Moreover, in our study published in this journal in 2015 [1], not only were there up to five branches for the biceps brachii, but the most proximal arose as high as 17.9% of the arm length. A short incision would miss such branches. From one article to another, many different bony landmarks were used to assess the arm length. This makes comparison between studies difficult and should be standardized. The authors of the above-mentioned study dissected the two arms of eight of their ten cadavers. The branching pattern of the MCN was shown to be similar in the two limbs of the same subject in 71% of cases [5]. The small amount of arms makes it difficult to draw recommendations from anatomical observations, considering the frequent variations of MCN anatomy. The most noticeable ones are the number of motor trunks for each elbow flexor [1] and relationships with the median nerve. Anatomic knowledge of nerves branching pattern rather than length of skin incisions is crucial to perform a successful selective neurectomy in selected spastic muscles.
