Fracture fixation system including locking cap and wire
A locking cap for a fracture fixation system may include a cap body that extends along a longitudinal axis between a proximal end and a distal end. An external thread extends around at least a portion of the cap body. A passage extends inside the cap body from the distal end toward the proximal end. An internal thread extends about a periphery of the passage along at least a portion of a length of the passage.
1. A fracture fixation system, comprising:
a bone plate having a plurality of threaded openings;
a locking cap threadably secured within one of the plurality of threaded openings; and
a wire threadably attached to the locking cap,
wherein the locking cap includes a passage having an internal thread and a non-threaded portion proximal of the internal thread.
2. The system as recited in claim 1 , wherein the wire includes a threaded portion located distally and a non-threaded portion located proximally.
3. The system as recited in claim 2 , wherein the threaded portion extends to a trocar tip.
4. The system as recited in claim 3 , wherein the trocar tip is pointed.
5. The system as recited in claim 1 , wherein the wire is a K-wire.
6. The system as recited in claim 1 , wherein the wire includes a threaded portion configured to engage the internal thread.
7. The system as recited in claim 1 , wherein the non-threaded portion establishes a driver recess, and further wherein the fracture fixation system comprises a driver receivable within the driver recess.
8. The system as recited in claim 1 , wherein the internal thread includes a first length and the non-threaded portion includes a second length that is greater than the first length.
9. The system as recited in claim 1 , wherein the internal thread includes a first diameter and the non-threaded portion includes a second diameter that is different from the first diameter.
10. The system as recited in claim 1 , wherein the locking cap includes an external thread that is a variable angle locking thread.
11. A fracture fixation system, comprising:
a bone plate having a first threaded opening and a second threaded opening;
a screw secured within the first threaded opening;
a locking cap threadably secured within the second threaded opening and including a driver recess and an internal thread;
a driver receivable within the driver recess of the locking cap; and
a k-wire threadably attachable to the internal thread of the locking cap.
12. The system as recited in claim 11 , wherein the k-wire includes a threaded portion and a non-threaded portion proximal of the threaded portion.
13. The system as recited in claim 12 , wherein the threaded portion extends to a pointed trocar tip.
14. The system as recited in claim 11 , wherein the locking cap includes a variable angle locking external thread.
15. The system as recited in claim 11 , wherein the internal thread includes a first length and the driver recess includes a second length that is greater than the first length.
16. The system as recited in claim 11 , wherein the internal thread includes a first diameter and the driver recess includes a second diameter that is greater than the first diameter.
17. The system as recited in claim 8 , wherein the first length and the second length extend in a direction that is parallel to a longitudinal centerline axis of the locking cap.
18. The system as recited in claim 10 , wherein the external thread of the locking cap is a male thread, and the internal thread of the locking cap is a female thread.
19. The system as recited in claim 15 , wherein the first length and the second length extend in a direction that is parallel to a longitudinal centerline axis of the locking cap.
20. A fracture fixation system, comprising:
a bone plate having a plurality of threaded openings;
a locking cap threadably secured within one of the plurality of threaded openings; and
a wire threadably attached to the locking cap,
wherein the locking cap includes a passage having an internal thread and a non-threaded portion proximal of the internal thread,
wherein the internal thread includes a first length, and the non-threaded portion includes a second length that is greater than the first length,
wherein the internal thread includes a first diameter, and the non-threaded portion includes a second diameter that is greater than the first diameter.
