Background
Ulnar coronary processes are important anatomical structures that maintain stability of the elbow joint, and coronary fractures typically occur in the case of complex elbow joint fractures and dislocation, mainly due to axial loading during extension and varus or valgus rotation. To avoid recurrent instability or dislocation of the elbow, repair surgery is usually required, but the coronary fracture mass is often small and crushed, the surrounding anatomy is complex, and even for experienced clinicians, fixation remains a great challenge, and if the fracture fixation fails, it may lead to complications such as instability of the elbow joint, arthritis and stiffness. Concerns about the exact degree and firmness of coronary fracture repair often prevent a clinical clinician from starting early rehabilitation training after elbow fracture dislocation operation, so that the postoperative function training of a patient is not timely, and complications such as joint movement stiffness, ossificatory myositis and the like are easy to occur. The development, design and use of such fixation systems specific for coronary processes is therefore critical for prognosis.
In fact, the best fixation method for the coronal fracture is controversial. The steel plate is a common medical apparatus in fracture treatment, and at present, a special steel plate for coronary process fracture is not more, for example, liu Guan et al propose an ulna coronary process anterior medial horn steel plate (publication number CN 204683750), and the steel plate comprises a straight plate-shaped plate body, wherein the straight plate-shaped plate body extends to two sides to form a first support plate and a second support plate respectively, the structure of the straight plate body is matched with the anatomical form of an ulna coronary process anterior medial column, and locking pressurizing holes are formed in the plate, so that the fixation stability is improved.
