Abstract:
Objective To investigate the advantage of the technique of static compression screws with medial support using one ordinary cannulated compression screw (OCCS) and 2 headless cannulated compression screws (HCCSs) in reducing complications in the treatment of vertical femoral neck fractures.Methods From December 2014 to July 2017,79 patients were treated at Department of Orthopaedics,The Sixth People's Hospital of Shanghai for vertical femoral neck fractures.They were 51 men and 28 women,aged from 20 to 65 years (average,49.1 years).Their injury involved 45 left sides and 34 right sides.Of them,37 were treated with one OCCS at the top and 2 HCCSs at the bottom of a triangle arrangement for fixation of the vertical femoral neck fracture (the experimental group);the other 42 were treated with 3OCCSs at a triangle arrangement for fixation of the vertical femoral neck fracture (the control group).Their fracture healing and complications were followed up at postoperative 6 weeks,3,6 12,18,24 months and any time of discomfort by anteroposterior and lateral X-ray films of the knee joint.Results The 2 groups were compatible due to insignificant differences between their preoperative general data (P ＞ 0.05).This cohort was followed up for 9 to 24 months (average,17.5 months).Of them,52 achieved fracture union.Of the 27 patients who failed,8 were in the experimental group (21.6％) and 19 in the control group (45.2％),showing a significant difference in the rate of failure between the 2 groups (P ＜ 0.05).In the experimental group,the rate of nonunion was 8.1％ (3/37),the rate of implant failure 18.9％ (7/37),and the rate of fermoral neck varus 8.1％ (3/37),all significantly lower than those in the control group [26.2％ (11/42),40.5％ (17/42) and 23.8％ (13/42),respectively] (P ＜0.05).Conclusion For treatment of vertical femoral neck fractures,the technique of static compression screws with medial support is not only easy but also leads to a lower rate of complications.
