The extensor hallucis longus (EHL) muscle is important for diagnosis of neurologic lesions. It is also a target muscle for treatment. We investigated EHL with ultrasonography to determine optimal needle placement for safety and accuracy.
A total of 96 legs of 48 healthy volunteers were examined through ultrasonography. Four published electromyographic methods for finding the EHL were assessed. We identified the midpoint of EHL (MD) using landmarks to determine optimal needle placement.
Mean values of bimalleolar line-MD on skin (MD-S) and tibial crest-MD-S were 10.5 ± 1.2 cm and 3.6 ± 0.4 cm, respectively. The depth of MD was 1.6 ± 0.2 cm. According to 4 EMG methods, the probability of needle penetrating EHL was 13% to 79% and that of needle penetrating the neurovascular bundle was 50% to 89%.
Using ultrasonography, we could determine optimal needle placement in the EHL. Muscle Nerve 59:331-336, 2019.
伸肌足母长肌（EHL）对于诊断神经病变很重要。它也是治疗的靶肌肉。我们通过超声检查 EHL，以确定安全准确的最佳针位。
对 48 名健康志愿者的 96 条腿进行了超声检查。评估了四种已发表的肌电图方法来寻找 EHL。我们使用标志确定 EHL 的中点（MD），以确定最佳的针位。
双踝线-MD 皮（MD-S）和胫骨嵴-MD-S 的平均数值分别为 10.5 ± 1.2 cm 和 3.6 ± 0.4 cm。MD 的深度为 1.6 ± 0.2 cm。根据 4 种肌电图方法，针穿透 EHL 的概率为 13%至 79%，针穿透神经血管束的概率为 50%至 89%。
使用超声，我们可以确定 EHL 中的最佳针位。肌肉神经 59：331-336，2019 年。
