背景：乳房重量的增加会导致一些脊柱姿势改变，从而降低执行需要稳定平衡的动态任务的能力。乳房重量增加对假体隆胸后静态姿势的影响尚未被研究。方法：要求 40 名健康志愿者志愿者在日常生活活动中连续 6.5 小时在专用运动胸罩内佩戴不同尺寸的乳房植入物（800、400 和 300 克），每个植入物尺寸佩戴 1 天。通过物理临床检查与静态力平台分析的结合来评估姿势变化。结果：使用 400 克及以上的乳房植入物后，颈椎前凸显着增加。这种变化在 400 克和 800 克乳房植入物之间是稳定的。因此，400 克（每个乳房）的植入物可能是打破颈椎姿势生理平衡的负载阈值。仅在使用 800 克乳房植入物后才证明腰椎前凸显着增加。静力平台评估表明，使用 400 g 和 800 g 植入物时，独立于视觉控制的平衡会恶化。结论：事实证明，较重的乳房植入物会引起脊柱曲线的可逆性改变，并且 400 g 是短期内功能性生理代偿的临界值。这样的重量可能被认为是出于美容目的使用乳房植入物的安全极限。
Background: An increased weight of the breasts causes several spinal postural alterations that reduce the ability to perform dynamic tasks requiring a stable balance. The effects of the increased weight of the breasts on static posture after implant breast augmentation have not been investigated yet. Methods: Forty volunteer healthy women were asked to wear different sized breast implants (800, 400, and 300 g) inside a dedicated sports bra for 6½ consecutive hours during their everyday life activities, 1 day for every implant size. Posture changes were assessed with the association of a physiatric clinical examination with a static force platform analysis. Results: A significant increase in cervical lordosis after the use of 400-g breast implants and upward was demonstrated. This alteration was stable between the 400-g and 800-g breast implants. The 400-g (per breast) implant might therefore be the load threshold that breaks the cervical postural physiologic balance. A significant increase in lumbar lordosis was demonstrated only after the use of the 800-g breast implants. The static force platform assessment demonstrated a worsening of the balance independent from the visual control with the use of 400-g and 800-g implants. Conclusions: Heavy breast implants proved to induce reversible alterations in the spinal curve, and 400 g is the cutoff for functional physiologic compensation in the short term. Such a weight might be considered the safety limit for the use of breast implants for cosmetic purposes.
