A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture . [ 1 ]
A direct hit to the collarbone can also cause a break. In most cases, the direct hit occurs from the joint side towards the body side of the bone. The muscles involved in clavicle fractures include the deltoid, trapezius, subclavius, sternocleidomastoid, and sternohyoid. The ligaments involved include the conoid ligament and trapezoid ligament.
The muscle damage is most usually caused by a crush injury, strenuous exercise, medications, or a substance use disorder. [3] Other causes include infections , electrical injury , heat stroke , prolonged immobilization, lack of blood flow to a limb , or snake bites [ 3 ] as well as intense or prolonged exercise, particularly in hot conditions ...
The cancellous bone forms via two ossification centres, one medial and one lateral, which fuse later on. The compact forms as the layer of fascia covering the bone stimulate the ossification of adjacent tissue. The resulting compact bone is known as a periosteal collar. The collarbone has a medullary cavity (marrow cavity) in its medial two ...
However, the swelling increases the intracellular pressure beyond normal limits. As the pressure builds in the muscle tissue, the surrounding tissue is crushed against the underlying tissue and bone. [14] This is known as compartment syndrome which leads to greater death of the surrounding muscle tissue around the injury. [14]
The most devastating systemic effects can occur when the crushing pressure is suddenly released, without proper preparation of the patient, causing reperfusion syndrome. In addition to tissue directly suffering the crush mechanism, tissue is then subjected to sudden reoxygenation in the limbs and extremities.
Buckle fractures are an incomplete break in the bone that involves the cortex (outside) of the bone. Buckle fractures are stable and are the most common type. [4] Greenstick fractures are a bone that is broken only on one side and the bone bows to the other side. [4] Greenstick fractures are unstable and often occur in younger children.
Musculoskeletal injuries can affect any part of the human body including; bones, joints, cartilages, ligaments, tendons, muscles, and other soft tissues. [1] Symptoms include mild to severe aches, low back pain, numbness, tingling, atrophy and weakness. [1] [2] These injuries are a result of repetitive motions and actions over a period of time. [6]
