Proximal humerus fractures account for approximately 4-7% of all fractures in adults. [11] [8] It is the most common fracture of the humerus, as well as the most common fracture at the shoulder girdle. [11] [8] They are more common in women than men, and occur more often in older adults.
A humerus fracture is a break of the humerus bone in the upper arm. [1] Symptoms may include pain, swelling, and bruising. [1] There may be a decreased ability to move the arm and the person may present holding their elbow. [2] Complications may include injury to an artery or nerve, and compartment syndrome. [2]
An open fracture (or compound fracture) is a bone fracture where the broken bone breaks through the skin. [2] 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 ...
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]
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 ...
A cubitus varus deformity is more cosmetic than limiting of any function, [4] however internal rotation of the radius over the ulna may be limited due to the overgrowth of the humerus. This may be noticeable during an activity such as using a computer mouse. [citation needed]
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.
