This condition typically occurs with age and results from the wearing down of the cartilage at the end of a bone.
The purpose is also for the education on equipment use to compensate for some loss of function during the healing process and for the practice of daily activities which may be more difficult to do since the injury and/or surgery. There are some important terms to know with regard to the anatomy of your humerus:In addition to the areas mentioned above, the humerus is made up of other parts, too.

Each of these procedures is typically followed by placement of a cast or sling to protect the arm and prevent re-injury while the patient slowly resumes some daily activities.
The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The nutrient arteries enter the humerus through this foramen. Many powerful muscles that manipulate the upper arm at the shoulder and the forearm at the elbow are anchored to the humerus.
On the posterior side of the humerus, a small cavity known as the olecranon fossa allows the tip of the ulna, known as the olecranon, to lock into the humerus and prevent the extension of the elbow beyond 180 degrees.The humerus is classified structurally as a long bone because it is considerably longer than it is wide. Mid-shaft or middle: A break that occurs in the shaft or body of your humerus. The common tendon of the extensor muscles of the forearm and the The Medial supracondylar crest forms the sharp medial border of the distal humerus continuing superiorly from the medial epicondyle.
The lateral epicondyle is the non-articular lateral bulge of bone located superior and lateral to the capitulum. The shape of the joint between the capitulum and radius allows the forearm and hand to rotate and bend at the elbow while the ulna forms a tight hinge with the trochlea. spiral groove: groove in the bone for the radial nerve.
This is a common condition in which the tendons surrounding the humerus or the humerus itself becomes inflamed and irritated. In some locations, such as in the humerus or around the knee, almost all bone tumors may be found.
The Anterolateral Surface is the area between the lateral border of the humerus to the line drawn as a continuation of the crest of the greater tubercle.
The humerus is most frequently fractured as the result of a fall or motor vehicle crash. The nutrient foramen of the humerus is located in the anteromedial surface of the humerus. The humerus is the both the largest bone in the arm and the only bone in the upper arm. Fractures of the humerus are relatively common and can occur at any location on the humerus. Unsubscribe at any time.Below the deltoid tuberosity, the humerus gradually widens, doubling its width as it approaches the elbow. This can be age-related or due to overuse such as in a job with repetitive motions or sports that require frequent forceful movement of the arm. Movement of the humerus is essential to all of the varied activities of the arm, such as throwing, lifting, and writing.At its proximal end, the humerus forms a smooth, spherical structure known as the head of the humerus.Thank you for subscribing! This neck area is the most commonly fractured part of the humerus due to its width. This is located posteroinferior to the deltoid tuberosity. Distal: A break that happens at the end of … The coronoid fossa is smaller than the olecranon fossa and receives the coronoid process of the ulna during maximum flexion of the elbow. At the proximal end, ... An impact fracture, often the result of a humeral fracture, is where one bone fragment is driven into the spongy bone of another bone fragment. Many powerful muscles that manipulate the upper arm at the shoulder and the forearm at the elbow are anchored to the humerus.
The lesser tubercle provides insertion to The intertubercular groove or also known as the bicipital sulcus is a deep groove that begins between the two tubercles and extends longitudinally down the proximal shaft of the humerus. The Lateral Supracondylar crest forms the sharp lateral border of the distal humerus continuing superiorly from the lateral epicondyle.At the shoulder, the head of the humerus articulates with the glenoid fossa of the The four muscles of supraspinatus, infraspinatus, teres minor and subscapularis form a musculo-ligamentous girdle called the During embryonic development, the humerus is one of the first structures to ossify, beginning with the first "Humeral" redirects here.
You must consult your own medical professional. Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. Like all long bones, the humerus is hollow in the middle of its shaft and is reinforced at the ends by small columns of spongy bone known as trabeculae. The patient is able to complete light exercises with therapist supervision around four weeks after surgery. Unlike other bones, the hyoid is only distantly articulated to other bones by muscles or ligaments. Many powerful muscles that manipulate the upper arm at the shoulder and the forearm at the elbow are anchored to the humerus.
The shoulder joint, comprised in part by the humerus bone, is considered a ball-and-socket joint. At the elbow, it connects primarily to the ulna, as … Your doctor can help diagnose what may be causing your pain and develop a treatment plan.© 2005-2020 Healthline Media a Red Ventures Company. The humerus is the largest bone in the entire upper extremity.
Therapy programs provided by an occupational or physical therapist will vary depending on each individual’s demonstrated deficits. The corresponding anatomy must allow for this movement, which also makes this joint quite vulnerable to injury when improper movements and forces are present. These are movement and support. The humerus is a long bone in the arm that runs from the shoulder to the elbow also known as adele. Read our Medically reviewed by Elizabeth Molina Ortiz, MD, MPH
