Abstract:
Objective To investigate the value of G-arm X-ray machine assisted percutaneous minimally invasive screw fixation in cannulated screws of femoral neck fractures. Methods The adult femoral neck fractures ( 64 cases) treated with percutaneous cannulated screws were retrospectively collected. Thirty-three cases assisted by ?uoroscopy of G-arm X-ray machine in the placement of percutaneous cannulated screws were recorded as the G-arm group. Thirty-one cases assisted by ?uoroscopy of C-arm X-ray machine in the placement of percutaneous cannulated screws were recorded as the C-arm group. Harris score was used to evaluate the hip function. The intraoperative operating X-ray machine times, operative time, postoperative hospital stay, pain visual analogue score and Harris score at the last follow-up were compared. Results Both group' s operations were successfully completed. The G-arm group had 31 cases of anatomical reduction, 2 cases of functional reduction, while the C-arm group had 28 cases of anatomical reduction and 3 cases of functional reduction. All patients were followed up for an average of ( 5 . 7 ± 0 . 6 ) months. In the G-arm group, the intraoperative operating X-ray machine times (t=6.287, P=0.000) and operation time (t=6.482, P=0.000) were less than those in the C-arm group (P < 0. 05). There was no signi?cant difference in the postoperative hospital stay (t =0.568, P = 0 . 571 ), pain visual analogue scale (t =0.530, P = 0 . 597 ) and Harris score (t =0.714, P = 0 . 477 ) at the last follow-up between the two groups (P >0.05). Conclusion The use of G-arm X-ray machine assisted the placement during cannulated screws ?xation for femoral neck fractures has the advantages of fewer intraoperative operating X-ray machine times and shorter operative time, and can achieve satisfactory therapeutic results.
