Description

technical field [0001] The present disclosure relates generally to medical devices for treating spinal conditions, and more particularly to spinal implant systems including a ring that is disposable with a spinal implant to enhance fixation strength with tissue and / or to Spinal implants aid in bone on-growth. Background technique [0002] Spinal disorders and conditions such as kyphosis, scoliosis and other curvature abnormalities, degenerative disc disease, herniated discs, osteoporosis, spondylolisthesis, stenosis, tumors and fractures can be caused by factors including injury and aging trauma, disease and degenerative conditions. Spinal disorders often result in symptoms including deformation, pain, nerve damage, and partial or total loss of mobility. [0003] Non-surgical treatments such as medication, rehabilitation, and exercise can be effective, however, may not relieve symptoms associated with these conditions. Surgical treatments for these spinal conditions inclu...
