Modern leg prostheses

You've been hearing the term 'liquid implant' a lot lately. It has nothing to do with a full endoprosthesis because it is not a prosthesis. It involves the injection of a type of acid that is intended to rebuild the connective tissue of the cartilage. Any professional will tell you that this is impossible. Under the influence of the degenerative-dystrophic process, a pathology, the joint is completely destroyed and can no longer regenerate. The only solution is surgery.

What types of prostheses are there?

• Cosmetic – they only have a decorative function.
• Functional prostheses – active prostheses that enable gripping. They are controlled by various mechanisms. They can have a cosmetic coating that simulates the appearance of the hand or a modern technical design. Cosmetic – they have a purely decorative function.

Functional prostheses are divided into three further types: tractional, functional and bionic prostheses. They differ in how they work, the materials used, the price and the time it takes the body to get used to them.

• Traction (active, mechanical). These prostheses are moved by springs and cables. They are less functional but less expensive than bionic prostheses.
• Myoelectric (bionic). They are equipped with sensors, electric motors and batteries.
• Robotic. They are specifically designed for specific tasks, e.g. B. for carrying objects or for sporting activities.

What are prostheses made of?

The production of prosthetic limbs is getting better and better. There are changes, especially in the choice of materials. Since the prosthesis needs to be lighter, most parts are made of plastic.

The hip joint socket is usually made of polypropylene. Light metals such as titanium and aluminum have largely replaced the steel in the pylon. Alloys of these materials are most commonly used. The latest development in prosthesis manufacturing is the use of carbon fiber to create a lightweight pylon.

Another new material for prostheses is carbon fiber reinforced plastic. These prostheses are lightweight and are offered in various configurations such as: B. with carbon fiber springs and long composite shafts.

Optimal appearance

MG LATAM Advanced prosthetic feet have a human-like appearance, but above all, their appearance respects individuality by mimicking and accepting the characteristics of each patient, such as: E.g.:

Foot shape, foot size or height, skin texture, skin color and shade, scars, unique features, wrinkles, gender, age and other features that affect the appearance of the foot.

This is due to the anatomical, morphological and hyper-realistic components that make up cutting-edge cosmetics.

Improves the patient's abilities

In addition to being cosmetic and hyper-realistic (if necessary), they feature advanced orthopedic, ergonomic or mechanical accessories that correct and improve various injuries and their consequences.

Solutions recommended by the best surgeons, orthopedists, traumatologists, physiotherapists, orthopedists, psychologists, psychiatrists and relevant medical staff.

Exclusive and innovative for patients who have suffered amputations, deformities and other types of traumatic or congenital injuries.

Prospects for exoprosthetics

The immediate future of exoprosthetics lies in the development of so-called 'bionic prostheses', which are controlled by nerve impulses (similar to a natural limb) and thus offer at least relative functionality. Such models are already being produced both abroad and in Russia. To date, they are all still far from natural perfection, but the very fact that they appear in medical practice would have been pure fiction half a century ago. There is no doubt that methodology and technology will develop rapidly, so that exoprosthetics will become a real, fully functional organ replacement in the foreseeable future.

CONTRAINDICATIONS, PROFESSIONAL ADVICE REQUIRED

Israeli orthopedics has literally helped thousands of patients from all over the world get on their feet. The most frequent visitors to the orthopedic practice include professional athletes and people with an active lifestyle. The problems vary, but among the most common are the need for ligament treatment in Israeli clinics, followed by recovery and return to sports and professional life. An effective method is plastic surgery using transplants: donor material, own tissue and synthetic replacement materials. If the doctor's advice is strictly followed, a return to active life is possible after just three to six months. The innovative InSpace balloon prosthesis is one of Israel's orthopedic achievements. Thanks to this technology, endoprosthetic treatment of the shoulder joint in Israel is more effective and does not require a long rehabilitation period.

Zimmer: Orthopedic technology for the hip

Zimmer is a well-known manufacturer of orthopedic devices and was founded in the USA more than a century ago. Throughout its existence, the company has constantly evolved, introducing the latest technology and developing new designs and prostheses. Its products are delivered worldwide and used in medical centers in Israel, Germany, Russia and the Czech Republic.

This popularity is due to the quality of the products: they are characterized by their longevity and high adaptability.

The company's product range is wide, and it is possible to choose a prosthesis with the right price-quality ratio. Even inexpensive implants allow a complete simulation of the natural joint and have good wear resistance.

What prostheses are there and how long do they last? Zimmer manufactures the following implant designs:

• Knee prosthesis. The clear leader: Almost half of all operations are carried out with an implant. They have a lifespan of 15 years or more;
• Endoprostheses for shoulder joint replacement. A unique and innovative development – a joint with maximum implantability that restores shoulder function to 95 %;
• Hip replacement implants. Wide range of types and individual selection is possible, also in terms of price.

The main difference from Zimmer products is the high adaptability of the prosthesis, which shortens the rehabilitation time.

According to statistics, 99% artificial joints from this manufacturer remain stable for 10-12 years after installation. In almost 85 % cases, the lifespan of a room system is 15-18 years. The company's popularity is no coincidence.

Cost of hip replacement

Complications very rarely occur after hip surgery, and in 10 % cases these are due to incorrect implant selection. Patients experience neck fractures, infections, swelling and hematomas.

The fact is that there is no specific prosthesis, just a universal model that fits everyone without causing side effects.

If you decide to have an endoprosthesis, keep in mind that the price of an implant, whether made of room or ceramic, has nothing to do with the success of the treatment. It is advisable to choose an inexpensive but suitable orthopedic product.

Experienced surgeons have their own preferences for models and brands, so prior consultation and selection is essential. Specialists in both private facilities and public health centers tend to recommend the Zimmer and DePuy brands. Although the prostheses of these manufacturers do not differ fundamentally, their appearance is very similar, they are high quality products with the ability to choose a design that suits your financial capabilities.

How much does treatment with these prostheses cost? The average price in Moscow is 200,000 rubles and includes stay in a private clinic, laboratory tests, hospitalization and further rehabilitation under the supervision of a specialist.

Principles of Rehabilitation

In practice, there are enough examples that patients with the most innovative and expensive implants completely ignore rehabilitation because they consider it unnecessary due to the high price. The result is that patients go back to the doctor after a few years and complain about pain, swelling and limping. In this case, conservative treatment is out of the question - revision surgery is recommended, which involves additional costs and lengthy rehabilitation.

Plastic prosthesis

This is one of the simplest and most commonly used techniques for making removable dentures. The dentures consist of a base that is attached to the gums with suction cups. These suction cups hold the prosthesis in place. A variety of materials can be used for artificial teeth, but most commonly they are made from plastic or porcelain.

It can be made the same day you visit the dentist. It is made based on an impression. Typically used in cases of complete edentulism. If there are still healthy teeth, holes are made in their structure.

Plastic prostheses Dentures are inexpensive, but have many disadvantages. They cause inconvenience when worn. Pronunciation problems may occur and the sense of taste may be significantly impaired. The insecure fixation can cause hair to fall out. To solve this problem, special creams, such as Korega, are used. Its application is quite simple:

1. The mouth should be well moistened by rinsing with water. If native teeth are present, clean them.
2. Apply the cream in short strips to a dry and clean denture.
3. Insert the denture and clench your jaw to ensure it locks into place.

Features of flexible dentures

Flexible dentures consist of a hard and rigid artificial crown and an imitation gum made from a soft base. Thanks to the elasticity of the material, it adapts better to the gum line and, after several years of use, adapts to the gum line even with slight changes in configuration. This variant is considered more durable and has a higher chewing capacity. It looks more natural and is less noticeable on the teeth thanks to the translucency of the material. The brackets and retention pieces are the same color as the gums, so the fit of the prosthesis is aesthetically pleasing and discreet compared to metal abutments. Modern materials are easier to care for, keep dentures clean longer, prevent plaque, do not absorb odors and are more hygienic than hard dentures.

• Hard traditional dentures are often made from acrylic. This material is lightweight, durable, easy to process and inexpensive to produce. Plastic dentures can be fitted in any dental office, and a specialist can easily take impressions and make a model of the prosthesis. However, in order for a plastic denture to be comfortable and fit well, oral preparation is required. Existing diseases, plaque, tooth decay and inflammation may need to be removed. Only then will the prints be very accurate. To improve the quality of the prosthesis, impressions are made using different impression materials.
• After insertion, the patient adapts to the dentures. Due to the low elasticity of the material, plastic dentures can pinch the gums and scratch the enamel of the supporting teeth, causing deterioration. The adjustment time for a plastic prosthesis is on average 1-4 weeks. The product is adjusted and reground to fit the prosthesis. A high quality product can last on teeth for 1-2 years.
• After getting used to it, the plastic prosthesis can be chewed without any problems. However, food can get under the denture if the supporting teeth are missing or the attachment is not tight enough. Due to the strength of the plastic framework, the chewing pressure is evenly distributed over the entire prosthetic surface. This means that the supporting teeth are not overloaded and there is no excessive pressure on the mucous membranes, as is the case with soft nylon dentures. However, the hardness of the plastic can cause gums to rub when speaking or wearing the product. This leads to ulcers, inflammation, stomatitis or gingivitis on the mucous membrane. If the patient chooses this material for the prosthesis, it is important to maintain good hygiene, as acrylic quickly accumulates odors, plaque and bacteria due to its high porosity. The denture should be regularly cleaned by the dentist with a toothbrush, special solutions and ultrasound to care for the product and protect the mouth from diseases.
• Denture adhesive gel should only be used if the denture is not sufficiently fixed after it has been fully adapted to the product. Due to age-related changes, bone loss of 0.3 to 0.5 mm per year often occurs. After a certain period of time, the prosthesis needs to be adjusted or corrected. Acrylic is easy to repair, so with proper care the patient can use the product for 3-5 years. As a rule, the prosthesis is replaced after 2-5 years as the jawbone changes significantly.

Modern flexible prosthesis without plastic

An alternative to acrylic is the acrylic-free prosthesis. The acrylic-free prosthesis was developed by Perflex Ltd (Israel). This material is made from acrylic resin, which does not contain monomers that cause allergies and gum irritation. It is more flexible and has greater strength than acrylic, which often breaks if dropped from your hand during denture cleaning. Acrylic-free has less volume and weight and is therefore easier to adapt; the adaptation time is around 1-2 weeks. The patient feels less in the mouth.

Comparison of acrylic-free and acrylic dentures:

• 1. Hypoallergenicity. Acry-free is a hypoallergenic material and is often recommended for patients with sensitive gums or an allergy to acrylic. Acrylic dentures contain acrylic monomer, which accumulates in the body and causes mucous membrane irritation. In most cases, the negative effects are due to a faulty manufacturing process of the product. The monomer is not added to the material in the correct proportion to its volume, and inexperienced dental technicians add it 'by eye'. This error is completely eliminated when producing Acry-free dentures.
• 2 Longevity. The difference in the lifespan of acrylic and non-acrylic dentures is on average 2-4 years. Acrylic dentures last up to 5 years, while non-acrylic dentures last up to 7 years. It is worth noting that acrylic accumulates more grease and liquids, wears out more quickly, and discolors when it comes into contact with food stains. It needs to be cleaned thoroughly to prevent bacteria from entering the inflammation. Most often a patient changes them after about 2-3 years due to damage, a change in the gum line or the loss of a tooth. Acri Free is softer and does not traumatize the gums, despite its moderately flexible framework. The dense and smooth structure of the material does not promote the accumulation of bacteria and plaque. However, when restoring a large number of teeth, it is necessary to protect healthy teeth from damage and tooth decay. As with plastic dentures, strong and secure anchoring is recommended. Attaching telescopic crowns or brackets improves the properties of the plastic-free dentures and makes chewing easier and more pleasant.
• 3 External appearance. The plastic-free material is designed to withstand negative influences such as food coloring and mechanical pressure. Therefore, scratches are less likely to occur on the surface, and pigment spots are easier to clean with a soft brush and a less abrasive paste. This means the prosthesis maintains its appearance better. In addition, its texture is translucent, has a pink hue and does not stand out against your own gingiva. It merges with its surface. Modern acrylic dentures also have a high aesthetic value, but are not translucent. The pink shade is selected when making the prosthetic model. However, the denture can be seen in bright light and with metal clasps (when attaching the denture to the natural teeth), which significantly reduces the aesthetics of plastic dentures compared to non-plastic dentures.
• 4 effects on the mucous membranes. The rigid structure of acrylic hurts the gums and supporting teeth. Although plastic dentures work well in terms of chewing function, there are still limitations. Hard foods should not be eaten as they can damage the dentures. Due to the lack of adaptation to the denture, chewing can be difficult, especially if the denture is not adequately anchored. Acry-free has a lighter and more flexible structure. Chewing with this type of denture is more comfortable because the framework maintains its shape and distributes the load over the entire gum surface. There is no discomfort when wearing the prosthesis as the surface is smooth and soft.
• 5 Special care properties of the prosthesis. The porosity of plastic leads to plaque formation, odor and discoloration. The patient should pay attention not only to whether the products are healthy, but also to whether they discolor the prosthesis or cause it to break. This entails certain limitations and inconveniences. Acry-free is less demanding in terms of maintenance as it has a smooth surface. To remove plaque, you just need to regularly remove food particles in the morning and evening, use a soft toothbrush and toothpaste without abrasive particles, and clean once a month with a special solution. If you wear dentures, it is important to rinse your mouth after every meal, clean the gums, and rinse the dentures to prevent food from getting under the dentures, which can cause pain and discomfort. Having your dentures cleaned by a specialist and regular check-ups with your dentist are essential if you are missing teeth and wear dentures.
• 6 Price of dentures and adjustment. The price of dentures varies greatly. Typically, the price difference for a plastic denture is about half the price of a non-acrylic product. A dentist or prosthodontist must have a high level of specialist knowledge. Therefore, the cost of an acrylic-free denture is higher for the dentist. More accurate diagnosis and more expensive impression materials are needed. Ultimately, however, the patient receives more comfortable and long-lasting care.

How much do bionic prostheses cost (and why are they so expensive)

According to Grand View Research, the global robotic prosthetics market was $790.8 million in 2016. The forecast for 2025 is up to 500.75 billion. The market is growing with advances in technology as well as the number of amputations and their funding by non-governmental organizations.

According to the US analysis company Frost & Sullivan, the average price of modern, improved prostheses is between $5,000 and $50,000.

The Bebionic prosthesis costs more than 10,000 $, the i-limb costs between 60,000 and 120,000 $ and the Argus II bionic eye costs around 150,000 $.

In Russia, a bionic arm costs between 100,000 and 1.5 million rubles.

So far, prostheses are not widely used and their development is quite expensive and requires the collaboration of engineers, biologists and doctors. In addition, the prostheses are made individually each time: the sleeve to which the bionic arm or leg is attached must be perfectly tailored in shape and size. Sometimes multiple models need to be made and the training and rehabilitation takes weeks.

In most cases, prostheses are paid for by an insurance company or the state - like in Russia. However, you have to go through many offices and medical examinations, and the choice of models is very limited.

3D printing can help here: with its help you can create inexpensive prostheses that take into account all individual characteristics and are designed according to your own taste. They are also very light. Such prostheses cost up to $10,000.

The latest craze: hands made of Lego, legs for athletes and supermodels

In recent years, bionic prostheses have fulfilled more than their primary function: they have become more than a way of life, a hobby or even a fashion accessory.

The Hero Arm is a development by Open Bionics and Disney. It was invented for children, but adults also use it. Each model is based on popular comics, films or games: Iron Man, Star Wars, Cold Heart, Deus Ex.

Hugh Herr, a professor at the Massachusetts Institute of Technology, leads an active lifestyle as a mountain climber with two prosthetic legs. He also conducts research in the field of biomechatronics, a technology that combines human physiology with electromechanics. In 2011, Time magazine called him a 'leader of the bionic age'.
