摘要

目的：负重计算机断层扫描（WBCT）创建彩色编码距离图（DM）来分析关节内接触区域，提供关节表面相互作用的详细评估。然而，糖尿病的临床应用仍未得到充分的探索。本研究引入了“战舰技术（BST）”来评估距骨弓骨关节炎（OA）患者的接触面积模式，产生一个代表距离图加权和（DMWS）的单点。DMWS可作为评估后足畸形和指导临床决策的潜在参考，包括手术计划和对齐纠正。我们假设BST对于计算DMWS是可靠的，并且DMWS与后足对齐相关，为改进复杂畸形的评估提供了一种新的工具。主要目的是评估BST的可靠性，次要目的是确定DMWS是否受到后足对准的影响。方法对40例踝关节骨性关节炎患者进行BST评分，由两名评分员独立计算DMWS。根据DMWS相对于关节中心的位置，将患者分为冠状（内翻/外翻）和矢状（前/后）组。组间后足对齐比较有统计学意义。结果观察到良好的观察者之间和观察者内部的一致性。冠状面组α角、胫距面角（TSA）、后足对线角（HFA）和距骨倾斜度（TT）差异显著（p = 0.047, p < 0.001, p = 0.003和p = 0.04），矢状面组β角和胫距比（TTR）差异显著（p < 0.001）。DMWS与TSA （r = 0.6, p < 0.001）、TT （r = - 0.6, p < 0.001）、β角（r = 0.2, p < 0.001）和TTR （r = - 0.4, p < 0.001）之间存在相关性。结论BST能可靠地计算出DMWS，并与足、踝对中有关。BST提供了一种标准化、无创的方法来评估关节内接触模式，为术前计划和术后评估提供了有价值的见解。将其整合到实践中可以提高复杂调整过程的手术精度。证据等级四级。

The Battleship technique: A reliable method to quantify intraarticular distance maps patterns and correlate hindfoot alignment

Purpose

Weight-bearing computed tomography (WBCT) creates colour-coded distance maps (DM) to analyze intraarticular contact areas, offering a detailed assessment of joint surface interactions. However, clinical applications of DM remain underexplored. This study introduces the ‘Battleship technique (BST)’ to evaluate contact area patterns in patients with osteoarthritis (OA) of the talar dome, producing a single point representing the distance map weighted sum (DMWS). The DMWS serves as a potential reference for assessing hindfoot deformities and guiding clinical decisions, including surgical planning and alignment correction. We hypothesize that the BST is reliable for calculating the DMWS and that the DMWS correlates with hindfoot alignment, providing a novel tool to improve the evaluation of complex deformities. The primary aim was to evaluate the reliability of the BST, and the secondary aim was to determine whether the DMWS is influenced by hindfoot alignment.

Methods

Two raters independently calculated DMWS using BST for forty ankle OA patients. Based on DMWS location relative to the joint centre, patients were categorized into coronal (varus/valgus) and sagittal (anterior/posterior) groups. Hindfoot alignment was statistically compared between groups.

Results

Excellent interobserver and intraobserver agreement was observed. Significant differences were found in α angle, tibiotalar surface angle (TSA), hindfoot alignment angle (HFA) and talar tilt (TT) (p = 0.047, p < 0.001, p = 0.003 and p = 0.04) between coronal groups, and in β angle and tibiotalar ratio (TTR) (p < 0.001) between sagittal groups. Correlations were identified between DMWS and TSA (r = 0.6, p < 0.001), TT (r = −0.6, p < 0.001), β angle (r = 0.2, p < 0.001) and TTR (r = −0.4, p < 0.001).

Conclusion

The BST reliably calculates the DMWS, correlating with foot and ankle alignment. BST provides a standardized, non-invasive method to evaluate intraarticular contact patterns, offering valuable insights for preoperative planning and post-operative assessment. Its integration into practice may enhance surgical precision in complex realignment procedures.
