Percutaneous lumbar medial branch neurotomy: a modification of facet denervation.
Percutaneous lumbar medial branch neurotomy is a technique for facet denervation in which the target is specifically the medial branch of the dorsal ramus. The radiology of the technique is illustrated, and the technical aspects of the procedure are described. The accuracy of previous techniques for facet denervation as compared with medial branch neurotomy is reviewed in a comparative analysis of radiographs illustrating the various techniques. It is suggested that the greater accuracy of medial branch neurotomy will permit a more adequate trial of the rationale and efficacy of facet denervation.
