INTERVERTEBRAL DISC REPLACEMENT TRIAL

摘要

An intervertebral disc replacement trial (1200) includes a shaft (1202) having a handle at a proximal end (1206), and a head (1208) disposed at a distal end (1204) of the shaft. The head includes first and second surfaces (1210, 1212) that are spaced apart and sized for insertion into at least one intervertebral disc space defined by respective endplates of an adjacent pair of vertebral bones of a spinal column. The trial facilitates distraction of the vertebral bones in a direction along a longitudinal axis of the spinal column.
