Problems solved by technology

[0048] 2. Lack of proper clamping: Due to the bicortical fixation / fastening method instead of single cortical fixation, the plate of the present invention provides an unrivaled secure clamping
[0049] 3. Difficulty with proper fixation in the pelvic region: This novel plate is an anatomically edge-specific plate that provides stability and fixes to the superior and medial surfaces of the pelvic rim

Embodiment Construction

[0136] The present invention relates to a novel acetabular compression plate with bicortical fixation and its fixation method for reconstruction of acetabular fractures even in osteoporotic bone. The plate is contoured according to the natural anatomical curves and shape of the pelvic bone rim so that it can be easily placed on the pelvic rim and thus properly positioned to give a secure grip. Therefore, it is called "anatomical board". When fixed to the bone, the new plate provides three times the strength of the bone compared to the actual bone strength, making it an excellent product for repairing acetabular fractures.

[0137] Anatomical features of the plate include a notched portion and a central portion that is anatomically shaped to correspond to the shape of the pelvic rim. notch part ( Figure 7 Part N) of the rim will fit into the pelvic rim at the rear of the rim so that the plate anatomically fits over the rim and does not slide back, thereby maintaining its corr...

Abstract

A plate having unique anatomical brim specific shape and enables dual cortical fixation i.e. fixation from outer cortical region and inner cortical region, in a quick and easy manner is disclosed. Dual cortical fixation using nut and bolt enables compression (grip), enabling repair of fractures in normal as well as osteoporotic bone. The plate rests on to brim of pelvic so that a single screw or more screws can be inserted into it from the outer cortex of the bone that comes out of the brim, as brim is the strongest portion and holds the screws well. The screws are held into the bone using bi-cortical fixation by means of cannulated screws which are provided with washers to increase surface area of contact with bone. Owing to ease of use, the plate drastically reduces surgery time from fewhours to less than an hour.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to medical devices for plastic surgery. More specifically, the present invention relates to a novel acetabular compression plate with bicortical fixation and its fixation method. The bone plate is suitable for reconstructing acetabular fractures, especially acetabular fractures with osteoporotic bone, and is made of suitable metals such as medical stainless steel and titanium. Background technique [0002] Fractures in the hip area (acetabulum) are often due to accidents, falls, etc., and are very difficult to repair. Existing methods involve the use of metal "plates" that need to be secured in the hip region with screws. [0003] Limitations of Existing Plates [0004] i. Loosening Over Time - The plate loosens over time because the fixation is from one side only. Over time, the set screws lose their clamping force, whereby the bone plate becomes loose. Existing bone plates do n...
