Embodiment Construction

[0014] The expandable interbody implant systems disclosed herein are discussed in terms of medical devices for treating musculoskeletal disorders, and more particularly in terms of expandable interbody implant systems and related methods for treating the spine and exemplary embodiments of related methods of use. It is envisioned that the implant system can provide, for example, fusion, decompression, restoration of sagittal plane balance, and resistance to subsidence into tissue, such as the surface of a vertebral endplate.

[0015] In some embodiments, the expandable intervertebral implants of the systems disclosed herein are used to achieve implant geometries that would otherwise be impossible or difficult to insert with minimal morbidity. Expandable interbody implants allow expansion in two ways. One part increases the overall height of the implant (parallel expansion), while the other part manipulates the angle of the implant while the one part increases the overall heigh...

Abstract

A device includes a core having proximal and distal ends and defining a first female thread. A drive screw includes first and second ends. The first end includes a first male thread. The second end includes a second male thread that engages the first female thread. A first body includes a second female thread that engages the first male thread. A second body is coupled to the drive screw. A first plate is coupled to the core and the first body. The first plate includes a first vertebral engaging surface. A second plate is coupled to the core and includes a second vertebral engaging surface. The drive screw is configured to rotate relative to the core to simultaneously pivot the first plate relative to the core and alter a distance between the first vertebral engaging surface and the second vertebral engaging surface.

Description

technical field [0001] The present disclosure relates generally to medical devices, systems and methods for treating musculoskeletal disorders, and more particularly to expandable interbody implant systems and methods for treating the spine. Background technique [0002] Spinal conditions such as degenerative disc disease, herniated discs, osteoporosis, spondylolisthesis, stenosis, scoliosis and other curvature abnormalities, kyphosis, tumors and fractures may be caused by including trauma, disease and by injury and aging Factors causing degenerative conditions. Spinal disorders often result in symptoms including pain, nerve damage and partial or complete loss of mobility. For example, after a disc collapse, severe pain and discomfort can occur due to the pressure placed on the nerves and spine. [0003] Nonsurgical treatments such as medication, rehabilitation, and exercise may be effective, however, may not relieve symptoms associated with these conditions. Surgical tre...
