DESCRIPTION AN EXTERNAL FIXATOR WITH ALIGNMENT APPARATUS Technical Area This invention is used for the treatment of bone fractures in surgical operations. internal bone bonding with tooth fixation during treatment on bone and an alignment device that allows the alignment to be used together. relates to the external fixator. Prior Art Bones, the ability to hold on to surrounding tissues that support body movements are hard and solid structures. In skeletal structure, the length is more than the thickness bones are classified as long bones. Longest in human skeletal structure bone is the femur (thigh) bone. From the original form of the bone, impact, pressure and and sometimes osteoporosis, bone tumors and “oteogenesis” due to trauma. bone fragmentation into multiple parts due to diseases such as “imperfecta” It is called kirigi. For the treatment of the fracture, depending on the structure of the fracture, it is closed. reduction, cast, external fixation, open reduction, plate screw fixation or One of the intramedullary nailing methods is used. femur bone, It is one of the strongest and largest bones in the body. femur bone, hip It starts from the knee joint and extends to the knee joint. In femoral bone fractures generally using indirect reduction techniques and not disturbing the blood supply For this purpose, healing is achieved by applying fixation without opening the fracture line.

Intramedullary nails, miscellaneous plaques, and fractures of long bones such as femur implants such as external fixators are used. such as femur, humerus, tibia Intramedullary nail method is usually the first choice in long bone fractures. is used. On the other hand, in order to prevent the bone from misalignment, The external fixation method can also be used.

In current applications, external fixation method in long bone fractures is also used. is used frequently. External fixators in wound care in open fractures It provides convenience, but it can cause nail infection and limitation of movement in the knee joint. is among the important disadvantages of the external fixator. external fixation is a method of bone fixation outside the body. Fixator, external to the body It is attached to the bone with nails or wires. These nails attach the external fixator to the bone. They pass through the skin and sometimes through the muscles to bind. two or more nails It is placed to hold the broken bone in place and attach it to the fixator. external fixation treatment method is also used in bone infections, nonunion and wrong It is used in fusion fractures and bone extensions. external fixation The biggest problem encountered in the method is the fracture of the bone other than the bone. It is the difficulty of bone and hole fixation on the bone during fixation.

Therefore, using methods such as laser, navigation system, ultrasound. bone and hole detection is done. In this case, the operation time is prolonged and Complications may occur during the operation with these methods.
