There's a place where you scream 'Oh my' when you bump your foot on a coffee table or a chair, right? That hard bone we call the 'shin' is called the tibia in medical science. This is a very important, very strong bone in our body. This bone makes a big contribution to everything we do, whether we stand, walk, run, or jump. So today, let's talk about our shin bone in a little more detail.
Simply put, what is Tibia?
The tibia is the bone in your shin. It is the second longest bone in our body. (The longest bone is the thigh bone, or `Femur`). The tibia is very important in supporting the weight of our body when we stand and walk. It is also the bone that supports many important muscles, tendons, nerves, and ligaments in our leg.
It is so strong that it usually requires a major impact, such as a serious accident, a fall from a height, or a car accident, to break it. If a bone is broken (fractured), surgery is often needed to set it and physical therapy to restore strength.
What are the main services that the tibia bone provides to our body?
The tibia bone performs several very important functions for our body.
- Body weight support: This bone helps support the weight of our entire body when we stand and walk.
- Keeping the body stable: This helps keep our body balanced and stable as we move, walk, and run.
- Coordination: The muscles, tendons, and ligaments in our knees and ankles act like a bridge connecting them to the rest of the body.
Tibia vs. Fibula - What is the difference between these two?
There are two main bones in our lower leg, below the knee. They are the tibia and the fibula. Many people confuse the two.
The tibia is the larger, stronger of the two bones. It is located on the inner side of the leg. The fibula is a smaller, thinner bone than the tibia. It is located on the outer side of the leg. The main difference is that the tibia is the one that bears the weight of our body. The fibula mainly provides structural support for the leg.
| Factor | Tibia | Fibula |
|---|---|---|
| Location | The large bone on the medial side of the lower leg. | The thin bone on the outer side (lateral) of the lower leg. |
| Size | Longer and thicker than the fibula bone. | Thinner and shorter than the tibia bone. |
| Main function | Weight-bearing is the main function of the body. | Mainly to provide structural support and stabilize the ankle joint. |
Appearance of the tibia bone and its parts
Although the tibia is a continuous bone, it has three main parts. While these names aren't important in everyday life, they can help you understand what doctors are talking about if you ever break a bone.
1. Proximal aspect: This is the part that forms the knee joint. It is slightly flat, like a shelf.
2. Shaft: This is the longest part of the bone. It is this part that gives our skull its shape.
3. Distal aspect: This is the part that forms the ankle joint.
There are other names that doctors use for these parts. For example, if you break your bone, your doctor may use names like `Medial malleolus`, `Anterior border` to tell you exactly where it broke.
Common diseases and conditions affecting the tibia bone
There are several major medical conditions that can affect our bones, and it is important to be aware of these.
| Medical condition | Description and symptoms |
|---|---|
| Tibia Fractures | This happens in a serious accident. The symptoms are:
|
| Osteoporosis | This causes the bones to become weak and break easily with even the slightest impact. Many people only find out they have the disease after they break a bone. There are no obvious symptoms at first. This risk is especially high for women and people over the age of 50. You can talk to your doctor about getting a bone density screening. |
| Osgood-Schlatter Disease | This is usually seen in growing children and young adults. The main symptom is pain in the upper part of the kneecap, just below the knee. It is sometimes called "jumper's knee." Characteristics:
|
| Paget's Disease of the Bone | This is a chronic bone disease. What happens is that the bones repeatedly break and regrow abnormally. This can cause the bones to become weak and deformed. This also most often affects people over the age of 50. Characteristics:
|
How to check the health of the tibia bone?
Doctors use various tests to check the health of your tibia or other bones.
The main test used to diagnose conditions like osteoporosis is a bone density test. Also called a `DEXA` or `DXA scan`, this uses low-level X-rays to measure how strong your bones are.
If you have been in an accident and suspect a fracture, your doctor may recommend one or more of the following tests:
- X-rays: The most basic test to see if there is a fracture, if so, where it is, and what type of fracture it is.
- MRI scan (Magnetic Resonance Imaging): This helps to see if there is any damage to the soft tissues around the bone, such as muscles, tendons, and ligaments.
- CT scan: This test is used to get a clearer, three-dimensional (3D) view of the fracture.
How do you keep your tibia bone healthy?
A good diet, exercise, and regular medical care can help keep your bones and your entire body healthy. Be especially mindful of these things to protect yourself from accidents.
- Wear seat belts: Always wear a seat belt when traveling in a vehicle.
- Use safety equipment: Wear appropriate safety equipment (e.g. helmet, knee pads) when playing sports or engaging in any risky activity.
- Protect the environment: Remove and tidy up any items that could cause you to slip and fall, as well as unnecessary belongings, at home and at work.
- Use the right equipment: Do not climb on chairs or tables to reach something above. Use a ladder or other suitable equipment for that.
- A lifestyle that strengthens bones: Eat foods rich in calcium and vitamin D. Engage in bone-strengthening exercises, such as weight-bearing exercises. Ask your doctor for more information about this.
- Use an aid if necessary: If you have difficulty walking or are at risk of falling frequently, don't be shy about using an aid such as a cane/walker.
We usually only think of our shinbone when we get hurt, but the tibia bone does a great job every time we stand or walk. Talk to your doctor about your risk of osteoporosis. Remember, everything you do to maintain your overall health also helps strengthen your bones.
Take-Home Message
- The tibia is the main, strong bone in your shin that bears the weight of your body.
- This is a very strong bone, so it usually only breaks with a major impact, such as a car accident.
- If you experience severe leg pain, swelling, deformity, or inability to walk after an accident, go to a hospital's Emergency Treatment Unit (ETU) immediately.
- Women over the age of 50 and those with a family history of osteoporosis should be especially concerned. Talk to your doctor about this.
- Good nutrition, regular exercise, and a safe lifestyle can keep all your bones, including your tibia, strong and healthy.
