INTRODUCTION : equilibrium, state of balance. When a body or a system is in equilibrium, there is no net tendency to change. In mechanics, equilibrium has to do with the forces acting on a body. When no force is acting to make a body move in a line, the body is in translational equilibrium; when…
What is an Osteoma? An osteoma (plural: osteomata) is a new piece of bone usually growing on another piece of bone, typically the skull. It is a benign tumor. When the bone tumor grows on other bone it is known as homoplastic osteoma when it grows on other tissue it is called “heteroplastic osteoma What…
Bone cysts are fluid-filled spots that form in bone. Most go away on their own over time. Bone cysts are generally diagnosed through X-rays, often when a child is being seen for another condition. While there are often no symptoms, bone cysts can cause the bone to be weak enough to fracture when it otherwise…
What is a Gravity? DEFINATION: Gravity is a force that tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth’s gravity is what keeps you on the ground and what causes objects to fall. Centre…
Achondroplasia is a form of short-limbed dwarfism. The word achondroplasia literally means “without cartilage formation.” Cartilage is a tough but flexible tissue that makes up much of the skeleton during early development. Causes: Achondroplasia is caused by a gene alteration (mutation) in the FGFR3 gene. The FGFR3 gene makes a protein called fibroblast growth factor…
Plantar fasciitis is a common cause of pain under the heel. Heel pain is not usually caused by a single injury, such as a twist or fall, but from repetitive stress and pounding of the heel. Common causes include: … Heel bursitis: Inflammation can occur at the back of the heel, in the bursa, a…
DEFINATION : Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding and rolling friction occur between…
Definition- Osteopetrosis is a bone disease that makes bones abnormally dense and prone to breakage (fracture). Researchers have described several major types of osteopetrosis, which are usually distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked. Osteopetrosis (“marble bone disease”) is a descriptive term that refers to a group of rare, heritable…
DEFINATION : Haglund’s syndrome is a constellation of soft tissue and bony abnormalities and represents one cause of retro-calcaneal pain consisting of inflammation of the regional soft tissues, e.g., retro-calcaneal bursitis, superficial tendo Achilles bursitis, and thickening and/or inflammation of the Achilles tendon, associate Haglund’s syndrome is a cause of retrocalcaneal pain. The clinical diagnosis of…
The wrist joint (also known as the radiocarpal joint) is a synovial joint in the upper limb, marking the area of transition between the forearm and the hand. In this article, we shall look at the structures of the wrist joint, the movements of the joint, and the relevant clinical Structures of the Wrist Joint…
