Double-blinded randomized controlled trial with 20 people of whom 10 will receive a placebo infiltration and 10 an infiltration with botulinum toxin type A for cramping pain after arthroscopic tenotomy of the long head of the biceps tendon.
Title: Management of Popeye sign with botulinum toxin after tenotomy of the long head of the biceps tendon: a double-blinded randomized controlled trial Précis: Double-blinded randomized controlled trial with 20 people. Randomization in 2 arms of 10 people. 3 visits will be planned with a meantime of 3 months after the infiltration with botulinum toxin type A (BTX-A) or placebo that will be administered at the 2nd visit.
Objective: The primary objective is to assess the effectiveness of an infiltration with botulinum toxin in the biceps muscle after tenotomy of the long head of the biceps tendon for pain and disability reduction.
Endpoint: The primary endpoint is a pain reduction as measured by the Visual Analogue pain scale (VAS) and a reduced disability as measured by the quick DASH (Disabilities of the Arm, Shoulder and Hand).
Population: 20 people who underwent an arthroscopic tenotomy of the long head of the biceps tendon and are having post-operative pain in the biceps muscle.
