| Abstract: | A method for reducing and fixing fractures, for example, a proximal humeral fracture. A jacking device is releasably attached to a locking plate that presses against an inferior aspect of the head to rotate the head into anatomic alignment. Suture material is stitched into the soft tissue superior to the head and pulls the superior end of the head and guides and steers the head. The suture material is passed through suture holes in the superior end of the plate. The jacking device is positioned to hold the head in an anatomic neck/shaft angle, thereby allowing the head to be fixed to the locking plate. In one such embodiment, a swivel bushing in the plate receives the jacking device and allows the angle of the device to be adjusted as desired. To aid in the fluoroscopic visualization during surgery, a radiolucent retractor is used to avoid blocking the surgeon's view. |

| Claim: | 1. A method for reducing and fixing a fracture, said method comprising the steps of: a) position a distal portion of a plate against a bone shaft with a portion of said plate proximate the fracture and a proximal portion of said plate proximate a head; b) provisionally secure said distal portion of said plate to said bone shaft; c) reduce said fracture by rotating said head out of varus and into alignment with said shaft by performing the steps of c1) advancing an elongated member attached to said plate to push a first aspect of said head, and c2) pulling on suture material that is threaded through soft tissue attached to a second aspect of said head, said suture material threaded though openings in said proximal portion of said plate; and d) after said fracture is reduced, secure said proximal portion of said plate to said head and secure said distal portion of said plate to said bone shaft. |
| Claim: | 2. The method of claim 1 wherein step c) of reducing said fracture further includes a step of adjusting an insertion angle of said elongated member such that a proximal tip of said elongated member is positioned to contact a non-yielding surface of said head. |
| Claim: | 3. The method of claim 1 wherein step c) of reducing said fracture further includes a step of adjusting an insertion angle of said elongated member such that a proximal tip of said elongated member is positioned into an inferior aspect of said head. |
| Claim: | 4. The method of claim 1 wherein step c) of reducing said fracture further includes a step of attaching a jacking device to said plate, said jacking device including said elongated member. |
| Claim: | 5. The method of claim 1 wherein step c) of reducing said fracture further includes a step of manually manipulating with a retractor having a blade that is radiolucent. |
| Claim: | 6. The method of claim 1 wherein said step d) of securing said plate includes inserting a plurality of fasteners into corresponding openings in said plate, said plurality of fasteners attaching said plate to said bone shaft and said head. |
| Claim: | 7. The method of claim 1 further including, after said step d) of securing said plate, a step of removing said elongated member from said plate. |
| Claim: | 8. A method for reducing and fixing a fracture, said method comprising the steps of: a) position a plate against a shaft of bone wherein the fracture is located medially between a proximal portion and a distal portion of said plate, said plate being positioned with said distal portion proximate said shaft and with said proximal portion of said plate proximate a head; b) provisionally secure said distal portion of said plate to said shaft; c) reduce the fracture by performing the steps of c1) advancing a jacking device to push a first aspect of said head, and c2) pulling on suture material that is threaded through soft tissue attached to a second aspect of said head, said suture material threaded though openings in said proximal portion of said plate; and d) after said fracture is reduced, secure said proximal end of said plate to said head and secure said distal end of said plate to said bone shaft. |
| Claim: | 9. The method of claim 8 wherein said step c) of reducing the fracture includes rotating the head out of varus and into alignment with said shaft by pushing with said jacking device and pulling with said suture material whereby said head is rotated into alignment with said shaft. |
| Claim: | 10. The method of claim 8 further including, before said step c1) of advancing said jacking device, a step of adjusting an insertion angle of said jacking device such that a proximal tip of said jacking device is positioned to push against a non-yielding surface of said head. |
| Claim: | 11. The method of claim 8 wherein said step d) of securing said plate includes inserting a plurality of fasteners into corresponding openings in said plate, said plurality of fasteners attaching said plate to said bone shaft and to said head. |
| Claim: | 12. The method of claim 8 further including, after said step d) of securing said plate, a step of removing said jacking device from said plate. |
| Claim: | 13. A method for reducing and fixing a fracture, said method comprising the steps of: a) select a plate sized and configured to extend from a head to a shaft with the fracture positioned medially relative to said plate, said plate configured to receive a jacking device; b) provisionally secure a distal end of said plate to said shaft such that a proximal end of said plate is proximate the head; c) after said plate is provisionally secured, position a jacking device extending from said plate such that a proximal end of said jacking device is positioned to push against a first aspect of said head; d) after said plate is provisionally secured, thread suture material through soft tissue attached to a second aspect of said head and through a plurality of openings in said proximal end of said plate; e) after said jacking device is positioned and said suture material is threaded, reduce the fracture by rotating said head out of varus and into alignment with said shaft; and f) after the fracture is reduced, secure said proximal end of said plate to said head and secure said distal end of said plate to said shaft. |
| Claim: | 14. The method of claim 13 wherein step a) of selecting a plate includes a step of selecting said plate such that said jacking device extends from a proximal surface of said plate such that said proximal end of said jacking device is positionable to engage said first aspect of said head. |
| Claim: | 15. The method of claim 13 wherein step a) of selecting a plate includes a step of selecting said plate with said plurality of openings positioned proximate a peripheral edge of said proximal end of said plate and with said plurality of openings arranged in pairs and being sized and dimensioned to receive suture material. |
| Claim: | 16. The method of claim 13 wherein said step e) of reducing the fracture includes advancing said jacking device to push said first aspect of said head and by pulling said suture material to move said second aspect of said head toward said proximal end of said plate, thereby causing said head to rotate out of varus and into alignment with said shaft. |
| Claim: | 17. The method of claim 13 wherein step e) of reducing said fracture further includes a step of adjusting an insertion angle of said jacking device such that said proximal end of said jacking device is positioned to push against a non-yielding surface of said head. |
| Claim: | 18. The method of claim 13 wherein step e) of reducing said fracture further includes a step of manually manipulating with a retractor having a blade that is radiolucent. |
| Claim: | 19. The method of claim 13 wherein said step f) of securing said plate includes inserting a plurality of fasteners into corresponding openings in said plate, said plurality of fasteners attaching said plate to said bone shaft and said head. |
| Claim: | 20. The method of claim 13 further including, after said step f) of securing said plate, a step of removing said jacking device from said plate. |
