INTRAMEDULLARY DEVICES AND METHODS OF DEPLOYING THE SAME

摘要

Internally locking intramedullary nails/devices and methods of deploying internally locking intramedullary nails are disclosed. The nail includes a cannulated sleeve, a plurality of anchoring elements, and one or more extension mechanisms for outwardly extending anchoring elements to anchor against movement along an elongated axis of the sleeve. A first extension mechanism operative to outwardly extend at least one anchoring element of a first set of anchoring elements through respective radial openings in the sleeve at an oblique position facing one end of the sleeve to anchor against movement in a longitudinal direction and a second extension mechanism independent of/decoupled from the extension mechanism operative to outwardly extend at least one anchoring element of a second set of anchoring elements through respective radial opening in the sleeve at an oblique position facing the opposite end of the sleeve to anchor against movement in the opposite longitudinal direction.
