Where is the most common fracture location of the proximal humerus?

The most frequently fractured site of the humerus especially in elderly is the surgical neck which is an area of constriction distal to the tuberosities.

Where is the humeral diaphysis?

The AO classification system defines the proximal and the distal segments of long bones by a square whose sides have the same length as the widest part of the epiphysis; the diaphysis is the remaining middle portion of the bone (Figure 22.1).

What is the proximal humeral diaphysis?

Proximal humeral fractures occur most commonly in older adults, and their incidence is increasing. Fractures of the humerus can occur proximally, in the shaft (diaphysis), or distally. The majority of both proximal and midshaft humeral fractures are nondisplaced and can be treated conservatively (ie, nonsurgically).

What is a diaphyseal humerus fracture?

Humeral shaft fractures are common fractures of the diaphysis of the humerus, which may be associated with radial nerve injury.

What is a 4 part fracture of proximal humerus?

The four parts are the humeral head, the greater tuberosity, the lesser tuberosity and the humeral shaft. Displacement is on a per-part basis. A fracture part is considered displaced if angulation exceeds 45 degrees, or if the fracture is displaced by more than 1 cm 1.

What is a proximal fracture of the humerus?

A proximal humerus fracture is a partial or complete break in the upper arm bone (humerus) near or in the shoulder. Anatomy and Symptoms. The proximal area of the humerus is the portion near the arm’s attachment to the body.

Where is the greater tubercle?

humerus
The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles – supraspinatus and infraspinatus. It is injured/fractured in a fall by either landing directly onto the side of your shoulder or landing with your arm outstretched.

How do you treat a proximal humerus fracture?

Proximal humerus fractures may be treated nonoperatively with an initial period of immobilization followed by early motion. Initial immobilization may be achieved with a sling, a shoulder immobilizer, or a sling with an accompanying swathe. These devices provide varying degrees of constraint.

How would you classify a fracture of the left humerus at the proximal Diaphysis?

The Neer classification for proximal humerus fractures is based on 4 fracture parts: the greater tuberosity, the lesser tuberosity, the humeral head, and the humeral shaft. If any of the 4 segments is separated by more than 1 cm from its neighbor or is angulated more than 45°, the fracture is said to be displaced.

What is a midshaft fracture?

A mid-shaft humerus fracture is a type of broken arm. The humerus is the bone in your upper arm, between your shoulder and elbow. It’s especially strong and is capped with the ball of the ball-and-socket shoulder joint. It also includes the hinge of the elbow joint on the bottom.

What is a 3 part proximal humerus fracture?

3-PART FRACTURE: This is when the proximal humerus is broken into three pieces, and there are then two fracture lines on x-ray. This most often involves the greater tuberosity and the surgical neck of the humerus.
