Objectives
We assessed the implications of MR imaging with clinical history in lateral epicondylitis management by evaluating imaging and clinical features in patients with lateral epicondylitis treated conservatively or operatively.
Methods
Sixty patients with lateral epicondylitis treated conservatively (n = 38) or operatively (n = 22) from 2011–2015 were included. MR imaging findings of common extensor tendon (CET), lateral collateral ligament (LCL) complex, muscle oedema, ulnar nerve and elbow joint were reviewed. Clinical data recorded were frequency, duration and intensity of pain, history of trauma and injection therapy, range of motion.
Results
MRI-assessed CET and LCL complex abnormalities, muscle oedema, radiocapitellar joint widening, joint effusion/synovitis, pain frequency and intensity differed significantly between the two groups (p < .05) with increased severity in operative group. Persistent pain (OR 12.2, p < .01), CET abnormality on longitudinal plane (OR 7.5, p = .03 for grade 2; OR 22.4, p < .01 for grade 3) and muscle oedema (OR 6.7, p = .03) were major factors associated with operative treatment. Area under the ROC curve of predicted probabilities for combination of these factors was 0.83.
Conclusion
MR imaging, combined with clinical assessment, could facilitate appropriate management planning for patients with lateral epicondylitis.
Key Points
• MRI can reflect different disease severity between patients treated conservatively/operatively.
• CET abnormality, muscle oedema were major MRI findings with operative treatment.
• Patients in operative group were more likely to experience persistent pain.
• MRI plus clinical symptoms could facilitate appropriate management for lateral epicondylitis.
