This serves to raise the foot high enough to prevent the toe from dragging and prevents the slapping. [7] [8] To accommodate the toe drop, the patient may use a characteristic tiptoe walk on the opposite leg, raising the thigh excessively, as if walking upstairs, while letting the toe drop. Other gaits such as a wide outward leg swing (to avoid ...
As a general rule, this vowel almost always acts as a joint-stem to connect two consonantal roots (e.g. arthr-+ -o-+ -logy = arthrology), but generally, the -o-is dropped when connecting to a vowel-stem (e.g. arthr-+ -itis = arthritis, instead of arthr-o-itis). Second, medical roots generally go together according to language, i.e., Greek ...
Angular motions (or rotary motions) occur when an object is around another object increasing or decreasing the angle. The different parts of the object do not move the same distance. Examples include a movement of the knee, where the lower leg changes angle compared to the femur, or movements of the ankle. [2]
The cracking of joints, especially knuckles, was long believed to lead to arthritis and other joint problems. However, this is not supported by medical research. [2] [3] The cracking mechanism and the resulting sound is caused by dissolved gas (nitrogen gas) cavitation bubbles suddenly collapsing inside the joints. This happens when the joint ...
Each movement at a synovial joint results from the contraction or relaxation of the muscles that are attached to the bones on either side of the articulation. The type of movement that can be produced at a synovial joint is determined by its structural type. Movement types are generally paired, with one being the opposite of the other.
They are analogous to the knuckles of the hand, and are consequently known as toe knuckles in common speech. They are condyloid joints , meaning that an elliptical or rounded surface (of the metatarsal bones) comes close to a shallow cavity (of the proximal phalanges).

Almost every joint in the body can be 'cracked' in this way, but the joints which require the least amount of force to produce this effect include the hallux (big toes), the knuckles and the neck joints. This phenomenon is caused when the movement of the joint lowers the pressure of its synovial fluid, causing the bubbles to form and burst.
