Difficulty achieving anatomic alignment of the syndesmosis is due to variable morphology of the fibular incisura of the tibia and a paucity of literature regarding its morphologic characteristics. Syndesmosis – connecting materials is a interosseous membrane. Reduction of the posterior malleolus fracture was assessed as anatomical in 14 cases and as satisfactory in five cases. Conclusion: The articular surfaces of this joint are the triangular convex surface on the medial aspect of the distal end of the fibula and the reciprocally concave fibular notch on the distal end of tibia. The inferior tibiofibular joint (also distal tibiofibular joint, inferior tibiofibular syndesmosis, distal tibiofibular syndesmosis, latin: syndesmosis tibiofibularis) is a fibrous joint between the fibular notch of tibia and distal epiphysis of the tibia. The patients were apportioned accordingly to either a DTS contained- or separate-type group (average ages 45 and 42.1 years, respectively; 19 men/26 women and 24 men/23 women).

The inferior tibiofibular joint is reinforced by strong ligaments. The aim of the study was to assess the variability of a notch between the upper rim of the glenoid and the coracoid base, the so-called coracoglenoid notch (CGN), and its clinical significance.Materials and methodsThe study was based on the examination of 204 dry bone specimens of adult scapulae (92 male and 112 female). On conventional CT, the mean Tang ratio was 0.97 ± 0.06; the mean anterior tibiofibular distance was 2.17 ± 0.87 mm; the mean posterior tibiofibular distance was 3.52 ± 0.94 mm; and the mean depth of fibular incisura was 3.29 ± 1.19 mm. Results: The distance between the distal attachment of this ligament and the joint line ranged from 16.2 to 33.1 mm (mean, 24.0 mm ± 4.8). This straightening was associated with a relative sigmoidal curve accentuation in the M-L plane. A total of 51 patients were treated operatively, and in 38 of these an open procedure was performed. The cases of 120 volunteers who underwent bilateral ankle CT were retrospectively reviewed. Reduction of the distal fibula, ]. 35. This study provides measurements of the normal tibiofibular syndesmosis in a Chinese population. Radiographic evaluation included the anterior tibiofibular clear space (ATFCS), posterior tibiofibular clear space (PTFCS), anterior tibiofibular interval (ATFI), length of incisura (LI), depth of incisura (DI), and fibular width (FW). The majority of ankles (79%) demonstrated coexistent marginal erosions and/or joint narrowing. A number of metric methods have been developed for the assessment of … Its main function is to act as an attachment for muscles, and not as a weight-bearer. When these grafting procedures are performed, people are able to function very normally, despite missing a large part of the fibula bone… Our study is the first (1) to apply longitudinal curvature analysis in the antero-posterior (A–P) and medio-lateral (M–L) planes to the human tibia, and (2) that incorporates a broad temporal population sample including the periods of intensification of agriculture, urbanization and industrialization (from 2900 BC to the 21st century AD; N = 435) within Czech territories. The mean AOFAS score was 89.4 points. With the median values of the control group as cutoff there were 71% shallow, 71% disengaged and 77% retroverted syndesmoses in the injury group. It also defines the frequency of DTFS measures and the interobserver performance on 2 CT evaluation methods. Given the timescale involved and the known phenomenon of declining mobility, such adaptive changes in bone geometry can be interpreted in terms of the diminishing biomechanical demands on the tibia under different living conditions. To improve the diagnostic accuracy of distal tibiofibular syndesmoses (DTS), this study quantified the range in variations of the normal DTS in a Chinese population, based on CT scan images. Ankle These calibrated parameters showed significant differences according to age (p = 0.009, 0.006, and <0.001, respectively). https://en.wikipedia.org/w/index.php?title=Fibular_notch&oldid=870811949, Creative Commons Attribution-ShareAlike License, This page was last edited on 27 November 2018, at 04:14. Introduction Articulation: fibular notch of tibia and disto-medial fibula - severely restricts motion - ligamentous support (anterior/posterior tibiofibular) Interosseus Ligament: - extension of interosseus membrane - Joint designed for stability - ligaments minimize separation as weight of body transmitted to talus Although Maisonneuve fracture (MF) is a well-known type of ankle fracture–dislocation, there is still a lack of information about the epidemiology and the extent of all associated injuries. The study comprised 54 adult patients. The inferior tibiofibular joint is a syndesmosis joint (slightly movable, fibrous joint), just above the ankle region which lies between the medial distal end of the fibula and the concave fibular notch region of the lateral tibia. ATFCS, PTFCS, and ATFI were significantly different among the age groups (p = 0.001, 0.001, and <0.001, respectively). Fractures of the posterior malleolus were identified in 43 of 54 patients (80%). At the lower end of the tibia there is a medial extension (the medial malleolus), which forms part of the ankle joint and articulates with the talus (anklebone) below; there is also a fibular notch, which meets the lower end of the shaft of the fibula. Fibular notch – Finally, we have the fibular notch, which is a depression that allows for the attachment of the fibula bone, forming the distal tibiofibular joint. Five morphologic variations of the fibular incisura were identified: crescentic, trapezoid, flat, chevron, and widow's peak. It consists of strong bands that extend from the fibular notch of the tibia to the medial surface of the distal end of the fibula. Axial CT images of the normal syndesmosis showed significant differences according to gender and age, but not between sides. The presence of a deep, or shallow, notch may constitute an anatomical predisposition to a fracture of the anatomical neck. The fibular notch of the tibia In light of the anatomical variation, narrowing of the syndesmotic joint due to anterior translation of the fibula following aging may represent the most significant finding. The most common fibular incisura morphology was crescentic (61.3%), followed by trapezoid shape (25.1%); the least common morphology was flat (3.1%). There was no side-to-side variability seen in this study. To describe the distal fibular notch, an infrequently described manifestation of rheumatoid arthritis, and to speculate on its etiology through gross dissection, histologic correlation and MR imaging. Results The morphology of the distal tibiofibular syndesmosis can determine the pathology and mechanism of syndesmotic injury. The fibula's role is to act as an attachment for muscles, as well as providing stability of the anklejoint. The length, anterior, extra-anterior, posterior, and extra-posterior indices were successfully calculated. Results Tang ratios for fibular rotation, anterior and posterior tibiofibular distances, fibular incisura depth, and subjective morphologies on CT were assessed using conventional multiplanar reconstruction (MPR) and maximum intensity projections (MIPs). The tibia is connected to the fibula by the interosseous membrane of the leg, forming a type of fibrous joint called a syndesmosis with very little movement. Conclusions: June 2008 to December 2011, and 203 (26.2%) were included for evaluation. There were no significant differences between sides. In a study performed by Ebraheim et al., 60% cases presented a deeply concave and 40% shallow concave fibular notch.3 While Taser et al., in his study found 35% deeply concave and 65% shallow concave fibular notch.12 There is a relationship between the position of the fibula and recurrent ankle instability. The fibular notch of the tibia is an indentation at the inferior portion of the tibia where it articulates with the fibula to form the inferior tibiofibular articulation. Articular surface of the tibia – The distal end of the tibia will transfer weight to the foot at its articulation with the talus bone, forming the ankle joint. April 2018; National Journal of Clinical Anatomy 7(02):069-073; DOI: 10.1055/s-0040-1701712 While using the fibular notch approach, the ATFL is the only possible ligament that sometimes needs to be cut off for sufficient exposure of the fracture. The strong anterior and posterior tibiofibular ligaments also strengthen the distal tibiofibular joint anteriorly and posteriorly. The goal of this study was to assess whether human tibial curvature reflects this decline, with a special emphasis on the time-span during which the pace of technological change has been the most rapid. Held by 4 tibiofibularsyndemostic ligaments. tibia (tibial plafond) 18.9 mm. Secondly, how are tibia and fibula connected? 45. Malreduction of distal tibiofibular syndesmosis (DTFS) leads to poor functional outcomes after ankle fracture surgery. The mean longitudinal/transverse length of the distal fibula at the level of the syndesmosis was 1.2 mm (1.3 mm in males; 1.2 mm in females; 1.1 mm for concave; 1.3 mm for shallow). Meanwhile, when the ankle was positioned from the neutral position to 10° dorsiflexion, the distal fibula tended to move laterally and posteriorly and rotate externally. 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. Under the axial loading, the distal fibula tended to move medially and anteriorly and rotate internally with the ankle positioned from the neutral position to 15° plantar flexion. Distal tibiofibular joint – articulates with the fibular notch of the tibia. RESULTS: The distal fibular notch was identified in 52 of 121 ankles (43%). Conclusions: The most proximal fibers of the IOL attached to the tibia at the top of the fibular notch. Results: The relative motion of the syndesmosis was correlated to the ankle position and loading patterns. This issue has not yet been adequately addressed in the literature. The lower leg is made up by two bones - the tibia and fibula. Conclusion: It is impossible to assess the shape and size of the posterior malleolar fragment, involvement of the fibular notch, or the medial malleolus, on the basis of plain radiographs. Introduction: Materials and methods The depth, fibular engagement and rotational orientation of the tibial incisura were analyzed. The distal (inferior) tibiofibular joint consists of an articulation between the fibular notch of the distal tibia and the fibula. Levels of Evidence: Anatomical, Level V. disruption and control group of 75 patients with unrelated foot problems were compared. Two observers performed quantitative measurements and qualitative evaluated fibular incisura morphology. Wide variability in morphometrics and, thus, anatomy of IF were observed in the present review, which was influenced by gender. Results showed the continuous trend of A-P straightening of the shaft. It articulates with the talus, forming the lateral portion of the ankle (mortise) joint. Design and patients: One hundred and twenty-one conventional ankle radiographs were obtained and reviewed in 76 patients with clinically diagnosed rheumatoid arthritis. scans. The mean posterior TFD was 5.9 ± 1.6 mm (6.7 ± 2.1 in males; 5.7 ± 1.3 mm in females; 5.5 ± 1.3 mm for concave; 6.5 ± 1.9 mm for shallow). concave (<4 mm) fibular notch. The syndesmoses with a deep incisura and the fibula not engaged into the tibial incisura were at risk of overcompression, anteverted incisuras at risk of anterior fibular translation, and retroverted incisuras at risk of posterior fibular translation. On conventional CT, the mean Tang ratio was 0.97 ± 0.06; the mean anterior tibiofibular distance was 2.17 ± 0.87 mm; the mean posterior tibiofibular distance was 3.52 ± 0.94 mm; and the mean depth of fibular incisura was 3.29 ± 1.19 mm. Right Tibia, posterior view. The aim of study is to describe MF pathoanatomy on the basis of radiographs, CT scans and intraoperative findings. It has three main articulations: Proximal tibiofibular joint – articulates with the lateral condyle of the tibia. Bones of the right leg. The skin and muscles were removed with all ligaments around the syndesmosis and knee and ankle joint intact. its widest point was 23.6 mm, at 3 mm abov e the tibiotalar joint space 22 mm, 10 mm above this articular surface of distal. Injuries can occur to one or more of the structures that make up the distal syndesmosis1: 1. anterior inferior tibiofibular ligament (AITFL) 2. posterior inferior tibiofibular ligament (PITFL) 3. transverse tibiofibular ligament 4. interosseous membrane 1. anterior talofibular ligament injury 2. fracture/ bone contusion 3. talar dome osteochondral injury 2 The mean anterior TFD was 2.2 ± 0.8 mm (2.4 ± 0.8 mm in males; 2.1 ± 0.8 mm in females; 2.1 ± 0.8 mm for concave; 2.2 ± 0.9 mm for shallow). Two observers performed quantitative measurements and qualitative evaluated fibular incisura morphology. On average, the following intraindividual variations were observed: superior tibiotalar clear space of 0.27mm and 0.15mm medial; and anterior tibiofibular distance of 0.42mm, 0.38mm posterior and 0.24mm in the incisural notch. The incisura fibularis was concave in 64.2% of the feet and shallow in 35.8%. This review article outlines the MRI anatomy and pathology of this joint. The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. The system that we propose for classification of fractures of the posterior malleolus is based on CT examination and takes into account the size, shape and location of the fragment, stability of the tibio-talar joint and the integrity of the fibular notch. It is stabilized by three main ligaments: the anterior inferior tibiofibular ligament, the posterior inferior tibiofibular ligament, and the interosseous tibiofibular ligament, which are well delineated on magnetic resonance imaging. Incisura depth, fibular engagement into the incisura, and incisura rotation were correlated with degree of syndesmotic malreduction in coronal and sagittal planes as well as rotational malreduction. Now let’s look at the bone that articulates with the tibia and fibula to form the ankle joint - the talus. You can help Wikipedia by expanding it. DISTAL TIBIOFIBULAR JOINT • TYPE: FIBROUS JOINT • ARTICULATION: • Articulation is between fibular notch at the lower end of the tibia and the lower end of the fibula • There is no capsule • BLOOD SUPPLY:perforating branch of the peroneal artery,and the malleolar branch of the anterior and posterior tibial arteries. Level of evidence: The present study has provided measurements of the normal tibiofibular syndesmosis in the Japanese population. Further variations in the position of the fibula relative to the tibia were quantified with length, anterior, and posterior indices. The inferior tibiofibular joint is a fibrous joint, precisely a syndesmosis. The baseline characteristics of the contained- and separate-type groups were statistically comparable. Posterior surface. The fibula is a bone located within the lateral aspect of the leg. While the fibula is an important bone, it is possible to excise much of the bone for surgical procedures where bone is needed elsewhere in the body. The depth of the incisura fibularis, anterior tibiofibular distance (TFD), posterior TFD, and longitudinal/transverse length of the distal fibula were measured. No significant difference in CGN was found between the sexes, or between the right and left sides. Fibrous joint between convex medial surface of distal fibula and concave fibular notch of the distal tibia. When compared with our six cases of the anatomical neck fracture of the scapula, two patients displayed CGN type A and type B, respectively; but in four patients, it was impossible to distinguish between types A and B.Conclusion The most common fibular incisura morphology was crescentic (61.3%), followed by trapezoid shape (25.1%); the least common morphology was flat (3.1%). a hollow on the lateral surface of the lower end of the tibia in which the fibula is lodged. The distal tibiofibular syndesmosis is an important structure for ankle stability. Five morphologic variations of the fibular incisura were identified: crescentic, trapezoid, flat, chevron, and widow's peak. Purpose: Morphometric study of human fibular incisura in dry bones. Results An axial load of 600 N was applied to the specimens with the ankle joint in 10° dorsiflexion, neutral position, and 15° plantar flexion using a universal material testing machine. The study stresses the need to consider the anatomical and gender-based variability while assessing syndesmotic stability and further supports the recommendation of side-to-side comparison. Three-Dimensional Computed Tomographic Characterization of Normal Anatomic Morphology and Variations... Is Incisura Fibularis a Reliable Landmark for Assessing Syndesmotic Stability? The anatomy of the syndesmosis is variable, yet little is known on the correlation between differences in anatomy and syndesmosis reduction results. The inferior tibiofibular articulation (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the lower end of the fibula, and a rough concave surface on the lateral side of the tibia. Offered as a reference, these data should improve diagnosis of injury of the DTS. The aim of this study was to analyze the correlation between syndesmotic anatomy and the modes of syndesmotic malreduction. Objective. The position of the fibula relative to the fibular notch (incisure) of the tibia was quantified by inclusion or separation indices, based on whether the fibula was within or outside the fibular incisure, respectively. Outcomes of the study demonstrated good mid-term results in type four fractures of the posterior malleolus treated by direct reduction from posterior approaches. The ACL arises from the lateral or outside condyle and from within the fibular notch, which is the indentation between the condyles, while the PCL behind it attaches to the medial or inside condyle. The fibular notch of the tibia is an indentation at the inferior portion of the tibia where it articulates with the fibula to form the inferior tibiofibular articulation. It also defines the frequency of DTFS measures and the interobserver performance on 2 CT evaluation methods. Several lines of bioarchaeological research have confirmed the gradual decline in lower limb loading among past human populations, beginning with the transition to agriculture. The fibular fracture—fibular head was involved in four cases, and the subcapital region of the proximal quarter of the fibula was affected in 50 cases. Level IV, case series. Results: A fibula fracture occurs when there is an injury to the smaller of the two bones of the lower leg (the segment between the knee and ankle), the fibula. Conclusion LI and FW were significantly smaller in the women (p <0.001, <0.001). Coronal and axial MR imaging planes best … A total of six patients developed osteoarthritic changes of grades one and two according to the Kellgren and Lawrence classification. MF was defined as an ankle fracture–dislocation with a fracture of the fibula in its proximal quarter. Tang ratios for fibular rotation, anterior and posterior tibiofibular distances, fibular incisura depth, and subjective morphologies on CT were assessed using conventional multiplanar reconstruction (MPR) and maximum intensity projections (MIPs). ICC for incisura shape and depth assessments was poor on both modalities (0.13 to 0.38). Pathology of the distal tibiofibular joint is mostly related to trauma and the longer-term complications of trauma, such as soft tissue impingement, heterotopic ossification, and synostosis.
