Varus External Rotation Stress Test for Radiographic Detection of Deep Deltoid Ligament Disruption With and Without Syndesmotic Disruption

Abstract

These findings may lead to improved clinical detection of rotational ankle instability from combined DDL and syndesmotic disruption, which may affect decision making for using syndesmotic fixation when using intraoperative stress fluoroscopy images. Occult DDL instability may be underdiagnosed, and this may affect future directions of the treatment of rotational ankle fractures and severe sprains.

Comparison of deltoid ligament repair and syndesmotic fixation in malleolar fractures

“…A pontuação do AOFAS ≥6 e ≥12 após a cirurgia foi de 90,5 ± 10,0 e 95 ± 4,9 para o grupo I e 88,3 ± 10,1 e 93 ± 8,4 para o grupo II (p=0,374 e 0,306), respectivamente (Tabela 3). Os resultados do EQ-5D ≥6 e ≥12 meses após a a fixação lateral do maléolo, a persistência de um ELM significativamente aumentado com ou sem diástase por sindesmose, deve-se suspeitar de que a integridade do LD tenha sido comprometida de alguma forma (18,19) . Em 2018, Rigby e Scott (16) alertaram que estressar o tornozelo medial após o reparo das fraturas era uma técnica negligenciada.…”

Discussion Concerning Deltoid Ligament and Antero-Medial Capsule Repair in the Surgical Management of Supination External Rotation Ankle Fractures

“…Varus external-rotation stress was more effective than valgus external-rotation stress in demonstrating talus lateral displacement in AP radiographs [3]. Talus anterior translation was observed by anterior-posterior stress test by pushing the distal tibia posteriorly.…”

“…Multiple fractures, medial malleolar fractures, open fractures, previous an- The radiographs show a Weber B lateral malleolar fracture without a medial malleolar fracture (1,2). CT shows no obvious anterior or lateral dislocation (3,4). Intraoperative radiographies show the medial joint space was clearly widened under the external rotation stress test (5,6).…”

Traumatic Multi Ligament Ankle Injury, Associated with a Displaced Articular Calcaneus Fracture, in the Absence of Ankle Fractures

“…The syndesomsis can be assessed by the tibio fibular overlap and the tibio fibular clear space on AP and mortise views. An external rotation stress tests is useful for assessment of the deep deltpoid ligament and the syndesmosis [14].…”
