DISTAL MIGRATION OF THE RODS OF A CONSTRAINED POLYAXIAL PEDICLE SCREW SYSTEM

Özet

Spinal instrumentation and surgical techniques have exponentially improved over the years, and today’s spinal surgeon is well equipped to rigidly fix the spine with minimum adverse effects. Complications may emerge during or after the surgical operations. Infection, hematoma and neurological deficits are early noticed findings. Instrumentation problems i.e. screw and/or rod failures present in long-term after surgery. Caudal rod migration out of the spinal column is a rare entity. We report here three case incidents (in two patients) of lumbar degenerative disorders requiring spinal instrumentation that represented with caudal rod migration, all associated with one particular implant made.
