Abstract
Background: The AT is the largest tendon in the body; it plays an important role in the biomechanics of the lower extremity; despite its strength, the AT is also vulnerable to injury, due to its limited blood supply from musculotendinousa, also it withstands great forces, especially during sporting exercises and it’s located superficially.
Aim of the Work: To evaluate the role of (MRI) in the diagnosis of AT disorders.
Patients and Methods: Type of Study: retrospective and prospective studies. Study Setting: The study was conducted in Radiology Department at Ain Shams University Hospitals. Study Period: from march 2018 to march 2020. Study Population: This study included 40 patients. The patients were referred from either the orthopedic, rheumatology outpatient clinics of Ain Shams hospitals or private clinics to radiology department in Ain Shams University.
Results: Full thickness tear (30.0%) and Tendenosis (30.0%) were the most frequently detected pathologies followed by partial thickness tear (27.5%) and bursitis ( 22.5%) with significant more risk in male gender and middle age ( >46 years). More than one pathology were found in the same MRI study and this led to development of degenerative theory, that consider almost ruptured AT develop on top of pathological one.
Conclusion: MRI is a gold standard and important diagnostic tool in the evaluation of AT lesions especially in chronic and complex cases, and who do not respond to conservative measures and provides precious information for surgical intervention in parallel with careful clinical examination. Full thickness tear and partial thickness tear may develop on top of pathological tendon.
