What is pseudoarthrosis?

What Does pseudoarthrosis Mean

Pseudo is a compositional element of language that is used to name that which is an imitation or a copy and which, for that reason, is not original . Osteoarthritis , meanwhile, is a degenerative disorder that affects the joints.

It is known as pseudoarthrosis , therefore, a pathology that presents characteristics similar to osteoarthritis. Pseudoarthrosis occurs when, after a fracture , the bone segments are not repaired correctly : in this way, there is a false union in the bone that causes mobility, as if it were a joint.

Pseudoarthrosis typically affects adults after trauma or surgery . In certain cases, pseudarthrosis can affect children who suffer a spontaneous fracture , receiving the name of congenital pseudarthrosis .
Pseudoarthrosis is usually detected when, after the normal period of reestablishment after a fracture or surgery, the patient does not regain normal mobility. The treatment will contemplate a surgical intervention whose characteristics will vary according to the presence, or not, of an infection .
Among the most common cases of pseudoarthrosis is the one that affects the humerus and is identified by the fact that its bone consolidation cannot be defined and established after a period of four to six months.
When pseudoarthrosis involves the lack of formation of a callus, it is likely to cause pain to the person since the ends of the bone will present points. In these cases, we speak of atrophic pseudoarthrosis . The hypertrophic nonunion occurs when you try to create the callus bone fracture repair, but to no avail.
If the nonunion includes an infectious focus, the infected bone must be removed and replaced. On the other hand, when no infection is registered, surgery will tend to repair the same bone fragment.
It must be stated that, in recent years, much progress has been made in the treatment of atrophic nonunion. Specifically, in some hospitals, such as the famous Teknon Medical Center in Barcelona, ​​work is being done on this with stem cells.
Specifically, the Regenerative Therapy Unit of said health center is investigating the use of those cells in the treatments related to the aforementioned type of pseudoarthrosis. Exactly what they do is use stem cells from the patient's bone marrow to proceed to use them as grafts and thus regenerate the relevant bone area.
At the moment it is only an investigation, but just over 90% of the 40 cases that have been treated with this system have been successful.

In addition to all the above, it must be emphasized that pseudoarthrosis can be classified into several types according to its severity and evolution. Thus, for example, if the bone loss is less than 1 centimeter, it can be mobile or rigid and the latter in turn is divided into without deformity or with deformity.
In the event that said bone loss is greater than 1 centimeter, we would have to speak of three types of pseudoarthrosis: bone defect, shortening and shortening with defect.
