Abstract
Aims
Dual SC Screw (DSCS) is a novel fixation device for the femoral neck fracture. DSCS is comprised of screw and barrel allowing sliding of the screw and preventing protrusion of the screw end. Two types of the barrels are available, threaded barrel (TB) and plate barrel (PB). Ordinarily, both barrels are implanted. Concept of the design is that the PB contributes stability to the screw against the varus force of the femoral head while the additional screw with TB prevents rotational deformity. The aim of this study was to represent clinical results after DSCS operation in patients with femoral neck fracture.
Method
Fifty-one patients with femoral neck fractures treated using DSCS and at least 3 months follow up are included and their clinical was evaluated.
Result
Most fractures healed uneventfully. Cut out was occurred in two patients, perforation of the femoral head in one, femoral head necrosis in two, subtrochanteric fracture in one and 1backout of screw in one. The cases except that are excellent postoperative results.
Discussion and Conclusion
Most complication was associated with some technical problems and all but one patients without that showed excellent results even for displaced fracture. Furthermore, secondary subtrochanteric fracture was rare compared other devices.
The plate augmentation for screw fixation contributes to these excellent results.
