Intra-articular injections are routinely performed to alleviate pain and inflammation associated with osteoarthritis in horses. Intra-articular injections require accurate needle placement to optimize clinical outcomes and minimize complications. This study’s objectives were to develop and validate a three-dimensional (3D) printed model of an equine cervical articular process joint to teach ultrasound-guided injections. Five identical models of an equine cervical articular process joint were 3D printed and embedded in 10% ballistic gelatin. Experts’ and novices’ ability to successfully insert a needle into the joint space of the model using ultrasound guidance was assessed and graded using an objective structured clinical examination (OSCE). Scores from experts and novices were compared to evaluate the construct validity of the model. Participants also answered a survey assessing the face and content validity of the model. Experts required less time (22.51 seconds) for correct needle placement into the model joint space than novices (35.96 seconds); however, this difference was not significant ( p = .53). Experts’ median total OSCE score (14) was significantly higher ( p = .03) than novices’ (12), supporting the model’s construct validity. Participants agreed on the face and content validity of the model by grading all survey questions greater than 7 on a 10-point Likert-type scale. In summary, we successfully developed a 3D printed model of an equine cervical articular process joint, partially demonstrated the construct validity of the model, and proved the face and content validity of this new training tool.

The landmark paper discussed in this chapter is ‘Endosonography-guided celiac plexus neurolysis’, published by Wiersema and Wiersema in 1996. Pain is one of its most distressing complaints of pancreatic cancer, affecting more than 80% of patients with advanced disease. However, the use of opioids and other drugs is often limited by undesirable side effects, which include somnolence, confusion, lethargy, and decreased cognitive function. Intrathecal drug delivery systems, although effective, are often deemed impractical in pancreatic cancer, due to its poor prognosis and the fact that it is often diagnosed late. Tumour infiltration of the coeliac plexus results in pain in the abdomen and back; thus, this area has often been targeted for analgesia via a neurolytic coeliac plexus block. The paper by Wiersema and Wiersema examines the efficacy of an approach that uses ultrasound to guide needle placement in celiac plexus neurolysis, in a study of 30 patients.
