In this subject, we present a variation of the brachioradialis muscle with two innervations on the left side in a male cadaver. After giving its muscular branches to triceps brachii muscle, radial nerve was innervating brachioradialis muscle and after that bifurcating to superficial and deep branches as its routine course. Musculocutaneous nerve was giving two branches to brachioradialis muscle in cubital fossa before ending as lateral cutaneous nerve of forearm. It is important to know the variations of the brachial plexus in surgery of upper extremity and can be used in explaining unusual clinical symptoms.

Bu çalışmada, sol üst ekstremitesinde n. radialis ve n. musculocutaneus tarafından innerve edilen m. brachioradialis’e sahip erkek kadavra ile ilgili bir varyasyon sunulmaktadır. N. radialis m. triceps brachii’ye muskuler dallarını verdikten sonra m. brachioradialis’i besliyor ve yüzeyel ve derin dallarına ayrılarak seyrine devam ediyordu. N. musculocutaneus ise fossa cubiti’de n. cutaneus antebrachiiolarak sonlanmadan önce m. brachioradialis’e giren iki dal veriyordu. Üst ekstremiteye ait ameliyatlarda cerrahların bu ve benzeri varyasyonları göz önünde bulundurmalarının önemli olacağını düşünüyoruz.
