Pelvic bone, anatomy and health preservation
Bones of the pelvic girdle form a kind of bowl that protects and supports the organs of the lower abdominal cavity. The skeleton of the pelvic girdle is much larger, more massive and stronger than the shoulder girdle, since it has to withstand a high load.
Hip joints are under tremendous strain, especially if the person is overweight. Therefore, it is so important to know how to provide maximum protection for the hip joint and maintain its mobility for years to come.
How does the hip work?
With the help of the pelvis, the legs of a person connect with the trunk. Hip joints are paired. Each of them connects two movable bones - the femoral and pelvic bones. Pelvic bone, the anatomy of which is formed by fused flat bones, serves as a support for the spine and internal organs. The hip joint has a globular type, thus providing mobility of the leg in any direction, as well as its flexion and extension.
Detailed anatomy of the pelvis
The most durable and longest in the human body is the femur. At the upper end, it bends inwards, forming a narrow neck bearing a globular head. The head itself is covered with articular cartilage and placed in the cup-shaped acetabulum on the lateral surface of the pelvic bone. The cavity is enlarged by the cartilaginous ring along its edge, the acetabular lip that surrounds the head of the thigh.
Outside, the joint is surrounded by a capsule of fibrous connective tissue lined inside with a synovial membrane. This membrane in the form of a thin mucous membrane provides nutrition and lubrication for the cartilage, releasing the synovial fluid. The capsule itself is strengthened by ligaments between the femoral and pelvic bones. Together, they firmly hold the head of the femur in the acetabulum.
The femoral head is the spherical end of the femur, located in the deep joint cavity of the pelvis. Dislocation in this place happens very rarely, but the problem is in the thin neck of the thigh, which often breaks down in trauma or with thinning and brittleness of bone tissue. This often happens in old age.
Bones of the pelvis
Basis of the pelvis are the sacrum, coccyx and pelvic bones. Together with the joints of the lower limbs, they form a bone ring. Inside its cavity are internal organs. Pelvic bone, the anatomy of which includes three more bones( ischial, pubic and iliac), up to the age of 18 has a cartilaginous connection. Later, ossification occurs, and the three bones indicated above fuse.
The lower part of the pelvis forms the sciatic and pubic pelvic bone. Anatomy shows their connection in the form of a loop.
The iliac bone is broad and pterygoid. It forms the upper part of the hip joint and is easily probed just below the waist of the person. At the junction of all three bones is the acetabulum. This is the normal anatomy of the hip bone.
Loads on the pelvic area
Since antiquity it has been known that the greatest burden falls on the pelvic bone. A detailed anatomy of the pelvis confirms this by the rapid "wear and tear" of the hip joints. The pressure on them often exceeds the weight of the human body itself. And it happens every day: when walking, running and even during a simple standing on your feet. This is the natural anatomy of man.
Pelvic bone, depending on the position of the body, can experience different weight loads. For example, when walking at a speed of 1 km / h, the load on each hip joint is approximately 280% of the body weight, at a speed of 4 km / hour the load increases to 480%, and when jogging is 550%.When a person stumbles, the load on the joint increases to 870% of the body weight.
Women have a wider pelvic bone. Anatomy is slightly different from the male. Therefore, the swing of the oscillations during walking is stronger, hence the hanging of hips is more noticeable. The female pelvis is on average wider, but below the male one. He has a much larger bottom part, so provided by nature, because through him the baby moves during childbirth.
With normal walking, there is a load for each hip joint, which is 2-3 times the body weight. When climbing the stairs, it exceeds the body weight by 4-6 times.
Preservation of pelvic bone health
One of the basic conditions for the health of pelvic bones - the preservation of body weight is normal. With each extra kilogram of body weight, the load on both hip joints increases by 2 kg for walking, 5 kg for lifting and 10 kg for running and jumping. And the extra load is the daily wear of the articular cartilage and the risk of osteoarthritis. Having grown thin, a person protects the joint from premature wear and tear.
In diseases of the hip joint, regular light loads in the form of a walk or an exercise bike are helpful, since they help maintain mobility. If you walk too painfully, a good load will ensure swimming. In this case, the weight of the body does not press the patient's joint. After the fracture, as soon as the doctor resolves, it is also necessary to give a gradual load to the pelvic bones to restore strength and flexibility.
Strength of bones, including the pelvic, as is known, decreases with age, especially in women during menopause. The main preventive measure is the preservation of the strength of bones by eating foods rich in calcium. Most of the calcium is found in fatty dairy products, legumes, fish, green vegetables, nuts and fruits.
