Anatomical Features and Clinical Importance of Cubital Fossa

Objective: Healthcare professionals in healthcare practice frequently use the cubital fossa. Any problem occurring in this area can affect the patient’s quality of life and cause severe financial and moral penalties for healthcare professionals. While previous studies often examine structures unilaterally, we aimed to examine this area with a holistic approach. Materials and Methods: Dissection of the upper extremities of 30 adult male cadavers was performed by fixing them with 10% formalin. Upper extremity superficial vein course types, median nerve (MN), and brachial artery courses and branches were checked and measured. Results: Positive correlations have been identified between the arm, forearm, midline, and biceps aponeurosis in cadaver upper extremities. It was observed that four atypical vein courses, the MN root junctions were in the arm, the musculocutaneous nerve branched into the MN, the proximal branch of the MN was above the midline, the Struthers’ ligament was present, the MN did not pass through the head of the pronator teres (PT), the MN passed under the ulnar head of the PT muscle, which appeared as a fibrous band after piercing the head of the humerus, and the brachioradial artery (radial artery with high origin) was present. Conclusions: This study distinguishes itself from previous research by presenting a comprehensive compilation of measurement results and anatomical variations. We believe that the data provided are crucial for optimizing surgical approaches and diagnosing issues related to the structures within this region.
