– Avulsion frx of lateral malleolus (Weber A) – frequently does well w/ closed reduction; – w/ lateral and oblique medial malleolus injuries; – pronation of foot & abduction will reduce frx; – however, is an unstable pattern which requires operative Rx; – SER/Weber B: … Read more
– Discussion: – Non Union – General Discussion: – definition of fracture union: defined as bridging callus (ideally both cortices) on 2 orthogonal views with the disappearance of fracture lines – care must be taken not to mistake a pseudoarthrosis for a simple hypertrophic nonunion; – treatment of the pseudoarthrosis requires complete resection of the synovial tissue, and … Read more

– Discussion: – blood has has high-signal intensity on T1; – areas of high-signal intensity on T1 images generally are fat or blood; – abscesses tend to have low-intensity capsule on both T1 & T2 images – signal intensity of fluid may vary, depending on the protein … Read more
– Discussion: – few indications, except in elderly and osteoporotic patients w/ low energy extra-articular fractures; – these fractures have a high rate of hardware failure w/ operative treatment; – unfortunately, non operative treatment in elderly patients can also be associated w/ a … Read more
