CRPP stands for Closed Reduction and Percutaneous Pinning, which is a medical procedure used to treat fractures. There are several synonyms for CRPP that are commonly used, including internal fixation, closed reduction and screw fixation, closed reduction and K-wire fixation, and closed reduction and intramedullary nailing. These procedures involve similar techniques and principles, with the aim of stabilizing and immobilizing the bone to promote healing. Each procedure has its own advantages and disadvantages, and the choice of technique depends on the location, type, and severity of the fracture. All in all, CRPP and its synonyms are important treatments to get patients back on the road to recovery after a fracture.
