Abstract
The present invention is about an intra-corporal telescopic osteo-distraction device for locking the length of the bone and for providing axial, torsional and bending stability; an extra-corporal force producing device for producing a force for extension causing a lengthening of the intra-corporal device and the bone; a method for bone lengthening and a bone lengthening arrangement utilizing the devices of the invention.
Claims6
A method for stabilizing bone comprising:
- providing an intra-corporal telescopic osteodistraction device, including two fixing points for attachment with locking screws to a bone in a way that enables increasing the distance between the locking screws in a controlled manner, wherein the device is configured to provide unidirectional movement in the direction increasing a distance between the fixing points and preventing movement in the return direction and preventing twisting of the device and the bone, wherein the osteodistraction device is arranged to lengthen with the lengthening unidirectional movement of the bone, and configured to indicate the amount of lengthening;
- and
- providing an extra-corporal device configured to produce a force for extension causing the lengthening of the intra-corporal device and the bone;
- positioning the extra-corporal device on the bone, wherein the extra-corporal device is adapted to be attached to outer features of the bone and includes at least two screws and configured to be manually adjusted to lengthen the extra-corporal device.
1 more element
A method for lengthening bone, comprising:
- providing an extendable intra-corporal device configured to extend the bone and locking the length of the bone and configured to provide axial, torsional and bending stability;
- and
- providing an extra-corporal device configured to produce a force for extension causing a lengthening of the intra-corporal device and the bone;
- detecting and transmitting information about the lengthening of the intra-corporal device;
- and
- receiving the information about the lengthening and for controlling the extension in the extra-corporal device, wherein the extra-corporal device is adapted to be attached to outer features of the bone and includes at least two screws and is configured to be manually adjusted to lengthen the extra-corporal device.
