This study compares anatomical findings at wrist level in patients with known carpal tunnel syndrome (CTS) and controls by ultrasonography (US).
Wrist-US investigations of 28 consecutive patients with 38 diagnosed, idiopathic CTS were compared to 49 healthy volunteers without history of CTS. Internal wrists dimensions, the presence of flexor muscle bellies in the carpal tunnel, and cross-sectional area of the median nerve were analyzed. The findings were correlated to gender, age, and BMI.
US demonstrated a square internal carpal tunnel configuration in CTS patients compared to controls (P < 0.001). Patients with CTS showed a trend towards the presence of flexor muscles bellies in the carpal tunnel (odds ratio 1.77, 95% CI 0.337-8.33). CTS was present in women with higher BMI (P = 0.015).
US allowed detection of specific anatomical features at wrist level in CTS patients. This observation may enable--following confirmation in larger prospective studies--risk evaluation for CTS development.
本研究通过超声检查（US）比较已知腕管综合征（CTS）患者与对照组在腕部水平的解剖学发现。
对28例连续的、确诊为特发性CTS的38例患者进行腕部超声检查，并与49例无CTS病史的健康志愿者进行比较。分析腕部内部尺寸、腕管内屈肌肌腹的存在情况以及正中神经的横截面积。研究结果与性别、年龄和体重指数相关。
与对照组相比，超声显示CTS患者腕管内部呈方形结构（P < 0.001）。CTS患者腕管内有屈肌肌腹的趋势（优势比1.77，95%可信区间0.337 - 8.33）。体重指数较高的女性患CTS（P = 0.015）。
超声能够检测CTS患者腕部水平的特定解剖特征。这一观察结果可能在更大规模的前瞻性研究得到证实后，用于CTS发病风险评估。
