DESCRIPTION:
BRIEF SUMMARY
TECHNICAL DOMAIN
The invention concerns the technical domain of articular mobilization with a view to the orthopaedic correction of the foot.
The apparatus makes it possible to mobilize the osteo-articular assembly constituted by the foot in the three perpendicular planes in space (FIG. 1).
It allows:
1) flexion-extension of the ankle about axis AA',
2) varus-valgus of the talocalcanean joint about axis BB',
3) abduction-adduction about axis CC'.
This apparatus is particularly intended for the continuous passive mobilization of talipes equinus in the new-born baby.
Talipes equinus is a deformation of the foot consecutive to an intra-uterine malposition. According to Professor Ombredanne's analysis, the deformation of the talipes equinus is effected in the three perpendicular planes in space, as illustrated for a left foot in FIGS. 2 to 7.
1) in the saggital (or antero-posterior vertical) plane, the foot is deformed in EQUINUS (FIG. 2), i.e. the whole of the foot pivots in plantar flexion with respect to the leg to form a forwardly open sine obtuse angle.
2) in the frontal plane, the foot is deformed in VARUS, i.e. the sole of the foot faces the median axis of the body (FIG. 3).
3) in the horizontal plane, the foot is deformed in ADDUCTION (FIG. 5), i.e. its longitudinal (antero-posterior) axis is directed towards the median axis of the body.
All things considered, using the metaphor of a boat, the talipes equinus pitches, rolls and veers.
PRIOR ART
So-called mechano-therapy apparatus are known which allow the active or activo-passive mobilization of the foot in the three perpendicular axes in space (so-called FRANCO apparatus).
This apparatus does not come within the concept of continuous passive articular mobilization.
The originality of the apparatus according to the invention resides in its capacity of conducting a continuous passive mobilization of the foot in:
1) isolated valgus-varus (axis BB' FIG. 1),
2) valgus-varus concomitant with abduction-adduction (axis BB' and CC' FIG. 1),
3) isolated dorsal flexion-plantar flexion (axis AA' FIG. 1),
4) dorsal flexion-plantar flexion concomitant with the valgus-varus (axis AA' and BB' FIG. 1),
5) dorsal flexion-plantar flexion concomitant with the valgus-varus and with the abduction-adduction (axes AA', BB' and CC' FIG. 1),
6) isolated abduction-adduction (axis CC' FIG. 1).
In summary, the three axes of deformation may be mobilized separately or simultaneously.
The object of the invention is to provide such an apparatus which makes it possible to effect the orthopaedic correction of this trouble by fighting against the deformation.
From the therapeutic point of view, the orthopaedic correction of this trouble consists in fighting against:
1) supination of the fore-foot and of the rear foot, and which is the resultant of varus and adduction.
2) equinus: the apparatus makes it possible to correct the first deformation by mobilizing the foot in pronation (=valgus+abduction) and the second deformation by mobilizing the foot in dorsal flexion (axis AA' FIG. 1).
The apparatus makes it possible to correct one or the other deformation or the two simultaneously.
STATEMENT OF THE INVENTION
In order to attain the above objectives, the apparatus according to the invention is characterized in that it comprises on a foot base, on the one hand, an articulated sole system comprising a sole borne by supports articulated to give said sole three degrees of orientation adjustable on the orthogonal axes of flexion, of abduction-adduction and of varus-valgus, on the other hand, a drive member of the rotating type and, furthermore, a transmission system incorporating adjustable rods connecting the drive member to the articulated sole system.
Various other characteristics will appear from the following description made with reference to the accompanying drawings which show, by way of non-limiting examples, embodiments of the object of the invention.
