Overview

ASIF screws improve union in displaced femoral neck fractures; confirms advantage over sliding screw plate in this RCT.

Structured PICO

Does fixation with 4 ASIF cancellous bone screws improve the rate of union compared to a sliding screw plate in patients with displaced femoral neck fractures?

P
Population
103 patients with displaced femoral neck fractures (nonpathologic, Garden's Stages 3 and 4, delay <24 hours for Stage 4), mean age 74-75 years.
I
Intervention
Fixation with 4 ASIF cancellous bone screws
C
Comparator
Fixation with a sliding screw plate (SSP)
O
Outcome
Time of union / cumulated rate of union at 2 yearshard clinical

Fixation of displaced femoral neck fractures with 4 ASIF cancellous bone screws resulted in a significantly higher 2-year union rate compared to a sliding screw plate.

Limitations

  • Small sample size leading to risk of type II error for secondary outcomes like late segmental collapse
