Clavicle bone Rating:
The clavicle, also known as the collarbone, is a long, slender bone that is located in the upper part of the human body, connecting the shoulder blade to the sternum. The clavicle plays a vital role in the movement and stability of the shoulder and upper limb.
The clavicle has a S-shaped curvature and is slightly curved outward at its ends. It is the only bone in the body that lies horizontally, and it acts as a strut to support the weight of the upper limb and protect the underlying structures, such as the brachial plexus and subclavian vessels.
The clavicle is a highly mobile bone that allows for a wide range of movements in the shoulder joint. It also helps to distribute the forces generated during arm movement and acts as a pivot point for the shoulder blade. The clavicle also plays a role in maintaining proper posture by keeping the shoulders and upper limb in their proper position.
Despite its importance, the clavicle is also one of the most commonly fractured bones in the body, due to its exposed position and the high amount of stress it experiences. Common causes of clavicle fractures include falls, sports injuries, and car accidents. Treatment for a clavicle fracture typically involves immobilization with a sling or splint, followed by physical therapy to restore range of motion and strength.
In conclusion, the clavicle is a vital bone in the human body that plays a crucial role in the movement and stability of the shoulder and upper limb. It is highly mobile and helps to distribute forces, maintain proper posture, and protect underlying structures. While it is prone to fractures, proper treatment can help to ensure a full recovery.
J Am Acad Orthop Surg 1997;5:11-18. Symptoms include pain localized specifically at the acromioclavicular joint at the top of the shoulder. Upward rotation of the scapula occurs when the arm moves both up and outward simultaneously. It acts as a site of attachment for the subclavius muscle. For example, if tight muscles or tissues are responsible, treatment may focus on stretching.
. The collarbone, also known as the clavicle, connects the shoulder blade to the breastbone. Fracture lines may be vertical, oblique, like a diagonal line on an x-ray, or spiral-shaped. Elevation and depression of the scapula assist with the movement of the entire shoulder capsule up and down, seen in motions such as shrugging of the shoulders. Complications Most broken collarbones heal without difficulty. After the bone has healed, you will be able to gradually return to your normal activities.
A person is likely to feel annoyed by the hardware as they feel it under a bra strap, backpack strap, or seatbelt chest strap. Tumors of the lymphoid tissue such as lymphoma or leukemia also cause the lymph nodes to swell. Adults, especially those who are older, are more prone to falls that cause broken collarbones. Weak shoulder muscles can allow the clavicle to slide down, placing pressure on the nerves and blood vessels in the thoracic outlet. Persistent instability repeat dislocations of the shoulder usually requires surgery.
Broken Collarbone Symptoms, Diagnosis, Treatment, and Care
Then it rises again in older people as they lose bone strength with age. Another advantage for the very severe deformity is that it will eliminate pain if the end of the collarbone is rubbing the skin or muscle. Ice should be particularly applied after athletic activities — or if the joint is very sore, ice should be applied daily or as often as every two hours. A compound fracture occurs when the break damages other tissue and organs, and can lead to greater pain and a longer or more strenuous healing process. Arthroscopic surgery may also be performed to manage symptoms of acromioclavicular joint arthritis when other treatment methods have failed to relieve pain. Surgical Treatment If the broken ends of the bones have significantly shifted out of place, your doctor may recommend surgery.
The shoulder is the most mobile joint in the human body; however, the extreme range of its potential movements makes the shoulder joint susceptible to dislocation. Generally this may be described as upper chest swelling. The figure-of-8 splint is generally uncomfortable, difficult to wear nonstop for six or eight weeks and can result in skin problems and a smelly patient because it should not be removed to wash the armpit. These may include range-of-motion exercises and graduated weightlifting. Falls are a top cause of collarbone injuries.
Proximal Humerus Fractures Most fractures of the proximal humerus can be treated without surgery if the bone fragments are not shifted out of position displaced. Nonsurgical Treatment If the broken ends of the bones have not significantly shifted out of place, you may not need surgery. Broken collarbones are a common Who is most at risk for a collarbone injury? The inflammation might occur in conditions like bursitis and tendonitis. Surgery typically involves putting the broken pieces of bone back into position and preventing them from moving out of place until they are healed. When to See a Healthcare Provider If your collarbone popping is caused by trauma, see your healthcare provider. There is sclerosis of the medial end of the clavicle. Studies have shown that these fractures heal just as quickly and as well with a sling as with the figure-of-8 splint, so we recommend a sling in a majority of cases.
In: DeLee, Drez, and Miller's Orthopaedic Sports Medicine: Principles and Practice. Fractures of the collarbone are common. Often, patients will begin doing exercises for elbow motion immediately after the injury. Because the ball of the upper arm is larger than the socket of the shoulder, it is susceptible to injury. A group of ligaments that connect the humerus to the socket of the shoulder joint on the scapula to stabilize the shoulder and keep it from dislocating.
At the other end, the bone meets the shoulder area at a part of the shoulder blade scapula called the acromion. A direct hit to the shoulder in football or other contact sport can cause a collarbone fracture. Doctors are currently Broken collarbone in children Treatment for children Broken collarbones in children usually heal without surgery. After a clavicle fracture, it is common to lose some shoulder and arm strength. This numbness will become less noticeable with time.
