Humerus condylar fracture incision and internal fixation

There are 4 to 5 ossification centers and epiphyseal lines at the lower end of the humerus in childhood, appearing at different ages [Figure 44-40]. In addition, there is a coronal fossa in the front and a gargoyle fossa in the back. The bone scaffold of the palate is relatively weak and prone to fracture. Due to the attachment of the extensor muscle group of the humerus and the flexor muscle group of the medial condyle, it is very easy for the zygomatic fracture to reverse and shift; and it is difficult to reset manually after the shift; Pull and shift again. In addition, zygomatic fractures often involve the articular surface and epiphysis. If proper treatment is not given in time, it can not only affect the extension and flexion function of the joint, but also affect the development of epiphysis and growth deformities. Common humeral condyle fractures include humeral epicondylar fractures and medial epicondyle fractures. Fractures of the medial epicondyle are prone to ulnar nerve injury, and attention should be paid during examination. These two types of patellar fractures are mostly cartilage. X-ray films are not developed and are sometimes easily overlooked [Figure 1].
