Abstract
Background: The ankle joint (Talocrural articulation) is a hinge-type
synovial joint. It is one of the frequently injured joints and as such
ligament injury is a more common pathology. The most common ankle
injuries are sprains and fractures, which involve ligaments and bones in
the ankle. Ankle joint can also be affected by inflammatory, infectious
and tumoral lesions. Magnetic resonance (MR) imaging has opened new
horizons in the diagnosis and treatment of many diseases affecting the
ankle and foot.
Objectives: This study was designed to assess the Magnetic Resonance
imaging findings/patterns of ankle joint pathologies in patients who
presented with ankle joint compliant.
Method: Hospital based retrospective descriptive cross-sectional study
was conducted at Tikur Anbessa Specialized Hospital and Saint Pauls
Millennium Medical Collage Hospital within a period of 30 months from
January 2018 to June 2020G.C to address the specific objectives stated.
Data was collected using structured questionnaires from picture archiving
and communication system (PACS) system, from both manual and
electronic patient recordings. Magnetic Resonance Images were evaluated
for result correspondence. Computerized Data analysis was conducted by
using Statistical Package for the Social Science (SPSS) version 25
software
Result: A total of 114 patients were imaged with Magnetic Resonance
Images in the two hospitals over the last 30 months and among them
75(56.8%) were females and 39(34.25) were males. The commonest age
involved was between 31-40 and 21-30 years with age range from 787years.

(35.1%)

detected
with MRI followed by tendon pathology (28.9%) and joint
effusion (26.3%). Tenosynovitis is the commonest tendon lesion detected
followed by tendinopathy which is more common in Achilles tendon, the
commonly involved tendon among tendons at ankle joint. Anterior
Talofibular ligament is the commonly injured ligament in 72.7% of the
cases with ligament lesions. Study showed 11 different types of tumor
lesions (Giant cell tumor was more common), 5 cases with Haglund
syndrome and 2 cases of Madura foot.
Conclusion: Magnetic Resonance Image has a special quality in detecting
bone, tendon, ligament and soft tissue pathologies irrespective of the
etiology and our study confirmed this quality of detecting wide array of
pathologies. Magnetic Resonance Image is an irreplaceable imaging
modality in Musculoskeletal system imaging and its accessibility has led
to increased detection of pathologies of the ankle joint which otherwise
wouldn’t have been detected. Detection of minor fractures, bone
contusion, small soft tissue lesions in detail made MRI gold standard
imaging modality in Ankle joint.
