The most notable structure located on the medial aspect of the elbow is the cubital tunnel, through which the ulnar nerve passes. The walls creating the tunnel include the olecranon and the medial epicondyle, while the joint capsule of the elbow and the transverse and posterior bands of the medial ulnar collateral ligament form the floor, and finally the roof is comprised of the fascia of the flexor carpi ulnaris muscle and Osborne’s band, and referred to as Osborne's fascia. Due to its location and function, Osborne’s fascia is of significance predominantly due to its potential to compress the ulnar nerve in the elbow.
位于肘部内侧最显著的结构是尺神经沟，尺神经从中穿过。构成该神经沟的壁包括尺骨鹰嘴和内上髁，而肘关节囊以及尺侧副韧带的横束和后束构成其底部，最后其顶部由尺侧腕屈肌筋膜和奥斯本氏韧带组成，也被称为奥斯本氏筋膜。由于其位置和功能，奥斯本氏筋膜主要因其有可能在肘部压迫尺神经而具有重要意义。
