Description
Technical Field
The utility model relates to an old fracture treatment field specifically is a cheekbone old fracture is with cutting bone baffle and coaptation board.
Background
At present, the economic and social development of China is steadily accelerated in a special period. With the great popularization of vehicles and the obvious acceleration of the rhythm of life of people, traffic accident injuries are increased year by year, and jaw face trauma and jaw bone fracture, particularly complex jaw face trauma, are gradually increased. It has the characteristics of serious illness, complicated injury condition, frequent and multiple injuries, and the like, which all lead to the increase of the incidence rate of old fracture. Some areas are limited by socio-economic development and medical level, and many patients have difficulty in obtaining good stage I treatment, which also results in an increase in cases of bone deformity after trauma surgery.
The cheekbones are protruded at the maxillofacial position and are easy to be impacted to cause fracture, and the fracture incidence rate is always positioned at the front row of the maxillofacial fracture. Because the wound is closely related to the cranium, the eye sockets and the nasal cavity, when complex maxillofacial trauma occurs, the injured person often causes the injury of the cranium and the eye nose at the same time; in addition, the patients often suffer from injuries of other organs and limbs due to their large injurious energy. At this time, the treatment of maxillofacial fracture is often delayed for a long time, so that facial deformity or dysfunction of different degrees, including dysfunction such as serious malocclusion and diplopia, are caused, and great pain is brought to the body and mind of a patient.
The treatment of the patients has great difficulty, different from the early treatment of maxillofacial fracture, the old fracture of the zygomatic bone is difficult to achieve the functions and the forms after the early fracture, and the treatment difficulty of completely recovering the height, the width and the convexity of the face of the patients is always the treatment difficulty of the diseases.
The current common means comprise navigation operation, pre-bending titanium plate fixation, 3D printing guide plate and the like, and the treatment effect is improved to different degrees.
In such fractures, the fracture lines have healed to different degrees due to the over-long time of injury, and the fracture lines have disappeared or are filled with callus with different degrees of calcification, which makes it difficult for the operating surgeon to loosen the bone block during the separation process, and even for some patients, the bone block needs to be completely loosened by means of osteotomy. In the process of reduction, because the fracture line which is an important standard of reduction does not exist, an operator can often judge whether the fracture is reduced or not only by experience, but the reduction is often not accurate enough, and complications are easy to generate.
The most commonly adopted solution in clinic at present is the navigation surgery technology, which can effectively improve the surgery precision compared with the traditional surgery method. However, the operation is complex, the operation time is greatly prolonged, and meanwhile, the operation navigator has high price, hundreds of thousands of movement and is difficult to bear by small and medium-sized medical institutions. The other method is to pre-bend the titanium plate for fixation based on digital surgery to assist in positioning, but the accuracy is questionable due to the lack of uniqueness of the nail hole position.
