Orthopedic Implant for Treatment of Bone Deformities

摘要

An implantable device 20 comprises: (a) a proximal anchor 200, configured to be implanted inside a first metatarsal; said anchor having a collar larger than the opening in said metatarsal in which said proximal anchor is implanted; said collar preventing cable to bone contact (b) a distal anchor 300, configured to be implanted inside a second metatarsal, adjacent to said first metatarsal; said distal anchor having a male thread; (c) a nut threadable onto said male thread of the distal anchor; (d) a cord 110 mechanically interconnecting said proximal and distal anchors. Said shock absorber comprises an elongate housing threadedly positioned within said anchor; said shock absorber accommodates a cord holder mechanically connected to said housing via a damping member, thereat said cord holder is freely rotatable within said housing to prevent said cord from twist kinking when said housing is rotated to adjust a tension force.
