The implant system includes A proximal extension having a hollow interior and a distal extension configured to be received within the hollow interior of the proximal extension. The implant system also includes a locking element configured to lock the distal extension from moving with respect to the proximal extension. The distal extension is configured with ratchet teeth on a top surface for interacting with a distractor instrument for contacting or distracting the distal extension with respect to the proximal extension. The proximal extension and distal extension are configured to receive clamping elements for coupling to the implant to anatomical regions of the body. ## Claims ### Claim 1 An implant system for correcting deformities comprising: a proximal extension attached to a first rib hook, the first rib hook including a first set screw and a first cam mechanism; a distal extension configured to be received by the proximal extension, wherein the distal extension is attached to a second rib hook; and a locking element configured to lock the proximal extension and distal extension together; wherein the first rib hook is configured to receive a first band therein, and wherein the first cam mechanism is configured to provisionally lock the first band to the first rib hook and after the band is provisionally locked, the first set screw is configured to lock the first band to the first rib hook. ### Claim 2 (depends on 1) The implant system of claim 1, wherein the first rib hook includes a first loop and the second rib hook includes a second loop. ### Claim 3 (depends on 2) The implant system of claim 2, wherein the second rib hook includes a second cam mechanism. ### Claim 4 (depends on 2) The implant system of claim 2, wherein the distal extension is configured with ratchet teeth on a top surface for interacting with a distractor instrument for contacting or distracting the distal extension with respect to the proximal extension. ### Claim 5 (depends on 4) The implant system of claim 4, wherein the band comprises PET. ### Claim 6 (depends on 1) The implant system of claim 1, wherein the distractor instrument comprises a worm gear. ### Claim 7 (depends on 6) The implant system of claim 6, wherein the worm gear is capable of rotation via a bevel gear train. ### Claim 8 (depends on 1) The implant system of claim 1, wherein the distractor instrument comprises a lock knob. ### Claim 9 (depends on 1) The implant system of claim 1, wherein at least one the first and second rib hooks are c-shaped having a first end and a second end, and the band extends from the first end of the rib hook and loops around to the second end of the rib hook. ### Claim 10 (depends on 1) The implant system of claim 1, wherein a second set screw locks down on a second band to secure the second band in the second rib hook. ### Claim 11 (depends on 1) The implant system of claim 1, wherein the first band extends from a first end to a second end, and a first portion of the first band proximate to the first end is positioned on one side of the first set screw and a second portion of the band proximate to the second end is positioned on another side of the first set screw. ### Claim 12 (depends on 1) The implant system of claim 1, wherein the proximal extension is cylindrical. ### Claim 13 (depends on 1) The implant system of claim 1, wherein the first band forms a closed loop and an inner diameter of the closed loop is adjustable in size. ### Claim 14 An implant system for correcting deformities comprising: a proximal extension; a distal extension configured to be received by the proximal extension, wherein at least one of the proximal extension and the distal extension is attached to a rib hook; a locking element configured to lock the distal extension from moving with respect to the proximal extension; wherein the rib hook is configured to receive a band therein, and wherein a cam mechanism is configured to provisionally lock the band to the rib hook and after the band is provisionally locked, a set screw is configured to lock the band to the rib hook. ### Claim 15 (depends on 14) The implant system of claim 14, wherein the rib hook comprises a loop. ### Claim 16 (depends on 15) The implant system of claim 15, the distal extension is configured with ratchet teeth on a top surface for interacting with a distractor instrument for distracting the distal extension with respect to the proximal extension. ### Claim 17 (depends on 16) The implant system of claim 16, wherein the band comprises PET. ### Claim 18 (depends on 16) The implant system of claim 16, wherein the rib hook comprises an offset connection to receive a rod member therein. ### Claim 19 (depends on 16) The implant system of claim 16, wherein the distractor instrument comprises a worm gear. ### Claim 20 (depends on 19) The implant system of claim 19, wherein the worm gear is capable of rotation via a bevel gear train.
