Abstract
Method and apparatus for reshaping an incurvated or distorted toenail for the purpose of alleviating conditions incident to the development of an ingrown toenail. The appliance and method provide for the straightening of the toenail through the application of an external force system to the nail surface producing the result that the lateral margins of the nail are caused to be removed and lifted from the soft tissues of the nail groove. The appliance consists of a pair of post members adhesively secured to the surface of the nail and one or more tensioned elastomeric members secured to the post members in a manner to cause a lifting and straightening force to be exerted on the nail.
Claims17
An apparatus for straightening an incurvated toenail comprising:
- a first post member adapted to be secured to only the external surface of such toenail, said first post member having a nail engaging portion and an upstanding portion;
- a second post member adapted to be secured to only the external surface of such toenail in spaced opposition to said first post member;
- a tension member under stress interconnecting said first post member and said second post member, said tension member being connected to said first post member at said upstanding portion, whereby,
- saidupstanding portion of said first post member defines a moment arm extending from the surface of such toenail thereby establishing a couple at such toenail providing a rotating force tending to straighten such toenail.

An appliance for an incurvated toenail comprising in combination:
- an elongated first post member defined by a bottom planar portion and a plurality of upstanding spaced apart generally vertical projections, the spaces between said projections defining grooves which taper outwardly;
- a second post member defined by a bottom planar portion and a plurality of upstanding spaced apart, generally vertical projections, the spaces between said projections defining grooves which taper outwardly;
- said first and second post member adapted to be adhesively secured to the surface of such nail at said planar portions;
- an elastomeric tension member interconnecting said first and second post members, said tension member being disposed in opposed grooves of said first and second post members;
- whereby,
- a couple is created at the nail surface, said couple defining a lifting force tending to straighten said nail and diminish the curvature thereof.

A method for shaping an incurvated toenoil comprising the steps of:
- a. providing a first post member having a bottom portion and an upstanding portion;
- b. providing a second post member having a bottom portion and an upstanding portion;
- c. providing an elastomeric tension member;
- d. adhesively securing said first post member directly to the external surface of such nail;
- e. adhesively securing said second post member directly to the external surface of such nail in spaced opposition to said first post member, said first and second post members being attached to only the external surface of such nail;
- f. elongating said elastomeric tension member;
- g. securing said elongated elastomeric member to said first and second post members;
- whereby,
- a couple is created at the nail surface, said couple defining a lifting force at said nail which tends to straighten said nail.

A method for shaping an incurvated toenail comprising the steps of:
- a. providing a first post member having a nail engaging portion and an upstanding portion;
- b. providing a second post member having a nail engaging portion;
- c. providing a tension member;
- d. adhesively securing said first post member to the external surface of such toenail;
- e. adhesively securing said second post member to the external surface of such toenail in spaced opposition to said first post member, said first and second post members being attached to only the external surface of such nail;
- f. attaching said tension member under stress to said first and second post members, said tension member being connected to said first post member at said upstanding postion;
- whereby,
- said upstanding portion of said first post member defines a moment arm extending from such toenail which establishes a couple thereby providing a rotational force at such toenail tending to straighten such toenail.
5 more elements
An apparatus for straightening an incurvated toenail comprising:
- a first post member adapted to be directly secured to the external surface of such toenail, without any portion thereof positioned below the surface of such toenail, said first post member being defined by a toenail surface engaging portion and an upstanding portion, said upstanding portion being defined by at least one generally vertical projection;
- a second post member adapted to be directly secured to the external surface of such toenail without any portion thereof positioned below the surface of such toenail in spaced opposition to said first post member, said second post member being defined by a toenail surface engaging portion and an upstanding portion, said upstanding portion being defined by at least one generally vertical projection;
- at least one tension member under stress interconnecting said first post member and said second post member, said tension member adapted to be secured to said upstanding portions of said first and second post members;
- whereby,
- said upstanding portions of said first and second post members define moment arms extending from the surface of such toenail, there being provided at each post member a rotational force acting on such toenail tending to straighten such toenail.
