Anterolateral ankle joint swelling. Magnetic resonance arthrography (MRA) has been found to be accurate in 97% of anterolateral impingement cases and is used to identify ligament tears in the ankle.18 A lack of normal joint distention in the anterolateral Anterior ankle impingement generally refers to entrapment of structures along the anterior margin of the tibiotalar joint in terminal dorsiflexion. The AITFL is a flat band typically attaching to the distal tibia approximately 5 mm above the articular surface, anterior to the interosseous ligament, descending obliquely, attaching to the anterior aspect of the lateral malleolus4,3 (Figure 2). In spite of numerous arthroscopic procedure has considerable therapeutic advancements, diagnostic arthroscopy has always been the This results in thickening of the accessory AITFL, contributing to anterolateral impingement (Figure 5). PURPOSE: To determine the effectiveness of magnetic resonance (MR) imaging in the diagnosis of anterolateral impingement of the ankle. Both conditions can exist at the same time, leading to cam and pincer impingement or combined impingement. A distal separate ligament or fascicle of the AITFL has been described, located just distal to the AITFL, the accessory anterior inferior tibiofibular ligament. anteromedial impingement is a good, efficient approach to delineate synovial hypertrophy, and diagnose cartilage erosion therapy. Fortunately, non-operative management is often quite effective in treating this problem.

Anterolateral capsular thickening, hypertrophic scarring or a synovial meniscoid lesion will result in anterolateral ankle impingement 1. If present, an abnormally thickened Bassetts ligament is excised1, 14. The tibial attachment of Bassetts ligament may be less conspicuous due to blending of fibers with the AITFL. 0000189996 00000 n They are best classified according to location. +91- 880-029-9652. 0000016135 00000 n Axial T2-weighted fat-suppressed (Figure 10a) and axial T2-weighted non fat-suppressed (Figure 10b) images in different patients demonstrate ill-defined intermediate to low signal within the anterolateral gutter, consistent with synovitis and scarring (arrows). Soft tissue thickening, obstruction and distortion of the anterolateral gutter 1-5 sometimes with avulsed fragments or osseous bodies within the can be seen. However, it is important to appreciate the uncommon diagnosis and the role . Radiographs often show spurs in the anterior distal tibia or dorsal aspect of the talus. Anterolateral instability of the ankle joint: an anatomical, experimental and clinical study.

There is scar tissue and synovitis within the anterolateral gutter as well as a 5-mm osteochondral loose body. postulated that post-traumatic anterolateral hyperlaxity, due to an injured ATFL, results in anterior extrusion of the talar dome with dorsiflexion, contacting the accessory inferior fascicle of the AITFL, with more pressure and friction1, 3. The accessory anterior inferior tibiofibular ligament (also published in the radiology literature as Bassetts ligament)8 runs parallel and distal to the AITFL, also attaching to the tibia and fibula (Figure 3). US in Ankle Impingement Syndrome. J Am Podiatr Med Assoc. Glossary of Terms for Musculoskeletal Radiology. Antero-lateral tibio-talar synovectomy is performed as an arthroscopic procedure. What is your diagnosis? Thickened accessory anterior inferior tibiofibular (Bassetts) ligament, contributing to anterolateral impingement. For surgery, patients were placed on a traction table with a well-padded perineal post and were positioned in the supine position. Injections - reduces inflammation and control the pain, allows the rotator cuff muscles a chance to recover and improve with the exercises, 4. The distal tibiofibular joint is composed of a ligamentous complex including the anterior inferior tibiofibular ligament (AITFL), the posterior inferior tibiofibular ligament (PITFL), and the interosseous ligament. A fibular attachment point far from the joint level was also thought to result in greater risk. Wider and longer fascicles are potentially at greater risk. 0000100994 00000 n 2017;90(1070):20160735. 0000168556 00000 n Knee Surg Sports Traumatol Arthrosc. 0000138469 00000 n First line treatment for anterior ankle impingement is conservative which includes rest, ankle bracing, and avoidance of repetitive dorsiflexing activities such as jumping. This is when treatment is needed. Multiple factors may contribute to pain from anterolateral impingement, including synovitis, hyalinized scar tissue, and chondral injury of the talar dome 3. Basset et al. If they become big enough, or are further complicated by conditions such as impingement, they can become quite painful as tendons and other native tissues within the shoulder joint rub against them, causing inflammation and pain.

The pincer form is a consequence of excess acetabular coverage of the femoral head. A person with a type II or type III acromion would be at a higher risk of impingement due to the narrowing of the acromiohumeral gap and bursal space. Oblique axial proton density-weighted (1A) and coronal (1B) and sagittal (1C) T2-weighted fat-suppressed images are provided. Soft tissue impingement may occur after a lateral ligamentous injury of the ankle and results in chronic pain with mechanical symptoms. 0000189046 00000 n This accessory ligament is an anatomical variant present in the most ankles1, 4, 5, which may become sprained and pathologically thickened in the setting of inversion injury, resulting in impingement and mild residual anterior instability1, 3. Axial images are useful to identify the fibular attachment located inferior and slightly medial to the AITFL fibular attachment (Figure 8). 0000018740 00000 n In advanced cases, the mechanical impingement may mold tissue into a hyalinized meniscoid lesion, originally described by Wolin et al13, 4 (Figure 4). Pain with activities. 11(1):61-6, 2018, Molinier F et al: Does antero-lateral ankle impingement exist? The arthroscope is 4.0 mm in diameter.

If the foot is then moved into dorsiflexion the pain intensifies which is positive for synovial impingement. Am J Sports Med. 1991 Sep-Oct;19(5):440-6. van den Bekerom MPJ, Raven, EEJ. Skeletal Radiol. 0000018498 00000 n 0000009101 00000 n Since there are several distinct causes of chronic ankle pain, we prefer to call this problem "anterolateral impingement of the ankle" and believe the term "chronic sprain pain" should be discarded. Anterior and anterolateral talar dome articular cartilage abrasion has been reported to be present in 82.9%9, 17%5, and 71%1 of cases of an abnormal accessory AITFL. Pathologies that could do this are those directly affecting the rotator cuff such as: The acromion differs in individuals normally (morphological variants). The four muscles that raise and lower the arm (and their respective tendons) are collectively known as the rotator cuff . Nikolopoulos CE. Anterior ankle impingement can be due to scar tissue and inflammation or bone spurs that form in the anterior (front) of the ankle joint and limit range of motion and can cause pain. Figure 10 also demonstrates an abnormally thickened ATFL (arrowhead). Am J Roentgenol. Unable to process the form. 3 Sites of soft tissue impingement include anterolateral, posterior, and syndesmotic, with anterolateral impingement being the most common. Antero-lateral ankle impingement may occur following repeated ankle sprains or following a major sprain. Nikolopoulos later performed additional cadaveric studies concluding the structure was a distinct separate ligament from the AITFL due to the presence of an intervening fibrofatty septum4, 3. Treatment options include activity modification, physical therapy, and medications. Initial treatment is usually conservative with rest, physical therapy, taping, shoe modifications, nonsteroidal anti-inflammatory drugs and local corticosteroid injections, in conservative treatment failure management is usually arthroscopically 2,3. Palmer W, Bancroft L, Bonar F et al. Anterolateral ankle impingement has been known under the term anterolateral 'meniscoid lesion', which is the result of synovitis in the anterolateral gutter.
