Description

DESCRIPTION THE GRAFT TAKEN FROM THE HUMERUS BONE IS COMPLETELY AND COMPLETE TO THE GLENOID BONE GRAFT USED TO ENSURE COMPLETE COMPATIBILITY PREPARATION APPARATUS Technical Field The invention was made from a bone taken from the arm bone (hunerus bone) joint. shoulder bone (glenoid bone) where the graft is applied In order to ensure full and complete compatibility with the joint graft that can make cuts at different angles and thicknesses It is related to the preparation apparatus.

Known Status of the Technique There are two joints in the shoulder. The main shoulder joint consists of two bones OIUSUF. Arm bone (hunerus) and shoulder blade (scapula) is the main shoulder joint between the The joint is between the collarbone and the shoulder blade. and is called the acromioclavicular joint.

The cut ends of these joints are covered with cartilage. Shoulder round head of the arm bone (hunerus) that forms the joint surfaces the joint of the scapula called the glenoid. It is covered with articular cartilage throughout its wide range of motion. This The attachment is a ball-and-socket attachment. Big ball little nest The discrepancy between them is formed in the form of a ring called labrum. Stability is achieved by removing it with flexible cartilage.

Damage to the shoulder joint due to various reasons Therefore, hip prostheses can be used. Shoulder calcification, shoulder fractures, shoulder avascular Added problems due to necrosis and shoulder tumors Therefore, prostheses can be applied.

As in other prostheses, rootstocks are also used in shoulder prostheses. It is an imitation of the joint. With this rootstock, bone is attached to the prosthesis. It has a ball and socket form structure that can be connected must be kept.

The main idea in using prostheses is to replace the damaged joint. It is based on the idea of replacing surfaces with artificial surfaces.

In modern prostheses, the main structures are made of titanium materials that rub against each other. The surfaces are made of cobalt-chronolybdenum alloy and polyethylene. has been formed.

However, within different prosthesis applications, the structure of the joint Joints can also be imitated by differentiating their structure. For example; rotator nansetin is advanced and cannot be repaired ruptures, developing due to rotator nanset tear calcification, failed anatonic total shoulder prosthesis In cases where replacement is required and multi-piece upper arm Its components are in a structure that can be used in case of fractures. Therefore, the joint may need to be operated differently.

In these cases, the device is operated in reverse according to the anatomical joint. hip prostheses can be applied.

In the normal anatomy of the shoulder, there is a ball-shaped structure on the upper arm. the joint surface and the hollow socket section located in the shoulder blade A joint is formed with . Anatomical dentures It works by imitating normal anatomy. imitate anatomy The cavity and the ball in the upper arm in the total shoulder prosthesis Added with the clear bass in the form of artificial production It can be created.

In the Reverse Shoulder prosthesis, the netal presses the person in the form of a ball. while it is located on the shoulder blade, the socket-shaped person is placed on the upper arm. It is located in the bone. Opposite of normal anatonia Due to these structures, it is used as a reverse shoulder prosthesis. It is named.

In the reverse shin prosthesis, instead of the worn shin bearing, the ball and Again, a socket or bowl-shaped piece is placed at the end of the arm bone. The orientation of the shoulder joint can be changed by ligating The part that forms the bowl or nest is usually made of polymer. is a finished product. Made from polyethylene in many different applications Manufactured housing parts can be used. this type The housing parts, which can be made of polyner, slide the inserted It aims to imitate the movement.

Again, the OIUSIUFUIan head piece on the shoulder side is made of netal. It can be honored. The Nbtal piece is in ball form and Its movement inside the nest is ensured.

During the operation, due to the nature of the insertion, normally the ball ball-shaped bone end belonging to the arm bone It is cut into this part of the prosthesis piece in the form of a bowl. relatively flat area with placement It is being created.

Afterwards, a piece of the funeral root is suspended into the canicle, Depending on this root, the bowl piece is made flat. It is positioned on the joint surface.

It also forms the bowl extension of the shoulder bone. The section is also cut and flattened, and a net is applied to this section. The artificial joint element in ball form is connected.

For this connection, a circular base is attached to the netal ball. The part is fixed to the bone with screws.

Examples where the circular base part is also made of netal You belonged to the state of technology The textural harmony experienced today, especially in the thongs circular net to avoid problems from the seam at the part where the piece touches the shoulder seam. The graft parts taken can be used.

These graft pieces can be taken from the arm bone. It is already attached to the arm so that a bowl can be formed on it. Since the cannon section belonging to it was cut off and thrown away, this The graft to be taken from the section can be removed without harming the patient. You can easily collect With this rootstock, the ball, which usually belongs to the arm bone, is cut off. first from the bone ball, then to the incision of the shoulder seam and The circular base piece of the artificial attachment ball Graft can be taken depending on its structure.

The graft piece is usually taken from the center of the ball of the arm bone. It is cut out as a circular piece. This The piece can only be cut with existing incision devices at a fixed size and angle. and can be cut in shape.

The graft incision apparatus used with this rootstock is based on current technology. It is known within. This type of apparatus has previously been Allows cutting of graft of specified thickness and shape. is giving.

The graft taken in a fixed form using this type of apparatus, manually by the surgeon after the incision. thick enough to be compatible with the desired application area and It will need to be reshaped.

Reverse shin prostheses replace the natural components of the joint. It is operated in situations where it is heavily damaged. This In this case, the area where the application is made can be different surfaces. It can be cut in different ways to fit. This For this reason, the surface on which the graft will be placed on the shoulder side is In this case, you can have different structures for application. The surgeon selects the appropriate graft for this different surface structure. It should be applied by shaping.

It must be of different size and shape for each operation. Preparation of the graft with fixed cutting devices It will not be possible. These devices can only be used for constant thickness and in the form of a cylinder piece with a hole in the middle The lump belonging to the arm bone of the graft piece that can be It allows it to be taken.

Due to the variability of the surface formed at the application site. This cut graft is reassembled manually by the surgeon. It will need to be shaped.

The process of shaping the graft manually; both correct and appropriate It may cause the graft parts to be formed and It is a difficult and time-consuming incision for the surgeon to make. You may cause the action to be taken On the other hand, the shapes are made by hand. It is also important in terms of optimizing the shaping process. It can create problems. from a bone cutting apparatus used with the rootstock of the alignments It mentions. Described in the patent application The apparatus is compatible with incision apparatus known within the new technique. can be given as an example. The device in question is only Extraction of the graft in predetermined size and form It has a structure that allows it.

Using this apparatus, you can cut the graft to a fixed size and shape. The surgeon removes the graft and then grafts it manually. Again, the incision area must be prepared appropriately. It is mentioned in patent applications no.

However, in these structures, in the ordinary state of technology resizing of the graft encountered and It cannot provide a solution to the shaping problem.
