Patent Images
1. A fixation device for repairing a fracture of a bone having a medullary canal, the device comprising:
- a radial transcutaneous pin configured to be mounted generally radially to the bone on a first side of the fracture, the radial transcutaneous pin including an external free end;
an axial transcutaneous pin configured to enter the bone on a second side of the fracture and extend axially down the medullary canal, the axial transcutaneous pin including an external free end; and
an external member configured to extend between the free ends of the pins and secure them relative to each other, and where the axial and radial pins are non-intersecting and are adapted to be coupled to one another subcutaneously through their mutual engagement with the bone only.

8. A fixation device use in repairing a fracture of a patient'"'"'s bone, where the bone has a medullary canal, the device comprising:
-
a first intermedullary portion configured to extend longitudinally through a section of the medullary canal of the bone and span the fracture; an external member configured to be disposed external to the patient; a first transcutaneous portion configured to extend from the external member through the bone to the first intermedullary portion on a first side of the fracture; and a second transcutaneous portion configured to extend between and couple the external member and the bone on a second side of the fracture where the second transcutaneous portion and the first intermedullary portion are non-intersecting and the bone on the second side of the fracture can be manipulated relative to the bone on the first side of the fracture by moving the second transcutaneous portion relative to the first transcutaneous portion when the portions are engaged with the bone. - View Dependent Claims (9, 10, 11, 12, 13)
