Abstract:
ObjectiveTo Compare the clinical results between microscope and loupes which used in microsurgical discectomy.MethodsA prospective randomized controlled trial of 93 patients who had undergone microsurgical discectomy from January 2007 to December 2010 was performed.Clinical results were assessed by comparing the following parameters between patients who had undergone the surgery by microscope and loupes:length of stay,hospitalization cost,operative time,estimated blood loss,Japanese Orthopaedic Association (JOA) score and JOA recovery rate,Odom's standard.ResultsForty-nine patients underwent surgery by microscope,and forty-four patients underwent surgery by loupes.Eighty patients received outpatient or telephone follow-up.The follow-up period was 6.17 to 52.90 months with an average of (29.64±13.05) months,and the follow-up rate was 86.02％.According preoperative data,the two groups didn't differ with respect to age,gender,level of radiculopathy,or preoperative JOA score and JOA recovery rate.No statistically significant differences were identified in postoperative JOA score and JOA recovery rate,length of stay,hospitalization cost,length of follow-up,or relapse rate.Statistically significant differences were identified in operative time,estimated blood loss,and follow-up JOA score and JOA recovery rate.Conclusion Microscope can provide relatively more clear and comfortable vision for the surgery.It can short the operative time,decrease blood loss,reduce the potential risk of nerve injury,and retain more normal tissue,which can ensure better clinical results.
