Lauge-Hansen’s classification, which was published in a issue of Archives of Surgery, has become one of the most widely used ankle. The Lauge-Hansen classification is a system of categorizing ankle fractures based on the foot position and the force applied. Classification, Description, Notes. Supination External Rotation, Most common mechanism (% of all fractures). 1, Anterior tibiofibular ligament rupture.

Lauge Hansen Classification of Ankle Fractures
Thank you for rating! Please vote below and help us build the most advanced adaptive learning platform in medicine. In what direction is the fibula most unstable? Which of the bone fragments labeled on the distal tibia in the axial CT scan shown in Figure A is dlassification to the posterior tibiofibular ligament?
Past medical history includes insulin dependent diabetes mellitus for 35 years. On physical examination the patient is unable to feel a 5. His pedal pulses are palpable. Of the following options, what would be the recommended treatment? Open reduction and internal fixation with restricted weight bearing for 2 weeks.
Open reduction and internal fixation with restricted weight bearing for 6 weeks. Open reduction and internal fixation with restricted weight bearing for 12 weeks. His radiograph is shown in figure A.
What is the most appropriate definitive treatment? Open clsasification and internal fixation of the medial malleolus with syndesmosis reduction and suture-button repair. Open reduction internal fixation of the fibula with syndesmosis reduction and suture-button repair. Open reduction internal fixation of the fibula and medial malleolus with syndesmosis reduction and suture-button repair.
Ankle Fractures – Trauma – Orthobullets
What is the mechanism for the fracture pattern shown in Figure A? CT scans note anteromedial marginal impaction. Which radiograph Figures A-E would best correlate with this finding? Fibular plating with open correction of plafond impaction with laugge malleolar antiglide plate. Fibular plating with open correction of syndesmosis and oblique medial malleolar screws. Which of the following is most appropriate step based on Figures A and B?
Radiographs from classifixation ER are provided in figures A and B. Four hours later, he undergoes open reduction internal fixation. An intraoperative fluoroscopy image is provided in figure C. Which of the following is the best method to assess the integrity of the syndesmosis? Which of the following is unique aluge this particular ankle fracture pattern and must be recognized by the operating surgeon to optimize outcomes? An AP and lateral radiograph are shown in figures A and B respectively.
The attempted post reduction AP and lateral are shown in C and D.
What structure is most likely preventing reduction? A radiograph of her ankle is shown in Figure A. Recommended management should consist of? What is an advantage of using lateral neutralization plating instead of posterior antiglide plating? What is the most reliable method to evaluate the competence of the deltoid ligament?
Her postoperative radiographs are shown in Figure A. Widening of the tibia-fibular clear space with external rotation stress would be a result of injury of which structure? He subsequently undergoes surgical fixation, and a post-operative radiograph is shown in Figure A. At the eight-week postoperative visit, you are asked to fill out a return to work form.
He returns to clinic five months following surgery complaining of continued ankle pain and instability with weight bearing. His immediate post-operative AP radiograph is seen in Figure A. Which of the following could have prevented this patient from developing persistent pain?
An AP ankle radiograph is provided in Figure A. Which of the following statements accurately describe this radiograph? The fracture is consistent with a Lauge-Hansen pronation-external rotation injury pattern.
Injury to what structure should be evaluated intraoperatively during fixation of the fibula? Diagnosis, Reduction, and Fixatio This is an example of spanning external fixation used for ankle, pilon and other Supramalleolar Osteotomy for Coronal Deformity: HPI – Initial trauma was 3 months ago.
Patient was not treated properly because she was in a remote area. Partial weight classificatjon starting 1 week after the trauma. Full weight bearing now.
How would you manage this patient given she is now 3 months from the injury? HPI – While walking the patient hanssn her ankle and had a bimaleolar ankle fracture 6 months ago. She progressed well until 2 months ago when she notes heel deformity and ankle swelling.
What is your diagnosis? HPI – Heavy weight injury 18 days ago, immediate pain, swelling ; diagnosed with left ankle fracture. Is this a case of a simple lateral malleolus fracture? Please vote below and help us build the most advanced adaptive learning platform in medicine The complexity of this topic is appropriate for?
L6 – years in practice. L7 – years in practice. L8 – 10 years in practice. How important is this topic for board examinations? How important is this topic for clinical practice? Core Tested Community All.
