摘要
本尸体报告旨在介绍两种不常见的腿部后室变异同时存在的情况。这些变异是在对一具 84 岁的男性遗体进行经典解剖时发现的。在左下肢,腓肠肌被发现有第三个头与外侧头相连。这种变异被称为 "腓肠肌第三头"(gastrocnemius tertius muscle),双侧均可识别。左侧的跖肌有两个不同的头,融合成一条共同的肌腱,插入小关节结节。了解这些变异非常重要,因为它们与腘窝神经血管束关系密切。临床医生应注意避免误诊,并在鉴别诊断时加以考虑。
A bilateral gastrocnemius tertius coexisting with a unilateral two-headed plantaris muscle.
The current cadaveric report aims to present a coexistence of two uncommon variants of the posterior leg compartment. The variations were detected, during classical dissection in an 84-year-old donated male cadaver. On the left lower limb, the gastrocnemius muscle was identified as having a third head that was attached to the lateral head. This variant is known as gastrocnemius tertius muscle and was bilaterally identified. The left-sided plantaris muscle had two distinct heads that fused into a common tendon that was inserted into the calcaneal tuberosity. Knowledge of these variants is important, due to their close relationship with the popliteal neurovascular bundle. Clinicians should be aware, to avoid pitfalls and take them into account in their differential diagnosis.
