INTRAMEDULLARY FIXATION DEVICE FOR FRACTURES

摘要

An intramedullary fixation device for fractures is disclosed. The intramedullary fixation device has a core guide wire, and distal and proximal petal segments mountable on the core guide wire and being able to be moved towards each other. Each petal segment has multiple petals able to be expanded for gripping an internal wall of a medullary canal; expansion segments are also mountable on the core guide wire, each expansion segment having a tapered engagement surface for engaging with and expanding the petals of the distal and proximal petal segments. A corresponding method is also disclosed.
