				        	[Objective]To evaluate short term clinic results of prosthetic disc nucleus(PDN)replacement for the treatment of lumbar disc herniation.[Method]Twenty cases of lumbar disc herniation(including one case of recurrent lumbar disc herniation)were treated with PDN from June 2003 to November 2003,including 13 males and 7 females with average age of 40.5 years.All cases were implanted with a single PDN,in which 7 cases with PR725,8 cases with PW725,and 5 cases with PDN-SOLO-7 respectively.[Result]After surgery,one patient accepted the revision operation to remove the PDN because of device migration,the others experienced pain relief.The nineteen cases were followed-up for 23~29 months(mean 26.4 months).Compared with preoperative height of intervertebral disc,it gained increase of 17.2%(P
