DESCRIPTION
A CLAMPING PLATE HAVING A SCREW THROUGH WHICH BONE CEMENT CAN BE INJECTED FROM
Technical Field
This invention is related to a clamping plate to be used in humerus operations, having a screw through which bone cement can be injected from, in order to ensure the fixation of the plate at the position it has been placed on and which is used in order to fix the locking-clamping plates that have been attached onto the humerus.
Prior Art
The separation of the bone that may occur due to external or internal forces is called breaking. The case of breaking of the bone, may be a fracture or it may lead to several broken bones relating to the shock absorbing capability of the bone and the degree of the forces that affect the breaking of the bone.
A bone named humerus is present between the forearm and the shoulder of humans. The breakages that may occur in this humerus may occur from direct impact or axial forces towards the elbow. Besides this, the humerus may also break due to old age. A method of treating the breaking of the humerus may be a plaster cast. Some types of humerus breakages are treated with surgical methods. Frequently plate screw method is preferred during orthopedic surgical treatment processes. In some cases surgical treatment is applied using cylindrical shaped titanium screws. However, this structure that has been placed using a surgical operation, may change position or location in time due to the fact that the bone structure it has been placed on is mobile. The screw may become worn and it
may start moving inside the bone. As a result the patient may have to be re- operated on.
A pedicle screw which enables the injection of cement there-through and which has a cannula located at the centre is described in the WO2009029056 numbered international patent application document, of the known state of the art.
Aims of the Invention The aim of the invention is to provide a clamping plate having screws through which bone cement can be injected from, used in fixing the locking clamping plates onto the humerus.
Another aim of the invention is to provide a clamping plate having screws through which bone cement can be injected from, which enable the locking clamping plates to stay fixed at the position they have been initially attached to.
Another aim of the invention is to provide a clamping plate having bone cement injectable screws through which bone cement can be injected from.

The clamping plate (1) to be used in humerus operations, having screws through which bone cement can be injected from, in order to ensure the fixation of the plate at the position has been placed on and which is used in order to fix the locking clamping plates that have been attached onto the humerus basically comprises,
at least a screw (2),
- at least a helical screw thread (3) located around the screw (2), which enables the movement of the screw (2) on the bone onto which it is attached to, when the screw (2) carries out a rotation movement in a certain direction, at least a channel (4) located in the centre of the screw (2) which is used to fix the bone, and through which the bone cement reaches the bone,
- at least a pointed tip (5) located at the end of the screw (2) that is to be attached to the bone, designed to have a smaller diameter than the diameter of
the screw (2) in order for the screw (2) to open space for said tip, thereby being enable to transfer to the bone the force applied to the end of the screw (2) that has not been attached to the bone, as high pressure,
at least a small channel (6) opened on the screw (2) preferably proximal to the bone in order to enable the injected bone cement to reach the bone,
at least a head (7) located on the screw (2) at the end of the screw (2) which has not been attached to the bone,
- at least a groove (8) located on the head (7) enabling the screw (2) to be rotated around itself by having a rotator inserted therein and thereby also enabling the screw (2) to move inside the bone.
According to a preferred application of the invention, the clamping plate (1) having screws through which bone cement can be injected from is formed of a screw (2). The helical screw thread (3) located around the screw (2) and which wraps around the screw, enables the movement of the screw (2) on the bone onto which it shall be attached to, when the screw (2) carries out a rotation movement in a certain direction. Moreover the movement amount of the clamping plate (1) having screws through which bone cement can be injected from can be measured by means of the spaces of the helical screw threads (3) and the desired amount of movement can also be obtained by adjusting the helical screw thread (3) spaces. The channel (4) located inside the screw (2) and preferably at the centre of the screw enables the injected bone cement to move through the screw (2). Besides this, the geometry of the channel (4) may be according to the shape of the clamping plate (1) having a bone cement injectable screw, and therefore it enables the bone cement to reach each bone it has been attached to. A pointed tip (5) is provided on the screw (2) having a diameter smaller than the screw (2) diameter, in accordance with the geometry of the screw (2). By means of this pointed tip (5), the screw (2) can open a path for itself on the bone. Moreover the pointed tip (5) can transfer the force applied onto the screw (2) due to its diameter at the highest possible pressure and it enables the clamping plate (1) having screws through which bone cement can be injected from to be attached into the bone.
The small channels (6) that are again provided on the screw (2) which can be attached to the desired screw (2) region, positioned preferably vertically into the channel (4) located thereon, enable the bone cement that has been injected into the screw (2) to be transferred to the bone and therefore fixes the screw (2) inside the bone. Additionally, the small channels (6) also enable the bone cement to reach the bone at the desired intervals. Moreover the bone cement injected by means of the screw (2) again fills into the small channels (6) located again on the screw (2) and the small channels (6) expand when said cement dries. By means of this expansion the clamping plate having screws through which bone cement can be injected from fits precisely into the bone and its chance of movement in the bone is reduced. A head (7) located on the screw (2) at the end of the screw (2) which has not been attached to the bone has been provided. A groove (8) is located on the head (7) in order to ensure the attachment of the apparatus to screw (2) and to provide the movement of the screw (7). By means of this groove (8) the desired apparatus can be attached to the screw (2) and the movement of the bone inside the screw (2) is enabled at the desired precision and amount.
According to a another application of the invention, the screw (2) provided on the clamping plate (1) having screws through which bone cement can be injected from is positioned such that the pointed tip (5) is at the forefront when it is inserted into the hole opened in the bone.
According to a another application of the invention, bone cement exits out of the small channels (6) provided on the clamping plate (1) having screws through which bone cement can be injected from and the cement completely fills the surrounding area of the opened small channels (6).
According to a another application of the invention, by means of the screw (2) provided on the clamping plate (1) having screws through which bone cement can be injected from, the bone cement stays in the form it has been positioned at, by means of the clamping plate (1) having screws through which bone cement can be
injected from, and any kind of discharge of the cement is prevented. The bone cement exits out of the small channels (6) and contacts the bone and therefore enables the precise fixation of the clamping plate (1) having screws through which bone cement can be injected from.
According to a another application of the invention, by means of the discharging of the bone cement from the small channels (6) which moves through the channel (4) provided on the clamping plate (1) having screws through which bone cement can be injected from, the clamping plate (1) having screws through which bone cement can be injected from is precisely fixed and its displacement from its position is completely prevented.
