Abstract

We report the results of osteosynthesis of femoral neck fractures with Hansson Pin. From November 2003 to December 2005, we treated 37 patients with femoral neck fractures with or without the displacement. According to the modified Gardens classification, there were six stage 1 subjects, 10 stage 2, 16 stage 3 a, three stage 3 b and two stage 4. Six were men and 31 were women, and their mean age was 76 years. Thirty fractures were united and three were switched to hemiarthroplasty. Overall union ratio was 81%: 100% in stages 1 and 2, 88% in stage 3 a, and 0% in stages 3 b and 4. The cause of non-union was poor reduction in five and bone fragility in two (steroid induced and hemodialysis). We can use Hansson Pin in minimal displacement and reducible fractures, but in irreducible cases, we should consider the merits of this method for patients with risks and bone fragility.
