体内空隙(IVVs)特征的关联,不额外施加新的治疗或干预手段。 

Description for medicine or protocol of treatment in detail:

This study is a retrospective non-interventional study. Its core feature is that no active intervention measures are implemented; instead, the research is conducted solely through retrospective collection and analysis of existing clinical data. The specific "intervention-related information" refers to the routine clinical treatments previously received by patients (not intervention plans designed for this study), including: Conservative treatment: Administration of analgesic drugs, bed rest, external brace fixation, anti-osteoporotic drug therapy, etc.; Surgical intervention: Routine spinal surgical treatments such as Percutaneous Vertebroplasty (PVP) and Percutaneous Kyphoplasty (PKP). This study only conducts follow-up observations on patients who have undergone the aforementioned prior treatments, analyzing the correlation between their clinical outcomes and the characteristics of intravertebral vacuities (IVVs), without imposing any additional new treatments or intervention measures.

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:

(1)回顾性筛选符合标准的病例→收集患者基线资料(人口学特征、合并症、基线功能评分、影像学资料)→基于薄层CT分析椎体内空隙特征(数量、总体积、最大直径、空间分布、骨密度等)并判定愈合状态(愈合/未愈合)→采用改良KD-IS评分评估临床稳定性→对患者进行1、3、6、12个月随访,收集随访期内的疼痛评分(VAS)、功能评分(ODI、EQ-5D)及影像学资料→整理数据并进行统计分析→明确椎体内空隙特征与临床结局的关联,提出分层管理框架 (2)各环节生物样本/数据使用说明: •病例筛选环节:使用患者的电子病历及影像学检查报告,确认是否符合纳入排除标准; •基线资料收集环节:使用患者的人口学资料(年龄、性别)、合并症记录、基线VAS、ODI、EQ-5D评分数据,以及X线、薄层CT、MRI等影像学资料; •椎体内空隙分析环节:使用薄层CT影像数据,通过半自动化分割软件进行分析,获取空隙数量、总体积等参数,结合MRI资料判定愈合状态;同时使用CT数据计算骨折椎体及周围骨组织的骨密度; •临床稳定性评估环节:使用影像学资料(X线、CT)及临床疼痛记录,采用改良KD-IS评分进行评估; •随访环节:使用随访期内的VAS、ODI、EQ-5D评分数据,以及各时间点的X线、CT/MRI影像学资料(怀疑病情进展时); •统计分析环节:整合上述所有收集的数据,进行统计学处理。

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

Retrospectively screen eligible cases → Collect patients’ baseline data (demographic characteristics, comorbidities, baseline functional scores, and imaging data) → Analyze the characteristics of intravertebral vacuoles (quantity, total volume, maximum diameter, spatial distribution, bone mineral density, etc.) based on thin-slice computed tomography (CT), and determine the healing status (healed/unhealed) → Evaluate clinical stability using the modified KD-IS score → Conduct follow-up visits for patients at 1, 3, 6, and 12 months, and collect pain scores (VAS), functional scores (ODI, EQ-5D) and imaging data during the follow-up period → Collate data and perform statistical analysis → Clarify the correlation between intravertebral vacuole characteristics and clinical outcomes, and propose a hierarchical management framework (2) Instructions for the use of biological samples/data in each link Case screening stage: Use patients’ electronic medical records and imaging examination reports to confirm whether they meet the inclusion and exclusion criteria. Baseline data collection stage: Use patients’ demographic data (age, gender), comorbidity records, baseline VAS, ODI and EQ-5D scores, as well as imaging data including X-ray, thin-slice CT and magnetic resonance imaging (MRI). Intravertebral vacuole analysis stage: Use thin-slice CT imaging data and analyze it with semi-automated segmentation software to obtain parameters such as vacuole quantity and total volume; determine the healing status combined with MRI data; meanwhile, calculate the bone mineral density of fractured vertebrae and surrounding bone tissue using CT data. Clinical stability evaluation stage: Use imaging data (X-ray, CT) and clinical pain records to conduct evaluation with the modified KD-IS score. Follow-up stage: Use VAS, ODI and EQ-5D scores during the follow-up period, as well as X-ray, CT/MRI imaging data at each time point (when disease progression is suspected). Statistical analysis stage: Integrate all the above-collected data and perform statistical processing.
