Abstract:
Background Ankle and foot pain is a common clinical problem, that may be due to a variety of soft tissue and osseus abnormalities. Magnetic resonance imaging plays vital role for diagnosing internal derangement of the ankle joint, assessing soft tissue structures around the ankle such as tendons, ligaments, nerves and osseus structures. Method Retrospective magnetic resonance imaging evaluation of the ankle and foot was done in 100 patients using 0.3T and 1.5T magnetic resonance imaging. Clinical history included pain, swelling of the ankle and foot, trauma, twisting injury, palpable mass and difficulty in walking. Result Fifty two patients were male and 48 patients female aged 6 months to 70 years. Ligaments tear were the commonest and seen in 22% patients. Tenosynovitis found in 17%, Pigmented villonodular synovitis (PVNS) in 3%, Achilles tendon abnormality in 8%, stress fracture-9%, osteomyelitis-8%, soft tissue vascular malformation in 5%, soft tissue and bone tumor-4%, marrow edema-20%, osteoarthritis-10%, Osteochondral lesion of talus-8%, sinus tarsi syndrome-3%, posterior impingement-5%, plantar fasciitis-2%, Sever disease-2%, peroneus tendon split-2%. The commonest clinical presentation was pain and swelling of the ankle in 42 patients, twisting/inversion injury of the ankle in 23 patients followed by traumatic injury with difficulty in walking in 20 patients and palpable mass in 8 patients. Ligaments injury were mostly associated with inversion/twisting injury. Conclusion Magnetic resonance imaging is advantageous for assessing soft tissue structures around the ankle and foot, such as tendons, ligaments, nerves, masses and occult osseus lesions. It provides a quick, non-invasive tool for the diagnosis of related injuries and guide for the further treatment planning.
