中文摘要:

目的:探索骨质疏松条件下叠加锚钉置入是否能提高锚钉的把持力,以期为临床解决伴有骨质疏松的肩袖损伤的治疗。

方法:选取21个同种异体骨质疏松股骨头标本,男13例,女8例;年龄60~95(77.6±10.3)岁;左侧9例,右侧12例。将骨模块分为3组,每组7个。拧入单枚锚钉(A组);拧入并联的2枚锚钉(B组);拧入单枚锚钉,在拔出锚钉后,重新拧回锚钉,并紧贴该钉再拧入1枚锚钉(C组)。置钉后3组均进行X线检查,观察锚钉在骨质疏松模块中的情况;随后进行力学试验,测量3组的最大轴向拔出力(Fmax)。

结果:A、B、C组Fmax分别为(170.35±31.21)、(314.47±23.47)、(292.74±25.36) N。与A组相比,B、C组 Fmax差异有统计学意义(P<0.05),而B组与C组Fmax比较差异无统计学意义(P>0.05)。

结论:在骨质疏松模块中锚钉松动的情况下通过叠加锚钉可提高锚钉的把持力。该方法可为临床手术时单锚钉失效提供一种补救方法。

Experimental study on improving stability of anchor by adding anchor
ABSTRACT  

Objective: To explore whether anchor placement could improve holding force of anchors under the condition of osteoporosis,in order to solve the problem of clinical treatment for rotator cuff injury associated with osteoporosis.

Methods: Twenty one bone modules,which included 13 males and 8 females aged from 60 to 95 years old with an average of (77.6±10.3) years old,and were divided into three experimental groups named as group A,B and C,and 7 in each group.A single anchor was inserted in group A,two parallel anchors were screwed in group B,and a single anchor was screwed in group C,then after the anchor was pulled out,anchor was screwed back and another anchor was screwed in close to the anchor.X-ray examination was performed in all three groups to observe situation of anchor in osteoporosis module;the maximum axial pull-out force (Fmax) of the three groups was measured.

Results: Fmax of group A,B and C was (170.35±31.21) N,(314.47±23.47) N,and (292.74±25.36) N,respectively.Compared with group A,there were statistical difference of Fmax in group B and C (P<0.05),while no difference of Fmax between group B and C (P>0.05).

Conclusion: In the case of loose anchors in the osteoporosis module,holding force of anchors could be improved by adding anchor,which provide a remedy for single anchor failure in clinical operation.
