Abstract
Surgical instruments that are configured to couple to a bone anchor assembly to provide a modular platform for carrying out various steps of a surgical procedure, such as spinal rod reduction and derotation, are provided. For example, in one embodiment a surgical instrument can include an outer sleeve terminating in a pair of extensions, an inner sleeve having a proximal threaded portion and a distal translating portion configured to pass through the outer sleeve, and a pair of pivoting arms received in the extensions of the outer sleeve. The pivoting arms can be configured to extend into a channel of the outer sleeve to couple a bone anchor to the outer sleeve, and a proximal end portion of the outer sleeve can include one or more flats configured to engage with another instrument.
