A derotation reducer linkage with polyaxial locking connector for use with screw reducers/extenders in spinal fusion surgery.

Methods of applying a locking cap to a bone anchor assembly. The bone anchor assembly includes a bone anchor and an elongate rod. The bone anchor includes a body that defines a channel and has a tissue retractor coupled thereto that defines a partial pathway to the channel.

A sacroiliac joint fusion procedure using surgical instruments specifically designed for access and treatment at a posterior inferior access region to the cartilaginous portion of the SI joint. The system allows for fewer devices implanted in the patient to reduce potential risks which are increased when having to place three or more implants. Due to the special design which resists the shear and nutational forces present at the SIJ, just a single implant can be used therefore reducing the amount of metal implanted into the patient while allowing for a great area for bone healing and bridging which provides a lasting relief to the otherwise excruciating low back, buttock and leg pain originating from the degenerative sacroiliac joint.

A surgical system includes an implant support engageable with a receiver of a fastener having a shaft fixed with vertebral tissue. A sleeve having a first mating surface releasably engageable with the implant support and a second mating surface releasably engageable with the receiver. An adaptor connected with the implant support to releasably engage a surgical instrument to distract and/or compress the vertebral tissue. Surgical instruments, constructs, implants and methods are disclosed.

A system includes an instrument and a distractor. The instrument includes a shaft extending from a first end to a second end and defining a first axis between the first end and the second end. The instrument further includes a first gear coupled to the first end of the shaft. The instrument further includes a second gear enmeshed with the first gear. The instrument further includes a reamer coupled to the second gear. Rotation of the shaft about the first axis causes rotation of the reamer about a second axis that is non-parallel with the first axis. The distractor includes a first arm defining a first passage and a second arm defining a second passage, each configured to receive a pin. The distractor further includes a retainer configured to engage the instrument to retain the instrument in position. The distance between the first passage and the second passage is adjustable.

A system for robotic spinal manipulation includes a first robotic arm comprising an end effector; a second robotic arm configured to hold a spinal rod; at least one processor; and a memory storing instructions for execution by the at least one processor. The instructions, when executed, cause the at least one processor to control the first robotic arm to link the end effector with at least one vertebral screw implanted in a vertebra of a spine of a patient; control the second robotic arm to hold the spinal rod in a predetermined pose; and cause the first robotic arm to move the at least one implanted vertebral screw into engagement with the spinal rod.

Spinal correction surgical techniques and methodologies for correction of scoliosis using non fusion anterior scoliosis correction, including soft tissue releases, unique correction techniques such as de-rotation, and unique single and dual anchor screw/cord applications.

A retractor system may provide access to a surgical site along an access pathway surrounded by tissue. In some embodiments, the retractor system may include three arms and four retractor blades, each having a tissue engagement surface. The second arm may translate along a first retraction direction relative to the first arm. The first retractor blade may be securable to the first arm and the second retractor blade may be securable to the second arm. The third arm may have a connection feature that may be removably securable to a connection interface of the second arm. The third retractor blade may be securable to the third arm and the fourth retractor blade may be securable to a rack between the first and second arms. The third and fourth retractor blades may have cross-sectional shapes oriented generally parallel to the first retraction direction.
