- the locking nail also has a bend at the transition between a proximal partial section and a distal partial section. Disadvantageous in this known locking nail is the fact that it is difficult to introduce into the medullary space.
- the object of the present invention is to create a more advantageous locking nail for the repair of femur shaft fractures.
- a locking nail comprising a proximal nail section and a distal nail section adjoining the latter, with these nail sections having bores for the reception of bone screws, and with the distal nail section having a curvature extending in an anterior-posterior plane and corresponding substantially to the antecurvature of the femur; and with the proximal nail section having at least over a partial section a continuous curvature, in particular with constant radius of curvature, extending in a lateral-medial plane.
- continuous curvature will be understood in the following to mean that the curvature has no point with a discontinuity or a bend respectively, which can be mathematically described in such a manner that the first derivative of the curvature plot has no discontinuity or no jump-like change.
- the proximal nail section starting from the distal nail section, has a transition section and a securing section adjoining the latter with bores for the reception of the bone screws, with the transition section and the securing section having a continuous curvature with a constant radius of curvature.
- the locking nail in accordance with the invention is suitable in particular for the repair of femur shaft fractures, also in connection with trochanteric femur fractures, with the locking nail being manufactured with lengths of about 300 mm to 500 mm due to the inter-individually differing shaping of the femur.
- the locking nail is distinguished by a good mechanical hold in the medullary cavity and has a good rotational security.
- a transverse bore through which a bone screw is introduced in order to firmly hold the locking nail axially and in the direction of rotation is arranged in the lower distal nail section.
- the proximal nail section preferably has an inclined through-bore through which a femoral neck screw can be introduced.
- the locking nail in accordance with the invention is preferably designed as a continuous hollow tube, in particular as a cylindrical hollow tube and consists of a body-compatible, non corroding material such as titanium or a titanium alloy.
- a guide wire is preferably introduced into the continuous hollow tube.
- the locking nail could however also be designed in the shape of a bar and have no hollow inner space extending in the axial direction.

- the locking nail in accordance with the invention is designed in such a manner that the latter is preferably introduced into the femur or into its medullary space respectively starting from the trochanter major, with the introduction point being located slightly laterally with respect to the tip of the trochanter major.

In addition the trochanter major is more easily accessible in the activities required during the operation.
- a locking nail was usually introduced into the medullary space in the region of the fossa piriformis. Blood vessels etc.

This enables a locking nail to be formed with a smaller total cross-section, which has an advantageous effect on the introduction into the medullary space and in addition requires only a small opening of the operation field.
- the locking nail which is known from the cited reference has at the transition location between the distal and the proximal nail section a bend location and is therefore difficult to introduce into the medullary space in spite of the elasticity produced by the longitudinal slit in the distal nail section since the medullary space has a curved extent and this nail lies in contact at certain locations at the medullary space wall or at the spongiosa and can be introduced into the medullary space only with a greater exertion of force.

- the locking nail in accordance with the invention has the property that the latter rotates into the correct final position by itself during the introduction into the medullary space since the outer shape of the locking nail is formed in imitation of the shape of the medullary space with respect to essential aspects.
- the locking nail which is known from the cited reference has a bend at the transition location between the proximal and distal nail section, which prevents a rotation of its own accord during the introduction into the medullary space.
- the locking nail which is known from the cited reference has the further disadvantage that the nail which is introduced into the medullary space is only rotatable to a limited extent since material protrudes into the longitudinal slit and forms an obstacle during the rotation. Since the locking nail in accordance with the invention does not necessarily require a longitudinal slit, it can also be manufactured more economically.
- the locking nail in accordance with the invention can have a low elasticity and nevertheless be surely introduced without a greater exertion of force into the medullary space.
- a greater force which is directed approximately radially outwardly and in particular weakens or destroys the femur corticalis, is avoided during its introduction into the medullary space.
- the femur is held together in its anatomically correct position.
- an unfavourably designed locking nail can cause the femur having the fracture to adapt to the shape of the locking nail, which has the result that the fixed femur has a faulty position or a deviation from the normal position respectively.

Abstract
Description
- The invention relates to a locking nail for the repair of femur shaft fractures, also in connection with trochanteric femur fractures, in accordance with the preamble of
claim 1. - An osteosynthetic aid for the repair of intertrochanteric or subtrochanteric femur fractures which is designed as a locking nail with an open cloverleaf profile is known from the reference EP 0 528 128. The locking nail has inclined bores in its proximal section for guiding and holding a femoral neck screw. The locking nail has an axial longitudinal slit at its distal section. The locking nail also has a bend at the transition between a proximal partial section and a distal partial section. Disadvantageous in this known locking nail is the fact that it is difficult to introduce into the medullary space.
- The object of the present invention is to create a more advantageous locking nail for the repair of femur shaft fractures.
- This object is satisfied by a locking nail having the features of
claim 1. Subordinate claims 2 to 13 relate to further, advantageous embodiments of the locking nail in accordance with the invention. - This object is satisfied in particular by a locking nail comprising a proximal nail section and a distal nail section adjoining the latter, with these nail sections having bores for the reception of bone screws, and with the distal nail section having a curvature extending in an anterior-posterior plane and corresponding substantially to the antecurvature of the femur; and with the proximal nail section having at least over a partial section a continuous curvature, in particular with constant radius of curvature, extending in a lateral-medial plane.
- The term “continuous curvature” will be understood in the following to mean that the curvature has no point with a discontinuity or a bend respectively, which can be mathematically described in such a manner that the first derivative of the curvature plot has no discontinuity or no jump-like change.
- In an advantageous embodiment the proximal nail section, starting from the distal nail section, has a transition section and a securing section adjoining the latter with bores for the reception of the bone screws, with the transition section and the securing section having a continuous curvature with a constant radius of curvature.
- The locking nail in accordance with the invention is suitable in particular for the repair of femur shaft fractures, also in connection with trochanteric femur fractures, with the locking nail being manufactured with lengths of about 300 mm to 500 mm due to the inter-individually differing shaping of the femur. The locking nail is distinguished by a good mechanical hold in the medullary cavity and has a good rotational security. A transverse bore through which a bone screw is introduced in order to firmly hold the locking nail axially and in the direction of rotation is arranged in the lower distal nail section. The proximal nail section preferably has an inclined through-bore through which a femoral neck screw can be introduced.
- The locking nail in accordance with the invention is preferably designed as a continuous hollow tube, in particular as a cylindrical hollow tube and consists of a body-compatible, non corroding material such as titanium or a titanium alloy. A guide wire is preferably introduced into the continuous hollow tube. The locking nail could however also be designed in the shape of a bar and have no hollow inner space extending in the axial direction.
- An advantage of the locking nail in accordance with the invention is the fact that the latter can be introduced into the medullary space of the femur without a greater exertion of force even in an embodiment with low elasticity. The embodiment with low elasticity ensures a very good mechanical hold and a good support function in the medullary cavity.
- The locking nail in accordance with the invention is designed in such a manner that the latter is preferably introduced into the femur or into its medullary space respectively starting from the trochanter major, with the introduction point being located slightly laterally with respect to the tip of the trochanter major. Since the trochanter major is arranged closer to the surface of the skin in comparison with the previously usual introduction location at the femur, the introduction via the trochanter major has the advantage that a smaller opening of the operation field is required, which in particular reduces the danger of infections. In addition the trochanter major is more easily accessible in the activities required during the operation. A locking nail was usually introduced into the medullary space in the region of the fossa piriformis. Blood vessels etc. are also present at this location, however, so that the introduction via the trochanter major is more sure to avoid damage to these blood vessels. In an advantageous embodiment the locking nail has a securing section with a relatively small cross-section. This enables a locking nail to be formed with a smaller total cross-section, which has an advantageous effect on the introduction into the medullary space and in addition requires only a small opening of the operation field.
- The locking nail which is known from the cited reference has at the transition location between the distal and the proximal nail section a bend location and is therefore difficult to introduce into the medullary space in spite of the elasticity produced by the longitudinal slit in the distal nail section since the medullary space has a curved extent and this nail lies in contact at certain locations at the medullary space wall or at the spongiosa and can be introduced into the medullary space only with a greater exertion of force. The locking nail in accordance with the invention with the curved proximal nail section has the advantage that the latter takes into account the anatomical shape of the medullary space in such an advantageous manner that it can be introduced without a greater exertion of force. In contrast to short locking nails, the locking nail in accordance with the invention, which is designed to be very long, must be rotated during the introduction into the medullary space by a partial rotation about its longitudinal axis. The locking nail in accordance with the invention has the property that the latter rotates into the correct final position by itself during the introduction into the medullary space since the outer shape of the locking nail is formed in imitation of the shape of the medullary space with respect to essential aspects. The locking nail which is known from the cited reference has a bend at the transition location between the proximal and distal nail section, which prevents a rotation of its own accord during the introduction into the medullary space. The locking nail which is known from the cited reference has the further disadvantage that the nail which is introduced into the medullary space is only rotatable to a limited extent since material protrudes into the longitudinal slit and forms an obstacle during the rotation. Since the locking nail in accordance with the invention does not necessarily require a longitudinal slit, it can also be manufactured more economically.
- The locking nail in accordance with the invention can have a low elasticity and nevertheless be surely introduced without a greater exertion of force into the medullary space. Through the design of the locking nail in accordance with the invention a greater force, which is directed approximately radially outwardly and in particular weakens or destroys the femur corticalis, is avoided during its introduction into the medullary space. Through this it is also enabled that the femur is held together in its anatomically correct position. It is known that an unfavourably designed locking nail can cause the femur having the fracture to adapt to the shape of the locking nail, which has the result that the fixed femur has a faulty position or a deviation from the normal position respectively.
- Exemplary embodiments of the locking nail in accordance with the invention will be explained in the following in more detail with the help of the drawings. Shown are:
- FIG. 1 a side view of the locking nail from the direction B;
- FIG. 2 a front view of the locking nail from the direction A;
- FIG. 3 a front view of the locking nail, which is rotated slightly about its axis, from the direction C, partly in section;
- FIG. 4 a detail view of the proximal nail section from the direction D;
- FIG. 5 a detail view of the locking nail from the direction E;
- FIG. 6 a cross-section through a slit locking nail;
- FIG. 7 a detail view of the securing section from the direction F.
- The
locking nail 1 in accordance with FIG. 1 is formed in a single piece and consists of aproximal nail section 2 and adistal nail section 3 adjoining at the latter. Starting from theproximal end 1 a of thelocking nail 1 theproximal nail section 2 comprises athread section 2 c extending in a straight line and having aninner thread 2 d, adjoining thereat asecuring section 2 b which has atransverse bore 2 i, an ovaltransverse bore 2 h and twoinclined bores transition section 2 a which extends conically contracting to thedistal nail section 3. The surface of the securingsection 2 b has agroove 2 g extending parallel to theinclined bores inclined bores groove 2 g in order to secure the femur head. For this purpose an aiming device or a hammering-in tool is preferably used which is temporarily screwed into theinner thread 2 d of thethread section 2 c when thelocking nail 1 is inserted into the femur in order to be able to screw in the bone screw with an exact guidance. - Adjoining at the
transition section 2 a thedistal nail section 3 extends up to thedistal nail end 1 b. The centre line 1 c which extends in the middle of thelocking nail 1 is illustrated between theproximal nail end 1 a and thedistal nail end 1 b. The anterior-posterior plane apE extends corresponding to the plane of view in accordance with FIG. 1. Thedistal nail section 3 has a curvature which extends in this anterior-posterior plane apE and which is substantially designed corresponding to the antecurvature of the femur. The curvature of thedistal nail section 3 or of its middle line 1 c is preferably designed as a circular segment, with the radius of curvature R1 amounting to for example 2 meters depending on the anatomical form of the femur.Transverse bores transverse bore 3 c are placed in thedistal nail section 3 for the reception of bone screws. - In FIG. 1 the lateral-medial plane lmE, which extends perpendicularly to the plane of view or to the anterior-posterior plane apE respectively, is also illustrated. The lateral-medial plane lmE extends corresponding to the plane of view in accordance with FIG. 2. In FIG. 2 the anterior-posterior plane apE, which extends perpendicularly to the plane of view or to the lateral-medial plane lmE, is also illustrated.
- The front view of the
locking nail 1 from the direction A in accordance with FIG. 2 shows thedistal nail section 3, which extends in a straight line in the lateral-medial plane lmE from this point of view and at which the two, thetransition section 2 a and the securingsection 2 b, having a common curvature with a constant radius of curvature R2, adjoin. The followingthread section 2 c is designed in the illustrated exemplary embodiment to extend in a straight line, but could however also be designed to extend curvilinearly and in particular have the same radius of curvature R2. Thepartial section locking nail 1, and preferably over about a third of its total length. - The detail view illustrated in FIG. 4 from the direction D shows a part of the
proximal nail section 2, namely the securingsection 2 b and thethread section 2 c. In thesecuring section 2 b the openings of the first and secondinclined bore notch 2 g and a part of the ovaltransverse bore 2 h can be seen. In addition theproximal nail section 2 has twonotches 21 at theproximal nail end 1 a. Thenotches 21, theinclined bores transverse bore 2 h all extend in the same plane S2. As can be seen in FIG. 3 thecentre lines inclined bores notch 2 g also extending parallel to theinclined bores inclined bores - FIG. 7 shows a plan view from the direction F onto a segment of the securing
section 2 b withinclined bores centre lines screw 6 with a centre line 2 n is arranged in the ventrally arrangednotch 2 g. In the illustrated exemplary embodiment thecentre lines centre lines nail 1. The distance between thecentre lines 21, 2 n and thecentre lines 2 m, 2 n amounts for example to 8 mm. Theproximal nail section 2 is firmly connected to the femur by one, two or threescrews 6 which are arranged to pass through the twoinclined bores notch 2 g. This arrangement of twoinclined bores notch 2 g has the advantage that the diameter of theproximal nail section 2 can be designed relatively thin and nevertheless a secure anchoring of the lockingnail 1 by means ofbone screws 6 is possible. The lockingnail 1 can for example be designed in such a manner that theproximal nail section 2 has a diameter between 13 and 15 mm and thedistal nail section 3 has a diameter between 9 and 13 mm. A lockingnail 1 which is designed to be so thin has the advantage that it requires only a small opening of the operation field for its implantation. Thus a lower danger of infection is present during the implanting due to the small skin opening required. The securingsection 2 b withinclined bores notch 2 g, in particular in accordance with the embodiment illustrated in FIG. 4 and FIG. 7, could also be used separately from theother parts distal nail section 3 in a differently designed locking nail. A securingsection 2 b of this kind could also be designed to extend in a straight line or curvilinearly respectively in the axial direction. FIG. 5 shows a front view of theproximal nail end 1 a from the direction E. Starting from theproximal nail end 1 a the lockingnail 1 extends along theproximal nail section 2 in a left curve and extends after the transition to thedistal nail section 3 in a downwardly pointing curve. A plane S1 extending in the direction of view perpendicularly through thedistal nail section 3 and the plane S2 extending through thenotches 21, theinclined bores transverse bore 2 h intersect at an angle of 78 degrees. Theproximal nail section 2 thus has an anteversion of 78 degrees with respect to thedistal nail section 1. This anteversion is required in order that theinclined bores transverse bore 2 h respectively extend in the direction of the femur neck or of the femur head respectively when the lockingnail 1 is inserted in the femur. The anteversion amounts preferably to between 75 degrees and 80 degrees, depending on the anatomical form of the femur. The German term “Antetorsion” is called “anteversion” in English. - FIG. 3 shows the locking
nail 1 from the direction of view C, which extends perpendicularly to the plane S2. Relative to the illustration in accordance with FIG. 2 from the direction of view A the lockingnail 1 is illustrated in accordance with FIG. 3 to be rotated by 12 degrees about its longitudinal axis. The plane of intersection through theproximal nail section 2 corresponds to the plane S2 and extends parallel to the plane of view. - FIG. 6 shows a section through a further exemplary embodiment of a
distal nail section 3 having agap 5 which extends in its longitudinal direction in order to lend a higher elasticity to thenail section 3. - The locking
nail 1 illustrated in FIGS. 1 to 5 is intended for a left femur. As a result of the physiological antecurvature and anteversion of the femur a right and left version of the lockingnail 1 are required.
