Abstract

BACKGROUND

Early full weight-bearing mobilization is controversial in osteoporotic patients who have undergone uncemented hemiarthroplasty (UCH).

OBJECTIVES

The aim of the study was to compare the results of early full weight-bearing mobilization in CH and uncemented hemiarthroplasty (UCH). The effect of subsidence on the results was also evaluated.

METHODS

Fifty-nine patients who underwent CH and UCH were evaluated. The mean age was 79.8 years (10 females, 15 males) for CH and 75.5 years (10 females, 24 males) for UCH. All patients started immediate full weight-bearing mobilization and weight-bearing exercises.

RESULTS

There was no difference between the groups according to the Harris Hip Score. Both groups were evaluated in subgroups according to whether there is varus in the femoral stem. There was no difference between subgroups according to the Harris Hip Score. The femoral subsidence was not determined in CH group. In the UCH group, the subsidence was 1.13 ± 1.03 mm in varus femoral stem subgroup and 0.81 ± 0.85 mm in without femoral stem varus subgroup. There was no difference in subsidence between femoral stem with varus and without varus. The subsidence did not affect the Harris Hip Score.

CONCLUSION

Full weight-bearing mobilization could be safely preferred in UCH, as in CH. Femoral stem varus below 5 degrees does not affect the results and subsidence.

摘要

背景

在接受非骨水泥半髋关节置换术（UCH）的骨质疏松患者中，早期完全负重活动存在争议。

目的

本研究旨在比较早期完全负重活动在 CH 和非骨水泥半髋关节置换术（UCH）中的结果。还评估了沉降对结果的影响。

方法

对 59 例接受 CH 和 UCH 的患者进行评估。CH 的平均年龄为 79.8 岁（女性 10 例，男性 15 例），UCH 的平均年龄为 75.5 岁（女性 10 例，男性 24 例）。所有患者均开始立即完全负重活动和负重锻炼。

结果

根据 Harris 髋关节评分，两组之间没有差异。根据股骨柄是否存在内翻，将两组分为亚组进行评估。根据 Harris 髋关节评分，亚组之间没有差异。CH 组未确定股骨沉降。在 UCH 组中，在股骨柄内翻的亚组中，沉降为 1.13±1.03mm，在没有股骨柄内翻的亚组中，沉降为 0.81±0.85mm。股骨柄内翻和无内翻的沉降无差异。沉降不影响 Harris 髋关节评分。
