PTFL MRI

PTFL. The Posterotalofibular ligament courses posterior to the lateral tubercle on the posterior aspect of the talus. Isolated injury is very rare. When it is injured, there has to be injury to the other lateral ligaments. Here a normal PTFL and a grade 2 tear. Notice that there is also a grade 2 tear of the ATFL Purpose: Magnetic resonance imaging (MRI) has relatively low accuracy in diagnosing chronic anterior talofibular ligament (ATFL) injury. This study's purpose was to evaluate the angle between the ATFL and posterior talofibular ligament (PTFL) as a new indirect MRI sign of chronic ATFL injury in patients with mechanical ankle instability (MAI) MRI is the modality of choice for evaluating osteochondral injuries as it can detect signs of instability, including a rim of fluid signal intensity surrounding the lesion, cysts underlying the lesion, (CFL), and finally the posterior talofibular ligament (PTFL). 6 On MRI, the ligaments appear as thin, linear, low-signal intensity structures connecting adjacent bones, usually delineated by high-signal intensity fat. Lateral Complex. The lateral complex comprises the anterior talofibular (ATFL), posterior talofibular (PTFL), and calcaneofibular (CFL) ligaments mri Both the anterior and posterior talofibular ligaments are usually seen on a single axial image obtained slightly distal to the tibiofibular ligaments 4 . Heterogeneity with increased intraligamentous signal intensity on fat-suppressed T2-weighted or intermediate-weighted images is indicative of intrasubstance edema or hemorrhage

1. As is typically seen in cases of PTFL sprain, MRI additionally showed associated sprains of the ATFL and CFL that were not identified on 99m Tc-MDP SPECT/CT, the former can be seen in (e) where there is thickening and periligamentous oedema of the ATFL
2. The ATFL is the weakest ligament of the lateral ligamentous complex, followed by the CFL. 18 Hence, there is a predictable sequence of injury in lateral ankle sprains, first involving the ATFL, followed by the CFL, and finally, the PTFL.19, 20 The ATFL and CFL are commonly injured, whereas the PTFL is rarely torn except in cases of complete dislocation of the ankle. 21 The most common mechanism of injury is inversion stress and the MRI may show the ATFL to be attenuated, lax, or.
3. Injuries were classified on MRI as complete or partial tears of the anterior-inferior tibiofibular ligament (AITFL), posterior-inferior tibiofibular ligament (PITFL), anterior talofibular ligament (ATFL), posterior talofibular ligament (PTFL), calcaneofibular ligament (CFL), and deltoid ligament

In summary, injury to CFL and PTFL in the presence of an intact ATFL is rare. When a low ankle sprain is suspected, MRI assessment of the CFL and PTFL can be very helpful and, in our experience, is an important part of the evaluation because it can provide useful information as to the structural integrity of the anatomic structures PTFL - Posterior talofibular ligament. Looking for abbreviations of PTFL? It is Posterior talofibular ligament. Posterior talofibular ligament listed as PTFL. Posterior talofibular ligament - How is Posterior talofibular ligament abbreviated? MRI of the ankle The connections of the os trigonum and posterior talofibular ligament (PTFL), the fibulotalocalcaneal ligament (FTCL), the paratenon of the Achilles tendon, the posterior talocalcaneal ligament (PTCL), the osteofibrous tunnel of the flexor hallucis longus (OF-FHL) and the flexor retinaculum (FR) were studied

The length and the thickness of the ATFL and PTFL were measured. In coronal images The length and thickness of Posterior Tibiotalar Ligament were measured. 3. Results Out of the total 30 MRI scans taken for study, the mean age of male and female in the study was 37 and 33 respectively. Out of 30 MRI images, 17 were of left ankle and 13 fro This study's purpose was to evaluate the angle between the ATFL and posterior talofibular ligament (PTFL) as a new indirect MRI sign of chronic ATFL injury in patients with mechanical ankle. PTFL injuries were observed only in the presence of concomitant ATFL and CFL injuries. The complexity of deltoid ligament and syndesmosis injuries on MRI was documented in Table 2. MRI showed deltoid ligament injury in 18 patients (36%) (superficial ligament alone, 9; deep ligament alone, 2; both ligaments, 7)

Further imaging such as ultrasound and magnetic resonance imaging (MRI) should be considered if pain persists for 8 weeks following the sprain. 42, 44 Low ankle sprains can be classified into three grades as seen in Table 3 . 42 When ultrasound scanning, if the ligaments appear normal and there is a small amount of fluid seen, then the sprain is a grade I (Figure 6 A) MRI is an excellent technique for those cases where the diagnosis is uncertain as it can exclude most clinically relevant pathologies, especially when surgical interference is planned. On conclusion, our study aimed to compare the diagnostic accuracy of both ultrasonography and magnetic resonance imaging for the assessment of tendons and ligaments around the ankle joint talofibular ligament (PTFL).

Both ultrasonography and MRI can be valuable in diagnosing any concomitant chondral or tendon injury. Recently a study compared ultrasonography in the emergency room with MR images for injuries of the ATFL and found no differences in diagnosticaccuracy.27 Thesensitivity andspecificity of MRIin diagnosing ATFL injuries are 92%-100% and 100% This article provides an overview of the MRI features of normal and abnormal ligaments of the ankle (Appendix 1). Injured ligaments on MRI may appear disrupted, thickened, heterogeneous, or attenuated in signal intensity, and may be abnormal in contour. Fluid-sensitive sequences are often helpful in detecting injury The PTFL occupies the distal segment of the concavity of this groove, whereas the fiber of the ITL is located above and slightly anterior to the PTFL and filled-in proximal segment of the groove. The PITFL is inserted superoposterior to the ITL. (MRI) through a visual grading analysis (VGA) study. Radiography, Vol. 23, No. 2

Posterior Ankle Impingement - Radsourc

The Anterior Talo-Fibular Ligament (ATFL) is one of three ligaments that make up to Lateral Collateral Ligament of the ankle. The ATFL is a short ligament that widens slightly from top to bottom.[1 Poster: ESSR 2013 / P-0007 / The Role of Dynamic Ultrasound and MRI in the poorly resolving ankle sprain. by: J. M. Zietkiewicz , P. Mercouris, M. C. Marshall; Durban/Z The posterior tibiofibular ligament is a fibrous band of connective tissue that travels horizontally over the rear surface of the tibiofibular syndesmosis, which is a meeting area of the fibula.
