The purpose of this study is to evaluate the effectiveness of sonography to accurately identify interdigital neuromas. Twenty patients, all complaining of interdigital neuroma type pain, underwent sonographic evaluation of the symptomatic intermetatarsal space and adjacent interspaces. Each patient subsequently had surgical exploration of the symptomatic site. Fourteen patients had sonographic evidence of neuromas which were confirmed surgically; one patient had sonographic evidence of a neuroma that was not confirmed surgically. The remaining five patients did not have sonographic or surgical evidence of neuroma in spite of clinical signs and symptoms. No adjacent neuromas were appreciated. The correlation of sonography and clinical measurements was determined using Pearson's product moment correlation coefficient (r = 0.804, p < 0.001). Measurements performed with ultrasound were highly correlated with surgical findings. The mean size (standard deviation) of neuromas identified with ultrasound and during surgical inspection was 5.35 mm. (1.36) and 5.43 mm. (1.04). Ultrasound demonstrated a sensitivity of 100% and a specificity of 83.3%. Ultrasound was able to accurately predict the presence, size, and location of Morton's neuromas.
本研究的目的是评估超声准确识别趾间神经瘤的有效性。20例均主诉有趾间神经瘤样疼痛的患者接受了对有症状的跖间隙及相邻间隙的超声评估。随后，每位患者均对有症状的部位进行了手术探查。14例患者的神经瘤有超声证据且经手术证实；1例患者的神经瘤有超声证据但未被手术证实。其余5例患者尽管有临床体征和症状，但并无神经瘤的超声或手术证据。未发现相邻神经瘤。使用Pearson积矩相关系数确定超声与临床测量值的相关性（r = 0.804，p < 0.001）。超声测量结果与手术发现高度相关。超声检查和手术探查所发现的神经瘤的平均大小（标准差）分别为5.35 mm（1.36）和5.43 mm（1.04）。超声显示敏感性为100%，特异性为83.3%。超声能够准确预测莫顿神经瘤的存在、大小和位置。
