Surgical device for spinal fixation

A spinal fixation system, comprising:

• a receiver configured to receive at least one fixation member, the receiver having a first end defined by opposed arms with a channel therebetween that is configured to receive the at least one fixation member and a second end,
• a hook member operably coupled to the second end of the receiver, the hook member having an open portion that is configured to engage a portion of bone to secure the receiver to the bone without penetrating the bone, the hook member being configured to move relative to the receiver from an open position allowing release of the bone to a closed position securely gripping the bone when the bone is received in the open portion;
• a cam mechanism configured to move the hook member relative to the receiver from the open position to the closed position, the cam mechanism having an arm extending between first and second cam wings, the arm being configured to cause actuation of the cam mechanism when the arm is pivoted from a proximal position to a distal position;
• and
• a closure member insertable between the opposed arms of the receiver and configured to compress the fixation member into the receiver.

A spinal fixation method, comprising:

• inserting a bone into an open portion of a hook member on a distal end of a receiver;
• encircling the bone with a cable attached to the receiver and a distal-most blade portion of the hook member to secure the hook member to the bone without penetrating the bone, the cable extending across the open portion;
• inserting a spinal rod into a channel defined by opposed arms on a proximal end of the receiver of the surgical device;
• and
• rotating a set screw between the opposed arms to secure the spinal rod into the channel.
