This invention relates to the detection and quantification of D-dimer levels in a sample derived from a patient having or suspected of having periprosthetic joint infection (PJI) and subsequent diagnosis of PJI.

Methods utilizing D-dimer for diagnosis of periprosthetic joint infection

Methods and systems for selecting an appropriate prosthesis for a prospective implant recipient are discussed. For example, a method for selecting an appropriate prosthesis can include, accessing anatomical image data, receiving an indication of a plurality of landmark locations within the image data, constructing a femoral canal axial indication within the image data, producing a plurality of lateral anatomic structural measurements, and selecting the appropriate prosthesis to fit the prospective implant recipient. The anatomical image data can include sufficient detail to allow measurement of internal and external geometry of a proximal femur. The plurality of lateral anatomic structural measurements can include measurements along, and perpendicular to, the femoral canal axial indication that run along a femoral canal within the anatomical image data. The prosthesis can be selected based, at least in part, on the plurality of lateral anatomic structural measurements.
