Definitions

  • the present invention relates to an orthopedic foot supporting plate for shoes.
  • the fundamental idea for the construction of an orthopedic articulated loot-support and socket-joint, into which is fitted the joint-head of the footsupport, is founded on scientific knowledge of the construction and action of the foot as the supporting and locomotive organ of the body.
  • the principal organ of the foot is the longitudinal arch of the foot, which is formed of the heelbone, the front portion of which is raised, the adjacent tarsal and metatarsal bones, in co-operation with the respective joints, ligaments and muscles.
  • the stability of the foot-arch and with it of the whole foot is determined by the tripod of the foot formed of three points of support, the after one consisting of the posterior lower corner of the heel-bone and the two frontal points by the heads of the first and fifth metatarsal bones.
  • the weight of the body When standing or walking, the weight of the body is sustained through the talus, below which is the so-called sustentaculum tali, whence it is distributed to the foot tripod and to the foot-arch respectively, so that the weight finally rests on one side upon the heel-bone and on the other on the heads of the first and fifth metatarsal bones. Therefore, in. order that the foot may suitably carry out its duties of standing and walking, there is an absolutely necessary condition of a continual and painless formation and maintenance of a foot-arch capable of maintaining that load and of muscular and articulated action. This condition has been taken into account empirically in the traditional and customary boot and shoe construction already, inasmuch as the heel of the boot or shoe is so connected to the sole as to form the so-called elastic spring of the boot or shoe which supports the foot-arch.
  • the foot-support according to this invention has on the under side a new firm support, the socket joint of the foot-support, in the form of a downward convexity which projects on the under side of the foot support and is usually rounded and which, while the footsupport is in use, acts as an assisting supporting and transmission point between the three points of the natural foot-tripod described above.
  • the socket joint of the foot-support in the form of a downward convexity which projects on the under side of the foot support and is usually rounded and which, while the footsupport is in use, acts as an assisting supporting and transmission point between the three points of the natural foot-tripod described above.
  • a corresponding concavity which serves as a socket in which the articulated convexity of the foot-support is fitted to act as a joint, i. e., to permit of articulated movement.
  • the attached drawing gives a general idea of the construction, showing: (1) a view of the orthopedic plate seen from above, (2) a longitudinal cross-section of a shoe fitted with the orthopedic plate, along the line 1nrn of Fig. 1, and (3) a cross-section along the line h-i of Fig. 1.
  • the orthopedic plate as represented in these designs fits in the usual horizontal position between the heel of the foot and that of the shoe, but possesses .a support aFigs. l, 2 and 3in the form of a downward protuberance, generally rounded. No other orthopedic plate hitherto known possesses this constructive property.
  • the advantage of this new construction of orthopedic plates consists in the fact that the new point of support d is placed conveniently in the right position between the three above mentioned points of support of the foot tripod, so that it makes, in fact, a fourth central point of support of the tripod which increases the capacity of the foot in general, and especially makes it possible really to obtain a correction of foot weaknesses and of fiat feet.
  • the other parts of the orthopedic plate provided with this support a are correspondingly designed in order to complete and strengthen the effect of this support so that the after portion of the heel of the support and the whole section in front of the support a are, by their shape, in effective contact with the arch of the foot in the normal manner.
  • that section of the orthopedic plate in front of the support a is curved downwards so that the front edge k of the plate touches the ball of the sole while the medial (inner) and lateral (outer) angles of this edge k, which are in contact with the first metatarsal at g and the fifth metatarsal at f are flattened out to fit the heads of the metatarsal bones.
  • the whole middle section of the plate between these flattened angles and the support a under the sustentaculum tali of the foot forms a slight convexity, whose vertex is at e and which slopes gently from the inner (medial) to the outer (lateral) edge and also forwards.
  • this new orthopedic plate As a further advantage of this new orthopedic plate, one can state that it is not necessary to take a plaster cast of the foot to be fitted, as the form of theplate does not conform exactly to that of the arch of the foot. It is sufficient, for its construction, to draw the outline of the foot on paper, indicating the position of the support a, the highest point e of the metatarsal elevation and the position of the two flattened sockets at f and 9, after diascopical X-ray examination or photographs. In practice it will even be very convenient to construct these plates in serial production in several types and sizes, which can easily be planned so that one of these will usually be found suitable to fit individual needs.
  • the relation between the foot and the orthopedic plate has to be such that the foot continually feels the pressure and influence of the orthopedic plate, whether standing or walking, at all points of the sole of the foot.
  • the shoe to be fitted with the orthopedic plate as described, according to Fig. 2, so that it has under the support a in the frontal portion of the heel of the shoe and the adjacent portion of the sole connected to it at c, a concave depression a to fit the support a of the othopedic plate.
  • This cavity may also be in the heel of the shoe only, which is suitably prolonged forwards.
  • This cavity a has to be made in order that the support a at its lowest point (1 is suitably embedded and fitted therein.
  • the orthopedic plate may be constructed in any suitable material, such as metal, wood, Celluloid, artificial resin etc.
  • the support a has to fit individually, in shape and form, which however can generally be attained also by serial production in several types and sizes. According to the nature of the material employed or the method of construction, the support a may be hollowed or stamped out in such a way that, seen from above, it has the form of a cavity, the disadvantageous effect of which is prevented by the usual covering 1 of an orthopedic plate or also by being filled with some appropriate material.
