Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a guide with a loop titanium plate for treating distal clavicle fractures. Background Art

[0002] Distal clavicle fractures are common in young people, mostly caused by falling on the shoulder. Neer classification is often used to guide treatment in clinical practice. Neer classification is divided into three types according to the relationship between the fracture line and the coracoclavicular ligament. Among them, Neer IIb type is extremely unstable due to combined rupture of the conoid ligament. The probability of nonunion or delayed union of the fracture with conservative treatment is very high. Therefore, for this type of fracture, domestic and foreign scholars mostly advocate surgical treatment.

[0003] At present, there is only one acromioclavicular joint dislocation guide in clinical practice, which is suitable for the surgical treatment of acromioclavicular joint dislocation. It is performed under the guidance of an arthroscope and the surgical approach is also different. Currently, this type of guide cannot achieve surgical guidance for distal clavicle fractures.
