Background
Procedural phantoms can be valuable aids in radiology resident education, providing a low-risk means of instruction, practice, and assessment. Simulation-based learning can offer safe opportunities for troubleshooting and repetition, increase trainee and patient comfort, and accelerate mastery of procedural competencies. However, commercially available phantoms of relatively complex structures, such as diarthrodial joints, are generally expensive, ranging from 1000 dollars to 4000 dollars. Some previously described methods of constructing joint phantoms are technically complex and time consuming. The purpose of this educational exhibit is to describe simple methodology for making effective joint phantoms from inexpensive materials, to allow simulation of positioning a needle into the joint under fluoroscopic or ultrasound guidance.

Educational Goals / Teaching Points
The teaching points of this exhibit include the following: first, to discuss the potential benefits of phantoms in developing simulation-based curricula for fluoroscopy- and ultrasound-guided joint injections; second, to describe simple methodology of making inexpensive and life-like joint phantoms; and third, to describe the uses of these joint phantoms in radiology resident instruction and assessment.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
1.) Potential benefits of simulation-based curricula in teaching fluoroscopy- and ultrasound-guided joint injections. 2.) Equipment and resources necessary to make joint phantoms. 3.) Designing joint phantoms with material properties of living tissues, including variable tissue density and elasticity. 4.) Overcoming challenges of embedding multiple desiccated bone samples in ballistic gel. 5.) Applications of joint phantoms in radiology trainee education.

Conclusion
Simulation-based learning incorporating joint phantoms can facilitate radiology resident mastery of procedural competencies, such as fluoroscopy- and ultrasound-guided joint injections. Joint phantoms can be made relatively simply and inexpensively to simulate correct needle placement during image-guided joint injections.
