Proximal humerus fractures in children can commonly be treated non-operatively due to the large amount of bone growth that occurs at the proximal humerus. [16] In older children where there is less time for bone remodeling, surgery may be indicated more frequently.
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.
One example of a commonly used regional anesthetic is an interscalene brachial plexus block and it has been used in a number of shoulder procedures including instability repairs, proximal humeral prosthetic replacements, total shoulder arthroplasties, anterior acromioplasties, rotator cuff repairs, and operative treatment of humeral fractures.

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.

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 ...
A pathologic fracture is a bone fracture caused by weakness of the bone structure that leads to decrease mechanical resistance to normal mechanical loads. [1] This process is most commonly due to osteoporosis , but may also be due to other pathologies such as cancer , infection (such as osteomyelitis ), inherited bone disorders, or a bone cyst .
