ALTHOUGH the technique and the roentgen findings in lumbar disk puncture are reported in the literature, their clinical value has been stressed only briefly, and further clinical studies of this new diagnostic method are needed. In the following article 67 cases, with 98 disks examined, are analyzed, and a clinical review is given.
Lumbar disk puncture was introduced by Lindblom.1 We have used the original method, with the following modification. Instead of introducing the needle under fluoroscopic control, the posterior arch of the vertebra has been localized by the bone contact obtained with the needle, which has to be introduced just below the arch. An exposure of the roentgenologist's hands to the rays and a time-consuming adaptation of the eyes are thus avoided. The modified technique is described in the following paragraph.The patient is in a prone position, with pads under his abdomen to reduce the lordosis.
