Objective: To develop a simulator for training in facet joint injections guided by fluoroscopy and evaluate the learning curve in this procedure in a group of radiology residents. Materials and Methods: Using a human lumbar spine as a model, we developed 5 lumbar vertebrae using methacrylate and plaster. These vertebrae were combined to form a spine model. We used a silicon envelopment to emulate the paravertebral muscles. The spine model was placed in the trunk of a plastic mannequin. We recruited 12 volunteers among radiology residents in our department. Each of these students performed 16 lumbar facet injections in our simulator during a training session. We used 3 parameters to assess the learning curves: procedure time, fluoroscopy time and quality of the procedure, defined according to the correct orincorrect positioning of the needle. Results: The learning curves of all the students showed improvement in procedure and fluoroscopy time parameters during the training. The quality of the procedure parameter also showed improvement, defined by a decrease in the number of incorrect injections. Conclusion: We present a simulation model for training in facet joint injections. The learning curves of our trainees using the simulator showed improvement in all assessed parameters.
