Clinical Study Of Different Surgical Procedures For The Treatment Of Lumbar Spondylolisthesis: Clinical Analysis On 82 Cases

Purpose Through the analysis of 82 cases of spondylolisthesis treated with surgery, the different types of surgical procedures were evaluated.Material and Method Patients with spondylolisthesis were divided into 4 groups based on their pathology and different surgical procedures were used accordingly. Group â…  consisted of 18 patients with degenerative spondylolisthesis with back pain(3 cases) and isthmic spondylolisthesis( 13 cases) and traumatic spondylolisthesis(2 cases) of â…  degree; They were treated with posterior interlaminar and interspinous process fusion ; Group â…¡ consisted of 31 cases with degenerative spondylolisthesis(2 cases) and isthmic spondylolisthesis(23 patients) and traumatic spondylolisthesis (6 cases)of â…  degree(ll cases) and â…¡ degree(20 cases); They were treated with reduction of sliding vertebra and posterior interlaminar and interspinous process fusion ; Group â…¢ consisted of 19 cases with degenerative spondylolisthesis(2 cases) and isthmic spondylolisthesis(17 cases) of â…  degree(2 cases) , â…¡ degree(13 cases) and â…¢ degree(4 cases);They were treated with laminectomy and decompression, with reduction of sliding vertebra and transverse process fusion ;Group â…£ consisted of 14 cases with isthmic spondylolisthesis of â…  degree(l cases) , â…¡ degree(10 cases) and â…¢ degree(3 cases); They were treated with laminectomy and decompression, with intervertebral body fusion, with reduction of sliding vertebra and transverse process fusion.Result In group I,solid fusion was in 15 cases giving a fusion rate of 83%,0.03% rate of reduction, 52.69% rate of improvement; In group â…¡,solid fusion was in 30 cases giving a fusion rate of 96%,56.20% rate of improvement, 83% rate of reduction; In group â…¢, fusion rate and reduction rate and improvement rate reached 89%, 90% , 59.85% respectively; In group IV, the fusion rate and reduction rate and improvement rate was as high as 100% , 92% , 61.08% respectively.Conclusion Operative methods differ from different patients. Reduction(part reduction) , effective decompression and fusion is treatmentive principle.
