Abstract
An instrument for correction of spinal deformities includes an inner member with a proximal portion configured to receive a corrective force and a distal coupling portion configured to transfer the corrective force to a spinal implant in a vertebra. A slot extends transversely through the coupling portion and is configured to guide a fixation rod into the spinal implant. A threaded sleeve includes an external thread and a thru-bore that slides relative to the proximal portion. An outer member couples with the proximal portion and threadably engages the external thread to apply a reduction force as the outer member rotates relative to the inner member. A reduction blade includes a proximal interlocking portion that removably couples with the threaded sleeve and a distal rod engagement feature configured to engage the fixation rod and transfer the reduction force to reduce the fixation rod into the spinal implant.
