US 2025/0025219 A1 · ROTATIONAL GUIDED GROWTH DEVICES, SYSTEMS, AND METHODS

Abstract

A tether assembly may be attached to a bone to correct a rotational deformity. The bone may have a growth plate that separates a first section of the bone from a second section of the bone. The tether assembly may have a tether member with a first end, a second end, and a central portion extending between the first end and the second end. The first end may have a closed outer wall that defines and fully bounds a first aperture. The second end may have an open outer wall that defines and partially bounds a second aperture. The open outer wall may define a slot in communication with the second aperture. The first and second ends may be securable to the first and second sections of the bone via coupling members inserted through the first and second apertures and anchored in the first and second sections, respectively.

Dependent claims

A tether assembly attachable to a bone comprising a growth plate that separates a first section of the bone from a second section of the bone, the tether assembly comprising:

a tether member comprising:
a first end;
a second end;
and
a central portion extending between the first end and the second end;
wherein:
the first end comprises a closed outer wall that defines and fully bounds a first aperture;
the second end comprises an open outer wall that defines and partially bounds a second aperture, the open outer wall defining a slot in communication with the second aperture;
the first end is configured to be secured to the first section of the bone via a first coupling member inserted through the first aperture and anchored in the first section;
and
the second end is configured to be secured to the second section of the bone via a second coupling member inserted through the second aperture and anchored in the second section.

8 more elements

A method for performing rotational correction on a bone comprising a growth plate that separates a first section of the bone from a second section of the bone, the method comprising:

positioning a tether member of a tether assembly on the bone, the tether assembly comprising:
a first coupling member comprising:
a first head;
and
a first shank comprising a first bone engagement feature configured to retain the first shank in the bone;
a second coupling member comprising:
a second head;
and
a second shank comprising a second bone engagement feature configured to retain the second shank in the bone;
and
the tether member, wherein the tether member comprises:
a first end;
a second end;
and
a central portion extending between the first end and the second end;
with the first coupling member, securing the first end of the tether member to the first section of the bone;
and
with the second coupling member, releasably securing the second end of the tether member to the second section of the bone such that, in response to exertion of a threshold level of tension between the second coupling member and the second end, the second end is released from the second section of the bone.
