Ultrasound-Guided Distal Bicep Tendon Injection Using a Posterior Approach.

Distal biceps tendinopathy is an uncommon but increasingly diagnosed condition in persons with elbow pain. When traditional treatments are unsuccessful, practitioners have performed ultrasound (US)-guided tendon injections in this region using an anterior approach. Although success has been reported with this technique, this approach may lead to neurovascular injury. This case report is the first in the literature to describe a US-guided distal bicep tendon injection using a posterior approach. The patient had an excellent clinical outcome with no adverse events. This outcome suggests that a US-guided posterior percutaneous tendon injection might be a safe, viable, nonsurgical option for recalcitrant distal biceps tendinopathy.
