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.
