Patient-specific mechanical navigation system addresses hip replacement problems (Helio)
press release --> HipSextant™ Navigation System Receives Its First Commercial Use
More than half of acetabular components placed are malpositioned, according to a recent study from Massachusetts General Hospital.
Component malposition is associated with the most common reasons for revision surgery including instability, wear and wear-associated loosening, and impingement.
The HipSextant Navigation System (Surgical Planning Associates Inc., Boston) is a mechanical instrument, adjusted on a patient-specific basis, designed to achieve appropriate component alignment. The method was invented and developed by Stephen B. Murphy, MD, of Boston.
Figure 1. The patient-specific 3-D plan for cup alignment using the mechanical navigation instrument is shown. The desired cup orientation is designated by the surgeon. The application calculates the instrument adjustments, such that, when the instrument is docked on the patient, the indicator points in the direction of desired cup orientation.
