OBJECTIVE: To evaluate clinical results of microscope-assisted minimally invasive decompression for degenerative @entity2649 . METHODS: From May 2007 to November 2008, 26 @entity1 with degenerative @entity2649 were treated with microscope-assisted minimally invasive decompression. Including 9 males and 17 females, the mean age were 53.7 years (range in 47-75 years). The course of disease was from 2 to 8 years with an average of 3.6 years. Single segment symptom had 20 cases and double segments had 6 cases. The clinical effects were evaluated and improvement rate was calculated according to JOA scoring before and after operation. RESULTS: The operative time in single segment was 60-90 minutes with an average of 75 minutes and in double segments was 80-180 minutes with an average of 95 minutes. The @entity548 in single segment was 50-120 ml with an average of 85 ml and in double segments was 60-150 ml with an average of 100 ml. All the @entity1 were followed up with an average of 8.6 months (range in 6-24 months). The clinical effects were evaluated according to JOA scoring,excellent in 18 cases,good in 7,poor in 1,the rate of excellent and good was 96% and improvement rate was 86%. The mean JOA scoring was respectively 3.92 +/- 0.83 and 12.67 +/- 1.92 before and after operation. There was significantly statistic difference between before and after operation (P < 0.01). CONCLUSION: Microscope-assisted minimally invasive decompression for degenerative @entity2649 can obtain satisfactory therapeutic effect,which had advantages of short operative time, less @entity130 , subtle operation, fast restoration, but it is inapplicable for the @entity1 with obviously ossification or calcification of vertebral body, severe vertebral canal adherence.
