1. An apparatus for retaining spinal vertebrae in a distracted state, the apparatus comprising:
a monolithic first body comprising:
a first handle;
a first jaw extending distally of the first handle; and
a first canulated pin receiving member extending transverse to a longitudinal axis of the first body, wherein the first canulated pin receiving member comprises a tubular body extending from a distal end of the first handle,
wherein at least one of the first handle or the first jaw comprises a first plurality of rib structures defining interstitial spaces;
a monolithic second body pivotably coupled to the first body at an intermediate portion of the first body between the first handle and the first jaw, the second body comprising:
a second handle;
a second jaw extending distally of the second handle; and
a second canulated pin receiving member extending transverse to a longitudinal axis of the second body, wherein the second canulated pin receiving member comprises a tubular body extending from a distal end of the second handle,
wherein at least one of the second handle or the second jaw comprises a second plurality of rib structures defining interstitial spaces; and
a locking assembly coupled to the first handle and the second handle, wherein the locking assembly is configured to selectively retain the first canulated pin receiving member and the second canulated pin receiving member at a plurality of relative spacings.
