The typical symptoms are of chronic anterior ankle pain with subjective feeling of blocking on dorsiflexion. Aliasing is reduced or eliminated by repositioning the extremity (eg, plantar flexing the hindfoot to prevent images of the toes from superimposing on the heel), by orienting the phase-encoding direction anterior-to-posterior when possible, by shielding body parts outside of the area of interest, or by the use of phase oversampling [148,174,175].

Injury of the tibiofibular syndesmosis: value of MR imaging for diagnosis. Plantar flexion, which is possible with the patient either supine or prone, also reorients the medial and lateral ankle tendons so that a single imaging plane will show a larger length of each in cross-section and so that a smaller segment of each tendon will pass through the magic angle [150,151]. 46. 115.

It is important to note the mediolateral extent of the interposition of an otherwise normal (i.e., not thickened and/or edematous) plica between the patella and prefemoral fat pad or femur in the MRI report, as such an interposition may predispose the patient to medial synovial plica syndrome that may develop later.

Enter your email address below and we will send you the reset instructions. Impingement syndromes are just one possible etiology of persistent ankle pain, and although the diagnosis is often made or suspected clinically, the radiologist might be the first person to raise the possibility of the diagnosis or be called upon to provide support for the clinically suspected diagnosis. 43, No. On examination, there is restricted and painful dorsiflexion. William T. Herrington, MD, FACR Biomechanically, LHI is the sequela of lateral transfer of weight bearing from the central talar dome to the lateral talus and fibula. AJR Am J Roentgenol.

A 17-year-old girl with left anterior knee pain for the last five years. Illustrates supination and pronation, hammertoe, bunion, sprains, fractures and fracture fixation. Iliopsoas impingement is considered to arise in patients in whom there is an intimate relationship between the iliopsoas tendon and anterior aspect of the acetabular labrum, with focal injury at the latter (13). a, b. The equipment and medications should be monitored for inventory and drug expiration dates on a regular basis.

MATERIALS AND METHODS: Legg-Calve-Perthes disease: from childhood to adulthood. MRI of the ankle joint is useful in excluding other causes of pain that may clinically mimic anterior ankle impingement syndrome, such as occult stress fracture of the anterior aspect of distal tibia and osteochondral lesion of the medial talar dome , .MRI is also useful in assessment of the degree of chondral damage and in detection of capsular thickening and synovial inflammation in the . 1996;166(5):1079-1084. Fluid-sensitive MRI sequences, such as fat-saturated proton-density-weighted or T2-weighted imaging, or short tau inversion recovery in routine imaging planes are usually sufficient to ascertain the presence of such edema-like changes. 178. Although initially described as a condition following hip surgery, it was later recognized on MRI as an entity that might occur without such a history (20). 2) (4), and slipped capital femoral epiphysis (5). 2008;28(5):1493-1518. 2015;35(1):164-178. 21, No. 96. 9). 2001;30(4):179-191. Magn Reson Imaging Clin N Am. 2 ). Shown to be highly accurate in detecting acetabular labral lesions (8), MR arthrography is used in patients who are suspected to have labral tears in association with femoroacetabular impingement in whom conventional MRI is indeterminate or has equivocal findings. AJR Am J Roentgenol. Bureau NJ, Cardinal E, Hobden R, Aubin B. Posterior ankle impingement syndrome: MR imaging findings in seven patients. 6. 2, Clinical Journal of Sport Medicine, Vol. Magnetic resonance imaging (MRI) is a proven imaging modality for the detection, evaluation, staging, and follow-up of disorders of the ankle and hindfoot. Standard MR software also allows the prescription of oblique images in virtually any plane, if images oriented along the course of a given structure are needed [154]. 151. An official website of the United States government. Note the bony protuberance (asterisks, The lateral synovial recess of the anterior aspect of the knee joint should not be mistaken for edema representing iliotibial band friction syndrome on MRI.

Pedal abscesses in patients suspected of having pedal osteomyelitis: analysis with MR imaging. Approximately 1% of the world's adult population is affected by ankle osteoarthritis (AO). 2, Clinical Journal of Sport Medicine, Vol. 7 ). 02, Foot & Ankle International, Vol. These impingements are sequelae of flatfoot deformity and hindfoot valgus from a variety of causes such as posterior tibial tendon (PTT) deficiency, rheumatologic disorders, diabetes, calcaneal fractures, and congenital flatfoot [ 7, 8 ]. We use a checklist when evaluating an MRI of the Ankle: Bones: screen on fatsat images for bone marrow edema. If the foot is then moved into dorsiflexion the pain intensifies which is positive for synovial impingement. Reporting should be in accordance with the ACR Practice Parameter for Communication of Diagnostic Imaging Findings [181]. Adherence to the following parameters will increase the probability of detecting clinically important abnormalities. Femoroacetabular impingement. MR imaging has the advantage over ultrasound in being able to assess for whole ankle pathology, including coexisting or alternative causes of prolonged ankle pain, such as marrow contusions, chondral lesions, intra-articular bodies, and sinus tarsi syndrome. 11). The physician should be familiar with relevant ancillary studies that the patient may have undergone. 1996;200(3):833-841. Paul A. Larson, MD, FACR Foot Ankle Int. Lee JC, Calder JD, Healy JC. Some anatomical variants or conditions that might have predisposed the child to these impingement or friction syndromes also need to be considered for correct diagnosis while evaluating MRI examinations of the lower extremities in children. The overall prognosis after surgery does depend on the degree of degenerative change evident in the rest of the tibiotalar joint at the time of the surgery. First proposed in 2011 (13), iliopsoas impingement is currently considered to be an extra-articular type of hip impingement syndrome (14), which is being increasingly recognized.

Diego Jaramillo, MD, MPH 6, Journal of the Korean Society of Radiology, Vol. Slice thickness should be 4 mm or less to minimize partial-volume effects, but thinner sections may be advantageous for detailed analysis of the ligaments and articular cartilage. MR imaging is particularly valuable in being able to detect not only the soft tissue and osseous abnormalities involved in these syndromes, but also a wide variety of other potential causes of ankle pain and instability that also may need to be addressed clinically. Dussault RG, Kaplan PA, Roederer G. MR imaging of Achilles tendon in patients with familial hyperlipidemia: comparison with plain films, physical examination, and patients with traumatic tendon lesions. Donovan A, Rosenberg ZS. The two This is certainly not the case in the anteromedial ankle, where cadaveric analysis has shown that the bony spurs are intra-articular, consistent with osteophyte formation. 15.

American College of Radiology. 1994;162(2):377-383. Common sites of impingement in the ankle include posterior, posteromedial, anteromedial, anterolateral, and, less commonly, direct anterior; these often coexist and occur in conjunction with other ankle pathologies. Posterior impingement, subdivided into posterior and posteromedial impingement. Radiology. Avoiding gradient-echo imaging and reducing the voxel size by increasing the imaging matrix and/or decreasing the slice thickness and FOV will help reduce the magnitude of susceptibility artifacts [174]. 10). Thus, an approach that differs from the guidance in this document, standing alone, does not necessarily imply that the approach was below the standard of care.
