Abstract

Purpose: Percutaneous intervertebral disc puncture is useful in various situations. The isocenter puncture method enables easy, accurate, and safe punctures under fluoroscopic guidance. Herein, we present a clinical application of this technique that improves upon percutaneous puncture of intervertebral discs.

Material and methods: We performed percutaneous punctures of intervertebral discs slightly lateral to the superior articular process using the isocenter puncture method in 19 cases (10 men, 9 women; mean age, 64.5 years; range, 23-87 years). We assessed the technical success rate, procedure time, and complications.

Results: We achieved successful punctures in all cases, with a median puncture time of 14.5 min (mean, 18.7 ± 11.3 min; range, 8-49 min). No patients complained of complications that were permanent or required treatment.

Conclusions: Improved puncture of intervertebral discs seems to be possible using the isocenter puncture method.
