Abstract:
Objective To observe the clinical therapeutic outcomes and the radiographs changes of lumbar degeneration disease treated by dynamic stabilization device (Wallis). Methods Eighty-four cases of lumbar degeneration disease were treated by threaded fusion cage, from May 1997 to May 2002. The JOA scores, the rate of fusion,cage sink and adjacent segment degeneration were observed. Results The average hospitalizotion was 23.59 days. The mean operation time was 3.00 hours. The mean JOA scores were 13.93 before the operation,while 26.69 on the end of the following time respectively; there was statistical significant. The mean motion of operative segment was 5.22 before operation, while 2.44 on the end of the following time respectively. The mean extension of operative segment was 3.32 before operation ,while 1.39 on the end of the following time respectively. The mean motion of adjacent segment was 3.68 before operation, while 6.54 on the end of the following time respectively. The mean extension of adjacent segment was 1.95 before operation,while 3.95 on the end of the following time respectively. There were all statistical significant on those changes of Cobbs angel. Conclusions The long-term therapeuptic effect of WALLIS treatment for lumbar degeneration disease is reliable. The motion of operative segment was significant decreased, especially on extension. The motion of adjacent segment was significant increased, the degree extension of adjacent segment was also significant increased.
