Ligament-sparing lumbar microdiscectomy. Results of clinical application of a technique
Keywords:
disc herniation, microdiscectomy, epidural fibrosis, yellow ligamentAbstract
There were 136 sequential patients operated on for the analysis of efficiency of ligament-sparing lumbar microdiscectomy. The operation was executed on LIV—LV, LV—SI levels. For 112 patients in an access time to a hernia of the disc was executed lateral flavectomy or flavotomy, for 24 patients anatomical features demanded fulfilment total flavectomy, interlaminectomy. Distinguished following methods of flavectomy.
The long-term follow-up for 112 patients, where used lateral flavectomy or аlavotomy, oscillated from 13,5 about 1,5 months. Among these patients there were no complaints to radicular pains, the recovery of mobility of an operated segment was marked earlier. Recovery of capacity for work also is marked earlier. For no one of these patients in the postoperative term the assigning of steroids or nonsteroidal anti-inflammatory drugs was not required. Formation of postoperative hematomas never was marked.
The technique of ligament-sparing lumbar microdiscectomy is a perspective new method, which one helps to minimize a surgical trauma, to increase outcomes of treatment patients with hernias of lumbar intervertebral discs. One of the relevant advantages of this method is the avoidance of formation peridural fibrosis.
