Method and apparatus for orthopedic fixation
View Patent ↗The present teachings provide one or more surgical instruments for repairing damaged tissue, such as in the case of a hip or femoral fracture. The present teachings can also provide one or more orthopedic screws that can be inserted in and/or removed from bone using any of a dedicated driver or any of commonly available drivers. The present teachings can further provide a surgical instrument that includes dual reconstructive wires and associated method, among other instruments and methods for repairing a hip or femoral fracture.
1. A dual reconstructive wire system for use with an anatomy comprising:
a first guide wire having a first end, a second end and defining a first length, the first end of the first guide wire operable to engage the anatomy, and the second end extending outside the anatomy at a first distance;
a second guide wire having a first end, a second end and defining a second length, the first end of the second guide wire operable to engage the anatomy, and the second end extending outside the anatomy at a second distance, wherein the first guide wire has a colored coating to visually distinguish the first guide wire from the second guide wire, wherein the first end of the first guide wire and the first end of the second guide wire each include a bone engagement feature to facilitate the engagement of the first guide wire and the second guide wire with the anatomy; and
wherein the second distance is greater than the first distance and the second length is greater than the first length to enable the second guide wire to be coupled to the anatomy after the first guide wire is coupled to the anatomy such that an instrument used to couple the second guide wire to the anatomy does not contact the first guide wire;
a first guide instrument adapted to be coupled to the anatomy, the first guide instrument including a guide that defines at least a first aperture and a second aperture;
a first cannulated insertion instrument that has a first end operable to be inserted into the anatomy, and a second end that extends beyond the anatomy, with at least a portion of the first cannulated instrument received through one of the first aperture or the second aperture;
a second cannulated insertion instrument that has a first end operable to be inserted into the anatomy, and a second end that extends beyond the anatomy, with at least a portion of the second cannulated instrument received through the other of the first aperture or the second aperture; and
wherein the first guide wire passes through the first cannulated insertion instrument such that the first end and the second end of the first guide wire extend beyond the first end and the second end, respectively, of the first cannulated insertion instrument, and the second guide wire passes through the second cannulated insertion instrument such that the first end and the second end of the second guide wire extend beyond the first end and the second end, respectively, of the second cannulated insertion instrument.
2. The system of claim 1 , wherein the first guide instrument is substantially L-shaped and is configured to engage an antegrade intramedullary nail.
3. The system of claim 1 , wherein the first guide instrument is substantially U-shaped and is configured to engage a retrograde intramedullary nail.
4. The system of claim 1 , wherein the first cannulated insertion instrument and the second cannulated insertion instrument each include a trocar and at least two soft tissue sleeves, at least one of the at least two soft tissue sleeves having a stop that contacts the first guide instrument, the trocar operable to penetrate a soft tissue of the anatomy, with a first one of the at least two soft tissue sleeves slideable over the trocar and having a diameter larger than the trocar to create a passageway through the anatomy, and a second one of the at least two soft tissue sleeves having a second diameter larger than the diameter of the first one of the at least two soft tissue sleeves, the second one of the at least two soft tissue sleeves slideable over the first one of the at least two soft tissue sleeves to increase the diameter of the passageway formed by the first one of the at least two soft tissue sleeves in the anatomy.
5. The system of claim 4 , wherein the passageway formed by the first one of the at least two soft tissue sleeves through the soft tissue terminates adjacent to boney tissue in the anatomy.
6. The system of claim 1 , further comprising:
a gage that includes a first scale, a second scale, and defines a single bore, that receives the second end of the first guide wire, which extends beyond the first cannulated insertion instrument to measure a depth of the first guide wire within the anatomy with the first scale, and receives the second end of the second guide wire, which extends beyond the second cannulated insertion instrument to measure a depth of the second guide wire within the anatomy with the second scale.
7. The system of claim 6 , wherein the first scale has a color that corresponds to the colored coating of the first guide wire.
8. The system of claim 1 , further comprising:
a second guide instrument that includes a post that couples the second guide instrument to one of the first aperture or the second aperture and defines a slot for receipt of at least one of the first guide wire and the second guide wire to verify the alignment of the first guide instrument with the anatomy.
9. The system of claim 4 , wherein the first cannulated insertion instrument and the second cannulated insertion instrument each include a stop that mates with the first guide instrument to limit the advancement of the first cannulated instrument and second cannulated instrument through the first aperture and second aperture.
