Why the study?
Do von Bahr or Gouffon screws reduce the failure rate compared to Hessel pins in patients with femoral neck fractures?
Do von Bahr or Gouffon screws reduce the failure rate compared to Hessel pins in patients with femoral neck fractures?
Nonthreaded Hessel pins are inferior to von Bahr and Gouffon screws for the fixation of femoral neck fractures due to a higher failure rate.

Avoid nonthreaded Hessel pins for femoral neck fracture fixation; confirms threaded screws reduce failure risk.
We report a prospective study of 214 patients with femoral neck fractures operated on with multiple pinning. The fractures were randomly allocated to fixation with either von Bahr screws or Hessel pins in 1983 and 1984 or von Bahr or Gouffon screws in 1984 and 1985. After 2 years, the failure rate was one third in the von Bahr and the Gouffon screw groups and one half in the Hessel pin group. We conclude that the nonthreaded Hessel pin is inferior to the von Bahr and Gouffon screws for fixation of femoral neck fractures.
