Anatomic artificial bone assisting reduction of proximal humeral fractures

Abstract

The invention relates to an anatomic artificial bone assisting reduction of proximal humeral fractures. The anatomic artificial bone comprises an lower fixator and an upper fixator; one end of the lower fixator is connected onto the upper fixator; the lower fixator is cylindrical shaped, and the axis of the lower fixator is coincided with the axis of the human humeral shaft during use of the lowerfixator; a humeral bone plane and cylindrical hollows corresponding to intertubercular sulcus are arranged on the upper fixator; the cylindrical hollows corresponding to the intertubercular sulcus are arranged on the side face of the upper fixator; a central locator is arranged on the humeral bone plane. The anatomic artificial bone has the advantages that reference marks can be provided for reduction of the proximal humeral fractures, rapid anatomical reduction can be highly assisted in terms of quantification, bone loss is filled, a supporting platform is provided for fractures, surgical process is simplified, and the anatomic artificial bone can serve as a novel medical instrument and has extensive application prospects in clinical use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anatomical artificial bone for assisting the reduction of proximal humerus fractures. Background technique [0002] Proximal humerus fractures account for about 4-5% of all fracture cases, among which the elderly account for a large proportion, and more than 71% of proximal humeral fractures occur in elderly people over 60 years old. With the arrival of an aging society, its incidence will gradually increase. [0003] For proximal humeral fractures with obvious displacement, conservative treatment often results in poor reduction effect, resulting in limited function of the shoulder joint. Therefore, surgery is the main treatment, including closed or open reduction, locking plate or intramedullary nail fixation, Artificial shoulder replacement etc. In order to preserve the original shoulder joint structure and shape, open reduction and locking plate and screw internal...

Problems solved by technology

However, regarding a technical scheme that provides a reference mark for the reduction of complex proximal humeral fractures, helps to restore the humeral head-shaft angle and retroversion angle, improves the accuracy of reduction, quickly anatomically reduces, fills bone loss, and supports the fracture fragments. no corresponding disclosure

[0009] To sum up, it is necessary to provide a reference mark for the reduction of complex proximal humerus fractures, which is helpful to restore the humeral head-neck-shaft angle and retroversion angle, improve the accuracy of reduction, fast anatomical reduction, and at the same time fill bone loss and support fracture fragments. Proximal humerus anatomical artificial bone, but there is no report about this artificial bone
