Distal Humerus Anatomy

Trochlea articulates with sigmoid notch. Allows for flexion and extension.

The proximal and distal ends of the humerus are cancellous bone with a superficial layer of compact bone.

Distal humerus anatomy. The base of the triangle comprises the transverse condylar mass. It extends from your shoulder to your elbow where it joins with the ulna and radius bones of your forearm. The top of the arm bone is called the proximal humerus and the bottom of the bone is called the distal humerus.

A fracture of the humerus in this region can result in radial nerve injury. Distal humerus fractures are traumatic injuries to the distal part. Muscles common flexors originate from medial epicondyle pronator teres.

At the midshaft of the humerus the radial nerve travels from the posterior to the anterior aspect of the bone in the spiral groove. The bones have moved out of place displaced fracture pieces of bone have punctured the skin open fracture because of the increased risk of infection open fractures are scheduled for surgery as soon as possible usually within hours. When struck it can cause a distinct tingling sensation and sometimes a significant amount of pain.

A humerus fracture refers to any break in this bone. The shaft is comprised of compact bone containing a medullary canal traversing its length. A fracture in this area can be very painful and make elbow motion difficult or impossible.

Osteology elbow is a hinged joint. This mass is composed of the lateral epicondyle the capitellum the trochlea and the medial epicondyle. Surgery is usually required for distal humerus fractures in which.

In the child the distal humerus is an osteochondral block of roughly triangular shape attached to the distal humeral diaphysis. The following nerves are located on the following aspects of the humerus. A distal humerus fracture is a break in the lower end of the upper arm bone humerus one of the three bones that come together to form the elbow joint.

A humerus fracture is an injury to the bone of the upper arm that connects the shoulder to the elbow. Humerus fractures are generally divided into three types of injuries based on the location of the fracture. The pain from a humerus fracture often extends to either your shoulder or elbow depending on where the break is and recovery may last several weeks.

Distal humerus fractures practice essentials. The ulnar nerve lies at the distal end of the humerus near the elbow. The incidence of fractures of the elbow joint is small compared with that.

Capitellum articulates with proximal radius allows for forearm rotation. The difficulty in treating complex distal humerus fractures lies in.
