Ultrasound anatomic evaluation of normal and pathologic ligaments of the lateral aspect of ankle was performed. The objective of this study was to determine the usefulness of this exam in patients suggesting anterolateral impingement. Both sides were studied in fifteen (15) normal patients and in fourteen (14) patients submitted by the orthopedic surgeon with suggestive symptoms. Ligaments studied included: anterior tibiofibular, anterior talofibular and calcaneofibular. They were observed as an echogenic strip with posterior hypoechoic structures. Eleven (11) ligaments demonstrated alterations in eight (8) patients, with swelling and convexity of the strip. Four (4) patients had arthroscopic surgery and good correlation with ultrasound was found. Highresolution ultrasound can be a good diagnostic exam in anterolateral impingement especially if it is considered as an economic alternative when compared to MR. Key words: Ultrasound, Ankle.Resumen: Se realizó una evaluación de la anatomía ultrasonográfica de los ligamentos normales y patológicos de la región lateral del tobillo, con el objeto de determinar su utilidad en pacientes con clínica sugerente de pinzamiento anterolateral. Se estudiaron ambos lados en 15 pacientes sanos y en 14 pacientes referidos por traumatólogo con clínica sugerente. Los ligamentos evaluados fueron los: tibioperoneo anterior (TPA), peroneoastragalino (PA) y peroneocalcáneo. (PC) En pacientes sanos se observan como bandas ecogénicas, rectas, con estructura hipoecoica posterior. En 8 pacientes con sospecha clínica se detectó alteración en 11 ligamentos, observándose aumento de volumen y convexidad de la banda. A cuatro de estos pacientes se les practicó cirugía endoscópica encontrándose una buena correlación con los hallazgos ecotomográficos. En todos se indicó correctamente los ligamentos comprometidos.La ecotomografía de alta resolución puede ser un buen método diagnóstico en el pinzamiento anterolateral del tobillo a nivel de PA y TPA, especialmente si se considera como método alter nativo a la RM por su bajo costo y accesibilidad. Palabras Claves: Ultrasonido, Tobillo. Introducción Introducción Introducción Introducción IntroducciónEl pinzamiento anterolateral del tobillo (PAL) fue descrito por Wolin en 1950 y es producido por el anormal atrapamiento de partes blandas en la gotera anterolateral del tobillo. Los pacientes refieren dolor crónico, edema y limitación funcional. La mayoría de los casos tiene como principal antecedente la inversión reiterativa del tobillo. Después de estos episodios se estima que alrededor de un 10 a 50% de los pacientes presentan estos signos (1) .La lesión mencionada puede estar formada por tejido sinovial hipertrofiado, cicatriz fibrosa o un fascículo accesorio del ligamento tibioperoneo anterior.El diagnóstico diferencial es amplio, síntomas similares pueden ser atribuidos a inestabilidad cróni-ca del tobillo, ruptura o subluxación de los tendones peroneos, fractura de estrés, lesiones osteocondrales, coalición tarsal, pinzamiento óseo, y enfe...

“…It is often the preferred method for identification of bony and arthritic changes if plain radiography is inadequate in evaluating these changes in detail [8]. However, for the soft tissue impingement, CT arthrography may provide evidence of impingement including intraarticular oblique linear formation, nodular thickening of the capsule, or irregularity of the edges of the anterolateral groove of the ankle [33].…”

Anterior ankle impingement results from an impingement of the ankle joint by a soft tissue or osteophyte formation at the anterior aspect of the distal tibia and talar neck. It often occurs secondary to direct trauma (impaction force) or repetitive ankle dorsiflexion (repetitive impaction and traction force). Chronic ankle pain, swelling, and limitation of ankle dorsiflexion are common complaints. Imaging is valuable for diagnosis of the bony impingement but not for the soft tissue impingement, which is based on clinical findings. MR imaging and MR arthrography are helpful in doubtful diagnoses and the identification of associated injuries. Recommended methods for initial management include rest, physical therapy, and shoe modification. If nonoperative treatment fails, arthroscopic bony or soft tissue debridement both offer significant symptomatic relief with long-term positive outcomes in cases that have no significant arthritic change, associated ligament laxity, and chondral lesion.
