TECHNICAL FIELD

The present disclosure generally relates to medical devices for the treatment of musculoskeletal disorders, and more particularly to a surgical system and a method for treating a spine.

BACKGROUND

Spinal pathologies and disorders such as scoliosis and other curvature abnormalities, kyphosis, degenerative disc disease, disc herniation, osteoporosis, spondylolisthesis, stenosis, tumor, and fracture may result from factors including trauma, disease and degenerative conditions caused by injury and aging. Spinal disorders typically result in symptoms including deformity, pain, nerve damage, and partial or complete loss of mobility.

Non-surgical treatments, such as medication, rehabilitation and exercise can be effective, however, may fail to relieve the symptoms associated with these disorders. Surgical treatment of these spinal disorders includes fusion, fixation, correction, discectomy, laminectomy, corpectomy and implantable prosthetics. As part of these surgical treatments, spinal constructs, for example, bone fasteners, spinal rods and interbody devices can be used to provide stability to a treated region. For example, during surgical treatment, surgical instruments can be used to deliver components of the spinal constructs to the surgical site for fixation with bone to immobilize a joint. Surgical retractors may be employed during a surgical treatment to provide access and visualization of a surgical site. Such retractors space apart and support tissue and/or other anatomical structures to expose anatomical structures adjacent the surgical site and/or provide a surgical pathway to the surgical site. This disclosure describes an improvement over these prior technologies.

SUMMARY

In one embodiment, a surgical instrument is provided. The surgical instrument includes at least one blade defining a longitudinal axis and including a distal member. An actuator is engageable with the member to rotate the member relative to the longitudinal axis to space tissue adjacent a surgical site. In some embodiments, surgical systems, constructs, implants, and methods are disclosed.

In one embodiment, the surgical instrument includes at least one blade defining a longitudinal axis and including a distal member. An actuator includes a linkage and is engageable with the member to rotate the member relative to the longitudinal axis between a first orientation and a second orientation to space tissue adjacent a surgical site.

In one embodiment, the surgical instrument includes at least one blade defining a longitudinal axis and including a distal member. An actuator includes a threaded shaft and is engageable with the member to fix the member in a selected orientation relative to the longitudinal axis to space tissue adjacent a surgical site.
