The old Monte fracture refers to 1/3 fracture on the ulna with anterior dislocation of the radius head, which is often seen in trauma, complicated in injury and easy to miss diagnosis. Dislocation of the head of the radius can cause poor limb development, limb shortening, limited elbow joint flexion, and even serious adverse consequences such as osteoarthritis, delayed radial nerve deep branch injury and the like in elbow eversion deformity. The conservative treatment effect is poor, and the operation treatment is adopted. The old Monte fracture should be kept in positive attitude, and the operation treatment is adopted as early as possible, thus being beneficial to recovering the normal anatomical relationship of the injured limb.
The basic steps of the old Monte fracture operation include incision and exposure, reconstruction of the annular ligament, reduction and fixation of the radius and the ulna. Extension of ulna osteotomy angulation is the key to the treatment of old Meng's fracture to correct deformity after ulna fracture. At present, the operation is performed by using a flexible method such as bending a steel plate, and the method has the following defects: 1. the shaping angle and the extending distance of the steel plate are mainly based on experience, and reliable data guidance is not provided; 2. the angle and the length of the steel plate can not be adjusted in time in the actual operation process, so that the effect is not ideal; 3. errors such as displacement or looseness easily occur in the process of fixing the steel plate; 4. the operation time is long, and the bleeding volume of the patient is large. The success rate of the old Mongolian fracture operation is reduced, and the recurrence rate is high.
In view of the above, there is a need for a medical device or method that can reduce the difficulty of the osteotomy, shaping and fixing steps, improve the precision of osteotomy and shaping and the firmness of fixing, and improve the clinical effect of old meng fracture surgery, but no relevant report is found at present.
