These structures are superimposed in a true lateral position of the elbow. Humeri is a long bone in the arm that runs from the shoulder to the elbow.

The humerus ˈhjuːmərəs plural.

Distal humerus anatomy. The elbow consists of portions of all three bones. The most distal part of the lateral column is the capitellum and that of the medial column is the nonarticular medial epicondyle. Located more medially and articulates with the ulna.

In the child the distal humerus is an osteochondral block of roughly triangular shape attached to the distal humeral diaphysis. The distal humerus is the lower end of the humerus. Distal humerus refers to the portion of the humerus bone in the upper arm that is farthest from the trunk of the body and nearest to the elbow joint.

Open fractures Infection Compartment syndrome3. The treatment of fractures of the distal humerus may be associated with high rates of complications such as malunion nonunion infection and nerve injuries. Nerve injuries are among the most dreaded complications by orthopedists for both the consequent functional loss for the patient and the liability implications for the surgeon.

Terms in this set 10 Trochlea. The base of the triangle comprises the transverse condylar mass. It connects the scapula and the two bones of the lower arm the.

The ulnar nerve runs initially in the anterior compartment of the arm and goes posteriorly through the medial intermuscular septum at an average distance of about 68 cm proximal to the medial epicondyle with a range of between 5 and 11 cm 4 5. A novel anatomy based radiographic assessment Iatrogenic nerve injury during fracture surgery of the upper arm is a well-known complication. Located on the lateral aspect and articulates with the head of the radius.

A term of relative location distal is used in anatomy in opposition to the term proximal The distal humerus then is the far or lower end of the bone while the proximal humerus is the end. The Humerus is the largest bone of the upper limb and it has two ends and a shaft. Prevention of this type of injuries would be of great value.

The distal humerus is the lower end of the humerus upper arm bone. The anatomy of the ulnar nerve is extremely variable in its course in the distal part of the humerus. This mass is composed of the lateral epicondyle the capitellum the trochlea and the medial epicondyle.

The humerus bone consists of several parts that allow the upper arm hand and elbow to move in different. At the distal end the humerus articulates with the head of the radius and the trochlear notch of the ulna forming the elbow joint. Anatomy of Humerus.

Right The major nerves and ligaments of the elbow are highlighted. Like other long bones the humerus has three main parts - a proximal end a shaft and a distal end. The distal end is irregular in shape.

Distal Region of Humerus The lower end of the humerus is the distal humerus containing two joint-forming processes the capitulum and the trochlea. The distal humerus consists of two columns of medial and lateral epicondylar ridges located at the distal humeral metaphysis and a central articulating axis trochlea. The shaft connects both the proximal and distal ends.

Distal humerus may be conceptualized as medial and lateral columns each of which is roughly triangular in shape and composed of an epicondyle or the nonarticulating terminal of the supracondylar ridge and a condyle which is the articulating unit of the distal humerus Fig. The humerus location is in the upper arm between the shoulder joint and elbow joint. The course of the radial nerve in the distal humerus.

All of these parts have important anatomical landmarks. Towards the center of the arm the trochlea tightly hinges with the ulna of the forearm forming half of the elbow joint. The proximal end is round and has an articular head.
