Abstract

OBJECTIVE

To investigate a stem-adjusted preparation of the femur with a kinked reamer and to determine whether this approach results in higher primary stability of a kinked stem than straight reaming of the intramedullary canal.

METHODS

Ten cementless stems with a kinked design were implanted in synthetic femurs after preparation of the femoral canal with 2 different reamer designs (straight reaming [SR] group vs kinked reaming [KR] group). The specimens were analyzed using CT to determine the anchoring length and examined with a mechanical testing system to establish their axial stiffness, torsional stiffness, and migration distance after 10 000 gait cycles.

RESULTS

The stem migration distances did not differ significantly between the groups (SR group 0.51 ± 0.16 mm vs KR group 0.36 ± 0.03 mm, P = 0.095). Only for the SR group, a correlation was found between the completely conical anchorage length and absolute stem migration (P < 0.05, R = 0.89). Regarding the torsional stiffness, no differences were observed between the study groups (SR group 6.48 ± 0.17 Nm/° vs KR group 6.52 ± 0.25 Nm/°, P = 0.398). In the KR group, significantly higher axial stiffness values were measured than in the SR group (SR group 1.68 ± 0.14 kN/mm vs KR group 2.09 ± 0.13 kN/mm, P = 0.008).

CONCLUSIONS

The implantation of a kinked stem after kinked conical intramedullary preparation of the proximal femur showed equivalent results regarding anchoring length, stem migration, and torsional stiffness to those for straight conical reaming. The specimens with kinked reaming showed significantly higher axial stiffness values.

摘要

目的

研究股骨的 Stem-Adjusted 准备与弯形扩孔器，并确定这种方法是否会导致弯形柄比直形髓内通道扩孔具有更高的初始稳定性。

方法

10 个具有弯形设计的无水泥柄在使用两种不同扩孔器设计（直形扩孔 [SR] 组与弯形扩孔 [KR] 组）准备股骨管后被植入合成股骨中。使用 CT 分析标本以确定锚固长度，并使用机械测试系统检查它们在 10000 次步态循环后的轴向刚度、扭转刚度和迁移距离。

结果

两组间的柄迁移距离无显著差异（SR 组 0.51 ± 0.16 mm 与 KR 组 0.36 ± 0.03 mm，P = 0.095）。仅在 SR 组中，完全锥形锚固长度与绝对柄迁移之间存在相关性（P < 0.05，R = 0.89）。关于扭转刚度，研究组之间无差异（SR 组 6.48 ± 0.17 Nm/°与 KR 组 6.52 ± 0.25 Nm/°，P = 0.398）。在 KR 组中，测量到的轴向刚度值明显高于 SR 组（SR 组 1.68 ± 0.14 kN/mm 与 KR 组 2.09 ± 0.13 kN/mm，P = 0.008）。

结论

在股骨近端弯形锥形髓内准备后植入弯形柄在锚固长度、柄迁移和扭转刚度方面与直形锥形扩孔具有等效结果。具有弯形扩孔的标本显示出明显更高的轴向刚度值。
