Dual lag screw cephalomedullary nail versus the classic sliding hip screw for the stabilization of intertrochanteric fractures. A prospective randomized study
This study is a r and omized prospect i ve study comparing two fracture fixation implants , the extramedullary sliding hip screw ( SHS ) and the dual lag screw cephalomedullary nail , in the treatment of intertrochanteric femoral fractures in the elderly . One hundred and sixty-five patients with low-energy intertrochanteric fractures , classified as AO/OTA 31A , were prospect ively included during a 2-year period ( 2005–2006 ) . Patients were r and omized into two groups : group A included 79 hip fractures managed with sliding hip screws and group B included 86 fractures treated with cephalomedullary nails .  Delay to surgery , duration of surgery , time of fluoroscopy , total hospital stay , implant-related complications , transfusion requirements , re-operation details , functional recovery , and mortality were recorded . The mean follow-up was 36 months ( 24–56 months ) . The mean surgical time was statistically significantly shorter and fluoroscopy time longer for the group B. No intraoperative femoral shaft fractures occurred . There was no statistically significant difference in the functional recovery score , reoperation , and mortality rates between the 2 groups . A new type of complication , the so-called Z-effect phenomenon , was noticed in the cephalomedullary nail group . There are no statistically significant differences between the two techniques in terms of type and rate of complications , functional outcome , reoperation and mortality rates when comparing the SHS and the cephalomedullary nail for low-energy AO/OTA 31A intertrochanteric fractures . Our data do not support recommendations for the use of one implant over the other
