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.
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]
A fracture in this area is most likely to cause damage to the axillary nerve and posterior circumflex humeral artery. Damage to the axillary nerve affects function of the teres minor and deltoid muscles, resulting in loss of abduction of arm (from 15-90 degrees), weak flexion, extension, and rotation of shoulder as well as loss of sensation of ...

At the midshaft of the humerus, the radial nerve travels from the posterior to the anterior aspect of the bone in the spiral groove. A fracture of the humerus in this region can result in radial nerve injury. The ulnar nerve lies at the distal end of the humerus near the elbow. When struck, it can cause a distinct tingling sensation, and ...
A bone fracture may be the result of high force impact or stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, osteopenia, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture. [3] Most bone fractures require urgent medical ...
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 supracondylar humerus fracture is a fracture of the distal humerus just above the elbow joint. The fracture is usually transverse or oblique and above the medial and lateral condyles and epicondyles. This fracture pattern is relatively rare in adults, but is the most common type of elbow fracture in children. [1]
