Introduction: The hip joint is a ball-and-socket joint that connects the thigh bone (femur) to the pelvis, enabling a wide range of movement. It plays a crucial role in supporting the body’s weight and facilitating activities like walking, running, and jumping. Structures of the Hip Joint : Articulating Surfaces : Ligaments: Intracapsular: Extracapsular: Stabilising Factors:…
Definition Baxter’s neuropathy is a nerve entrapment syndrome that results from the compression of the inferior calcaneal nerve. Selective fatty atrophy of the abductor digiti minimi muscle is the unique sign of this neuropathy. Baxter’s Entrapment is an entrapment (or compression) of the Inferior Calcaneal Nerve just under the base of the arch of the…
INTRODUCTION: A lever is a rigid bar that moves on a fixed point called the fulcrum when a force is applied to it. Movement is made possible in the human body by lever systems which are formed by our muscles and joints working together. An understanding of the lever systems in the body helps us…
DEFINATION: Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of vertigo, which is a symptom of the condition. Though not fully understood, BPPV is thought to arise due to the displacement of otoconia (small crystals of calcium carbonate) from the maculae of the inner ear into the fluid-filled semicircular canals. These semicircular canals…
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…

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…
