Can experts in acetabular fracture care determine hip stability after posterior wall fractures using plain radiographs and computed tomography?
Orthopedic traumatologists expert in acetabular fracture care cannot adequately determine hip stability status for fractures involving 20%-50% of the posterior wall using plain radiographs, computed tomography, and the patient's hip dislocation status. If the diagnosis is in doubt, open reduction and internal fixation clearly is the much safer course than nonoperative treatment. Examination under anesthesia should be considered as a helpful addition to the surgeon's armamentarium in determining hip stability status for these fractures.
These results suggest that methylproamine acts by preventing the formation of DNA double-strand breaks (dsbs) and support the hypothesis that radioprotection by methylproamine is mediated, at least in part, by decreasing initial DNA damage.
