The premise that bones grow and remodel throughout life to adapt to their mechanical environment is often called Wolff’s law. Wolff’s law, however, is not always true, and in fact comprises a variety of different processes that are best considered separately.

Do bones get stronger under pressure?
Just like muscle, human bone grows and strengthens under pressure, and weakens when barely put to use.
Who developed Wolffs law?
This law was developed in the 19th century by German surgeon and anatomist Julius Wolff. He posited that if the load under which a bone is placed is increased, the bone naturally reconstructs itself to become stronger and withstand the additional strain.
What is Wolff’s law concerned with?
Wolff’s Law states that bone grows and remodels in response to the forces that are placed upon it in a healthy person. After an injury to a bone, placing specific stress in specific directions to the bone can help it remodel and become normal, healthy bone again.
What are some potential medical implications of Wolffs law?
Wolff’s law is clinically apparent by the formation of osteophytes around an arthritic joint (increased stress causes hypertrophy of the bone) and under rigid internal fixation plates (bone atrophy). It also manifests in osteoporosis of bedridden, non-functional or neurologically impaired patients with atrophic bone.
Can you lift weights if you have osteoporosis?
If you have osteoporosis in the hips, there is no specific restriction on the amount of weight lifted or types of movement. But people with osteoporosis in any area should ensure that their activities don’t increase the risk of falling.
Are teeth bones?
Even though teeth and bones seem very similar, they are actually different. Teeth are not bones. Yes, both are white in color and they do indeed store calcium, but that’s where their similarities end.
Does Wolff’s law apply to cartilage?
Wolff’s law theorizes that repetitive loading of bone will cause adaptive responses enabling the bone to better cope with these loads. Accumulating evidence at the knee suggests that expanding articular bone surface area is driven by mechanical stimulation and is a strong predictor of articular cartilage loss.
What is hueter Volkmann’s law?
The ‘Hueter-Volkmann Law’ proposes that growth is retarded by increased mechanical compression, and accelerated by reduced loading in comparison with normal values.
Wolff’s Law states that your bones will adapt based on the stress or demands placed on them. When you work your muscles, they put stress on your bones. In response, your bone tissue remodels and becomes stronger.
Is bone resorption good or bad?
This is a natural process that’s important for your health and wellbeing. But when resorption happens at a higher rate than it can be replaced, it can lead to a decrease in your bone mass and put you at higher risk for fractures and breakage.
What bones are most vulnerable to osteoporosis?
Although all bones can be affected by the disease, the bones of the spine, hip, and wrist are most likely to break. In older people, hip fractures can be particularly dangerous.
Which of the following best describes Wolff’s law?
Which of the following describes Wolff’s law? Bones form according to the stresses placed upon them. During bone repair, what cells are responsible for producing collagen fibers that span the area between bone pieces?
What are two possible mechanisms that could account for Wolff’s law?
These include, but are not limited to, an expanding subchondral bone cross-sectional area, changes in bone mass, and remodeling of the trabeculae network.
What risk factors come with osteoporosis?
Factors that will increase the risk of developing osteoporosis are:
- Female gender, Caucasian or Asian race, thin and small body frames, and a family history of osteoporosis.
- Cigarette smoking, excessive alcohol and caffeine consumption, lack of exercise, and a diet low in calcium.
- Poor nutrition and poor general health.
Why is osteoporosis bad?
Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine.
