Acetabulum posterior wall protection type bone fracture plate with elastic nail path and use method thereof

Abstract

The invention relates to an acetabulum posterior wall protection type bone fracture plate with an elastic nail path and a use method thereof, wherein the acetabulum posterior wall protection type bonefracture plate comprises a main body steel plate, an ilium plate body and an ischium plate body; the ilium plate body and the ischium plate body are located at two sides of the main body steel plate;the main body steel plate is similar to a bridge body structure and is arc-shaped; the whole structure has certain flexibility and plasticity; a slideway structure consistent with the long axis of amain body is arranged in the middle of the whole structure, the slideway structure is an oval hole, the direction of the long axis of the slideway structure is consistent with the trend of the main body steel plate, the side, opposite to an acetabulum edge, of the hole is '\'-shaped, the side, opposite to an acetabulum posterior column, of the hole is '('-shaped, and cortical bone screws, preferably 3.5 mm cortical bone screws, can be inserted into a formed slideway.

Description

technical field [0001] The invention discloses an acetabular posterior wall protective bone plate with an elastic screw channel and a method for using the same, belonging to the technical field of medical devices. Background technique [0002] Acetabular posterior wall fractures account for the highest proportion of all acetabular fractures, accounting for about a quarter. Because fractures of the posterior wall of the acetabulum involve the hip articular surface and are often combined with posterior dislocation of the femoral head, most of them require surgical treatment, requiring anatomical reduction of the articular surface and adequate internal fixation to obtain early functional training to avoid hip joint instability and trauma Arthritis formation. [0003] The posterior wall is a section of the circular acetabulum. When the plastic reconstruction plate or the existing anatomical plate is fixed on the inner side of the posterior wall, it is difficult to implant screw...

AI Technical Summary

Problems solved by technology

In the shaping process, not only the operation time is prolonged, but also the shape of the shaping is often quite different from the contour of the posterior wall of the acetabulum, and the tight attachment of the steel plate to the surface of the posterior wall of the acetabulum cannot be guaranteed. Lose the role of the protective plate, and it is easy to displace the reduced fracture again
