Abstract
A spinal construct is provided which includes a bone penetrating member, a receiver and a spherical connector. The bone penetrating member has a head and a tip. The receiver extends along a longitudinal axis between a proximal end portion and a distal end portion. The proximal end portion is configured to receive an elongated member, such as a vertebral rod. The distal end portion of the receiver includes an opening configured for receiving a spherical connector. The spherical connector is configured to receive the head of the bone penetrating member. The spherical connector can have a truncated spherical shape and contains an upper portion, a middle portion and a lower portion with an axial bore through it.
Claims20
A spinal construct comprising:
- a bone penetrating member having a head and a tip opposite the head,
- a receiver extending along a longitudinal axis between a proximal end portion and a distal end portion of the receiver, the proximal end portion configured to receive an elongated member and the distal end portion comprising an opening for receiving
- a spherical connector, the spherical connector configured to receive the head of the bone penetrating member.
A spinal construct comprising:
- a bone penetrating member having a head and a tip opposite the head,
- a receiver extending along a longitudinal axis between a proximal end portion and a distal end portion of the receiver, and
- a base having an upper end and a lower end, the base rotatably mounted to the distal end portion of the receiver, wherein the proximal end portion of the receiver is configured to receive an elongated member and (i) the base is configured to receive a spherical connector or (ii) the distal portion the receiver is configured to receive a spherical connector or (iii) the distal portion of the receiver and the base are configured to receive a spherical connector, the spherical connector adapted to receive the head of the bone penetrating member.
A spinal construct comprising:
- a bone penetrating member having a head and a tip opposite the head,
- a receiver extending along a longitudinal axis between a proximal end portion and a distal end portion of the receiver, the receiver comprising:
- an upper leg and a lower leg opposite the upper leg, the lower leg including a foot portion extending from one end thereof, the upper leg extending transversely to the longitudinal axis;
- an intermediate portion opposite the foot portion, the intermediate portion extending between the upper leg and the lower leg, the lower leg and the intermediate portion defining a cavity configured to receive a spherical connector, the spherical connector configured to receive the head of the bone penetrating member.
