Abstract

The aim of this work is to provide cumulative data about the efficacy and safety of Cannulated Screws (CS) Vs Dynamic Hip Screw (DHS) for treatment of femoral neck fractures.
Meta-analysis study was done on 17 studies which described and compared the 2 different techniques for femoral neck fractures; with overall number of patients (N= 54453).
Regarding 1ry efficacy outcome measures,
• We found 10 studies(28,29,32,1,35,38,39,40,41,31) reported union (success rate). The random-effects model of the meta-analysis study showed non-significant difference in union (success rate) in DHS group compared to CS group (p > 0.05).
• We found 8 studies(33,35,39,42,1,40,29,31) reported Harris Hip score. The random-effects model of the meta-analysis study showed non-significant difference in mean Harris Hip score in DHS group compared to CS group (p > 0.05).
• We found 9 studies(32,1,35,38,28,29,31,40,41) reported time of radiological union. The random-effects model of the meta-analysis study showed non-significant difference in mean time of radiological union in DHS group compared to CS group (p > 0.05).
• We found 2 studies(31,1) reported Garden alignment index. The fixed-effects model of the meta-analysis study showed non-significant difference in mean Garden alignment index in DHS group compared to CS group (p > 0.05).
Regarding 2ry safety outcome measures,
• We found 10 studies(28,29,32,1,35,38,41,31) reported non-union (failure rate). The fixed-effect model of the meta-analysis study showed insignificant difference in nonunion between both groups (Risk ratio: 0.69, 95% CI 0.40-1.19)
• We found 17 studies(1,7,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42) reported INFECTION rate. the fixed-effect model of the meta-analysis showed non significant difference between DHS group and MCS group.
• We found 17 studies(1,7,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42) reported AVN rate. The fixed-effects model of the meta-analysis study showed significant increase in risk of AVN in DHS group.
• We found 2 studies(34,41) reported revision surgery rate. The fixed-effects model of the meta-analysis study showed non-significant difference in revision surgery rate in DHS group compared to CS group (p > 0.05).
• We found 3 studies(31,37,40) reported DVT rate. The fixed-effects model of the meta-analysis study showed significant increase in risk of DVT in DHS group.
• We found 2 studies(39,42) reported SCREW LOOSENING rate. The fixed-effects model of the meta-analysis study showed significant increase in risk of SCREW LOOSENING in MCS group.
• We found 5 studies(35,36,39,41,42) reported Screw Cut in. the fixed-effects model of the metal-analysis showed insignificant difference between DHS group and MCS group
Limitations
• The retrospective design and the comparatively low number of patients who met the inclusion criteria in some studies.
• Lack of follow up in some studies.
• Small sample size in some studies
