Diagnostic imaging of ankle syndesmosis injuries: A general review. Kellett JJ, Lovell GA, Eriksen DA, Sampson MJ. Some studies have shown 3: Aside from being readily available, ultrasonography has the added benefit of being a real-time dynamic modality, allowing the operator to perform maneuvers on the ankle during imaging. Anterior syndesmosis: supplied by branches of the tibial and peroneal artery. Numerous measurements have been proposed for indirectly demonstrating syndesmotic injury but these vary across studies with no formed consensus. 1. The distal tibiofibular syndesmosis is a unique syndesmotic joint powerfully bound by a variety of ligaments to maintain the integrity of the ankle mortise. 2006 May 1;28(2):142-9. Injury to the syndesmosis occurs through rupture or bony avulsion of the syndesmotic ligament complex. For syndesmotic injuries, screws have been used as the gold standard for fixation 1.However, screw fixation results in limitation of the physiological mobility of the fibula, leading to complications such as screw breakage, malpositioning, and malreduction. The inferior segment assists in stabilising the tibiofibular syndesmosis. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). The objective of this study was to evaluate the motion of the syndesmosis under different loading patterns and determine the characteristics of the syndesmotic motion. Injury to the syndesmosis occurs through rupture or bony avulsion of the syndesmotic ligament complex. Considering the lengthy time until return to full activity, the ability of this condition to mimic or occur in combi- 2010 Dec 1;217(6):633-45. Anatomy of the ankle ligaments: a pictorial essay. Injuries to the ankle syndesmosis are commonly known as a "high ankle sprain". (2012) American Journal of Roentgenology. The mechanism of injury is uncertain but thought to be the combination of forceful foot external rotation with concomitant leg internal rotation 2. Injuries of the distal tibiofibular syndesmosis occur either isolated, or in combination with ankle fractures. Trapezoid shape (the tibial insertion is wider), Posterior or posterior-inferior tibiofibular ligament, Known as the Superficial component of the PITFL, Transverse ligament or the Transverse tibiofibular ligament, Also known as the Deep component of the PTIFL, Interosseus ligament or the interosseous tibiofibular ligament, Thickened portion of the distal interosseous membrane, Dense mass of short fibers with adipose tissue and small branching vessels from the peroneal artery, The most proximal fibres attach to the apex of the incisura tibialis on the tibia, Most distal fibres attach to the anterior tubercle of the tibia and descends straight to the talocrural joint of the fibula, The length of the fibres increase from proximal to distal, Buffer to neutralise forces during weight bearing as it transfers some of the axial compressive load to the fibula, 'Spring' action - allowing for minor separation between the distal tibia and fibula during dorsiflexion. The mechanism of injury is uncertain but thought to be the combination of forceful foot external rotation with concomitant leg internal rotation 2. 1 Injury to the tibiofibular syndesmosis destabilizes the ankle mortise and a minor shift in talar dome and the distal tibia or distal fibula … Although the syndesmosis is a joint, in the literature the term syndesmotic injury is used to describe injury of the syndesmotic ligaments. 1 Approximately 20% of the AITFL is intra-articular. Anatomical evaluation and clinical importance of the tibiofibular syndesmosis ligaments. Allowing slight wedging of the talus in the mortise. 182 (1): 131-6. Dr Christoph Agten. 4 (4): 146. Chronic distal tibiofibular syndesmosis disruption can be managed by endoscopic arthrodesis of the syndesmosis. 2 Direct signs of a ligamentous tear include: 2,4. N. Jarrod Durkee, Jon A. Jacobson, David A. Jamadar, John E. Femino, Madhav A. Karunakar, Curtis W. Hayes. Journal of anatomy. The distal tibia and fibula form the osseous part of the distal tibiofibular syndesmosis and are linked by the distal anterior tibiofibular ligament, distal posterior tibiofibular ligament, transverse ligament, and interosseous ligament . TightRope®. It is formed between the distal tibia(concave surface) and fibula(convex surface), with no articular capsule or synovial membrane as a fibrous joint, and attached by the interosseous ligament (IOL), the anterior-inferior tibiofibular ligament (AITFL), the posterior-inferior tibiofibular ligament (PITFL), and the transverse tibiofibular ligament (TTFL)[1][2]. The distal tibiofibular syndesmosis is a fibrous joint between the distal tibia and fibula that is stabilized by the distal anterior tibiofibular ligament, the distal posterior tibiofibular ligament, the transverse ligament, and the interosseous ligament.1Chronic syndesmosis disruption can result from missed diagnosis in the acute injury or after failed or inadequate … A fatty synovial fringe (small bundle of adipose tissue) moves during ankle movement. That is usually the journal article where the information was first stated. anterior inferior tibiofibular ligament (AITFL), posterior inferior tibiofibular ligament (PITFL), <2.8 mm (mortise view) has a sensitivity of 36% and specificity of 87% for syndesmotic injuries, acute ligamentous injury: hyperintense signal in the ligament with surrounding edema, chronic injury: thickened or disrupted ligament without edema, injuries to the high ankle tend to occur in order. Golanó P, Vega J, De Leeuw PA, Malagelada F, Manzanares MC, Götzens V, Van Dijk CN. Surgical and Radiologic Anatomy. Distal tibiofibular syndesmosis injuries are a relatively frequent ankle injury, although less common than a fracture or lateral ankle sprain. The contralateral, uninjured, ankle can be imaged for comparison. Provide strong stabilization and dynamic support to the ankle mortise, Maintain the integrity between the distal tibia and fibula, Resist forces (axial, rotational, and translational) that attempt to separate the two bones, 2° fibula external rotation relative to the tibia, As the ankle joint moves from end range plantar flexion to end range dorsiflexion the ankle mortise widens only about 1mm. A syndesmosis is a slightly movable fibrous joint in which bones such as the tibia and fibula are joined together by connective tissue. The distal tibiofibular syndesmosis is an important functional structure to maintain ankle stability during weight-bearing and walking. Injuries can occur to one or more of the structures that make up the distal syndesmosis1: 1. anterior inferior Examination of syndesmotic injuries or sprains. MRI has been shown to accurately detect injuries to the ligamentous structures of the distal tibiofibular syndesmosis 1-3. When refering to evidence in academic writing, you should always try to reference the primary (original) source. (2017) Sonography. Treatment of syndesmotic injuries or sprains. Injury of the Tibiofibular Syndesmosis: Value of MR Imaging for Diagnosis1.

Ankle syndesmosis injuries: anatomy, biomechanics, mechanism of injury, and clinical guidelines for diagnosis and intervention. in intermediate injuries without syndesmotic widening on non-weight bearing x-rays and MRI. The equilibrium of the distal tibiofibular syndesmosis is offered by the structure of the portion of the intervening ligaments and fibula and the tibia. A stable and precise articulation of the distal tibiofibular syndesmosis is essential for normal motion of the ankle joint. High ankle sprains: Easy to miss, so follow these tips Arthroscopic diagnosis of tibiofibular syndesmosis disruption. 7. Introduction Inversion ankle sprains seldom present a diagnostic di-lemma to the experienced practitioner; however injuries to the distal tibiofibular syndesmosis often go unnoticed. A stable and precise articulation of the distal tibiofibular syndesmosis is essential for normal motion of the ankle joint. (2009) The American Journal of Sports Medicine. Sharmaine McKiernan, Michelle Fenech, Deborah Fox, Ian Stewart. This is performed through the proximal anterolateral and posterolateral portals. The ligaments are: Ankle injuries may involve the distal tibiofibular syndesmosis and can be associated with a variable degree of trauma to the soft-tissue and/or osseous structures that play an important role in ankle joint stability. and in rare cases by branches from the tibial artery. Sonographic Evaluation of Lower Extremity Interosseous Membrane Injuries. A Dynamic Ultrasound Examination for the Diagnosis of Ankle Syndesmotic Injury in Professional Athletes: A Preliminary Study. The distal tibiofibular syndesmosis is composed of the anterior and posterior inferior tibiofibular ligaments, interosseous ligament, interosseous membrane, and medial deltoid ligament .Disruption of the distal tibiofibular syndesmosis to any degree is regarded as an important cause of ankle instability and can result in prolonged disability after an ankle fracture … The distal tibiofibular syndesmosis, between the fibula and tibia, is formed by three major ligaments: the anterior inferior tibiofibular ligament (AITFL), the posterior inferior tibiofibular ligament (PITFL), and the interosseous tibiofibular ligament (ITFL). Syndesmotic injury may occur solely as a soft-tissue injury or in association with ankle fracture. The tibiofibular syndesmosis is a complex fibrous joint composed of multiple ligaments and a broad fibrous interosseous membrane that spans between the tibia and fibula throughout the length of both bones. External rotation of the talus has been identified as the major mechanism of syndesmotic injury. The scar tissue and bone block are resected to facilitate the subsequent reduction of the syndesmosis. Knee Surgery, Sports Traumatology, Arthroscopy. 37 (5): 1009-16. The function of syndesmosis ligament complex: Injury to the syndesmotic joint is described in the literature as an injury to the syndesmotic ligaments[1].
