Abstract
Introduction
In most cases of stable type medial femoral neck fracture and some cases of dislocated medial femoral neck fracture, internal fixation was undertaken. Dual SC Screw (DSCS) System is an internal fixation device which has sliding mechanism and preventing mechanism of back out of the screw. The purpose of this study is to evaluate the results and complication of medial femoral neck fracture treated with DSCS.
Methods
Fifty two patients operated for fractures of the medial femoral neck with DSCS were identified as the study population. All patients followed up at least 2years. Outcome measures included the period of bone union, revision surgery, operating times and clinical symptoms and complication.
Results
The average operation time was 37 minutes and 49 cased achieved union. Moreover all patients could regain the pre-injury walking ability. Three patient did not achieve union and two patients suffered displacement of reduced fracture and three patients had avascular necrosis of the femoral head. However, the cases of subtrochanteric femral fracture or the back out of the screws were not found. The mechanical tests using imitation bone showed the strength of DSCS.
Conclusion
Operative treatment with internal fixation using DSCS in femoral neck fracture gives favorable results because of its strong fixation and holding function of the screw. The operative technique was simple and the DSCS thought to be a useful tool for femoral neck fracture.
