Clavicle repair device and orthopedic intramedullary fixation system
A bone segment positioning device including a base shaft, wherein the base shaft includes a base mating structure and an anchoring thread for securing the base shaft to a distal portion of a broken bone. Additionally, a collar shaft is provided, wherein the collar shaft includes a stabilizer base and a collar mating structure configured for associating with the base mating structure to secure the base shaft to the collar shaft. Moreover, a stabilizing device is provided, wherein the stabilizing device includes a collar configured for associating with the stabilizing base to secure the collar shaft with a proximal portion of the broken bone.
1. An intermedullary apparatus for providing compressive fixation of a bone comprising:
a base shaft having a base shaft proximal end and a base shaft distal end comprising an anchoring thread configured to secure said base shaft distal end to a distal portion of a broken bone from within an intermedullary canal of said broken bone;
a collar shaft having a collar shaft proximal end comprising a stabilizer base with a spherical outer surface and a collar shaft distal end configured to couple with said base shaft proximal end;
a collar configured to rotationally couple with said spherical outer surface of said stabilizer base, said collar comprising a cradle cavity configured to couple with an exterior surface of said broken bone; and
at least one sleeve positioned between said collar and said stabilizer base, said at least one sleeve configured to compressively couple said collar with said stabilizer base.
2. The intermedullary apparatus of claim 1 wherein said at least one sleeve comprises a circular retention sleeve positioned in said cradle cavity and a circular fastening sleeve positioned between said retention sleeve and said stabilizer base, wherein said retention sleeve comprises a sleeve lip configured to retain said collar, and wherein said fastening sleeve comprises a notch configured to couple with at least one key protrusion of said stabilizing base.
3. The intermedullary apparatus of claim 2 , wherein said fastening sleeve comprises an inner wall diameter, an outer wall diameter and a notch width, wherein said inner wall diameter, said outer wall diameter and said notch width are reduced when said fastening sleeve is compressed.
4. The device of claim 1 , wherein said collar is substantially oblong in shape, and wherein said collar includes a plurality of elongated sides and a plurality of shortened sides.
5. The device of claim 4 , wherein each elongated side includes a crescent shaped notch having a beveled notch edge, and each of said shortened sides is smoothly rounded.
