MRI Evaluation of Achilles Tendon Injuries

Introduction : Although it is the strongest tendon in the human body, the Achilles tendon is the most commonly injured ankle tendon. Clinical evaluation alone is often suggestive of the diagnosis of acute rupture of the Achilles tendon, which could be partial or complete. However, the clinical examination alone is not sufficient in all cases, and imaging can play a crucial role. Aim of the Work : The purpose of this study was to evaluate the role of MRI in differentiating full-thickness tears from partial-thickness tears or tendinosis of the Achilles tendon. Material and Methods: 14 patients with clinically suspected tear of the Achilles tendon underwent MRI evaluation after proper clinical evaluation. Results: MRI findings were suggestive of full thickness tear in 8 patients, who were operated, and of partial thickness tear in 6 patients who were treated conservatively by cast. Two of these 6 patients were operated later after failure of the conservative treatment while the other 4 patients improved upon conservative treatment. Conclusion : MRI is a sensitive and accurate tool for evaluation of the spectrum of abnormalities encountered with Achilles tendon injury, with good ability to discriminated partial from full thickness tears.
