Human Skeletal System

By the time a human reaches adulthood, the skeletal system is made up of 206 bones. It also includes all the tendons, cartilages and the networks of ligaments that help to connect them. This system plays a major role in many body functions like movement, protection, support and stability, blood cell production and calcium storage – that enable us to live.
One of the many groups of bones is called phalanges, the bones found in human fingers. It comes from the Latin word “phalanx” meaning “a compact body of heavily armed men in a battle array”. Ossification of these bones happens from two centers: one for the body and the other one for the proximal extremity. It starts in the body, approximately on the eight week of fetal life. While the formation

It is a case wherein the extensor tendon that crosses the distal interphalageal joint or DIP responsible for the straightening of the finger is damaged, causing the finger to be deformed. A flexion force applied on the tip of the extended finger pushes the DIP to flex. It usually happens on many athletes. This occurs when an object, for example a ball with a high velocity strikes the finger creating a huge impact to the bones and forcibly bends it. A worse thing can happen, when the force is greater it may pull away a bone along with the tendon. As a result, the tip of the finger can no longer straighten itself. Even a minor movement like folding your clothes can cause this kind of injury. This kind of fracture is identified as an avulsion. The long, ring and pinky fingers are the most likely to be…show more content…
Type D
The most common type that causes the shortening of the end bones of the thumb, while the other fingers are left normal. Brachydactyly is diagnosed by doctors through a careful examination of the hands and feet. The use of X-ray is also used so they bone shortened and the type of disorder can be identified. A full skeletal X-ray will be helpful in investigating for other genetic syndromes that may be connected to the present shortening disorder. Since this is a genetic disorder, there is no treatment necessary. Unless it is a part of another syndrome, and it causes other medical concerns, this should be treated. However, persons with this condition could experience problems and difficulties in gripping objects and looking for a glove that will fit. If this has a huge impact on the daily living of the patient, a surgery may help. People with brachydactyly have normal lives. It may have an effect on their self-consciousness and self-esteem about the appearance of their fingers.
Osteoarthritis
According to Hand Facts and Trivia, “Almost 90% of women and 80% of men the age group 75-79 years have hand osteoarthritis.” This means that it is a disease common to anyone. Osteoarthritis is a joint disease which is degenerative meaning it is progressive and can cause loss of function of the hands. With this, the cartilage, a flexible tissue that covers the end of the bones, gradually deteriorates. This can be attributed to an injury of the
