It is vulnerable to injury with fractures of the humeral shaft as it lies in very close proximity to the bone (it descends within the spiral groove on the posterior aspect of the humerus). Characteristic findings following injury will be as a result of radial nerve palsy (e.g. weakness of wrist/finger extension and sensory loss over the dorsum ...
Most proximal humerus fractures are stable and can be treated without surgery. [8] Typical non-operative treatment consists of shoulder immobilization with a sling. Close follow-up and weekly x-rays are recommended in order to ensure that the fracture is healing and maintaining good alignment.
The cause of a humerus fracture is usually physical trauma such as a fall. [1] Other causes include conditions such as cancer in the bone. [2] Types include proximal humeral fractures, humeral shaft fractures, and distal humeral fractures. [1] [2] Diagnosis is generally confirmed by X-rays. [2]
This fracture pattern is relatively rare in adults, but is the most common type of elbow fracture in children. [1] In children, many of these fractures are non-displaced and can be treated with casting. Some are angulated or displaced and are best treated with surgery.
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.

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 ...
Treatments may include medication, not walking on the affected leg, stretching, and surgery. [1] Most of the time surgery is eventually required and may include core decompression, osteotomy, bone grafts, or joint replacement. [1] About 15,000 cases occur per year in the United States. [4] People 30 to 50 years old are most commonly affected. [3]
The name funny bone could be from a play on the words humorous and humerus, the bone on which the medial epicondyle is located, [2] although according to the Oxford English Dictionary, it may refer to "the peculiar sensation experienced when it is struck". [3] Medial epicondyle fracture of the humerus are common when falling onto an ...
