Back to index | 5 What are musculoskeletal conditions? The term ‘musculoskeletal conditions’ is often used to include a broad range of health conditions affecting the bones, joints, muscles and spine, as well as rarer autoimmune conditions such as lupus. In fact, musculoskeletal conditions comprise over 100 different diseases and syndromes that interfere with people’s ability to carry out their normal daily activities. Common symptoms include pain, stiffness and a loss of mobility and dexterity. Broadly speaking there are three groups of musculoskeletal conditions:6 Age Progression Prevalence Impact Main treatment Treatment location Risk factors Inflammatory Common.

The data UK have osteoporosis.12 currently available on specific conditions comes from several different sources (e.g. hospital records, national survey’s, statistical models, and registers) and doesn’t always cover the same time periods. Additionally, when people have more than one condition there is a risk of double counting • Over 300,000 fragility fractures or of people being missed from the data if arthritis is not recorded as their primary condition. As a result, you cannot simply add the estimates above together and have an accurate total of the number with arthritis or musculoskeletal conditions. For these reasons we currently rely on the Global occur each year.13 Burden of Disease study to provide us with an estimate of the total number of people with any musculoskeletal condition in the UK today.

Condition specific data Back to index | 19 Inflammatory conditions Axial spondyloarthritis (including ankylosing spondylitis) Axial spondyloarthritis (axSpA) is an umbrella term used to describe a spectrum of long-term (chronic) inflammatory conditions primarily affecting the spine and/or sacroiliac joints, resulting in the main symptom of chronic back pain. It includes both people who have the visible changes or damage of the sacroiliac joints as seen on x-ray (ankylosing spondylitis) as well as people who have the symptoms of chronic back pain without the classic changes or damage seen on ordinary x-rays of the sacroiliac joints (non-radiographic axSpA). Inflammation of the spinal joints and surrounding structures causes pain, stiffness and limitation in the flexibility of the back and causes new bone to grow at the sides of the vertebrae. Eventually the individual bones of the spine may link up and fuse. Non-radiographic axial spondyloarthritis progresses to ankylosing spondylitis at a rate of about 12% over 2 years.74 To understand more about the causes, diagnosis and treatment of ankylosing spondylitis download our information booklet.

Inflammatory conditions Back to index | 22 Gout Gout is a painful inflammatory condition, caused by the build-up of uric acid in the bloodstream. This is partly inherited, but lifestyle factors such as alcohol consumption, diet and obesity are major risk factors. High uric acid levels lead to crystals forming in the joints. These crystals can trigger sudden painful episodes of severe joint inflammation (‘attack’). If untreated these attacks get more common, spread to involve new joints and can cause long-term cartilage and bone damage.

Osteoarthritis results from a combination of the breakdown of the joint and the body’s attempted repair processes.

Muskuloskeletal pain Back to index | 36 Fibromyalgia Fibromyalgia is a long-term (chronic) condition causing many symptoms including widespread body pain and fatigue. It’s quite common – up to one person in every 25 people may be affected. The exact causes of fibromyalgia are still not known, but research suggests that there’s an interaction between physical, neurological and psychological factors. Fibromyalgia in itself doesn’t cause any lasting damage to the body’s tissues. However, it’s important to build up and maintain physical activity levels to avoid and address weakening of the muscles (deconditioning) which could lead to worsening pain and fatigue.

Condition specific data Back to index | 38 Osteoporosis & fragility fractures Osteoporosis means spongy (porous) bone. Everyone has some degree of bone loss as we get older, but the term osteoporosis is used only when the bones become quite fragile. When bone is affected by osteoporosis, the holes in the honeycomb structure become larger and the overall density is lower, which is why the bone is more likely to fracture.
