Description

Syndesmosis Plate and Screw System Used in Tibia, Talus and Fibula Bone
Deformations
Technical Field The invention relates to syndesmosis plate and screw system used to treat the bone deformations of the tibia, talus and fibula in the ankle region.
Prior Art
The plates used to treat the bone deformations in the tibia, talus and fibula in the ankle region are called syndesmosis plates. Syndesmosis plates cannot be used in all fracture types in general. Because conventional plates are in full contact with the bone at the fracture region and the applied screws pull the bone towards the plate. Compression of the bone surface and extensive interventional surgical approach during its applications adversely affect the blood circulation of the fracture site and thus the biology of fracture healing.
Since the syndesmosis plates and endobutton used in ankle deformations are used independently, the anatomical structure is deteriorated. In addition, the groove heights of the screw systems used in conventional plates are higher than the locking screw systems, and the body thickness is less. Due to the height differences mentioned, the holding power of the screws to the bone is less.
In the plates used in prior art, the fracture region is in full contact with the bone. For ankle fractures to heal, blood supply to the bone is required. The full contact with the bone prevents the blood supply to the bone and slows down the healing process. In the traditional plating technique, syndesmosis plates are placed with large incisions during the surgical operation. The inability to use small incisions causes problems such as union and infection after surgical treatment of fractures.
Distal posterior lateral tibial anatomical locking bone plate is mentioned in the Chinese utility model document CN209789984 in the prior art. The bone fracture plate in the mentioned utility model document has an integrated structure and includes a transverse part. The transverse part has a chamfered quadruple structure. The transverse portion is matched with the anatomical structure of the posterior side of the proximal end of the tibia. There is no endobutton hole in the said bone plate.
Purpose of the Invention
The purpose of the invention is to obtain a syndesmosis plate and screw system that provides blood circulation and faster healing of the bone by keeping the contact with the bone at a minimum level in ankle fractures.
Another purpose of the invention is to ensure that all types of fractures in the ankle can be intervened with a single plate.
Another purpose of the invention is to ensure endobutton attachment without defect in the anatomical structure.
Another purpose of the invention is to obtain a fully anatomical syndesmosis plate.
Another purpose of the invention is to obtain a syndesmosis plate with combined holes on it for the placement of locking or non-locking screws.
Another purpose of the invention is to obtain a syndesmosis plate that can be used in all fractures of the epiphysis and metaphysis from the distal end of the fibula to the diaphysis.
Another purpose of the invention is to obtain a syndesmosis plate with special channels and screws on which the endobutton can fit. Another purpose of the invention is to obtain a syndesmosis plate with increased strength.
The syndesmosis plate system developed to achieve the mentioned purposes include locking screws (20) with locking grooves (23) consisting of 3.5 locking screws (21) and 2.7 locking screws; non-locking screws (30) consisting of 4.5 non locking screws (31), 3.5 non-locking screws (32) and 2.7 locking screws (33); locking screw holes (40) containing 3.5 locking screw holes (41) and 2.7 locking screw holes (42) through which said locking screws (20) pass; non-locking screw holes (50) containing 3.5 non-locking screw holes (51), 4.5 non-locking screw holes (52) and 2.7 non-locking screw holes (53) through which said non-locking screws

Explanation of the Invention
The invention relates to syndesmosis plate (10) and screw systems used to treat the bone deformations of the tibia, talus and fibula in the ankle region.
Syndesmosis plate (10) system subject to the invention includes locking screws (20) with locking grooves (23) consisting of 3.5 locking screws (21) and 2.7 locking screws; non-locking screws (30) consisting of 4.5 non-locking screws (31), 3.5 non locking screws (32) and 2.7 locking screws (33); locking screw holes (40) containing 3.5 locking screw holes (41) and 2.7 locking screw holes (42) through which said locking screws (20) pass; non-locking screw holes (50) containing 3.5 non-locking screw holes (51), 4.5 non-locking screw holes (52) and 2.7 non-locking screw holes (53) through which said non-locking screws (30) pass; endobutton holes (60) and recesses (70). The 4.5 non-locking less screw (31) is also known as the non-locking spongious screw. It has larger diameter and length than other screws. Said 4.5 non-locking screws (spongious screws) (31) are used to connect the fibula and tibia bones.
Syndesmosis plate (10) subject to the invention is manufactured from the material Ti6A14V ELI (Grade 23). Thanks to the mentioned material Ti6A14V ELI (Grade 23), the yield and elongation values of the syndesmosis plate (10) are high. With the increase in yield and elongation values, the strength of the syndesmosis plate (10) increases. Yield and percent elongation values are 1.5 times higher than the Ti 4 material used in other products. Considering the yield value and percent elongation value, more strength is provided.
With the syndesmosis plate (10) subject to the invention, all types of fractures in the ankle can be treated with a single plate. In addition, since the syndesmosis plate (10) is taken as reference when connecting the endobutton, no abnormalities in the anatomical structure occur. Said connecting process is done through the endobutton hole (60) located on the syndesmosis plate (10).
The syndesmosis plate (10) and screws in the screw system (20, 30) subject to the invention are applied as a locking screw (20) or a non-locking screw (30) in accordance with the anatomy of the ankle. Said screws (20, 30) are also applied in different diameters and angles according to the thickness of the bone tissue in the ankle joint region.
All the locking screws (20) carry the load as a whole, not one by one, against the stripping of the syndesmosis plate (10) subject of the invention. Bone-screw contact is greater in locking screws (20). In bone fractures with low bone quality, syndesmosis plate (10) systems using locking screws (20) are more reliable than conventional plates.
Since the syndesmosis plates (10) are angularly stable, they can resist deforming forces for a long time. Because angular stability is the main feature of locking plates. Syndesmosis plate (10) system is applied on the fracture as follows:
An incision is made in the ankle fracture region.
The region opened on the ankle is fixed with the help of a hand tool.
Bruno tendons are checked to avoid anatomical loss.
A hole is made in the distal fibula with a 5 mm drill using the anatomical locking system.
Non-locking screws (30) (secondary) are inserted into the bone.
Then the syndesmosis plate (10) is positioned over the fracture.
With the help of a drill, the locking screws (20) fix the syndesmosis plate (10) to the bone.
Said locking screws (20) are tightened to ensure adequate locking and excellent stability is achieved.
The endobutton is tied with reference to the endobutton holes (60) (cones) on the syndesmosis plates (10). In this way, the bones are finally fixed.
To increase the biocompatibility of the syndesmosis plate (10) surface and its passivity against the tissues, anodic oxidation is applied.
Since the syndesmosis plates (10) are taken as reference while the endobutton is connected, no abnormalities in the anatomical structure will occur. In addition, there are special endobutton holes (60) on the syndesmosis plate (10) for the endobutton to be attached to.
Syndesmosis plates (10) are fully compatible with the bone-anatomy structure. Compatibility with the anatomy of the ankle is provided to syndesmosis plates (10) thanks to the advantage of applying a locking screw (20) or a non-locking screw (30). Said screws (20, 30) can be applied in different diameters and angles depending on the thickness of the bone tissue in the ankle joint region.
In the system subject to the invention, locking screws (20) with optimum diameters of 3.5 mm and 2.7 mm and non-locking screws (30) with optimum diameters of 3.5 mm, 2.7 mm and 4.5 mm are preferred. In alternative embodiments of the invention, the diameters of the screws with optimum values may vary.
In the system subject to the invention, 4.5 nondocking screws (31) of large size and diameter fit into 4.5 non-locking screw holes (52) on the syndesmosis plate (10). Said 4.5 non-locking screws (31) and 4.5 non-locking screw holes (52) are used to connect the bones fibula and tibia.
All the locking screws (20) and non-locking screws (30) in the system subject to the invention are used. Locking screws (20) are fixed on the syndesmosis plate (10) via locking screw holes (40). Non-locking screws (30) are attached to the syndesmosis plate (10) through non-locking screw holes (50). There are grooves in the locking screw holes (40) to enable the locking screws (20) to be fixed.
Locking screws (20) contain locking grooves (23) that enable them to be locked into the screw slot on the syndesmosis plate (10) over the screw head. The use of locking screws (20) reduces the pressure on the bone. In addition, the groove heights are less than the non-locking screws (3), and the body thicknesses are greater. Due to the mentioned features, the locking power of the locking screws (20) is higher. Locking screws (20) increase the bone holding power of the system subject to the invention in general.
Locking screws (20) lock the syndesmosis plate (10) for its attachment to the broken bone. The locking process is achieved by tightening the locking grooves (23) on the screw head into the screw hole on the syndesmosis plate (10). Non-locking screws (30) are also used for the attachment of the syndesmosis plate (10) to the bone. However, since the syndesmosis plate (10) is fixed to the bone in locking screw (20) systems, the anatomical structure is preserved.
There are recesses (70) on the edges of the syndesmosis plate (10) to reduce the contact area of the mentioned syndesmosis plate (10) with the bone. While the pressure on the bone membrane with the recesses (70) decreases, the healing process accelerates. In addition, the mentioned recesses (70) provide the physician with ease of bending so that the syndesmosis plate (10) is placed in full compliance with the patient's bone.
There are combined holes (80) in some of the non-locking screw holes (50) and the locking screw holes (40) on the syndesmosis plate (10) in the system subject to the invention. One side of the mentioned combined holes (80) is grooved, and the other side is non-grooved. The grooved side is left to send the locking screws (20), and the other side is left to send the non-locking screws (30). Thanks to the combined hole (80), it is possible to send different screws to the physician from the same location. Locking screws (20) can only be sent vertically to the syndesmosis plate (10). Since it is locked, the syndesmosis plate (10) does not press against the bone and reduces the existing pressure. However, physicians can send non-locking screws at different angles (+35°) when they want the syndesmosis plate (10) to fit on the bone.
