Abstract Objective The authors propose the analysis of quantitative and qualitative learning curves of transpedicular puncture in a manikin-type training simulator model for transpedicular puncture (SMTP) Methods Six students (S1 to S6) were selected to perform the puncture training under radiological control. Quantitative parameters such as the procedure time (total time spent in performing each procedure) and fluoroscopy time (fluoroscopy usage time for each punch) were analyzed using the Mann-Whitney test. For the qualitative evaluation, the punctures were categorized into type AB (adequate) or CD (inadequate) according to the path and positioning of the needle. Qualitative data were analyzed by Fisher's exact test. Results The curves of the examination times and fluoroscopy decreased steadily as expected, especially for the trainee S3. In addition, there was a predominance of punctures AB of the third subsequent session

however, this result was statistically significant for the S1 and S2 trainees. Conclusion The learning curves indicate that qualitative performance improves as students become more familiar with the process.
