HipGrid is offered in two sizes and designed to attach to any 9 or 12 inch C-arm image intensifier. Once in place and covered by a sterile drape, the surgeon positions the grid pattern over the appropriate anatomical landmarks.
HipGrid reveals fluoroscopic distortion inherent in C-arm images allowing the surgeon to make informed decisions when restoring patient leg length and hip offset while helping to achieve optimal acetabular cup positioning.
A typical C-arm image of the pelvis shows what appears to be a highly precise view of the anatomy. However, fluoroscopic distortion is revealed using the HipGrid technology. The distortion, if not recognized and addressed, could lead to suboptimal intra-operative decision making. HipGrid empowers surgeons to more fully evaluate component positioning and anatomical alignment intra-operatively, aiding in the determination of:
