Sammanfattning
In 1974 Selvik introduced marker-based roentgenographic stereogrammetric analysis (RSA), a highly accurate technique for measuring three-dimensional migration of orthopaedic implants. Novel, promising, user-friendly, fast and in some cases noninvasive RSA techniques (model-based RSA, image-based RSA and fluoroscopic RSA) have been developed, and some have recently been validated. However, the most reliable RSA technique so far is marker-based RSA. A standardization protocol for RSA studies is required. In the future, implant-testing using RSA should be used routinely in selected Danish orthopaedic units.
