Ultrasonographic Examination of Other Enthesitis Sites in Patients With Lateral Epicondylitis

Ultrasonographic Examination of Other Enthesitis Sites in Patients With Lateral Epicondylitis: A Cross-Sectional Study

Lateral epicondylitis (LE) is the tendinopathy of the common extensor tendon. Although exact etiology remains unclear, it is believed to be caused by overuse.

Even though, genetics factor related to tendinopathies were defined accompanying tendinopathies in patients with LE is yet to be studied.

Madrid sonographic enthesitis index (MASEI) is an ultrasound based scoring system, developed for the evaluation of the enthesitis. Initially developed for ankylosing spondylitis, its usage has also become widespread in other musculoskeletal diseases.

The aim of this study is to calculate the MASEI score in patients diagnosed with LE, and compare it to healthy volunteers.

Inclusion Criteria:

• Tenderness with palpation at the lateral epicondyle
• Pain aggravated with resisted wrist extension

Exclusion Criteria:

• History of rheumatologic diseases
• History of elbow, knee or ankle surgery
• History of corticosteroid injections on elbow, knee or ankle
• History of peripheral neuropathy
• Acute trauma
