    • DESCRIPTION OF VARIOUS ASPECTS
  • The following description is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
  • Referring to FIGS. 1, 1A, and 2, an exemplary variable angle bone fixation assembly 100 is illustrated according to the present teachings. The bone fixation assembly 100 can include a receiver 102 defining an opening 118 along a first axis “X”, and a bone fastener 104. The bone fastener 104 can be assembled on the receiver 102 for variable angle angulation relative to the first axis X on an angulation cone of angle α, as illustrated in FIG. 1A. The bone fastener 104 can include a head 108 and a bone-engaging portion 106, which can be shaped as a screw or other anchor, as shown in FIG. 5. The bone-engaging portion 106 can include, for example, a plurality of threads 107 and an anchoring tip 109. The head 108 can include a circumferential exterior groove 111 for engaging a retention member, such as a fastener ring 112, shown in FIG. 9, as discussed below.
  • Referring to FIGS. 3-10, the receiver 102 can include two substantially parallel arms 126 extending in a direction away from the fastener 104. The arms define a channel 128 along a second axis “Y” generally perpendicular to the first axis X. The channel 128 can be shaped to receive an elongated fixation member 130, such as, for example, a spinal fixation rod or other fixation bar, as shown in FIG. 1. The interior surface of the arms 126 can include a thread pattern or other interlocking form 132, such as a helically-wound interlocking form similar to the one disclosed and described in U.S. Pat. No. 6,726,689, filed Sep. 2, 2002, the disclosure of which is incorporated herein by reference. It will be appreciated that other thread forms can also be used. The interlocking form 132 can mate with a closure member (not shown) having a corresponding interlocking form for securing the fixation member 130 in the receiver 102 such that radial splaying of the arms 126 can be operatively resisted.
  • Referring to FIGS. 3-6, the receiver 102 can include an articulation surface 120 at a lower portion of the opening 118 and adjacent a lower end 122 thereof. The articulation surface 120 can articulate with a corresponding curved exterior surface 124 of one or more discrete supporting augments 110. The conforming articulating surfaces 120, 124 can be portions of generally spherically surfaces or other surfaces that can provide desired variable angle fixation. Each supporting augment 110 can include a curved interior surface 125 which can be shaped to conform to at least a portion of the head 108 of the bone fastener 104. Referring to FIG. 6, in one aspect, each supporting augment 110 can include upper and lower substantially planar surfaces 143 a, 143 b, first and second oppositely inclined substantially planar end surfaces 140 a, 140 b, and an upper curved cutout or notch 136 adjacent to first end surface 140 a. The upper surface 143 a can define a sharp corner 145 b with the second end surface 140 b, and a blunt or rounded corner 145 a with the first end surface 140 a.
  • The supporting augments 110 can be positioned relative to each other such that upon assembly each of the first and second end surfaces 140 a, 140 b of one supporting augment 110 can mate with the second and first end surfaces 140 b, 140 a, respectively, of the other supporting augment 110, thereby completing an annular curved surface with a 360-degree circumference. The shape of the supporting augments 110 can be defined for ease of assembly and angulation during assembly. For example, during assembly, the supporting augments 110 can be positioned such that the sharp corner 145 b of each supporting augment 110 rides on the notch 136 of the other supporting augment 110, such that the supporting augments 110 overlap partially, and the overall size/volume of the resulting configuration is smaller during assembly than the size of the assembled supporting augments 110.
  • Referring to FIGS. 3, 6 and 9, each supporting augment 110 can also include a circumferential interior groove 134 shaped for partially receiving the fastener ring 112. The fastener ring 112 can be a substantially flat and compliant split ring with an outer boundary 113 and an inner boundary 115. In assembly, at least a portion of the outer boundary 113 of the fastener ring 112 can be engaged with the interior groove 134 of the supporting augment 110. The inner boundary 115 of the fastener ring 112 can engage the exterior groove 111 of the head 108 of the bone fastener 104.
  • Referring to FIGS. 3, 7, and 8, the bone fixation assembly 100 can also include a cap 116, which can engage an upper portion of the head 108. The cap 116 can include a circumferential exterior cap groove 117 for engaging a cap ring 114. The cap ring 114 can be a compliant split ring and can be positioned in engagement between the cap groove 117 and an interior groove or slot 119 defined in the receiver 102. Pressing the cap 116 against the head 108 of the bone fastener 104 with the fixation member 130 can prevent angulation of the bone fastener 104 relative to the receiver 102, thereby retaining the fastener 104 in a fixed orientation.
  • The bone fixation assembly 100 can be assembled during or before the surgical procedure. Generally, the head 108 of the bone fastener 104 can be inserted first into the opening 118. At least one supporting augment 110 can be inserted into the opening 118, and coupled to the head 108 of the bone fastener 104. The angle α of the bone fastener 104 relative to the first axis X can then be varied by articulating the supporting augment 110 relative to the articulation surface 120.
  • In one exemplary aspect, the fastener ring 112 can be assembled on the exterior groove 1 11 of the head 108 of the bone fastener 104. The head 108 with the fastener ring 1 12 thereon can be inserted into the receiver 102 through the lower end 122 of the opening 118, and can be pushed above its final seating position to facilitate assembly, as necessary. The supporting augments 110 can then be inserted from an upper end 123 of the receiver 102 and can be pushed toward the fastener ring 112 while the bone fastener 104 is pulled down, until the supporting augments 110 engage the fastener ring 112 and the bone fastener 104 is seated in engagement with the receiver 102. In this position, the bone fastener 104 can freely angulate relative to axis X, but can not be removed from the receiver 102 either through the lower end 122 or through the upper end 123. For facilitating insertion the supporting augments 110 can be arranged with partial overlapping therebetween, as discussed above. In another aspect, the supporting augments 110 can be inserted into the receiver 102 through the lower end 122 of the opening 118, and manipulated into engagement with the fastener ring 112.
  • The cap 116 with the cap ring 114 can be inserted from the upper end 123 of the receiver 102 such that the cap ring 114 engages the interior slot 119 of the receiver 102. For a particular application, such as spinal fixation, a rod or other longitudinal fixation member 130 can be positioned along the channel 128 and pressed against the cap 116 with a compression member (not shown). Pressing the cap 116 against the head 108 with the compression member secures the bone fastener 104 in a desired orientation.
  • It will be appreciated that the modularity and shape of the various parts of the bone fixation assembly 100 can provide a compact (non-bulky) bone fixation device, which can be easily assembled during the surgical procedure, or can also be at least partially pre-assembled. Furthermore, the bone fixation assembly 100 can be easily configured for accommodating various surgical situations at the site of operation as desired by the surgeon.
  • The fixation assembly can be formed from biocompatible materials, such as, for example, metallic materials.
  • The foregoing discussion discloses and describes merely exemplary arrangements of the present invention. One skilled in the art will readily recognize from such discussion, and from the accompanying drawings and claims, that various changes, modifications and variations can be made therein without departing from the spirit and scope of the invention as defined in the following claims.
