Abstract
An implantable orthopedic device. The device includes: a proximal anchor, configured to be implanted inside a first metatarsal; the anchor having a collar larger than the opening in a metatarsal in which the proximal anchor is implanted; the collar preventing cable to bone contact; a distal anchor, configured to be implanted inside a second metatarsal, adjacent to the first metatarsal; the distal anchor having a male thread, a nut threadable onto the male thread of the distal anchor, and a cord mechanically interconnecting the proximal and distal anchors. A shock absorber includes an elongate housing threadedly positioned within the anchor; the shock absorber accommodates a cord holder mechanically connected to the housing via a damping member, the cord holder is freely rotatable within the housing to prevent the cord from twist kinking when the housing is rotated to adjust a tension force.
