Abstract
An arthrodesis nail and nail adapter system having multiple coupling positions includes a bent arthrodesis nail and a nail adapter. The nail has multiple evenly spaced notches. The nail adapter has multiple evenly spaced protrusions corresponding to the notches. An arthrodesis nail adapter and target arm system having multiple coupling positions includes a nail adapter and a target arm. The nail adapter has a predetermined coupling orientation with a bent arthrodesis nail. The target arm has multiple coupling positions with the nail adapter. The arthrodesis nail and nail adapter system allows rotation of the bent nail for reduction of ankle deformity.
Claims10
An arthrodesis nail and nail adapter system having a plurality of coupling positions, comprising:
- a unitary bent arthrodesis nail having a longitudinal axis of rotation, a first end orthogonal thereto with a plurality of evenly spaced notches, and a second end extending from a bend therein at a fixed angle;
- and
- a nail adapter having a plurality of evenly spaced protrusions extending longitudinally from a first nail adapter end corresponding mateably to the plurality of evenly spaced notches throughout the plurality of coupling positions;
- wherein the plurality of coupling positions are positions of the nail adapter relative to the unitary bent arthrodesis nail;
- and wherein the nail adapter is operative to remain in an original position when the unitary bent arthrodesis nail is rotated around its longitudinal axis.
An arthrodesis nail adapter and target arm system, comprising:
- a unitary bent arthrodesis nail extending along a longitudinal axis from a first end to a fixed angle bend and from the fixed angle bend to a second end;
- a nail adapter mated to the first end of the unitary bent arthrodesis nail;
- and
- a target arm having a plurality of coupling positions with the nail adapter;
- wherein the nail adapter is operative to keep the target arm in an initial position relative to a subject's ankle when the unitary bent arthrodesis nail is rotated around its longitudinal axis within the subject's ankle.
