View Edit Delete	NXT-5PROV NXT-5, 6, 7, 8	In patients who have received a joint prosthesis at the joint at the distal end of a long bone, existing intramedullary fixation devices (IMDFs), such as nails, rods, and the like can make retrograde and antegrade deployment from a distal/proximal end of the long bone challenging or not possible using conventional techniques and instrumentation. A simple, easy IMDF that facilitates retrograde/antegrade deployment from a distal/proximal end of the long bone is needed.	38	Added by DJM 8 2021	8/16/21, 12:00 AM

Inferior or caudal means toward the feet or tail. Medial means toward the midline of a body, particularly toward a plane of bilateral symmetry of the body. Lateral means away from the midline of a body or away from a plane of bilateral symmetry of the body. Axial means toward a central axis of a body. Abaxial means away from a central axis of a body. Ipsilateral means on the same side of the body. Contralateral means on the opposite side of the body. Proximal means toward the trunk of the body. Proximal may also mean toward a user or operator. Distal means away from the trunk. Distal may also mean away from a user or operator. Dorsal means toward the top of a body part such as a foot. Plantar means toward the sole of the foot. Antegrade means forward moving from a proximal location/position to a distal location/position or moving in a forward direction. Retrograde means backward moving from a distal location/position to a proximal location/position or moving in a backwards direction.	36	Added by DJM 8 2021	8/16/21, 12:00 AM
View Edit Delete	NXT-5PROV NXT-5, 6, 7, 8	A standard system of three mutually perpendicular reference planes is employed. A sagittal plane divides a body into right and left portions. A coronal plane divides a body into anterior and posterior portions. A transverse plane divides a body into superior and inferior portions. A mid-sagittal, mid-coronal, or mid-transverse plane divides a body into equal portions, which may be bilaterally symmetric. The intersection of the sagittal and coronal planes defines a superior-inferior or cephalad-caudal axis. The intersection of the sagittal and transverse planes defines an anterior-posterior axis. The intersection of the coronal and transverse planes defines a medial-lateral axis. The superior-inferior or cephalad-caudal axis, the anterior-posterior axis, and the medial-lateral axis are mutually perpendicular.	35	Added by DJM 8 2021	8/16/21, 12:00 AM

The second bend 120 may define a second angle 130 between the body 128 and an offset axis 122 (i.e., a longitudinal axis of the offset section 116). The second angle 130 may be a variety of angles and may range from between about 25 degrees and about 155 degrees. In certain embodiments, the second angle 130 may be about 135 degrees.	52	Added by DJM 8 2021	8/16/21, 12:00 AM
View Edit Delete	NXT-5PROV NXT-5, 6, 7, 8	In one embodiment, the first angle 126 and second angle 130 may be supplementary angles such that joining the first bend 118 and second bend 120 together with the body 128 between them results in the coupling 110 extending in a direction or along an offset axis 122 that is parallel to the longitudinal axis 114. Said another way, the second bend 120 may be angled anteriorly from, or in relation to, the longitudinal axis 114 such that a coupling 110 connected to the second bend 120 extends, or is oriented, in a direction that is parallel to the longitudinal axis 114. An offset axis 122 that passes through a cross sectional center 124 of the coupling 110 and into the second bend 120 is substantially parallel to the longitudinal axis 114.	53	Added by DJM 8 2021	8/16/21, 12:00 AM

In such an embodiment, the coupling 110 and an end of the distal end 104 extends posteriorly from a distal joint of the long bone.	56	Added by DJM 8 2021	8/16/21, 12:00 AM
View Edit Delete	NXT-5PROV NXT-5, 6, 7, 8	The distal end 104 of the intramedullary nail 100 may include one or more openings 132 configured to accept one or more fasteners (e.g., a bone screws) used to lock the intramedullary nail 100 in place, or fix the intramedullary nail 100, in place within the long bone. The one or more openings 132 may include internal threads that engage threads of fasteners or may permit the fasteners to pass through the intramedullary nail 100 and engage bone on an opposite side of the one or more openings 132. One of the one or more openings 132 may be within the body 128 of the offset section 116 and one of the one or more openings 132 may be at another position along the distal end 104. The fastener openings 132 may be configured to accept fasteners driven into the long bone at a variety of angles.	57	Added by DJM 8 2021	8/16/21, 12:00 AM

View Edit Delete	NXT-5PROV NXT-5, 6, 7, 8	The coupling 110 of the distal end 104 serves to connect the intramedullary nail 100 with a driver (See FIG. 3A) for deployment of the intramedullary nail 100. The coupling 110 may use a variety of features and/or interfaces for making a coupling/connection between the coupling 110 and the driver. In the illustrated embodiment, the coupling 110 includes an arrangement of grooves 234 (See FIG. 2C) that accept ridges or “tongues” that may extend from a corresponding driver of an inserter. The grooves 234 engage the tongues to permit the driver to force, or move, the intramedullary nail 100 longitudinally when deploying the intramedullary nail 100. The grooves 234 permit some torque forces to be applied to the coupling 110 to facilitate deployment of the intramedullary nail 100. In certain embodiments, the grooves 234 may engage with the tongues in a friction fit such that the intramedullary nail 100 can be retracted as needed during a deployment procedure. In certain embodiments, the coupling 110 may engage with a driver such that retraction of the driver also retracts the coupling 110 and structures connected to the coupling 110.	59	Added by DJM 8 2021	8/16/21, 12:00 AM

View Edit Delete	NXT-5PROV NXT-5, 6, 7, 8	Figure 2B is a perspective view of the intramedullary nail 202 and adapter 204 of FIG. 2A, according to one embodiment. The intramedullary nail 202 may include a proximal end 206, a distal end 208, and a shaft 210 between them. The shaft 210 may include a longitudinal axis 212. The intramedullary nail 202 may be a straight rigid intramedullary nail and/or may include a bow that follows a natural curve of the long bone of a patient. The intramedullary nail 202 may be similar to the intramedullary nail 100 described above, except that the distal end 208 does not include an offset section 116. The intramedullary nail 202 may include one or more openings 214 similar in placement, function, and operation to the one or more openings 132 described above in relation to the intramedullary nail 100.	63	Added by DJM 8 2021	8/16/21, 12:00 AM
View Edit Delete	NXT-5PROV NXT-5, 6, 7, 8	The distal end 208 may include a first coupling 216. The first coupling 216 is configured and/or arranged to engage with the adapter 204. The first coupling 216 enables longitudinal forces and/or torsional forces placed on the adapter 204 to transfer to the distal end 208 for deployment of the intramedullary nail 202.	64	Added by DJM 8 2021	8/16/21, 12:00 AM
View Edit Delete	NXT-5PROV NXT-5, 6, 7, 8	The adapter 204 includes a second coupling 218, a third coupling 220, and a body 222. The second coupling 218 is configured to engage the first coupling 216. The third coupling 220 is configured to engage a fourth coupling of an inserter (See FIG. 3A). The body 222 may include a first bend 224 at one end and a second bend 226 at an opposite end. The first bend 224 sits between the second coupling 218 and the body 222 and directs the body 222 posteriorly in relation to the second coupling 218 and the longitudinal axis 212 of the intramedullary nail 202. The second bend 226 sits between the body 222 and the third coupling 220 and directs the body 222 posteriorly in relation to the third coupling 220 and the longitudinal axis 212 of the intramedullary nail 202. In certain embodiments, the second bend 226 directs the third coupling 220 such that the third coupling 220 extends from the body 222 parallel to the longitudinal axis 212. In one embodiment, the first bend 224 is angled posteriorly from the longitudinal axis 212 and the second bend 226 is angled anteriorly from the longitudinal axis 212 such that the third coupling 220 extends parallel to the longitudinal axis 212.	65	Added by DJM 8 2021	8/16/21, 12:00 AM
