Microdecompression for intraforaminal lumbar disc herniations

Objective: To summarize clinical results of the microdecompression for the treatment of intraforaminal lumbar disc herniations. Methods: From September 2005 to May 2013,16 patients(12 males,4 females)with intraforaminal lumbar disc herniations underwent microdecompression,ranging in age from 32 to 56 years old with a mean of 38.6 years old. The lumbar disc herniations were located at L_3,4 in one patient,L_4,5 in 10 cases and L₅S₁ in 5 cases. Results: All the patients were followed up,and the duration ranged from 20 to 48 months,with a mean period of 36 months. According to Macnab evaluation,12 cases got an excellent result,4 good. No apparent complications related to the technique occurred. Satisfactory clinical results were obtained in this series. Conclusion: Microdecompression may be particularly useful in the treatment of intraforaminal lumbar disc herniations. The microdecompression procedures are more likely to be well tolerated by older patients.
