Cauda equina syndrome is a fairly rare complication that can occur after lumbar disc prosthesis surgery. A 28-year-old male received surgery for lumbar disc hernia, and was given posterior lumbar disc prosthesis by a microsurgical method. He was admitted to hospital one month later with cauda equina syndrome caused by posterior migration of the lumbar disc prosthesis and compression of the spinal cord. The prosthesis was surgically removed. Here, the indications and complications of lumbar disc prosthesis are discussed, considering the literature. This case is reported due to its rarity.
