A proximal humerus fracture is a break of the upper part of the bone of the arm . [3] Symptoms include pain, swelling, and a decreased ability to move the shoulder . [ 1 ] Complications may include axillary nerve or axillary artery injury.
In patients younger than 12, proximal humerus fractures can be visualized due to the changes at the bone surface. [15] Because bone tumors can appear at this location, X-ray imaging is necessary following a fracture diagnosis. The standard procedure is the shoulder-SAFE algorithm. [15]
Proximal fractures are classified into one of four types of fractures based on the displacement of the greater tubercle, the lesser tubercle, the surgical neck, and the anatomical neck, which are the four parts of the proximal humerus, with fracture displacement being defined as at least one centimeter of separation or an angulation greater ...
The native humerus and scapula bones are prepared using precise machining to accommodate their respective implants. At the end of the procedure, the subscapularis muscle is typically repaired, although some surgeons advocate not repairing this muscle due to the excess tension placed on it by the altered mechanics of the reverse shoulder design.
The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...

When the humerus is driven from the glenoid cavity, its relatively soft head impacts against the anterior edge of the glenoid. The result is a divot or flattening in the posterolateral aspect of the humeral head, usually opposite the coracoid process. The mechanism which leads to shoulder dislocation is usually traumatic but can vary ...
Injury of axillary nerve (axillary neuropathy) is a condition that can be associated with a surgical neck of the humerus fracture.. It can also be associated with a dislocated shoulder [1] or with traction injury to the nerve, which may be caused by over-aggressive stretching or blunt trauma that does not result in fracture or dislocation.
