Abstract:
[Objective]To explore the clinic results of bi-posterolateral fusion combined with coralline hydroxyapatite interbody fusion,a three point stable spine fusion technique in the treatment of degenerative vertebra disc disorder.[Method]Bi-posterolateral fusion combined with posterior interbody fusion were performed to treat 41 cases of degenerative vertebra disc disorder from August 1998 to August 2006.The patients included 18 men and 23 women;their average age was 48 years.The slippage and grade of spondylolisthesis before and after spine fusion were investigated.The severity and slippage of radiographic measurements were also recorded,along with the average follow up of 19.1 month(range 12-48 months).The three point spine fusion applied autologous bone chips for bi-posterolateral fusion and one cubic block of coralline hydroxyapatite for anterior inter body fusion which achieved by PLIF technique.[Result]In the 41 patients who had underwent three point spine fusion surgery,only 1/41 patients experienced nerve root pain after surgery,and in most cases clinical symptoms were improved greatly.In 21/41 patients who had severe lower back pain completely disappeared after surgery,and in 9/41 cases these symptoms were minimal.The clinical evaluation according to the symptoms before the operation was excellent 2.4%(1/41),good 19.5%(8/41),fair 21.9%(9/41),bad 56.1%(23/41);after operation excellent 68.3%(28/41),good 29.2%(12/41),fair 2.4%(1/41),bad 0.0%(0/41).A radiographic measurements showed the anterior disc height was 8.05?2.35mm before operation and 11.44?3.38mm after operation(P
