An interventional study of Ultrasound-guided triamcinolone injection and Ultrasound-guided PCNF-BrEpi block in Lateral Epicondylitis, sponsored by Gaziler Physical Medicine and Rehabilitation Education and Research Hospital. Recruiting at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-10-26.
Sponsored by Gaziler Physical Medicine and Rehabilitation Education and Research Hospital · Not applicable, Interventional, and Treatment
This study evaluates the effect of an ultrasound-guided posterior cutaneous nerve of the forearm epicondylar branch block on pain and functional status in patients with lateral epicondylitis. The procedure is performed using ultrasound guidance. Pain and elbow function are assessed before and after the intervention to determine whether this nerve block can improve pain and functional outcomes in patients with lateral epicondylitis.
297 studies on the registry are indexed under Tennis Elbow; 63 are open to participants now.
This study's planned enrollment of 84 is above the median of 50 across 263 interventional studies indexed under Tennis Elbow.

Exclusion Criteria:
Participants will receive conventional therapy (home exercise program and epicondylitis band) plus a single ultrasound-guided injection of 1 mL triamcinolone into the common extensor tendon origin (enthesis) at the lateral epicondyle, using an in-plane technique with a 25-gauge needle.
Drug: Ultrasound-guided triamcinolone injection · Other: Conventional therapy (home exercise program and epicondylitis band)
Participants will receive conventional therapy (home exercise program and epicondylitis band) plus a single ultrasound-guided injection of 1 mL triamcinolone into the common extensor tendon origin at the lateral epicondyle. In the same session and position, an ultrasound-guided block of the epicondylar branch of the posterior cutaneous nerve of the forearm (PCNF-BrEpi) will be performed with 1 mL of 2% lidocaine after confirming the nerve with an electrical nerve stimulator.
Drug: Ultrasound-guided triamcinolone injection · Procedure: Ultrasound-guided PCNF-BrEpi block · Other: Conventional therapy (home exercise program and epicondylitis band)
Participants will receive conventional therapy only, consisting of a standardized home exercise program (strengthening, static stretching and eccentric exercises, once daily, every day) and an epicondylitis band.
Other: Conventional therapy (home exercise program and epicondylitis band)
Single-point injection of 1 mL triamcinolone into the common extensor tendon enthesis at the most tender point of the lateral epicondyle under ultrasound guidance (in-plane technique, 25-gauge needle), with the patient supine, shoulder adducted, elbow flexed 90 degrees and wrist pronated.
Ultrasound-guided nerve block of the epicondylar branch of the posterior cutaneous nerve of the forearm with 1 mL of 2% lidocaine. Nerve localization is confirmed with an electrical nerve stimulator before injection.
Standardized home exercise program given by the same physician: manual resistance strengthening (3 sets of 10 repetitions), static stretching of the extensor carpi radialis brevis (3 x 30 seconds before and after strengthening) and eccentric wrist exercises (3 sets of 10 repetitions, progressively increased resistance), performed once daily every day, plus use of an epicondylitis band. Participants will be followed by weekly phone calls. NSAIDs are not allowed during the first month; paracetamol is permitted for pain.

Started Oct 2025 (actual). Primary completion is estimated for Dec 2026, 14 months after the start.
Of 147 non-industry interventional studies with no phase under Tennis Elbow, half reached primary completion within 8 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 24. This study's planned 14 months is above that.
Counting every sponsor, half of 150 studies reached it within 9 months; a quarter within 5 and three quarters within 22.
