Aims and objectives
Lateral elbow tendinopathy,
also referred to as tennis elbow has been described extensively in medical literature. It affects the common extensor tendon,
most commonly occurring within the extensor carpi radialis brevis.
Although it may have a self-limiting course,
the relative morbidity in the economically active population has resulted in a variety of non-conservative therapies.
Invasive treatments such as surgery,
injection with steroids and platelet-rich plasma have been used in the management of refractory cases.
There is no histological evidence of acute inflammatory cells within the tendon; however,
mucoid degeneration with disrupted collagen fibres and neovascularisation have been documented(1).
Ultrasound imaging has shown diffuse tendon thickening,
hypoechoic segments,
calcification,
partial or full thickness tears and raised vascularity.
As part of an open-label study(2) performed at our institution to evaluate the efficacy and safety of a novel ultrasound-guided percutaneous tenotomy for tennis elbow,
diagnostic ultrasound studies were performed.
The purpose of this study was to evaluate the sonographic appearance of the common extensor tendon in symptomatic tennis elbow patients and resolution of observed features following therapeutic treatment.
