Overview
If left untreated, most of patients with Osteoporosis may progress to develop fracture. With appropriate and timely usage of medications along with calcium and/or vitamin D supplementation, the outcome of osteoporosis is usually good. Apart from risk of death and other complications, osteoporotic fractures are associated with a reduced quality of life due to immobility; emotional problems may also raised as a consequence. As studies suggested, the impact of osteoporosis and also osteoporotic fractures on public life would be worse than lots of life threatening diseases; especially with aging.
Natural history, complications, and prognosis
Natural history
- Typically, symptoms of osteoporosis are developed in the sixth decade of life. The risk of getting osteoporosis is increased proportionately with age.
- Researchers have shown that relationship between lowering bone density of spine and age is not linear, but quadratic; in which bone loss tailing off when age raised. During the first years of post-menopausal period, women would have a fast decrease in bone density of spine by rate of 3.12% annually; then the rate slowed down to 0.02% per square age increased.[1]
- However, Guthrie also mentioned that in first 3 years after menopause, the rate of decreasing bone density increased annually; then with years past from menopause, the rate of bone loss will slow down.[2]
- One another major factor that directly impact on changing BMD is body weight; women with heavier weight and also higher body mass index (BMI) may have more change in their BMD in both hip and lumbar spine, during the time.
- Surprisingly, the bone site is an important factor to determine the measure of bone loss. The studies have found that magnitude of bone density loss is higher at spine (-3.12% annually) compared to femoral neck (1.67% annually). The main proposed theory for the phenomenon is "different effect of estrogen deficiency on different bone sites". On the other hand, it may show the preventive effect of weight bearing on hip osteoporosis.[1]
- With appropriate and timely usage of medications along with calcium and/or vitamin D supplementation, the outcome of osteoporosis is usually good. But if the disease left untreated, or not favorably treated, the clinical consequence would be fracture and the morbidity that happen thereafter. The main type of fracture that influence the quality of life more and happened earlier, is vertebral fracture.[3]
Complications
- The major probable complications of osteoporosis include:
- Fractures: hip and lumbar spine are among the most frequent sites of fracture.
- Deep venous thrombosis (DVT): It can be caused by prolonged immobility.
- Kyphosis (Dowager's hump): The main reason could be decreasing the height of anterior aspect of cervical vertebrae body (wedge shape).
- Restrictive lung disease: Because of decreasing thoracic space, due to vertebrae body compression.
- Apart from risk of death and other complications, osteoporotic fractures are associated with a reduced quality of life due to immobility; emotional problems may also raised as a consequence.[4]
Fracture risk
Fracture risk categories in glucocorticoid-treated patients is as table below.[5]
Adults ≥ 40 years of age | Adults <40 years of age | |
---|---|---|
High fracture risk |
|
|
Moderate fracture risk |
|
or and
|
Low fracture risk |
|
|
Prognosis
- If the bone mass density loss is identified early and the appropriate medicine begin as soon as possible, the prognosis of osteoporosis would be good.
- The most important issue to identify the osteoporosis prognosis is fractures; mainly affected by two factors include advancing age and low BMD. The relation is consist of having about 2-fold increase in risk of various fractures following every SD lowering of BMD or 5 years age advance.[6]
- When the fracture risk of lifetime at age 60 become adjusted upon death rate, it may be 44% for woman and 25% for men. The lifetime fracture risk for hip is 9% in women and 4% in men. The researchers suggest that lifetime fracture risk of hip in 60 years old women is 1 in 7 (15%); which is higher than estimated lifetime risk of breast cancer (9.3%). Similarly, fracture risk of hip and vertebrae in men (15%) is totally noticeable along with their prostate cancer risk. This means that the impact of osteoporosis and also osteoporotic fractures on public life would be worse than lots of life threatening diseases; especially with aging.[7]
