Application of epoxy resin to a solid-foam pelvic model: creating a dry-erase pelvis

The value of preoperative planning and templating has been well-established in fracture surgery. We have found that using 3-dimensional (3-D) models in preoperative planning aids in the understanding of anatomy, fracture-reduction techniques, and fixation methods, particularly in pelvic and acetabular fractures. To facilitate the correction of errors and reuse for future cases, we coat pelvic models with dry-erase epoxy resin. Fracture lines and planned implants are drawn onto the models with dry-erase markers. The creation of 3-D planning tools is useful in understanding the anatomy of pelvic and acetabular fractures.
