1. A method for implanting a spacer between adjacent spinous processes, the method comprising
inserting the spacer between the adjacent spinous processes, wherein the spacer comprises a body, a first arm coupled to the body, a second arm coupled to the body, and an actuator assembly coupled to the body, wherein each of the first and second arms is configured for receiving a spinous process and comprises a proximal caming surface and a distal portion configured for receiving the spinous process; and
rotating a shaft of an actuator assembly to move an actuator of the actuator assembly to move the first and second arms from an undeployed configuration to a deployed configuration in which the first and second arms receive the adjacent spinous processes, wherein the shaft of the actuator assembly comprises at least one bearing surface maintaining contact with each of the proximal caming surfaces as the first and second arms are moved from the undeployed configuration to the deployed configuration.
