Structure [ ] Upper extremity [ ] The upper or proximal extremity of the humerus consists of the bone's large rounded head joined to the body by a constricted portion called the neck, and two eminences, the greater and lesser tubercles. Head [ ] The head ( caput humeri), is nearly hemispherical in form. It is directed upward, medialward, and a little backward, and articulates with the Main article: The anatomical neck ( collum anatomicum) is obliquely directed, forming an obtuse angle with the body. It is best marked in the lower half of its circumference; in the upper half it is represented by a narrow groo...

The humerus is your upper arm bone. It’s connected to 13 muscles and helps you move your arm. When you injure your humerus, it’s likely the muscles and nerves attached to it will be damaged, too. If your bones are weakened by osteoporosis, you have an increased risk for fractures you might not even know about. Overview The humerus is the only bone in your upper arm. It runs from your shoulder to your elbow. What is the humerus? The humerus is your upper arm bone. Other than the bones in your leg, it’s the longest bone in your body. It’s a critical part of your ability to move your arm. Your humerus also supports lots of important muscles, If you experience a fractured (broken) humerus, you might need surgery to repair your bone and physical therapy to help you regain your strength and ability to move. Your humerus — like all bones — can be affected by osteoporosis. Because your humerus is connected to so many Anatomy Where is the humerus located? The humerus is the only bone in your upper arm. It runs from your shoulder to your elbow. What does the humerus look like? The humerus has a rounded end where it meets your shoulder, a long shaft in the middle and a flatter end that forms your elbow joint. The upper end has a ball shape that fits into your shoulder socket. Even though it’s one long bone, your humerus is made up of several parts. These include: Humerus proximal aspect The upper (proximal) end of your humerus connects to your shoulder joint. The proximal end (aspect...

The rhythm between the scapula and the humerus is a very important one for adequate shoulder function. Another important landmark is the anatomical neck, a slightly more narrow area just below the tubercles but above the shaft, which is the long part of the bone. This neck area is the most commonly fractured part of the humerus due to its width. Unfortunately, fracture at this point in the humerus can be damaging to children and adolescents, as this is also the location of the epiphyseal plate or growth plate. The shoulder joint, comprised in part by the humerus bone, is considered a ball-and-socket joint. This type of joint is the most versatile in the body, allowing for all degrees of motion. The corresponding anatomy must allow for this movement, which also makes this joint quite vulnerable to injury when improper movements and forces are present. As mentioned the growth plate is an integral yet sensitive part of the humerus. Birth defects, infection, and/or trauma can act on this growth plate to disrupt the growth process. This can lead to shortening or other deformities of the humerus. In situations such as these, medical intervention can assist with bone lengthening techniques to achieve a more normalized and functional appearance of the bone. Function The head of the humerus makes up a portion of the ball-and-socket shoulder joint. This area also serves as the insertion point for muscles which make up the shoulder girdle. This includes the long head of the biceps te...
