Although prosthetic joints and limbs offer mobility to patients who may otherwise be immobile, they do come with some disadvantages. In the case of prosthetic limbs, there is a high initial cost, the limbs are difficult for some patients to learn to use, and regular repair and maintenance are needed. Prosthetic joints, such as prosthetic knees, require extensive and invasive surgery to implant and often offer limited motion.Continue Reading
There are two main types of prosthetic limbs: battery powered and electric limbs. The disadvantage of a battery powered limb, when compared to an electric limb, is a more mechanical appearance. Many people also find battery powered limbs harder to learn how to use since they require the input of more physical strength. Electric limbs are more costly than battery powered limbs, and they are also heavier. The repair cost is higher than for battery powered limbs.
When suffering from severe arthritis in a knee, hip or other large joint, replacing the joint with a prosthetic joint is often a treatment option. Other treatment options include surgical repair of the existing joint and the use of pain medications. Disadvantages of a prosthetic joint, when compared to other options, include an increased risk of surgical complications, rejection by the body of materials used to make the prosthesis, and a limited range of motion when compared to a natural joint.Learn more about Conditions & Diseases
Fixed-bearing and mobile-bearing implants are the two major types of knee prosthetics that facilitate total replacement, but each FDA-approved manufacturer offers specific levels of flexion, according to Healthline. Two important subcategories are cruciate-retaining and posterior-stabilized implants, and choosing between them depends on whether the patient’s cruciate posterior ligament is preserved or removed. For partial knee implants, some prosthetics are unicompartmental devices designed to fit one knee section, while modular designs allow surgeons to choose which components to implant.Full Answer >
Depending on the severity and location of an ulcer on the body, treatments range from antibiotics to prosthetics. For example, Healthline explains that peptic ulcers located in the stomach, esophagus and duodenum may be treated with antibiotics or proton pump inhibitors. According to Cleveland Clinic, leg and foot ulcers may require the use of anti-clotting medications or orthotics. Mouth ulcers can be treated with antiseptic gel, notes Better Health Channel.Full Answer >
Prolotherapy, repeated injections of a sugar solution into joints affected by arthritis, is a controversial therapy that may not work, with disadvantages that include irritating cells and tissues, and changing the composition of the synovial fluid to cause more irritation instead of less according to the Arthritis Foundation. On the other hand, some research studies show that prolotherapy provides relief for arthritis symptoms beyond a placebo effect.Full Answer >
Spongy bone, also called cancellous or trabecular bone, provides structural support and facilitates movement of the joints and limbs. Spongy bone is light and porous and found in most parts of the body and in other bones that do not typically endure large volumes of mechanical stress.Full Answer >
