Surgical device for use in spinal or musculoskeletal surgery or in simulated surgery and method of using the same

A system for use in spinal or musculoskeletal surgery or in simulated surgery, the system comprising:

• a bone anchor having a head and a shank for anchoring to bone;
• a non-implantable instrument having a first end, a second end, a longitudinal axis extending between the first and second ends, and an engagement surface connectable to the head of the bone anchor to deliver the bone anchor to an implant site;
• and
• a non-implantable detection device movable relative to the instrument;
• wherein when the bone anchor is connected to the instrument, a first angle formed between the longitudinal axis of the instrument and a shank axis of the bone anchor is adjustable, and wherein a position sensor of the detection device is removably positionable in the bone anchor for determining the first angle.

A system for use in spinal or musculoskeletal surgery or in simulated surgery, the system comprising:

• a surgical implant having an attachment surface and an accommodation space;
• a non-implantable instrument having a first portion with a first longitudinal axis, a second portion with a second longitudinal axis that is connected to the first portion, and an engagement surface at the second portion that is connectable to the attachment surface of the surgical implant to deliver the surgical implant to an implant site;
• and
• a non-implantable detection device movable relative to at least the first portion of the instrument, wherein the first and second portions of the instrument are pivotable relative to one another for adjusting a first angle formed between the first and second longitudinal axes, and wherein a position sensor of the detection device is removably positionable in the surgical implant for determining the first angle.
