A supracondylar humerus fracture is a fracture of the overall upper part of the medial and lateral humeral condyles, while a medial epicondyle humerus is a fracture of a prominent bone structure on the medial side of the elbow joint. Although these two fractures are relatively close to each other, they are two completely different locations. Both types of fractures are generally more common in children, with medial humeral epicondyle fractures being relatively easy to damage the ulnar nerve, while more severe supracondylar humeral fractures are prone to combined vascular and nerve injuries, making supracondylar humeral fractures, in comparison, more serious than medial humeral epicondyle fractures. However, the treatment method is basically the same. The fracture can be repositioned by manipulation, and after repositioning, external fixation in plaster is required. If there is neurovascular damage, the fracture should be repaired by incision and internal fixation.
