Detection of fibular torsional deformities after surgery for ankle fractures with a novel CT method.

Background: Substantial fibular torsional deformities were detected after surgery for ankle fractures combined with a lesion of the syndesmotic complex using a novel CT analyzing method.

Methods: In a prospective study, 61 patients with ankle fracture dislocations were treated with trans-syndesmotic screw fixation of the distal tibiofibular joint. Postoperative axial CT scans of both lower legs under standardized leg positioning conditions were made and analyzed with three different methods.

Local cooling restores microcirculatory hemodynamics after closed soft-tissue trauma in rats.

Background: Severe closed soft-tissue injury (CSTI) results in progressively developing microvascular dysfunction and local inflammation. Cooling reduces swelling, pain, cellular oxygen demand, and metabolic activity. However, effects of cooling on posttraumatic microcirculation are not yet fully understood.
