Abstract:
Objective To investigate the difficulties in posterior approach lumbar microendoscopic discectomy (MED). Methods We retrospectively analyzed records of 42 cases of lumbar disc protrusion (totally 45 interspaces) treated by MED from February 2002 to October 2003. Results Conversion to open surgery was required in 3 cases.No intra- or post- operative complications were seen.Follow-up survey for 2 ～ 22 months (mean,8 months) found the "good" or "excellent" results in 95 2% of the patients (40/42).Surgical difficulties were mainly classified into two aspects: technical and etiological,including 8 cases of failure of collimation between the passage and the interspace,5 cases of excessive bleeding disturbing the operation,3 cases of incomplete surgical apparatus,2 cases of incorrect passage localization,2 cases of hyperplasia in tiny joints,1 case of ossification of the posterior longitudinal ligament,1 case of nerve root edema,1 case of accretion,and 1 case of laceration,respectively. Conclusions Treatment of lumbar disc protrusion with MED gives satisfactory efficacy.Proper selection of patients and careful performance during surgery are essential to a successful procedure.
