摘要：
Spinal implant trials are provided having various configurations and sizes that aid the selection of spinal implants having similar configurations and sizes. A surgeon during surgery can insert various configurations and sizes of the spinal implant trials into a disc space between two adjacent vertebral bodies of a patient to enable the selection of a spinal implant configured and sized to fit the patient's disc space. Fluoroscopic images can be used in aiding the selection of an appropriately configured and sized spinal implant corresponding to one of the spinal implant trials. The spinal implant trials include features that reveal on the fluoroscopic images whether the spinal implant trials are properly located and oriented in the disc space and include features corresponding to different sizes of spinal implants also revealed on the fluoroscopic images.
