Imaging diagnosis of the acute Achilles tendon rupture

Objective To evaluate the diagnostic value of Achilles tendon rupture by using X-ray plain films and MR images. Methods The plain films and MRI findings in 21 patients with operation proved acute Achilles tendon rupture were analyzed, and every manifestation on MR and operation were compared.Results The Achilles tendon rupture was diagnosed on MRI in all 21 cases. Complete rupture of Achilles tendon was showed in 7 and partial rupture in 14. MRI appearance of the rupture represented as thickening of Achilles tendon, hyperintensity in the tendon, and completely or partly discontinuance of the fibrous bundle. X-ray showed Achilles tendon rupture in 5, suspicious rupture in 12, and normal in 4. Operation showed Achilles tendon complete rupture in 9 and partial rupture in 12.Conclusion MRI can accurately show the degree and location of acute Achilles tendon rupture, which is very helpful for treatment. X-ray is the adminicular method in detecting Achilles tendon rupture and the diagnosis should be depended on MRI to confirm the the acute Achilles tendon rupture.
