Multiple cannulated screw fixation of young femoral neck fractures.

OBJECTIVE We wanted to analyze the factors affecting the results of multiple cannulated screws fixation in patients less than 60 years old with femoral neck fracture (FNF). METHODS We reviewed 52 patients (30 males, 22 females) who were treated with multiple cannulated screws fixation for FNFs. They were followed up for more than one year during January 2002 to December 2012. They were classi...

Cannulated versus non-cannulated cancellous screw fixation for femoral neck fractures: a synthetic bone biomechanical study

Purpose. To compare the compressive strength of cannulated versus non-cannulated cancellous screws for undisplaced femoral neck fractures in synthetic bones. Methods. 18 synthetic proximal femurs simulating an AO B1 valgus impacted femoral neck fracture in osteoporotic bone were used. The fracture angles were between 55o and 63o (Pauwels grade 2). Fixation was made using 6.5-mm non-cannulated s...

Comparing Therapeutic Outcomes of Dynamic Hip Screw and Multiple Cannulated Screws as Internal Fixation in Femoral Neck Fractures

Background and purpose: Femoral neck fracture is associated with a high rate of side effects, especially in young people, who are usually affected by severe energy shocks. Results after injury depend on some factors, including displacement, fragility, bleeding rate, proper placement, and stable and strong fixation. The aim of this study was to compare dynamic hip screw (DHS) or multiple cannula...

Subchondral screw fixation for femoral neck fractures.

We describe a method of internal fixation for femoral neck fractures which has been newly developed to reduce the frequency of early complications. Two cannulated screws are inserted in the axis of the femoral neck to reach into the subchondral bone of the femoral head. The screws are inserted over guide pins and the tip of the screw is self-tapping and designed to provide good anchorage in the...
