MODE FOR CARRYING OUT THE INVENTION

[0021] FIG. 1 through FIG. 3 illustrate an inner-side pillar supporter according to Embodiment of the present invention. The inner-side pillar supporter comprises a pillar 1 shown in FIG. 1, a strip-shaped bandage 10 shown in FIG. 2, and a planar fastener 17 shown in FIG. 3.

[0022] The pillar 1 includes a bent plate 2 made of plastic, an upside cushioning material 4(a) and downside cushioning material 4(b) made of sponge, and a male planar fastener 3 formed as a hook shape. As can be understood from the plan view shown in FIG. 1, the bent plate 2 makes a configuration that has a rectangular shape with a broad width at the upside, and whose width narrows down toward the lower end at the downside. As can be understood from the side view therein, the bent plate 2 makes an inverted letter-“S” configuration that has an upper-end section warping in a direction obliquely to the left on the diagram, and a lower-end section waring slightly in another direction obliquely to the right thereon. In addition, as can be understood from the cross-sectional views therein, the bent plate 2 makes a bent plate whose cross section curves as an arc shape. Sizes of the bent plate 2 are 15.2 cm in the longitudinal direction, 5.2 cm at the upside in the width direction, and 2 mm in the thickness direction.

[0023] On a section involving an upside on the inner side of the bent plate 2, the upside cushioning material 4(a) is fixed; whereas the downside cushioning material 4(b) is fixed on the lower section while the latter is separated off from the former by a minor clearance provided therebetween. The planar fastener 3 is fixed to the bent plate 2 at the lower side on the outer side. The upside cushioning material 4(a) has 8.3 cm in the longitudinal direction, 5.2 cm in the width direction, and a thickness of 5 mm. The downside cushioning material 4(b) has 6 cm in the longitudinal direction, 5.2 cm in the width direction, and a thickness of 5 mm. The planar fastener 3 has 7 cm in the longitudinal direction, a maximum length of 4.7 cm in the width direction, and a minimum length of 2 cm in the width direction.

[0024] The upside cushioning material 4(a) comes into contact with an upper section in an ankle at an ankle joint, and is then fixed to the upper section; whereas the downside cushioning material 4(b) comes into contact with the ankle's lower section, and is then fixed to the lower section. Thus, the ankle comes to be located between the upside cushioning material 4(a) and the downside cushioning material 4(b).

[0025] The bent plate 2 is constructed as described above. That is, the downside cushioning material 4(b), the section in the bent plate 2 retaining the downside cushioning material 4(b), and the section involving the planar fastener 3 constitute the fixed portion according to the present invention; whereas the upside cushioning material 4(a), and the section in the bent plate 2 retaining the upside cushioning material 4(a) constitute the inversion preventing portion according to the present invention.

[0026] The strip-shaped bandage 10 includes a strip-shaped body portion 11 shown in FIG. 2, and a planar fastener 17 shown in FIG. 3.

[0027] The strip-shaped body portion 11 has 80.5 cm in the longitudinal direction, 5.1 cm in the width direction, and a thickness of 1 mm. The strip-shaped body portion 11 is provided with a female planar fastener having a large number of fine rings on the surface over the entire face. Note that the female planar fastener has 80.5 cm in the longitudinal direction, 4.4 cm in the width direction, and a thickness of 1 mm.

[0028] The strip-shaped body portion 11 is formed of such three strip portions as a leading-end strip portion 12, a central strip portion 13, and a trailing-end strip portion 14. The leading-end strip portion 12 has 56.2 cm in the longitudinal direction, 5.1 cm in the width direction, and a thickness of 1 mm. The leading-end strip portion 12 is provided with a planar fastener 16 at the free end. Note that the planer fastener 16 has 7.3 cm in the longitudinal direction, 4.4 cm in the width direction, and a thickness of 1 mm.

[0029] The central strip portion 13 has 9.3 cm in the longitudinal direction, 5.1 cm in the width direction, and a thickness of 1 mm. The central strip portion 13 is provided with a slit 15 into which an ankle is fitted at the time of mounting or applying. The slit 15 is a 9.3-cm cut or opening that is parallel to the longitudinal direction of the central strip portion 13, and is arranged at the middle in the width direction of the central strip portion 13.

[0030] The trailing-end strip portion 14 has 15 cm in the longitudinal direction, 5.1 cm in the width direction, and a thickness of 1 mm.

[0031] The planar fastener 17 has a male planar fastener on the surface, and is formed roughly as a trapezoidal configuration whose lower base is 4.8 cm, upper base is 3 cm and height is 4 cm.

[0032] The inner-side pillar supporter according to Embodiment comprises the above-mentioned constituents.

[0033] Next, an example of mounting or applying the inner-side pillar supporter will be hereinafter described using FIG. 4. Before mounting or applying the inner-side pillar supporter to an ankle joint, the planar fastener 16, which is fixed to the leading end of the strip-shaped bandage 10, is pressed and then applied to the planar fastener 3, which is fixed to the outer side in the bent plate 2 of the pillar 1 at the lower side, to put the strip-shaped bandage 10 in a state where it extends straight from the lower side of the pillar 1 as shown at (I) in FIG. 4. Thereafter, as shown at (I) in FIG. 4, the strip-shaped body portion 11 is elongated downward as follows: the upside cushioning material 4(a) is brought into contact with an upper side in the ankle so as to make the ankle in the ankle joint meet or face the space that the pillar 1 includes between the upside cushioning material 4(a) and the downside cushioning material 4(b); and then the downside cushioning material 4(b) is brought into contact with an inner side of the ankle joint so as to locate it below the ankle. Next, as shown at (II), the leading-end strip portion 12 is circled around to the outer side of the foot by winding it around the sole that intervenes from the plantar arch to the heel. Next, as shown at (III), the leading-end strip portion 12 is passed around from the ankle (i.e., the outer side of the foot to the front of the leg's slender part above the foot). Next, as shown at (IV), the leading-end strip portion 12 is circled around from the front of the ankle to the rear of the ankle while fixing the fixed portion of the pillar 1. Next, as shown at (V), the leading-end strip portion 12 is circled around from the rear of the ankle to the front of the ankle through the outer side of the foot. Next, as shown at (VI), the leading-end strip portion 12 is circled around from the front of the ankle while fixing the fixed portion at the lower side. Thereafter, the leading-end strip portion 12 is passed around the foot to the outer side after hooking the heel onto the slit 15 formed in the central strip portion 13 and then fitting the heel into the slit 15. Moreover, the trailing-end strip portion 14 is circled around the fixed portion from the front of the ankle. Finally, the planar fastener 17 is used on the front side of the strip-shaped body portion 11 to fasten the inner-side pillar supporter according to Embodiment whose body portion 11 has been put in a circled-around state.

[0034] The inversion prohibiting portion, which exists from the upper side to the middle section in the pillar 1 to restrict the ankle from inverting, is not fixed at all. Therefore, the inversion prohibiting portion does not restrict plantar/dorsal flexing movements at the ankle joint, because it can swing freely in the front/rear direction of the foot depending on the plantar/dorsal flexing movements. Moreover, it is easy for a patient to perform the plantar/dorsal flexing movements, because the downside cushioning material 4(b) and the ankle joint slide one another.

[0035] As a result, the inner-side pillar supporter according to Embodiment not only restricts the ankle joint from inverting but also is fully free of restricting the plantar/dorsal flexing movements at the ankle joint.

[0036] (Employment Evaluation)

[0037] The inner-side pillar supporter according to present Embodiment was used to treat 24 cases of fresh ankle-joint inversion sprain for patients who visited an orthopedic clinic operated by the applicant of the present application. For 10 cases of minor injury, the inner-side pillar supporter was mounted or applied to the patients from the beginning. For the other 14 cases, the inner-side pillar supporter was mounted or applied to the patients after they had undergone a cast fixation for from five days to three weeks approximately. In all of the cases, the inner-side pillar supporter was always mounted or applied to the patients other than such occasions as the patients took off the inner-side pillar supporter from the ankle joint to take a bath or shower, and the like. Then, at the time when swellings around the ankle-joint malleolus lateralis and oppressive pains thereat had disappeared, the patients were instructed to mount or apply the inner-side pillar supporter to them only during their activities.

[0038] At a time three months later after being affected by the injury, it was possible to return the patients back to their original activity levels for all of the 10 minor-injury cases, and for 12 cases among the other 14 cases. No satisfactory results like these have been obtained by conventionally-available supporters.
