What is the Meaning & Definition of Pseudarthrosis

Pseudarthrosis is a complication that may occur during the process of consolidation of the fracture of a bone, consists in the absence in the formation of new bone in the reasonable time intervals, causing difficulty for the mobilization and pain and even deformity of the area in which it is located. After a fracture occur a series of changes intended to repair the bone. The process begins with the activation of platelets that are found in the hematoma, these cells are grouped to form a thrombus or blood clot that seeks to stop the bleeding, at the time that release of platelet growth factors that are capable of activating the bone cells and fibroblasts, which are cells that produce collagen will initiate the formation of osseous callus which is a refreshing tissue located between the ends of the bones and is remodeling until it closes the defect and mineralizes to acquire normal bone hardness. This process is carried out by phases and lasts for several weeks, it is estimated that a good corn has already been formed at 8 weeks, however bone manages to complete this whole process in an estimated period of two years. Pseudarthrosis in this process is not normally performed by which the ends of the bone fail to weld, remaining an ability to move between the two similar to what happens in a joint, there that the name of this condition is false joint or Pseudarthrosis. This disorder is common in children and when fractures are nondisplaced since in both cases there are in practice less patient care since its evolution is usually more favorable. Most affected bones are the bones as the humerus, femur and tibia. Other factors that can cause this disorder are open fractures in which there is an added infection, bad immobilization, circulatory disorders, local to that commit the local supply of nutrients, malnutrition and deficiencies of vitamins and minerals, necrosis of the bone and the presence of soft tissue between the ends of the bones that interfere with the formation of the callus. The correction of this disorder is usually surgical, in addition to the basic problem that gave origin, many times it's worth placing a graft of bone tissue from the patient obtained from other bones, especially of the hip, followed by a good immobilization after surgery.
