2 Disclosure We have no potential conflicts with this presentation

3 Introduction Isolated LM fx CTX vs OP Assessment of stability is very important for proper treatment SER II SER IV

4 Introduction Tools for stability assessment Ultrasound Stress X-ray MRI Arthroscopy Low cost Pain High cost Invasive Dynamic provocation Dynamic? High cost Not invasive Not painful

5 Purpose To evaluate the value of ultrasound for stability assessment of isolated lateral malleolar fractures, compared to simple x-ray, stress radiography and arthroscopy AITFL Deltoid

6 Material and Methods From May 2016 to Nov /19 : CTx 15/19 : ORIF and AS exam (2 deny) Male : Female =7:6 Gender Male Female Mean age : 32.4(17-55) years 46% 54%

7 Material and Methods Flow chart

8 Results Number of Positive results (n=13) Simple X-ray 11/13 Stress X-ray 2/2 Ultrasound (AITFL) 12/13 Ultrasound (Deltoid) 10/13 Arthroscopy (AITFL) 11/13 Arthroscopy (IOM) 11/13 Arthroscopy (PITFL) 0/13 Arthroscopy (Deltoid) 9/13

9 Discussion US finding is similar to Arthroscopic findings AITFL 92.3% for tear 100% for complete tear Deltoid 76.9% for tear 100% for complete tear

10 Discussion Not all fracture have Deltoid ligament injury Unstable Ankle Fracture SER IV 3 / 13 : SER IV

11 Conclusion Ultrasound could be helpful for assessment of stability of isolated LM fracture. Even in stage II SER ankle fracture, could be unstable
