Abstract
A polyaxial offset lateral connector includes a body, an insert, and a connecting shaft. The body has a base that defines a receptacle and walls that extend from the base to define a saddle. The insert includes a cup and a pin that extends from a bottom surface of the cup. The connecting shaft has a connection portion and a neck extending from the connecting shaft to a ball. The ball is received within the receptacle of the body and defines a pin passage therethrough. The pin is the insert is received within the pin passage of the ball to prevent translation of the connecting shaft relative to the body.
Claims20
A polyaxial offset lateral connector comprising:
- a body having a base defining a receptacle and walls extending from the base to define a saddle;
- an insert including a cup and a pin extending from a bottom surface of the cup;
- and
- a connecting shaft having a connection portion extending away from a ball, the ball received within the receptacle of the body and defining a pin passage therethrough, the pin of the insert received within the pin passage of the ball to prevent translation of the connecting shaft relative to the body.
A spinal construct comprising:
- a spinal rod defining a longitudinal axis;
- one or more screws configured to secure the spinal rod to a spine of patient such that the spinal rod extends along the spine;
- and
- a polyaxial offset lateral connector including:
- a body having a base defining a receptacle and walls extending from the base to define a saddle, the saddle configured to secure the body to the spinal rod;
- an insert including a cup and a pin extending from a bottom surface of the cup;
- and
- a connecting shaft having a connection portion extending away from a ball, the ball received within the receptacle of the body and defining a pin passage therethrough, the pin of the insert received within the pin passage of the ball to prevent translation of the connecting shaft relative to the body;
- the connecting portion extending away from the ball in a direction substantially transverse to the longitudinal axis.
A method of securing spinal construct to a spine of a patient, the method comprising:
- securing a first screw to a first vertebra of the spine;
- securing a second screw to a second vertebra of the spine;
- securing a spinal rod in a head of the first screw and a head of the second screw, the spinal rod extending along the spine;
- and
- receiving the spinal rod in a saddle of a polyaxial offset lateral connector, the polyaxial offset lateral connector including:
- a body having a base defining a receptacle and walls extending from the base to define the saddle, the saddle configured to secure the body to the spinal rod;
- an insert including a cup and a pin extending from a bottom surface of the cup;
- and
- a connecting shaft having a connection portion extending away from a ball, the ball received within the receptacle of the body and defining a pin passage therethrough, the pin of the insert received within the pin passage of the ball to prevent translation of the connecting shaft relative to the body;
- the connecting portion extending away from the ball in a direction substantially transverse to the longitudinal axis.
