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.
This nerve is the most commonly injured nerve in proximal humerus fractures due to its location close to the proximal humerus. [12] Muscles that attach to the proximal humerus and can cause a deforming force on fracture fragments include the pectoralis major, the deltoid, and the rotator cuff muscles. [11]
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. [24]
Among proximal fractures, 80% are one-part, 10% are two-part, and the remaining 10% are three- and four-part. [22] The most common location of proximal fractures is at the surgical neck of the humerus. [3] Incidence of proximal fractures increases with age, with about 75% of cases occurring among people over the age of 60. [11]

Buck's traction, involving skin traction. It is widely used for femoral fractures, low back pain, acetabular fractures and hip fractures. [2] Skin traction rarely causes fracture reduction, but reduces pain and maintains the length of the bone.

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 ...
