ABSTRACT
This chapter discusses various image-guided techniques including bursa, tendon/paratenon, joint and neuroma injections that are used in orthopaedics. It focuses on how to overcome common pitfalls when it comes to therapeutic injections of musculoskeletal (MSK) systems. The chapter also discusses the various image-guided techniques, focusing on USS-guided intervention, and how to overcome common pitfalls when it comes to therapeutic injections of musculoskeletal systems. Intratendinous steroid injection is associated with tendon rupture, and it is thought to be secondary to non-inflammatory degeneration of collagen at the myotendinous junction. This highlights the importance of image-guided injection of steroid: deep enough to prevent superficial lipoatrophy but not too deep as to cause intratendon injection, increasing the risk of tendon rupture and significant morbidity. The commonest type of neuroma that is encountered in MSK injection however is plantar interdigital neuroma of the foot, also known as Morton's neuroma. Informed consent, patient positioning, sterile field and needle visualisation is key to successful injection.
