There is increased interest in ultrasound (US) for the diagnosis of cubital tunnel syndrome (CuTS). We hypothesize that ulnar nerve cross-sectional area (CSA) correlates with disease severity and electrodiagnostic studies (EDX).
ARetrospective review was performed at a tertiary medical center. One hundred seventeen patients (166 ulnar nerves) were evaluated. Maximum CSA at 3 points around the elbow (proximal, groove, and distal) and EDX results (American Board of Electrodiagnostic Medicine-certified physiatrist's interpretations) were collected.
US was positive (CSA > 0.1 cm) in 95/117 cases (81.20%) versus 84/117 (71.79%) positive for EDX. CuTS patients treated surgically had significantly greater (0.13 cm, standard deviation [SD] 0.038) preoperative CSA than non-operative patients (0.10 cm, SD 0.033) ( = .003). CSA increased as EDX increased in severity; mild (0.116 cm, SD 0.031), moderate (0.121 cm, SD 0.035), and severe (0.163 cm, SD 0.047) with a significant difference between the mild and severe groups ( = .001) and between the moderate and severe groups ( = .01). Significant differences were seen between patients with positive US and EDX studies compared to those with negative US and EDX in the average physical function scores (57.26, SD 8.57 versus 43.18, SD 7.70; < .001); average sleep scores (50.14, SD 9.53 versus 56.62, SD 7.31; = .02); average physical function scores (43.04, SD 8.68 versus 57.08, SD 6.34; < .001) and average depression scores (49.10, SD 10.88 versus 45.043, SD 7.06; = .02).
US is a reliable tool for diagnosis and surgical decision-making for CuTS.

超声（US）在诊断肘管综合征（CuTS）方面的应用越来越受到关注。我们假设尺神经横截面积（CSA）与疾病严重程度及电诊断研究（EDX）相关。
在一家三级医疗中心进行了一项回顾性研究。对117例患者（166条尺神经）进行了评估。收集了肘部周围3个点（近端、沟部和远端）的最大CSA以及EDX结果（由美国电诊断医学委员会认证的物理治疗师的解读）。
超声检查阳性（CSA>0.1 cm）的病例有95/117例（81.20%），而EDX检查阳性的有84/117例（71.79%）。接受手术治疗的CuTS患者术前CSA显著大于非手术患者（0.13 cm，标准差[SD]0.038）（0.10 cm，SD 0.033）（P = 0.003）。随着EDX严重程度增加，CSA也增加；轻度（0.116 cm，SD 0.031）、中度（0.121 cm，SD 0.035）和重度（0.163 cm，SD 0.047），轻度和重度组之间（P = 0.001）以及中度和重度组之间（P = 0.01）存在显著差异。超声和EDX检查阳性的患者与超声和EDX检查阴性的患者相比，在平均身体功能评分（57.26，SD 8.57对43.18，SD 7.70；P<0.001）、平均睡眠评分（50.14，SD 9.53对56.62，SD 7.31；P = 0.02）、平均身体功能评分（43.04，SD 8.68对57.08，SD 6.34；P<0.001）和平均抑郁评分（49.10，SD 10.88对45.043，SD 7.06；P = 0.02）方面存在显著差异。
超声是诊断CuTS及进行手术决策的可靠工具。
