Problems solved by technology

[0003] Currently, commercially available test products do not adequately meet clinical needs or economic concerns
Anatomical metal trial articles are heavy, can be expensive to manufacture, and do not adequately allow visualization of screw locations using imaging techniques
Anatomical plastic trial articles, while lighter weight and more cost-effective, are often considered less durable and do not adequately allow visualization of screw locations using imaging techniques
Furthermore, two-dimensional profile metal or plastic trial articles are easier and cost-effective to fabricate but do not provide the anatomical information required by the surgeon and do not adequately allow visualization of screw locations using imaging equipment

Embodiment Construction

[0042] The subject matter will be described more fully hereinafter with reference to the drawings and examples showing representative embodiments. However, the subject matter may be implemented in different ways and should not be construed as limited to the embodiments or examples shown herein.

[0043] The present invention discloses a novel composite test article consisting of at least both a metal wire frame and a polymer substrate. It has been found that the composite trial implant to be described (also referred to herein simply as the "trial") provides improved performance of the trial for use during orthopedic trauma surgery. Trials according to the invention are able to better convey anatomical matching information, provide length and screw location, are more cost-effective than using actual sterilized implants, allow improved radiographic visualization and higher reliability.

[0044] In an exemplary embodiment, the present invention includes at least a wireframe. l...

Abstract

Disclosed is a system for trialing implants used in orthopedic surgery. The invention is directed to a composite trial implant that employs a polymer substrate having a size and shape to approximate abone plate, and radio-opaque indicia disposed thereon. The trial implant allows a surgeon to determine the correct size, hole configuration, and cross-sectional profile with a simulated device, thatpermits more rapid and accurate selection of a permanent implant.

Description

technical field [0001] In preferred embodiments, the present invention generally relates to systems and methods for implant trials in orthopedic surgery. Background technique [0002] During orthopedic surgery, various implants, plates and screws are commonly used to repair fractures and bone deformities. As is common in orthopedic surgery, the surgeon selects the plate size using the multiple implants available in the resterilized set to determine the correct length and in some cases width of the plate or implant required or depth. These implants are placed and moved over the surgical site, such as a fracture or bone deformity. However, current methods have disadvantages in that the re-sterilized implant devices may not include the required plates or implants, or such plates or implants are not located in screw holes, pilot holes (i.e., K-wire correct size or configuration of holes), etc. Additionally, when the plates are provided to the surgeon in sterile packaging, th...
