Effects of fixation with F shape hollow nails versus with traditional parallel nails for patients with femoral neck fractures
Objective To observe the effects of different hollow nail distribution techniques in open reduction and internal fixation for patients with femoral neck fractures and the influence on hip joint function and fracture healing.Methods One hundred and twenty patients with femoral neck fractures admitted to Xinyang 154th Hospital from May 2021 to May 2022 were selected for the randomized controlled trial.The patients were divided into group A and group B by lottery,with 60 cases in each group.There were 32 males and 28 females in group A;they were(55.26±5.17)years old;the fracture course was 2-14(8.33±0.21)d;there were 27 cases of type Ⅰ and Ⅱ and 33 cases of type Ⅲ and Ⅳ of Garden fracture typing.There were 30 males and 30 females in group B;they were(55.31±5.22)years old;the fracture course was 3-13(8.35±0.16)d;there were 25 cases of type Ⅰ and Ⅱ and 35 cases of type Ⅲ and Ⅳ of Garden fracture typing.Group A took the fixation by traditional parallel nails,and group B by F shape hollow nails.The surgical conditions,postoperative hip joint function recovery,fracture healing within 3 months after surgery,and postoperative complications were compared between the two groups.t and x2 tests were used.Results There were no statistical differences in the surgical time,intraoperative bleeding volume,and intraoperative irradiation time between the two groups(all P＞0.05).Before the surgery,there were no statistical differences in the scores of pain,function,malformation,and joint movement range between the two groups(all P＞0.05).After the surgery,the scores of pain,function,malformation,and joint movement range in group B were higher than those in group A[(38.74± 0.82)vs.(38.41±0.25),(40.56±0.83)vs.(40.27±0.22),(3.57±0.88)vs.(3.25±0.31),and(3.61±0.85)vs.(3.36±0.25)],with statistical differences(t=2.982,2.616,2.657,and 2.186;all P＜0.05).Under different fixation techniques,the fracture healed rate within 3 months after the surgery and the fracture healing time in group B were better than those in group A[86.67％(52/60)vs.68.33％(41/60)and(4.25±0.31)months vs.(4.58±0.86)months],with statistical differences(x2=5.175;t=2.796;both P＜0.05).The incidence of postoperative complications of group B was lower than that of group A[6.67％(4/60)vs.8.33％(11/60)],with a statistical difference(x2=6.215;P=0.013).Conclusion Compared with traditional parallel nails,the application of F shape hollow nails in open reduction and internal fixation for patients with femoral neck fractures has better effect,and is of positive significance in promoting their recovery of hip joint function,accelerating the process of fracture healing,and reducing the risk of postoperative complications.
