INTEGRAL LEG PROTECTION SYSTEM

DELATECNICA SECTOR

The present invention relates to a system of integral protection of the leg that protects the ankle, tibia, knee and femur; both of torsion joint injuries; as of the tibia and / or of the femur by impact and, more specifically, it belongs to the orthotic sector.

The main object of the present invention is a system of integral protection of the leg, capable of protecting the ankle and the knee in both valgus or varus forces and the tibia and the femur from possible impact injuries. Providing safety and stability throughout the leg and, without generating muscular atrophy, either to the femoral biceps or the femoral quadriceps.

BACKGROUND OF THE INVENTION

At present there is a great demand for orthotics for the protection of ankle, tibia, knee and femur, due in large part to the increase in sports activities by the population, as well as by people with polytrauma, mainly caused by traffic accidents.

Currently there are different products that protect ankles, knees, tibiae and femur, individually, but not jointly and comprehensively and in a single device. In sports such as skiing, most injuries occur in the knee and ankle joints due to sprains and impact on the tibia and femur. Existing products to protect them do so individually. In accident victims with polytraumatisms we find the same situation, finding no orthotics that protect the ankle, tibia, knee and femur together in a single device and, in addition to being easy and fast colocation.

We can specify the typical injuries in sports such as skiing in the following areas and characteristics:

Ankle:

Ankle injuries can be due to torsion, valgus or varus that lead to maleolar fractures and axial compression injuries that cause tibial pilon fractures.

Ligament injuries in the ankle are frequent and especially in activities that require jumping and turning such as sports such as skiing.

Most injuries occur when there are internal inversion and / or rotation forces applied to the foot with the ankle in plantar flexion. As these forces occur during support, the stabilizing effects of the articular surface are minor.

There are different types of anklets on the market to protect the articulation, but always individually and in many cases using hard or metal parts; There is a risk of injury or injury from these parts.

Tibia:

Direct fractures will be produced! at the point of impact (direct blows to the tibia).

Indirect fractures will be produced! at a distance from the point of force application (leg torsion, body rotation).

There are different shin guards on the market to avoid fractures or injuries due to impact on the tibia, but individually.

Knee:

Tendon muscle injuries of the knee are very frequent in sports such as skiing and endanger the sports life of the athlete in multiple disciplines.

The direct lesions are sedated by the application of a force to the knee that forces a varus or valgus, causing the initial injury of the lateral or mediated structures and can reach the central pivot.

Indirect injuries are due to a static imbalance conjugated with a muscular one.

There are two dangerous positions that generate frequent injuries in sports practices such as skiing:

The external valgus-rotation in flexion: typical of a bad fixation of the foot or with little balance that causes the rupture of the mediated elements, of the anterior cruciate ligament and, possibly, of the external meniscus. Typical injury in the ski descent.

Internal vario-rotation in flexion or extension: typical of the support leg or in a sharp turn, which causes the injury of the anterior cruciate ligament and, possibly, a bone capsular tear of the tibial external antero flange. Injury in descent or with jump.

In knee injuries of the anterior and / or posterior cruciate ligament is caused by an abnormal displacement of the tibia over the femur.

Patellar tendon tears are typical of athletes who have suffered old injuries and repetitive episodes of tendonitis. In knee flexion position and abrupt contraction of the quadriceps is the usual form of injury of the patellar tendon and is the usual position of sports such as skiing due largely to a continuous position of knee flexion.

Both the lateral ligaments and the cruciate ligaments of the knee stabilize the knee from the inside as they connect the spines of the tibial plateau with the inside of the condyles. The cruciate ligaments are the most important in the rotational movements of the knee when it is flexed and its rupture causes joint alterations.

Currently there are different types of knee pads to protect the joint:

On the one hand there are simple or tensileelastic knee pads, usually made of neoprene, which increase the temperature and can improve proprioception and provide a sensation of knee support. The problem with this type of knee pads is that they do not protect the knee from axial rotation and not

5

they serve for an effective support neither of the ligaments nor of the menisci and especially in sports such as skiing that transfers a lot of energy to the knee.

On the other hand are the femoropatellar and prophylactic knee pads that are designed to resist axial rotation, maintain the alignment of the knee and generate stability. The problem with this type of knee pads is that they press excessively through ribbons, straps or reinforcements, causing muscular atrophy in the femoral biceps and in the femoral quadriceps. Another drawback of this type of knee pads is its rigidity and its hard parts can cause injuries or wounds in case of coffee.

There are other types of knee pads such as rehabilitators or functional ones, but due to their rigidity and lack of mobility, they are not suitable for sports.

Femur:

Falls are the main causes of femur fractures.

In young people it is associated with high-energy trauma, such as sports such as skiing or traffic accidents.

In sports such as skiing, a fracture of the femoral head could also occur due to the axial force applied to the knee in flexion.

There are different protectors on the market to avoid fractures or injuries due to the impact of the femur, but individually.

For the protection of the leg the musculature is basic:

The biceps femoris is a flexor muscle of the leg and also an agonist muscle for external rotation of the leg; his atrophy generates risks of injury. The quadriceps femoris is responsible for the extension of the leg and three of the four muscles that compose it converge in the patellar tendon, so that its atrophy will generate risks of injury. The cuddriceps is the most powerful muscle in the body and protects the femur.

Popliteum is the most important stabilizing element in the area of the tibial plateau, as it pulls from the posterior body of the external meniscus during the flexion movement and, in internal rotation, with the fixed femur, produces an internal rotation movement of the tibia.

The flexion of the knee is produced by the contraction of the muscles that overcome the femorotibial joint by the posterior aspect. Muscles such as the internal rectum, the sartorium, the biceps femoris, the popliteum or the plantar; they mostly originate in the coxal area or in the femur and are inserted in the back of the tibia or perone.

The improvement of extensor muscle activation and proprioception is responsible for the effect on motor control and knee stability.

Muscular atrophy contributes to increased instability in joints with failures, repetitive strains and ligament and meniscal lesions.

Rotational movements in flexion are characteristic of sports activities such as skiing. The knee pads that transfer fixation to the joint and stability, generate muscular atrophy due to the pressure they exert on the muscles, have hard or metallic parts so that they can generate injuries or wounds; while the knee pads without these parts, do not have the desired effectiveness to protect and stabilize the knee in a sport as demanding for the knee as is skiing.

As much for accidents with polytraumatisms as in sports activities, there is a great demand for orthoses for the protection of the ankle, the tibia, the knee and the femur; But there is no product that protects all areas at once, together and comprehensively in a single device and, which guarantees stability and safety without generating muscular atrophy.

For the practice of skiing or similar sports, a large amount of specialized material is required, both for impact and thermal protection. Adding protections for the ankle, the tibia, the knee and the femur individually would generate a lot of time in the placement of all the equipment becoming tedious and even uncomfortable.

EXPLANATION OF THE INVENTION

The integral protection system of the leg object of the invention is a new system that guarantees protection both by torsion and impact, in any activity that involves risks for the ankles, tibia, knee and femur; providing them with security and stability using a single device.

With the integral protection system of the leg object of the invention, the problems of sprains in the ankle are solved, providing stability and protection; protects the tibia and the femur from impacts and solves the problems of axial rotation of the knee; without generating muscular atrophy either in the femoral biceps or in the femoral quadriceps, or in muscles of the femorotibial part of the posterior face; protecting the joints and providing them with stability.

With the integral protection system of the leg object of the invention, it is intended to protect the ankle, tibia, knee and the femur, in a joint and integral way using a single device and, not individually as is currently the case.

An important feature of the integral protection system of the leg object of the invention, in addition to its lightness, is that it has no metal fixings, or hard parts, so it can be used in sports without risk of injury or injury.

Another important characteristic of the system of integral protection of the leg object of the invention is that it does not generate muscular atrophy since it does not press the muscles that give protection and stability to the joints and the leg with tapes or hard parts.

An important feature of the protection system of the leg object of the invention is its easy and rapid placement, reducing the time required for placement; which is important, since in this way it is much more comfortable to use by children in the practice of sports or in people with polytrauma.

The integral protection system of the leg object of the present invention comprises a long fixing tape, a lateral fixing tape and another ankle fixing tape. Between the three tapes it is possible to keep stable and provide support and security to the joints, in addition it will have a protection in the tibia and another in the femur, protecting them from possible impacts.
