What is the purpose of immobilization of an injury?
This is done to prevent an injured area from moving while it heals. Splints, casts, and braces support and protect broken bones, dislocated joints, and such injured soft tissue as tendons and ligaments. Immobilization restricts motion to allow the injured area to heal.
What is immobilization and how is it secured?
Immobilization can also be secured by a form of traction called skin traction. This is a combination of a splint and traction that is applied to the arms or legs by strips of adhesive tape placed over the skin of the arm or leg. Adhesive strips, moleskin, or foam rubber traction strips are applied on the skin.
What is the difference between a splint and immobilization?
Splints are also often used for finger injuries, such as fractures or baseball finger. Baseball finger is an injury in which the tendon at the. Immobilization refers to the process of immobilizing or fixating the position of a joint, bone, extremity, or torso with a splint, cast, or brace.
What is an example of an immobilization cast?
For example, an injury to the midcalf requires immobilization from the knee to the ankle and foot. Injuries of the hip and upper thigh or shoulder and upper arm require a cast that encircles the body and extends down the injured leg or arm. Casts are generally used for immobilization of a broken bone.

How does immobilization work?from sciencedirect.com
Adsorption immobilization methods involve adsorbing the sensing material onto a solid surface or polymer matrix through the formation of van der Waals and hydrogen bonds. Sensing materials can be adsorbed directly on the fiber optic end. This immobilization method is very simple; however, the adsorbed molecules tend to gradually leach from the solid support, decreasing sensing performance and/or lifetime. In order to overcome leaching problems, the solid support surface may first be modified with complementary functional groups. For example, a hydrophobic surface can be prepared to immobilize a hydrophobic species. Electrostatic interaction can also be employed for immobilization. This immobilization scheme is based on interaction between oppositely charged molecules. For example, an optical fiber surface can be coated with a positively charged layer (i.e., using poly-L-lysine) that interacts electrostatically with negatively charged recognition molecules ( Figure 1.12a ). The electrostatic immobilization method is very easy and highly reproducible but may be affected by changes in the medium pH or by changes in other ion concentrations.
What is the purpose of immobilization in a fracture?from medical-dictionary.thefreedictionary.com
The avoidance of movement of an injured or diseased part, especially a bone fracture, so that healing may take place. Effective fracture immobilization demands that the joint above and below the fracture should be unable to flex. Immobilization is achieved by means of slings, splints, plaster of Paris casts, cold-setting plastic casts and external steel bar fixators of variable design.
How does immobilization improve enzyme stability?from sciencedirect.com
Immobilization can improve enzyme stability under nonaqueous conditions [11]. Enzymes can be immobilized covalently or physically on/in various supports including organic or inorganic polymers. For example, one of the most important immobilized enzyme forms, cross-linked enzyme aggregates (CLEAs), can be prepared by physical aggregation of the enzyme followed by the reaction of surface NH 2 groups on enzyme with a bifunctional chemical cross-linker, such as glutaraldehyde [11a]. Various kinds of CLEAs have been prepared and used in aqueous as well as nonaqueous solvents with the first examples of CLEAs being derived from penicillin G amidase, an industrially important enzyme used in the synthesis of semisynthetic penicillin and cephalosporin antibiotics. Although the free enzyme is known to have a limited thermal stability and a very low tolerance toward organic solvents, CLEAs of the enzyme catalyzed the synthesis of ampicillin in a broad range of organic solvents [11d]. Another example shows that pyruvate decarboxylase stability in a carbon dioxide/aqueous biphasic system was improved by immobilization on ion-exchange polymer ( Figure 3.7) [11e]. Other examples, including a sol–gel-encapsulated alcohol dehydrogenase-catalyzed asymmetric reduction and continuous sustainable processes for enzymatic synthesis of biodiesel in hydrophobic ionic liquids/supercritical carbon dioxide biphasic systems, are shown later. Physical immobilization of cells containing the enzyme on the surface of water-absorbing polymer with hydrogen bonding is shown in Figure 3.4. In that case, the immobilized cell can be only used in nonaqueous solvents. Further details on immobilization of enzymes and their applications are discussed separately in Chapter 4.

What is the immobilization of chiral catalysts?from sciencedirect.com
Immobilization of chiral catalysts on solid supports suffers in general from problems related to inferior catalytic and stereo-inductive ability compared to the homogenous catalysts, but offers advantages of easy separation and recovery with the possibility of recycling. A new method based on polymer-supported BINOL-phosphoric acid catalysts to perform asymmetric organocatalytic transfer hydrogenation has been reported.85 Catalyst 15, with bulky substituents in the 3,3'-positions and styrene groups as linkages for immobilization in the 6,6'-positions, was subjected to cross-linking radical copolymerization with styrene and divinylbenzene and employed as a solid catalyst in the form of a polymer-stick. The performance of this catalyst was tested in the reduction of a benzoxazine in CHCl3 where the reaction proceeded at room temperature to afford the product after 20 h in good yield (96%) and high enantioselectivity (96% ee) ( Figure 27 ). The system provided similar efficiency in other solvents such as benzene, toluene, CH 2 Cl 2, and dibutyl ether. The polymer-stick catalyst, once removed from the reaction mixture and washed, was successfully reused for 12 times preserving its original activity and selectivity. This approach opens opportunities for future practical applications and for the design of one-pot sequential transformations.
What Is a Car Immobilizer?
A car immobilizer system (also known as an engine immobilizer) is a great piece of electronic security technology that acts as a deterrent to vehicle theft. Its goal is to keep a car from being hot-wired and stolen by someone who doesn't have the key to start the engine. According to statistics, since immobilizers were installed in cars, there have been fewer car thefts.
How Does a Car Immobilizer Work?
Today's car keys might be thought of as extra security elements. Transponder chips are found in key fobs and smart keys. When you start the engine or have the key fob inside the automobile, these chips communicate a passcode to the car's immobilizer technology. If the pin code in the key fob meets the one in the immobilizer system, the vehicle will start. Otherwise, your automobile will not start.
