ARRCH ORTHOPAEDICS’ Total Elbow Arthroplasty System
Admin
Unhinged - Unabridged! #NeoArmory:
Conquering longevity in Total Elbow Arthroplasty still seems out of reach and innovation seems to have reached a plateau. Hinge wear, stem pull-out, stress shielding, etc., keep making a mark in the ODEP rating.
Trying to solve all problems at once is ARRCH ORTHOPAEDICS’s style. Stem pullout? Intramedullary screw-in prosthesis with cross-locking screws may be the answer. Hinge wear? Let’s make is semi-constrained. Snap fit like Ikea. Tired of stress shielding? Reonstructed ligaments keep the bone occupied.
One of their proprietary techs includes the ‘Cylindrical Ligament Retention Device’ (also an excellent photographer) which fits into the prosthesis for mediolateral stability. Oh also, has your Hinge worn out? Just go in and replace the poly. Just like minor service for your car.
Please mind, that all these are theorized and extensively tested mechanically - yet to see any clinical studies and follow-up studies. Just have a look at their website. Extensive research and reasoning for everything from spool nuts to washer design.
After reading through their op-tech - only to realize there are another 3 PDFs to go through
