Conservative management of distal bicipital tendinopathy with lateral antebrachial nerve entrapment: A case report

Introduction: Kettlebell snatches are an efficient and effective exercise. If the kettlebell being utilized is too heavy or too many repetitions are executed, this can lead to an overuse injury such as a tendinopathy. Multiple orthopedic tests exist to evaluate for a distal biceps tendon rupture. At present, there are no publications utilizing shockwave and active rehabilitation to treat distal bicipital tendinopathy with Lateral Antebrachial Cutaneous Nerve (LABCN) entrapment. Currently, no published manuscripts are reporting distal bicipital tendinopathy with LABCN nerve entrapment being treated successfully with shockwave and active rehabilitation over the course of 5 weeks.

Methods: The objective of this case report is to examine the conservative management of a 37-year-old male with a diagnosis of distal bicipital tendinopathy and LABCN entrapment. The patient presents with discomfort originated weeks prior after an intense block of kettlebell training. The patient was diagnosed with brachioradialis tendinopathy due to the specifics of his injury. Following the initial evaluation, the patient was unable to supinate the forearm past 45° actively, yet he can passively achieve 90°, although this is done with minor discomfort.

Discussion: The patient's rehab began with the execution of wrist, elbow, and shoulder controlled articular rotation (CARS). The concept of CARs is to train the joint and soft tissues to respond to full range activity. A progressive approach utilizing isometric to eccentric exercise with extracorporeal shockwave was used. The authors studied forty-eight patients with chronic distal biceps tendinopathy. After five shockwave therapy treatments over three months, there was a significant decrease in symptomology without complications (Furia et al., 2017).

Conclusion: This case report demonstrates that active rehabilitation and shockwave therapy effectively resolved the patient's symptoms with no adverse reactions. Additionally, the case report can be a suggested management protocol for successful conservative management for patients with suspected distal bicipital tendinopathy with LABCN entrapment going forward.
