Abstract
An intramedullary nail is provided for a closed reduction of a fracture of a tubular bone by insertion into a bore in the medullary cavity thereof. The intramedullary nail has a simple configuration, is practice-oriented, and can be used simply, quickly, safely and with only minimal use of intraoperative X-ray imaging, and without requiring interventions in undamaged areas of an extremity. The intramedullary nail has a nail core at a front area of which there is a head piece on which a start of a band is secured. The band is wound on around the nail core and, at its end in a rear area, is secured so that it can be locked in rotation around the nail core and which, in the event of a rotation counter to its direction of winding on, widens the radial contour of the intramedullary nail.
Claims22
An intramedullary nail for closed reduction of a fracture of a tubular bone by insertion into a bore in a medullary cavity of the tubular bone, the intramedullary nail comprising:
- a nail core having a front area and a rear area;
- a head piece disposed at said front area of said nail core;
- and
- a band having a starting end secured to said head piece, said band wound on around said nail core, said band having a rear end secured to said rear area of said nail core so that said rear end being locked in rotation around said nail core and said band, in an event of a rotation counter to a direction of winding on of said band, widens a radial contour of the intramedullary nail.
An intramedullary nail for closed reduction of a fracture of a tubular bone by insertion into a bore in a medullary cavity of the tubular bone, the intramedullary nail comprising:
- a nail core formed as a clamping and closing mechanism having an inner bushing and an outer bushing;
- and
- a single band wound in opposite directions starting from a tip, configured as a head piece, said single band having inner windings forming an inner band and outer windings forming an outer band, said inner band secured to said inner bushing and said outer band secured to said outer bushing, and in an event of a rotation counter to a direction of winding on of said outer band, said single band widens a radial contour of the intramedullary nail.
