ABSTRACT:
An extractor for removing intramedullary fasteners such as Sampson rods and Rush rods from bone comprises a support including two spaced end plates connected by spreader rods, a carriage assembly having an engaging element adapted to engage one end of the intramedullary fastener and a threaded shaft connecting the support and carriage assembly and being adapted with the support to rotate and axially move the carriage assembly between the end sections of the support. The engaging element connects to the carriage assembly through a bearing element which prevents rotation of the engaging element, and in turn the intramedullary fastener, during the axial movement of the carriage assembly required to remove the fastener.
