背景资料：本研究的目的是评价负重CT（WBCT）标记物明显的关节周围半脱位（PTS）和MRI结果的软组织功能不全的灵活进行性塌陷足畸形（PCFD）患者之间的相关性。我们假设，显着的相关性将found.Methods：回顾性比较研究与54灵活的PCFD患者。评估了WBCT和MRI变量畸形严重程度，包括明显的PTS标志物以及软组织变性。采用多元回归分析和分区预测模型评价骨排列与软组织损伤之间的关系。小于0.05的P值被认为是显著的。结果：胫骨后肌腱的退化与跗骨窦撞击显著相关（p = 0.04）。弹簧韧带退化与距下关节半脱位相关（p = .04）。距跟骨间韧带受累是唯一与腓骨下撞击显著相关的（p = 0.02）。结论：我们的研究结果表明，WBCT标记的明显畸形和PTS显着相关的MRI参与PTT和其他重要的限制，如弹簧和距跟骨骨间韧带。证据等级：III级，回顾性比较研究。(c)2020年欧洲足踝协会。由爱思唯尔有限公司出版。保留所有权利。
Background: The objective of this study was to evaluate the correlation between Weightbearing CT (WBCT) markers of pronounced peritalar subluxation (PTS) and MRI findings of soft tissue insufficiency in patients with flexible Progressive Collapsing Foot Deformity (PCFD). We hypothesized that significant correlation would be found. Methods: Retrospective comparative study with 54 flexible PCFD patients. WBCT and MRI variables deformity severity were evaluated, including markers of pronounced PTS, as well as soft tissue degeneration. A multiple regression analysis and partition prediction models were used to evaluate the relationship between bone alignment and soft tissue injury. P-values of less than .05 were considered significant. Results: Degeneration of the posterior tibial tendon was significantly associated with sinus tarsi impingement (p = .04). Spring ligament degeneration correlated to subtalar joint subluxation (p = .04). Talocalcaneal interosseous ligament involvement was the only one to significantly correlate to the presence of subfibular impingement (p = .02). Conclusion: Our results demonstrated that WBCT markers of pronounced deformity and PTS were significantly correlated to MRI involvement of the PTT and other important restraints such as the spring and talocalcaneal interosseus ligaments.
