Abstract

Systems and methods include solutions for fixation at the rib head for fractures and osteotomies adjacent to the rib head and transverse process. The disclosed rib plates, anchor systems, other implants, and instrumentation may also be applied to mid-rib fractures. The systems and methods may be used in the treatment of rib deformities, including the correction of rib hump deformity via thoracoplasty, as well as general corrections of chest and rib deformities. Systems and methods herein may be used in chest wall reconstructions due to trauma, cancer, or deformity.

First claim

What is claimed is:

1. An anchor assembly for attaching to a rib comprising:
a bone plate having at least one screw hole for receiving a bone screw to be inserted into the rib, the bone plate comprising a first end and a second end opposite the first end, wherein a length of the bone plate extends from the first end to the second end along a first longitudinal axis;
a threaded shaft extending from the bone plate along a second longitudinal axis generally parallel to or coaxial with the first longitudinal axis;
a clamp having a split body defining a pocket and first and second extensions each extending from the pocket and terminating at a first end defining a through hole sized to accept the threaded shaft, wherein the first extension comprises a first surface extending from the pocket to the first end and the second extension comprises a second surface extending from the pocket to the first end, the second surface facing the first surface;
a flexible collet configured to be seated in the pocket and adapted to polyaxially receive a rod in the pocket wherein the flexible collet is a spherical collet having a spherical surface defined between an upper opening and a lower opening, and the spherical surface includes a plurality of first slits open to the upper opening and a plurality of second slits open to the lower opening, wherein each first slit is disposed between two adjacent second slits; and
a lock for locking the split body to the threaded shaft, wherein, when the lock is locking the split body to the threaded shaft, the first surface is angled relative to the second surface.

2. The anchor assembly of claim 1 , further comprising a male locking spline disposed above the bone plate, wherein one of the through holes includes a female locking spline for engagement with the male locking spline so as to rotationally fix the split body of the clamp to the threaded shaft.

3. The anchor assembly of claim 1 , wherein the lock includes a locking nut configured to be threadably coupled to the threaded shaft to bring the first and second extensions together.

4. The anchor assembly of claim 3 , wherein when the first and second extensions are brought together, the extensions compress the flexible collet to fix the rod to the clamp.

5. The anchor assembly of claim 1 , wherein the flexible collet includes a plurality of flexures configured to apply a clamping force on the rod.
