Abstract

PURPOSE:

Facet syndrome is a condition that may cause 15-45 % of chronic lower back pain. It is commonly diagnosed and treated using facet joint injections. This needle technique demands high accuracy, and ultrasound (US) is a potentially useful modality to guide the needle. US-guided injections, however, require physicians to interpret 2-D sonographic images while simultaneously manipulating an US probe and needle. Therefore, US-guidance for facet joint injections needs advanced training methodologies that will equip physicians with the requisite skills.

METHODS:

We used Perk Tutor-an augmented reality training system for US-guided needle insertions-in a configuration for percutaneous procedures of the lumbar spine. In a pilot study of 26 pre-medical undergraduate students, we evaluated the efficacy of Perk Tutor training compared to traditional training.

RESULTS:

The Perk Tutor Trained group, which had access to Perk Tutor during training, had a mean success rate of 61.5 %, while the Control group, which received traditional training, had a mean success rate of 38.5 % ([Formula: see text]). No significant differences in procedure times or needle path lengths were observed between the two groups.

CONCLUSIONS:

The results of this pilot study suggest that Perk Tutor provides an improved training environment for US-guided facet joint injections on a synthetic model.
