Proximal humerus fracture in adults. It is the most common fracture of the humerus, as well as the most common fracture at the shoulder girdle. They are more common in women than men, and occur more often in older adults. The average age of people who sustain a proximal humerus fracture is 63–66 years. Proximal humerus fracture A proximal humerus fracture is a break of the upper part of the bone of the arm (humerus). Symptoms include pain, swelling, and a decreased ability to move the shoulder. Complications may include axillary nerve or axillary artery injury. The cause is generally a fall onto
Humerus the ulna. The axillary nerve is located at the proximal end, against the shoulder girdle. Dislocation of the humerus's glenohumeral joint has the potential to injure the axillary nerve or the axillary artery. Signs and symptoms of this dislocation include a loss of the normal shoulder contour and a palpable depression under the acromion. The radial nerve follows the humerus closely. 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
