Pathologic Malgaigne fracture following pelvic irradiation. A case report.

abstract：:External malrotation is a frequent complication following Ender nailing. Biomechanical studies demonstrate that the standard Ender nail tends to produce external malrotation when the fracture is unstable. This type of malrotation does not develop to the same degree if the nails are bent into a 25 degree angle of antev...
