Abstract

Whenever placement of 95° angled plates is indicated in orthopedic surgery, the plate is frequently misaligned in relation to the bone due to the fact that there is no instrument to accurately and reliably guide the guide nail when it is initially introduced since current techniques and instruments are only visual. The inventive implant is precisely indicated for the treatment of certain femur fractures. To solve the above-mentioned problem, a guide plate comprising two main components is provided: 1.- The main male plate, on which bone fragments are reduced in a coherent and safe manner, shows beforehand the position the definitive implant will adopt thereby solving the problem of plate-bone misalignment. 2.- The dismountable female plate together with the above-mentioned plate form a tunnel for the guide chisel thereby solving the problem of plate nail alignment and enabling visualization of the exact position of the definitive implant by placing the implant through the guide plate while preserving alignment of the bones and remaining in correct position.

Description

GUIDE PLATE PLATES angulated 95 ° ORTHOPEDIC SURGERY. Background.

To date, the practice of Orthopedic Surgery for placement of angulated plates 95 ° when the implant is indicated, we as an orientation aid instruments designed by Swiss Association for the Study of Internal Fixation (AO). basically it is these; the guiding angle (KT5 catalog AESCULAP) nail guide (KT20 cat. AESCULAP) and guide pin (KT22 cat. AESCULAP). With the technique described in AO manual osteosynthesis, this orientation is only visual order. So the exact positioning of the implant is difficult, resulting in a large percentage of cases poor orientation of the plate. As some surgeons have opted not to use the angled plates 95 °, particularly believe it is a good implant for some femur fractures. The problem lies in that it is initiated by placing the nail, and by not having an instrument that we accurate orientation, this is with a deviation of one to several degrees, which affects the final position of the plate in a bad this alignment relative to the bone surface. In order to solve the problem described a tool of the same material of the above mentioned that guarantees precise positioning of the angled plates 95 °, first stabilizes the fracture and showing in advance the position will have the plate ideo and nail final implant; which we have called PLATE - GUIA and consists of two basic components. 1. Main core (# 1, Figure 1) .2.- female assembly (No. 2, Figures 1), and be protected by this application since no other with these characteristics we solution an accurate, safe and effective to the problem described above. I being the main advantage of the new instrument.

Description of the Invention.

The details and features of the guide plate, shown clearly in the following description and drawings of Figures 1 to 4.

The guide plate comprises essentially two components and

5 described as: 1. Main component core (# 1, Figure 1) and 2.-

Female component assembly (No.2, Figure 1).

The main male component (No.l) comprises a condylar plate 10 holes with features and arrangement thereof to auto compression which is separated nail foil and place in the 0-angle end soldier has a plate perpendicular to this, 2.5 mm sense. thick, U-shaped square (# 3, Fig 1), 30mm. long X 16 mm. wide and 6.5 mm. high on its internal surface, and at the ends of its vertical branches have an eyebrow 2.5mm. (# 4, Fig 1) to the outside and that run the full length 5 and end at a proximal end welded to the condylar stop plate (No 5, Fig 1).

The female component assembly (No 2, Fig 1) whose shape is a square C of 30 mm. long X 16 mm. in the opening of its branches which mirror assembled with the main part and with it or form a cube whose light (No 6, Figure 1) of 30mm. X 16 mm. X 6.5mm. which serve to accommodate the chisel guide (KT22, cat. AESCULAP) and whose direction is given by the orientation of said attachment that is input at 85 ° to the main axis of the guide plate and output 95 ° angle complementary to the previous (No. 7, fig. 1). Said female component 5 (No 2) has on its outside two ducts and distal face 1.5mm. in diameter (No. 8 Figure 1) that run in parallel along the 30mm. centered and separated by 16 mm .. In between said conduits at its proximal portion to the junction with the plate has a recess 6mm. Radio (No. 9 of FIG. 1) and on the opposite side a ridge of 6mm. high by LOMM. long and 3mm. wide (No. 10 fig.l) and when assembling the two pieces male-female instrument shown in Figure No. 2 is formed by what we have called

Guide plate.

Method for using the guide plate.

Femur fractures; intertrochanteric, subtrochanteric, supracondylar (No 11, Fig 5) and osteotomies in the same regions and whose osteosynthesis angular plates 95 ° is used, with the familiar and exposed bone fragments (No 12, Fig surgical techniques 5), with the guide plate assembled (figures 3 and 4), this will serve as support to reduce anatomically said fractures (figure 5), which gives a great advantage to method previously known, and placing the guide plate in the appropriate position (No 1, Fig 5) the two Kirschner brads or Steinmann 1.5mm passed. (No 13, Fig 6), the ducts having the female assembly and passing them through the entire bone (No 14, fig. 6) which allows direct visualization of the position and direction will follow the guide pin (KT22 ), can currently make corrections to the case if needed, as well as passing screws (No 15, Fig 6) if necessary to give greater strength to the system because the arrangement of the holes is the same as that of angulated plates these screws serve for the definitive implant, another advantage to the method previously used. If everything is correct the brads are removed and proceeds to the introduction of the guide KT22 (No 16, Fig. 7) nail can control the depth required by the recess assembly (No. 9, Fig. 7) is removed nail guide and screws where they are used with the guide plate, and the final implant, angled plate 95 ° (No 17, Fig 8), mounted in the exhaust impactor KT26, Cat. AESCULAP ​​(No 18, Fig 8 ) proceeds to the introduction thereof (Fig. 8) through the hub light guide plate which ensures that occupy the exact position thereof, and to the extent permitted this. (Fig.9), in this time the female component (No 2, Fig 9) pulling crest (No 10, Fig.9) is removed, and sliding the male core component (No 1) to the front face of the bone (Fig.10) maintaining; this position with clips reduction finishes entering the final implant (No 17, Fig.l 1) being this in the correct position is fixed with screws (not 15) the bone.

Claims

Claims.
Having sufficiently described my invention, I consider as a novelty and therefore claim as my exclusive property the content of the following clauses: 1. guide plate for angle plates 95 °, in orthopedic surgery, that comprise two basic components; .1.- main male and female assembly 2..
The main male component is formed by an angular plate 95 ° 10 holes auto compression to which has been withdrawn nail foil, leaving only the plate which is characterized by an attachment which has soldier at the end angular and perpendicular thereto, said attachment consisting of a plate-shaped square U in its vertical branches have an eyebrow or rim towards the outer side that run the full extent terminating in a proximal stop to the junction with the plate angulated.
The component female assembly whose shape is a square C and its branches assembled mirror eyebrows male component already described, and together with this form a tunnel serving to receive the guide chisel in a way that between 85 ° with respect to the main axes plate - attachment and output corresponding to the sheet nail implant angular 95 ° 95 ° angle, which ensures that there will be variation in the end plate-nail position. The component female assembly has at its outer face two conduits that run in its entirety and serve to accommodate the guides clavillos Steinmann, that will give us the orientation of the guide chisel, among these conduits at the proximal end to the plate It has a recess that serve to control the depth of guide chisel in the opposite end has a ridge used to manipulate
