Description

DESCRIPTION
DISTAL FIBULA INTRAMEDULLARY NAIL
RELATED TECHNICAL FIELD
This invention relates to distal fibula intramedullary nail developed to be used in surgical therapy of the lower end fractures in fibula.
STATE OF THE ART
Fibula (calf bone) is the bone which is located in the lateral side of tibia (shinbone) and bonded to tibia from both top and bottom. Fibula has a thinner structure than most long bones.
The most frequently used method in the surgical therapy of fibula lower end fractures is osteosynthesis, which is performed with plate-screws. In this application, it requires big surgical incisions on the skin of the patient. As well as fractures, additional wounds on the soft-tissue also cause many problems posing difficulties with regard to the surgery such as delays in the surgery time and problems that may negatively affect the comfort of the patient such as wound skin problems, infection and the problems that may occur during the fracture healing.
Many apparatuses have been developed to be used in fibula treatment because of the problems mentioned above.
Among the most important ones are fibula nails. The invention No. 2014/13511 on “Fibula ivisi (Fibula Nail)” is an example of these structures. A nail structure consisting of a fibular pedicle that is used in the application process by securing it to the guide assembly and its main body being made up of titanium is described in the said invention.
In the fibula nails being currently used, there is no nail structure being capable of allowing for the technical applications that may be helpful for healing and may provide compression on the fracture line and for the techniques in the plate-screws applications which is not affected by the soft-tissue injuries and also being a gold standard treatment method.
However, distal fibula nails are applied rarely on the distal broken ends of the fibula. Its the most important reason is that there is less surgical experience due to its rare use because it is not a product routinely used in the treatment of these fractures in the market.
OBJECT OF THE INVENTION
The object of this invention is to enable the operation to be carried out by applying very small incision (skin cut) to the patient.
Another object of the invention is to provide successes for the closed surgical operations as well as open surgical operations by providing opportunity for the interfragmentary screw and compression screw applications in the fractures near the ankle joint.
Another object of the invention is to enable all the techniques in fracture fixation with plate-screw that may be applied by the open surgery by means of interfragmentary screw, syndesmosis screw and compression screw to be applied also with fibula nail.
Another object of the invention is to increase the patient comfort, to decrease infection risk, to accelerate wound healing and to enhance the success of the fracture treatment.
Another object of the invention is both to decrease the radiation exposure time of the patient and the surgical team by reducing the C-arm scopy use and to provide ease of application for the physician, which allows for a standard application by means of the guide used during the application.

DESCRIPTION OF THE INVENTION
Distal fibula intramedullary nail 1 of the invention comprises an integral distal fibula intramedullary nail 1 located in the fibula intramedullarily and such that it will allow for a suitable intervention according to the localization of the fracture, an ap guide 2 adapted to the distal fibula intramedullary nail 1 in order to provide fixation with a suitable screw by being pierced at a time by means of closed surgery method, enabling the holes of distal fibula intramedullary nail 1 present in the anteroposterior plan to be fixed and distal fibula intramedullary nail 1 to be locked and a lateral guide 3 enabling the holes of distal fibula intramedullary nail 1 present in the transverse plan to be fixed and distal fibula intramedullary nail 1 to be locked.
Distal fibula intramedullary nail 1 comprises an interfragmentary screw hole 1.1 in the distal fibula end fractures including two fracture lines in order to allow for an entire contact in the fracture line and increasing the contact in the fracture line by providing the application of interfragmentary screw 90° perpendicularly and preventing the displacement in the fracture line; a compression screw hole 1.2 enabling the compression screw to drive the nail by making distal fracture line move towards proximal end in the fracture fixation and enabling it to enhance the contact by providing compression in the fracture lines; a syndesmosis screw hole 1.2 securing fibula and tibia, thus enabling the structure named as syndesmosis to be stationary; and a lateral locking screw hole 1.4 where the lateral locking is performed.
Ap (anteroposterior) guide 2 comprises a compression screw hole 1.2 functioning as a guide for the passage of the compression screw to the compression screw hole 1.2 present in the distal fibula intramedullary nail 1 ; an ap locking screw guide hole 2.2 functioning as a guide for ap screw engagement; and an ap guide link rod 2.3 providing the engagement of the distal fibula intramedullary nail 1 and ap guide 2.
Lateral guide 3 comprises a syndesmosis screw guide hole 3.1 functioning as a guide for the passage of syndesmosis screw to the syndesmosis screw hole 1.3 present in the distal fibula intramedullary nail 1 ; a lateral locking screw guide hole 3.2 functioning as a guide for the lateral locking screw; and a lateral guide link rod 3.3 providing the connection between distal fibula intramedullary nail 1 and lateral guide 2.
Interfragmentary screw hole 1.1 , compression screw hole 1.2, syndesmosis screw hole 1.3 and locking screw hole 1.4 located in distal fibula intramedullary nail 1 are screw locking holes.
Distal fibula nail 1 may have a length in the range of 10 cm-17 cm and a diameter in the range of 6 mm-8 mm such that it will allow for a suitable interference in accordance with the patient and the localization of the fracture.
The rigid fixation may be performed for the fractures in the joint levels and the success for the closed surgery is achieved as in the case with the open surgery, by means of interfragmentary screw and compression screw applications in the fractures near the ankle joint by determining the length of distal fibula intramedullary nail 1 with a short size, if the fracture line is in the distal end of fibula. In more proximally located fractures, a longer distal fibula intramedullary nail 1 and a less rigid application will allow for obtaining a successful fracture healing that is aimed, because they are not in the joint levels.
Because the current treatment is the non-surgical methods in the fractures above the area of 17 cm, maximum length of distal fibula intramedullary nail 1 is designed to be 17 cm.
Ap guide 2 and lateral guide 3 comprises tunnels in order to provide fixation with suitable screws by piercing the screw locking holes at a time consisting of an interfragmentary screw hole 1.1 , a compression screw hole 1.2 and a syndesmosis screw hole 1.3 present in distal fibula intramedullary nail 1 by means of closed surgery method.
Piercing staff moving through these tunnels to the bones may pierce the bone cortices by passing through the interfragmentary screw hole 1.1 , compression screw hole 1.2, and syndesmosis screw hole 1.3 and provides both the attachment of the screws to the bone cortices and the stabilization required for the fracture fixation by passing through distal fibula intramedullary nail 1.
Distal fibula intramedullary nail 1 has been designed in order to be applied on the distal end fractures of the fibula bone. The peak point of the fibula is felt by means of hands and marked with a K-wire, while the patient is lying in the supine position. The accuracy of the marked point is confirmed by means of C-arm scopy. An entrance hole is pierced by an entrance piercing staff over the K-wire.
Fibula medulla is pierced by resilient and different sized piercing staffs through the entrance hole and through the fibula towards the proximal end and it is made suitable for the entrance of distal fibula intramedullary nail 1.
If the fracture fragments displace while the fibula is pierced intramedullarily, the operation may be performed much properly by using K-wire and the reduction clamps sent superficially such that they will not prevent the piercing process. The size of the distal fibula intramedullary nail 1 is determined by means of a metal ruler and C-arm scopy after the piercing process of the fibula. Distal fibula intramedullary nail 1 which is selected is moved through the entrance hole towards fibula medulla.
Distal fibula intramedullary nail 1 comprises housings in its distal end, where ap guide 2 and the lateral guide 3 will be adapted. Distal fibula intramedullary nail 1 is accommodated in these housings of ap guide 2 and lateral guide 3 and distal fibula intramedullary nail 1 is driven into the bone entirely.
Proceeding of distal fibula intramedullary nail 1 and the accommodation in the bone and the final situation of the fracture line is evaluated with C-arm scopy. In the next step, the bony tissue on the holes on distal fibula intramedullary nail 1 is screwed by drilling percutaneously by means of the locking holes on the ap guide 2 and the lateral guide 3 and distal intramedullary nail 1 is locked into the bone by means of screws.
After this locking process with screws, distal fibula intramedullary nail 1 is secured in the bone from different angles, thus the movements which may be occur in the fracture line are prevented. Then, ap guide 2 and the lateral guide 3 are removed and surgical operation is finalized by locking the distal housing with a top screw.
An integral fibula intramedullary nail 1 of the invention consists of an ap guide 2 and a lateral guide 3 which are adapted to distal fibula intramedullary nail 1.
The difficulty of use and the risk of complication to develop thereafter are decreased by means of this invention, even though there may be soft tissue problems.
Furthermore, the invention is designed so as to allow for the compression technique applied during the surgery. Thus, compression screw allows for less contact in the fracture ends and current gold standard methods may be applied without big incisions and by keeping less soft tissue damages with a closed surgery.
In this way, it may increase the patient comfort, decrease the infection risk, accelerate the wound healing and perform the fracture treatment successfully. Moreover, it allows for a standard and an easy application by means of ap guide 2 and lateral guide 3 use and it also decreases the radiation exposure of the patient and the surgical team by reducing the C-arm scopy use.
