PROSTHETIC IMPLANT OF THE ESR TYPE AND METHOD FOR ADJUSTING THE PROSTHETIC IMPLANT

A prosthetic implant (100) of the ESR (energy-storing-and-returning) type, comprises an upper assembly (200) and a lower assembly (300), configured to define a foot and including a lower blade (400b), an intermediate blade (400b) and an upper blade (400c). The upper blade (400c), the lower blade (400a) and the intermediate blade (300c) are fastened stably to each other at at least one connecting point (C) located in the front region (300a) or in the middle region (300b) of the foot. An articulated joint (5009) is interposed between the lower assembly (300) and the upper one (200) to allow relative motion between them. The implant comprises a connector (600) having a first end (600a) that is connected to the upper assembly (200) and a second end (600b) that is connected to the intermediate blade (400b) of the lower assembly (300). At least one between the first and the second end (600a, 600b) of the connector (600) is movable along a movement direction (X) to vary the force applied on the intermediate blade (400b) of the lower assembly (300).
