A spinal implant for repairing a region of a subject's spine may have a
plurality of interlockable segments that can be deployed from a delivery
configuration (e.g., a linear array) into a deployed configuration. When
the implant is in the delivery configuration, the implant comprises a
linear array of the segments that are flexibly connected, and when the
implant is in the deployed configuration, the segments are interlocked
into a stable structure so that each segment is adjacent to and
interlocked with at least two other segments. in the deployed
configuration, the implants may have a greater strength (e.g., crush
strength) and may help maintain the stability of the body region. The
implant may be inserted into the spinal region by an applicator from the
posterior region of the subject in the delivery configuration and
assembled within the body to form the deployed configuration.
