Abstract:
[Objective]To investigate the diagnostic methods and clinical effects of the management of spondylolithesis with adjacent segment degeneration.[Method]Between October 2000 and October 2005,16 consecutive patients(3 males and 13 females) aging 42 to 76 years(mean 59.1 years) received instrumented lumbar interbody fusion procedure using traditional posterior approaches for spondylolithesis with adjacent segment degeneration.Lumbar functions were assessed using Prolo system.Preoperative and follow-up lateral lumbar radiographs were studied for reduction of spondylolithesis,disc heights,lumbar lordosis,fusion rates and complications.[Result]Fourteen patients were followed up,with an average duration of 28(16–53) months.Clinical outcomes in terms of Prolo system was 7 points in 3 patients,8 in 7 patients,9 in 2 patients,and 4 in 2 patients at 3 months after operation with 85.7% being graded as good or excellent.Seven points in 4 patients,8 in 6 patients,and 9 in 4 patients at last follow-up(graded as 100% good or excellent).Fusion rate was 66.7%(8/14)at 6 months and 92.9%(13/14)at 12 months after operation.Ten patients(71.4%) fully recovered from spondylolithesis,4 had partial reduction,and their reduction status was unchanged according to plain radiographs at 12 months and last follow-up.The operative wound healed without complications in all patients.The mean Lordosis was 26.64??6.67?,33.29??3.39?and 32.71??2.80?before and at 3-month,or last follow-up after operation.The mean of fused Lordosis was 15.64??6.21?,28.29??3.28?and 32.36??3.91?before at 6 months or at last time follow-up after operation.The disc heights were 6.54?1.13mm and 9.62?0.81mm before and after operation.Statistics showed significant difference(P
