A prospective study has found that transcatheter arterial embolisation (TAE) is a safe and effective treatment option for lateral epicondylitis which is resistant to conservative treatment.
A Japanese study was conducted including 52 patients with lateral epicondylitis that is resistant to conservative treatments for more than three months, with a symptom duration longer than six months and with moderate to severe pain, who were treated with TAE between March 2013 and October 2017.
Forty-eight patients were followed-up for up to four years after TAE. Quick Disability of the Arm, Shoulder and Hand scores significantly decreased from baseline at one, three, six, and 24 months post-treatment (52.1 vs 21.4, 8.2, 5.6 and 3.7, respectively; all P<.001>
There was a statistically significant change from baseline to the last observed value in all of the clinical parameters (P<.001>
MRI obtained two years after TAE (n=32) showed an improvement in tendinosis and tear scores compared with baseline, and no patients showed bone marrow necrosis, obvious cartilage loss or muscle atrophy.
The authors concluded that TAE could be a treatment option for lateral epicondylitis patients who fail to improve with conservative treatments.
The research was presented at the American Society of Interventional Radiology annual meeting in Texas, USA, earlier this week.
