Unilateral mastectomy induces postural alterations; however, the resolution of this issue in clinical settings remains unknown. This study aimed to explore the effects of wearing external breast prosthesis on the posture of patients after unilateral mastectomy.
A total of 240 patients who underwent unilateral mastectomy for breast cancer in our hospital's breast surgery department from September 2020 to March 2021 were selected, and they were registered and randomized in a 1:1 ratio to receive one of two treatments: (1) the intervention group wearing a external breast prosthesis (similar in weight to the breast) and (2) the control group wearing a cotton breast prosthesis (almost no weight). The generalized estimating equation method was used to analyze the impact of wearing external breast prosthesis on the patients' body posture 3 and 6 months after the intervention.
Statistically significant differences were observed between the two groups regarding forward head posture, shoulder asymmetry, scapular tilt, and neck tilt (P < 0.05). However, the two groups had no significant differences in scapular adduction/abduction, pelvic tilt, and trunk inclination (P > 0.05). Over time, all degrees of deviation in postural abnormalities exhibited an upward trend, with postural abnormalities becoming increasingly serious.
External breast prosthesis can improve postural abnormalities in patients with forward head posture, shoulder asymmetry, and scapular and neck tilts. However, there was no significant improvement in the short-term body posture of the patients concerning scapular adduction/abduction, pelvic tilt, or trunk inclination, indicating that further research is required to understand the effects of wearing external breast prosthesis on patients' body posture.

单侧乳房切除术会引起姿势改变；然而，在临床环境中该问题的解决方法仍不明确。本研究旨在探讨佩戴外部乳房假体对单侧乳房切除术后患者姿势的影响。
选取2020年9月至2021年3月在我院乳腺外科接受单侧乳腺癌乳房切除术的240例患者，将他们登记并按1:1比例随机分为两组接受两种治疗之一：（1）干预组佩戴外部乳房假体（重量与乳房相似）；（2）对照组佩戴棉质乳房假体（几乎无重量）。采用广义估计方程法分析干预后3个月和6个月佩戴外部乳房假体对患者身体姿势的影响。
两组在头部前倾姿势、肩部不对称、肩胛骨倾斜和颈部倾斜方面存在统计学显著差异（P<0.05）。然而，两组在肩胛骨内收/外展、骨盆倾斜和躯干倾斜方面无显著差异（P>0.05）。随着时间推移，姿势异常的所有偏差程度均呈上升趋势，姿势异常越来越严重。
外部乳房假体可改善头部前倾姿势、肩部不对称以及肩胛骨和颈部倾斜患者的姿势异常。然而，患者在肩胛骨内收/外展、骨盆倾斜或躯干倾斜方面的短期身体姿势无显著改善，这表明需要进一步研究以了解佩戴外部乳房假体对患者身体姿势的影响。
