No results posted yet for this study

Summary

This study is a prospective randomized controlled clinical study. Patients with femoral neck fracture (AO classification 31-B) will be randomly divided into three-screw fixation group and four-screw fixation group. The internal fixation failure rate (IFFR) and functional outcomes of the two groups will be compared and the patients will be followed up to 2 years after surgery.

Conditions

  • Femoral Neck Fractures
  • Internal Fixation

Interventions

DEVICE

three cancellous screws

All patients with femoral neck fractures will be randomly divided into 2 groups at a ratio of 1:1. Three screws for internal fixation in the three-screw group, and three cancellous screws with an inverted triangle pattern are used to fix the fracture of femoral neck.

DEVICE

four cancellous screws

All patients with femoral neck fractures will be randomly divided into 2 groups at a ratio of 1:1. Four screws for internal fixation in the four-screw group, and the fourth screw will be implanted in the horizontal direction of the femoral distance on the basis of the three screws.
