Problems solved by technology

These steel plates in the prior art are all designed for specific fracture types, and a set of steel plates cannot meet the needs of multiple fracture types at the same time, which increases the complexity of surgical instrument selection; It is difficult to bend and shape, and it is not easy to adhere to the bone surface. It not only has limited support for the fracture area, but also easily causes postoperative complications.

Abstract

The invention provides a combined fixing steel plate for acetabular fractures. The combined fixing steel plate comprises a bowed-edge main plate and an auxiliary plate, wherein the bowed-edge main plate is an arc-shaped strip-like steel plate and is bent to match with an anatomical structure on the inner side or upper portion of a bowed edge, the auxiliary plate is a strip-like steel plate and is selected from at least one of a posterior column ilium sitting steel plate, a square zone baffle, a middle column pubis sitting steel plate, a front wall steel plate and a rami superior ossis pubis steel plate. The fixing steel plate can better meet the treatment demands of various acetabular fractures, can be used for a variety of acetabulum reattachment surgeries different in approaches and can be used for a variety of acetabular fracture surgeries adopting different anterior approaches.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to a combined fixed steel plate for acetabular fractures. Background technique [0002] With the rapid development of the transportation industry, the number of patients with pelvic and acetabular fractures is increasing year by year. Due to the dense structure of important blood vessels and nerves around the pelvic acetabulum, it is very difficult to expose, and there are few safe areas around the acetabular bone. , all make the anatomical reduction of acetabular fractures extremely difficult. Therefore, the operation of pelvic and acetabular fractures has always been one of the most challenging and difficult operations in trauma orthopedics, and internal fixators for pelvic and acetabular fractures are emerging in an endless stream. [0003] Posterior column screws and “second window” screws are the most commonly used internal fixation for acetabular fractures. However, ...
