Canulated titanium implant for correcting flat feet in children

A canulated titanium implant for correction of flat feet in children, comprising:

• a first distal end defined by a self-tapping screw-thread (14);
• a second, opposite proximal end defined by a non-threaded smooth conical head (3) connected to the screw-thread, the conical head being free of any grooves extending along a conical surface thereof;
• the head comprising a hexagonal recess (16),
• the screw-thread having a threaded stem portion, the threads extending from the stem along an entire length of the screw-thread to the conical surface of the head, the conical head directly connected to the screw-thread, the threads ending in an angled thickened flat surface, the stem terminating in an apex end point (6), the end point having an apex thread (2) including trisect cuts (2a);
• and
• a canulated tunnel extending both through the head and the screw-thread, wherein,
• a diameter of the head is 8.0 mm±25%,
• a diameter of the screw-thread is 7.1 mm±25%,
• a diameter of the stem is 4.8 mm±25%,
• a diameter of the tunnel is 2.0 mm±25%,
• edges of the apex thread have an angle of 55°, and
• the angled flat surface of the threads of the stem have an angle of 45°±25%,
• the canulated titanium implant configured for correction of flat feet in children.

A canulated titanium implant for correction of flat feet in children, consisting essentially of:

• a first distal end defined by a titanium alloy self-tapping screw-thread (14);
• a second, opposite proximal end defined by a titanium alloy non-threaded smooth conical head (3) connected to the screw-thread, the conical head being free of any grooves extending along a conical surface thereof;
• the head comprising a hexagonal recess (16),
• the screw-thread having a threaded stem portion with an overall cylindrical shape, the threads extending from the stem along an entire length of the screw-thread to the conical surface of the head, the conical head directly connected to the screw-thread, the threads ending in an angled flat surface, the stem terminating in an apex end point (6), the end point having an apex thread (2) including trisect cuts (2a);
• and
• a canulated tunnel extending both through the head and the screw-thread,
• wherein the head is connected to the screw-thread free of any narrowing neck therebetween,
• the canulated titanium implant configured for correction of flat feet in children.
