Abstract
An implant system, alignment guide, bone fusion system and surgical method for correction of a flat foot or rocker-bottom deformity, such as a Charcot foot. The implant system includes a bone implant and an elongate member. The bone implant includes a proximal end, a distal end, a hole along a longitudinal axis, and at least one opening intersecting the hole. The elongate member includes a first end with a head portion, a second end with a coupling mechanism, and an opening along a longitudinal axis. The coupling mechanism of the elongate member engages the at least one opening to couple the bone implant to the elongate member.
Claims20
An implant system, comprising:
- a bone implant including a proximal end, a distal end, a hole along a longitudinal axis, and at least one opening intersecting the hole;
- and
- an elongate member including a first end with a head portion, a second end with a coupling mechanism, and an opening along a longitudinal axis;
- wherein the coupling mechanism of the elongate member engages the at least one opening to couple the bone implant to the elongate member.
A bone fusion system, comprising:
- an implantable device including a proximal end, a distal end, a longitudinal opening, and at least one hole extending into the longitudinal opening;
- a rod including a first end with a head portion, a second end with an engagement member, and a hole extending along a longitudinal axis;
- and
- an alignment guide including a first end and a second end, the first end of the alignment guide is configured to engage the proximal end of the implantable device and the second end of the alignment guide is configured to couple to the rod.
A surgical method for fixing a patient's joint, comprising:
- selecting a fixation implant and a compression shaft;
- determining a trajectory for the compression shaft;
- inserting the fixation implant into the patient's joint;
- assembling an alignment guide, the alignment guide comprising:
- a drive tube including a longitudinal hole, the drive tube couples to the fixation implant at one end;
- a driver is inserted into the longitudinal hole of the drive tube and couples to the proximal end of the fixation implant;
- an alignment body including a first end, a second end, and a carriage, the carriage is configured to slidingly engage the first end of the alignment body, the second end of the alignment body engages the driver and couples to the drive tube;
- a sleeve including a longitudinal opening, the sleeve mating with the alignment body;
- a first guide including a longitudinal hole, the first guide configured to engage the longitudinal opening in the sleeve;
- a second guide including a longitudinal hole, the second guide configured to engage the longitudinal hole of the first guide;
- positioning the carriage and the sleeve relative to the fixation implant;
- securing the carriage to the alignment body to maintain the sleeve position;
- inserting the first guide and the second guide into the sleeve;
- inserting a guide pin through the second guide and the patient's joint to intersect the fixation implant;
- removing the second guide from the sleeve;
- inserting a drill over the guide pin to ream an opening in the patient's joint;
- removing the drill and first guide from the sleeve;
- inserting the compression shaft over the guide pin, through the sleeve, and into the patient's joint;
- removing the guide pin;
- inserting the compression shaft into the patient's joint;
- and
- disassembling the alignment guide.
