Correlation of Incisura Anatomy With Syndesmotic Malreduction

Boszczyk, Andrzej, Kwapisz, Sławomir, Krümmel, Martin, Grass, Rene, Rammelt, Stefan 29 October 2019 (has links)
Background: The anatomy of the syndesmosis is variable, yet little is known on the correlation between differences in anatomy and syndesmosis reduction results. The aim of this study was to analyze the correlation between syndesmotic anatomy and the modes of syndesmotic malreduction. Methods: Bilateral postreduction ankle computed tomography (CT) scans of 72 patients treated for fractures with syndesmotic disruption were analyzed. 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. Results: Clinically relevant malreduction in the coronal plane, sagittal plane, and rotation affected 8.3%, 27.8%, and 19.4% of syndesmoses, respectively. 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. Conclusions: Certain morphologic configurations of the tibial incisura increased the risk of specific syndesmotic malreduction patterns. Level of Evidence: Level III, comparative study.

Approches arthroscopiques et description de l'anatomie articulaire normale du carpe et du tarse chez le bovin adulte

Lardé, Hélène 04 1900 (has links)
Les approches arthroscopiques et l’anatomie normale des articulations antébrachiocarpienne, carpienne moyenne et tarsocrurale n’ont jamais été décrites spécifiquement chez les bovins. Notre étude avait pour buts de définir les abords chirurgicaux et de décrire l’anatomie arthroscopique de ces trois articulations. Deux carpes et deux tarses issus du cadavre frais d’une vache adulte ont été injectés avec un mélange de latex, puis disséqués afin de déterminer les sites arthroscopiques d’intérêt. Par la suite, l’arthroscopie des articulations antébrachiocarpienne et carpienne moyenne (approche dorsale) et de l’articulation tarsocrurale (approches dorsale et plantaire) a été réalisée sur six cadavres frais de vaches adultes ne présentant ni boiterie ni distension articulaire avant leur euthanasie. Les approches dorsolatérale et dorsomédiale des articulations antébrachiocarpienne et carpienne moyenne ont été réalisées de part et d’autre de l’extenseur radial du carpe. Les structures observées étaient le radius distal, les os radial, intermédiaire, ulnaire, II et III fusionnés et IV du carpe, ainsi que des ligaments palmaires. Les approches dorsolatérale et dorsomédiale de l’articulation tarsocrurale ont été réalisées latéralement au long extenseur des doigts et médialement au troisième péronier respectivement. Les approches plantarolatérale et plantaromédiale ont été réalisées latéralement au fléchisseur latéral des doigts et latéralement au fléchisseur médial des doigts respectivement. Les structures observées étaient le tibia distal, les trochlées proximale et plantaire du talus, le processus coracoïde du calcanéus, l’articulation fibulo-calcanéenne et des ligaments articulaires. Quelle que soit l’articulation, l’approche latérale était préférée à l’approche médiale. L’arthroscopie du carpe et du tarse pourra être proposée dans un contexte hospitalier comme outil diagnostique, thérapeutique et pronostique des maladies articulaires bovines. / Arthroscopic approaches and normal anatomy of the antebrachiocarpal, middle carpal and tarsocrural joints have not been specifically described in cattle. Our study aimed to determine surgical approaches and to describe the arthroscopic anatomy of these three joints. Two carpi and two tarsi from the fresh cadaver of an adult cow were injected with a latex mixture and dissected to determine the arthroscopic sites of interest. Thereafter, arthroscopic evaluation of the antebrachiocarpal and middle carpal joints (dorsal approach) and tarsocrural joint (dorsal and plantar approaches) was performed on six fresh cadavers of adult cows exhibiting neither lameness nor joint distension prior to their euthanasia. Dorsolateral and dorsomedial approaches of the antebrachiocarpal and middle carpal joints were performed on either side of the extensor carpi radialis. Observed structures were the distal radius, the radial, intermediate, ulnar, fused second and third and fourth carpal bones, as well as palmar ligaments. Dorsolateral and dorsomedial approaches of the tarsocrural joint were performed laterally to the extensor digitorum longus and medially to the peroneus tertius respectively. Plantarolateral and plantaromedial approaches were performed laterally to the flexor digitorum lateralis and laterally to the flexor digitorum medialis respectively. Observed structures were the distal tibia, proximal and plantar trochleae of the talus, the coracoid process of the calcaneus, the fibulocalcaneal joint and intra-articular ligaments. Whatever the joint, the lateral approach was preferred to the medial one. Arthroscopy of the carpus and tarsus may be offered in a hospital setting as a diagnostic, therapeutic and prognostic tool for bovine joint diseases.
