Problems solved by technology

[0013] In addition, fastening plates can suffer from poor positioning, specifically because they are often difficult to place in place
This poor positioning not only impairs the stability of the implant, but also leads to the gradual loosening or even splitting of the implant under repeated mechanical stress

Embodiment Construction

[0033] figure 1 The skeleton of the human foot is shown, in this figure the first metatarsal 1 can be seen between the first phalanx 2 and the tarsus 3 of the great toe. Such as figure 1 As shown, the first metatarsal 1 is incised in its proximal portion 1A facing the tarsus 3 by lateral approach, for example for correction as figure 2 Deformation of the "valgus" type shown, which corresponds to an abnormal deflection angle α of the first metatarsal.

[0034] In the following description it is assumed that the first metatarsal has been osteotomized in its proximal part 1A, for example by dividing it into two bone fragments O1 and O2. In this case, the fastener implant according to the invention is intended to ensure the suturing of the two bone fragments O1 and O2 after the osteotomy has been performed. However, the fastener implant of the present invention is not limited to this type of application, and it may also be used for repairing fractures of the proximal portion o...

Abstract

The invention provides a fastener implant for osteosynthesis of fragments of the first metatarsal bone in its proximal portion situated towards the tarsal bone, the implant comprising at least a fastener element for fastening via a fastener face on or against the outside surface of the first metatarsal bone in order to hold the bone fragments together, wherein said fastener face includes at least one anatomical surface portion of shape that is substantially complementary to the shape of the plantar surface of the proximal portion of the first metatarsal bone.

Description

technical field [0001] The present invention relates to the general technical field of fastener implants for securing suturing of bone fragments, in particular two fragments of bone that have been severed or have been cut by osteotomy. [0002] The present invention relates more particularly to the technical field of devices and methods for the treatment of certain metatarsal pathological conditions, such as fractures or deformities of the great toe, in particular known by the scientific term "valgus". [0003] The present invention relates to a fastener implant for suturing fragments in the proximal portion of the first metatarsal towards the tarsus, the implant comprising at least one fastening element for fastening, for example by a fastening plate On or against the outer surface of the first metatarsal, and substantially on either side of the area of ​​separation between the bone fragments, thereby holding them together. [0004] The invention also relates to a method for...
