Abstract

Thoracic/lumbar and cervical spinous process staples which staple/fuse adjacent spinous processes are disclosed. Thoracic/lumbar transverse process staples which staple/fuse adjacent transverse processes are also disclosed. Each embodiment has upper and lower claws connected by a ratchet spring mechanism, along with a multiplicity of bone fastener prongs attached to the upper and lower claws. Two sets of prongs on each staple claw are spaced by a distance approximately equal to the distance separating adjacent spinous or transverse processes so as to facilitate stapling/fusion of two adjacent processes. Also disclosed are staple prongs with multiple perforations which enable incorporation of bone fusion material thereby facilitating stapling/fusion of spinal elements.
