ABSTRACT

[Objective]To study the clinical characteristics of osteochondrosis of lumbar posterior vertebral edge(OLPV) and evaluate the efficiency of surgical treatment. [Method]From August 2000 to August 2003,41 cases of OLPV patients were treated,all cases underwent decompression of posterior approach and selective resection of the compressive things.Furthermore,1 case was treated with trans-vertebral pedicle internal fixation and inter-transverse process bone graft because of excessive decompression and preoperative lumbar instability.[Result]Low back and leg pain disappeared or obviously being relieved in all cases,and the results of histological analysis suggested the diagnosis of OLPV in all cases.Forty-one cases were followed from 5 to 8 years,average 6.8 years.No lumbar instability or spondylolisthesis was found in any case.Six cases suffered slight low back pain occasionally without obvious impaired quality of life.The preoperative JOA score was 14.73?2.06,when followed by 3 months,the score changed into 27.14?4.13,there was statistical significance between them(P
