Definitions

  • the present invention relates to an orthopedic shoe, in particular for patients with joint laxity and for wearers of hip prostheses.
  • osteoarthritis of the hip, knee and ankle undergoes progressive aggravation if the foot is pressed on the ground in a normal manner, that is to say without the shock being absorbed.
  • Shoes which are provided with elastic elements with linear elasticity, such as, for example, steel springs, installed inside the heel in order to make it elastic.
  • the drawbacks which derive from these known shoes fitted with a spring inserted in the heel consist essentially in the fact that during the unloading phase, that is to say when the foot is lifted from the ground, the springs fully restore the energy elastic accumulated during the loading phase, that is to say when the foot is pressed on the ground, and consequently, the reaction exerted by the ground on the supporting foot is not damped, but is retransmitted unchanged on the lower support limb.
  • the main object of the present invention is to eliminate the aforementioned drawbacks and to obtain a damped load distribution on the calcaneus of the foot and simultaneously on the sole of the foot when the foot is supported on the ground.
  • GB 743 149 describes a shoe with a cavity corresponding to the heel, in which is housed a resistant element of foam rubber or similar material which is raised relative to the heel in the rest position, with a flexible sole fixed on the aforementioned element, the rear part of which is movable in vertical direction under the action of the wearer's foot, with a pad also made of foam rubber or the like, which extends over the entire surface of the shoe in the heel area and beyond.
  • this known shoe does not increase the muscular activity of the lower limbs with which it is necessary to obtain motor rehabilitation of patients suffering from articular laxities and with sagging of the arch of the foot.
  • FIG. 1 shows a view in median longitudinal section of a shoe according to the invention, with the whole foot resting on the ground;
  • FIG. 2 shows the sectional view along line AA of FIG. 1;
  • FIG. 3 shows the sectional view along line BB of FIG. 1;
  • FIG. 4 shows a view in median longitudinal section of the shoe of FIG. 1 with the foot resting on the ground in correspondence with the point of the heel;
  • FIG. 5 shows a variant of the view in section along line AA in FIG. 1.
  • the body (5) of the sector (8) which is intended to be below the calcaneus (9) and to support the maximum weight of the patient at the time of the pressure on the heel - during wandering - has an outside diameter smaller than the diameter interior of the cavity (4) of a few mm, so that, in the presence of the load, it can deform freely in height and in width without being hindered by the area of the sector which surrounds it.
  • the body (5) of the sector (8) which is intended to be below the calcaneus (9) and to support the maximum weight of the patient at the time of the pressure on the heel - during wandering - has an outside diameter smaller than the diameter interior of the cavity (4) of a few mm, so that, in the presence of the load, it can deform freely in height and in width without being hindered by the area of the sector which surrounds it.
  • said body (5) of the sector (8) is of frustoconical shape with vertical axis with the large base placed at the top or at the base, and preferably with a blind axial hole (50), that is to say - say opening only downwards.
  • the surface (80) of the sector (8) which delimits the cavity (4) is advantageously provided with two annular projections (81) which, when the body (5) and the zone of the sector ( 8) which surrounds it are under the load of the foot, increase the resistance to the horizontal deformation of said sector (8) so that this deformation is progressive and slower.
  • the two lateral longitudinal reliefs (6.60) are of equal or different length, but of different height to take account of the natural conformation, that is to say of the curvature , of the sole of the foot (10), which has a larger arrow corresponding to the inner side of the foot.
  • the reliefs (6.60) of the intermediate element (1) provide rigid support for the sole (10) of the foot, which allows effective blood stimulation in the vessels of the sole of the foot and its possible reshaping.
