Pulleys play a significant role in biomechanics, particularly in the context of human movement and the musculoskeletal system. They are mechanical devices consisting of a grooved wheel and a rope, cable, or belt that runs along the groove. Pulleys are designed to change the direction of a force and provide mechanical advantage, making it easier…
Definition: Peroneal tendonitis occurs when the peroneal tendons become inflamed. This happens when there is an increased load and overuse of the tendons, leading to them rubbing on the bone. Peroneal tendinitis is a condition that can be acute or become chronic (peroneal tendinopathy) whereby there is an irritation to one or both peroneal tendons…
Definition of Ankle Sprain : –An ankle sprain is an injury to the tough bands of tissue (ligaments) that surround and connect the bones of the leg to the foot. The injury typically happens when you accidentally twist or turn your ankle in an awkward way. This can stretch or tear the ligaments that hold…
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…
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…
