Nonunion of subcapital femoral neck fractures.

Abstract

One hundred forty-one patients were reviewed following osteosynthesis of their femoral neck fractures. All cases had been pinned using three or four short threaded 6.5 mm AO screws. It was found that those fractures with a vertical configuration, particularly in the males, showed a high rate of nonunion. It is concluded that simple pin fixation is not adequate for this specific group of patients.
