Coracoid Clamp

A method of preparing a bone block during a Latarjet procedure using a coracoid clamp, the method comprising:

• providing a coracoid clamp comprising:
• a first elongate arm including a first proximal handle portion and a first distal clamping portion, the first distal clamping portion including a first side and a second side opposite the first side, the first side of the first distal clamping portion defining a first bone block engagement structure configured to engage a planar surface of the bone block, and
• a second elongate arm including a second proximal handle portion and a second distal clamping portion, the second distal clamping portion including a first side and a second side opposite the first side, the first side of the second distal clamping portion defining a second bone block engagement structure configured to engage a non-planar surface of the bone block that is opposite the planar surface,
• wherein the first elongate arm is pivotally coupled to the second elongate arm such that the first and second distal clamping portions are pivotable towards each other, the first distal clamping portion defines a plurality of lumens each extending through the first bone block engagement structure and the second side of the first distal clamping portion, and the first side of the first distal clamping portion defines a lip distal to the first bone block engagement structure,
• positioning the first distal clamping portion on a bone block such that the first bone block engagement structure sits on the planar surface of the bone block and the lip is positioned against a side of the bone block that extends from the planar surface and is adjacent a conjoint tendon;
• engaging the coracoid clamp to urge the second distal clamping portion towards the first distal clamping portion to engage the non-planar surface of the bone block with the second bone block engagement structure and hold the bone block between the first bone block engagement structure and the second bone block engagement structure;
• and
• drilling a hole into the held bone block through each of the lumens.

A coracoid clamp comprising:

• a first elongate arm including a first proximal handle portion and a first distal clamping portion, the first distal clamping portion including a first side and a second side opposite the first side, the first side of the first distal clamping portion defining a first bone block engagement structure configured to engage a planar surface of a bone block;
• and
• a second elongate arm including a second proximal handle portion and a second distal clamping portion, the second distal clamping portion including a first side and a second side opposite the first side, the first side of the second distal clamping portion defining a second bone block engagement structure configured to engage a non-planar surface of the bone block opposite the planar surface,
• wherein the first elongate arm is pivotally coupled to the second elongate arm such that the first and second distal clamping portions are pivotable inwards towards each other with the first side of the first distal clamping portion defining an inward facing side of the first distal clamping portion and the second side of the first distal clamping portion defining an outward facing side of the first distal clamping portion,
• wherein the first distal clamping portion defines a lumen extending through the first bone block engagement structure and the second side of the first distal clamping portion,
• wherein the first bone block engagement structure comprises a plurality of first teeth each extending inwards to define a free end, the free ends of the first teeth being configured to engage the planar surface of the bone block, and
• wherein the first side of the first distal clamping portion defines a lip distal the first bone block engagement structure, the lip extending inwards to define a free end, the free end of the lip being located further inwards than the free end of each of the first teeth.
