Arthrosis, Osteoarthritis or Osteoarthrosis
Osteoarthritis is the same as osteoarthritis, osteoarthritis or degenerative joint disease. It accounts for around 40% of consultations with specialists in the musculoskeletal field, making it one of the most common musculoskeletal diseases.
Affects different types of joints:
Spine or spondyloarthrosis
Knee or gonioarthrosis
Coxofemoral joint, or coxarthrosis
Hand joints
Worse with age: Osteoarthritis and Degenerative Stenosis
It increases over the years, being uncommon before the age of 40 and more common after the age of 60. By the age of 75, 85% of people have radiological or clinical evidence of the disease, but only 30 to 50% of individuals have changes observed on x-rays. complain of chronic pain.
Osteoarthritis (arthrosis) is a disease characterized by the wear of articular cartilage and bone changes, including osteophytes, commonly known as “parrot beaks”.
In the spine, osteoarthritis can contribute to degenerative stenosis, so that osteophytes, which are bone proliferations, begin to reduce the space for the nerves and marrow.
Degenerative Stenosis
Osteoarthritis (arthrosis) occurs more in women than men. The pattern of presentation differs in terms of sex, for example in females, hands and knees, others in males, such as the coxofemoral joint (of the femur with the pelvis).
Types of Osteoarthritis (Arthrosis)
It can be divided into those without a known cause (so-called primary) or with a known cause (so-called secondary). The causes of this last form are numerous, from joint defects, such as knees with deviations in direction (valgus or varus), to changes in metabolism.
The involvement of heredity is important, especially in certain clinical presentations, such as nodules on the fingers, called Heberden's nodules (at the fingertip joint) or Bouchard's nodules (at the middle joint of the fingers).
Impact of the disease on society
The treatment and prevention of osteoarthritis is very important, as it can be demonstrated through social security data in Brazil, as it is responsible for 7.5% of all absences from work; it is the second disease among those that justify initial aid, with 7.5% of the total; it is also second in relation to sickness benefit (in extension) with 10.5%; it is the fourth to determine retirement (6.2%).
