Cubital tunnel syndrome results from compression of the ulnar nerve as it passes through the cubital tunnel at the elbow. That tunnel is formed between the medial epicondyle of the humerus (the inner elbow bump) and the olecranon process of the ulna (the back tip of the elbow), with the roof provided by soft tissue structures like Osborne’s ligament. So the nerve is most vulnerable where the space is specifically between the medial epicondyle and the olecranon. The other pairings describe spaces on different sides of the elbow or near the radioulnar joints, which do not constitute the cubital tunnel where the ulnar nerve travels.
