Objective: To compare the clinical effect of dynamic hip screw (DHS) and cannulated compression screw (CCS) in the treatment of fresh femoral neck fracture. Methods: A retrospective study was conducted to analyze the data of 91 patients with fresh femoral neck fracture treated with DHS or CCS in our hospital from January 2012 to June 2016.The cases were divided into two groups according to internal fixation: 44 cases in the DHS group and 47 cases in the CCS group. By comparing operative time, intraoperative bleeding, postoperative load, Harris scoring and the complications such as postoperative necrosis of femoral head and shortening of femoral neck appearance, we evaluated the clinical curative effect of two kinds of fixation.
For fresh femoral neck fracture internal fixation, both DHS and CCS can make strong fixation of hip and have good recovery. There is no statistical difference in complications after surgery between the two procedures. Patients with DHS internal fixation have earlier postoperative weight bearing, which is conducive to functional exercise of the injured limb. DHS internal fixation system is recommended for patients with unstable fractures and severe osteoporosis.
