The Surgical Treatment of the Sequested Lumbar Disc Herniation

Objective To evaluate the clinical efficacy of neucleus extraction for the sequested lumbar disc herniation.Methods 58 patients with sequested lumber disc herniation were treated surgically between Jan.2003-Dec.2009.There were 31 males and 27 females with average age of 38.5 years(range from19 to 54 years).L3～4were involved in 3 cases,L4～5in 29 cases,L5S1in 26 cases.The patients were treated by window-open,semi-laminectomy,complete laminectomy respectively based on site of herniation.The duration,symptoms and signs,the radiology performance and the operation treatment result were discussed.Results All the patients were followed-up for an average of 3.5 years(range 1 to 6 years).The surgery time was(1.0±0.2) hours and the bleeding was(280±25) mL.Complications included cerebrospinal fluid leakage in 6 cases,unilateral transient lower extremity paresthesia in 2 cases.According to Nakai Criterion,the result for the operative treatment was excellent in 24cases,good in 27 cases,fair in 5 cases,poor in 2 cases.The rate of excellent and good results was 87.9%.Conclusion The sequested neucleus extracted completely is a good method for the sequested lumbar disc herniation.
