Variations in the arteries, nerves and muscles of the upper limb have both academic and clinical relevance. These variations could be of importance for the clinical practice and there are many clinical case reports presenting their significance for orthopedics, plastic surgeons and neurologists. [8][9][10][11][12][13][14] Therefore, knowledge of these anomalous structures and especially cases with multiple coexisting variations, although rare, is important not only to anatomists but also to clinicians in their routine practice.In this report, we describe the co-existence of the aforementioned variations and emphasize on their clinical implications.
Case ReportMultiple anatomical variations in the forearm were discovered on the left side of a 70-year-old male cadaver during routine dissection. No variations in the contralateral right upper extremity were discovered. The left-side variations were as follows.
Variation of the palmaris longusThe variant palmaris longus arose as usual from the medial epicondyle of the humerus, with the other flexor muscles of the forearm and from the antebrachial fascia.
AbstractIn this report we describe an unusual combination of anatomical variations in the left upper extremity. A rare case of a variant palmaris longus muscle, an unknown variation of the flexor carpi ulnaris muscle and a persistent median artery were discovered during routine anatomical dissection. The anatomical aspects of these variations have been discussed in detail. We also review the clinical literature and presented their possible clinical implications.
