Problems solved by technology

[0016] Given those limitations, the device disclosed in patent EP 1125567 does not allow to differentiate between those patients who require a surgical technique with greater or lesser rotational control, and also does not allow for patients with associated ligamentous injuries (most common) Evaluate

Embodiment Construction

[0060] as in figure 1 , 2 , 3 and 4, the device 1 described in the present invention basically consists of four parts, namely the part 2 for the rear support and fixation of the thigh, the part 2 for the rear support and fixation of the leg 3. Support 4 and part 5 for rear support and fixation of the foot.

[0061] These four parts each comprise a number of straps (not shown in the figures) which together with parts 8 and 9 will ensure the placement of the leg, thigh and foot and remain fixed against the device 1 (object of the invention) .

[0062] All materials used in the invention are plastics, resins and composites in order to ensure that the images obtained by means of the device 1 by means of computed tomography or magnetic resonance imaging do not show distortions.

[0063] The device 1 comprises a separate tool 20 for pushing the front region of the leg backwards and a tool 21 for pushing the rear region of the leg forward (in figure 2 shown in ), the tools 20 an...

Abstract

The present invention relates to a device (1) for measuring the knee laxity, with or without use of additional means of diagnosis such as computed axial tomography and magnetic resonance imaging, evaluating the instability of the knee due to rupture of any ligament, namely the anterior cruciate ligament, posterior cruciate ligament, postero-internal capsule, postero-external capsule, as well as around the axis of an orthonormal referential, that comprises three parts respectively to accept and retain the thigh, leg and foot. The device (1) includes independent means (20) and (21) to push backward the anterior zone of the leg and to push forward the posterior zone of the leg, and independent means (12) and (13) to push the part (5) for support and fixation of the foot in clockwise direction and in anti-clockwise direction.

Description

technical field [0001] The present invention relates to a method for assessing instability of the knee due to rupture of any ligament and along all axes of the orthogonal, anterior, posterior, anterior internal, anterior external, posterior internal and posterior external references Sexual means, said any ligament namely anterior cruciate ligament, posterior cruciate ligament, posterior internal capsule, posterior external capsule. Background technique [0002] The number of lower extremity joint injuries has increased significantly in recent decades. This problem affects athletes and any other individual who may be the victim of an accident and / or congenital disease. [0003] This type of injury and trauma cripples the individual because it creates instability of the knee, preventing the normal function of the knee (rotation, propulsion and extension), thus making the individual unable to perform their daily tasks. [0004] In practice, treatment for a knee ligament ruptu...
