Proximal Ulnar Osteotomy Orthopedic Guide System

Abstract

The invention relates to a guide board system for an orthopaedic surgery of osteotomy of an ulnar near segment. The system comprises an osteotomy guide board and a shaping guide board. The osteotomy guide board is provided with an osteotomy guide board body and an osteotomy electric saw groove. The shaping guide board is equipped with a distal-end shaping guide board, a near-end shaping guide board and a universal rotary extending button connecting the distal-end shaping guide board with the near-end shaping guide board. The osteotomy guide board body, the distal-end shaping guide board and the near-end shaping guide board are completely attached to the back side of an ulna ruler. Due to the guide board system for the orthopaedic surgery of osteotomy of the ulnar near segment, precision ofosteotomy and shaping is improved. The operation difficulty is lowered. Firm fixation is achieved. The success rate of an old Monteggia fracture surgery is greatly increased. The recurrence rate is lowered. The elongation technology of corrective osteotomy of the ulna of old Monteggia fracture is enhanced. The clinical effect of the old Monteggia fracture surgery is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a guide plate system for proximal ulna osteotomy orthopedic surgery. Background technique [0002] Old Monteggia fractures refer to fractures of the superior 1 / 3 of the ulna combined with anterior dislocation of the radial head. They are more common in trauma, and the injuries are more complicated, so it is easy to miss diagnosis. Radial head dislocation can lead to limb dysplasia, shortened limbs, limited elbow flexion, cubitus valgus deformity, and even serious adverse consequences such as osteoarthritis and delayed radial nerve deep branch injury. Conservative treatment was ineffective, and surgical treatment was used. We should take a positive attitude towards old Monteggia fractures and take surgical treatment as soon as possible, which will help restore the normal anatomical relationship of the injured limb. [0003] The basic steps of old Monteggia fracture s...

Problems solved by technology

Clinically, flexible methods such as bending steel plates are used to perform surgery. This method has the following defects: 1. The angle of steel plate shaping and the distance of extension are mainly based on experience, and there is no reliable data guidance; The angle and length cannot be adjusted in a timely manner, resulting in unsatisfactory results; 3. Errors such as displacement or loosening are prone to occur during the plate fixation process; 4. The operation time is long, resulting in a lot of bleeding for the patient

All of the above reduce the success rate of old Monteggia fracture surgery, resulting in a higher recurrence rate

[0004] In summary, there is an urgent need for a medical device or device that can reduce the difficulty of osteotomy, shaping and fixation steps, improve the accuracy of osteotomy, shaping and fixation, and improve the clinical effect of old Monteggia fracture surgery. method, but there is no related report
