Introduction/Definition
Arthrosis (joint wear and tear) of the ankle describes a degenerative (wear-related) change in the upper ankle joint, which usually occurs after a previous illness or due to overloading. Due to the heavy strain on the upper ankle joint, osteoarthritis is a very common disease, which can, however, be very well treated conservatively at the beginning.
ICD/GdB
The ICD classification is the so-called “International Statistical Classification of Diseases and Related Health Problems”. It serves to classify health impairments in the health care system and is used in Germany, among other countries. In the ICD Classification, each disease is assigned its own number and number combination.
Ankle joint arthrosis can be found under the heading of “other arthrosis” and is specifically numbered M19. 07. GdB stands for “degree of disability” and refers to the classification of the impairment that can be caused by different diseases.
The grading is done on a table up to 100 in steps of 10. Depending on the extent of the impairment, different numbers of points are awarded. A value of 50 and higher is a severe impairment. Depending on the extent of the disease and individual impairment, ankle arthrosis can cause a GdB of 0 to 40. The GdB is determined by a medical expert.
Structure/Pathogenesis
The upper ankle joint consists of three communicating joint surfaces: To prevent these bone ends from rubbing against each other without protection, there is a layer of cartilage on each bone, which protects the bones from overloading and degeneration. Over the years, this layer of cartilage wears away increasingly. The factors that cause the cartilage layer to deteriorate much faster and the ends of the bones to rub against each other without protection include
- The end of the fibula,
- End of the shin bone (tibia)
- And the talus.
- Heavy loads,
- Inflammations
- Or previous injuries.
