Abstract

Background: Bicondylar tibial plateau fractures are complex injuries that commonly require surgical repair. Long-term clinical outcome has been associated with discrepancies in leg alignment, instability and condylar width abnormalities. While intuitive, the degree of articular damage at time of injury has not been linked to outcomes in patients with bicondylar tibial plateau fractures. The aim of this study was to quantify percentage of articular surface cross sectional area disruption and assess for correlation between the degree of articular injury and patient reported physical function.

Methods: Retrospective cohort study at two level 1 trauma centers. 57 consecutive patients undergoing surgical repair for bicondylar tibial plateau fractures between 2013 and 2016.

Main outcome measure: Preoperative CT scans were reviewed, and the percentage of articular surface disruption cross sectional area was calculated. PROMIS® scores were collected from patients at a minimum of 2 years.

Results: 57 patients with an average age of 58 ± 14.3 years were included. The average PROMIS® score was 45.5. There was a correlation between percentage of articular surface disruption and total PROMIS® scores (0.4, CI: 0.2-0.5, p = .007) and the physical function of the PROMIS® score (0.4, CI: 0.2-0.6, p < .001).

Conclusion: Our method for calculating articular surface disruption on CT is a simple, reproducible and accurate method for assessing the degree of articular damage in patients with bicondylar tibial plateau fractures. We found that the percentage of cross-sectional articular surface disruption correlates with patient reported outcomes and physical function.

通过 CT 横截面面积测量的关节损伤程度与治疗双髁胫骨平台骨折后的身体功能有关。
背景:胫骨平台双髁骨折是一种复杂的损伤,通常需要手术修复。长期临床结果与腿部对齐度差异、不稳定性和髁宽异常有关。尽管直观,但受伤时的关节损伤程度与双髁胫骨平台骨折患者的预后并无关联。本研究旨在量化关节面截面积破坏的百分比,并评估关节损伤程度与患者报告的身体功能之间的相关性:方法: 在两个一级创伤中心进行回顾性队列研究。2013年至2016年期间,57名连续接受双髁胫骨平台骨折手术修复的患者:回顾术前 CT 扫描,计算关节面中断截面积的百分比。收集患者至少2年的PROMIS®评分:结果:共纳入 57 名患者,平均年龄为 58 ± 14.3 岁。平均 PROMIS® 评分为 45.5 分。关节面破坏百分比与PROMIS®总分(0.4,CI:0.2-0.5,p = .007)和PROMIS®身体功能评分(0.4,CI:0.2-0.6,p < .001)之间存在相关性:我们在 CT 上计算关节面破坏的方法是一种简单、可重复且准确的方法,可用于评估双髁胫骨平台骨折患者的关节损伤程度。我们发现,横截面关节面破坏的百分比与患者报告的结果和身体功能相关。

期刊介绍: Journal of Orthopaedic Surgery is an open access peer-reviewed journal publishing original reviews and research articles on all aspects of orthopaedic surgery. It is the official journal of the Asia Pacific Orthopaedic Association. The journal welcomes and will publish materials of a diverse nature, from basic science research to clinical trials and surgical techniques. The journal encourages contributions from all parts of the world, but special emphasis is given to research of particular relevance to the Asia Pacific region.
