- a wire tensioning fixation bolt 1000 is described herein which can be attached directly to a frame such as a circular fixator 1050 (as shown in FIG. 7), or indirectly attached to the circular fixator 1050 via an offsetting post (not shown), such that the post is attached to a ring 1052 of the circular fixator 1050, and the wire tensioning fixation bolt 1000 is attached to the post at a desired distance from the ring of the circular fixator.
- the wire tensioning fixation bolt 1000 has a built in tensioning mechanism. Once the wire tensioning fixation bolt 1000 is attached to the circular fixator 1050, and the wire 1016 is locked to the bolt 1000, the built-in tensioning mechanism can be activated to apply a prescribed tension to the wire, without requiring any separate wire tensioner.
- the wire tensioning fixation bolt 1000 can use used to fix a limb of a patient for a variety of orthopedic procedures, including Charcot, medial column fusion, fractures, and treatment of arthritis.
- FIGS. 1-7 show a first embodiment of a wire tensioning fixation bolt 1000.
- the wire tensioning fixation bolt 1000 is a fixation device comprising a first body 1002 having a threaded end 1006, a longitudinal axis 1008 and a bore 1010 perpendicular to the longitudinal axis 1008.
- a second body 1004 is slidably received in the bore 1010.
- the second body 1004 includes a wire shaft body 1005 and a threaded portion 1012.
- the second body 1004 has an exterior threaded portion 1012 and an interior passage 1014 for receiving a pin or wire 1016.
- the bore 1010 of the first body is larger in diameter than the outer diameter of the threaded portion 1012 of the second body 1004, to allow the threaded portion 1012 of the second body 1004 to slide longitudinally within the bore 1010, without engaging the threads of the threaded portion 1012.
- the second body 1004 has a wire shaft body 1005 with a wire locking device 1018 for retaining the pin or wire 1016 in fixed relationship to the second body 1004.
- An advance nut 1020 engages the exterior thread 1012 of the second body 1004.
- the advance nut 1020 abuts the first body 1002. Rotation of the advance nut moves the threaded portion of the second body 1002, for moving the wire locking device 1018 away from the first body 1002, for tensioning the pin or wire 1016.
- the interior passage 1014 of the second body 1004 has at least one curved surface 1022 and at least one flat surface 1024. In some embodiments, as best seen in FIG. 5, the interior passage 1022 is approximately tear-drop shaped. In some
- the interior passage 1014 has two flat surfaces 1024 with an angle a therebetween.
- the angle a is in a range from about 30 degrees to about 170 degrees between the two flat surfaces. In some embodiments, the range is from about 30 degrees to about 135 degrees.
- angle a could be 27, 33, 45, 47, 132, or 167.
- the two flat surfaces 1024 provide for three points of contact between the pin or wire 1016, the interior passage 1022, and the locking bolt 1026 of wire locking device 1018.
- the locking bolt 1026 can have a flat end surface for engaging the pin or wire 1016.
- the wire locking device 1018 comprises a locking bolt
- the second body 1004 has a groove or flat surface 1036 on the threaded portion 1012 of the second body 1004.
- the first body 1002 has a pin 1034 for engaging the groove or flat surface 1036.
- the pin 1034 limits rotation of the second body 1004 (about the longitudinal axis of the threaded portion 1012) relative to the first body 1002 to a predetermined angle (e.g., an angle from 10 degrees to 20 degrees), while permitting the second body 1004 to translate relative to the first body 1002.
- FIG. 7 is an isometric view showing the wire tensioning fixation bolt 1000 attached directly to a circular fixator 1052.
- the apparatus comprises: a circular fixator 1050 having at least one ring 1052 and a wire tensioning fixation bolt 1000.
- the wire tensioning fixation bolt 1000 includes: a first body 1002 having a longitudinal axis 1008 , a bore 1010 perpendicular to the longitudinal axis 1008, and a mounting device 1006 for detachably mounting the first body 1002 to the ring 1052.
- the circular fixator 1050 has a ring 1050 with an elongated slot 1054.
- the ring 1050 has a recessed surface 1056 on a top surface of the ring 1050, adjacent to each side of the slot 1054.
- the ring 1050 has a plurality of scallops or pockets 1058 for receiving one or more fixation devices, such as the wire tensioning fixation bolt 1000 and/or other wire fixation devices.
- the wire tensioning fixation bolt 1000 can be used with other types of circular fixator, such as a frame having rings with fixed mounting holes (e.g, "SIDEKICK®” circular fixator, sold by Wright Medical Technologies of Memphis, TN).
- a second body 1004 is slidably received in the bore 1010 of the first body.
- the second body 1004 has an exterior thread 1012 and an interior passage 1014 for receiving a pin or wire 1016.
- the exterior thread 1012 is engaged by the nut 1020, but is not engaged by the smooth surface of bore 1010.
- the advance nut 1020 engages the exterior thread 1012 and abuts the first body 1002.
- the second body 1004 moves in the opposite direction, so that the wire shaft body 1005 moves away from the first body 1002.
- the jam nut 1060 limits travel of the advance nut 1020, and thus limits the elongation of the pin or wire 1016. Thus, the jam nut 1060 limits the amount of tension that can be applied to the pin or wire 1016 by advancing the advance nut 1020.
- the second body 1004 has a wire locking device 1018 for retaining the pin or wire 1016.
- the interior passage 1014 has two flat surfaces
- the wire locking device 1018 comprises a locking bolt 1026 threadably received by the second body 1004, and positioned for forcing the pin or wire 1016 against the at least one flat surface 1024 when the locking bolt 1026 is advanced.
- the first body 1002 has an opening
- the feature includes a pin or mark 1030 affixed to a side of the second body 1004, and the first body 1002 has a plurality of calibration markings 1032 adjacent the opening 1028. If a pin is used, the pin can be flush with the surface of the first body 1002 or recessed. Alternatively, feature 1030 can be a laser mark similar to laser marks 1032. A change in position of the feature 1030 relative to the opening 1028 is indicative of an elongation of the pin or wire 1016 due to the tensioning.
- the tension can be calculated by the following equation:
- T is the tension force
- E is the (Young's) elastic modulus of the material of the pin or wire
- £ is the strain, i.e., the ratio of the elongation to the original length of the pin or wire (AL/L)
- L is the original length
- AL is the elongation
- A is the cross-sectional area of the pin or wire.
- the elongation can be measured by counting the number of markings 1032 passed by the features 1030 during tensioning.
- the device is calibrated by taking at least one elongation measurement for a given pin or wire 1016 of a given material. Since all of the terms in the right hand side of equation (1) are constants, except for £, equation (1) can be rewritten as:
- the second body 1004 has a groove or flat surface 1036
- the first body 1002 has a pin 1034 for engaging the groove or flat surface 1036, so as to permit the second body 1004 to translate relative to the first body 1002.
- the pin 1034 is positioned to limit rotation of the second body 1004 relative to the first body 1002 to a predetermined angle, such as 10 to 20 degrees.
- the wire tensioning fixation bolt 1000 can be made of a variety of materials, such as, but not limited to, stainless steel, aluminum, or titanium.
- a fixation method comprises positioning a first body 1002 of a wire tensioning fixation bolt 1000 on a frame, such as a circular fixator 1050.
- the wire tensioning fixation bolt 1000 has a first body 1002 and a second body 1004 slidably received in the first body.
- the first body 1002 of the wire tensioning fixation bolt 1000 is fixed to a ring
- the first body 1002 has a bolt 1006 and is fixed to the frame 1050 with a nut.
- the wire tensioning fixation bolt 1000 is positioned on the frame, so that a wire locking device 1018 of a wire shaft body 1005 of the second body 1004 is positioned radially outward, away from the center of the ring 1052, and thus away from the patient's limb.
- the arrangement of the wire tensioning fixation bolt 1000 on the frame 1050 is shown in FIG. 7.
- the first body 1002 has a second body 1004 of the wire tensioning fixation bolt
- the second body 1004 has a threaded portion 1012.
- the second body 1004 can slide longitudinally within the bore 1010 of the first body 1002.
- the threaded portion 1012 has a flat portion or groove 1036.
- the alignment member or pin 1036 permits longitudinal motion of the second body 1004, while preventing rotation beyond a small predetermined value (e.g., 10 to 20 degrees).
- the nut 1020 and wire shaft body 1005 are moved along the threaded portion 1012 of the second body 1004, all the way (radially inward) towards the first body 1002, until the nut 1020 abuts the first body 1002, and the wire shaft body 1005 abuts the nut 1020.
- This position is shown in FIGS. 2, 3 and 6. This is a fully retracted position, which allows the surgeon the greatest range of tension.
- the second body 1004 is locked to a pin or wire 1016 inserted into a bone of a patient.
- the locking step includes inserting the pin or wire 1016 through a passage 1014 in the second body 1004, and driving a locking member 1026 against a side surface of the pin or wire 1016.
- the driving step includes driving a wire locking bolt 1026 through a threaded passage or opening 1062 in the second body 1004.
- the passage 1010 has two flat surfaces 1024 oriented at oblique angles with respect to an axis 1064 of the locking member, and the driving step includes gripping the pin or wire 1016 between the locking member (bolt) 1026 and the two flat surfaces 1024.
- the wire tensioning fixation bolt 1000 is ready to tension the pin or wire 1016.
- the nut 1020 is advanced along the threaded portion 1012 of the second body 1004, towards the first body 1002, and away from the wire shaft body 1005.
- the step of advancing the nut increases a distance between the first body 1002 and the locking member 1018 of the second body 1004. This causes the wire shaft body 1005 to move radially outward from the patient's limb (e.g., foot), so as to tension the pin or wire 1016.
- the second body 1004 has a groove or flat surface 1036
- the first body 1002 has a pin or alignment member 1034 for engaging the groove or flat surface 1036
- the step of advancing the nut 1020 includes translating the second body 1004 relative to the first body 1002 to increase a distance between the first body and the locking member, while the pin 1034 limits rotation of the second body 1004 relative to the first body 1002 to a predetermined angle a.
- the first body 1002 has an opening 1028 in a side or top surface thereof, and the second body 1004 has a feature 1030 exposed within the opening 1028.
- the position of the feature 1030 relative to the opening 1028 is indicative of an elongation of the pin or wire 1016 due to the tensioning.
- the feature includes a pin affixed to a side of the second body.
- the first body has a plurality of calibration markings adjacent the opening.
- FIGS. 9 and 10 show a second embodiment of a locking device 1070, which can be included in place of the locking device 1018.
- the wire shaft body 1005 of FIG. 1 is replaced by a wire shaft body 1075 having a rectangular channel 1078.
- the locking device 1070 has two components: a rotating inner portion having a threaded member 1071 attached to a T-member 1072 having a T-shaped cross section.
- the T-member 1072 can have a disk shaped bottom portion forming the T-shaped cross-section.
- a rectangular outer portion 1073 has a T-shaped channel 1079 adapted to receive the T-member 1072.
- the rectangular outer portion 1073 is adapted to translate up and down within the rectangular channel 1078 without rotating.
- the threaded member 1071 and T-member 1072 advance or retract in the vertical direction, causing the rectangular outer portion 1073 to rise or descend.
- the rectangular outer portion 1073 has a V-shaped or curved groove 1077 on its bottom surface to engage and apply a locking force against the pin or wire 1016. This method helps to prevent damage to the pin or wire 1016 while tightening the threaded member 1071, because the groove 1077 of the rectangular outer portion 1073 (which contacts the pin or wire 1016) only translates up and down while loosening or tightening of the threaded member 1071.
