Total Hip Replacement is a highly successful surgery but there remains room for improvement.

Implants, materials, and techniques associated with the total hip replacement surgical procedure have advanced considerably over the past few decades.  But did you know that even the most experienced orthopedic surgeons generally do not know exactly what hip implant size or implant combinations will be required or even suitable until the surgery is well underway? 

It is important to recognize that most patients are highly satisfied with the results of their hip replacement surgery, and research has shown that most hip replacements last decades with few problems.  But these unsolved challenges are not fully addressed by “robotic” or “computer aided surgical navigation.”  Despite all of the technological advancements over the past few decades, a hip replacement surgery still requires the use of traditional and often antiquated medical imaging, x-ray, and intra-operative implant assembly guessing-and-testing!

The result: patients sometimes begin to recover from their hip replacement surgery and discovery that their leg with the hip replacement is either longer or shorter than the other.  Referred to as a “Leg Length Discrepancy,” unequal limb length is a very common reason patients report dissatisfaction after hip replacement.  This inequality can potentially cause lower back pain, limping, dislocation and early loosening of the hip replacement components.  There are several solutions available to correct a leg length discrepancy ranging from a simple but inconvenient shoe lift all the way to an additional revision surgery to correct the inequality.

OrthoGrid was founded on the basis of addressing the known challenges of leg length discrepancy.  Almost universally, orthopedic surgeons recognize that anatomical restoration is a top priority for every total hip replacement patient, and thankfully there are now novel and patented tools available to help physicians achieve the best possible outcome for each patient.

The Solution

Several improvements in recent years have demonstrated improved outcomes in total hip replacement.  New surgical techniques, such as the Direct Anterior Approach hip replacement, have accelerated patient recovery and enabled more robust return to activity.  The increased use of intra-operative fluoroscopy (x-ray) allows for improved surgeon visibility; however, until recently, no technical solution has existed to compensate for the natural imprecision and distortion occurring in fluoroscopic C-arm images.  However, today there are innovative, patented medical technologies developed by OrthoGrid Systems, that reveal fluoroscopic distortion for the physician during the procedure.  By revealing the distortion and providing a grid from which the physician can make more informed decisions, OrthoGrid’s HipGrid® and PhantomMSK™ Hip technologies enable the doctor to “see” the image differently and make appropriate adjustments during the procedure.  Many leading physicians across the United States rely on the HipGrid® or PhantomMSK™ Hip for enhanced decision making to achieve accurate leg length restoration.
