RadioStereometric Analysis (RSA®) (Prod 3661)
About RadioStereometric Analysis (RSA®) (Prod 3661)
RSA® was originally designed for research and is applicable when you are interested in accurate measurements of skeletal or implant movements, and especially when it is considered to be of interest to measure these movements in three dimensions.
Migration of hip arthoplasties or of other artificial joints exceeding 0.050 - 2 mm can be detected by RSA.
To obtain skeletal markers, spherical markers made of tantalum are installed (0.5, 0.8,1.0 mm).
The material is biocompatible, i.e. it is well tolerated by the body and is readily observed as a distinct point in the radiograph.
The UmRSA injector is used for insertion of tantalum markers during surgery.
The markers are inserted into the anatomic structure in question, usually the skeleton.
