We aimed to determine the factors that influence the symptoms of naviculo-cuneiform (NC) coalition using radiography and computed tomography (CT).
We retrospectively reviewed the radiographic and CT findings of 37 NC coalition cases. The existence of a large pit (depth >3 mm), irregular articular surface, joint space narrowing, dorsal bony spur, subchondral sclerosis, multiple subchondral bony cysts, and intra-articular loose body were evaluated on radiographs or CT. The size of the largest subchondral bony cyst was also measured using CT. All cases were divided into two subgroups according to the symptoms. Fisher's exact test was used to distinguish the factors influencing the symptoms.
Twenty-three and fourteen feet were enrolled into the symptomatic and asymptomatic groups, respectively. The rates of the large pit on either radiograph (47.83 vs. 21.43%) or CT (65.22 vs. 28.57%) were significantly different between both groups ( p = 0.001). The mean size of the largest subchondral bony cyst on CT was also significantly greater in the symptomatic group (4.25 vs. 1.53 mm, p = 0.005).
A large deep pit and huge subchondral bony cyst on the radiograph or CT can be related to symptoms for the patient with NC coalition. A CT is highly recommended for a more accurate evaluation in patients with NC coalition.
我们旨在利用X线摄影和计算机断层扫描（CT）确定影响舟楔关节（NC）联合症状的因素。
我们回顾性分析了37例NC联合病例的X线摄影和CT表现。在X线片或CT上评估是否存在大坑（深度>3 mm）、关节面不规则、关节间隙变窄、背侧骨赘、软骨下硬化、多个软骨下骨囊肿和关节内游离体。还使用CT测量最大软骨下骨囊肿的大小。所有病例根据症状分为两个亚组。采用Fisher精确检验来区分影响症状的因素。
分别有23只足和14只足纳入有症状组和无症状组。两组之间X线片（47.83%对21.43%）或CT（65.22%对28.57%）上大坑的发生率有显著差异（p = 0.001）。有症状组CT上最大软骨下骨囊肿的平均大小也显著更大（4.25对1.53 mm，p = 0.005）。
X线片或CT上的大坑和巨大软骨下骨囊肿可能与NC联合患者的症状有关。对于NC联合患者，强烈建议进行CT检查以进行更准确的评估。
