US 2021/0259749 A1 · A DEVICE AND METHOD FOR FIXATION OF BONE FRAGMENTS IN AN OSTEOTOMY PROCEDURE

Abstract

The present disclosure relates to a device and method for the fixation of bone fragments in an osteotomy procedure. The device includes a first screw including a shank and an external thread for cortical fixation in the bone body fragment and an opening extending transversely through the shank. The device also includes a second screw including a shank and an external thread for cortical fixation in the bone head fragment for relative fixation of the bone body fragment and the bone head fragment. The shank of the second screw being locatable within the transverse opening of the first screw. The disclosure also relates to a jig mountable to the first screw and including one or more guides to align with the one or more transverse openings through the first screw.

Dependent claims

A fixation device for fixing bone head and bone body fragments in an osteotomy procedure, the device including:

a first screw including a shank and an external thread for cortical fixation in the bone body fragment;
the first screw including an opening extending transversely through the shank;
a second screw including a shank and proximal and distal external threads for oblique cortical fixation in the bone body fragment and for cortical fixation in the bone head fragment for relative fixation of the bone body fragment and the bone head fragment;
and

2 more elements

A surgical method for fixing bone head and bone body fragments in an osteotomy procedure for correcting hallux valgus deformity, the method including:

inserting a first screw mediolaterally in a proximal metatarsal bone body fragment for bi-cortical fixation,
inserting a second screw including a shank and proximal and distal external threads proximally and obliquely through the medial cortex of the proximal metatarsal bone body fragment and through an opening extending transversely through the shank of the first screw and distally traversing the lateral cortex of the bone body fragment and entering the lateral cortex of the bone head fragment for oblique cortical fixation in the bone body fragment and for cortical fixation in the bone head fragment for relative fixation of the body and head fragments.
